forget about the code above, i have made some changes, now I can save both thumbnail and original image into folder, but i can only save the original image name into data base. I think the problem is thumbnail code is within a class, and insert into code is outside of the class, see the red line.

 

 

<?php

require_once('db.php');

$address = $_POST[house_address];

class resizeimage

{

        var $type;

        var $width;

        var $height;

        var $resize_width;

Well, need some details first. What table is the thumbnail being saved into, what fields do you have in the table?

 

table name is house, there is address,thumb,imagedata1,imagedata, address is the primary key, thumb is just a number, imagedata1 is thumbnail and imagedata is original image

I'm sorry, I really don't follow this. Is it your class, have you written it yourself, or are you using someone elses. It's not a difficult task, but the database isn't making sense with what you're doing.

 

I am making an image upload function, when people submit an image, it will be auto resized, and save both resized image(thumbnail) and original image into folder which is on the server, and save the modified image name into database, which is 'imagedata1' and 'imagedata'.

 

these codes are from someone google, it works fine, except it couldnt save the resized image(thumbnail) into database.
