Hello, can you help me please. I want get the custom field in functions file. What is the best approach?
The next no work for me
function query_crm_usados_interna(){ $meta = rwmb_meta( 'if_usados_usad_id',get_the_ID() ) return $meta; }
Hi,
If you needn't the extra arguments, please leave the second argument empty.
function query_crm_usados_interna(){ $meta = rwmb_meta( 'if_usados_usad_id', '', get_the_ID() ) return $meta; }
Get more details in the documentation https://docs.metabox.io/rwmb-meta/#arguments.
Hello, thank you for your answer, but this code doesn't work in functions.php I am reading and the get_the_id() function only work in the loop, and I am not using the loop. maybe can you help me please?
If you do not use the function in the loop, just add a parameter to the function like the helper function.
function query_crm_usados_interna( $post_id ){ $meta = rwmb_meta( 'if_usados_usad_id', '', $post_id ) return $meta; }
then pass the post ID when calling the function
echo query_crm_usados_interna( 1234 );
.
