I have a form that calls another php script, and I need to know which variables the form passed to the new script to make a new query.

Is the method POST? Use $HTTP_POST_VARS Is the method GET? Use $HTTP_GET_VARS The track_vars setting must be on (in .htaccess, php.ini, or httpd.conf) for this to be useful. Also be aware that elements of the above arrays may _themselves_ be arrays - for instance, if you used array form variables (...name="some_stuff[]"...) Remember that if you are trying to process these arrays in a subroutine, you need to globalize them: function process_form() { global $HTTP_POST_VARS; ... } or refer to them as elements of the $GLOBALS array: function process_form() { ... $get_vars = $GLOBALS['HTTP_GET_VARS']; ... } -steve +--- unix and cats: -----------------------------------------------------+
