thinkphp5 request, variable

request:

1. Request information

If you want to get the current request information, you can use the \ think \ Request class.

$request = Request::instance();

You can also use helper functions

$request = request();

You can get through this class: get URL information; set / get module / controller / operation name; get request parameters; get routing and scheduling information; set request information.

Input variable

You can complete the detection, acquisition and security filtering of global input variables through the Request object, including support for $ _GET, $ _POST, $ _REQUEST, $ _SERVER, $ _SESSION, $ _COOKIE, $ _ENV and other system variables, and file upload information.

1. You can use the has method to detect whether a variable parameter is set

Request::instance()->has('id','get');
Request::instance()->has('name','post');

Or use helper functions

input('?get.id');
input('?post.name');

1. Variable acquisition

Variable acquisition uses the following methods and parameters of the \ think \ Request class:

Variable type methods ('variable name / variable modifier', 'default value', 'filter method')

 

// Get the name variable of the current request 
Request :: instance ()-> param ( ' name ' ); // Get all the variables of the current request (filtered) 
Request :: instance ()-> param (); // Get All variables of the current request (original data) 
Request :: instance ()-> param ( false ); // Get all variables of the current request (including the uploaded file) 
Request :: instance ()-> param ( true );

 

Use helper functions to achieve:

input('param.name');
input('param.');
or
input('name');
input('');

Get GET variable

Request :: instance ()-> get ( ' id ' ); // Get a get variable 
Request :: instance ()-> get ( ' name ' ); // Get get variable 
Request :: instance ()-> get (); // Get all get variables (filtered array) 
Request :: instance ()-> get ( false ); // Get all get variables (original array)

Use the built-in helper function input method to achieve the same function:

input('get.id');
input('get.name');
input('get.');

Get POST variable

Request :: instance ()-> post ( ' name ' ); // Get a post variable 
Request :: instance ()-> post (); // Get all filtered post variables 
Request :: instance ()- > post ( false ); // Get all post original variables

Use helper functions to achieve:

input('post.name');
input('post.');
