[jgen] check for file exists when user opens plugin params

[Russ Winter]

I'm trying to find a way to check for the existance of a file or folder and post a message to the plugin configuration page.

I am already doing this at installation and update in the script.php with JFolder::exists and JFile::exists to actually complete the check and test for true/false but I can't seem to workout how to do the same thing and post an error message back to the plugin params page when the user opens it to configure options.

Any pointers would be helpful and appreciated.

thanks a lot,

Russ

You'd probably need to use the `onContentPrepareForm` event since the admin views don't dispatch events the same way the frontend does.

thanks Michael,

I was trying a variety of events to no-avail and hadn't come across that on in my research on the docs-wiki. Will give it a go

Cheers

it might just be me mis-using it and my lack of knowledge with plugin architecture, but still no joy, maybe it's just not possible from a plugins params view in Admin. I certainly don't know of any plagins I use that post additional messages on viewing the xml params.

I just thought it was a good "feature/function" to check that extension that my plugin is used with was still installed and if not, post a message or automagically disable the plugin if I didn't find the related component and in this particular case; if the params view didn't find an override that is installed with the plugin.

I was just trying to catch if the user installed my plugin, then either un-installed the component or changed templates (hence the override was now not present under the new /templates/<templatename>/html/com_component 

I guess it's not hugely important, just a "nice to have"

Thanks for the suggestion anyway Michael

Create your own field type that you're installing with your plugin. Include the type and path to the type in your xml and in the type do your checks.
