In php, the form uses both POST and GET to pass parameter descriptions.

1. I used it before. When submitting form post, the url of the action passes the get parameter, which can be obtained by the server:

The code is as follows: Copy code

<? Php
Print_r ($ _ GET );
Print_r ($ _ POST );
?>
 
<Form action = "get_post.php? Id = 100 "method =" post ">
Name: <input type = "text" name = "name"/> <br>
Age: <input type = "text" name = "age"/> <br>
<Input type = "submit" value = "submit"/>
</Form>

2. If your form submission type is get, the parameters passed in the url cannot be obtained:

The code is as follows: Copy code

<? Php
/**
* Test get and post submission.
* @ Link (http://www.111cn.net)
*/
Print_r ($ _ GET );
Print_r ($ _ POST );
?>
 
<Form action = "get_post.php? Id = 100 "method =" get ">
Name: <input type = "text" name = "name"/> <br>
Age: <input type = "text" name = "age"/> <br>
<Input type = "submit" value = "submit"/>
</Form>
