    <p>I want to paginate the following filtered results from xml file:</p> <pre><code>&lt;?php //load up the XML file as the variable $xml (which is now an array) $xml = simplexml_load_file('inventory.xml'); //create the function xmlfilter, and tell it which arguments it will be handling function xmlfilter ($xml, $color, $weight, $maxprice) { $res = array(); foreach ($xml-&gt;widget as $w) { //initially keep all elements in the array by setting keep to 1 $keep = 1; //now start checking to see if these variables have been set if ($color!='') { //if color has been set, and the element's color does not match, don't keep this element if ((string)$w-&gt;color != $color) $keep = 0; } //if the max weight has been set, ensure the elements weight is less, or don't keep this element if ($weight) { if ((int)$w-&gt;weight &gt; $weight) $keep = 0; } //same goes for max price if ($maxprice) { if ((int)$w-&gt;price &gt; $maxprice) $keep = 0; } if ($keep) $res[] = $w; } return $res; } //check to see if the form was submitted (the url will have '?sub=Submit' at the end) if (isset($_GET['sub'])) { //$color will equal whatever value was chosen in the form (url will show '?color=Blue') $color = isset($_GET['color'])? $_GET['color'] : ''; //same goes for these fellas $weight = $_GET['weight']; $price = $_GET['price']; //now pass all the variables through the filter and create a new array called $filtered $filtered = xmlfilter($xml ,$color, $weight, $price); //finally, echo out each element from $filtered, along with its properties in neat little spans foreach ($filtered as $widget) { echo "&lt;div class='widget'&gt;"; echo "&lt;span class='name'&gt;" . $widget-&gt;name . "&lt;/span&gt;"; echo "&lt;span class='color'&gt;" . $widget-&gt;color . "&lt;/span&gt;"; echo "&lt;span class='weight'&gt;" . $widget-&gt;weight . "&lt;/span&gt;"; echo "&lt;span class='price'&gt;" . $widget-&gt;price . "&lt;/span&gt;"; echo "&lt;/div&gt;"; } } </code></pre> <p>Where <code>$xml-&gt;widget</code> represents the following xml:</p> <pre><code>&lt;hotels xmlns=""&gt; &lt;hotels&gt; &lt;hotel&gt; &lt;noofrooms&gt;10&lt;/noofrooms&gt; &lt;website&gt;&lt;/website&gt; &lt;imageref&gt;oias-sunset-2.jpg|villas-agios-nikolaos-1.jpg|villas-agios-nikolaos-24​.jpg|villas-agios-nikolaos-41.jpg&lt;/imageref&gt; &lt;descr&gt;blah blah blah&lt;/descr&gt; &lt;hotelid&gt;119&lt;/hotelid&gt; &lt;/hotel&gt; &lt;/hotels&gt; &lt;/hotels&gt; </code></pre> <p>Any good ideas?</p>

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).
