// Check that the nonce is valid, and the user can edit this post.
if (
isset($_POST['my_image_upload_nonce'], $_POST['post_id'])
&& wp_verify_nonce($_POST['my_image_upload_nonce'], 'my_image_upload')
&& current_user_can('edit_post', $_POST['post_id'])
) {
// The nonce was valid and the user has the capabilities, it is safe to continue.
// These files need to be included as dependencies when on the front end.
require_once(ABSPATH . 'wp-admin/includes/image.php');
require_once(ABSPATH . 'wp-admin/includes/file.php');
require_once(ABSPATH . 'wp-admin/includes/media.php');
// Let WordPress handle the upload.
// Remember, 'my_image_upload' is the name of our file input in our form above.
$url=WPWSL_PLUGIN_URL . '/img/' . $imageSize . '.png';
// update_option('upload_path',WP_CONTENT_DIR.'/uploads');
update_option('upload_path',WPWSL_PLUGIN_URL.'/img/');
$attachment_id = media_handle_upload('my_image_upload', $_POST['post_id']);
if (is_wp_error($attachment_id)) {
// There was an error uploading the image.
echo "<p>There was an error uploading your file.</p>";
} else {
// The image was uploaded successfully!
echo "<p>The image was uploaded successfully!</p>";
add_filter('img', $attachment_id);
// add_filter('img', 'custom_upload_directory');
}
} else {
echo "<p>The security check failed, maybe show the user an error</p>";
// The security check failed, maybe show the user an error.

<input id="submit_my_image_upload" name="submit_my_image_upload" type="submit" value="Upload"/>你看下这两个方案，药到病除
