Home Template Loop customization - should fetch content based on post template - php

Question

In the theme there are two files:
single.php
f-template.php → For default post type. It has different designs.
Home.php will fetch first 10 posts, and they can be among any of the above templates.
But, what is needed is when the content on home.php is coming from f-template.php
then these two things should be implemented on home.php
function folder_paragrapgh($content){
return preg_replace('/<p([^>]+)?>/', '<p class="para para2">', $content);
}
add_filter('the_content', 'folder_paragrapgh');
and
<script>
(function($) {
// do all your $ based jquery in here.
$(function() {
$('p.class2').prepend('<img src="http:/sample.com/img/folder.svg" width="50" height="25" alt="">');
});
})(jQuery);
</script>
I tried this:
if( is_page_template( 'f-template.php' ) ) {
function folder_paragrapgh($content){
return preg_replace('/<p([^>]+)?>/', '<p class="para para2">', $content);
}
add_filter('the_content', 'folder_paragrapgh');
}
the_content();
}
But this didn't work. actually it is flawed because the template that we are dealing is home.php.
So do we have any solution to achive what we wanted to achieve?

Answer 1

Correct me if I'm wrong but it sounds like you want to display a loop with posts where some posts have a different design depending on the Page Template you have selected for it.
You can check which template is being used with the get_page_template_slug() function. Use it inside the loop along with the ID of the post.
// checks if there are any posts that match the query
if (have_posts()) :
// If there are posts matching the query then start the loop
while ( have_posts() ) : the_post();
// Assign postId from within the loop
$postId = the_ID();
if( get_page_template_slug($postId) === 'f-template' ) {
// Display what you want to see when f-template is selected.
} else {
// Display what you want to see by default if no condition is met.
}
// Stop the loop when all posts are displayed
endwhile;
// If no posts were found
else :
echo '<p>Sorry no posts matched your criteria.</p>';
endif;
The is_page_template() function won't work because it will check what the page template for the current page in the Main Query is.
It all depends on your use case but personally I would have added an extra field using Advanced Custom Fields for this effect.
Good luck!
