Wordpress - 过滤视频嵌入代码

Question

In Wordpress, how do you filter a textarea that saves a vimeo embed code in theme admin? Using sanitize_text_field will make the code unusable when saving into db via update_post_meta.

    $postmeta = sanitize_text_field( $_POST['embed_video']);
    update_post_meta($post_id, 'embed_video',$postmeta );

Answer 1

I often approach wordpress video embeds from the other angle, creating the embed code in the template, for example rather than have someone embed a video like this:

<iframe src="http://player.vimeo.com/video/69277800?title=0&amp;byline=0&amp;portrait=0&amp;badge=0" width="577" height="325" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe>

I'd have them just insert the id, in this case 69277800. Then I'd put in my template

<?php if(!empty($video_id)):?>
<iframe src="http://player.vimeo.com/video/<?php echo $video_id;?>?title=0&amp;byline=0&amp;portrait=0&amp;badge=0" width="577" height="325" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe>
<?php endif;?>
