    <p>I'm building a contact form using PHP with jQuery validation and I wanted them both to have the same email pattern. I looked into the Validation plugin source code and found this:</p> <pre><code>/^((([a-z]|\d|[!#\$%&amp;'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\$%&amp;'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?$/i </code></pre> <p><a href="https://github.com/jzaefferer/jquery-validation/blob/1.8.1/jquery.validate.js#L1008" rel="nofollow">https://github.com/jzaefferer/jquery-validation/blob/1.8.1/jquery.validate.js#L1008</a></p> <p>I tried plugging that into my existing php form validation, but it no longer recognizes anything. I tried various online regex test tools and some told me there was an error. Most didn't say anything more, but one said... </p> <blockquote> <p>preg_match() [function.preg-match]: Compilation failed: PCRE does not support \L, \l, \N, \U, or \u at offset 45</p> </blockquote> <p><a href="http://www.solmetra.com/scripts/regex/index.php" rel="nofollow">http://www.solmetra.com/scripts/regex/index.php</a></p> <p>I searched for unicode capital L, which is u004C, but I can't find any \u004C in the regex, so I don't know what is wrong or how to fix this.</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.

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