BBC Sports:
Barnsley boss Valerien Ismael said:
"It's clear to see that we're on the right path at the moment. We controlled the game and took the fight to them.
"If you give Cardiff a set-piece, then it's like giving away a penalty and they're very difficult to defend.
"We fought hard but lost the control of the game. Cardiff came from nowhere and we made mistakes.
"It's a mixed feeling tonight. We need to be more clinical but it's another learning process for the guys."
Cardiff boss Mick McCarthy told BBC Sport Wales:
"I'm delighted with the point today. We can all learn a little bit from a committed and determined Barnsley.
"The way we came back and responded, I'd say we fought fire with fire.
"We will only succeed together, and we showed a real willingness tonight to get a point out of the game. Hopefully the result will give them a shot of confidence.
"There are parts of the game that Barnsley dominated, but I have to give my players real credit for fighting back.
"It was such a tough game and they all had to stand up to it. We scrapped out a really good point today."
