Hey i have a tms and it uses the end; tag to sepperate the differnt parts, like display cat, display tut .. but if i use that it deletes all the html below where it is included so is there a way i can remove it without all the other segments merging into 1 /

You'll probably have to show us an example of what you are talking about, as I for one cannot visualize how this whole thing works.

This is the code and it is php included into a template which is the html look of the site... the bit where it shows the catagories work fine and the bit where it shows tuts in a catagory is fine but when its showing an actual tutorial it cuts of the footer of the html template and if i delete the exit; it merges all the php bits togeather on the tutorial page and if i just include the footer into the php in an echo it is missaligned. so i was wondering weather there is a way to delete the exit; but still make it function as normal?

Or use like a goto tag because what it seems is happening is its reading the code and the code says if the cat id is set show tuts in that cat.... and if tutid is set show that tutorial. But. if the exit is deleted it merges them so if the catid and tut id are set (which is true because it will have listed the the tuts of a certain cat eg ?cat=php ..... then when a tut is clicked it becomes ?catid=php&tutid=3 so both the functions are true and so show.

is there now fail safe like if tutid is set dnt show the catagory if any of this makes sence sorry for not organizing it and paragraphing im in a rush.

Simply change the logic of it, and make the entire thing an if/elseif/else block.

For instance, change this line.

if ($category == $request_cat) {

To.

elseif ($category == $request_cat) {

And this line.

if (!$category) {

To.

else{

Unless I'm mis-reading your code and what you are wanting to do, that should do it.

And by the way, don't use the $_REQUEST superglobal, its just opening you up to some un-reliable data. Plus, you shouldn't rely on automatic variables being passed from the $_GET superglobal. You need to use the actual array to access the data, otherwise you are opening yourself up to attacks, bugs, data conflict, server setting conflicts, and the like. Plus its just plain ignorant...
