Golden Apples Design 创建了（据我所知）媒体上传功能，许多人在WP上。A和其他地方似乎建议。但所有的问答；正如我在StackExchange上看到的那样，我同意创建一个全新的帖子。
从前端上传媒体、将其附加到当前帖子、生成适当的缩略图，然后刷新[库]中显示新图像的页面的最佳方式是什么？
下面是Than的代码：在函数文件中。。。
function insert_attachment($file_handler,$post_id,$setthumb=\'false\') {
// check to make sure its a successful upload
if ($_FILES[$file_handler][\'error\'] !== UPLOAD_ERR_OK) __return_false();
require_once(ABSPATH . "wp-admin" . \'/includes/image.php\');
require_once(ABSPATH . "wp-admin" . \'/includes/file.php\');
require_once(ABSPATH . "wp-admin" . \'/includes/media.php\');
$attach_id = media_handle_upload( $file_handler, $post_id );
if ($setthumb) update_post_meta($post_id,\'_thumbnail_id\',$attach_id);
return $attach_id;
在页面模板标题中。。。
// set $post_id to the id of the post you want to attach
// these uploads to (or \'null\' to just handle the uploads
// without attaching to a post)
if ($_FILES) {
foreach ($_FILES as $file => $array) {
$newupload = insert_attachment($file,$post_id);
// $newupload returns the attachment id of the file that
// was just uploaded. Do whatever you want with that now.
}
}
上载使用的表单。。。
<form method="post" action="#" enctype="multipart/form-data" >
<input type="file" name="an_uploaded_attachment">
<input type="file" name="another_uploaded_attachment">
<input type="file" name="yet_another_uploaded_attachment">
<input type="submit">
<form>

@实际上是AboSamianswered this question 在我的搜索调查中没有出现的一个旧帖子中。虽然他实际上在寻找其他东西，但他的示例代码工作得很好。
下面是脚本：
<?php $post_id = $post->ID;
if ( isset( $_POST[\'html-upload\'] ) && !empty( $_FILES ) ) {
require_once(ABSPATH . \'wp-admin/includes/admin.php\');
$id = media_handle_upload(\'async-upload\', $post_id); //post id of Client Files page
unset($_FILES);
if ( is_wp_error($id) ) {
$errors[\'upload_error\'] = $id;
$id = false;
}
if ($errors) {
echo "<p>There was an error uploading your file.</p>";
} else {
echo "<p>Your file has been uploaded.</p>";
}
}
?>
<form id="file-form" enctype="multipart/form-data" action="<?php echo $_SERVER[\'REQUEST_URI\']; ?>" method="POST">
<p id="async-upload-wrap"><label for="async-upload">upload</label>
<input type="file" id="async-upload" name="async-upload"> <input type="submit" value="Upload" name="html-upload"></p>
<p><input type="hidden" name="post_id" id="post_id" value="<?php echo $post_id ?>" />
<?php wp_nonce_field(\'client-file-upload\'); ?>
<input type="hidden" name="redirect_to" value="<?php echo $_SERVER[\'REQUEST_URI\']; ?>" /></p>
<p><input type="submit" value="Save all changes" name="save" style="display: none;"></p>
</form>
