I have a front-end Edit form and I want to have a number field automatically incremented by 1, from whatever it currently is, when the form is submitted. And this would be on a page with multiple Post Edit forms so I need it to avoid updating all forms, just the one being submitted.
To achieve this functionality in Toolset Forms, you can use custom PHP code to automatically increment a number field on the specific post being edited. Toolset provides hooks that allow you to add custom logic to form submissions. Here's how you can do it:
Add the code below to the custom PHP feature of Toolset:
add_action('cred_save_data', 'increment_number_field', 10, 2);
function increment_number_field($post_id, $form_data) {
// Specify the ID(s) of your Edit forms where this should apply
$target_form_ids = array(123, 456); // Replace with your actual form IDs
// Check if the submitted form is one of the target forms
if (in_array($form_data['id'], $target_form_ids)) {
// Get the current value of the custom field
$current_value = get_post_meta($post_id, 'wpcf-your-number-field', true); // Replace 'your-number-field' with your actual field slug
// Ensure it's a number and increment it
$new_value = (int)$current_value + 1;
// Update the custom field with the incremented value
update_post_meta($post_id, 'wpcf-your-number-field', $new_value);
}
}
Replace 123, 456 in $target_form_ids with the ID(s) of your Edit forms.
Replace your-number-field with the slug of your number field in the post meta.
Ensure the field is a single-line number field in Toolset so that the data is properly validated as an integer.
The prefix wpcf- is automatically added to Toolset custom fields when stored in the database. This is why it is included in the get_post_meta and update_post_meta functions.
Please Note: This is considered a custom development and it is outside of our support scope. We provided the starting point for the customization but fine tuning and additional development can not be done by us.
