How to get multiple responses from a PHP file via AJAX?

Question

My PHP file performs 2 operations: 1. sends data from the form to the database table, 2. sends email.

What I want to do is show status messages via ajax. For example, “The first operation completed, please wait a second,” and then when the second operation is completed, the following message “The second operation completed too” will appear. Now my Ajax looks like this.

How can i change this?

//add status data to form form.data('formstatus', 'submitting'); if (validate()) { //send data to server for validation $.ajax({ url: formUrl, type: formMethod, dataType: "json", data: formData, success: function (data) { $.notifyBar({ cls: data.status, html: data.message }); form.data('formstatus', 'idle'); } }); } 

Answer 1

in success block, you can make another ajax call. This is the simplest. You can do this in .success (),. AjaxSucces () ,. complete () or .then () as follows: $ .ajax (...). Success (...);

Ideally, you should embed code in a function like

 $.ajax({ url: formUrl, type: formMethod, dataType: "json", data: formData, success: function (data) { notifyResponse(data); form.data('formstatus', 'idle'); sendMail(); } }); function sendMail() { $.get(mailUrl, function(data) { // or $.post(... notifyResponse(data); }); } function notifyResponse(data) { $.notifyBar({ cls: data.status, html: data.message }); } 

Answer 2

If you need to perform two operations with different runtimes, just send two different AJAX requests and get answers from them.

Divide your PHP service in two. If the second part depends on the first, instead of sending two requests at the same time, send the second request when the first returns.

In other words, in your success callback, you must notify the user of the completion of the first operation, and you proceed to call the second operation, whose success callback indicates that the second operation is completed.

Another approach, different from the proposed steve, is to use a kind of long survey similar to the one explained in this answer:

Not so simple and with a more complex server configuration.
