Can I add to an array using sessions?

[Siggles]

Can I add to an array using sessions? Using session_start() and session_register(); on both pages I pass the following in a form:

<input type='submit' name='submit' value='Add to Portfolio'>
<input type='text' name='name[]' value='richard'>
<input type='text' name='name[]' value='stan'>

and display it on page 2.

eg,

foreach ($name as val){
print "$val<br>";
}

How do I go back to page one, change the value's of the textboxes and add to the array on page 2 so that it displays:

richard
stan
derek

Does Sessions allow you to add to an array?

Thanks

Page1:

	<input type='submit' name='submit' value='Add to Portfolio'> 
	<input type='text' name='name[]' value='richard'> 
	<input type='text' name='name[]' value='stan'>

Page2:

	session_start();

if(!isset($_SESSION['name'])) {
	$_SESSION['name'] = array();
}

array_push($_SESSION['name'], $_REQUEST['name']);

foreach($_SESSION['name'] as $key=>$value) {
	echo "$value<br />";
}

Give that a go. It should come out pretty well, unless I'm trippin 😉
You don't need to use session_register() any more, the new versions of php allow you to initialize a session variable without registering it.

Hope that helps,
Matt

$_SESSION['this_array']=array('bob', 'john', 'fred');
$x=count($_SESSION['this_array']);
$_SESSION['this_array'][$x]='tom';
var_dump($_SESSION);

🆒

Matt, I tried yours as your script will work better when all I am passing across is the name of an array. It sorta worked 😉 . Problem is on the result page it displays Array. The reason I know it works though is If i go back to the sumbit page and submit again the restults page displays

Array
Array

What is wrong. Why isn't it displaying the names?

Thanks for your help!

Great News!! I got it working but on a much larger scale. My question was simplified to make it easier for folks to reply. Anyhow my script now looks like this:

Page 1:

<?php
$array = file('../xfile.txt'); //The database
$anything=array_shift($array);
foreach($array as $row) {
$line = explode('","', $row);
print "Name: $line[1]";

<form name='form1' method='post' action='lettings19.php'>
<input type='submit' name='submit' value='Add to Portfolio'>
<input type='hidden' name='name' value='$line[1]'>
</form>

Page 2:

<?php

if(!isset($SESSION['name'])){
$SESSION['name'] = array();
}
array_push($SESSION['name'], $REQUEST['name']);

$hello = file('../xfile.txt');
$anything=array_shift($hello);
foreach($hello as $row) {
$lin = explode('","', $row);

if (in_array($lin[1], $_SESSION['name'])){
print "Name: $line[1] etc etc etc etc

---

This works a treat. Now I have to work out how to delete individual names from the array and delete the whole array.

Thanks for your help!!!
