    <p>Ok, I've tweaked your files slightly, you shouldn't be using mysql_ or the mysqli_ functions any more, just don't... And you certainly shouldn't be using mysql function in one file and mysqli functions in the other... I've switched them over to use PDO, you're script now isn't susceptible to SQL injection, and as far as I can tell it works just fine.</p> <p>index.html</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;script&gt; function showUser(str) { if(str=="") { document.getElementById("txtHint").innerHTML=""; return; } if(window.XMLHttpRequest) { xmlhttp=new XMLHttpRequest(); } else { xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange = function() { if(xmlhttp.readyState==4 &amp;&amp; xmlhttp.status==200) { document.getElementById("txtHint").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","getuser.php?q="+str,true); xmlhttp.send(); } &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;form&gt; &lt;?php try { $dbh = new PDO('mysql:dbname=theaterdb;host=localhost','tiger','tiger'); } catch (PDOException $e) { echo 'Connection failed: ' . $e-&gt;getMessage(); } $sql = "SELECT theater_name FROM theater;"; $sth = $dbh-&gt;prepare($sql); $sth-&gt;execute(); echo "&lt;select name='theater_name' id='course' onchange='showUser(this.value);'&gt;"; while($row = $sth-&gt;fetch(PDO::FETCH_ASSOC)) { echo "&lt;option value='" . $row['theater_name'] ."'&gt;" . $row['theater_name'].

Querying!

 
Guidance
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).
