PHP中获取CHECKBOX提交的内容及checkbox全选

提交页?

//js控制全选/取消全选? 

<script type="</code"><code class="php string">"text/javascript"</script>>?

function check_all(obj,cName)?

{?

????var checkboxs = document.getElementsByName(cName);?

????for(var

i=0;i<checkboxs.length obj.checked>
</checkboxs.length>

}?

??

<form id="</code">
<code class="php string"><span style="color: #0000ff;">"form1"</span>

name="form1" method="post" action="receive.php">?

<table width="</code">
<code class="php string"><span style="color: #0000ff;">"100%"</span>

>

???????

<td colspan="</code">
<code class="php string"><span style="color: #0000ff;">"2"</span>

>?

<div align="</code">
<code class="php string"><span style="color: #0000ff;">"center"</span>

>?

<input type="</code"><code class="php string">"checkbox" name="all" onclick="check_all(this,'checkbox[]')" />全选/全不选

???????????<input type="</code"><code class="php string">"checkbox" name="checkbox[]" value="item1" />?

???????????1?

???????????2?

???????????3?

????????????

???????<td></td>

?????

???????

<td colspan="</code">
<code class="php string"><span style="color: #0000ff;">"2"</span>

>?

??

<div align="</code">
<code class="php string"><span style="color: #0000ff;">"center"</span>

>?

???????????<input type="</code"><code class="php string">"submit" name="Submit" value="提交" />?

???????????

???????<td></td>

如果名字不用数组的话，php只能获取到最后一个checkbox的值?

??

receive.php?

$checkbox = $_POST['checkbox'];?

??

<span style="color: #008200;">/*如果要获取第一个数值就直接中止输出，使用下面代码，相当于radiobox了>.</span>

for($i=0;$i<code class="php functions">count($checkbox);$i++)?

{?

if(!is_null($checkbox[$i]))?

{$chechvalue=$checkbox[$i];break;}?

}?

echo $chechvalue;?

??

/*如果要获取全部数值则使用下面代码*/?

{?

if(!is_null($checkbox[$i]))?

{$chechvalue.=$checkbox[$i]}?

}?

echo $chechvalue;
