Simple Jwt Login [simple-jwt-login:request] Shortcode

The Simple-JWT-Login shortcode is designed to retrieve a specific request parameter. It works by checking if a ‘key’ parameter is set. If not, it returns an empty string. If the ‘key’ parameter is set, it checks if this parameter exists in the global $_REQUEST array. If it does, it returns the sanitized value of the parameter, otherwise, it returns an empty string.

Shortcode: [simple-jwt-login:request]

Parameters

Here is a list of all possible simple-jwt-login:request shortcode parameters and attributes:

• key – key-name of the requested data in the $_REQUEST array

Examples and Usage

Basic example – A simple usage of the shortcode to retrieve a request parameter by key.

[simple-jwt-login:request key="username" /]

This shortcode will return the value of the ‘username’ parameter from the request if it exists. If the ‘username’ parameter is not present in the request, the shortcode will return an empty string.

Advanced examples

Using the shortcode to retrieve multiple request parameters by their keys.

[simple-jwt-login:request key="username" /]
[simple-jwt-login:request key="password" /]

In this example, the shortcode is used twice to retrieve the ‘username’ and ‘password’ parameters from the request. Each shortcode will return the value of its respective parameter if it exists. If a parameter is not present in the request, the corresponding shortcode will return an empty string.

It’s important to note that the ‘key’ attribute in the shortcode corresponds to the key of the request parameter you want to retrieve. Therefore, you should replace ‘username’ or ‘password’ with the actual key of the parameter you are interested in.
