将图片优化上传CF7图片数据保存到CPT的CF7图片字段中

Question

我们已经用cf7创建了一个表单，并用“图像优化和上传CF7”插件创建了图像字段，现在我们想要将每个字段的数据保存到cpt，但无法将cf7图像保存到该特定cpt的acf图像字段中。以下是我的代码：

function save_posted_data( $posted_data ) {


       $args = array(
         'post_type' => 'prescriptions',
         'post_status'=>'draft',
         'post_title'=>$posted_data['phonenumber'],
       );
       $post_id = wp_insert_post($args);

       if(!is_wp_error($post_id)){
         if( isset($posted_data['location']) ){
           update_post_meta($post_id, 'location', $posted_data['location']);
         }
         if( isset($posted_data['phonenumber']) ){
           update_post_meta($post_id, 'contact_number', $posted_data['phonenumber']);
         }

         if( isset($posted_data['prescriptiontext']) ){
           update_post_meta($post_id, 'prescription_description', $posted_data['prescriptiontext']);
         }

         if ( !function_exists('wp_handle_upload') ) {
require_once(ABSPATH . 'wp-admin/includes/file.php');
}

// Move file to media library
$movefile = wp_handle_upload( $_FILES[$posted_data['prescriptionimage']], array('test_form' => false) );

// If move was successful, insert WordPress attachment
if ( $movefile && !isset($movefile['error']) ) {
$wp_upload_dir = wp_upload_dir();
$attachment = array(
'guid' => $wp_upload_dir['url'] . '/' . basename($movefile['file']),
'post_mime_type' => $movefile['type'],
'post_title' => preg_replace( '/\.[^.]+$/', "", basename($movefile['file']) ),
'post_content' => "",
'post_status' => 'inherit'
);
$attach_id = wp_insert_attachment($attachment, $movefile['file']);
update_field('prescription_image', $attach_id, $post_id);

}
      //and so on ...
      return $posted_data;
     }
 }

add_filter( 'wpcf7_posted_data', 'save_posted_data' );

这是我的代码，$posted_data‘规定图像’是cf7中的图像字段名称，图像另存为1191566397/ID_file_download.png，就像this.We一样不知道代码出了什么问题有人能帮我吗

我有一段代码可能会对你有所帮助。虽然我没有具体回答您的问题，但我相信这将为您指明正确的方向。你不应该挂接wpcf7_posted_data，而应该挂接wpcf7_before_send_mail，在那里你可以接收发布的数据。在我的例子中，我添加了一个附件，并包含了作者元数据。但我相信，有了这个，你可以弄清楚如何附加到你的ACF字段？我让$posted_data返回您上面所拥有的内容。

<?php

add_action( 'wpcf7_before_send_mail', 'he_cf7_process_form', 10, 1);
/**
 * @param object $contact_form The UserID of the Poster
 */
function he_cf7_process_form($contact_form) {
    // check to make sure it only fires on your contact form
    if ( $contact_form->id() == integer_of_your_contact_form ) return;

    // Get the contact form submitted data
    $submission = WPCF7_Submission::get_instance();
    if ($submission) {
        $posted_data = $submission->get_posted_data();
        $uploaded_files = $submission->uploaded_files();
    } else {
        return;
    }
    // Your field name of the file goes here
    $files = $_FILES['field-name'];

    if (empty($uploaded_files)) {
        return 0;
    } else {
        $image_name = basename($uploaded_files['field-name']);
        $image_location = $uploaded_files['field-name'];
        $image_content = file_get_contents($image_location);

        $wp_upload_dir = wp_upload_dir();

        $upload = wp_upload_bits($image_name, null, $image_content);

        $filename = $upload['file'];

        $attachment = array(
            'guid' => $wp_upload_dir['url'] . '/' . basename($filename),
            'post_mime_type' => $files['type'],
            'post_title' => preg_replace('/\.[^.]+$/', '', basename($filename)),
            'post_content' => '',
            'post_status' => 'inherit'
        );

        $attach_id = wp_insert_attachment($attachment, $filename);

        // Make sure that this file is included, as wp_generate_attachment_metadata() depends on it.
        require_once(ABSPATH . 'wp-admin/includes/image.php');

        // Generate the metadata for the attachment, and update the database record.
        $attach_data = wp_generate_attachment_metadata($attach_id, $filename);
        wp_update_attachment_metadata($attach_id, $attach_data);

        $arg = array(
            'ID' => $attach_id,
            'post_author' => $userid,
        );

        wp_update_post($arg);
        
    }
}
