如何在Toad中使用PL/SQL提交HTML表單？

Question

我想提交數據從一個使用PL/SQL在蟾蜍與Web工具包。我有以下

procedure add_car is 
     begin 
      htp.title('August Vehicle Directory'); 
      htp.bodyopen; 
      Htp.tableopen('border=1 align=center'); 
        --Header: 
        HTP.tablerowopen; 
         htp.tabledata(style('Add New Vehicle','#t_1'),'center', ccolspan => '5'); 
        HTP.tablerowclose; 
        htp.tablerowopen; 
         htp.tabledata(style('Please add a vehicle to the database by filling out the forum below.','#t_msg'),'center',ccolspan=>'11'); 
        htp.tablerowclose; 

        -- Text-box entry: 
        htp.tablerowopen; 
         HTP.P('<td>'); 
          htp.tableopen(); 
          -- 
           htp.formopen('john_package.submit_newcar','post'); 
            htp.tablerowopen; 
            htp.tabledata(style('Make: ','#t_b'),'center'); 
            htp.tabledata('<input type="text" name="make_box" size="20" maxlength="30" value="">'); 
            htp.tabledata('&nbsp'); 
            htp.tabledata(style('Model: ','#t_b'),'center'); 
            htp.tabledata('<input type="text" name="model_box" size="20" maxlength="30" value="">'); 
            htp.tabledata('&nbsp'); 
            htp.tabledata(style('Year: ','#t_b'),'center'); 
            htp.tabledata('<input type="text" name="year_box" size="20" maxlength="30" value="">'); 
            htp.tabledata('&nbsp'); 
            htp.tabledata(style('Engine: ','#t_b'),'center'); 
            htp.tabledata('<input type="text" name="engine_box" size="20" maxlength="30" value="">'); 
            htp.tabledata('&nbsp'); 
            htp.tabledata(style('Seats: ','#t_b'),'center'); 
            HTP.P('<td>'); 
             htp.formSelectOpen('seats_dropdown'); 
             htp.formSelectOption('1'); 
             htp.formSelectOption('2'); 
             htp.formSelectOption('3'); 
             htp.formSelectOption('4'); 
             htp.formSelectOption('5'); 
             htp.formSelectOption('6'); 
             htp.formSelectOption('7'); 
             htp.formSelectOption('8'); 
             htp.formSelectOption('9'); 
             htp.formSelectOption('10'); 
             htp.formSelectClose; 
            HTP.P('</TD>'); 
            htp.tablerowclose; 
           htp.formclose; 
           -- 
          htp.tableclose; 
         HTP.P('</TD>'); 
        htp.tablerowclose; 

        HTP.tablerowopen; 
         HTP.P('<td align =center colspan=2>'); 
         htp.tableopen(); 
           htp.tabledata(support.button(0,'p_Submit','Add Vehicle','onClick="return this.form"')); 
           htp.tabledata(support.button(0,'john_package.loadpage','Cancel', 1, null, null),'center'); 
           htp.tableclose; 
         HTP.P('</TD>');    
        HTP.tablerowclose; 

      htp.tableclose; 
      htp.bodyclose; 
     exception 
      when others then 
       htp.p('Error: '||TO_CHAR(SQLCODE)||'-'||SQLERRM); 
       write_log ('john_package.add_car', to_char(SQLCODE)||'-'||SQLERRM); 
     end add_car; 

然後我有shuold從上面所提交的表單中插入數據的過程：

 procedure submit_newcar(
      p_make  varchar2 default null, 
      p_model  varchar2 default null, 
      p_year varchar2 default null, --Year produced 
      p_engine  varchar2 default null, --Engine type 
      p_seats  varchar2 default null --Number of seats 
      ) IS 
     begin 
      INSERT INTO JOHN_TABLE_CAR 
      (ID, MAKE, MODEL, YEAR, ENGINE, SEATS) 
      VALUES 
      (null, p_make, p_model, p_year, p_engine, p_seats); 
     exception 
      when others then 
       htp.p('Error: '||TO_CHAR(SQLCODE)||'-'||SQLERRM); 
       write_log ('john_package.submit_newcar', to_char(SQLCODE)||'-'||SQLERRM); 
     end submit_newcar; 

這似乎並不奏效，我希望的方式。每次點擊我的「添加車輛」按鈕，似乎我的「submit_newcar」過程插入沒有被調用。我怎樣才能使這個工作正常？

Answer 1

所以這個問題的答案非常簡單，並且被發現整個檢查頁面的源代碼HTML。基本上，我沒有在表單中包含我的「提交」，因此每次點擊提交按鈕都不會做任何事情。

爲了解決我需要靠攏

   HTP.P('<td align =center colspan=2>'); 
        htp.tableopen(); 
          htp.tabledata(support.button(0,'p_Submit','Add Vehicle','onClick="return this.form"')); 
          htp.tabledata(support.button(0,'john_package.loadpage','Cancel', 1, null, null),'center'); 
        htp.tableclose; 
       HTP.P('</TD>'); 
-- /\ submit button is inside form close now! 
htp.formclose; 

這樣做解決了我的問題表單內的以下問題。
