4.13. OwsRequestObj Class

Next: PointObj Class Previous: OutputFormatObj Class  

• Constant names and class member variable names are case-sensitive in PHP.
• Several MapScript functions (all those that access files in the back end such as ms_newMapObj(), drawMap(), etc.) will affect the value of the current working directory (CWD) in the PHP environment. This will be fixed eventually but in the meantime you should be careful about these side-effects.

Constructor:
      
     request = ms_newOwsrequestObj();

     Create a new ows request object.

Members:
     int numparams  
        Number of parameters in the request object. Read only.

Methods:

     int loadparams()
        Initializes the OWSRequest object from the cgi environment variables
        REQUEST_METHOD, QUERY_STRING and HTTP_COOKIE.  Returns the number of 
        name/value pairs collected.

     int setparameter(string name, string value)
        Set a request parameter.  For example :
          $request->setparameter('REQUEST', 'GetMap');

     string getname(int index)
       Return the name of the parameter at *index* in the request's array
       of parameter names.

     string getvalue(int index)
        Return the value of the parameter at *index* in the request's array
        of parameter values.
