I have a form :
Like required felds error message , I would oblige user to put 6 digit code in the field "numero de symbole" . if he doesn't validate this condition an error message in red is shown
Ho can I do that ? If I should use Ismatch() where I have to put it. thanks
It sounds to me like you could use Ismatch here just fine.
There are probably numerous ways that you could implement this - but here's one to try out:
Walking through the IF statement -- If the user inputs a code that matches your pattern -- AcceptCode is set to 1 and the form is submitted. If a user inputs a code that does NOT match your pattern -- AcceptCode is set to 0 and the form is NOT submitted.
The next step -- you can use the variable "AcceptCode" to change the formatting for boxes and visibility for text. So, for instance...to control the color of the box for a TextInput control, we set the BorderColor parameter to something like...:
Contrast this implementation with the default implementation for forms:
If(IsBlank(Parent.Error), Parent.BorderColor, Color.Red)
However, if the identity cannot perform your required data validation -- Parent.Error is not going to catch this issue. Ideally, we will combine both of these for your case, so you would want to do something like this:
If(IsBlank(Parent.Error) || (AcceptCode = 1), Parent.BorderColor, Color.Red)
Similarly, you can use AcceptCode to set the visibility on a Label that informs the user when they have not entered a correct code.
Does this help you out?
Not yet working :
If I'm right, Power app Online Studio dont accept comma , this is my function :
Form is always submitting even when I enter a digit code that doesn't match the pattern..
PowerApps Online Studio will accept comma.
, and ; do different things. A quick explanation:
, is used to separate parameters in a function.
; is used to separate actions.
There are 2 ways to use an IF statement:
IF(<condition>, <Actions if True>)
IF(<condition>, <Actions if True>, <Actions if False>)
If you want to do more than one action for the TRUE case, then you use ; between each action for that parameter. If you are getting errors, it would not be from using commas -- there must be another problem. From your code below, I see multiple issues...most notably:
Set(AcceptCode;1); and Set(AcceptCode;0);
I'm a little surprised these aren't causing errors. Set is a fucntion: Set(<variable>,<value) <---- it should use a comma.
