Hi I’m trying to strip whitespaces from a telephone custom field (from options page) in order to set up the telephone number as a telephone link. I’ve tried this but no joy:

  <a href="tel:<?php str_replace(the_field('box_office', 'option'));  ?>" title="Phone our office"><?php the_field('general_info', 'option'); ?></a>

Any help much appreciated.

Hi @ladygeekgeek

There are a few this missing with your above code:
1. You need to echo the str_replace returned value
2. Please use get_field instead of the_field when returning data to a function
3. Please use the $find and $replace parameters in the str_replace function.

Your code should look more like this:

<?php echo str_replace(' ', '', get_field('box_office', 'option')); ?>

Thanks

You are a Star! It works perfectly and I feel like an idiot for leaving out the echo 🙂

Thanks a million
