Form With Unlimited Fields - php

Question

I have a form that has an [Add Fields] option making it possible to add virtually unlimited Item Numbers and Descriptions.
These fields are named: item[] and desc[] (brackets for arrays).
My question is, how would I submit this information with PHP and MySQL so that each row (item and description) is submitted as it's own row in the database?
I've tried multiple methods like submitting item[0] and desc[0] together with no avail :(
Thanks for all of your help in advance!
EDIT: Below is what I've been trying to use... (Sorry, not that great with arrays...)
$count = 0
foreach ($_POST['item'] as $item) {
$query = "INSERT INTO items (item, desc) VALUES ('" . $item[$count] . "', '" . $_POST['desc'][$count] . "')";
// Script simplified as it is quite complex.
if ($query_result) {
$count++;
}
}

Answer 1

you can loop through any one of the input field using foreach loop and then access other fields.
foreach($_POST['item'] as $key => $item){
//your code
$desc = $_POST['desc'][$key];
}
EDIT : as per your code script will be like
$count = 0
foreach ($_POST['item'] as $key => $item) {
$query = "INSERT INTO items (item, desc) VALUES ('" . $item . "', '" . $_POST['desc'][$key] . "')";
// Script simplified as it is quite complex.
if ($query_result) {
$count++;
}
}

To further help you out, I might suggest the following.
Name your fields like so:
line[1][item]
line[1][desc]
line[2][item]
line[2][desc]
etc...
Then in PHP the data will make more 'sense' when viewing it:
<?php
$count = 0;
foreach ($_POST['line'] as $line => $vals) {
$item = $vals['item']; /* do some kind of input validation here */
$desc = $vals['desc']; /* do some kind of input validation here */
/* if no errors, continue */
$sql = "INSERT INTO `items` (`item`,`desc`) VALUES ('$item', '$desc')";
if (mysql_query ($sql)) {
$count++;
}
}
?>
I find this method to be more flexible. Just my two cents.
