Conditional template based on shortcode

    Hello everyone! I’ve tried to piece together what I’m looking to do, but I’m not finding the detail in the WP documentation or from any Google/Stack Overflow searches that is helping me achieve my end goal, so I’m turning here for some guidance.

    Here’s the deal: I have the PHP below in my functions.php, which I use to load an alternate single.php when the querystring mode=test is present in the URL.

    function alt_add_query_vars($vars) { return array(‘mode’) + $vars; }
    add_filter(‘query_vars’, ‘alt_add_query_vars’);

    function alt_template($template) {
    global $wp;
    if ( ($wp->query_vars[‘mode’]==’test’) ) { return dirname( __FILE__ ) . ‘/single-test.php’; }
    else { return $template; }
    }
    add_filter(‘single_template’, ‘alt_template’);

    I’d like to adapt it so that it will ALSO load the alternate template if a [test] shortcode is present in the post (the shortcode is already registered in functions.php and works fine). I attempted to add an OR condition to the if, looking for either the querystring OR the shortcode, but it is not proving successful:

    strstr( $post->post_content, '[test' )

    If anyone has done something similar or has thoughts on how to achieve this, I’d be very interested in learning.

    As is pretty much always how it goes, I figure it out moments after I ask for help. Anyway, in case anyone is interested, here’s my solution:

    Start with an additional function inside function.php

    function has_custom_shortcode($shortcode = '') {
    $post_to_check = get_post(get_the_ID());
    $found = false;
    if (!$shortcode) { return $found; }
    if ( stripos($post_to_check->post_content, '[' . $shortcode) !== false ) { $found = true; }
    return $found;
}

    (Adapted from something I saw here.)

    Then, I was able to simply leverage the function in my OR condition:

    if (has_custom_shortcode('test') === true)

    That’s all it takes.
