Empty wpdb->get_resuts die de execution

The big question is… Why are you using or die() in the first place? I’m guessing that you’re trying to handle erorrs? if so there’s better ways to do it then that.

Hi Catacausic,

Yes, i am handling error. I am using other ways to do it, but i need to understand this because it impacts in many places in may code.

Thanks!

You should be using the built-in error handling, as that will help you out, and it won’t create the same issues that you’re getting now.

The basics behind it is that the or die () part is looking for a true result from the query, and an empty array equates to false so the die() is triggered. Taken directly from the PHP manual:

When converting to boolean, the following values are considered FALSE:

the boolean FALSE itself
the integer 0 (zero)
the float 0.0 (zero)
the empty string, and the string “0”
an array with zero elements
an object with zero member variables (PHP 4 only)
the special type NULL (including unset variables)
SimpleXML objects created from empty tags
