Question

我有自定义页面模板。此模板具有用户可以上载文件的自定义表单。现在，上传的文件不会在MySQL中上传，而是在文件系统/本地文件夹（本地计算机）中上传。

我已经有了一个PHP代码段，但代码无效，我收到了错误。

如何解决这个问题？

段：

if(isset($_POST['submit'])){
    $lastName = isset($_POST['lastName']) ? $_POST['lastName'] : '';
    $resumeFile = isset($_FILE['resumeFile']['name']) ? $_FILE['resumeFile']['name']: '';

$info = pathinfo($_FILES['resumeFile']['name']);
$ext = $info['extension'];
$file_rename= $lastName.$ext; 

$target = 'C://xampp/htdocs/files/'.$file_rename;
move_uploaded_file($_FILES['resumeFile']['tmp_name'], $target);
}

错误：

Notice: Undefined index: resumeFile .... on line 130
Notice: Undefined index: extension .... on line 131
Notice: Undefined index: resumeFile .... on line 135

请尝试使用以下代码段，将文件上传到默认uploads目录以外的其他目录。

function change_my_upload_directory( $dir ) {
    return array (
        'path'   => WP_CONTENT_DIR . '/your-custom-dir',
        'url'    => $dir['baseurl'] . '/wp-content/your-custom-dir',
        'subdir' => '/your-custom-dir',
    ) + $dir;   
}

if( isset( $_FILES[ "resumeFile" ] ) ) {

    if ( !function_exists( 'wp_handle_upload' ) ) {
        require_once( ABSPATH . 'wp-admin/includes/file.php' );
    }
    // Overrides the uploads directory location
    add_filter( 'upload_dir', 'change_my_upload_directory' );       

    $movefile = wp_handle_upload( $_FILES[ "resumeFile" ], array( 'test_form' => false ) ); 

    // Remove the filter, so that subsequant uploads will be dsent to default uploads directory
    remove_filter( 'upload_dir', 'change_my_upload_directory' );

    return $movefile;

}    
return false;

wp_handle_upload将返回包含以下属性的对象

$movefile[ 'file' ] // uploaded file object
$movefile[ 'url' ] // current url ( file location ) of the file
$movefile[ 'type' ] // uploaded file type

如果wp_handle_upload失败，它将返回错误对象，您可以像这样检查上传失败

if( isset( $movefile[ 'error' ] ) ) {
    // handle the error
}
