[RESOLVED] Remove row from array (if...)

[_s_]

I have a multidimensional array with 3 columns, and a number of rows. Some of these rows have a field/value returning $row['value'][$i] == on (from a form checkbox field).

$product_arr = array(); 
foreach ($_POST['sent'] as $i=>$value) {
    $product_arr[$i]['quantity'] = $value; 
    $product_arr[$i]['name'] = $_POST['name'][$value]; 
    $product_arr[$i]['price'] = $_POST['price'][$value];
}

If I have four rows with $_POST['sent'] turned on, I will be left with an array with only four rows, even though the array originally has 10 rows. However, I am left with the first four rows, not the distinct four rows that I would like to process.

If anyone can offer suggestions to how I can remove the entire row if it has a $_POST['sent'] in it, I would be grateful!

what does your form look like?

Here's the form - the value for sent[] is the unique identifier for the item, and is what I'm using to determine whether I should remove the row or not.

<form name="status" action="update.php" method="post">

<input type="hidden" value="2" name="quantity[]" />
<input type="hidden" value="Product name" name="name[]" />
<input type="hidden" value="42.00" name="price[]" />
<label>Send? <input type="checkbox" value="90042" name="sent[]" /></label>

<input type="hidden" value="1" name="quantity[]" />
<input type="hidden" value="Product name" name="name[]" />
<input type="hidden" value="50.00" name="price[]" />
<label>Send? <input type="checkbox" value="90002" name="sent[]" /></label>

<input type="hidden" value="1" name="quantity[]" />
<input type="hidden" value="Product name" name="name[]" />
<input type="hidden" value="86.00" name="price[]" />
<label>Send? <input type="checkbox" value="70445" name="sent[]" /></label>

</form>

So when two of the checkboxes are checked, I still get an array containing four rows, but I only want to process the rows where the checkbox is checked.

Any hints appreciated!

i suggest your re-organize the incoming POST data differently:

<form name="status" action="" method="post">

<input type="hidden" value="2" name="data[90042][quantity]" />
<input type="hidden" value="Product name" name="data[90042][name]" />
<input type="hidden" value="42.00" name="data[90042][price]" />
<label>Send? <input type="checkbox" value="Y" name="data[90042][sent]" /></label>

<input type="hidden" value="1" name="data[90002][quantity]" />
<input type="hidden" value="Product name" name="data[90002][name]" />
<input type="hidden" value="50.00" name="data[90002][price]" />
<label>Send? <input type="checkbox" value="Y" name="data[90002][sent]" /></label>

<input type="hidden" value="1" name="data[70445][quantity]" />
<input type="hidden" value="Product name" name="data[70445][name]" />
<input type="hidden" value="86.00" name="data[70445][price]" />
<label>Send? <input type="checkbox" value="Y" name="data[70445][sent]" /></label>

<input type="submit" value="submit" name="submit" />
</form>

<?php
if (isset($_POST['submit']))
{
	echo 'the following products were checked:<br><br>';
	foreach ($_POST['data'] as $key => $value)
	{
		if (isset($value['sent']))
		{
			echo $key . '<br>' . 
			$value['quantity'] . '<br>' .
			$value['name'] . '<br>' . 
			$value['price'] . '<br><br>';
		}
	}	
}
?>

Heh - didn't even know I could put a third level field in the input. Thanks. I'll try it out tonight! 🙂

Worked like a charm! Was able to cut a bit of extra coding as well. Thanks devinemke!
