What I want
On my front-page is a section ( <div class="m-rowteaser m-rowteaser--default"> ) what is displaying a random post from the post-type projects.
There are some post that I don’t want to see at the front-page.
Note: the post must be active because there is another page with these post.
In my backend I have a custom field where I want to select if it is displayed at the front page.
The way you can help me
- give me an idea how a solution could be
- give me an documentation about it
- give me a code snippet
- if you need something from me to help me leave a comment there.
- please don’t hate me if I have some problems… I work for a short time now with code….
Thank you for helping me!!!! :))))
Update
Now I have a function that can hide post from the front-page by the id. I need help to connect this code with the custom field in the backend.
<?php
function wpb_exclude_from_home($query) {
if ($query->is_home() ) {
$query->set('post__not_in', array(134, 122,));
}
}
add_action('pre_get_posts', 'wpb_exclude_from_home');

Answer
You can use the meta_query field to only show projects where _projects_show is set to yes (assuming that’s the field you want to use, feel free to adjust the code below where needed):
$loop = new WP_Query( array(
'post_type' => 'projects',
'orderby' => 'rand',
'posts_per_page' => 1,
'meta_query' => array(
array(
'key' => '_projects_show',
'value' => 'yes',
'compare' => '==',
),
),
));
