It happens when  ret hasn t been defined  The solution is simple  Right above  tags   get tags     add the following line    ret   array

User · Answer

You are getting the error because  ret is not an array   To get rid of the error  at the start of your function  define it with this line   ret   array     It appears that the get tags   call is returning nothing  so the foreach is not run  which means that  ret isn t defined
