我可以在使用 jquery ajax 的表单提交上同时调用同一 php 页面上的方法，也可以同时调用另一个 php 代码中的方法吗？

Question

help me! I am a php rookie and i am confused with the php request.

Working on MVC structure for view, I created a HTML form, and on form submit i want to do call two different methods sendMail() and validateData() available in two different controllers (php file) - say one in process.php and another in register.php .

On form submit first I want to validate the data and save data to database using validatedata() . Then I want to send a verification mail to the user using sendMail() .

To handle the request (click event) I am using jquery ajax. Ajax takes a single URL for posting data to the specified URL. So how can I make two different URL requests in a single Ajax call, or say how can I call both the methods in a single Ajax call? Please suggest me what i should do to solve this issue? thanks in advance.

Answer 1

A controller should handle an entire request.

So if the user makes (for example) a request asking to create a new user account then a single controller should:

1. Validate the data the user has sent to make sure it is what is required before creating an account
2. Create the account in the database
3. Send the email
4. Return a response saying if it worked or if there was an error

So you'll end up with something like

{
    $errors = validateData($_POST);
    if ($errors) {
        echo generateErrorPage($errors);
        exit;
    }
    $result = createUserInDBAndSendEmail($_POST);
    showSuccessPage($result);
}

(That's very rough and ready for the sake of example).

Don't divide the steps you need to do to complete the task up between different controllers. Then you only have one URL to worry about.

You can divide the functions up between different files and then include them.

The complete process for creating a user might require additional feedback from the client, eg

1. Client makes a request to the CreateUser controller
2. Server creates a user in "unconfirmed" state, sends email to the user and returns an HTML page telling them to check their email
3. User clicks a link in the email to make a request to the ConfirmEmail conroller
4. Server changes the user to "confirmed" and returns a logged in homepage with a welcome message

… and in that case it would have multiple controllers since you need the user to make two different requests.
