Hi,
I had followed your recommendation at https://toolset.com/forums/topic/limiting-cred-form-submission-to-one-post/#
I have a CRED form (ID: 1695) which creates CPT Reviews (review) of another parent CPT Shops (shop) and I want to limit the number of reviews each user on my site submits, down to one review per shop.
The user roles are as follows:
Role 1: Author
Role 2: Contributor
Role 3: Editor
and I would like to show the same error message.
This code was my poor attempt, can you help? Thanks
//Limit the number of reviews for a user
add_filter('cred_form_validate','my_validation',10,2);
function my_validation($field_data, $form_data)
{
//field data are field values and errors
list($fields,$errors)=$field_data;
//uncomment this if you want to print the field values
//print_r($fields);
//validate if specific form
if ($form_data['id']==1695)
{
$user = get_current_user_id();
$user_post_count = count_user_posts( $user , 'review' );
$user_data = get_userdata($user);
$user_role = $user_data->roles;
if ( $user_role[0] == 'author' && $user_post_count > 0)
{
//set error message for my_field
$errors['wpcf-user-validation']='Only 1 review per shop is allowed';
}
}
//return result
return array($fields,$errors);
}
Dear Tino,
You can try to modify the codes from:
if ( $user_role[0] == 'author' && $user_post_count > 0)
To:
if ( in_array($user_role[0], array('author', 'contributor', 'editor')) && $user_post_count > 0)

Hi Luo,
Thanks, your suggestion worked, but I still require further help. The following is my latest code:
//Limit the number of reviews for a user
add_filter('cred_form_validate','my_validation',10,2);
function my_validation($field_data, $form_data)
{
//field data are field values and errors
list($fields,$errors)=$field_data;
//uncomment this if you want to print the field values
//print_r($fields);
//validate if specific form
if ($form_data['id']==1695)
{
$user = get_current_user_id();
$user_post_count = count_user_posts( $user , 'review' );
$user_data = get_userdata($user);
$user_role = $user_data->roles;
if ( in_array($user_role[0], array('author', 'contributor', 'editor')) && $user_post_count > 0)
{
//set error message for my_field
$errors['wpcf-user-validation']='Only 1 review per product is allowed';
}
}
//return result
return array($fields,$errors);
}
The above code limits the user to one review on the entire site. What is happening now is, when a user goes to another product (Parent CPT = shop) and wants to leave a review the error message is displayed.
How can we adjust this code to limit and allow one Review (Child CPT) per Shop (Parent CPT) ?
Thanks
I assume the parent post type "Shop" is using slug "shop", for example, you can modify your codes from:
$user_post_count = count_user_posts( $user , 'review' );
To:
$shop_id = $_POST['_wpcf_belongs_shop_id'];
$args = array(
'meta_key' => '_wpcf_belongs_shop_id',
'meta_value' => $shop_id,
'post_type' => 'review'
);
$query = new WP_Query( $args );
$user_post_count = 0;
if(isset($query->found_posts)){
$user_post_count = $query->found_posts;
}
Thank you for your superb help Luo, it worked perfectly. Here is my final code for any body else wanting the solution.
//Limit the number of reviews for a user on a parent CPT
add_filter('cred_form_validate','my_validation',10,2);
function my_validation($field_data, $form_data)
{
//field data are field values and errors
list($fields,$errors)=$field_data;
//uncomment this if you want to print the field values
//print_r($fields);
//validate if specific form
if ($form_data['id']==1695)
{
$user = get_current_user_id();
$shop_id = $_POST['_wpcf_belongs_shop_id'];
$args = array(
'meta_key' => '_wpcf_belongs_shop_id',
'meta_value' => $shop_id,
'post_type' => 'review'
);
$query = new WP_Query( $args );
$user_post_count = 0;
if(isset($query->found_posts)){
$user_post_count = $query->found_posts;
}
$user_data = get_userdata($user);
$user_role = $user_data->roles;
if ( in_array($user_role[0], array('subscriber', 'author', 'contributor', 'editor')) && $user_post_count > 0)
{
//set error message for my_field
$errors['wpcf-user-validation']='<span><i class="fa fa-star" aria-hidden="true"></i> You have already left a Review!</span>';
}
}
//return result
return array($fields,$errors);
}
Hi Luo,
After further testing I still require assistance.
The code above allows only one review in one shop to be reviewed by only one user.
Ex: When I try to submit another review to the same shop using another user, then the error message appears restricting submission of their first review.
We need to enable multiple users to review one shop, and if they try to submit another review for that same shop, then the error message appears.
You can add an author filter into the query, for example, replace this from:
$args = array(
'meta_key' => '_wpcf_belongs_shop_id',
'meta_value' => $shop_id,
'post_type' => 'review'
);
To:
$args = array(
'meta_key' => '_wpcf_belongs_shop_id',
'meta_value' => $shop_id,
'post_type' => 'review',
'author' => get_current_user_id()
);
And test again.

Thank you so much Luo. It works perfectly.
My final code:
//Limit the number of reviews for a user on a parent CPT
add_filter('cred_form_validate','my_validation',10,2);
function my_validation($field_data, $form_data)
{
//field data are field values and errors
list($fields,$errors)=$field_data;
//uncomment this if you want to print the field values
//print_r($fields);
//validate if specific form
if ($form_data['id']==1695)
{
$user = get_current_user_id();
$shop_id = $_POST['_wpcf_belongs_shop_id'];
$args = array(
'meta_key' => '_wpcf_belongs_shop_id',
'meta_value' => $shop_id,
'post_type' => 'review',
'author' => get_current_user_id()
);
$query = new WP_Query( $args );
$user_post_count = 0;
if(isset($query->found_posts)){
$user_post_count = $query->found_posts;
}
$user_data = get_userdata($user);
$user_role = $user_data->roles;
if ( in_array($user_role[0], array('subscriber', 'author', 'contributor', 'editor')) && $user_post_count > 0)
{
//set error message for my_field
$errors['wpcf-user-validation']='<span><i class="fa fa-star" aria-hidden="true"></i> You have already left a Review!</span>';
}
}
//return result
return array($fields,$errors);
}
