Body
<p>So I have a problem with updating a mysql table via mysqli in php.</p> <p>The database connection and class:</p> <pre><code><?php class testDB extends mysqli { private static $instance = null; private $user = "tester"; private $pass = "tester01"; private $dbName = "testdb"; private $dbHost = "localhost"; public static function getInstance() { if (!self::$instance instanceof self) { self::$instance = new self; } return self::$instance; } public function __clone() { trigger_error('Clone is not allowed.', E_USER_ERROR); } public function __wakeup() { trigger_error('Deserializing is not allowed.', E_USER_ERROR); } private function __construct() { parent::__construct($this->dbHost, $this->user, $this->pass, $this->dbName); if (mysqli_connect_error()) { exit('Connect Error (' . mysqli_connect_errno() . ') ' . mysqli_connect_error()); } parent::set_charset('utf-8'); } public function verify_credentials ($username, $password){ $username = $this->real_escape_string($username); $password = $this->real_escape_string($password); $result = $this->query("SELECT 1 FROM users WHERE user_username = '" . $username . "' AND user_password = '" . $password . "'"); return $result->data_seek(0); } public function get_vitae() { return $this->query("SELECT * FROM vitae"); public function update_vitae($text, $id) { $text = $this->real_escape_string($text); $this->query("UPDATE vitae SET vitae_text=".$text." WHERE vitae_id = ".$id); } } ?> </code></pre> <p>Here's the page code:</p> <p>Above the header we check the login by making sure there is a session started; then import the database class and the rest is called upon resubmitting the form to this same page:</p> <pre><code><?php session_start(); if (!array_key_exists("username", $_SESSION)) { header('Location: index.php'); exit; } require_once("includes/db.php"); $vitae_empty = false; if ($_SERVER['REQUEST_METHOD'] == "POST") { if ($_POST['text'] == "") { $vitae_empty = true; } else if ($_POST["text"]!="") { testDB::getInstance()->update_vitae($_POST["text"], $_POST["id"]); header('Location: manage.php' ); exit; } } ?> </code></pre> <p>In the body (the header and the rest of the html is imported via a 'require_once'):</p> <pre><code> <section> <div class="grid_3 header_line"><h2>Update for CV</h2></div> <div class="grid_3"> <?php $result = testDB::getInstance()->get_vitae(); $vitae = mysqli_fetch_array($result); ?> <form name="editvitae" action="editvitae.php" method="POST"> <textarea name="text" rows="50" cols="100"><?php echo $vitae['vitae_text'];?></textarea><br/> <?php if ($vitae_empty) echo "Please enter some text.<br/>";?> <input type="hidden" name="id" value="<?php echo $vitae["vitae_id"];?>" /> <br/> <input type="submit" name="savevitae" value="Save Changes"/> </form> </div> <div class="grid_3"> <p><a href="manage.php">&lsaquo; back to management consol</a></p> </div> </section> </code></pre> <p>After the 'body' tag:</p> <pre><code><?php mysql_free_result($result);?> </code></pre> <p>As you can see this pulls the 'vitae' text from the database then loops it to the same page with changes to update the table. It also check's to see that the 'text' box is not empty.</p> <p>This code works in another application; I'm not understanding why it won't work here. AND before you start warning me about injection and security I have stripped most of it out trying to find the problem with the update. It WILL go back in once I can figure that out.</p> <p>I have tried stripping the text check; different variable names; dumping the post values into an array before updating the database; putting the post values into static variables; checking all my spellings etc...</p> <p>I'm missing something and I feel like it's going to be simple.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
