URL with parameters

[mierlp]

hi

 

For my applications the user needs to create a account. When the account is created

he receives a mail with a unique generated code like : -194539324982423641254025935501407370742

 

Now the user has to login and when it's the first time he has to paste the code

into a edit field to test if it's the right code.

 

But...like the most forums i would like to have a url with this code and when the

user clicks the link in his mail the account must be set to active.

 

How can this be done and how/where to check if this code belong to

the right user

 

Regards Peter

Hi,

if the url has the format www.mywebsite.com/?code=194539324982423641254025935501407370742

you can check the value in your code with

 

myvariable:=UniApplication.Parameters.Values['code'];

 

hope this helps

Hi Peter,

 

 

Below I show the procedures that I use in my project, where for example

I sent an email to activate your user account on the site.

 

1: I saved a key (TGUID) to identify the user token in the Users table in a field called Token.

 

2: We send the activation email account to the User, the body of the email I add the reference to the link as below:

 

To activate your account click on the link: '<a href="http://myapp.com/?et=AU&t=' + sToken +'">' +

'http://myapp.com/?et=AU&t=' + sToken + '</a>';

 

Where the parameter et = AU reports that the type of email is User Activation, the parameter t contains the Token(through sToken variable) of the User that was saved in the database.

 

When the User clicks on the link will load the application and in the OnShow(MainForm) event I do check if there are parameters to be validated:

 

TfmHome.UniFormShow procedure (Sender: TObject);

begin

   if (UniApplication.Parameters.Values ​​['t'] = 'AU') then / /Checks if the parameter t (emailtype) exists and is for user activation(AU).

   begin

     //Validates Token (checks whether the content parameter t)

     if (UniApplication.Parameters.Values ​​['t'] <>'') then

     begin

       //Now with the GetTokenInfo function below, I check if the value of the parameter t is valid. The GetTokenInfo receives the token sent and validates the information in the database.

       if dmSessionModule.SystemObj.GetTokenInfo (UniApplication.Parameters.Values ​​['t']) = True then

       begin

           //Here I show the screen to the User confirm your user and password to activate the user.

           ...

           ... 

       end;

     end;

  end;

end;
