Session array - losing data problem

[Harley1979]

Hi,

 

I'm having a problem with losing data for an array I have stored as a session. I need some help here.

 

Here is my code:

 

First page:

 

<?php

echo "

<form action='wholefoods-placeorder.php' method='post'>

<div id='tableContainer'>

<div id='tableContentHead'></div>

<div id='tableContentMain'>";

 

$mysqlCat = mysql_query("SELECT * FROM productCategory");

while($catRow = mysql_fetch_array($mysqlCat)){

$getCat = $catRow['category'];

echo "<h3 class='newfont'>{$getCat}</h3>";

 

$catID = $catRow['id'];

$mysqlProd = mysql_query("SELECT * FROM products WHERE categoryID = '$catID'");

echo "

<table>

<thead>

<tr>

<th class='i'>Product</th>

<th class='ii'>Size</th>

<th class='iii'>Price</th>

<th class='iv'>Qty</th>

</tr>

</thead>";

 

$i = 1;

while($prodRow = mysql_fetch_array($mysqlProd)){

echo "

<tbody>

<tr>

<td>".$prodRow['item']."</td>

<td>".$prodRow['size']."</td>

<td>£".$prodRow['price']."</td>

<td><input type='text' id='qty' name='qty[".$prodRow['id']."]' maxlength='1' size='1' /></td>

<input type='hidden' name='product[".$prodRow['item']."]' value='".$prodRow['item']."'></tr>

</tbody>";

}

 

echo "

<tfoot>

<tr>

<td colspan='4'></td>

</tfoot>

</table>";

}

 

echo "<input type='submit' id='submit' name='submit' value='Next' />

</div>

<div id='tableContentFoot'></div>

</form>"; ?>

 

Second page:

 

// set sessions

$_SESSION['qty'] = $_REQUEST['qty'];

$qty = $_SESSION['qty'];

//$product = $_REQUEST['product'];

 

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

if (isset($qty[$value])) {

echo $value.", ";

}

}

 

It seems to pick it up and write out on screen ok on the second page. It is after that when going to another url that it seems to lose the data.

 

I'm lost, any help would be great

 

Thanks

 

Harley

You need to call session_start() at top of any page using $_SESSION

[Harley1979]

Yes, this has also been done.

 

As I say the session picks up first time round but then on moving to another page the session data is lost. This is specificaly session data containing arrays, all other session data is fine.

Am I right in saying that all you have to do to set a session is to write

session_start()

at the top of your page, and then

$_SESSION['name'] = "Peter";

to assign its value, regardless of wether or not you are holding an array as its value?

[MadTechie]

not 100% correct

 

you need to have

session_start();

before any output to allow you to read or write to $_SESSION's

 

so if your page as $_SESSION in it then

you need to have

session_start();

before any output
