Body
<p>I have a form (#searchform) that I want to submit multiple times without reloading the page, so I use jQuery and the post-method. I want to store which checkboxes are checked in a variable named <em>target</em> (array, list or whatever) and which radio button is selected in the variable <em>diff</em>. </p> <p>The variables also need to be available in PHP. I tried passing them as <em>ftar</em> and <em>fdiff</em> in so many ways, but nothing worked.</p> <p>Any help is much appreciated! </p> <p>JQuery in submit.js:</p> <pre><code>$(document).ready(function () { var target = new Array(); $('#searchform input:checked').each(function() { target.push($(this).attr('value')); }); var diff = $('#searchform').find("input[class='diff']").val(); $.post('index.php', {ftar: target, fdiff: diff}); }); </code></pre> <p>HTML and PHP in index.php:</p> <pre><code><!DOCTYPE html> <html lang="en-US"> <head> <title></title> <script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script> <script src="js/submit.js"></script> </head> <body> <?php ini_set('display_errors',1); error_reporting(E_ALL); $link = new mysqli("localhost", "root", "password", "mytable"); if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $target = $_POST['ftar']; $diff = $_POST['fdiff']; ?> <div id="right"> <div class="content"> <form id="searchform" method="POST" action="/"> <input type="checkbox" value="Check1"> <input type="checkbox" value="Check2"> <input type="checkbox" value="Check3"> <input type="radio" class="diff" value="Radio1"> <input type="radio" class="diff" value="Radio2"> </form> </div> </div> </body> </html> </code></pre>

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.
