Create a Dynamtic $_SESSION variable name (by incremental number)

[TurtleInAsia]

Hi,

 

I am trying to improve my old code that controls a shopping list, so that instead of having lots of code it loops until the end is detected. Can someone help me out :-)

 

I have a list of 5 session variables like this:

 

$_SESSION['List']['1']['Title']

$_SESSION['List']['2']['Title']

$_SESSION['List']['3']['Title]

$_SESSION['List']['4']['Title']

$_SESSION['List']['5']['Title']

 

What I currently do is a if else statement like this

 

if (!isset($_SESSION['List']['1']['Title'])) { $_SESSION['List']['1']['Title'] = $_POST['title']; }

elseif (!isset($_SESSION['List']['2']['Title'])) { $_SESSION['List']['2']['Title'] = $_POST['title']; }

elseif (!isset($_SESSION['List']['3']['Title'])) { $_SESSION['List']['3']['Title'] = $_POST['title']; }

elseif (!isset($_SESSION['List']['4']['Title'])) { $_SESSION['List']['4']['Title'] = $_POST['title']; }

elseif (!isset($_SESSION['List']['5']['Title'])) { $_SESSION['List']['5']['Title'] = $_POST['title']; }

 

However this is not good because it is hard coded to a limit of 5.

 

What i want to do it a method of automatically incrementing the number and looping until the number is empty, which will also allow me to have more than 5 entries.

 

Hope that makes sense, any help greatly appreciated :-)

It doesn't really make much sense considering your storing the same data ($_POST['title']).

[mikesta707]

that doesnt really loop? wouldnt you want something like

 

$i = 0;
while ($i < /* whatever your limit is */ ){
$_SESSION['List'][i]['Title'] = $_POST['title'];
i++;
}

 

Or is that what you had before and what you want to change it from?

[TurtleInAsia]

Yes sorry that is my old code I would like to change.

 

I see your new code recommendation and it looks much easier to work with, is there a way to not specify the end number but stop if it reaches a value that is not set ?

 

I am going to try a few things out and will update my results here. Thanks again for the example.

$i = 0;
$count = count($_SESSION['List']);
while ($i < $count ){
$_SESSION['List'][$i]['Title'] = $_POST['title'];
i++;
}

Something like that?

[kenrbnsn]

That's basically a "for" loop

<?php
$count = count($_SESSION['List']);
for ($i=0;$i<$count;$i++)
   $_SESSION['List'][$i]['Title'] = $_POST['title'];
?>
