  1. I have some problem with this tutorial. I made a bit change to suit my forum script I building. Heres what my changed files. EDIT.PHP <?php //create_cat.php include 'connect.php'; include 'header.php'; include 'modules/bbcode.php'; /* EDIT.PHP Allows user to edit specific entry in database */ // creates the 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($id, $firstname, $error) { ?> <html> <head> <title>Edit Record</title> </head> <body> <?php // if there are any errors, display them if ($error != '') { echo '<div style="padding:4px; border:1px solid red; color:red;">'.$error.'</div>'; } ?> <form action="" method="post"> <input type="hidden" name="id" value="<?php echo $id; ?>"/> <div> <p><strong>ID:</strong> <?php echo $id; ?></p> <strong>Content*</strong> <input type="text" name="firstname" value="<?php echo $firstname; ?>"/><br/> <p>* Required</p> <input type="submit" name="submit" value="Submit"> </div> <a href="/settings.php">Back</a> </form> </body> </html> <?php } // connect to the database // check if the form has been submitted. If it has, process the form and save it to the database if (isset($_POST['submit'])) { // confirm that the 'id' value is a valid integer before getting the form data if (is_numeric($_POST['id'])) { // get form data, making sure it is valid $id = $_POST['post_id']; $firstname = mysql_real_escape_string(htmlspecialchars($_POST['post_content'])); // check that firstname/lastname fields are both filled in if ($firstname == '') { // generate error message $error = 'ERROR: Please fill in all required fields!'; //error, display form renderForm($id, $firstname, $error); } else { // save the data to the database mysql_query("UPDATE posts SET post_content='$firstname' WHERE post_id='$id'") or die(mysql_error()); // once saved, redirect back to the view page header("Location: settings.php"); } } else { // if the 'id' isn't valid, display an error echo 'Error!'; } } else // if the form hasn't been submitted, get the data from the db and display the form { // get the 'id' value from the URL (if it exists), making sure that it is valid (checing that it is numeric/larger than 0) if (isset($_GET['id']) && is_numeric($_GET['id']) && $_GET['id'] > 0) { // query db $id = $_GET['id']; $result = mysql_query("SELECT * FROM posts WHERE post_id=$id") or die(mysql_error()); $row = mysql_fetch_array($result); // check that the 'id' matches up with a row in the databse if($row) { // get data from db $firstname = $row['post_content']; // show form renderForm($id, $firstname, ''); } else // if no match, display result { echo "No results!"; } } else // if the 'id' in the URL isn't valid, or if there is no 'id' value, display an error { echo 'Error!'; } } include 'footer.php'; ?> and NEW.PHP <?php //create_cat.php include 'connect.php'; include 'header.php'; /* NEW.PHP Allows user to create a new entry in the database */ // creates the new record form // since this form is used multiple times in this file, I have made it a function that is easily reusable function renderForm($first, $last, $error) { ?> <html> <head> <title>New Record</title> </head> <body> <?php // if there are any errors, display them if ($error != '') { echo '<div style="padding:4px; border:1px solid red; color:red;">'.$error.'</div>'; } ?> <form action="" method="post"> <div> <strong>Content: *</strong> <input type="textarea" name="firstname" value="<?php echo $first; ?>" /><br/> <p>* required</p> <input type="submit" name="submit" value="Submit"> </div> </form> </body> </html> <?php } // check if the form has been submitted. If it has, start to process the form and save it to the database if (isset($_POST['submit'])) { // get form data, making sure it is valid $firstname = mysql_real_escape_string(htmlspecialchars($_POST['post_content'])); // check to make sure both fields are entered if ($firstname == '') { // generate error message $error = 'ERROR: Please fill in all required fields!'; // if either field is blank, display the form again renderForm($first, $last, $error); } else { // save the data to the database mysql_query("INSERT posts SET post_content='$firstname'") or die(mysql_error()); // once saved, redirect back to the view page header("Location: settings.php"); } } else // if the form hasn't been submitted, display the form { renderForm('','',''); } include 'footer.php'; ?> In both Im getting error "ERROR: Please fill in all required fields" if I want to change something or add. The delete option is working.
