Posts in multiple Categories different single.php

Question

I am smashing my head against some code. Here is the situation: I have one post in 3 different categories, this post has to be visible in "category 1" with the single1.php, in "category 2" with single2.php and in "category 3" with single3.php.

Obviously the 3 single.php pages have a different template inside. For example the single1.php shows pictures and the_content(); single2.php shows pictures and comments; single3.php shows the reviews.

I know that in single.php I can use the if/else but I cannot figure out if the same post is in 3 different categories.

Any help please?

Answer 1

Instead of making it category specific you could use post formats and use different content-templates. In single.php you can write

<?php get_template_part( 'content', get_post_format() ); ?>

Then create different post formats

add_theme_support( 'post-formats', array( 'withpictures', 'withcomments' ) );

Then create different post templates content-withpictures.php, content-withcomments.php

When creating content the chosen post format will determine the template.

You can use the filter hook for 'single_template'. Create single-cat1.php, single-cat2.php and single-cat3.php (cat1, cat2 and cat3 are the category names should be replaced by your category names)

function template_change( $template ){
    if( is_single() && in_category('cat1') ){
        $templates = array("single-cat1.php");
    } elseif( is_single() && in_category('cat2') ){
        $templates = array("single-cat2.php");
    } elseif( is_single() && in_category('cat3') ){
        $templates = array("single-cat3.php");
    }
    $template = locate_template( $templates );
    return $template;
}
add_filter( 'single_template', 'template_change' ); //'template_include'/'single_template'

You can change it on header.php if template using single-cat1.php, header.php must change style sheet Ex:

<link rel="stylesheet" type="text/css" href="<?php bloginfo('template_url'); ?>/ca1.css">
