Hi,

maybe you try it with this

https://www.advancedcustomfields.com/resources/acf-prepare_field/

function my_acf_prepare_field( $field ) {
  $field['value']['url'] = "https";
  return $field;
}

add_filter('acf/prepare_field/key=field_5c6691766a1c2', 'my_acf_prepare_field');

You only need to validate, if there is already a “good” url saved.

Or you take a look here, and find yourself another filter 🙂

thanks, why using [url] and not this ?
$field[‘value’] = ‘https//’;

and the problem is that replace the existing content, i need that add ‘https’ only if the field is empty.
thanks

Hi,

i used $field[‘value’][‘url’] = “https”; because in my quck test it seems right.

And the other Problem, yeah, thats what i meant with

“if there is already a “good” url saved.”

You have to validate inside the function if $field[‘value’][‘url’] is already a valid url.

Should be something like these

if($field[‘value’][‘url’] != valid url){
//no valid url, fill the field with https/http
$field[‘value’][‘url’] = “https”;
}else{
//already a valid url here, nothing to do
}

return $field;

Sry, im not a php developer, but if you google for “php validate url” you should find something, thats fit.

I think this could work here: https://stackoverflow.com/questions/7003416/validating-a-url-in-php

@pipoulito You might try entering https:// as the default value and placeholder for a link in the field group editor, rather than this JS solution after the fact.
