In this tutorial we will create Submit Form Data Using Ajax POST Method. This code can compressed multiple files at the same time. PHP is a server-side scripting language designed primarily for web development. Using PHP, you can let your user directly interact with the script and easily to learned its syntax. It is mostly used by a newly coders for its user friendly environment. So let's now do the coding...

Before we get started:

First you have to download & install XAMPP or any local server that run PHP scripts. Here's the link for XAMPP server https://www.apachefriends.org/index.html.

And this is the link for the jquery that i used in this tutorial https://jquery.com/.

Lastly, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.

Creating the database connection

Open your any kind of text editor(notepad++, etc..). Then just copy/paste the code below then name it conn.php.

<?php
$conn

=

new

mysqli(

'localhost'

,

'root'

,

''

,

'db_submit'

)

;
if

(

!

$conn

)

{
die

(

"Error: Failed to connect to database!"

)

;
}
?>

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into your text editor, then save it as index.php.

Creating PHP Query

This code contains the php query of the application. This code will sent the data inputs to the database server by sending ajax post request method. To do that just copy and write this block of codes inside the text editor, then save it as save.php.

<?php
require_once

'conn.php'

;
$firstname

=

$_POST

[

'firstname'

]

;
$lastname

=

$_POST

[

'lastname'

]

;
$address

=

$_POST

[

'address'

]

;
$conn

->

query

(

"INSERT INTO `student` VALUES('', '$firstname

', '$lastname

', '$address

')"

)

;
echo

"Data Inserted!"

;
?>

Creating Ajax Post Script

This is where the code that uses ajax request been used. This code will sent a post request to process the data and successfully to be send to the database. To do this just copy and write these block of codes inside the text editor, then save it as script.js inside the js folder.

$(

document)

.ready

(

function

(

)

{
$(

'#submit'

)

.on

(

'click'

,

function

(

)

{
var

firstname =

$(

'#firstname'

)

.val

(

)

;
var

lastname =

$(

'#lastname'

)

.val

(

)

;
var

address =

$(

'#address'

)

.val

(

)

;
if

(

firstname ==

''

||

lastname ==

''

||

address ==

''

)

{
alert(

"Please complete the required field!"

)

;
}

else

{
$.post

(

'save.php'

,

{

firstname:

firstname,

lastname:

lastname,

address:

address}

,

function

(

data)

{
alert(

data)

;
$(

'#firstname'

)

.val

(

''

)

;
$(

'#lastname'

)

.val

(

''

)

;
$(

'#address'

)

.val

(

''

)

;
}

)

;
}
}

)
}

)

;
