If Else On Php Wordpress-CodePudding

<?php
$genre = get_the_term_list($post->ID, 'genre', '<span >', ', ', '</span>');
$tags = get_the_term_list($post->ID, 'tag-series-movies','<span >', ', ', '</span>');

if($genre,$tags)
    echo '<li>Genre: '. $genre . '</li>';
    echo '<li>Tags: '. $genre . '</li>';
else {
    echo '';
}
?>

Hi. Guys whats wrong of my code? though the code is working 50%. the $genre is working but the else is not working. please help. i want to show the nothing when no genres is not available.

CodePudding user response：

Change if($genre == $genre) to if($genre){

get_the_term_list returns the list or false so you just need to check that $genre is a truthy value

In your current code when $genre is false you are checking if(false == false) which always returns true

EDIT:

you can simplify your code like this

if($genre){
    echo '<li>Genre: '. $genre . '</li>';
}
if($tags){
    echo '<li>Tags: '. $tags . '</li>';
}

There's no need for the else statement as you're not echoing anything
