    <p>After allot of searching around SO and other forums also stumbling over various php function documentation, I tried to edit a function that I found on here(converts URLs to clickable links) so it will also handle embedded video, unfortunately my skill set is poor and I believe I don't fully understand <code>create_function()</code> to be successful at this.</p> <p>So here's my scrambled egg code:</p> <pre><code>private function _check4Links($text){ $pattern = '#\b(([\w-]+://?|www[.])[^\s()&lt;&gt;]+(?:\([\w\d]+\)|([^[:punct:]\s]|/)))#'; $callback = create_function('$matches', ' $url = array_shift($matches); $url_parts = parse_url($url); if(preg_match("%(?:youtube\.com/(?:user/.+/|(?:v|e(?:mbed)?)/|.*[?&amp;]v=)|youtu\.be/)([^"&amp;?/ ]{11})%i", $url, $match)){ return sprintf(\'&lt;iframe title="YouTube video player" class="youtube-player" type="text/html" width="400" height="244" src="http://www.youtube.com/embed/\'.$match[1].\'" frameborder="0" allowFullScreen&gt;&lt;/iframe&gt;\', $url, $text); }else{ $text = parse_url($url, PHP_URL_HOST) . parse_url($url, PHP_URL_PATH); $text = preg_replace("/^www./", "", $text); $last = -(strlen(strrchr($text, "/"))) + 1; if ($last &lt; 0) { $text = substr($text, 0, $last) . "&amp;hellip;"; } return sprintf(\'&lt;a target="_blank"rel="nofollow" href="%s"&gt;%s&lt;/a&gt;\', $url, $text); }'); return preg_replace_callback($pattern, $callback, $text); } </code></pre> <p>I should also mention that i'm <strong>not</strong> looking for someone to just show me the correct code, I'm looking for someone to explain to me why my code is not working and what i am doing wrong. Thank you for your time :)</p>

    1. COWhy are you using lambda-function for this? Can't see any dynamic generated code inside it. I think that it'll be much easier to debug with normal function. Moreover, you don't have any placeholders for video `sprintf()`. That's not an error though.

    2. CO@WASD42 Well that's just what they were using so I just tried to edit it as little as possible trying to keep most of the code intact. Would you suggest I do it normally?

    3. COYes, I will :) it seems that there is an unclosed quote (") in your regexp.

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).
