    <p>I have a search form like this in a file form.php. It works great, the problem I am facing is that I use class/methods(functions). For example I have this method that calls logo and manu bar.</p> <pre><code> //$this-&gt;output is just a method that echos, that's all it does function header() { $this-&gt;output('&lt;DIV CLASS="header"&gt;'); $this-&gt;logo(); include('form.php'); $this-&gt;links(); $this-&gt;header_clear(); $this-&gt;output('&lt;/DIV&gt;'); } </code></pre> <p>Like the above, the form shows perfectly, but when I choose a category it takes me to form.php, and it ruins everything. (form.php is just a form)</p> <p>I know the problem is here</p> <pre><code> onChange="javascript:this.form.action='form.php'; this.form.submit() </code></pre> <p>Without javascript I couldn't get the category values, the page is not refreshing, so $_POST['cat'] is empty.</p> <p>What is a better way to refresh the page without taking me to different one?</p> <p>I know probably this all confusing, just bear with me.</p> <pre><code> &lt;form enctype="multipart/form-data" name="form" id="form" action="form.php" method="get"&gt; &lt;SELECT name="cat" onChange="javascript:this.form.action='form.php'; this.form.submit()"&gt; &lt;option value="" &gt;Categories&lt;/option&gt; &lt;?php $z = "0" ; //Select categories form database $category =db_select_categories($z); if(is_array($category)) { foreach($category as $rowc) { $id_cat = htmlentities($rowc['id_cat'], ENT_QUOTES); $cat_name = htmlentities($rowc['cat_name'], ENT_QUOTES, 'utf-8'); $cat_name = stripslashes($cat_name); echo "&lt;option style=\"background-color:#FFCC99\" disabled&gt;".$cat_name." &lt;/option&gt;"; $categories = db_select_categories($id_cat); if(is_array($categories)) { foreach($categories as $row) { $id = htmlentities($row['id_cat'], ENT_QUOTES); $name = htmlentities($row['cat_name'], ENT_QUOTES, 'utf-8'); $name = stripslashes($name); if ( $cat == $id ) { echo "&lt;option value='".$id."'selected&gt; ".$name."&lt;/option&gt;"; } else { echo "&lt;option value=".$id."&gt; ".$name."&lt;/option&gt;"; } } } } } echo "&lt;/SELECT&gt;"; ?&gt; &lt;div&gt; &lt;?php if(!empty($cat)) { //Outputs a populated select option depending on category display_search_options($cat); } ?&gt; &lt;/div&gt; </code></pre>

    2. COYou will have to use AJAX in order to do an asynchronous form submit. Then handle the response of that call. This is the only way to not refresh the entire page.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
