Don't think there is a way.

Why not create a custom field on the object and put the value of the parameter in there?

I don't think you are able to access url parameters at the trigger level, as a trigger is usually associated with operating database functions.  Also a trigger can be called from contexts where there is no page (from data loader or other triggers etc...).

What is your use case?  There might be another solution.

You can't use these(URL and PageReference) functions in trigger and trigger doesn't have anything to do with URL parameters. These are for ApexClasses only.

Thank you for response, But when i use this URL.getCurrentRequestUrl().toExternalForm() i am getting https://ap1.salesforce.com/001/e in trigger. Thats the reason i want to know how to get query parameter values.

My use case is if i click on standard save button from any standard salesforce page i want to get the full current request url from which page i am inserting/updating that record.

Thanq, i think that would work but just i am trying is there any way to get without creating any field. Anyhow thanx @shyam for quick response.

no problem.

If the value is the same all the time or from a related object, then you could use a formula field to get the value.  Then you can remove it from page layout, so its hidden.
