sessions - point out the error please?

[rakesh.ravindran]

hello guys..i wrote this code!!

and..... its not working!! 

 

<?php

session_register('db_name');

?>

 

 

<?php

 

if(isset($_POST['posted']))

{

$db_name1=$_SESSION['db_name'];--------->error in here??

$link_id=mysql_connect("localhost",root,"");

$result=mysql_query("create database $db_name1");

echo"result is ".$result;--------->checking to see if its working

}

 

else

{

echo"enter database name:

<form method=post action=database.php>

<input type=text name=db_name>

<input type=submit value=submit>

<input type=hidden name=posted>

";

}

 

?>

 

cud neone find whats d prob?

i think the value of database name entered by the user is not getting into db_name1!!

thank u..

Bcoz the value is coming from post in ur form not from session:

 

$db_name1=$_SESSION['db_name'];--------->Worng

 

Try it like this:

$db_name1=$_POST['db_name'];

Can you show us where have you mention session_start(); and where value for session var "db_name" is set?

hey mmarif..

thanks 4 the response!....

what u said is true...

but..sessions used for storing data in d server side persistently?

and we can access it anytime from the global aarray $_SESSION ?

 

if not, then whats d purpose of sessions?  :-\

 

please

explain?

 

 

hi

jithesh..

i havent used  session_start,  because  its  said  its  not  mandatory, and if we use session_register, a SID will be automatically assigned..

and well...i havent initialised its value!...

is that a problem?

// Check you have Privilege to create database

<?php

session_start();

 

if(isset($_POST['posted']))

{

if(isset($_SESSION['db_name']) and !empty($_SESSION['db_name'])){

            $db_name1=$_SESSION['db_name'];

}else{

        echo "Database name not found ";

        exit;

}

$link_id=mysql_connect("localhost",root,"");

$result=mysql_query("create database $db_name1");

echo"result is ".$result;

}
