I have the following code:

<form action="" method="post">
 <input type="text" name="text[0]">
 <a id="AddMore">Add more fields</a>
 <input type="submit" value="submit"> 
</form>

The #AddMore adds input elements (with jQuery) where the number iterates. So when you click it once you get:

<form action="" method="post">
 <input type="text" name="text[0]">
 <input type="text" name="text[1]">
 <a id="AddMore">Add more fields</a>
 <input type="submit" value="submit"> 
</form>

When it is submitted, I want to grab the values of the existing inputs and add it to my $message string. I thought of it something like this:

$message = "Text number: 1 contains: " . $_POST['text[0]'] . "rn" // . $extraInput; ???
for ($x = 1; $x < 20; $x++) { // 20 = max number of inputs
 if(isset($_POST['text[$x]']) && $_POST['text[$x]'] != '')
 $extraInput-$x .= "Text number: " . $x + 1 " contains: " . $_POST['text[$x]'] . "rn"; // how to add this to $message?
 else 
 $extraInput-$x .= "";
 

I know my php is not correct, but I put it here anyway so you would understand my intentions better. The right way to use it is what I like to know/learn.

For example, when I click 'Add more fields' twice. I want php to put the following string into $message:

$message = "Text number: 1 contains: " . $_POST['text[0]'] . "rn" . "Text number: 2 contains: " . $_POST['text[1]'] . "rn" . "Text number: 3 contains: " . $_POST['text[2]'] . "rn";

That's what I finally want to mail using:

mail($to,$subject,$message);

If your <input type="text"> have the attribute name as text[0], text[1], etc, in your php code they values are not in $_POST[text[n]], but in $_POST[text][n].

So, you can obtain desired output in this way:

$message = '';
foreach( $_POST['text'] as $key => $val )

 $message .= "Text number: ".($key+1)." contains: $valrn";

Or — if you want skip empty values — in this way:

$message = '';
$index = 1;
foreach( $_POST['text'] as $val )

 if( $val )
 
 $message .= "Text number: ".($index++)." contains: $valrn";
 

Edit: please also note that there is no need to check is $_POST[text][n] if set, because all elements of an array are set, either if they are empty.

Here is a way to do it :

if(0 < sizeof($_POST['text']))

 $message = '<ol>';
 foreach($_POST['text'] as $text)
 
 if(false === empty($text))
 $message .= "<li>".$text."</li>";
 
 $message = '</ol>';
else
 $message = "void";
