    <p>i have made a webform, and i have a script for the handeling of this form (php) this script works fine, but i also made a javascript error checker, now when i try to get some php in that script, it somehow bugs, and doesn't check my errors, in javascript,</p> <p>below you will find the code i wrote for the error handeling, i'm not finished yet, but i'm currently stuck, since i need to go to my database to check something, and the javascript error handler bugs there.</p> <p>quick walktrough: I myself have 0 karma for the purposes of testing this error handling. i click submit, and even tho i haven't filled in my username, it doesn't show an error. and brings me directly to the php handler wich does find errors.</p> <pre><code>Do you like the content on our website?

    3. COI put your code into a local page on my machine (after stubbing the UID and karma points) and I correctly get the alert dialog if karma is less than 500 or I leave the username field blank. Is it possible that you have a blank space in the username field (perhaps your getUN() returns " ")? Otherwise I would check to see if you have other script errors on the page using Firebug in Firefox, or the Developer console in Chrome.

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).
