存儲值

Question

我用這個This to make add/remove select list

<form action="home.php?action=test" method="post" id="myform" name="myform" onsubmit="ValidatePageForm()"> 
<fieldset> 
<select name="selectfrom" id="select-from" multiple size="5"> 
<option value="1">Item 1</option> 
<option value="2">Item 2</option> 
<option value="3">Item 3</option> 
<option value="4">Item 4</option> 
</select> 
<a href="JavaScript:void(0);" id="btn-add">Add &raquo;</a> 
<a href="JavaScript:void(0);" id="btn-remove">&laquo; Remove</a> 
<select name="selectto" id="select-to" multiple size="5"> 
<option value="5">Item 5</option> 
<option value="6">Item 6</option> 
<option value="7">Item 7</option> 
</select> 
</fieldset> 
<input name="submit" type="submit" value="submit" /> 
</form> 

使用下面的腳本中，我可以看到所選選項

<script type="text/javascript"> 
function ValidatePageForm() 
{ 
$('#select-to option').each(function(){ 
alert($(this).val()); 
}); 
} 
</script> 

但是值我怎樣才能把這些值，並將其儲存在數據庫中?? ，因爲當我提交我沒有看到數據後轉儲。

有關這方面的任何幫助。

感謝， 沙赫扎德

<form action="home.php?action=test" method="post" id="myform" name="myform" onsubmit="ValidatePageForm()"> 
<fieldset> 
<select name="selectfrom" id="select-from" multiple size="5"> 
<option value="1">Item 1</option> 
<option value="2">Item 2</option> 
<option value="3">Item 3</option> 
<option value="4">Item 4</option> 
</select> 
<a href="JavaScript:void(0);" id="btn-add">Add &raquo;</a> 
<a href="JavaScript:void(0);" id="btn-remove">&laquo; Remove</a> 
<select name="selectto[]" id="select-to" multiple size="5"><!--declare name as array--> 
<option value="5">Item 5</option> 
<option value="6">Item 6</option> 
<option value="7">Item 7</option> 
</select> 
</fieldset> 
<input name="submit" type="submit" value="submit" /> 
</form> 

既然你試圖讓多個值，首先需要聲明的數組的元素，然後就可以在PHP中獲取這些值這樣

<?php 
    if(isset($_POST['selectto'])){ 
     $selecto = $_POST['selectto']; 
     foreach($selecto as $selecto_vals) 
      echo $selecto_vals;   
    } 
    ?>
