.
- <?php
- $conn
=
new
mysqli(
'localhost'

(
!

Creating PHP Query
This code contains the PHP query of the application. This code will update the blog content automatically and will submit the post after completing the post To do that just copy and write this block of codes inside the text editor, then save it as shown below.
save_blog.php
- <?php
- require_once
'conn.php'
;
- if
(
$_POST
[
'blog_id'
]
==
""
)
{
- $title
=
$_POST
[
'title'
]
;
- $content
=
$_POST
[
'content'
]
;
- $conn
->
query
(
"INSERT INTO `blog` VALUE('', '$title
', '$content
', 'Post')"
)
;
- echo
$conn
->
insert_id
;
- }
else
{
- $title
=
$_POST
[
'title'
]
;
- $content
=
$_POST
[
'content'
]
;
- $blog_id
=
$_POST
[
'blog_id'
]
;
- $conn
->
query
(
"UPDATE `blog` SET `blog_title` = '$title
', `blog_content` = '$content
', `status` = 'Post' WHERE `blog_id` = '$blog_id
'"
)
;
- }
- ?>
update_blog.php
- <?php
- require_once
'conn.php'
;
- if
(
$_POST
[
'blog_id'
]
==
""
)
{

' WHERE `blog_id` = '$blog_id
' && `status` = 'Draft'"
)
;
- }
- ?>
Creating jQuery Script
This is where the main function of the application. This code will update the blog content base on the set interval. To do this just copy and write these block of codes inside the text editor, then save it as script.js
.
- $(
document)
.ready
(
function
(
)
{
- var
_autosave;
- $(
'#save'
)
.on
(
'click'
,
function

_autosave)
;
- var
title =
$(
'#title'

;
- var
content =
$(
'#content'

.val
(

;
- var
blog_id =
$(

.val
(

;
- if
(
title !=

&&
