I was quite suprised when I tested his email
email@example.com and found out that the default WordPress function
is_email() returns false for this type of emails. In other words,
is_email() function isn’t able to validate email addresses with a “+” in it but those are valid email addresses as well as per RFC standard 5322. By the way, if you look at the official documentation of
is_email() function, there also said that it is not RFC compliant.
I had so many requests about multiple image uploads in comments in this tutorial, so I decided to create a separate tutorial specifically about that.
Our goal is to create something like this:
Guys, there are actually two ways of creating a meta box like that, the first way is an easy-breezy way, but you have to install my Simple Fields plugin first, the second way – is to do everything manually from scratch. But please do not worry, no matter what method you choose, I am going to cover both of them in this tutorial.
