and its with not whith my code checking script= CODE <?php $file = '$CHECK'; if (file_exists($file)) { echo "The file $filename exists"; } else { echo "The file $filename does not exist"; } ?> my question is how to check the file whith html example:on a page a text box is provided and a button the user writes a file name (or website) the user clicks on the submit button then it checks and show it (with the code above) i got the code CODE <?php $filename=$_POST['check']; if (file_exists($filename)) { echo "The file $filename exists"; } else { echo "The file $filename does not exist"; } ?> <form method="post"> <input name="check"> <input type="submit" /> </form> but...... the problem is , it will first show $_POST['check'] or Notice: Undefined index: check in path\to\filecheck.php on line 2 The file does not exist This post has been edited by mahirharoon: Dec 15 2007, 02:32 PM |
