Oninput processing Code help for four variables

Question

Hi,
I am  new to BSP. I am trying to write the code for this requirement but always getting error.
In the layout , I have four input boxes  say input1,input2,input3,input4.
User can enter anyone or all or some  of them and click OK.
so oninputprocessing, I want to check if any one of this is not empty then a select statement on a table should execute.
if the select statement fetches records then it should go to next page.Otherwise it should through exception.
thank you.

Hi,
First define the input fields in layout and in oninputprocessing validate the fields and with the help of flags we can display the messages in same page.
For displaying messages in detail  [Validation|https://wiki.sdn.sap.com/wiki/x/CIHvB ]
Here is the sample code in oninputprocessing :
Case w_eventid.
when '<button-name>'.
call method cl_htmlb_manager=>get_data
      exporting
        request       = runtime->server->request
        name
        ='inputfield'
        id            = '<idname>'
      receiving
        data          = w_object.
    w_inputfield ?= w_object.
    w_in_value = w_inputfield->value.
    w_prid = w_in_value.
    clear: w_object,w_in_field,w_in_value.
if w_input1 is initial.
fl_flag = 1.
endif.
    call method cl_htmlb_manager=>get_data
      exporting
        request       = runtime->server->request
        name
        ='inputfield'
        id            = '<idname>'
      receiving
        data          = w_object.
    w_inputfield ?= w_object.
    w_in_value = w_inputfield->value.
    w_prname = w_in_value.
    clear: w_object,w_in_field,w_in_value.
if w_input2 is initial.
fl_flag = 2.
endif.
    call method cl_htmlb_manager=>get_data
      exporting
        request       = runtime->server->request
        name
        ='inputfield'
        id            = 'clntname'
      receiving
        data          = w_object.
    w_inputfield ?= w_object.
    w_in_value = w_inputfield->value.
    w_clntname = w_in_value.
    clear: w_object,w_in_field,w_in_value.
    if w_input3 is initial.
    fl_flag = 3.
    endif.
    call method cl_htmlb_manager=>get_data
      exporting
        request       = runtime->server->request
        name
        ='inputfield'
        id            = '<idname>'
      receiving
        data          = w_object.
    w_inputfield ?= w_object.
    w_in_value = w_inputfield->value.
    w_person = w_in_value.
    clear: w_object,w_in_field,w_in_value.
  if w_input4 is initial.
    fl_flag = 4.
    endif.
<Select statement>
Endcase.
For flags write the following code in layout tab:
<%
  if fl_flag eq 1.
          %>
          <center>
          <br><font  style="font-size:11px" face="Verdana" color ="#FF0000">"All Fields are Mandatory"</b></center>
          <% endif.%>
Hope this solves the issue.
