Question

Thank you for looking at and taking time to answer my question!

I would like to use a multi-dimensional array in a form on my site and then access it using the keys; Like so.

<form method="post" action="somescript.php">
    <input type="text" name="name[1][title]">
    <input type="text" name="name[1][descritpion]">
</form>

I would then like to access both the index, since that is the ID, and the value of the given _post’ed element. Something like

$keys = array_keys($_POST['name']);
 foreach($keys as $id)
 {
      echo "title: " . $_POST['name']['title'][$id];
      echo "description: " . $_POST['name']['description'][$id];
      echo "id: " . $id;
 }

Now, the above looks nice and it prints out the correct $id but thats about it. I assume I am putting the “title” or “description” array calls in the wrong place but cannot figure it out. Could someone kindly point me in the right direction?

Answer 1

In your PHP, you are looking for $_POST['name']['title'][$id], but in your HTML you have name[1][title].

These are not the same array. You either need to change the HTML to name[title][1], or the PHP to $_POST['name'][$id]['title'].

It doesn’t matter which you use, just be consistent, though I suggest using name[title][1] as that may be easier to work with.
