Execute php script from snippet in page with friendly URL

I hope I’m posting this in the right place.

I have a site that is up and running and am trying to add a simple php script that interacts with another database, a calendar, to one of the pages. The code runs fine from a static page with a .php extension. But, when I move the code to a snippet and then include the snippet in a page within the ModX framework, it no longer works.

The site is rewriting the URLs to have .html extensions. So, I thought that might be the issue. So, I’ve added code to the .htaccess file to parse php in html pages. But, that didn’t have any effect.

You can see the working version here...

And, the snippet version...

Any help would be much appreciated.

Thanks.

How are you calling the snippet? An interactive snippet like that needs to be called uncached. [!...!] for Evo, and [[!...]] for Revo.

That was it! Thank you!

That’s because of how the parser more-or-less works. A snippet is evaluated (putting its code through the PHP eval() function) and its output is inserted into the page where the snippet tags were. If this output is a form, it will have the usual submit button and action attributes. Now, if that whole page, snippet and all, gets cached, when the submit requests the page again with the POST values from the form, there is no snippet code to process those POST values! All you’ll get is what was in the page when it was cached.

An uncached snippet isn’t processed immediately; the page is processed and cached, then in a post-processing process a few odds and ends are cleaned up, including evaluating all uncached snippets. This post-processing is also performed on pages taken from cache, so the uncached snippet will get evaluated in all cases. Thus the re-requested page from the form’s action attribute will get its POST values processed.

While Revo doesn’t use the PHP eval() function for snippet code (it writes the snippet code to a .php file and includes it) the cached/uncached feature has the same effect.
