Make an array key a variable

Is there a way to do this with a multidimensional array?

Example array:
Array
(
[0] => Array
(
[cat_no] => 1033
[desc] => D-Link DP-300U
[price_to_cust] => 100.00
[in_stock] => 12
[ordered] => 1
)

[1] => Array
(
[cat_no] => 1017
[desc] => PSC QS 6000 Plus
[price_to_cust] => 325.00
[in_stock] => 0
[ordered] => 1
)

)

	foreach($inv as $item_num){
		if($_POST['ordered' . $item_num]){
			//echo $_POST['ordered' . $item_num] . '<br>';
			$item_num['ordered'] = $_POST['ordered' . $item_num];
		};
		if('yes' == $_POST['delete' . $item_num]){
				//echo 'delete' . $item_num;
			unset($item_num);
		};?>
		<tr>
			<td><?php echo $item_num['desc'] ?></td>
			<td><?php echo $item_num['price_to_cust'] ?></td>
			<td><?php echo $item_num['in_stock'] ?></td>
			<td><input type="text" size="2" name="<?php echo 'ordered' . $item_num?>" value="<?php echo $item_num['ordered']?>"></td>
			<td><input type="checkbox" name="<?php echo 'delete' . $item_num?>" value="yes"></td>
		</tr><?php
	};

You can see what i'm trying to do.. but when i echo $item_num it gives me array, which I am assuming is the entire array.

 

Hi

The problem is that you are referencing the multi-dimensional array as if it were single dimensional.. You need to reference the data like this:

echo $item_num[ 0 ]['desc'];
echo $item_num[ 0 ]['price_to_cust'];
echo $item_num[ 0 ]['in_stock'];

echo $item_num[ 1 ]['desc'];
echo $item_num[ 1 ]['price_to_cust'];
echo $item_num[ 1 ]['in_stock'];

echo $item_num[ 2 ]['desc'];
echo $item_num[ 2 ]['price_to_cust'];
echo $item_num[ 2 ]['in_stock'];

PHP:

Brew

 

The problem with that is that there could be more items in the cart than that, and I would have to have a variable that has the number in it, correct?

 

Use sizeof() to determine how big the array is. Try this:

for ( $count = 0 ; $count <= sizeof( $item_num ) ; $count++ )
{
echo $item_num[ $count ]['desc'];
echo $item_num[ $count ]['price_to_cust'];
echo $item_num[ $count ]['in_stock'];
}

PHP:

Brew

 

That is what i had done originally, only with count(). The problem with that was that if I wanted to delete an item, the array would have key's 0,1,3 for example and then it wouldn't show right in the table. Any other ideas?

 

foreach (array_keys($item_num) AS $key)
{
    echo $item_num[$key]['desc'];
}
