Bear akılda, bir ebeveyn formu veya bir şey yapmayacağım bir js dinleyici olmadan girişini gönderin. Yani en basit yolu, örneğin, aksiyon sayfanızın adı olarak sahip bir <form> yapmak olacaktır:

<form action="<?echo $PAGE_NAME?>" method="POST" > 
    <table class="table" align="center"> 
    <tr> 
     <thead> 
      <td>year</td> 
      <td>Area at the starting year</td> 
      <td>Maximum profit per hectare</td> 
      <td>Minimum profit per hectare</td> 
      <td>Area at the ending year</td> 
      <td>Area in hectare</td> 
      <td></td> 
     </thead> 
    </tr> 

    <tr> 
     <td>2011-2012</td> 
     <td><input type="number" id="areas12" name="areas12"></td>

     <td><input type="number" id="areae12" name="areae12"></td> 
     <td><input type="number" id="volume12" name="volume12"></td> 
     <td> 
      <button type="submit" class="btn btn-primary btn btn-block">Save</button> 
      <input type="hidden" name="submitted1" value="1">
