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] => ) )

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['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><form action="">
<button type="submit" class="btn btn-default" name="btnSubmit2">Delete Line</button>
</form></td>
</tr>
<?php ;} //End of while ?>
</table>
<div class="row">
<div class="col-sm-6 text-center">

<?php if(isset($_GET['btnSubmit2'])) {
unset($_SESSION['cart'][$key]);
};?>
