PHP error “Array to string conversion”

To figure out what’s causing this error you need to temporarily modify wp-content/plugins/events-manager/classes/em-calendar.php

Make a backup copy of em-calendar.php and then change line 494 from this:

if( is_array($value) ) $value = implode(',', $value);

To this:

if ( is_array( $value ) ) {
  foreach ( $value as $el ) {
    if (is_array($el)) {
      error_log('$arg[' . $name . '] contains an array element. The value is:' . print_r( $value, true ) );
      break;
    }
  }
  $value = implode(',', $value);
}

Then post the new error output here.

The function EM_Calendar::output is getting called with a $args array and it has an entry $args[‘style’] which is equal to array([background_image_attachment => “”, background_display=> “tile”)

This doesn’t seem to be coming from the Events Manager plugin. Are you using Events Manager Pro? Looks like this error comes when displaying the Events Calendar Widget. Are then any url parameters when dispaying the page? Is there some way to specify the background style when adding widgets in your theme?

You could try the following code snippet to fix this problem:

add_filter('em_widget_calendar_get_args', function( $args ) {
    if ( is_array( $args ) && array_key_exists( 'style', $args ) {
        unset( $args['style'] );
    }
    return $args;
});

You can use the Code Snippets plugin to add this code snippet.

Try modifying the code snippet to this:

add_filter('em_calendar_get_args', function( $args ) {
    if ( is_array( $args ) && array_key_exists( 'style', $args ) {
        unset( $args['style'] );
    }
    return $args;
});

There was no syntax error in my code snippet:

You must have made a mistake when copying and pasting the code snippet. Make sure you copy the code snippet from the code block in this thread (not from the email).

The error must have occurred when you copied the code snippet. I copied and pasted my code snippet and I didn’t get any syntax error.
