Ok, gotcha. } >$sel_image = "SELECT * from ppd_photos where ppd_id = '$_GET[ppdid]' AND place_holder = '$thephoto[0]'"; } What does this return? } } I'm a bit confused right now.. The query simply returns one row with all the htmlstuff [width, height, caption, image_holder, etc] for one image. In otherwords, $message might contain: --------------------- Hello world, look at my [b]cat[/b]: ###Image1### Nice, huh? And now look at my [b]dog[/b]: ###Image2### Not so nice, eh? --------------------- I'm using a big preg_replace call to replace any of that custom formatting tag [eg: [b][/b]] as well as the ###ImageX### tags. Instead of replacing ###Image1### with some formatting code, I need to look up ###Image1### in the database, which stores the formatting codes. So the in the above query, $thephoto[0] contains '###Image1###', since it is the first photo on the page. However, when preg_replace finds a 2nd photo, with a image_holder of ###Image2###, the select statement is still run against the first image place holder, ###Image1###. So I need to advance the counter before running the SQL statement If I leave out the sql stuff and do something like this: $patterns[3] = "/###Image(\d+)###/si"; $replacements[3] = "My Photograph\$1"; Then the page sucessfully substitutes "My Photograph1" for every place that $message contained ###Image1### and "My Photograph2" for every place that $message contained ###Image2###. So I need to somehow run preg_match on that part of $message in order to extract ###Image1###, ###Image2###, ###Image3###, etc from the message and look them up in the database. I think. :-\ } after the user enters in his stuff, he wants, in your CMS and before you } save it, parse it for all the special tags you have and keep track of it } somewhere. That way when you output it (in this script) you only need } to apply the necessary pattern/replacements before outputing it to the } browser. Good idea! Thanks very much! Thanks again for your help, and time, with this.
