Hi @thankssforhelp
Thank you for response and additional information!
You will need a bit of additional custom code for this:
<?php
if ( ! defined( 'ABSPATH' ) ) {
exit;
}
if ( ! class_exists( 'WPMUDEV_Frominator_Upload_Email_Attachment' ) ) {
class WPMUDEV_Frominator_Upload_Email_Attachment {
public $attachments = array();
private static $_instance = null;
public static function get_instance() {
if( is_null( self::$_instance ) ){
self::$_instance = new WPMUDEV_Frominator_Upload_Email_Attachment();
}
return self::$_instance;
}
private function __construct() {
add_filter( 'wp_mail', array( $this, 'filter_email_args' ) );
add_filter( 'forminator_custom_form_submit_errors', array( $this, 'manage_field_data' ), 20, 3 );
}
public function manage_field_data( $submit_errors, $form_id, $data ) {
$field_ids = array( 'hidden-1', 'hidden-2' ); // fields that should be used for attachments
if ( empty( $submit_errors ) ) {
foreach ( $data as $key => $field_data ) {
if ( ! in_array( $field_data['name'], $field_ids ) ) {
continue;
}
$this->attachments[] = ABSPATH . $field_data['value'];
}
}
return $submit_errors;
}
public function filter_email_args( $mail_args ) {
if ( ! empty( $this->attachments ) ) {
$mail_args[ 'attachments' ] = $this->attachments;
}
return $mail_args;
}
}
if ( ! function_exists( 'wpmudev_forminator_upload_email_attachment' ) ) {
function wpmudev_forminator_upload_email_attachment() {
return WPMUDEV_Frominator_Upload_Email_Attachment::get_instance();
};
add_action( 'plugins_loaded', 'wpmudev_forminator_upload_email_attachment', 10 );
}
}
To add it to the site:
1. create an empty file with a .php extension (e.g. “forminator-hidden-field-mail-attachment.php”)
2. copy and paste code into it
3. in this line of the code
$field_ids = array( 'hidden-1', 'hidden-2' ); // fields that should be used for attachments
replace hidden-1 and hidden-2 with (one or more; if more – comma separated) IDs of your hidden fields that contain the file to attach
4. save the file and upload it to the “/wp-content/mu-plugins” folder of your site’s WordPress installation.
If there is no “mu-plugins” folder directly in “wp-content”, just create an empty one first.
This should work out of the box but note also that in your hidden field(s) you need to use specific path format. For example, if you want to attach the image located at
https://yoursite.com/wp-content/uploads/something/myimage.jpg
you would set the hidden field to “Custom value” option and in value put exactly this
wp-content/uploads/something/myimage.jpg
If this path is added automatically to hidden field and it is a bit different, then let us know exactly what the path is (you can just share example one) and we should be able to modify the code accordingly.
Best regards,
Adam
