isset issue

[CyberShot]

I am working in WordPress. I have building a widget. I have it set right now to say that

$intro = ! empty( $instance['intro'] ) ? esc_attr($instance['intro']) : '';

Right now, $intro is an empty string and in my widget, for the output, I have

$intro = isset($instance['intro']);

So, when I dump $intro, I says "Bool : true". I see that isset does set it to true when it's an empty string. My problem is that my variable is echoing out "1" right now when it should be blank. I have tried a few different things to get it to be blank. Here is my latest attempt

<?php if ( $intro == '') { 
	return;
} else { 
	echo '<p>' . $intro . '</p>'; 
	}
} ?> 

no matter what I do, $intro is echoing 1. What am I missing here?

With the second line, $intro is a boolean value. True or false. The string representation of true is "1" and of false is "".

 

You should probably be using a ternary like in the first line.
