strip_tags() expects parameter 1 to be string - error

Question

After months of use my application form suddenly stopped with this error:

Warning: strip_tags() expects parameter 1 to be string, array given in /home/useraccoun         


        

Answer 1

Well, it's obvious - your $_POST[$key] as array and not string. So you need to decide what do do in terms of logic of your application. I can suggest:

if(is_scalar($_POST['$key']))
{
   //treat any scalar value as string and do stuff:
   $post->{$key} = trim(strip_tags($_POST[$key]));
}
else
{
   //here you need to decide what to do with such things as arrays
}
