I would like to have a function in my function.php that will run after deleting a child post
I know how to calculate the parent post but not sure how to call the calculation after the child post was deleted and run the update calculation on the parent.
Hello. Thank you for contacting the Toolset support.
Well - It seems to be not logical to count parent posts when you delete any child post as you are actually deleting child post and it will not have any effect on parent post count.
Did I misunderstand you? If yes: could you please share more details about your issue.
yes, you are right with your statement however you misunderstood my scenario so I will try to explain again.
I have a custom parent post type called 'total educations cost'
each parent can have many custom child post called 'education'
when I create the child custom post I sum a few values from all child's that belong to the parent and populate the parent post with the values. think of it as child education cost as follow:
child 1 - $1,000
child2 - $1,500
Parent post cost sum will be $2,500
I know how to do it, and I have a function in my function.php that do it and its working just fine.
the issue is when I want to delete a child (in the front end), which I can do using the cred_delete_post_link shortcode, is that the parent values are staying the same as if the child I deleted was never deleted. this is normal and expected as nothing was updating the parent post (recalculation).
so, what I need is a way to recalculate the parent post values when a child post was deleted. or in other words call a function that will calculate the parent when a child was deleted.
I hope this is more clear about my scenario.
Thanks,
Ok I got it. You would like to update the parent post calculation.
Well - you should use the hook 'post_updated' and check if "post_status" changed to trash and if deleted post belongs to your child post type 'education' , then run your code.
For example:
function func_update_prent_post_value($post_ID, $post_after, $post_before){
if($post_after->post_status == 'trash' and $post_before->post_type=='education'){
// find your parent post ID based on $post_ID and update the parent field value as required
}
}
add_action( 'post_updated', 'func_update_prent_post_value', 10, 3 );
If I use delete in the shortcode this will permanently delete the post and the code above might not catch it. correct?
do I have to use 'trash' in the delete short code in order to make the code sample above work?
function update_edu_prent_educhld_del($post_ID, $post_after, $post_before){
if($post_after->post_status == 'trash' and $post_before->post_type=='education'){
//Parent Post ID
$edu_parnt_id = wpcf_pr_post_get_belongs( get_the_ID(), 'education-parent' );
// get all education child posts related to the parnet
$edu_chld_posts = get_posts(array(
'numberposts' => -1,
'post_type' => 'education',
'post_status' => 'publish',
'meta_query' => array(array('key' => '_wpcf_belongs_education-parent_id', 'value' => $edu_parnt_id))
)
);
//if it returns some education posts
if( $edu_chld_posts ){
//get the single education posts fields values
foreach( $edu_chld_posts as $edu_single_post ){
//get each education post data
$sngl_edu_data = get_post($edu_single_post);
//get each ID
$sngl_edu_id = $sngl_edu_data->ID;
//get each posts field value
$sngl_edu_ttlcost_value = get_post_meta($sngl_edu_id, 'wpcf-total-education-cost', true);
//Sum the values all posts fields
$edu_totl_cost_sum+= $sngl_edu_ttlcost_value;
}
}
update_post_meta($edu_parnt_id, 'wpcf-sum-all-edu-plns-cst', $edu_totl_cost_sum);
}
}
add_action( 'post_updated', 'update_edu_prent_educhld_del', 10, 3 );
}
I also tried with the following way to get the parent id with no success.
Could you please share problem URL where I can see delete post link you added and few test posts to delete.
*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I would additionally need your permission to de- and re-activate Plugins and the Theme, and to change configurations on the site. This is also a reason the backup is really important. If you agree to this, please use the form fields I have enabled below to provide temporary access details (wp-admin and FTP).
I have set the next reply to private which means only you and I have access to it.
Hi Minesh,
I have moved custom code to the theme function.php.
FTP note: please dont use a folder name in the ftp link. the folder name is a mandatory field in toolset so I wrote root folder but you dont need it so the ftp is the domain name I provided (including the subdomain name)...
