Arrays unset

[Brusca]

Hi Guys,
I have a small issue with the unset of a multidimensional array.

$bob = array(
array('quantity' => 2, 'product' => 302),
array('quantity' => 1, 'product' => 202),
array('quantity' => 1, 'product' => 134),)

I have no problem with displaying the elements of ech value within $bob with the "for each". I have a form button created with each element in order to delete/unset that particualr array in $bob.
When the delete button is pressed I can't seem to be able to correctly identify $bob[????] to delete. Which results in the incorrect array being deleted within $bob.

Is there a fool proof way of identifying the $bob[number] when looping through the array?? Can you use the 'product' value to identify the correct array??

Cheers for your help

Sure...

foreach($bob as $key => $value) {
  // your button with value of delete[$key]
}

That sets it up as an array, so from there, all you need to do on theunset page is

foreach($_POST['delete'] as $key) {
   unset($bob[$key]);
}

I must be getting a lil bit confused. I can't seem to get that to work.
Maybe if I could re-index the array after deleting one of them that would solve my troubles. As once one is deleted it seems to be leaving the index there but with no value.

when outputting my array values with html with my for each loop I am incrementing $i to match $bob[$i] but once one is deleted they no longer match. Can I re-index or use array_splice.

Cheers

You could reindex...
