通常来说,php中总是只获取最后一个复选框的值,那么如何才能获取所有复选框的值?

解决办法如下:

form表单的部分代码如下:

<input type="checkbox" name="frm_tag[]" value="1">1
<input type="checkbox" name="frm_tag[]" value="2">2
<input type="checkbox" name="frm_tag[]" value="3">3
<input type="checkbox" name="frm_tag[]" value="4">4
<input type="checkbox" name="frm_tag[]" value="5">5

Copy after login

php处理POST传递过来数据的代码如下:

$str_tag = "";
$frm_tag = $_POST['frm_tag'];
for($i=0;$i<count($frm_tag);$i++){
  echo $frm_tag[$i]."<br>";
  if($i==0)
   $str_tag = $frm_tag[$i];
  else
   $str_tag = $str_tag.",".$frm_tag[$i];
}
echo $str_tag;
}

Copy after login

相信本文所述对大家深入掌握PHP程序设计有一定的借鉴价值。
