Question

I am using a form to create several arrays in a Session. Each time the form is submitted a new $_SESSION[‘item’][] is made containing each new array. The code for this:

$newitem = array (
    'id' => $row_getshoppingcart['id'] ,
    'icon' => $row_getimages['icon'],
    'title' => $row_getimages['title'],
    'medium' => $row_getshoppingcart['medium'],
    'size' => $row_getshoppingcart['size'],
    'price' => $row_getshoppingcart['price'],
    'shipping' => $row_getshoppingcart['shipping']);

$_SESSION['item'][] = $newitem;

There could be any number of item arrays based on how many times the user submits the form. Any ideas how can I get the value of the array key that is being put in place of the [] in the session variable? I am trying to create a remove from cart option and cannot figure out how to reference that particular array in the session to unset it.

I am currently displaying the items as such:

<?php foreach ( $_SESSION['item'] AS $item )
echo $item['title'];
echo $item['icon'];

and so on…

Thank you in advance for your time. I really appreciate it.

Answer 1

foreach($_SESSION['item'] as $key => $value) will enable you to seperate the key and value, and ofcourse, to access the value current key has.

To extend this with an example, consider following code:

<?php
$exArray = array("foo"=>"bar", "foo2"=>"bar2);

foreach($exArray as $arrKey => $arrValue):
    echo "The key ".$arrKey." has the value of ".$arrValue."<br />\n";
endforeach;
?>

will output:

The key foo has the value of bar.

The key foo2 has the value of bar2.

However, in the same way, if the $arrValue variable is known to hold an array, it will keep it’s content. To loop through that second array, you will need to loop it through another foreach statement.
