ValidationServerFunction

Hello

I'm beginner in Object, i found these classes wonderful.

I ve tried to build a form with no problem. But when i want to make a controle with ValidationServerFunction it doesn't work
For exemple i have a form which works and this field

$form_create_user->AddInput(array(
"TYPE"=>"text",
"NAME"=>"alias",
"ID"=>"alias",
"ValidateAsNotEmpty"=>1,
"ValidateMinimumLength"=>8,
"ValidateMinimumLengthErrorMessage"=>"Longueur mini alias =8",
"MAXLENGTH"=>25,
"ValidationErrorMessage"=>"Erreur saisie Alias.",
"LABEL"=>"<u>A</u>lias",
"ACCESSKEY"=>"A",
"VALUE"=>"",
"ValidationServerFunction"=>"CheckUsernameUnique",
"ValidationServerFunctionErrorMessage"=>"erreur alias pas unique"

i've just writen a funtion to see if the program uses it
function CheckUsernameUnique(){
echo 'je passe dans la fonction CheckUsernameUnique';exit();
return false;
}
The program does not uses it

My question how to do for exemple after user has done the alias name in the form to control alias doesnt exist in a database?

Thanks

You should not call the exit function. You need to return 1 if the field is value is valid, or 0 otherwise.

Hello
Yes i understand i don't need to put exit(); it was just to see if the program passed into in the function.
But it seems ithe program doesn't pass into this function
I ll try to understand and i ll look for the problem.

Please
have you an exemple of form about this type of validation?

THANKS

There is not much to this kind of validation. You just need to define a function that returns 1 or 0 depending on whether the value is valid or not.

If the function is not being called, maybe you are not doing something, like your are not calling the Validate function. Maybe the value does not satisfy one of the other validation conditions.

It is hard to tell without seeing your whole script and what you are doing to test it.

Hello
Sorry not to answer quickly
This is my test scripts

Thanks

You are not calling the Validate() function anywhere.
