Basic question, I'm sure this has been answered before. But since I'm not familiar with PHP I don't know what to search for, hence the title of this question.
This code outputs 'my custom field value'
$title = stripslashes($_POST['user-submitted-customfield']);
I'd like to make it 'my custom value from @mysite', something like
$title = stripslashes($_POST['user-submitted-customfield']) + from + @mysite;
which I tried and returned an error
