Fetch First Video Tag
User

Assistant
You can fetch the first “ tag from a WordPress post's content programmatically using PHP. Here's how you can do it:
### Method 1: Using `get_the_content()` and `DOMDocument`
function get_first_video_from_post($post_id) {
$post = get_post($post_id);
if (!$post) {
return '';
}
$content = $post->post_content;
// Load content into DOMDocument
$dom = new DOMDocument();
libxml_use_internal_errors(true);
$dom->loadHTML('<?xml encoding="utf-8" ?>' . $content);
libxml_clear_errors();
$videos = $dom->getElementsByTagName('video');
// Return first video tag if found
if ($videos->length > 0) {
return $dom->saveHTML($videos->item(0));
}
return '';
}
// Usage
$post_id = get_the_ID(); // Get current post ID
echo get_first_video_from_post($post_id);### Method 2: Using `preg_match`
If you prefer regex, you can extract the first “ tag using `preg_match`:
function get_first_video_from_content($post_id) {
$post = get_post($post_id);
if (!$post) {
return '';
}
$content = $post->post_content;
// Match the first <video> tag
preg_match('/<video.*?>.*?</video>/is', $content, $matches);
return !empty($matches) ? $matches[0] : '';
}
// Usage
$post_id = get_the_ID(); // Get current post ID
echo get_first_video_from_content($post_id);### Explanation:
– **Method 1**: Uses `DOMDocument` to parse the content and extract the first “ tag.
– **Method 2**: Uses `preg_match` to find the first “ tag.
