[SOLVED] displaying array stored in a session from external page

[emtec]

i'm trying to transfer an array from one page to an other one, in a session

 

array /session:

<?php
$_SESSION['info'] = array();

 

array echo:

<?php
//check if info box  needs to be showen
if (!empty($_SESSION['info'])){
echo "<div class='info_message'>";
$nr = count($_SESSION['info']);
for ($row = 0; $row < $nr; $row++)
{   
   echo"<p><img src='images/icons/".$_SESSION['info'][$row]['icon']."' width='16' height='16' /> ".$_SESSION['info'][$row]['text']."</p>";
}
//close info box
echo "</div><!-- end info_message -->";
unset($_SESSION['info']); }

 

storing array in session on an other page:

<?php array_push($_SESSION['info'], array (icon => "add.png",text => ADMINADDINFO ));

 

i just get an empty session, if i copy the array push on the same page, it will work.

can any1 tell me what i'm doing wrong?

need to put

 

session_start();

 

before you can use session vars (on any page you use them, not just where you assign something to them).  It also needs to come before any output, even blank spaces or lines.

[emtec]

yeah done that on both pages

[.josh]

did you declare $_SESSION['info'] as an array, before trying to array_push something into it?

 

edit: yes you did.  Sorry, kind of hard to tell, when you have your code all broken up and out of order like that.  Repost the code together and in order, please.

[emtec]

i will post some more info, maby there is something wrong with somthing else

 

index.php

<?php
session_start();
$_SESSION['info'] = array();

//some other code

include('inc/infoboxes.php');

//some other code

 

inc/infoboxes.php

<?php
//check if info box  needs to be showen
if (!empty($_SESSION['info'])){
echo "<div class='info_message'>";
$nr = count($_SESSION['info']);
for ($row = 0; $row < $nr; $row++)
{   
   echo"<p><img src='images/icons/".$_SESSION['info'][$row]['icon']."' width='16' height='16' /> ".$_SESSION['info'][$row]['text']."</p>";
}
//close info box
echo "</div><!-- end info_message -->";
unset($_SESSION['info']); }
?>

 

external page

<?php
session_start();

// some other code

array_push($_SESSION['info'], array (icon => "add.png",text => ADMINADDINFO ));

[.josh]

You initialize $_SESSION['info'] and then turn around and then include infoboxes.php.  You didn't actually assign anything to $_SESSION['info'] before the include.  What is that external page?  The code in "external page" needs to happen somewhere before the include in your index.php

 

 

[emtec]

on the extrenale page you get redirected to the index.php after assigning the array

[.josh]

Okay, so let me get this straight: your coding order is this? (look at the comments I added):

 

index.php

<?php
session_start();
$_SESSION['info'] = array();

//some other code
// CALL EXTERNAL PAGE HERE

include('inc/infoboxes.php');

//some other code

 

external page

<?php
session_start();

// some other code

array_push($_SESSION['info'], array (icon => "add.png",text => ADMINADDINFO ));

// REDIRECT TO INDEX.PHP

 

 

[emtec]

no the exernal page isnt included in the index.php, its accessed by submitting a form.

then that external file adds in the array and then redirects back to index.php

[.josh]

Okay well then it sounds like your index.php is overwriting the array_push with

 

$_SESSION['info'] = array();

[emtec]

hmm ok, is there any way how i can resolve this?

[.josh]

Well, I'm still kind of confused about your program flow... but it sounds like if you put that session var init in your external page, that should do the trick.

[emtec]

ok that was the problem thx a lot m8

 

i solved it this way

<?php
//declare arrays
if (!isset($_SESSION['info'])) {
$_SESSION['info'] = array();
}

[.josh]

ah, yeah, guess that would have the same effect.
