I am currently making a WP widget and i am stuck with this. I want to pass a variable from one function to another. The functions are inside the same class.

 class jpen_Custom_Form_Widget extends WP_Widget 

 public function __construct() 
 $widget_options = array(
 'classname' => 'custom_form_widget',
 'description' => 'This is a Custom Form Widget',
 );

 parent::__construct( 'custom_form_widget', 'Custom Form Widget', $widget_options );

 add_action( 'wp_ajax_send_mail', array( $this, 'deliver_mail' ) );
 add_action( 'wp_ajax_nopriv_send_mail', array( $this, 'deliver_mail' ) );

 
 //...
 function deliver_mail() 
 //How to access $instance['email'] value;
 

 public function form( $instance ) 

 $emailReceiver = '';
 if( !empty( $instance['email'] ) ) 
 $emailReceiver = $instance['email'];
 
 //...
 
 

The normal way would be to make the variable into a class-level variable. (In this case it can probably be private). Of course in order for the deliver_mail() function to be able to use it, the form() function must have been executed first.

class jpen_Custom_Form_Widget extends WP_Widget 

 private $emailReceiver;

 function deliver_mail() 
 //How to access $instance['email'] value;
 print_r($this->emailReceiver); //example of using the value
 

 public function form( $instance ) 

 $this->emailReceiver = '';
 if( !empty( $instance['email'] ) ) 
 $this->emailReceiver = $instance['email'];
 
 //...
 

Make a class variable and set it's value to $instance['email'] to share it in another function.

class jpen_Custom_Form_Widget extends WP_Widget 

 // make a class variable
 public $var;

 function deliver_mail() 
 //How to access $instance['email'] value;

 //Use is any where with $this
 var_dump($this->var);
 

 public function form( $instance ) 

 $emailReceiver = '';
 if( !empty( $instance['email'] ) ) 
 $emailReceiver = $instance['email'];
 

 //set class variable value
 $this->var = $instance['email'];
