 This has a syntax error. You're starting a for loop but trying to end it
 as a foreach loop. That last line should be `endfor;`.

 You're also starting the for loop at 1 and ending with i equal to 3. This
 means that it's attempting to grab custom_field_1 to custom_field_3
 instead of 0 to 2. You want `for ($i = 0; $i <= 2; $i++) ...`
