PHP添加类HT​​ML DIV(PHP add class to html div)

我想一个类添加到我的HTML（.complete）用PHP：

if( get_field('to-do-repeater') )
{
    Add (complete) class to <div class="to-do to-do-wrap"> should be <div class="to-do to-do-wrap complete">
}
else
{
    Do nothing
}

Answer 1:

试试这个代码：

<div class="to-do to-do-wrap<?php echo get_field('to-do-repeater') ? ' complete' : '' ?>"></div>

Answer 2:

<?php

echo "<div class=\"to-do to-do-wrap ";
if(get_field('to-do-repeater'))
{
    echo "complete";
}
echo " \"></div>";

?>
