    <p>Okay, I have given up on figuring this out. I am creating a simple hook system, files are placed into a folder called hooks/. </p> <p>Here is an example hook</p> <pre><code>&lt;?php //Testhook function exampleHook() { echo 'Example hook as been run'; } //Register hook (start is the hook type (where to be called), exampleHook is the function //name and TRUE if it is enabled or not. $hooks-&gt;RegisterHook('start','exampleHook','TRUE'); ?&gt; </code></pre> <p>This system will load all the functions into the page, they wont be executed just yet though.</p> <p>Now in the actual page heres what the code looks like:</p> <pre><code>&lt;?php include ("hooks.class.php"); $hooks = new hooks('hooks/'); ?&gt; &lt;html&gt; &lt;head&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8"&gt; &lt;title&gt;Hooks&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;p&gt;Start hooks should run below&lt;/p&gt; &lt;?php $hooks-&gt;callHooks('start'); ?&gt; &lt;p&gt;Start hooks should now finish&lt;/p&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>The callHooks function will execute any functions with the type 'start' in it. My problem is that in the testHook.php it cannot find the class $hooks, I've put the exampleHook into the same page and registered the function and it works perfectly but for some reason it cannot find the class $hooks even though the page is included.</p> <p>Here is the hooks class file:</p> <pre><code>&lt;?php class hooks { //Variable Initialisation private $hookDir; private $allHooks; public $debug = FALSE; private $debugDetails = array(); //Function runs when the class is called, sets the location and calls the function retrieveHooks() to include all the files function __construct($hookDir = "library/addHooks/hooks/") { $this-&gt;hookDir = $hookDir; $this-&gt;allHooks = array(); $this-&gt;retrieveHooks(); } public function retrieveHooks() { //Get all files located in hooks directory $hookFiles = scandir($this-&gt;hookDir); //Loop through the files and remove any that arnt a file foreach($hookFiles as $hookFile) { if (strlen($hookFile) &gt; 2) { //Include the file into the page include_once($this-&gt;hookDir . $hookFile); // START DEBUG SECTION OF CODE // if ($this-&gt;debug == TRUE) { $this-&gt;debugDetails[] = $this-&gt;hookDir . $hookFile . '&lt;br /&gt;'; } // END DEBUG SECTION OF CODE // } } } //Function is called by hook files to register themselves into the class file public function registerHook($hookType,$functionName,$hookEnabled = TRUE) { if ($hookEnabled == TRUE) { $singleHook = array('type' =&gt; $hookType, 'function' =&gt; $functionName); $this-&gt;allHooks[] = $singleHook; // START DEBUG SECTION OF CODE // if ($this-&gt;debug == TRUE) { $this-&gt;debugDetails[] = ($singleHook); } // END DEBUG SECTION OF CODE // } } //Execute the hooks based on the hook type, the programmer can add as many hooks as he wants public function callHooks($hookType) { //For each hook in the array foreach($this-&gt;allHooks as $singleHook) { //If hook is found for that type eg. start, end, middle if ($singleHook['type'] == $hookType) { //Call the function that is now included within the web page call_user_func($singleHook['function']); // START DEBUG SECTION OF CODE // if ($this-&gt;debug == TRUE) { $this-&gt;debugDetails[] = ($singleHook); } // END DEBUG SECTION OF CODE // } } } //Return the array of debug details public function fetchDebugDetails() { return $debugDetails; } //Test the class by outputting a simple message public function testClass() { $className = 'hooks'; echo 'Class is working: ' . $className; } } ?&gt; </code></pre> <p>Finally the error message:</p> <pre><code>Notice: Undefined variable: hooks in C:\wampserver64\www\Framework\library\addHooks\hooks\testHook.php on line 9 Fatal error: Call to a member function RegisterHook() on a non-object in C:\wampserver64\www\Framework\library\addHooks\hooks\testHook.php on line 9 </code></pre> <p>Thanks, for any clarification just ask :) This has been really bugging me.</p>

    1. CONote: `'TRUE'` is a string, you probably want to use a boolean: `true`

    2. COI know, I have a variable that usually goes there with a boolean value but I just put that there for the sake of reducing code :) Thanks

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.
