我有一个表单，它使用 public.php 中的这个函数保存来自各个字段的数据：
public function save_ad_content() {
// If $_POST['aas_upload_ad'] is set
if ( ! empty( $_POST['advanced-ads-selling-upload-ad'] ) && $_POST['advanced-ads-selling-upload-ad'] == 'advanced-ads-selling-upload-ad' ) {
$data = array(); // Declare variables
switch ( $_POST['advads_selling_ad_type'] ) { // Switch case on ad_type selected
case 'image':
$errors = ''; // Declare variables
$file_name = $_FILES['advads_selling_ad_image']['name']; // Get file name
$file_size = $_FILES['advads_selling_ad_image']['size']; // Get file size
$file_tmp = $_FILES['advads_selling_ad_image']['tmp_name']; // Get file's temporary name
$file_type = $_FILES['advads_selling_ad_image']['type']; // Get file type
$target_url = ! empty( $_POST['advads_selling_ad_url'] ) ? $_POST['advads_selling_ad_url'] : '';
$file_datas = explode( '.', $file_name ); // Explode file name to retrieve extension
foreach ( $file_datas as $file_data ) {
$file_data_arr[] = $file_data; // Convert associative array to normal array
}
$file_ext = strtolower( end( $file_data_arr ) ); // Get file extension
$expensions = array( 'jpeg', 'jpg', 'png', 'gif' ); // Declare variables for allowed extension types
if ( in_array( $file_ext, $expensions ) === false ) { // if file extensions is within allowed extensions
$errors = esc_html__( 'Extension not allowed, please choose a JPEG, PNG or GIF file.', 'advanced-ads-selling' );
}
$max_file_size = apply_filters( 'advanced-ads-selling-upload-file-size', 1048576 );
if ( $file_size > $max_file_size ) {
$errors = sprintf(
// translators: %s is a file size with one decimal
__( 'The allowed file size is %s MB', 'advanced-ads-selling' ),
number_format_i18n( $max_file_size / 1000000, 1 )
);
}
if ( empty( $errors ) ) {
// Get the path to the upload directory.
$wp_upload_dir = wp_upload_dir();
// These files need to be included as dependencies when on the front end.

/*

// get ad object
$ad = new Advanced_Ads_Ad( $ad_id );
$ad->type = 'image';
$output['image_id'] = $attach_id;
$ad->set_option( 'output', $output );
$ad->url = esc_url( $_POST['advads_selling_ad_url'] );

$ad->content = $ad_post_content;
$ad->status = 'pending';
if ( $attach_id ) {
$attachment_meta = wp_get_attachment_metadata( $attach_id );

}
}
/**
* Allow add-ons to add their own logic for another custom ad type
*/
do_action( 'advanced-ads-selling-save-ad-content-after', $_POST );
}
}
我有 2 个可用的钩子：
do_action( 'advanced-ads-selling-ad-setup-form-types-after', $ad_types, $_item );
用于显示自定义字段
和
add_action('advanced-ads-selling-save-ad-content-after');
用于保存自定义字段。
所以我写了我的第一个回调来显示我自己的字段：
add_action('advanced-ads-selling-ad-setup-form-types-after', 'display_ads_custom_field');
function display_ads_custom_field () {
?>
<div class="myfield">
<p><?php esc_html_e( 'My Field Title' ); ?></p>
<textarea class="myfield"></textarea>
</div>
<?php
}
然后我将保存钩子与保存功能一起使用：
add_action('advanced-ads-selling-save-ad-content-after', 'save_ad_content');
但是没有显示任何字段，也没有保存任何内容。
最初，我能够使用我的 advanced-ads-sales-ad-setup-form-types-after 钩子显示该字段，但它没有被保存。现在它甚至没有显示。
我究竟做错了什么？在表单标签之间定义优先级是否必要？表单保存功能和我的字段之间还没有联系，那么它应该如何保存它的值呢？
提前致谢！
最后这是我的代码，没有错误并提交，但不会保存：
add_action('advanced-ads-selling-ad-setup-form-types-after', 'display_ad_headline_field');
function display_ad_headline_field () {
?>
<div class="my_adfield">
<p><?php esc_html_e( 'My ad field name', 'advanced-ads-selling' ); ?></p>
<textarea name="my_adfield_name"></textarea>
</div>
<?php
}
add_action( 'advanced-ads-selling-save-ad-content-after', 'save_my_field' );
function save_my_field($ad_id) {
if ( ! isset( $_POST['my_adfield_name'] ) || ! trim( $_POST['my_adfield_name'] ) ) {
$errors = esc_html__( 'Ad content missing.', 'advanced-ads-selling' );
}
if ( empty( $errors ) ) {
$ad_id = Advanced_Ads_Selling_Order::order_item_id_to_ad_id( $_POST['advads_selling_order_item'] );
// update the ad post
$new_ad_content = array(
'ID' => $ad_id,
'post_content' => trim( $_POST['my_adfield_name'] ),
'post_status' => 'pending',
);
$return = wp_update_post( $new_ad_content );
if ( is_wp_error( $return ) ) {
die( esc_html__( 'Error when submitting the ad. Please contact the site admin.', 'advanced-ads-selling' ) );
}
$_POST['success'] = 'success';
} else {
$_POST['errors'] = $errors;
}
}
