HTML not showing inside IF statement (Wordpress)

Question

I have the following problem. I am using Advanced Custom Fields for Wordpress to create a subtitle field for a post. I like to give this subtitle some styling but my HTML code within the IF-statement doesn't show on the page. The $subtitle does show.

<?php $subtitle = the_field('subtitle'); ?>
<?php if(strlen(trim($subtitle)) > 0): ?>
  <div class="post-sub-title"><?php $subtitle; ?></div>
<?php endif; ?>

I spent hours searching for similar problems but couldn't find any solutions. So this must probably be a rookie mistake on my part.

Solution

<?php $subtitle = get_field('subtitle'); ?>
<?php if(strlen(trim($subtitle)) > 0): ?>
  <div class="post-sub-title"><?php $subtitle; ?></div>
<?php endif; ?>

Changed the_field() to get_field(). Kuddo's to Aditya Vikas!

You should echo/print it (The subtitle variable).

<div class="post-sub-title"><?php echo $subtitle; ?></div>

Ok thank you for your response but this doesn't fix the problem for the HTML not being shown.

Then I guess the length of the data in subtitle is not greater than zero after trim function is called. Or you must have a bug somewhere else in your code, not the part you provided. Edit: Try print it without using the if statement and see if it can print.

try using this piece of code :

<?php if(strlen(trim($subtitle)) > 0): ?>
  <div class="post-sub-title"><?=$subtitle?></div>
<?php endif; ?>

instead of this :

<?php if(strlen(trim($subtitle)) > 0): ?>
  <div class="post-sub-title"><?php $subtitle; ?></div>
<?php endif; ?>

and also one more thing !

the_field() is not a default WordPress function

the 'whatever' plugin you are using might have a corresponding function:

get_field()

I tried what you suggested. But it didn't work. The <div> still doesn't show. Only the variable $subtitle (wich contains some plain text) does.

Changing the the_field() to get_field() fixed to problem! Thank you very much!

try this one:

<?php $subtitle = get_field('subtitle'); ?>
<?php if(!empty(trim($subtitle))): ?>
  <div class="post-sub-title"><?php $subtitle; ?></div>
<?php endif; ?>

Thanks.
