Following are the thing which I am expecting to be installed on your machine.

• openldap
• php-ldap module
• phpldapadmin [just to cross check functionality]

LDAP is having their own structure of managing and maintaining the hierarchy. each level of representation have their pre defined schemas. These schemas are written in /etc/openldap/ldap.conf & /etc/openldap/slapd.conf both of these files are only accessible to root. Please note that I have made this development in linux operating system so all documentation written here are base of linux things.

Now As development point of view. if you want to make the working environment on your local machine you have to perform following details.

Now first step is to configure slapd.conf just login as root and open this file for edit and you will see first 4-5 lines which represent their schemas

include /etc/openldap/schema/corba.schema
include /etc/openldap/schema/core.schema
include /etc/openldap/schema/cosine.schema
include /etc/openldap/schema/duaconf.schema

Please note that every ldap having different set have schemas. so depending upon their ldif file has to be written. Here I have considered default installation made in fedora 13. basically ldap stores in details in light weight database structure bdb (burckley DB) or ldbm. Here I have considering bdb.

in slapd.conf file you will find these lines.

database bdb
suffix "dc=runwalsoft"
rootdn "cn=root,dc=runwalsoft"

Might be dc and cn will be different machine to machine. Note that dc is suppose to be domain name. let say if you have your server as something.com then dc will be dc=something,dc=com. There are few terminologies which you need to understand here.

dn = Distinguished Name, cn = common name, rdn = relative distinguish name, dit = directory information tree, slapd = standalone LDAP.

Now In the same file you will find "rootpw" this is main admin password for ldap. In *nix system admin is always called as root. so machine root and ldap root you can seperate it. and its password you can set with line as follow

rootpw {SSHA}sDH698lRKptqw6d1uFmAKifrgZnvlcGc

Here ssha is encryption which is used. for setting new password you can use slappasswd command. when you type this in terminal they will give you some encryption for it.

Few lines at bottom you will find word directory so this is directory path where the actually directory is stored. now last but not the least at the bottom you will have to give others to access this ldap. if you don’t give access to ldap rest of the things will not be possible to use it.

access to * by dn.exact="cn=root,dc=runwalsoft" read by * none

With the above line we are allowing people(inhouse users) to use access ldap structure. Now this is all you have configured ldap configuration. Now its main part is to add users or information into ldap. but before that you need to be sure whether whether ldap is working properly or not.

on services make sure you have enabled slapd service. or you can from command prompt start slapd service

service slapd restart

Always make one thing sure that whatever you made changes in any conf file you have to restart that service.

How to see whether ldap is properly configured or not ?

Just open terminal(command prompt) and type following code

ldapsearch -x -b '' -s base '(objectclass=*)'

In that output if you see dc then it means that functionality is proper. and configuration is made proper.

Now next part is to add ldap details e.g. user and other information. Now you have to know that every information which we are going to save it has to work with schemas which is included in slapd.conf file.

Lets create one file "working.ldif" where we are going to add following set of code.

Now next part will be adding this working.ldif file to ldap structure for that you need to use following command.

ldapadd -x -D "cn=root,dc=runwalsoft" -w-f working.ldif

After that this will ask for root’s password. enter the password, and done. things are working. now…

how to see structure of our newly created ldap ?.

a) Either you can use php program or b) you can use phpldapadmin

before making the program. I hope you have installed phpldapadmin when you try to visit site http://localhost/phpldapadmin you will see it is asking for login dn and Password

Now dn is the thing which you have written in slapd.conf file so in dn box you have to write the following things.

cn=root,dc=runwalsoft

and in password write down the password . I am expecting that this will allows you to connect and make it working. now let say if you don’t want to login with root then also you can properly use phpldapadmin. just in dn you have to write complete path.

cn=user1,ou=people,dc=runwalsoft

and in pasword : user1

this also allows you to connect to ldap. please note that phpldapadmin only allows you to view bottom childs of your hierarchy and not the parent.

Now you will notice that when we try to create child node for ldap structure we have to use their objectClass so these objectClass differs from schema to schema. Now in the next blog you will learn how to connect ldap using php.

If you have any question don’t hesitate to ask me. I will respond your comments.

As most of the websites having some kind of relational database. where their is one master table. and their keys are used in other tables. But if the programmer don’t know about the foreign keys then they write the code at the time of deleting the record e.g

Lets imagine that We have 2 tables

1. Books
2. Purchasers

people write following syntax.

create table books ( id smallint primary key auto_increment , name varchar(100));
create table purchasers (id smallint primary key auto_increment , bookid smallint , pur_name varchar(100));

While creating this, many programmer forgot major things. as they are creating these tables with storage engine as myISAM. but they forgot all transactional details need to be saved in InnoDB.  and current released version’s of mysql support foreign key for only innodb. and Now php is being concern they write code for 2 sql statement for deleting books and their purchasers. this is really bullship.

Now We have seen that when we got the work for existing websites. we seen similar things in many cases( almost all the cases). this really increases lots of efforts in programming as well as maintaining the codes. For owner of websites , they don’t bother(rather they don’t know) what other/older programmers written on it.  this increases our efforts even more. And now our database designer taking meetings with programmer and explaining the things was older database. so programmer have to find excessive work written on the code.  and replace with just simple modification made by our DB designer.

First Important thing needed is to first convert required tables into innodb

alter table books engine = 'innodb';
alter table purchasers engine = 'innodb' ;

Then Adding of foreign keys.

alter table purchasers add foreign key (bookid) references books(id) on delete cascade on update cascade ;

Doing This will add foreign key so that when we delete any book it will delete all their respective references given on purchasers table. which can be achieved with only single sql execute in php see the following line.

delete from books where id = _NUMBER_

some time we have seen that we have to drop foreign keys. and mysql manual says that use the following syntax.

alter table tableName drop foreign key keyName ;

But now the problem is that how to get that key name.  Then you need to use following way.

show create table tableName;

Doing this you will get name of foreign key. then delete the foreign key and index key.  Please note that when you want to add foreign key to any table try to make foreign key symbol name by your own rather than automated by mysql. This will easier for you manage and maintaining the all the keys. every foreign key comes with 2 kays one foreign key and one index key. if you just delete only foreign key then it will not be good way. as you are keeping garbage of index kay.

I told my friend that I generally charge 12 - 14$ per hour per man. He just shocked to hear my words. Saying me that this is one of the cheapest rate in US. As this charges are for unskilled labour over their. I said, I agree on this. but thats the reason you will save cost while transfering(outsouceing) work to us.

Many people thinks that if we are charging less means that we are not giving the quality. But Who told that quality having any relation with cost. Basically we keep our expenses very tight. We try to avoid extra cost which required for running business. As far as the quality is concern all our customers are satisfied with our quality. and they are still happy to give more work to us.

Its all depends how many work head your project requires. If something is giving less in cost then why to spend more money on expensive things.

Now things started making complicated. I have suggested him to doc one short domain but later realize that he doesn’t have option to part domain for their hosting. so I have been told to use API for which will programmatically convert long url into short url.  so I have  added this blog so that people will understand how to create program which will dynamically covert long url into shorter one.

All the methods which I have suggested based on php programming.

Requirement :

I have used some of higher php function for that it needs you have 5.2.0+ and JSON is integrated. and Curl option is enable for your domain.

There has been 2 sites which we are working on http://cli.gs and http://bit.ly now you have registered their site. I hope they are still free and get Key as basically these are the keys which want while processing.

cli.gs

For This site you need to understand POST is not accepted by cligs. so you have to send data in get method.

<?php

$key = "abe34849f398d02b83abf64ed6690ef5a"; // This will be your key
$tobeShorten = "http://www.runwalsoft.com/blog/index.php";
// This will be url which you want to make it short
$url = "http://cli.gs/api/v1/cligs/create";
$param = "url=". urlencode($tobeShorten) ."&title=This is testing&key={$key}&appid=RunBlog";
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url . "?" . $param);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$result = curl_exec($ch);
// Look at the returned header
$resultArray = curl_getinfo($ch);
curl_close($ch);

if($resultArray['http_code'] == 200)
{
  // This means that key is correct and the url which you have given is also working.
  echo "Short url is <b>" . $result . "</b>";
}
else
{
  echo "Error occured " . $resultArray['http_code'] ;
}

?>

Note : here key which I have written is dummy key. where you have to copy paste the key which you got from the site. and see you will get short url

Bit.ly

For Bit.ly there are few advantages and few are disadvantages. we can create 5 links concurently from same IP address. though that is really rare condition. advantage is that you can process multiple links at the same time. Means let say you want to convert 4 links in just one CURL call then it will be possible. and here you can use POST as well as GET mothod.

In both site you need to understand we have taken care of response from the server. if we got response header as 200 ( which means OK) then everything moving on is preety good. by default bit.ly provides response in JSON. I hope you know that thing. if you don’t know much just visit here its one of the simple method to process.

There is another option as well to process reponse as xml but I also still feel better to use JSON.

<?

$key = "R_c02b4ad85ccdsde92asdfe3951dfac08";
$username = "mrunwal" ;  // This is username when you register on their site.
$tobeShorten = "http://www.runwalsoft.com/blog/index.php";
$url = "http://api.bit.ly/shorten";

$param = "url=". urlencode($tobeShorten) ."&title=This is testing&key={$key}&appid=RunBlog";
$param = "version=2.0.1&longUrl=". urlencode($tobeShorten) ."&login=". $username ."&apiKey=" . $key ;

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url . "?" . $param);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$result = curl_exec($ch);
// Look at the returned header
$resultArray = curl_getinfo($ch);
curl_close($ch);

//Following is the method to handle json output

//This function REQUIRES you should have php5.2.0 +
$result = json_decode($result,TRUE);

// This is the response which you gets from curl
/* "errorCode": 0, "errorMessage": "", "results": { "http://www.runwalsoft.com/blog/index.php":
{ "hash": "ptlxO", "shortKeywordUrl": "", "shortUrl": "http://bit.ly/11vL1X", "userHash": "11vL1X" } },
"statusCode": "OK" */

if($resultArray['http_code'] == 200 && $result['errorCode'] == 0 && $result['statusCode'] == "OK")
{
  // This means that key is correct and the url which you have given is also working.
  echo "Short url is <b>" . $result['results'][$tobeShorten]['shortUrl'] . "</b>";
}
else
{
  echo "Error occured " . $resultArray['http_code'] ;
}

?>

Using this way it will be easier for you to process all shortenning of url. I hope you will feel better to use Runwalsoft’s programming for your current project. don’t botter to contact us.

Requirement : This is really Big in their requirement. I know most of the multilevel marketting peoples really like to see this work. or even like to purchase similar software.  Let say there are some 50 forms which will be dispatched by admin and so they don’t have any sponsor. and each form will given to 50 person. and Once payment is received then each person we will deliver 4 forms.  In short in long run each person will have only and only 4 forms.

For Every member you have there is specific time [we called expiry] they have to sold their 4 forms. and once their 4 forms is sold then some sort of commission + gift will be given by owner.

…there are even more detail… stay tuned. wann visit site http://www.parasmanisuitings.com

if you want to create similar web site then we will arrage some demo of existing work so that you will get confidence and can able to see backend(back office work). This will helps you to manage your contents. Thats the benefits of Runwalsoft’s programming efforts.

As any how we need to support that customer. though this part is their major problem and never like my customer in trouble. I told them that we need to upgrade

• Mysql server
• Installed Memcache module
• Grant user for creating procedures, trigger, functions.

As server company was belong to his friend. and he is quite friendly with me as well. so upgraded the module. thought memcache need to add some part in our programming. this make that site even super fast. and load on the server was drastically reduced. as most of queries(lots of sql statement) are being executed in cache parts so its very obvious that program will be move faster.

Previous version belongs table structure. and new version of the site itself tableless structure so html pages are moving even more faster. This is the work which I really happy to deliver bcz lots of things working as per my expection. There is another project “parasmani suiting” for that I had contacted Indiatimes’s hosting panel but their staff are one the fool peoples. They have upgraded mysql to mysql5.0 but doesn’t provided permission to user for creating procedures , trigger or function. so I unable to provide advance features to my customer. Here in this case, hosting guys are really smart enough to understand technologies and ready to move for advance versions.

In this project we have used sprits as well. to understand sprite keep in touch with this blog. This whole work is carried out in smarty template engines. It looks that I fall in love with smarty.

This is how their new site looks like.

New Theme for Ahvideoz

when ahvideoz saw this site then he is also happy to give his more work to runwalsoft. and thats what I called goodwill for me. There are some minor changes on the site and then we will move another work for this customer.

So first we have shown him 5 template.  from which he likes 2 different things. some part of  first theme and some part of another theme. and our best designer have make such a fabulous themes and logo for them. which customer hardly objected. Work is started with daily updation and chatting with him, and we decided to move forward with smarty tempalte system. though my friend don’t know about net technologies but he trust me so much and given me full authority on technologies.

When work is on completion he decided to add few more points which was not the part of theme. but I also thought that he is saying correct. as majority of theme looks little white color. so later added few more designing things and great flash created by designer. and finally site looks like this. www.printitindia.com

PrintItIndia's Theme

when we tried to upload the site then found that there hosting was free hosting on godaddy. and godaddy having some extra code for free sites. They generally add extra Advertise on free site. but that advertise doesn’t look good on the site. which we really need to stop that. so we added one css coding which makes site really working good.

Customer also want that their product need to driven from admin panel. and they are displayed on index page with small scrolling between the product. so as per their expection we have finally deliver work in just 1 week. and he is so happy that I can not express in words.

Most of the time what we design is much important. because if design is wrong then it will affect the performance of the site. let see following points step by step.

• Database
• Image Creation
• HTML Pages
• CSS Handling
• Cache Utilization
• Hardware related things [ This things belongs to hosting company so it will not be explain]

I will explain each points with you in short time.  stay tune.

when we started working on php and mysql then only mysql module was provided and different hosting company even not updated their mysql for latest version. so specifically we had to use the old technique to access these things. now many things are changing.  People at the server company realize that they need to keep updated servers then only they will get more customer for their hostings. and now a days even customer are already known abt pros and cons of databases.

Now things begins here.  now you have old traditional web site which was created using old techniques and you want to make things more optimised and go with new cutting edge technologies. so there few things which you really need to keep in mind that now a days different layers are used for web sites. its not as easy as what traditional methods.  now on every front peoples are getting more advance. just for the sake of example. now for handling database there are dedicated peoples who knows clustering , memorycache ing for mysql. and in designing now advance flash version details are used with greate features. some templating used to keep site flexible to modify. and here we(Runwalsoft) have made all front details advance. each of our designer, programmer, database handlers are advance. they know how to tacles the hits. and how to mange more hits without losing their customers.

just for the sake of programmer. let say if you have used to open database connection you might have used.

$cn = mysql_connect('localhost','root','password') or die ('Unable to connect' . mysql_error());

which now you have to change like this.

$cn = new MySQLi('localhost','root','password','DatabaseName') or die("Unable to connect");

in the similar fashion you have to change queries as well previously we was using

$rs = mysql_query($sql,$cn) or die("Unable to find sql statement<br>" . mysql_error());

which is now

$rs = $mysqli->query($cn, $sql) or die("Unable to find sql statement <br>" . $mysqli->error);

I know that this is very very simple things but sometime people forgot how to use these.  so I am writting this for newbie. mysqli means that mysql improved. and it having my good features along with it. I will update few more lines after some time. lets have start atleast.

Old Design

Education and More Site Old Design

New Design

Education and more site with new design

Major changes which we have delivered. we have given them paypal integration. with customized puzzles created for them. even admin can approve and disapprove puzzles created by customers.

As they already had admin panel so we have appended new things for them such as managing newletters. and setting letters to subscribers with html formats.
