post two dimensional array in php

Question

I'm trying to post and receive a two dimensional array, but I can't get it to work.

Could you guys help me out?

Thanks in advance!

Here is my code:

$items[] = array(
  'pid' => $pid
  , 'qty' => $product_qty
);

<input type="hidden" name="items[]" id="pid" />

foreach ($_POST['items'] as $row) {
  $pid = $row['pid'];
  $product_qty = $row['qty'];
}

Do print_r($_POST); and you see the structure of your array and with which keys you can access it. — Rizier123

Change your code in a way like this:

$items = array('pid' => $pid, 'qty' => $product_qty);
foreach( $items as $key => $val )
{
    echo '<input type="hidden" name="items['.$key.']" value="'.$val.'" id="'.$key.'" />';
}

In your original code, $items[] add a new item to array $items.

Also, HTML doesn't interpret php variables, so your <input name="items[]" will produce $_POST[items][0] with an empty value.

Thanks! but what do i do on the receiving end?

You will receive yr example's expected $POST => $_POST['items']['pid'] etc... Also note that in my example there is id attribute, as per yr code, but the id attribute is not sent with $_POST

The submitting and receiving works but when i remove the brackets after $items the array displays two times the last loop :(

I don't understand. What loop? $items loop or $_POST loop?

the $items loop, sorry i forgot to mention $items[] = array('pid' => $pid, 'qty' => $product_qty); is in a foreach loop

It's as simple as this:

$myarr = array( 'pid' => array($pid), 'qty' => array($product_qty));
