Hi,
I like to add a ACF to my Posts where I can add a SCRIPT from GetYourGuide to the HEAD if necessary.
For this I have created a new ACF field “get_your_guide_script” with the rule “all posts”
Then I have added the following code to my functions.php
/* Add GetYourGuide Script to HEAD */
function acf_header_script() {
$schema = get_field('get_your_guide_script');
echo get_field('get_your_guide_script');
}
add_action ( 'wp_head', 'acf_header_script' );
I don´t know if this is the correct way – but i works 🙂
Now it happens in posts that I want to leave the GetYourGuide field empty, because I don’t want to include GetYourGuide in the post. Then the code in the function.php makes no sense.
Is it possible to extend the code above with a query like:
If get_your_guide_script in a post = empty, then include nothing in HEAD?
You code should output nothing if the field is empty.
