QDateTime::fromString
QDateTime::toString

I've tried the 2 methods you mention above. but it can't be converted. this is the code :

QDateTime date;
    date = QDateTime::fromString(ui->lineEditLahir->text(),"yyyyMMdd");
    qDebug()<<date;

QDateTime date;
    date = QDateTime::fromString(ui->lineEditLahir->text(),"yyyyMMdd");
    qDebug()<<date;

To copy to clipboard, switch view to plain text mode 

this is the build result : QDateTime("")

QDatetime::toString() is not function for me, because what i'm trying to do is convert a String from line edit where user input it. the string format is like a date format, eg : 13-01-2012 (dd-MM-yyyy) and i want to convert the string into yyyy-MM-dd for storing it on database.

At first, let's clear up what kind of data do you want to input and how this should look like in the database. Just show a sample.

Database (MySQL) only accept data in date yyyy-mm-dd format, it couldn't accept the dd-mm-yyyy format where i have a lineedit which takes user input and i have set input mask to the line edit (just like the picture below). So, in order to save it, i must convert it to the database acceptance format : yyyy-mm-dd. The question is : how can i convert the dd-mm-yyyy format (which i get from a lineedit) to the database acceptance format ?

this is the data :
Untitled.jpg

this is the database format :
Untitled.jpg

QDateTime dt1 = QDateTime::fromString("12-12-2012", "dd-MM-yyyy");
qDebug() << dt1.toString("yyyy-MM-dd");

What if the user change the date on the lineedit ???

everytime user input to the lineedit must be convert it, are the above code can do that ?

[mentalmushroom]

as far as i understood, the database is updated when a user clicks submit. if so, connect clicked signal to some submit slot and do the conversion in that slot.
