pre_get_col_charset filter-hook . WP 4.2.0
Filters the column charset value before the DB is checked.
Passing a non-null value to the filter will short-circuit checking the DB for the charset, returning that value instead.
Usage
add_filter( 'pre_get_col_charset', 'filter_function_name_1793', 10, 3 ); function filter_function_name_1793( $charset, $table, $column ){ // filter... return $charset; }
- $charset(string)
- The character set to use.
Default: null - $table(string)
- The name of the table being checked.
- $column(string)
- The name of the column being checked.
