Insert posting automatically based in acf field

Question

good day

I found a code that works, but it creates several posts of the same name, do not want that, he wanted to create only once post_type if the value is 'x', but he is creating a 'x' every time updates , how do I create it only once this post_type?

My Code:

<?php 
    wp_insert_post( array(
        'post_status' => 'publish',
        'post_type' => 'fornecedores', // post_type which is created posting
        'post_title' => get_field('fornecedor'), // Custom field to generate the post type
        'post_content' => ''
    )
)
?>

Code is in a loop of the post type products.
Understand me?

Answer 1

Before inserting check if post exists:

$exists = get_page_by_title( get_field('fornecedor'), OBJECT, 'fornecedores');

if ( empty( $exists ) ) {
  wp_insert_post( array(
    'post_status' => 'publish',
    'post_type' => 'fornecedores', // post_type which is created posting
    'post_title' => get_field('fornecedor'), // Custom field to generate the post type
    'post_content' => ''
  )
}

Answer 2

1. Create a post_type named "Products"
2. Create a post_type named "Suppliers"
3. In "Custom Fields", create a new field group and add a "rule" so that it shows up on "Products"
4. Then add a new field and select the "Relationship" field type
5. Under "Post Type" for that field, choose "Suppliers"

Now on your Products posts, you can choose Suppliers.

Is... that what you are asking?
