Gravity Forms: automatically populating fields by getting the data of a YouTube

  • I am using Gravity Forms on my WordPress website where people can share videos, and I want the title, description, etc. to be populated automatically by getting the data from the YouTube video. After browsing Google for a couple of hours, I can’t seem to get it to work. (I have 0 experience in php)

    All I was able to do is get the video ID from the URL by using this code:

    add_filter("gform_save_field_value", "save_field_value", 10, 4);
function save_field_value($value, $lead, $field, $form){
        //if not the form with fields to encode, just return the unaltered value without checking the fields
        if(absint($form["id"]) <> 1) /* If the form is not ID 1 */
                return $value;

        //array of field ids to encode
        $encode_fields = array(2); /* Field 2 is the video URL from which we need the video ID */

    parse_str( parse_url( $value, PHP_URL_QUERY ), $my_array_of_vars );

        //see if the current field id is in the array of fields to encode; encode if so, otherwise return unaltered value
        if(in_array($field["id"],$encode_fields))
                return $my_array_of_vars['v']; /* Return the video ID i.e. the value after '&v=' */
        else
                return $value;
}

    I also found this to get the data from the video: https://stackoverflow.com/questions/10896233/how-can-i-retrieve-youtube-video-details-from-video-url-using-php

    Hope someone can help me, thanks!

    I’ve been searching Google for how to get the title from a video using PHP and I found this:

    <?php
$video_id = 'y8Kyi0WNg40';
$content = file_get_contents("https://youtube.com/get_video_info?video_id=" . $video_id);
parse_str($content, $ytarr);
echo $ytarr['title'];
?>

    So I tried to add it to my previous code (2 is the field ID of the video URL and 7 is the title):

    add_filter("gform_save_field_value", "save_field_value", 10, 4);
function save_field_value($value, $lead, $field, $form){
	global $id;

        //if not the form with fields to encode, just return the unaltered value without checking the fields
        if(absint($form["id"]) <> 1)
                return $value;

        //array of field ids to encode
        $encode_fields = array(2,7);

	parse_str( parse_url( $value, PHP_URL_QUERY ), $my_array_of_vars );
	$id = $my_array_of_vars['v'];

	$content = file_get_contents("https://gdata.youtube.com/feeds/api/videos/".$id);;
	parse_str($content, $ytarr);
	$title = $ytarr['title'];

        //see if the current field id is in the array of fields to encode; encode if so, otherwise return unaltered value
        if(in_array($field["id"],$encode_fields)){
		if(absint($field["id"]) == 2)
                	return $id;
		if(absint($field["id"]) == 7)
			return $videoTitle;
		}
        else
                return $value;
}

    But the title doesn’t work… (The ID does work) What am I doing wrong?
