These INPUT TYPE names are called LangType, if you take these values with Request.GetParameter ("LangType"), which one is to take? So at this time, you can't use GetParameter to take information, and you should use getParameterValues to take information. Use this method to retrieve the input type of the front end in an array, so you can declare a string array to undertake, usage as follows :
String langtype [] = Request.getParameterValues ("langtype");
// Use getParameterValues method to take the verified value within the langType [] array
if (LangType! = NULL)
// front end user, if you have not hook
//Request.getParameterValues ("LangType ") will receive NULL values
{
Int size = java.lang.reflect.Array.getLength (LangType);
/ / Get this array size
For (int i = 0; i { Out.println (langtype [i] ""); } // Take the array data using a FOR back ring }
Out.println (langtype [i] "");
}
// Take the array data using a FOR back ring
