Answered How to solve EventsX Url

We're using EventsX - not sure it's still supported but it looks a reasonably simple-to-use calendar plug in. The issue we're having is that the hyperlinks to the events from the calendar aren't working correctly. We're using Friendly URLs and the Event Page link which is output is calendarupcomingevents.htmlTest+Event/1. The EventsX event created is called Test Event and looking in the snippet we see

.

Just not sure what format EventsX is expecting $modx->makeUrl($eventsPage) to be in in order to append '/'.$event['id'];

Since posting, came across a couple of things:
https://docs.modx.com/extras/revo/eventsx says

4. Create a resource for the events calendar (or add it to your template(s))
5. Create a resource for the upcoming events list (see template example below)
6. Create a resource below that for a single event (see template example below)

See on '6' it says 'below that'. It means a child page of 5. Missed that.

We also came across a post from Wallaco from 3 years back:
https://forums.modx.com/thread/97779/onpagenotfound-not-firing-unless-debug-added-for-eventsx
Seems like the same issue. As mentioned there, URLs should be in the format:

Summary resource URL: http://domain.com/events/
Detail resource URL: http://domain.com/events/Some+Event/2

with the detail resource then using to forward the request URL and parameters to the single event page.

We found a couple of things. As the other post says, the plugin uses a OnPageNotFound.

works fine and spits out a calendar page.
After the 'if' comes an elseif for the events pages
This doesn't work and comes up with an error

PHP warning: preg_match(): Unknown modifier 'c'

If you override the elseif with a straight forward 'else'
that fires, but the 'Some+Event/2' get stripped from http://domain.com/events/Some+Event/2 link and you just end up seeing the resource URL: http://domain.com/events/

Any ideas, folks?

Can you post the code with the preg_match() error? The file and line number should be in the error message.

Just not sure what format EventsX is expecting $modx->makeUrl($eventsPage) to be in in order to append '/'.$event['id'];

You've already found the partial answer to that in the instruction #6, but that line expects your $eventsPage to be a resource container, so that the friendly url ends in / instead of .html

Hi Bob

Modx error log shows:


Line 62 being:

Checking server PHP version, it's old

PHP 5.5.9-1ubuntu4.22

Thanks

Did you see Mark Hamstra's answer? It looks promising to me.

The key may be the value of $eventsPageRegex. If it has an unescaped forward slash followed by the letter 'c', that would explain the error message you're getting.

Seen Mark's reply, good point, thanks. Did that when making resource '6' a child of '5' as in my 2nd post. No joy.

I wonder whether your comment on the other post 3 years ago might be the way to go, use some other method & just redirect to the event detail directly.

As a diagnostic, You might add this somewhere above the error line, but after the value of $eventsPageRegex is set:



Then check the error log for a value with a slash followed by the letter c.

Right. As I suggested, if the delimiter is a '/', any '/' characters in the pattern have to be escaped with a backslash so they won't be interpreted as the final delimiter. Changing the delimiter can also work, but you have to make sure that the character you use will never appear in the pattern, or escape it.

The fact that you still saw the preg_match() error means that the error-log code I suggested is not above the first bad preg_match() code. If it were, the error log would show the $eventsPageRegex value, which we now know contains '/c' since changing the delimiter solved things.
