PHP获取表单里各项值总结
表单提交的方式
1、GET方式
功能:获取get方式提交的数据
格式:$_GET[“formelement”]
2、POST方式
功能:获取post方式提交的数据
格式:$_POST[“formelement”]
3、REQUEST方式
功能:获取任意方式提交的数据
格式:$_REQUEST[“formelement”]
复选框 、列表框(名称采用数组形式如:"select[]",在获取其值的时候直接使用$_POST["select"]即可)下有范例子:
添加页--列表框:
接收页:
# echo $_POST["selt"]
print_r($_POST["selt"]);
?>
复选框:添加页:
接收页:
#echo $_POST["username"];
#echo $_GET["username"];
#echo $_REQUEST["username"]
#echo $username;
//echo $_POST["chkval"];
print_r($_POST["chkval"]);
?>
1.获取文本框内的值:$_POST["text"]
这里可以检查一下魔术开关是否处于开启(默认是开启的),如果不是开启的可以用addslashes($_POST["text"]);对其进行HTML格式化,语句如下:
if(get_magic_quotes_gpc())
{
//开启状态
echo "开启状态
";
echo stripslashes($_POST["text"]);
}
else
{
echo addslashes($_POST["text"]);
}
2.文件的上传:
文件上传代码:
$f=$_FILES['files'];
$dest_dir='uploads';//设定上传目录
$dest=$dest_dir.‘/’.$f[‘name’];//设置文件名
$r=move_uploaded_file($f['tmp_name'],$dest);
#chmod($dest, 0755);//设定上传的文件的属性
move_uploaded_file ($file,$destc)
将上传的文件移动到新位置
upload_file.php
upload.php
#echo $_FILES["fls"];
#print_r($_FILES["fls"]);
//echo $_FILES["fls"]["name"]; www.2cto.com
$f=$_FILES["fls"];//获取文件框内的值
$dest_dir="uploads";//设定上传目录
$dest=$dest_dir."/".date("ymdhji").$f["name"];//设置文件名
move_uploaded_file($f["tmp_name"],$dest);
#move_uploaded_file()
?>
