22110	Check for current conditional	mintindeed		"More than once I've needed a programmatic way to determine what page is being displayed, for example when implementing event tracking recently:


{{{
add_action( 'wp_enqueue_scripts', function() {
	wp_enqueue_script( 'my-site', get_template_directory_uri() . '/js/mysite.js', array( 'jquery' ), '1', true );

	// Figure out what type of page we're on
	$is = '';
	foreach ( $GLOBALS['wp_query'] as $key => $value ) {
		if ( true === $value && 'is_' === substr( $key, 0, 3 ) ) {
			$is = substr( $key, 3, strlen($key) );
			break;
		}
	}
	wp_localize_script( 'my-site', 'event_tracking', array(
		'category' => $is,
	) );
} );

}}}
And then used like:

{{{
<a onclick=""_gaq.push(['_trackEvent', event_tracking.category, 'more-stories', 'click']);"">Action</a>
}}}

Now granted the above way to determine the current page is a little janky, and has at least one flaw (on custom post type archives because both ""is_archive"" and ""is_post_type_archive"" are set, and it will find ""is_archive"" first, every time).  TBH this was me with a bowl of chili in one hand trying to avoid typing out ""if ( is_* ) { } elseif ( is_* ) { } elseif ( is_* ) {} ..."".  

A saner function would probably explicitly check each conditional, which would make it a little more tedious but also more maintainable:

{{{
function where_am_i( $return = 'simple' ) {
	global $wp_query;
	
	if ( ! isset( $wp_query ) ) {
		_doing_it_wrong( __FUNCTION__, __( 'Conditional query tags do not work before the query is run. Before then, they always return false.' ), '3.5' );
		return false;
	}
	
	$primary = null;
	$secondary = null;
	$tertiary = null;
	
	// Tried to maintain the hierarchy from query.php
	if ( true === $wp_query->is_robots ) {
		$primary = 'robots';

	}
	
	if ( 'detailed' === $return ) {

		return $details;
	}
	
	// 'simple' === $return
	return $primary;
}
}}}

Should it use $wp_the_query so that it always acts on the main query?  "	enhancement	new	normal	Awaiting Review	General	3.4	normal
