In Web development file or image upload is a very required feature. There are many ways we can store images. One we can upload image on server and store image name in Mysql database using PHP. In another way we can directly store images in Mysql database table using PHP also. There are many post we have publish on upload single image or multiple images on server and store image details in database using PHP. But in this post we have convered one advance topic like how to insert multiple image in mysql database using PHP with Ajax.
In one of our previous post we have step by step describe how to insert and fetch images from Mysql database using PHP. But in that post we have use only PHP script for insert image into mysql database and then after fetch images from Mysql database and display on web page using PHP. But here we have make one form with option like select multiple images at the same time and by using jQuery Ajax send that images data to PHP. In PHP script it will convert image into binary string format and insert into Mysql database one by one. After inserting multiple images into Mysql database, now we want to retrieve images from mysql database and display on web page. For this also we have use jQuery and Ajax function which send request to PHP, at PHP script that fetch data from mysql table and convert that data into html format and send back to ajax request. Now we have discuss source of How to Upload Multiple Images in Database using PHP Ajax.
