Question

<?php
if(get_field('member_only_content')){
    echo "do something";
}else{
    echo "do something else";
}
?>

How do I insert HTML code where it says "do something"? When removing echo "do something"; and pasting the HTML code the WordPress site crashes.

Answer 1

That would be because you placed the HTML code within php tags (<?php ?>). Text inside this tag is interpreted as a PHP instruction, thus it won’t render HTML. There are 2 general ways render the HTML in a PHP file:

Echo the HTML

<?php

    if (get_field ('member_only_content')) {
        echo "<span>Put HTML here</span>";
    }
    else {
        echo "<span>Put HTML here</span>";
    }
?>

Place the HTML Outside PHP Tags

<?php if (get_field ('member_only_content')): ?>
    <span>Put HTML here</span>
<?php else: ?>
    <span>Put HTML here</span>
<?php endif;?>
