I've created a plugin to help me load a chunk of html from a file, whose location is taken from a tv value, and is inserted into the document.
My plugin is executed 'OnLoadWebDocument', and works great for including embedded css or js by using the $modx->regClientStartupScript() method. Every document in my site has access to this tv, which i can fill in with a filename path to a html file that will load it and insert it into the head of my document. 'Well why don't you just use a chunk?' I hear you ask. Some of the files are long javascript files which I like in my text editor for the syntax highlighting, making it easier for editing.
My problem is that I can't use placeholders in the file I am using. If I change the system event to 'OnWebPagePrerender' then the regClientStartupScript method doesn't seem to work.
How can i put placeholders in my files, and have the plugin read and insert them using the regClientStartupScript method, and still get the placeholders parsed?
If I'm understanding you, I think the most straightforward solution is to get the file with file_get_contents(), replace the placeholder(s) yourself with str_replace(), then call regClientStartupScript().
Hmm yes - thanks for the reply Bob - I came to the same conclusion in the meantime also.
So, to confirm I understand it - does parsing of placeholders take place before 'OnLoadWebDocument', and that is why mine do not get parsed? (I'm only using a meek little '[(base_url)]' in this example - not a custom value)
I wish there was a flowchart that showed when all the system events get executed, in the context of requesting a url...
Here's my understanding of the sequence:
OnHandleRequest — Fires when any request for a resource is received in the front end.
OnWebPageInit — Fires after determination that the site is online and the requested resource is located.
OnLoadWebDocument — Fires after the requested resource is loaded, but before it is parsed.
OnParseDocument — Fires just before the MODX tags are processed.
OnWebPagePrerender — Fires just before a completed web page in the front end is sent to the browser, after all tags have been processed.
OnWebPageComplete — Fires just after a web page has been sent to the browser and the processed resource is saved to the cache.
Thats a helpful list - thanks
