May I know why I cannot submit my search function by pressing enter? When I enter the primary key and press enter, it will show this :
Notice: Undefined index: submit in c:\easyphp1-8\www\efiling\accountingdeleteprocess.php on line 23
But if I enter the primary key and press the submit button, there is no error. May I know how to make it can search by pressing enter?
Below is my coding :
