具有OR条件的多个WordPress类别IF不起作用

Question

I wanted to select one of 3 or more conditional statement, but I can't get it work as intended. It showing "Game title: 1". Here is the code I'm using:

<?php echo "<strong>Game Title: </strong>";
    if( $info = get_field('pcgame_name') || get_field('psppublisher') || get_field('ps3game_name') ) { ?>
        <?php echo $info;?>
    <?php } ?>

Answer 1

A single "=" is an assignment ie making $info = 1 (because one or more of the functions is returning True/1). You use "==" to check for equality so you probably want:

<?php echo "<strong>Game Title: </strong>";
if( $info == get_field('pcgame_name') || $info == get_field('psppublisher') || $info == get_field('ps3game_name') ) { ?>
    <?php echo $info;?>
<?php } ?>

Edit: If you are not trying to compare a value with $info but instead trying to echo the value of the first non-empty ACF field then try this:

<?php echo "<strong>Game Title: </strong>";
   $info =  get_field('pcgame_name');
   if (empty($info)) $info = get_field('psppublisher');
   if (empty($info)) $info = get_field('ps3game_name');
   echo $info;
?>
