“Issues” loading MANY featured images on a single page (custom template)

Calling an image within the theme folder from inside a post/page?

I realize that this was posted about 7 months ago, but in case you’re still looking for a solution to this, add this to your functions.php file: /** * Add a shortcode for the current theme directory * @return string Current theme directory */ function yourtheme_get_theme_directory_uri() { return get_template_directory_uri(); } add_shortcode( ‘themeuri’, ‘yourtheme_get_theme_directory_uri’ ); Then … Read more

Change location of header.php and footer.php

It is not possible to override header/footer via hooks in respective get_header()/get_header() functions. However it is often overlooked that these function allow input and loading different headers. For example get_header( ‘nested/header’ ); will look for header-nested/header.php in theme’s folder. It’s kind of a hack in regards to subdirectory use, but it works. 🙂

So let’s say that somewhere in your template is: <?php while ( have_posts() ) : the_post(); ?> <article> … SOME CODE <?php while ( have_rows( ‘YOUR_FIELD_NAME’ ) ) : the_row(); ?> … Read more

Global variable set in the template’s header.php is unable to echo in footer.php

All I need was to use global variable before the declaration AND before echoing. <?php global $postidextra; $postidextra = “20”; ?> and then <?php global $postidextra; echo $postidextra; ?> Thanks G.M. for the idea.

get_template_part returns NULL

As the codex page of get_template_part() says: get_template_part doesn’t return a value and doesn’t warn if it fails to find a matching template file. Additionally: If you want to hear about failures, use: <?php assert( “locate_template( array(‘$name-$slug.php’, ‘$name.php’), true, false )” ); ?> So no wonder you are get nothing back. One thing I’m seeing … Read more
