This is a silly question, but I can't find the proper way to ask it to google. so, sorry if this is a repetitive question.
I give a custom field with a checked that the user can check if he want this specific post to go the home page. So in my home page, I call for all the post who has the checked activated.
I am creating my custom field for the custom post type CV:
function add_custom_post_meta_box() {
add_meta_box(
'custom_post_meta_box', // $id
'Campos Personalizados', // $title
'show_custom_post_meta_box', // $callback
'cv', // $screen
'normal', // $context
'high' // $priority
);
}
add_action( 'add_meta_boxes', 'add_custom_post_meta_box' );
But inside this custom post meta box, I have multiple fields, like a label and a checkbox:
function show_custom_post_meta_box() {
global $post;
$meta = get_post_meta( $post->ID, 'your_fields', true ); ?>
<p>
<label for="your_fields[text]">Especialidad</label>
<br>
<input type="text" name="your_fields[text]" id="your_fields[text]" class="regular-text" value="
<?php if (is_array($meta) && isset($meta['text'])){ echo $meta['text'];} ?>">
</p>
<p>
<label for="your_fields[checkbox]">Mostrar en Home
<input type="checkbox" name="your_fields[checkbox]" value="checkbox"
<?php
if (is_array($meta) && isset($meta['checkbox'])){
if ( $meta['checkbox'] === 'checkbox' ) echo 'checked';
}
?>>
</label>
</p>
Okey, the rest of the code save the custom field and works perfectly. My problem is when I try to call it:
$posts = get_posts(array(
'posts_per_page' => -1,
'post_type' => 'cv'
// 'meta_key' => 'your_fields[checkbox]', //This is wrong!!
// 'meta_value' => 'checkbox'
));
And when I try to call the post info:
<?php
foreach( $posts as $post ):
setup_postdata( $post );
?>
<h2><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2>
<p>
<?php
$meta = get_post_meta( $post->ID, 'your_fields', true );
if (isset($meta['checkbox'])){
echo $meta['checkbox'];
}
?>
</p>
<?php endforeach; ?>
So, my question is: How can make my query, to bring me just the custom post types, with a checked activated.

Reset to default 1If you want to use post meta for setting which posts are displayd on the front page, then I would recommend saving the setting with a separate meta_key. So instead of pushing it to the your_fields save it with its own key.
This means modifying your metabox content to have something like this,
<input type="checkbox" name="show_on_front_page" value="true"
Please modifiy your metabox saving box also accordingly.
Then you should be able to use the get_posts like so,
$posts = get_posts(array(
'posts_per_page' => -1,
'post_type' => 'cv',
'meta_key' => 'show_on_front_page',
'meta_value' => 'true'
));
But just yesterday I saw a comment by Mr. Tom J Nowell on some other thread, that this is rather inefficient way of setting front page posts. On a larger site this could, in the worst case scenario, grind your site's server to a halt.
You would be better off using a (private) custom taxonomy to which you would assign posts you want to show on the front page. Getting posts with a certain taxonomy from the database is faster and more efficient way of doing things.
From Mr. Nowell's blog, https://tomjn/2018/03/16/utility-taxonomies/
Set up custom taxonomy,
function tomjn_utility_taxonomy() {
$args = array(
'label' => __( 'Internal Markers', 'tomjn' ),
'public' => false,
'rewrite' => false,
'show_ui' => true, // you'd need this if you want to show the taxonomy metabox on the post edit screen
);
register_taxonomy( 'utility', 'post', $args );
}
add_action( 'init', 'tomjn_utility_taxonomy', 0 );
Automate publishing to front page,
function tomjn_auto_add_to_home( $post_id ) {
wp_set_object_terms( $post_id, 'show_on_homepage', 'utility', true );
}
add_action( 'publish_post', 'tomjn_auto_add_to_home' );
adjust the homepage query
function tomjn_only_show_home( $query ) {
if ( $query->is_home() && $query->is_main_query() ) {
$query->set( 'utility', 'show_on_homepage' );
}
}
add_action( 'pre_get_posts', 'tomjn_only_show_home' );
Please refer to the blog post for more detailed explanation.
