[wp-hackers] Plugin custom page

[Bryan Gentry]

Chris,

You will want to use the template_redirect hook:

          add_action( 'template_redirect', 'voucher_template' );
          function voucher_template() {
              //check your query variables to determine whether a voucher
is being displayed.
             if ( $voucher_is_being_displayed ) {
                       add_filter( 'the_content', 'voucher_content' );
                      }
            }

Then you create a function that accepts the content and changes it
appropriately:

             function voucher_content($content) {
                          //now add or change whatever you want to $content
                          return $content;
              }

My Easy FAQ With Expanding Text plugin uses this, as does an unpublished
plugin that allows one of my clients to create event pages.So far, this
does the trick and is working with several different themes.

> I'm currently updating my VoucherPress plugin which allows WP admins
> to create vouchers that visitors can download. One of the optional
> features of a voucher is to require the user to register their name
> and email address to get a link to download the voucher. When the user
> clicks a link to the voucher they should see a form asking for their
> name and email address. If the voucher doesn't require their email
> then they get the PDF immediately.

> To support any template I need the form to be output using something
> like the "the_content" filter, so it appears as if it's a real page.
> The URL which is requested is something like
> mysite.com/?voucher=abc123. This looked like it was going to work,
> however when the front page is set to display multiple posts each post
> gets its content filtered leading to multiple voucher forms on the
> page. What would be the best way to handle this kind of custom page in
> my plugin, seeing as just calling get_header() and get_footer() (which
> is what the current version of the plugin does) may miss out large
> parts of a templates design?
>
> 1) Use "the_content" and somehow break the loop?
> 2) Use a custom URL (e.g. "mysite.com/voucherpress/abc123") and map
> that to the page/single/index page?
> 3) Something else?
