Visualforce - Beyond Basics Series 9 - Quick way to check page access

What is page access ?

In salesforce, we can apply security to visualforce pages based on profiles.

How to enforce them in visualforce ?

It's is enforced automatically when user tries the access the restricted page. But, if you want to identify the access before you redirect the user, there's a solution for that.

How to do that ?

Apex profile getContent() method on PageReference class. This applies the profile permissions before returning the content. So, we could use that to determine the access.

Where is the code ?

For illustration, i have given a textbox to accept the page name & then check the access based on that.

	public class testcls9_08122016 {
	public string pageName { get; set; }
	public Boolean getHasAccess() {
	try {
	PageReference newPage = new PageReference('/apex/'+pageName);
	newPage.getContent();
	} catch(Exception e) {
	return False;
	}
	return True;
	}
	}
