    <p>I have a problem with the Simple PHP DOM Parser. I basically have to scrape a catalogue site for the images and their titles. </p> <p>The site is have to scrape is <a href="http://pinesite.com" rel="nofollow">http://pinesite.com</a>.</p> <p>I have come up with the following code to do it (this will be called via AJAX):</p> <pre><code>&lt;?php include ('simple_html_dom.php'); $function = $_GET['function']; switch($function) { case 'subcat': $maincat = $_GET['cat']; $url = "http://www.pinesite.com/meubelen/index.php?".$maincat."&amp;lang=de"; $html = file_get_html($url); $data = $html-&gt;find('.box_166_content .act_path li a'); $output =""; foreach ($data as $subcat) { $title = $subcat-&gt;plaintext; $href = $subcat-&gt;href; $link['title'] = $title; $link['href'] =substr($href,10); $output[] = $link; } echo json_encode($output); $html-&gt;clear(); unset($html); unset($url); break; case 'images': $subcat = $_GET['subcat']; $url = "http://www.pinesite.com/meubelen/index.php?".$subcat; $html = file_get_html($url); $iframe = $html-&gt;find('#the_iframe',0); $url2 = $iframe-&gt;src; $html-&gt;clear(); unset($html); $html2 = file_get_html("http://www.pinesite.com/meubelen/".$url2); $titles = $html2-&gt;find('p'); $images = $html2-&gt;find('img'); $output=''; $i=0; foreach ($images as $image) { $item['title'] = $titles[$i]-&gt;plaintext; $item['thumb'] = $image-&gt;src; $item['image'] = str_replace('thumb_','',$image-&gt;src); $output[] = $item; $i++; } echo json_encode($output); break; } ?&gt; </code></pre> <p>So that's the "functions" file, the part that doesn't work is the last case.</p> <p>I don't know what wrong here, so I tested it (the last case) in a separate file (I put the URL that it gets from the iFrame (that part does work):</p> <pre><code>&lt;?php include_once "simple_html_dom.php"; $fullurl = "http://www.pinesite.com/meubelen/prog/browse.php?taal=nl&amp;groep=18&amp;subgroep=26"; $html = file_get_html($fullurl); $titles = $html-&gt;find('p'); $images = $html-&gt;find('img'); $output=''; $i=0; foreach ($images as $image) { $item['title'] = $titles[$i]-&gt;plaintext; $item['thumb'] = $image-&gt;src; $item['image'] = str_replace('thumb_','',$image-&gt;src); $output[] =$item; $i++; } echo json_encode($output); ?&gt; </code></pre> <p>Like I said the first part should return the same as the second (if you add ?function=images&amp;subcat=dichte-kast) but it doesn't. I'm guessing it is because I use the parser multiple times.</p> <p>Does anybody have a suggestion for me?</p>

    1. CONowhere have you actually checked if the url retrieval worked. Does `$url2` actually have a valid url in it? does `$html2` have some page contents? Your script utterly depends on the server's network connection being stable and the remote site being available, with no margin for ANY error.

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).
