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 & 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; ?>
