PHP從表單選擇生活中獲取變量

Question

我需要從生活中的表單選擇選項變量，因爲它在相同形式的下一個字段中使用。任何線索如何做到這一點？我想這可以用JavaScript來完成，但我不知道如何使用JavaScript。提前致謝。 這裏是形式的代碼：

echo ' <form action="dodaj_harmonogram.php" method="post">'; 

echo ' <div class="control-group"> 
    <label class="control-label">Nazwa harmonogramu:</label> 
    <div class="controls"> 
     <input type="text" name="nazwa_harmonogramu" required /> 
     <p class="help-block"></p> 
    </div> 
    </div>'; 
echo 'Profil:<br /> 
          <select name="profil"> 
           '; pobierz_profile(); 
           echo'</select><br>'; 
echo 'Playlista:<br /> 
<select name="playlista" id="lista"> 
'; pobierz_playlisty($id_playlisty); 
echo'</select><br>'; 
$czas_playlisty = zaokraglanieczasu(pobierz_czas_utworow_playlisty($id_playlisty)); 
$czas_sekundy = ceil($czas_playlisty); 
echo ' <div class="control-group"> 
    <label class="control-label">Odstęp (min):</label> 
    <div class="controls"> 
     <input type="number" min="'.$czas_sekundy.'" name="odstep" required /> 
     <p class="help-block"></p> 
    </div> 
    </div>'; 
echo ' <div class="control-group"> 
    <label class="control-label">Data od</label> 
    <div class="controls"> 
     <input type="date" name="data_od" required /> 
     <p class="help-block"></p> 
    </div> 
    </div>'; 
echo ' <div class="control-group"> 
    <label class="control-label">Data do</label> 
    <div class="controls"> 
     <input type="date" name="data_do" required /> 
     <p class="help-block"></p> 
    </div> 
    </div>'; 
echo ' Dni:<br />' ;

包括jQuery的

<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script> 

<script> 
// Then use an event handler to check when the select changes 
$('select').on('change', function() 
{ 
    // Show an alert 
    alert("The new value of the select is " + $(this).val()); 
    // You should place your logic here to do what you want with that value 
    // E.g. change the page 
    document.location.href = $(this).val(); 
}); 
</script>
