Potty readiness actually depends on three areas of maturation: neurological (recognizing signals in time), physical (ability to hold it long enough to get to the potty) and emotional (a desire to make this huge step).Here's one of several sites that gives some great "readiness" checklists, plus the skinny on the various approaches to potty-training, their advantages and challenges. See if you can find your situation here: http://www.parentingscience.com/toilet-training-readiness...
Potty training is ultimately a process that the child must control, or else she's simply not trained.
Additionally, night training is a whole separate step for many children, and can lag a year (or several) behind day training. It's not too unusual for third or fourth graders to need diapers at night, and for a few unfortunate kids, they reach adolescence before they stop bedwetting. Their sleep is too heavy for the full-bladder signal to get through, and/or the sphincter isn't strong enough to hold a full bladder. (This is more common in boys.) They really are not doing this on purpose, and many of them are horrified and ashamed of not being able to stay dry through the night.
Sometimes rewards work in the short run if only motivation is lacking. But that introduces the very real possibility that rewards/bribes will need to escalate to keep the child "motivated," and that is a mistake that you will seriously regret someday.
So, what I would suggest is that, as hard as this will be, you drop your expectations, tell your daughter you are proud of how well she's growing up, and express your confidence that she will use the potty when she's ready. That may be when she notices that taking a few minutes to go to the bathroom will be easier than getting changed. And then just stop hinting, fussing, reminding, nagging, demanding, bribing, acting anxious or annoyed, or anything that you MIGHT currently be doing around the topic of potty training.
Kids WANT to make this developmental step when they're ready, just as they want to walk and talk when they're ready. Your daughter will probably need some "space" to work it through for herself. Or she may need a few more weeks or months. Even if that's the case, that's a few more weeks or months of you having to clean up after accidents. Many parents skip that aggravation altogether by waiting for the child to decide to be trained – at which point, the feat is often accomplished in only a day or a week.
Meanwhile, you can continue to make all your messages about using the bathroom as positive as possible. That can include modeling how easy/quick it is for you, reading potty books or watching potty videos, having her toys/stuffed animals role-play pottying, and in general making a game of it. With my grandson, once he could do it but didn't want to take the time, I would go into the bathroom and begin noisily ejecting all the dinosaurs that were crowding the room and sitting all over the toilet seat. My grandson couldn't resist that game, and would come in and help me wrestle the beasts, and claim his spot on the toilet.
