Question

我创建了动态添加/删除字段，其中一个是文件上载字段。一切正常。但是有一个问题。当我在文件字段中添加图像并在其他字段中填充其他详细信息时，数据不会插入数据库中。

当我添加3个字段时，意味着当我添加最多3个图像时，它可以正常工作，数据被插入。但是当我添加第四个图像时，什么也不会插入。

我不明白为什么脚本奇怪地起作用。

以下是代码：

<?php

if ( isset( $_POST['project_draft0'] ) ) {

$user_id = get_current_user_id();

$member_details->member_image = array_map( 'sanitize_file_name', $_FILES['member_image']['name'] );
$member_details->member_name = array_map( 'sanitize_text_field', $_POST['member_name'] );
$member_details->member_email = array_map( 'sanitize_text_field', $_POST['member_email'] );
$member_details->member_role = array_map( 'sanitize_text_field', $_POST['member_role'] );
$member_details->member_fb = array_map( 'sanitize_text_field', $_POST['member_fb'] );

$member_details_encode = wp_json_encode( $member_details );

  global $wpdb;

  $member_result = $wpdb->insert( 'oc_project_members',

         array( 

              'author_id'      => $user_id,
              'member_details' => $member_details_encode

              ),

         array( 

              '%d',
              '%s'

      )

    );

}

?>
