    Hello friends,

    Can someone give me a little help?

    I have this code:
    if(get_field( "nofollow_tag" )) { $nofollow_tag = 'rel="nofollow noopener"'; } else { $nofollow_tag = ''; }
    PHP:
    And now I need to add this code to show the value:
    <?php echo $nofollow_tag; ?>
    PHP:
    The idea is to show in this line:
    Since that code is already between php tags, how can I replace the #CODEHERE# with my code?
    My php knowledge is very poor to do this... probably I need to create a variable right?

    Thanks!!

    you can put your code after $href in your output variable.

    Eg. $href,$nofollow_tag,

    ... and people wonder why I call sprintf halfwit garbage that's a remnant of early C compilers being useless single-pass rubbish that has ZERO place in modern code. STOP making the parser work twice as hard as it has to!

    
    <?php
    $output = 
    	'<a class="link" ' .
    	$site_icon .
    	' href="' . $target . '"' .
    	$nofollow_tag  . '>' .
    	$title . ' ' .
    	$sticky_icon . ' ' .
    	$additional_icon . ' ' .
    	$mobile . ' ' .
    	$new_icon . ' ' .
    	$extra . ' ' .
    	$hover . '</a>' .
    	$review;
    ?>
    
    Code (markup):
    Of course if you are only using that nofollow_tag variable once, don't waste a 'variable for nothing' on it -- and even if you were, ternary operators are your friend. Makes me wonder just how many 'variables for nothing' you've got that vomiting up in there.

    
    <?php
    $output = 
    	'<a class="link" ' .
    	$site_icon .
    	' href="' . $target . '"' .
    	(get_field( "nofollow_tag" ) ? ' rel="nofollow noopener"' : '' ) .
    	'>' .
    	$title . ' ' .
    	$sticky_icon . ' ' .
    	$additional_icon . ' ' .
    	$mobile . ' ' .
    	$new_icon . ' ' .
    	$extra . ' ' .
    	$hover . '</a>' .
    	$review;
    ?>
    Code (markup):
    Loses the variable for nothing and does the comparison right there in the $output creation.

    Either way, 99.99% of the time you see sprintF, somebody is horribly overthinking something simple.
