php - TRIGGER CREATED successfully , but no triggers in information_schema TRIGGERS table -

Hi, I'm trying to use the trigger, my MySQL version is 5.5.8

This is when I'm creating a trigger, PHPMadmin says it has been created successfully,

This is my trigger

  DELIMITER $$ INSTORE before the 'triggers' check_pipil_apaign' for every line, if it starts at `pupil_data`, CHAR_LENGTH (new.Defferth) & lt; 4 THEN SIGNAL SQLSTATE '12345' SET MESSAGE_TEXT: = 'Check interruption on pupil_data. Debtoffbirth failed '; end if; END $$ DELIMITER;   
 It says that  
  your SQL query has been executed successfully DELIMITER create $$ trigger 'check_pipil' before leaving 'for each line' Before signing the pupil_data`, CHAR_LENGTH (New. Datfurth) & lt; 4 THEN signal SQLSTATE '12345' SET MESSAGE_TEXT: = 'Check interruption on pupil_data. Debt failure failed '; end if ;   
 But when I select from  
  info_schema.triggers * MySQL returned an empty result set (i.e. zero lines). (Query took 0.0843 seconds) SELECT * info_schema.triggers LIMIT from 0, 30   
 Why this is happening, please help me, thanks in advance.
