  1. Hi I am trying to use a For statement to create multiple input boxes: <?php for ($i = 1; $i <= $x; $i++);?><post Form><input class-"text-primary" type="text" class="form-control" name="username<?php$i;?>" maxle ngth="40" id="usernameField" placeholder="Your Username" /> <submit type button> And then retreiv the results using POST if ($_SERVER['REQUEST_METHOD'] == 'POST'){ $trimmed = array_map('trim', $_POST); for ($j = 1; $j < $attendeeNO; $j++){ // Check for a username: if (preg_match ('/^\w{4,20}$/', $trimmed["username$j"])) { $un = mysqli_real_escape_string ($dbc, $trimmed["username$j"]); } else { echo '<p class="error">Please enter username' .$j. '!</p>'; }}} However, I cannot seem to retreive the HTML form input boxes and mainpulate them with the $_POST array. The error is that the index is undefined? The problem is that the index is not correctly being passed to the post array upon submission. I have been trying various forms of quotation for the submission but am wondering if I am correctly retrieving / looping through the $_POST form upon submission. Any thoughts? Thanks, Karen
