- How to create a ajax based CRUD application step by step.
- How to use bootstrap & Jquery to create an ajax crud application
Here are the Steps for part 3
======================================================
UPDATE
======================================================
Edit functionality
21) Now in this step we will create a javascript function that will fetch info of a record using ajax in json format. And then we will populate this information in edit dialog form. We will use the same dilaog box that we used to create a record but internal form will be different.
22) Create a method called "getRow" in Car_model.php model to fetch a single record from database. Now In CarModel controller we will create a method called "getCarModel" that will return a prepopulated edit form that we will show in edit popup, here we will create a edit.php view, so please see video carefully.
23) Now we will create a "update" method in "Car_model.php" model that will update a record in database using jquery and ajax.
24) Now we will write a function called "updateModel" in "CarModel" controller that will validate & update a record using "update" method of "Car_model.php" model.
25) After updating a record we will show a success notfication using bootstrap modal like we did in adding a record.
======================================================
Delete
======================================================
Delete Functionality
26) In this step we will create "confirmDeleteModel" javascript function that will first ask you a confirmation before delete using bootstrap modal.
27) In bootstrap confirmation modal there will be a "Yes" button, on clicking this button, will run an ajax request that will delete a record from database, but before this we need write a "deleteModel" method in "CarModel" controller that will be called on ajax call, also we need to define a "delete" method in "Car_model.php" model that will delete a record from database.
