is_page_template function breaks after the loop

    I’m changing between black and white images on different pages by using is_page_template(pagename.php) to set a string value to either _rvs (stands for reverse) or empty and then inserting the returned string into the image URL.

    Everything was working across several pages. If I add a post loop to my home page ‘front-page.php’ the correct string is passed to images above the loop but not to images beneath the loop. I read the codex relating to <?php wp_reset_query(); ?> and integrated it after the loop but it does not fix the problem.

    This is in my functions.php…

    // Set page styles
function reverse_styles() {
	$reverse = '_rvs';
	if ( !is_page_template('about.php') && !is_page_template('front-page.php') ) {
		$reverse = '_rvs';
	} else {
		$reverse = '';
	}
	return $reverse;
}

    I call the function in my page as follows…
    <img class="myClass" src="<?php echo get_stylesheet_directory_uri() ?>/images/imageName<?php echo reverse_styles() ?>.png" alt="" />

    The resulting URL in the browser is either .../images/imageName.png or .../images/imageName_rvs.png

    Any suggestions why it breaks after the loop?

  • Try changing !is_page_template('front-page.php') to !is_front_page(). I’m pretty sure that is_page_template only works with custom templates.

    Thanks, esmi that was quick. I printed<?php echo reverse_styles() ?>directly within the page above and beneath the loop and the returned string changes in the browser. No luck with !is_front_page() I’m afraid, if it makes any difference my Reading Settings are set to a static Front page referencing the template name of front-page.php which is “Home MySite”.

    Its very late here, I’ll have to look at it tomorrow. Thanks for the suggestion.

    Jeez, that was ridiculously difficult to solve and not documented anywhere in the codex. The solution, which I found by luck alone, is here.

    It *really* should be in the docs and that thread is two years old. Creating a new Query object instead of using $wp_query solved it. Calling is_front_page() is_page(pageName) or is_page_template('filename.php') will all fail if you use $wp_query as normal even if you reset it after the loop.
