1) The thing you downloaded is the JavaScript only. You also need the PHP class and some additional JavaScript to make it work in SilverStripe. Download it from my site: http://bummzack.ch/colorpicker (scroll down and download colorpicker.zip).

2) dev/build is something quite fundamental when developing with SilverStripe. You have to do it whenever you add new modules or own page-classes to your website. Basically you just append /dev/build to the URL where SilverStripe is installed. So if SilverStripe is installed in http://localhost/silverstripe, it would be http://localhost/silverstripe/dev/build.
I think you should really have a look at the SilverStripe tutorials.. it's all explained there: http://doc.silverstripe.org/doku.php?id=tutorials

hi, banal

Thanks for your replying. I am new to silverstripe ,

I just downed the new "colorpicker.zip" from your site: http://bummzack.ch/colorpicker

after unzip the colorpicker.zip file, I saw this folder has 2 folders, "__MACOSX" and "colorpicker" folder, I did to uploaded the ""colorpicker" folder to my silverstripe site Directory.

and create a new ColorPage.php File, uploaded , then run dev/build by use: http://www.mysiteurl.com/dev/build)

site auto forward to http://www.mysiteurl.com/Security/login

my site still down, I don't know why .

Please check my new "ColorPage.php" file below

Thanks

/dev/build requires a login if your website is live.
Either login, or if you can't do that due to the Error, add the following to mysite/_config.php

Director::set_environment_type('dev');

Then you should be able to run /dev/build without login.
Your colorpage looks fine.

yes, banal

I just edited the file mysite/_config.php with code below:

Director::set_environment_type('dev');

after uploaded the file "_config.php" ,then run dev/build by use: http://www.mysiteurl.com/dev/build

It take me to:

Environment Builder (formerly db/build)
...
...
Creating database tables
...
Creating database records

My site has been back to live, after I logined to my admin CP -site content,

I can't see the "colorpicker" Module , I am not be able to edit color to my content.

how to activation the "colorpicker" Module ?

Thanks

The colorpicker module just adds a new field to the SilverStripe form fields.
If you create a new "Color Page" in the CMS you should be able to select a color on the color field you added there...

hi,

banal, I just created a page by choose" Color Page" , then click" Go"

It take me to "Content creating"

I can not see any color button and color words.

thanks

Do you see the text-field labeled "Background Color"? If you click on it, the color selector should appear.
