ajax submit form to database instance

Submitting a form to the database on a static page is very simple.

<form action="test.php" method="post">
</form>

The disadvantage is that the page will be refreshed and the page will jump. The technology I bring to you today is the ajax form submission. The advantage is that it does not refresh the page, does not jump to the page, and is submitted silently.

First we have to have a form submission page:

index.html
This page consists of two parts
1. Form control
2.jQuery+ajax Processing script
The jQuery script will obtain the form form data and submit it to api.php through post

The following is the form receiving page
api.php
This page is actually very simple
Just connect to the database
Then insert into the database
The two values ​​inserted into the database are
title and url

17154344e9e2a6fb548e020bf5ec4cb0

Then we need to create a database
The database is named test, and the table Named testdata

The following is a screenshot of the database

At this point, this case is completed.
Of course, the above code simply implements the ajax form submission.
But there are still many details that need to be optimized, such as form verification, data encryption, etc. You can expand, learn and improve by yourself.
