Question

I have a form, where I submit the data to $_POST['foldername']

createdir.php below

<form action="mkdir.php">
    <input type="textarea" name="foldername" id="foldername">
    <input type="submit" value="Create directory">
</form>

Then I have mkdir() that should have a path including the name got from a input field, but the problem is, that it doesn’t get the data from input. I tried to print it as well, but all I get is /images/ but I should (at least I hope to) get /images/nameFromInput.

mkdir.php below

<?php
$foldername = $_POST['foldername'];

$path = 'images/' . $foldername;
mkdir($path);
header('Location:createdir.php')
?> 

Where’s the problem?

Answer 1

<form action="mkdir.php" method="POST">

You forgot the method.
