  1. I'm making a registration form and I'm really new at it. I've had a look about at similar issues but feel like I've got my code set up right, I obviously don't. I have a registration_handler.php and a functions.php file. I'm simply trying to pass an array ($errors[]) from the functions that generate them to a function that prints them out on registration_handler.php. It seems so easy, but I'm not getting it. Here's my code: from functions.php: (this is just an example of one of the functions) // USERNAME (MANDATORY) //uses the clean_names() and checks for empty input function assign_username() { global $conn; $username = $_POST['username']; if(!$username){ $errors[] = "A username is mandatory"; echo "A username is mandatory <br>"; } else { $username = clean_names($username); } //check for duplicate username and return $username if doesn't exist already $username_check = mysqli_query($conn, "SELECT username FROM users WHERE username='$username'"); $number_rows = mysqli_num_rows($username_check); if($number_rows > 0) { $errors[] = "Username already in use <br>"; echo "Username already in use <br>"; } else { return $username; } return $errors; } // END USERNAME Also from functions.php, the function to print out the error array: //display error array function show_errors($errors) { print_r($errors); } and the function call from registration_handler.php: if(isset($_POST['register_button'])) { //assign clean form variables $firstname = assign_firstname(); $lastname = assign_lastname(); $username = assign_username(); $email = assign_email(); $password = assign_password(); $date = date("Y-m-d"); $errors = array(); show_errors($errors); } I'm intentionally leaving the username out to test this on the form but I only get returned Array() It echos "Username is mandatory" but it seems like it's not passing the error string to the error array Can anyone point me towards what I'm doing wrong, please. I appreciate the replies
  2. 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: " . $username . "<br>"; } The values are returned but they haven't been put through the clean_names function. I'm really new with PHP. Can someone tell me why this isn't working? Thank you
  3. I have two functions that execute an exe program (personal project for a minecraft back end.) Windows only. First one will execute the sending of commands (THIS ONE WORKS) /* check to see if admin is sending commands to terminal via web */ if(isset($_POST['command'])) { $content = $_POST['command']; writeMCCommandTxt($content); try { exec(SERVER_DIR.'mcCommand.exe',$output); } catch ( Exception $e ) { die ($e->getMessage()); } }// END COMMAND ENTRY This has been a head scratcher for most the week - any help or suggestions would be great!! thanks!! HTML <div id="commands"> <div id="command_input"> <form method="post" id="commandForm" action="index.php"> <label for="command" >Console Command:</label><br/> <input type="text" name="command" autofocuS/> <input type="submit" name="submit_command" value=" >> " /> &nbsp; <input type="button" value="Refresh page" onclick="location.reload(true);" /> </form> </div> </div> This is used to start the server // STARTING SERVER if(isset($_POST['startServerBtn'])){ try { exec(SERVER_DIR.'startServer.bat 2>&1' ,$output); } catch( Exception $e ) { die ($e->getMessage()); } } HTML <div id="server_control"> <ul> <li> <form action="index.php" method="post"> <input type="submit" value="START" id="startServerBtn" name="startServerBtn"/> </form> </li> </ul> </div> MCCOMMANDS.EXE will work from both browser(php) and file manager(tested) the STARTSERVER.EXE will NOT work from browser(php), but will work from file manager The function IS being accessed - debug is showing it going there, and it seems to be running Both exe's are in the same folder
