If your query is successful, PDO::errorInfo() still returns an array. For MySQL 5.x, I get the following...
Array
(
  [0] => 00000
  [1] => 
  [2] => 
)

Seriously errorInfo is your friend. Use it.
If these look like your google searches then you need errorInfo
"no database error showing in php"
"pdo selects from database but wont insert"
"pdo insert not working"
"isnt pdo just a big hype, should I go back to mysql?"
"how much do surgeons make?"
Trust me it will definitely save you hours of insanity if you make it a habit to use it in development. Forget E-ALL, it failed me since well, E-ALL apparently doesn't know that I didn't set a default value in my MySQL table and my query wasnt adding anything to it. So always do this
