    I've made this code for a very simple registration form practice: //assign form variables $firstname = $_POST['firstname']; $lastname = $_POST['lastname']; $username = $_POST['username']; function clean_names($dirty_name) { strip_tags($dirty_name); str_replace(' ', '', $dirty_name); ucfirst(strtolower($dirty_name)); //return $dirty_name; } $names = array($firstname, $lastname, $username); if(isset($_POST['register_button'])) { // WHY IS THIS FUNC CALL NOT WORKING?? foreach($names as $name) { clean_names($name); } echo "First Name: " . $firstname . "<br>"; echo "Last Name: " . $lastname . "<br>"; echo "Username: " . $username . "<br>"; } The values are returned but they haven't been put through the clean_names function. I'm really new with PHP. Can someone tell me why this isn't working? Thank you

    When I insert the line: require '../../config/config.php'; to includes/form_handlers/register.php I get this error: Warning: require(../../config/config.php): failed to open stream: No such file or directory in /opt/lampp/htdocs/qcicnews/includes/form_handlers/register.php on line 2 Fatal error: require(): Failed opening required '../../config/config.php' (include_path='.:/opt/lampp/lib/php') in /opt/lampp/htdocs/qcicnews/includes/form_handlers/register.php on line 2 I'm so confused and frustrated that I can't get this to work It seems like it's looking in the includes/form_handlers directory for the config.php file which would imply it's not recognizing the '..' to move one directory up but I've also tried using an absolute path and got pretty much the same message.

    This is my first post on your forums. I've some problems with a registration form that I've been trying to work out for 2+ days now, asking about it here is a last resort - I have a config.php file located at config/config.php there's a register.php file in the sites root directory and a includes/form_handlers/register.php My config.php file is: <?php ob_start(); session_start(); $timezone = date_default_timezone_set("America/Cancun"); $servername = "localhost"; $username = "root"; $password = ""; $database = "social"; $conn = mysqli_connect($servername, $username, $password, $database); if (mysqli_connect_error()) { echo "Failed to connect: " . mysqli_connect_error(); } ?> This is my register.php file: <?php require 'config/config.php'; require 'includes/form_handlers/register.php'; ?> <!-- REMOVED THE <HEAD> SECTION --> <body class="login-img3-body"> <div class="container"> <form class="login-form" action="includes/form_handlers/register.php" method="POST"> <div class="login-wrap"> <p class="login-img"><i class="icon_lock_alt"></i></p> <div class="input-group"> <span class="input-group-addon"><i class="icon_profile"></i></span> <input type="text" class="form-control" name="fname" placeholder="First Name" value="<?php if(isset($_SESSION['fname'])) { echo $_SESSION['fname']; } ?>" required> <br> <?php if(in_array("Your first name must be 2-50 characters long.<br>", $error_array)) echo "<span style='color: #AD0303;'>Your first name must be 2-50 characters long.</span><br>"; ?> </div> <div class="input-group"> <span class="input-group-addon"><i class="icon_profile"></i></span> <input type="text" class="form-control" name="lname" placeholder="Last Name" value="<?php if(isset($_SESSION['lname'])) { echo $_SESSION['lname']; } ?>" required> <br> <?php if(in_array("Your last name must be 2-50 characters long.<br>", $error_array)) echo "<span style='color: #AD0303;'>Your last name must be 2-50 characters long.</span><br>"; ?> </div> <div class="input-group"> <span class="input-group-addon"><i class="icon_mail_alt"></i></span> <input type="text" class="form-control" name="email" placeholder="Email" value="<?php if(isset($_SESSION['email'])) { echo $_SESSION['email']; } ?>" required> </div> <div class="input-group"> <span class="input-group-addon"><i class="icon_mail_alt"></i></span> <input type="text" class="form-control" name="email2" placeholder="Confirm Email" value="<?php if(isset($_SESSION['email2'])) { echo $_SESSION['email2']; } ?>" required> <br> <?php if(in_array("Email already in use<br>", $error_array)) echo "<span style='color: #AD0303;'>Email already in use</span><br>"; else if(in_array("Invalid Email<br>", $error_array)) echo "<span style='color: #AD0303;'>Invalid Email</span><br>"; else if(in_array("Emails don't match<br>", $error_array)) echo "<span style='color: #AD0303;'>Emails don't match</span><br>"; ?> </div> <div class="input-group"> <span class="input-group-addon"><i class="icon_key_alt"></i></span> <input type="password" class="form-control" name="pwd" placeholder="Password" required> </div> <div class="input-group"> <span class="input-group-addon"><i class="icon_key_alt"></i></span> <input type="password" class="form-control" name="pwd2" placeholder="Confirm Password" required> <br> <?php if(in_array("Your passwords don't match.<br>", $error_array)) echo "<span style='color: #AD0303;'>Your passwords don't match.</span><br>"; else if(in_array("Your password must contain English characters or numbers.<br>", $error_array)) echo "<span style='color: #AD0303;'>Your password must contain English characters or numbers.</span><br>"; else if(in_array("Your password must be 5-30 characters long.<br>", $error_array)) echo "<span style='color: #AD0303;'>Your password must be 5-30 characters long.</span><br>"; ?> </div> <input class="btn btn-info btn-lg btn-block" type="submit" name="register" value="Register"> </div> <?php if(in_array("<span style='color: #14C800;'>You're all set!

When I don't use it I get a party of errors all connected to it not recognizing the $conn variable: Notice: Undefined variable: conn in /opt/lampp/htdocs/qcicnews/includes/form_handlers/register.php on line 43 Warning: mysqli_query() expects parameter 1 to be mysqli, null given in /opt/lampp/htdocs/qcicnews/includes/form_handlers/register.php on line 43 Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, null given in /opt/lampp/htdocs/qcicnews/includes/form_handlers/register.php on line 46 There's about 6 more that look like the ones above but from different lines where $conn is referenced, I just deleted them for brevity sake. I'm pretty new to PHP and this is the most difficult situation I've encountered so far, can someone help me find the way here?
