Reference key in foreach loop
On line 45 I need to put the code in to unset the item in the table list. How do I reference the key for that item?
Here are the results from the print_r on line 21:
<?php
$size = $_GET["size"];
$color = $_GET["color"];
$style = $_GET["style"];
$qty = $_GET["qty"];
$cat = $_GET["cat"];
$sub = $_GET["sub"];
$thumb = $_GET["thumb"];
$cart = array(
'size' => $size,
'color' => $color,
'style' => $style,
'cat' => $cat,
'sub' => $sub,
'thumb' => $thumb,
'qty' => $qty
);
$_SESSION['cart'][] = $cart;
print_r($_SESSION['cart']);
?>
<br><br>
<h2 class="required">Quote Cart</h2>
<table class="table table-bordered table-condensed table-striped table-responsive">
<tr class="table-header">
<td><b>Image</b></td>
<td><b>Style</b></td>
<td><b>Color</b></td>
<td><b>Size</b></td>
<td><b>Quantity</b></td>
<td><b>Order More</b></td>
<td><b>Delete</b></td>
</tr>
<?php
foreach ($_SESSION['cart'] as $item) {;?>
<tr>
<td><img src="/SDL/THUMBNAIL_IMAGE/<?php echo $item['thumb'];?>" alt=""></td>
<td><?php echo $item['style'];?></td>
<td><?php echo $item['color'];?></td>
<td><?php echo $item['size'];?></td>
<td><?php echo $item['qty'];?></td>
<td><a href="prod_detail2.php?style=<?php echo $item['style'];?>&sub=<?php echo $item['sub'];?>&cat=<?php echo $item['cat'];?>&btnSubmit=save">Add More</td>
<td>Delete</td>
</tr>
<?php ;} //End of while ?>
</table>
Here are the results from the print_r on line 21:
Array ( [0] => Array ( [size] => M [color] => Maroon [style] => ST215 [cat] => Activewear [sub] => Baseball [thumb] => ST215TN.jpg [qty] => 10 ) [1] => Array ( [size] => 2XL [color] => Black [style] => ST215 [cat] => Activewear [sub] => Baseball [thumb] => ST215TN.jpg [qty] => 10 ) [2] => Array ( [size] => S/M [color] => Black [style] => A705 [cat] => Accessories [sub] => Aprons [thumb] => A705TN.jpg [qty] => ) [3] => Array ( [size] => S/M [color] => Black [style] => A705 [cat] => Accessories [sub] => Aprons [thumb] => A705TN.jpg [qty] => ) )

If I understand the question correctly... You can change your foreach iterator to get the key. Example:
foreach ($_SESSION['cart'] as $key => $item)
Then you can unset($_SESSION['cart'][$key]);
foreach ($_SESSION['cart'] as $key => $item)
Then you can unset($_SESSION['cart'][$key]);
You can also access the array value by adding increment varriable
<?php
$i=0;
foreach ($_SESSION['cart'] as $item) {
echo '<pre>'; print_r($_SESSION['cart'][$i]); echo '</pre>';//ACCESS VALUES USING $i
?>
<tr>
<td><img src="/SDL/THUMBNAIL_IMAGE/<?php echo $item['thumb'];?>" alt=""></td>
<td><?php echo $item['style'];?></td>
<td><?php echo $item['color'];?></td>
<td><?php echo $item['size'];?></td>
<td><?php echo $item['qty'];?></td>
<td><a href="prod_detail2.php?style=<?php echo $item['style'];?>&sub=<?php echo $item['sub'];?>&cat=<?php echo $item['cat'];?>&btnSubmit=save">Add More</td>
<td>Delete</td>
</tr>
<?php $i++; } //End of while ?>
</table>
Apparently I am not coding it correctly. It works but always deletes the last key, not the one from the table row.
<table class="table table-bordered table-condensed table-striped table-responsive">
<tr class="table-header">
<td><b>Image</b></td>
<td><b>Style</b></td>
<td><b>Color</b></td>
<td><b>Size</b></td>
<td><b>Quantity</b></td>
<td><b>Order More</b></td>
<td><b>Delete</b></td>
</tr>
<?php
foreach ($_SESSION['cart'] as $key => $item) {;?>
<tr>
<td><img src="/SDL/THUMBNAIL_IMAGE/<?php echo $item['thumb'];?>" alt=""></td>
<td><?php echo $item['style'];?></td>
<td><?php echo $item['color'];?></td>

<td><?php echo $item['qty'];?></td>
<td><a href="prod_detail2.php?style=<?php echo $item['style'];?>&sub=<?php echo $item['sub'];?>&cat=<?php echo $item['cat'];?>&btnSubmit=save">Add More</td>
<td><form action="">
<button type="submit" class="btn btn-default" name="btnSubmit2">Delete Line</button>
</form></td>
</tr>
<?php ;} //End of while ?>

You are not sending the $key value anywhere - you need to put it in your form so that when the button is clicked you can send the value back to the server
Something like this (this is not how I would do it but this is how to do it given the code you have submitted)

<?php

if(isset($_GET['btnSubmit2'])) {
$key = isset($_GET['id']) ? $_GET['id'] : false;
if ($key) {
unset($_SESSION['cart'][$key]);
}
// WHEN YOU GET HERE ITEM HAS BEEN DELETED SO CONTINUE WITH YOUR RENDER
