Alt Text for Images and Deleting old images

[James]

I have noticed that when I used the Events Aggregator, the images which are pulled from other place into the website have no Alt Text, or Captions with them. Can this have some default settings so it mirrors the title of the event?

ALSO, when events are over, Is there an easy way to delete all of the left left over events, AND more importantly, space grabbing graphics?

Hi James,

What might make more sense here (rather than target Event Aggregator specifically) is an approach that provides default attributes when necessary for featured event images generally.

The tribe_event_featured_image hook provides an opportunity to do this:

add_filter( 'tribe_event_featured_image', function( $html, $event_id ) {
	$img_start = strpos( $html, '<img ' );
	$img_end   = strpos( $html, '/>', $img_start );
	$img_len   = $img_end + 2 - $img_start;

	if ( ! $img_start || ! $img_end ) {
		return $html;
	}

	$img = substr( $html, $img_start, $img_len );

	// Add an alt tag if it does not already have one
	if ( false !== strpos( $img, 'alt="' ) ) {
		$title = esc_attr( get_the_title( $event_id ) );
		$img   = substr_replace( $img, 'alt="' . $title . '" ', 5, 0 );
		$html  = substr_replace( $html, $img, $img_start, $img_len );
	}

	return $html;
}, 10, 2 );

The above shows one way of doing this that doesn’t assume any additional PHP extensions are installed and adds an alt tag if it is missing.

Adding captions or title attributes (for native ‘tooltips’) could be implemented using a similar approach. Does this help – or at least give you a starting point – with the first part of your question?
