Ad_ID int FK

so how insert image into above table using codeigniter thanx in advance

Answer 1

You should avoid saving images and binary files to the database. Just save the path to the file in the database.

If you still want to to that:

Base64 encode(to avoid escaping, that may harm your data) the image data and put it into the field, like you would do with any other data.

 <?php

 $pathToImage = '/abc/img.jpg';

 // not sure about codeigniter syntax, but you should understand whatis meant. 
$table->image =
base64_encode(file_get_contents($pathToImage)); 
$table->save();

Don't forget to decode the data on your way back.

Ref:

base64_encode

base64_decode
