get php value Function Summarize submit data Way Format of Obtain form

 

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:

 

 

 

1212 

   

   

   

  2121

 

   

   

   

  11212

 

   

   

   

 

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()

?>
