Failed to load in else condition-CodePudding

I need to embedd video to my loop with condition. I try this code:

 <?php if (function_exists("wp_oembed_get")) {
 $url = esc_url( get_post_meta( get_the_ID(), 'wiki_test_embed', 1 ) );
 echo wp_oembed_get( $url );
 } else{    ?>
    No Video Here
 <?php
 }
 ?>

Everything work fine when videpinserted to the post, but when the post have no video, the text "No Video Here" doesnt appear.

Really appreciate for any helps.

Your code is checking whether the function, wp_oembed_get(), exists. That should be true regardless of whether your post contains a video or not. You'll never hit the else statement.

Instead of checking for the existence of a function, you need to be evaluating the value of your meta field. Example:

if ( $video_url = get_post_meta( get_the_ID(), 'wiki_test_embed', true ) ) {
    echo wp_oembed_get( esc_url( $video_url ) );
} else {
    echo 'No video was found.';
}

It seems like you are using the <?php tag in a way that you are cutting the if else condition. Try this.

 <?php 
 
 if(function_exists("wp_oembed_get")) {
    $url = esc_url( get_post_meta( get_the_ID(), 'wiki_test_embed', 1 ) );
    echo wp_oembed_get( $url );
 } else{   
    echo( 'No Video Here' );
 }
 
 ?>
