具有无限字段的表格

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++;
    }
}

Answer 2

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.
