21606,term_exists returns 0 and null,barrykooij,barrykooij,"The function ''term_exists'' in ''wp-includes/taxonomy.php'' has two different return values, ''0'' and ''null''. The function does a few checks and returns ''0'' if the condition of the check is not met. If the checks are met, the return value will be the result of a ''$wpdb->get_row'' or ''$wpdb->get_var''. If the term is not found in the database the methods ''get_row'' and ''get_var'' will return ''null''.

Because of the different type of return values it's not possible to do a strict check on the return value to see if a term was found. I've changed the return ''0'' in ''term_exists'' to return ''null'', so that if there is no term found the result of ''term_exists'' will always be ''null''.",defect (bug),new,normal,Future Release,Taxonomy,3.4.1,normal,,has-patch,
