如果 (is_page_template()) 在 header.php 中不起作用

Question

I have 3 separate header options, all with a banner image: 1. Homepage 2. Sponsor Template 3. All other pages.

I have placed the below code in the header. The homepage and all other pages are working as expected, but I can't seem to make the Sponsor template work (the class="sponsor-title" is not appearing).

<?php if ( has_post_thumbnail()) : ?>
    <?php the_post_thumbnail(); ?>
<?php endif; ?>
<?php if ( is_front_page()): ?>
    <span class="home"><h1><?php echo event_title(); ?></h1></span>
    <span class="tag-line"><?php the_field('tag_line'); ?></span>
    <span class="date"><?php the_field('date_time_header'); ?></span>
    <?php 
        $ticket = get_field('ticket_url');
        if ( $ticket ): 
            $ticket_url = $ticket['url'];
            $ticket_title = $ticket['title'];
        ?>
        <a class="button" href="<?php echo esc_url($ticket_url); ?>"><?php echo esc_html($ticket_title); ?></a>
<?php if (!is_page_template('page-templates/all-sponsor-template.php')); ?>
    <span class="sponsor-title"><h1><?php echo event_title(); ?></h1></span>
<?php endif; ?>
<?php else: ?>
    <span class="page-title"><h1><?php the_field('page_header'); ?></h1></span>
    <span class="sub-header"><?php the_field('sub_header'); ?></span>
<?php endif;?> 

What have I done wrong? I want to ensure that when the template or page is chosen that the correct styling appears, as it is very different from the other pages.

<?php if (!is_page_template('page-templates/all-sponsor-template.php')); ?>
    // Stuff
<?php endif; ?>

Here you are checking if the page template is NOT page-templates/all-sponsor-template.php , and if it isn't - then you show the sponsor title...

I might be confused, but shouldn't it be like this?

<?php if (is_page_template('page-templates/all-sponsor-template.php')); ?>
    // Stuff
<?php endif; ?>

Ie swapping the if condition so that the sponsor title shows if the page template IS the mentioned file.

Edit: The if statement that checks if the sponsor page template is being used, is inside the if statement that checks if the current page is the home page.

If you move the template check one level up, it should do the trick:

<?php if ( has_post_thumbnail()) : ?>
    <?php the_post_thumbnail(); ?>
<?php endif; ?>

<?php if ( is_front_page()): ?>
    <span class="home"><h1><?php echo event_title(); ?></h1></span>
    <span class="tag-line"><?php the_field('tag_line'); ?></span>
    <span class="date"><?php the_field('date_time_header'); ?></span>

    <?php 
    $ticket = get_field('ticket_url');
    if ( $ticket ): 
    $ticket_url = $ticket['url'];
    $ticket_title = $ticket['title'];
    ?>
    <a class="button" href="<?php echo esc_url($ticket_url); ?>"><?php echo esc_html($ticket_title); ?></a>
<?php endif; ?>

<?php if (is_page_template('page-templates/all-sponsor-template.php')); ?>
    <span class="sponsor-title"><h1><?php echo event_title(); ?></h1></span>
<?php endif; ?>

<?php else: ?>
    <span class="page-title"><h1><?php the_field('page_header'); ?></h1></span>
    <span class="sub-header"><?php the_field('sub_header'); ?></span>
<?php endif;?> 

This way it will check if the sponsor template is being used on all pages and not only when on the home page.

Your problem is the syntax of your if statement. Try this instead:

<?php if (!is_page_template('page-templates/all-sponsor-template.php')) { ?>
<span class="sponsor-title"><h1><?php echo event_title(); ?></h1></span>
<?php } else { ?>
<span class="page-title"><h1><?php the_field('page_header'); ?></h1></span>
<span class="sub-header"><?php the_field('sub_header'); ?></span>
<?php } ?>

I always use the {..} brackets, as it's easier to follow and understand the logic of the code. However, to rewrite your code using the correct structure of the if statement you've attempted, it would look like this:

<?php if (!is_page_template('page-templates/all-sponsor-template.php')): ?>
<span class="sponsor-title"><h1><?php echo event_title(); ?></h1></span>
<?php else: ?>
<span class="page-title"><h1><?php the_field('page_header'); ?></h1></span>
<span class="sub-header"><?php the_field('sub_header'); ?></span>
<?php endif; ?>

And, of course, the exclamation mark here:

if (!is_page_template('page-templates/all-sponsor-template.php'))

means "If NOT page template all-sponsor-template.php" so remove it if you are checking for TRUE.

Finally, keep in mind that due to certain global variables being overwritten during The Loop, is_page_template() will not work in The Loop. However, if this code is in your header.php , then you should be fine.
