Problem: I have 3 post types in a child -> parent -> grandparent hierarchy relationship. I would like to display information about the parent and grandparent in the child post.
Solution:
Access information about a parent post, you can use the following syntax:
[wpv-post-title id="$parent-type-slug"]
So for example, if your city post type slug is "city", then your code will be:
[wpv-post-title id="$city"]
To access information about a grandparent post, you can use a Content Template to change the context by passing in the $city operator for the id attribute:
Inside that Content Template, you can then use the parent post technique we used before to access the grandparent country post. If your country post type slug is "country" then your code in the Content Template will be:
Problem: I would like to show custom field images at different sizes depending on their file extension.
Solution: There's not an easy way to do this in Toolset, so you must add a custom shortcode to functions.php:
// return the extension of a custom file URL (everything after last ".")
add_shortcode( 'get_file_ext', 'get_file_ext_func');
function get_file_ext_func($atts)
{
$urls = $atts['file_url'];
$fileparts = explode('.', $urls);
return end($fileparts);
}
Next, register this shortcode to be used as a 3rd party shortcode argument by going to Toolset > Settings > Front-end content and typing "get_file_ext" in the 3rd party shortcode arguments area.
Then you can use the shortcode do build a conditional:
