The Ninja Forms nf sub table columns hook.

Description

apply_filters( 'nf_sub_table_columns', (unknown) $cols, (unknown) $form_id ); 

Parameters (2)

The cols.

1. $form_id (unknown)

Usage

To run the hook, copy the example below.

$cols = apply_filters( 'nf_sub_table_columns', $cols, $form_id ); 
                         
if ( !empty( $cols ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

// define the nf_sub_table_columns callback 
function filter_nf_sub_table_columns( $cols, $form_id ) { 
    // make filter magic happen here... 
    return $cols; 
}; 
         
// add the filter 
add_filter( 'nf_sub_table_columns', 'filter_nf_sub_table_columns', 10, 2 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'nf_sub_table_columns', 'filter_nf_sub_table_columns', 10, 2 );
