Storing variables in a session

[denhamd2]

Hi,

 

I'm wondering could you help me... I'm sending a number of variables between 2 pages using the form GET method, and I want to store them in a session. The variables are basically called after dates and they will equal "yes" if the user has selected them.

 

Eg. they might have selected 3 tickboxes in page 1:

 

$07042007 = yes

$18042007 = yes

$22042007 = yes

 

which get sent to page 2 via the URL

 

is there any way of storing these in session variables of the same names?

First, you can't have variable names that start with a digit in PHP, so those are illegal.

 

To store a value in a $_SESSION, do

<?php
$var = 'yes';
$_SESSION['var'] = $var;
?>

I'm going to have a number of variables coming into the 2nd page, sometimes it might be 2 variables, other times it might be 17 variables, so is there any way I can store all the variables passed as session variables dynamically?

This will set all your get varibles to session with same name in get

 

if(isset($_GET)){

        foreach($_GET as $key => $value){

                $_SESSION[$key] = $value;

          }

}

great thanks is there any way I can echo all my session variable $value's then on the 2nd page (separated by <br> tags)?

[jitesh]

if(isset($_GET)){
         foreach($_GET as $key => $value){
                $_SESSION[$key] = $value;
          }
}

echo "<pre>";
print_r($_SESSION);

foreach($_SESSION as $key => $value){
.........................
..........................

I think you will get this
}

Edit: figured it out just echoed the $value, easy!

 

Only thing is it echos the value of the submit button from the first page, the name of this is monthsubmit, and the value is bookdays... any ideas on not having this stored as a session variable?

[jitesh]

Explain what you need to do after storing get data into session ?

[denhamd2]

sorry mate just edited my above message, any ideas on that?

[jitesh]

list out the varibles you do not want to set in session of previous page which are fixed and few. like this

 

$un_nec_varible = array('monthsubmit','anyother');

if(isset($_GET)){
         foreach($_GET as $key => $value){
               if(!in_array($un_nec_varible,$key)){ 
                      $_SESSION["DATA"][$key] = $value;
               }
         }
}
echo "<pre>";
print_r($_SESSION["DATA"]);

[denhamd2]

getting the error msg for each of the variables:

 

Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/aholiday/public_html/calendar/index2.php on line 9

[jitesh]

if(!in_array($key,$un_nec_varible)){

[denhamd2]

something strange happens, it just echos the word Array

 

any ideas?

 

 

[jitesh]

print_r is used to print array and object.

 

echo "<pre>";
print_r($_SESSION["DATA"]);
