    Thanks a lot for for the tutorial... I am new to MySQLi and im trying to use this script... my problem is that it redirects to the main page again.. meaning the info has been added I take it but it doesn't actually add any of the details, I have checked phpMyAdmin and it doesn't get added...I was wondering if you could help me with this, I have the following: <?php /* Allows the user to both create new records and edit existing records */ // connect to the database include("includes/connecti.php"); // creates the new/edit record form // since this form is used multiple times in this file, I have made it a function that is easily reusable function renderForm($title = '', $poster ='', $date = '', $story = '', $error = '', $id = '') { ?> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <title> <?php if ($id != '') { echo "Edit Record"; } else { echo "New Record"; } ?> </title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> </head> <body> <h1><?php if ($id != '') { echo "Edit Record"; } else { echo "New Record"; } ?></h1> <?php if ($error != '') { echo "<div style='padding:4px; border:1px solid red; color:red'>" . $error . "</div>"; } ?> <form action="" method="post"> <div> <?php if ($id != '') { ?> <input type="hidden" name="id" value="<?php echo $id; ?>" /> <p>ID: <?php echo $id; ?></p> <?php } ?> <strong>Title: *</strong> <input type="text" name="title" value="<?php echo $title; ?>"/><br/> <strong>Poster: *</strong> <input type="text" name="poster" value="<?php echo $poster; ?>"/> <strong>Date: *</strong> <input type="text" name="date" value="<?php echo $date; ?>"/> <strong>Story: *</strong> <input type="text" name="story" value="<?php echo $story; ?>"/> <p>* required</p> <input type="submit" name="submit" value="Submit" /> </div> </form> </body> </html> <?php } /* EDIT RECORD */ // if the 'id' variable is set in the URL, we know that we need to edit a record if (isset($_GET['id'])) { // if the form's submit button is clicked, we need to process the form if (isset($_POST['submit'])) { // make sure the 'id' in the URL is valid if (is_numeric($_POST['id'])) { // get variables from the URL/form $id = $_POST['id']; $title = htmlentities($_POST['title'], ENT_QUOTES); $poster = htmlentities($_POST['poster'], ENT_QUOTES); $date = htmlentities($_POST['date'], ENT_QUOTES); $story = htmlentities($_POST['story'], ENT_QUOTES); // check that firstname and lastname are both not empty if ($title == '' || $poster == '' || $date == '' || $story == '') { // if they are empty, show an error message and display the form $error = 'ERROR: Please fill in all required fields!'; renderForm($title, $poster, $date, $story, $error, $id); } else { // if everything is fine, update the record in the database if ($stmt = $mysqli->prepare("UPDATE news SET title = ?, poster = ?, date = ?, story = ? WHERE id=?")) { $stmt->bind_param("ssi", $title, $poster, $date, $story, $id); $stmt->execute(); $stmt->close(); } // show an error message if the query has an error else { echo "ERROR: could not prepare SQL statement."; } // redirect the user once the form is updated header("Location: view.php"); } } // if the 'id' variable is not valid, show an error message else { echo "Error!"; } } // if the form hasn't been submitted yet, get the info from the database and show the form else { // make sure the 'id' value is valid if (is_numeric($_GET['id']) && $_GET['id'] > 0) { // get 'id' from URL $id = $_GET['id']; // get the recod from the database if($stmt = $mysqli->prepare("SELECT * FROM news WHERE id=?")) { $stmt->bind_param("i", $id); $stmt->execute(); $stmt->bind_result($id, $title, $poster, $date, $story); $stmt->fetch(); // show the form renderForm($title, $poster, $date, $story, NULL, $id); $stmt->close(); } // show an error if the query has an error else { echo "Error: could not prepare SQL statement"; } } // if the 'id' value is not valid, redirect the user back to the view.php page else { header("Location: view.php"); } } } /* NEW RECORD */ // if the 'id' variable is not set in the URL, we must be creating a new record else { // if the form's submit button is clicked, we need to process the form if (isset($_POST['submit'])) { // get the form data $title = htmlentities($_POST['title'], ENT_QUOTES); $poster = htmlentities($_POST['poster'], ENT_QUOTES); $date = htmlentities($_POST['date'], ENT_QUOTES); $story = htmlentities($_POST['story'], ENT_QUOTES); // check that firstname and lastname are both not empty if ($title == '' || $poster == '' || $date == '' || $story == '') { // if they are empty, show an error message and display the form $error = 'ERROR: Please fill in all required fields!'; renderForm($title, $poster, $date, $story, $error); } else { // insert the new record into the database if ($stmt = $mysqli->prepare("INSERT news (title, poster, date, story) VALUES (?, ?, ?, ?)")) { $stmt->bind_param("ss", $title, $poster, $date, $story); $stmt->execute(); $stmt->close(); } // show an error if the query has an error else { echo "ERROR: Could not prepare SQL statement."; } // redirect the user header("Location: view.php"); } } // if the form hasn't been submitted yet, show the form else { renderForm(); } } // close the mysqli connection $mysqli->close(); ?>
