Access to Uploaded Attachments, as of Version 5.4

Hi,

I’m starting to gain back progrematic access to uploaded attachments, with version 5.4.

The key here is that now an uploaded attachment file is in an array. This requires “[0]” suffix retrieving data.

Sadly, the above did not fully serve as a solution.

I am starting to see a possible solution, reading the code of the Contact Form 7 Database Addon – CFDB7 plugin. This plugin is already adjusted to fetching files, and is competable with CF7 new data structure.

It’s contact-form-cfdb-7.php code contains the following code:

function cfdb7_before_send_mail( $form_tag ) {

    global $wpdb;
    $cfdb          = apply_filters( 'cfdb7_database', $wpdb );
    $table_name    = $cfdb->prefix.'db7_forms';
    $upload_dir    = wp_upload_dir();
    $cfdb7_dirname = $upload_dir['basedir'].'/cfdb7_uploads';
    $time_now      = time();

    $submission   = WPCF7_Submission::get_instance();
    $contact_form = $submission->get_contact_form();
    $tags_names   = array();
    $strict_keys  = apply_filters('cfdb7_strict_keys', false);  

    if ( $submission ) {

        $allowed_tags = array();

        if( $strict_keys ){
            $tags  = $contact_form->scan_form_tags();
            foreach( $tags as $tag ){
                if( ! empty($tag->name) ) $tags_names[] = $tag->name;
            }
            $allowed_tags = $tags_names;
        }

        $not_allowed_tags = apply_filters( 'cfdb7_not_allowed_tags', array( 'g-recaptcha-response' ) );
        $allowed_tags     = apply_filters( 'cfdb7_allowed_tags', $allowed_tags );
        $data             = $submission->get_posted_data();
        $files            = $submission->uploaded_files();
        $uploaded_files   = array();

        foreach ($_FILES as $file_key => $file) {
            array_push($uploaded_files, $file_key);
        }
        foreach ($files as $file_key => $file) {
            $file = is_array( $file ) ? reset( $file ) : $file;
            if( empty($file) ) continue;
            copy($file, $cfdb7_dirname.'/'.$time_now.'-'.$file_key.'-'.basename($file));
        }

        $form_data   = array();

        $form_data['cfdb7_status'] = 'unread';
        foreach ($data as $key => $d) {
            
            if( $strict_keys && !in_array($key, $allowed_tags) ) continue;

            if ( !in_array($key, $not_allowed_tags ) && !in_array($key, $uploaded_files )  ) {

                $tmpD = $d;

                if ( ! is_array($d) ){
                    $bl   = array('\"',"\'",'/','\\','"',"'");
                    $wl   = array('"',''','/', '\','"',''');
                    $tmpD = str_replace($bl, $wl, $tmpD );
                }

                $form_data[$key] = $tmpD;
            }
            if ( in_array($key, $uploaded_files ) ) {
                $file = is_array( $files[ $key ] ) ? reset( $files[ $key ] ) : $files[ $key ];
                $file_name = empty( $file ) ? '' : $time_now.'-'.$key.'-'.basename( $file ); 
                $form_data[$key.'cfdb7_file'] = $file_name;
            }
        }

        /* cfdb7 before save data. */
        $form_data = apply_filters('cfdb7_before_save_data', $form_data);

        do_action( 'cfdb7_before_save', $form_data );

        $form_post_id = $form_tag->id();
        $form_value   = serialize( $form_data );
        $form_date    = current_time('Y-m-d H:i:s');

        $cfdb->insert( $table_name, array(
            'form_post_id' => $form_post_id,
            'form_value'   => $form_value,
            'form_date'    => $form_date
        ) );

        /* cfdb7 after save data */
        $insert_id = $cfdb->insert_id;
        do_action( 'cfdb7_after_save_data', $insert_id );
    }

}

add_action( 'wpcf7_before_send_mail', 'cfdb7_before_send_mail' );

I recommend focusing at this part of the code:

$data             = $submission->get_posted_data();
        $files            = $submission->uploaded_files();
        $uploaded_files   = array();

        foreach ($_FILES as $file_key => $file) {
            array_push($uploaded_files, $file_key);
        }
        foreach ($files as $file_key => $file) {
            $file = is_array( $file ) ? reset( $file ) : $file;
            if( empty($file) ) continue;
            copy($file, $cfdb7_dirname.'/'.$time_now.'-'.$file_key.'-'.basename($file));
        }
