    <p>After searching for an answer for about five days for a solution to my problem, I figured I might as well ask for some help. I am working on a cascading drop down that I can´t seem to get to work.</p> <p>The Mysql data are saved in one table where we have country (varchar) and regions (varchar), names of document (varchar), links to documents (varchar) as well as date added (timestamp). </p> <p>I want the first dropdown to lead to the second drop down that contains the regions. I looked at many tutorials but I can´t seem to find one that uses either PDO or Mysqli, that works. When the form is submitted I want the name of the document to appear as hyperlink and the date added.</p> <p>I got started using: <a href="http://www.electrictoolbox.com/json-data-jquery-php-mysql/" rel="nofollow">http://www.electrictoolbox.com/json-data-jquery-php-mysql/</a></p> <p>This is my code:</p> <p>"Drop down site"</p> <pre><code> &lt;form&gt; &lt;select name="country" id="countryname"&gt; &lt;option&gt;Sverige&lt;/option&gt; &lt;option&gt;Norge&lt;/option&gt; &lt;option&gt;Danmark&lt;/option&gt; &lt;option&gt;Finland&lt;/option&gt; &lt;/select&gt; &lt;select name="region" id="regionname"&gt; &lt;/select&gt; &lt;/form&gt; </code></pre> <p>Javascript (jQuery)</p> <pre><code>function popregion() { $.getJSON('/blanketter_func2.php', {countryname:$('#countryname').val()}, function(data) { var select = $('#regionname'); var options = select.prop('options'); $('option', select).remove(); $.each(data, function(index, array) { options[options.length] = new Option(array['region']); }); }); } $(document).ready(function() { popregion(); $('#countryname').change(function() { popregion(); }); }); </code></pre> <p>The function file (blanketed_func2.php).</p> <pre><code>&lt;?php $dsn = "mysql:host=localhost;dbname=blanketter"; $username = "root"; $password = "root"; $pdo = new PDO($dsn, $username, $password); $rows = array(); if(isset($_GET['countryname'])) { $stmt = $pdo-&gt;prepare("SELECT region FROM blanketter WHERE country = ? ORDER BY region"); $stmt-&gt;execute(array($_GET['countryname'])); $rows = $stmt-&gt;fetchAll(PDO::FETCH_ASSOC); } echo json_encode($rows); ?&gt; </code></pre> <p>I am using jQuery version 1.9.1 and any help would be appreciated!</p> <p>/Sten</p>

    2. COWould you recommend making two separate tables where the regions and countries would have a corresponding value (id). I am sorry if it is a dumb question but this is all kind of new to me.

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.

SQuiL has stopped working due to an internal error.

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