I would like to preload custom values to a front-end form made with acf_form() function.
Is there any way to accomplish this without javascript?
Thanks in advance!

Hi @japel
You can use a filter called acf/load_field to hook in and modify the value of the $field.
Docs can be found here:

Hi elliot!
Thank you, that sounds nice!
Kind of embarrassing, you know how I tried to help myself?
I started using ob_start() and loaded the rendered form to a string, and then replaced the values using str_replace() 😛
This sounds a bit more elegant 😛
Thanks!

Hi elliot,
I tried using that filter, but it just don’t hook. 🙁
acf/load_value works fine and hooks but if I try using acf/load_field it just doesn’t hook.
What could I be doing wrong?
Best regards,
Jan
my bad, my bad! got it working… it was an xdebug problem… sorry!
Dear elliot,
now I have another question regarding checkbox values.
I’m saving acf form data with ajax to postmeta, for a checkbox field with two checkboxes
value, anothervalue
the data stored by acf if both are checked is:
a:2{i:0;s:5:”value”;i:1;s:12:”anothervalue”;}
when I reload the page, retrieving postmeta and
set $field[‘value’] to a:2{i:0;s:5:”value”;i:1;s:12:”anothervalue”;}
the checkboxes are not checked 🙁
what am I doing wrong here?
Thank you and best regards,
Jan
Hi @japel
In the database, the value saves as a:2{i:0;s:5:”value”;i:1;s:12:”anothervalue”;}. This is technically a string, but when WP loads the value, it converts it to an array!
When you update your value, don’t update it with a string, update it with an array.
The array should contain the values such as “value” and “anothervalue”
Let me know if you need any extra help.
