John Daly's Ex-Wife Arrested ... But What's She So Happy About?

1:45 PM PT -- Sherrie is now being held without bail, and the D.A's Office says she'll be behind bars for several months. We're told she failed to appear for a prior family court case, so a judge remanded her bail until her first hearing in that case ... which is November 4th.

Smile, Sherrie Daly ... you've just been tossed behind bars!!!

Golfer John Daly's ex-wife was jailed Friday in Memphis, TN because their teenage son missed too much school without an excuse.

The Shelby County DA tells TMZ Sports the boy missed more than 15 days, without an excuse, during two separate periods: August 2012 - February 2013 and August 2013 - February 2014.

Daly was booked on multiple charges of contributing to the delinquency of a minor, a misdemeanor. She will go before a judge on Monday and could get sentenced to almost a year behind bars.
