  1. This is a question about dynamic links. At the moment I have a dynamic page from a table, I'll call it tableA. The links all work fine, so when clicked, information is displayed from the table. The issue will be when I come to create a new table entry. This new pages (or entry), will itself contain a link to other information. Assuming I have the required information in tableA, how do I activate a dynamic link from within a page that itself dynamically produced? I use PDO for the link to the database, and the page that shows the text uses a form, with buttons to allow the user to select a menu item. The php: <?php // Connect to the databaase $PDO = new PDO("mysql:host=****;dbname=****", "****", "****"); // set the PDO error mode to exception $PDO->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); // Set up defaults $current_title = ""; $current_page_data = ""; // Check if the user posted the page if($_SERVER['REQUEST_METHOD'] == 'POST') { // Check if user pressed a menu button if(isset($_POST["menu"])) { // User has selected a menu, meaning a page was selected, now load the page $current_title = filter_input(INPUT_POST, "menu"); // Now get current data from the database, if the page was never created, add it to the database $stmt = $PDO->prepare("SELECT * FROM pages WHERE pageheader=?"); $stmt->execute([$current_title]); $row = $stmt->fetch(); if($row) { // Page is in the databaswe already, load the text for it if(isset($row["pagetext"]) AND trim($row["pagetext"])!="") { $current_page_data = $row["pagetext"]; } } else { // Page was never created, add it with blank text $current_page_data = "This page is under contruction!<br><br>Please check back again later!"; } } } ?> The form (partial): <form name="****form" method="post" action="#"> <table id="timeline"> <tr> <td id="contentMenu"> <span class="item"> <div class="dropdown"> <button class="dropdownButton">Pre 3150 BC</button> <div class="dropdownContent"> <button name="menu" type="submit" value="Predynastic Egypt">Predynastic Egypt</button> <button name="menu" name="menu" value="Lower Egypt">Lower Egypt</button> <button name="menu" type="submit" value="Upper Egypt">Upper Egypt</button> <button name="menu" type="submit" value="Upper and Lower Egypt">Upper &amp; Lower Egypt</button> </div> </span> .... </td> </tr> </table> </form> <!-- page content --> <hr> <h1 class="center"><?php echo $current_title; ?></h1> <hr> <?php echo $current_page_data; ?>
  2. Hello. What I have created is a menu with links. The links will display content on the page from a database. I have the links with id displayed, but nothing is displayed when the link is clicks. I have seen isset() and $_GET used but not a form and I don't know how to change the code to allow the display of data using ID. My site is local, and I am using XAMPP. The database connections work. This is my code: // query $query = "SELECT * FROM topmenu ORDER BY id ASC"; $row = $PDO->query($query); .... <table class="topmenu"> <tr> <td> <h1 class="siteName">site title</h1> </td> <?php foreach($row as $data) { ?> <td><a href="index.php?id=<?php echo $data['id']; ?>"> <?php echo $data['menuheader']; ?> </a></td> <?php } ?> </tr> </table> As a beginner, I would appreciate any help, no criticism of my code please! Also, is there a way of hiding the id in the url? Thanks in advance.
