图片显示在 wordpress 本地主机上传文件夹中，但未在 wordpress 媒体库（wp 仪表板）中更新）

Question

我正在尝试在子主题中使用 wp 自定义模板上传图片，但是当我上传任何图片时。它出现在 "E:\Xamp\htdocs\website\wp-content\uploads19" 但没有上传到 wp 仪表板媒体库。

不允许我为此任务使用任何插件。

$post_id = wp_insert_post($my_post);

if(isset($_FILES['file']['name'])){
    if(! function_exists('wp_handle_upload')){
        require_once(ABSPATH.'wp-admin/includes/file.php');
    }
    $uploadfile = $_FILES['file'];
    print_r($uploadfile);
    $upload_overrides = array('test_form' => false );

    $moveupload = wp_handle_upload($uploadfile,$upload_overrides);
    if($moveupload && ! isset($moveupload['error'])){
        echo "</Pre";
        wp_update_attachment_metadata( $post_id, $moveupload);
        print_r($moveupload);
        echo "Post/>";
    }else{
        echo $moveupload['error'];
    }
}

Answer 1

将文件上传到 wp-content/uploads 不会显示在媒体库中，这些媒体 ID 需要存在于数据库中才能显示在媒体库中。

如果上传文件夹中已有文件并想将它们添加到数据库中

但这不是正确的解决方案，而是解决上传文件夹的权限问题。

谢谢

我使用自定义 php 代码解决了这个问题。

$upload = wp_upload_bits($_FILES["file"]["name"], null, file_get_contents($_FILES["file"]["tmp_name"]));
$filename = $upload['file'];
$wp_filetype = wp_check_filetype($filename, null );
// print_r($filename);
$attachment = array(
    'post_mime_type' => $wp_filetype['type'],
    'post_title' => sanitize_file_name($filename),
    'post_content' => '',
    'post_status' => 'inherit'
);
$attach_id = wp_insert_attachment( $attachment, $filename, $post_id );
require_once(ABSPATH . 'wp-admin/includes/image.php');
$attach_data = wp_generate_attachment_metadata( $attach_id, $filename );
wp_update_attachment_metadata( $attach_id, $attach_data );
    set_post_thumbnail( $post_id, $attach_id );

Can try out another piece of code here:
--------------------------
$upload_overrides = array( "test_form" => false );

$uploaded_file = wp_handle_upload ($file, $upload_overrides);

if( isset( $uploaded_file ["file"] )) {
    $file_name_and_location = $uploaded_file ["file"];
    $file_title_for_media_library = $title;

    $attachment = array(
        "post_mime_type" => $uploaded_file_type,
        "post_title" => addslashes( $file_title_for_media_library ),
        "post_content" => "",
        "post_status" => "inherit"
    );

    if( ! is_null( $post )) {
        if ( ! is_numeric( $post )) {
            $post = $post->ID;
        } // if ()

        $attachment ['post_parent'] = $post;
    } // if ()

    $id = wp_insert_attachment( $attachment, $file_name_and_location );

    require_once( ABSPATH."wp-admin/includes/image.php" );

    $attach_data = wp_generate_attachment_metadata( $id, $file_name_and_location );
    wp_update_attachment_metadata( $id, $attach_data );
} // if ()
