PHP form to insert data into the database table

Hi Experts:

I have a MySQL table with 7 columns - id, title, description, type and image1, image2, image3.  I need help on creating a form to enter the data on a webpage and insert into the table with id as the primary key which auto_increments.  With options to upload 3 images with a single form.

Thanks,

This expert suggested creating a Gigs project.
There are several examples in the basic documentation for PHP.  If you're new to the language, you might want to get started learning here:
https://www.experts-exchange.com/articles/11769/And-by-the-way-I-am-New-to-PHP.html

Here is an example showing a design pattern of PHP and MySQL table maintenance.
https://www.experts-exchange.com/articles/12335/PHP-and-MySQLi-Table-Maintenance.html

Here is the explanation (with code samples) of why we avoid MySQL and choose MySQLi or PDO.
https://www.experts-exchange.com/articles/11177/PHP-MySQL-Deprecated-as-of-PHP-5-5-0.html

Here is a teaching example script showing how to upload images.

    INPUT NAME= IN TYPE=FILE DETERMINES THE NAME YOU FIND IN _FILES ARRAY

Tying all these things together into an application might be something you could use some help with.  If so, consider using E-E Gigs to work with a professional, hands-on.
