我无法在WordPress模板中为字符串添加空格

I try to add space to a string in a WordPress template:

<p class="event"><?php the_field( 'date' ) . " " . the_field( 'lieu' ) . " " . the_field( 'nom_de_levenement' ) ?></p>

The problem is that you are trying to use the fields as strings, but the_field displays the field. You should be using get_field if you need it to return a string instead of displaying it. Once you combine the strings, you can just echo them all at once.

<p class="event"><?php echo get_field('date') . " " . get_field('lieu') . " " . get_field('nom_de_levenement') ?></p>
