  Validation

  Apr 24, 2012 02:59 AM|LINK

  Hi one more time!

  I´m really stuck at a validation that I need to do. If anyone could help me I would appreciate.

  I have a form where I put a text field to the user insert a page addreess. I inserted two validations. One for when the field is empty and the other to check if the link already exists in the database. So far, so good. The problem is...

  When the user insert a the page address I can´t have the "http://" recorded in my db. So I have to validade the field in order to never have it recorded.

  One other option that I was thinkings is to accept it in the form but don´t record in the db, disconsidering this part from the address.

   

  thanks a lot!

  Thanks a lot.

  Actually I don´t know how to make this validation.

  I can´t have the "http" recorded in my database but I don´t know how to write de code to prevent the user from posting it.

   if (link = ( contains "http")) {

               linkErrorMessage = "You must specify an email address.";            

  isValid = false;         } 

   

  Thanks a lot

   if (link = ( contains "http")) {

  Almost:

  var link = Request["link"];
  if(link.Contains("http")){
      //failed

  Although you might be better off with:

  if(link.StartsWith("http")){
      //failed

  
  Or you might even accept it and then take care of stripping the http off: 

      var link = "";
      if(IsPost && !Request["link"].IsEmpty()){
          link = Request["link"].Replace("http://", "");
      }
