如果一個表單中有多個同名複選框，在提交到php時卻只有一個值，而並不像asp那樣是一串用逗號分割的值。有一個很簡單的方法來解決：將複選框的name後面加上[]，例如：<input type="checkbox" name="ccc" value="1"> 改為：<input type="checkbox" name="ccc[]" value="1">。這樣php將得到一個叫ccc的陣列。但這種方法有個問題，如果您要在用戶端對複選框是否被選擇、選擇了幾個用javascript來判斷時，javascript會因為複選框的name中含有[]而出錯。您可以在表單中加入一個隱含域，用javascript設定它的值。
<script language="javascript">
function check()
{
var strchoice="";
for(var i=0;i<document.news.choice.length;i )
{
if (document.news.choice[i].checked)
{
strchoice=strchoice document.news.choice[i].value ",";
}
}
if (!document.news.choice.length)
{
if (document.news.choice.checked)
{
strchoice=document.news.choice[i].value; ","
}
}
strchoice=strchoice.substring(0,strchoice.length-1);
document.news.choiceid.value=strchoice;
alert(document.news.choiceall.value);
}
</script>
<html>
...
<form name="news" action="test.php" method="post" onsubmit="check()">
<input type="checkbox" name="choice" value="1">
<input type="checkbox" name="choice" value="2">
<input type="checkbox" name="choice" value="3">
<input type="checkbox" name="choice" value="4">
<input type="hidden" name="choiceid" value="">
</form>
...
</html>
