How do i put this code on my web site?

November 12, 2005 5:59 AM

Can anyone guide me in creating a page just like this one?

What i'd like to do is exactly the same as that page. Have visitors add phrases to a pool, and have the java script display the phrases randomly on a specified page. My coding knowledge is limited, especially in php, so any tutorials or similar scripts would be helpful. I've already tried to contact the owner of the site for assistance, but they never replied.

Best answer: This would be best done with a database (mysql) in conjunction with PHP. But that may involve more complexity than you want.

If you're looking for a flat-file solution, see this documement about pulling random lines from a file.

This explains how to write to the flat file.

You will also want to learn file locking, so that two people don't try to write data to the file at once (which might corrupt the file).

Best answer: Also, make sure you sanitise the phrases in some way before they're output back onto your site's pages. Otherwise someone could come along and stick in whatever HTML or JavaScript that they wanted, and have it display on your site as if it was part of the legitimate HTML.

A crude but easy way would be to use something like htmlentities to convert all the <'s and >'s into harmless HTML entities.

Whoops, I actually meant htmlspecialchars, which only translates the dangerous characters (&, <, >).
