You should check that what you are passing to foreach is an array by using the is array function   If you are not sure it s going to be an array you can always check using the following PHP example code   if  is array  variable        foreach   variable as  item         do something

This means that you are doing a foreach on something that is not an array   Check out all your foreach statements  and look if the thing before the as  to make sure it is actually an array   Use var dump to dump it    Then fix the one where it isn t an array   How to reproduce this error    lt  php  skipper    abcd   foreach   skipper as  item           the warning happens on this line      print  ok       gt    Make sure  skipper is an array

Because  on whatever line the error is occurring at  you didn t tell us which that is   you re passing something to foreach that is not an array   Look at what you re passing into foreach  determine what it is  with var export   find out why it s not an array    and fix it   Basic  basic debugging
