Verifying initials

[squaringkarma]

Hi again. What's a common way of verifying someone has entered their initials? My thought process was this:

• Person enters their name in three separate fields on a form: First Name, Middle Initial, and Last Name.
  
• [other fields not relating to this question.]
  
• Person enters their initials in a field called Initials. If they didn't enter a Middle Initial, I ask them to enter in an * where it would be.
  
• I would then take a substring of the First Name, Middle Initial, and Last Name fields and put them into an array. If they didn't enter a Middle Initial, I would somehow put the default value of that substring as an *.
  
• I would then use implode to convert the array to a string.
  
• Then I would compare the new string to the value of the field Initials.

 

...But I was wondering if there was a simpler/more intuitive way of doing the task. Hopefully my way made sense?

Sounds fine, but I think you can probably skip the array step
