Create a new public controller to place the instantiation Code of the CAPTCHA (no new controller is OK, any public controller can).

Example: PublicController.class.php

142536475869710811912Ten13 One14 A15 -16 -17 the18 -<?PHP - namespace Home\controller; -      UseThink\controller; +     classPubliccontrollerextendscontroller{ -          Public functionindex () { +             $this-display (); A         } at          Public functioncode () { -             $config=Array(     -' FontSize ' = 30,//captcha Font Size -' Length ' = 3,//Verify number of code bits -' Usenoise ' =true,//turn off the captcha clutter. -             ); in             $verify=New\think\verify ($config); -             $verify-entry (); to         } +     } -?>

And then the page template inside the need to insert a verification code place to insert code (referring to the above instantiation of the model function, the onclick attribute is to click on the image to change a verification code):
