Filter custom fields using EM_Events:get

Hi,

Glad you’re enjoying the plugin.

What do you mean when you say, “But that completely ignores my Event_attributes stuff”. You mean it ignores custom attributes / fields you’ve added using Events Manager?

It just lists all of events and ignores the “publish_to_university_homepage =>1” attribute i have in my get() request.

Keep in mind, I added this custom field using Advanced Custom Fields (ACF), and NOT the events Manager custom fields. I did this because it made it easier with the other fields I have for posts. Do I need to use the Events Manager custom fields? If so, how would I form the get requests in this case? And can I apply the same custom fields across my whole multisite network?

Thanks

maybe you can try additional coding like

if ( in_array('news',$featured_events->event_attributes) ){ 

}else{

}

You mean grab a couple of events and then filter through them with this kind of if statement?

That would be sort inconvenient, because I wont know how many posts to grab before finding what i need.

Thanks

I think Angelo means you’d just use that code in an if statement to discard, or keep, the events you wanted.

Right thats what I understood too? But I’m saying that wouldn’t be very efficient. Do you have any recommendations on how I should do my search? Should I just go day by day until i have the number of events I want?

I am trying to do what Angelo_nwl suggested. However, I don’t know how to parse

[event_attributes] => a:1:{s:30:"publish_to_university_homepage";s:1:"0";}

Which is what is in my EM_Events array. PHP thinks its a string, so I can’t use in_array…

Any ideas?

you can use php serialize() – https://www.php.net/manual/en/function.serialize.php

eg.

$event_attributes = serialize ($featured_events->event_attributes);
if ( in_array('news',$event_attributes) ){ 

}else{

}

@angelo_nwl I did that but in_array complains that its still a string. So I’m guessing it was able to serialize?

I mean, this doesnt look very normal to me:
[event_attributes] => a:1:{s:30:”publish_to_university_homepage”;s:1:”0″;}

Where are you using that code? I think it would be helpful to see the chunk of code you’re using.

function getEventsWithFilter($limit, $conditions, $blog = ""){
	$grab = 5;
	$offset = 0;
	$events = [];
    while(count($events) < $limit){
    	$tempEvents = EM_Events::get( array('limit' => $grab,
    										'offset'=> $offset,
    										'blog' => $blog,
    										'array'=> true));
    	if(count($tempEvents) == 0)
    		break;//no more events to save
    	//print_r($tempEvents);
    	foreach($tempEvents as $tempEvent){
    		$EA = serialize($tempEvent['event_attributes']);
    		print_r($EA);
    		if($EA){
    			foreach($conditions as $condition){
    				//echo $condition;
    				if(in_array("publish_to_university_homepage", $EA))
        				array_push($events, $tempEvent);
        		}
        	}
        }
        $offset += $grab;
    }

    //Trim off extra arrays, since we do 2 at a time
    return array_slice($events, 0, $limit);
}

This gives me this error on the in_array line:

Warning: in_array() expects parameter 2 to be array, string given in

Also the print_r, clearly looks like an string.

Does that help? Thanks

you need

$tempEvents->event_attributes

instead of

$tempEvent['event_attributes']

Yes I have tested that too.

function getEventsWithFilter($limit, $conditions, $blog = ""){
	$grab = 5;
	$offset = 0;
	$events = [];
    while(count($events) < $limit){
    	$tempEvents = EM_Events::get( array('limit' => $grab,
    										'offset'=> $offset,
    										'blog' => $blog,
    										'array'=> true));
    	if(count($tempEvents) == 0)
    		break;//no more events to save
    	//print_r($tempEvents);
    	foreach($tempEvents as $tempEvent){
    		$EA = serialize($tempEvent->event_attributes);
    		print_r($EA);
    		if($EA){
    			foreach($conditions as $condition){
    				//echo $condition;
    				if(in_array("publish_to_university_homepage", $EA))
        				array_push($events, $tempEvent);
        		}
        	}
        }
        $offset += $grab;
    }

    //Trim off extra arrays, since we do 2 at a time
    return array_slice($events, 0, $limit);
}

Gives this as output (repeated multiple times):

N;
Warning: in_array() expects parameter 2 to be array, string given in /Users/thegreyspot/Workroom/wnmu/wp-content/themes/wnmu/lib/custom.php on line 166

What are you getting for print_r($EA); ?

Thats what the “N;” is… no idea what that means! haha
