Need help with a php code in a widget [Archive]

Ive been messing with this for some time now. Im trying to use the code in a PHP widget. Ultimately I want to use this to find the hex code from a image then insert the hex code into a field that I can then search my albums with.

For example if the script returns the hex code#000, then that number is automatically filled into the search box of my vb albums and at that point I simply click search and it returns the matching paint colors. So this would be Black paint....

My problem is I cant seem to get it to work because the code has forms in it. Im no coder so Im hoping someone here can help out.

I have the hex search working on my test page. Here...

http://scalemotorcars.com/forum/color_palette_generator/index.php?image=images%2F1322437111.jpg&steps=7&method=precise

This is the source code. Here... http://jrm.cc/color-palette-generator/

Here's the full index.php from the page above. ANY help would be great especially if you know how to search the albums once a hex code is returned.

I should also mention I've already installed a mod that allows for album search. I don't remember the name off hand but its here on vb.org.

Where have you put that code? Into a php widget? You can't have all the html there. You need to assign all the output to the variable $output. It says this at the top of the Configure screen:
Enter Php Code, in the form "$output = <your code>"
