Database operation class-front-end easyui-datagrid,form (php) introduction, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

Implement the function:

The datagrid on the left displays brief information, the right shows the details of the selected row, and the database adds, deletes and modifies.

(1) Click the selected row, and the details are displayed on the right. The "add", "modify" and "Delete" buttons are available, and the "Save" button is disabled.

(2) Click the "add" button, "modify", "Delete" button to disable, and "Save" button to enable.

(3) Click the "modify" button, "add" and "Delete" button to disable

Difficulty: insert method and update method in general database operation class

Final effect picture:

The front-end function is not perfect, there is still a problem with the logic between the buttons, and finally add the front-end code.

Formain.php judges the value of the front end, and calls actSQL.class.php to get the result.

The code is relatively simple.
