I am totally new to wordpress and acf and I'm trying to use a user field in a post to show the author of the post. I tried to programatically add the post author id as a meta attribute in the wp_postmeta table like this:
update_field('video_author', get_current_user_id(), $post_id);
The post author, however, is not shown:
What am I doing wrong?
Also when I click the user field no users are listed. I presume acf looks for users in either "wp_users" or "users" table, both of which contain records. However, this is shown:
Thank you in advance.
When you inspect element your field , you will find key like field_59c383916102a
update_field( 'field_59c383916102a', get_current_user_id(), $post_id );
//Replace field_59c383916102a with your key value

As several fields are updated programmatically, I want those not to be updated when a post is saved or updated inside the wp-admin dashboard.
For example, the ACF repeater field named tickets must not be saved during backend editing and when the post is saved or updated (because entries that are added programmatically during the time the post is edited are deleted when saved).
My idea: Before a post is updated, save values of tickets right before that post is saved using acf/save_post before save and then update_field() using acf/save_post again after save.
I know that you rightfully ask for the own approaches and attempts at solutions. Unfortunately, I don't have any. I have no idea how to combine these two acf/save_post correctly. If this is the right approach at all. That's why I would be all the more grateful for your help and support.
Thank you so much!
I had a scenario similar to this where I didn't want users to be able to manually update fields. I created a function that would let me use an ACF filter to disable the specific fields. It looked like this:
function vgs_set_acf_fields_to_disabled( $field ) {
global $post;
if ( isset( $post ) ) {
$field['disabled'] = 1;
}
return $field;
}
add_filter( 'acf/load_field/name=tickets', 'vgs_set_acf_fields_to_disabled' );
Then, if you have more fields, you can add more add_filter lines and simply update the name variable to match your ACF field name.
Maybe this will work for you as well?
I have custom meta box with multiple fields and it is working fine. Now, I want to store this meta box data into a custom table. So how can I do that ?
I have researched on google and Youtube but didn't got what exactly I am looking for.
If anyone can provide me with Step by Step guide or tutorial links then it will be very much helpful.
I'm not entirely sure why you would want to store Post Meta into a separate table, but I've had situations where I've needed to do crazier things.
The gist would be that you can use your Custom Meta Box to display the form fields, and then handle those form fields with your own custom function on the save_post hook.
Let's say you've registered a custom meta box with <input name="my_custom_table_field" /> in it. Instead of using update_post_meta() on the save_post hooks, you could write a function that manages the data with the $wpdb->update method. Something like this would get you started:
add_action( 'save_post', 'save_my_custom_data' );
function save_my_custom_data( $post_id ){
global $wpdb;
if( isset( $_POST['my_custom_table_field'] ){
$result = $wpdb->update(
'my_custom_table',
array(
'post_id' => $post_id,
'my_custom_table_field' => $_POST['my_custom_table_field'],
),
array(
'post_id' => $post_id
),
array(
'%d',
'%s'
),
array (
'%d'
)
);
});
}
You'll want to make sure to handle the data appropriately before saving it, of course. And again, I'm not sure why you'd need a custom "meta" table, but farbeit from me to say you "shouldn't" (especially depending on your particular usecase) - but something like the above would get you started.
To summarize:
Display your custom meta box with WP's metabox functions
Handle the save_post hook for your custom fields separately
Sanitize, trim, or otherwise make sure the data being stored is supposed to be stored in accordance to best practices for the field type
Make use of the global $wpdb class to update it.
Also of note, this answer doesn't go into CREATING the database table - because that depends on your storage engine, particular indexing needs, etc. But in general you should be able to search for "create database table in [whatever storage language]" to get a walkthrough of creating the table - then use the outline above to store the data in it.
This is the official Wordpress guide: https://developer.wordpress.org/plugins/metadata/custom-meta-boxes/
I want to change the name of a custom post type after I'm using it for a long time.
The current name is registered like this:
register_post_type( 'toremove-name' , $args );
And I want it this way:
register_post_type( 'name' , $args );
If I change it, I think it will make problems in the DB.
Is there a way or a plugin to solve this?
I'm sure there is a plugin, but if you have MySQL access, you can also just rename the CPT the way you have indicated and perform am SQL query to update:
UPDATE wp_posts SET post_type = New CPT Name WHERE post_type = Old CPT Name;
Also, don't forget your taxonomies if you have any registered to the CPT. You might have to flush your permalinks after you performed this action
I can't figure out with this problem: when woocommerce sends the order processing mail to custumer, customer's meta properties are valorized in the $order object, and the valorization is done by the execution of the action woocommerce_email_order_meta (at least, I suppose):
do_action( 'woocommerce_email_order_meta', $order, $sent_to_admin, $plain_text );
All fine with that, but when I want to create a custom template for that email, no meta values will be displayed in the result, although the same invokation.
I've checked the parameter values passed to the "woocommerce_email_order_meta" invokation (that routes to the order_meta() function in plugins/woocommerce/includes/class-wc-emails.php) of my costum template, and those values are the same.
Neither debugging the order_meta() function in both cases gave me clues, the function's behavior is always the same, but the result in the mail is different. So... what can I do for insert order meta info in this mail?
Sorry if this question is a duplicate and for my bad english.
Thanks in advance if you can help me with this issue.
Billing address and other details, such as first name and last name are stored as order details (In "postmeta" table). Whereas, Products in the order, its quantity, price is stored as Order meta.
Therefore, "woocommerce_email_order_meta" action will display order meta details.
Please make sure, you have included the below line, in your custom email template to get Billing address and other details.
<?php wc_get_template( 'emails/email-addresses.php', array( 'order' => $order ) ); ?>

I have noticed that the list of users generated by users.php in my dashboard doesn't take into account custom post types when it displays the number of posts by each user.
So even if a user has 20 posts of a custom post type, it will still show '0' next to their name.
Does anyone know how to resolve this and add custom post types to this number?
For anyone else looking to achieve the same, I managed to resolve it using this solution...
function my_manage_users_columns($columns) {
$columns['post_type_count'] = __( 'Books', 'textdomain' );
return $columns;
}
add_filter('manage_users_columns', 'my_manage_users_columns');
With 'Books' being the name of the custom field
