CodeIgniter - How to check if there is anything in the validation_error array

Question

I'm wanting to display a general error message if there are any errors in the validation_errors() array, but if I do something like

if(isset(validation_errors())) { echo 'error'; }

then it returns back and says:

Fatal error: Can't use function return value in write context

Any help would be grand.

if(validation_errors() != false) { echo 'error'; }

isset is used to Determine if a variable is set and is not NULL

Just echo vadidation_errors()

It will output if there are errors, and nothing if no errors. You don't need if

What if you want to contain the errors in a div. Not each individual divs, but a wrapping div. In that case you need an if statement

@jsheffers You can specify the wrappers in the function params: validation_errors('<div>', '</div>')
