I have a page that contains php code before any page. this all worked fine until I added

PHP Code:

$page1 = "<form action=".$_SERVER['PHP_SELF']." method=\"post\">
        <fieldset><legend>Add Page</legend>
            <label>page</label><input name=\"page\" type=\"text\" />
            <label>Description</label><input name=\"description\" type=\"text\" />
            <label>category</label><select name=\"category\">".$site->Fetch_Cats_Id()."</select>
            <input id=\"addpagesubmit\" type=\"submit\" value=\"Add Forum\" />
        </fieldset>
    </form>"; 


The $site class is fine, and I'm not getting any errors generated, or any html in the source for that matter - I'm just wanting to know what has happened.

I see one minor issue with quotation marks.. not sure if that helps with your overall problem though, might need to see some more code.

<form action=".$_SERVER['PHP_SELF']." method=\"post\">

should be:

<form action=\"" . $_SERVER['PHP_SELF'] . "\" method=\"post\">

during testing, put the below line to debug your code

ERROR_REPORTING(E_ALL);

when moving it to production, comment it.

I've tried that, and added the error reporting but its as soon as it reaches the end of the script it stops. I'm confused at this now, I've never had this problem before.

Any ideas please.

1. use simple quotes for that variable ... so no need to escape all of the others
2. remove $site->Fetch_Cats_Id() .. .maybe this is causing the error
3. also see if display errors is on if not ... add ini_set ('display_errors',1);

number 3: do I add that to my php script or what?
I've noticed it is when i call a function thats in a class.

first check your php configuration by printing phpinfo(); and look for display_errors and see if its on for the local value. If not you add ini_set ('display_errors',1) before ERROR_REPORTING(E_ALL);
