read multiple variables with same name

[bulevardi]

If you have a form with some fields like textareas etc:

<p><label for="paragraph">Paragraph: </label><textarea name="paragraph" id="paragraph"></textarea></p>

... and you have a javascript that lets you add inputfields and textareas (with the same name and id's) when you click on a link to make that happen,

Is there a possibility in php to read that form out with those new javascript created formfields, like:

$paragraph = $_POST['paragraph'] ;

So if you create more than one paragraph with the same id's and names, how can you do that?
Is it possible with something like that?

$amountPar = count('$_POST['paragraph']');
for(i=0; i<$amountPar; i++){
$paragraph[i] = $_POST['paragraph'];
}

lets use array names in your textarea name tag:

<textarea name="paragraph[]"

And in processing program:

<?php
if ( isset( $_POST["paragraph"] ) AND count( $_POST["paragraph"] > 0 ) ) {
    foreach( $_POST["paragraph"] AS $paragraph )
    echo $paragraph . "<br />";
} 

?>

If you end the HTML form name with [] then PHP will allow you to access them using array notation.

Idendifiers must be unique though, so you will need to ensure that those don't repeat.

<p>
    <label for="paragraph1">Paragraph: </label>
    <textarea name="paragraph[]" id="paragraph1"></textarea>
</p>

$paragraph = $_POST['paragraph'];
// because form was "paragraph[]", $paragraph is now an array

Hmm, not possible in my case. My php script won't know beforehand what the names of my identifiers will be. Well, only just one name for that variable. So I'll try to make that with an array aswell.
I'll try it this evening. Thanks!

one name, but that could be an array variable name. using the [] 's
