I have two questions. First of all, is the strategy I am planning (see below) for processing my form okay (I don’t want to use a plugin, so please don’t suggest this)?
I have developed a WordPress site whose pages are based on the following structure:
The footer has four sections that are pulled into the footer as posts with a category of “footer”. One of the sections is a short contact form. The footer is identical for every different page on the site.
I have the form being processed by a separate file, process_form.php. This works, but after the processing I want to use
header (location: url of current page); exit;
to return the user to the page from which the message was sent. I figure I should start a session in the header.php where I would save the url of the page the user is on in a session variable, then pick up that session variable in the form processor to use in the
header (location: url of current page); exit;
.
If that is a good strategy, what code would I use in the header to pick up the url of the current page? I have tried a number of things, none of which work.
