Question

I have a form with input fields like:

post_1a ; post_1b ; post_1c

post_2a ; post_2a ; post_2a

post_3a ; post_3a ; post_3a

<table>
    <tbody>
        <tr>
            <td><input id="new_post_a" name="post_1a" type="text"></td>
            <td><input id="new_post_b" name="post_1b" type="text"></td>
            <td><input id="new_post_c" name="post_1c" type="text"></td>
            <td><button id="add_row_btn">Toevoegen</button></td>
        </tr>
    </tbody>
</table>

i want to catch with the post, but because this field are generate with javascript, i have tried to catch with preg_match/explode but results, i need the value of the input.

I cannot change the input name’s because of the javascript.

does somebody has an idea becuase i have no ideas anymore?

How about this:

// start with post_1a
$i = 1;

// while post_{$i}a (and ...b and ...c) is set, do ...
while (isset($_POST["post_".$i."a"], $_POST["post_".$i."b"], 
    $_POST["post_".$i."c"]))
{
    // do something useful with the three values
    var_dump(
        $_POST["post_".$i."a"], 
        $_POST["post_".$i."b"], 
        $_POST["post_".$i."c"]
    );

    // increment $i for the next 3 inputs.
    $i++;
}

If you can change the input’s names, see this article for a cleaner solution.
