从Wordpress函数访问PHP对象

Question

I'm currently having some issues trying to incorporate 2 Class Libraries (1. Form Builder & 2. Custom Emailer) into a Wordpress plugin.

Background:

1. Form Builder (based of a modified version of PFBC http://www.imavex.com/pfbc3.x-php5/index.php) - Using to Generate Forms for Rapid Web Development.

2. Custom Emailer - In-house library that provides an API to another system we've developed.

The complexity seems to be outputting the javascript in the footer for page speed optimisation, using wordpress hooks to output in the footer.

My question is, how do layout my code so I can access Classes from other functions.

eg. echo $email->formid();

function wpplugin_blah_forms_init_form()
{
    $email = new DealerSolutionsEmailGateway(); 
    $email->formid = 'blah'; // ID of the <form>
}

function wpplugin_blah_forms_show($atts)
{
    // Get Shortcode parameter "form"
    $forms = shortcode_atts( array('form' => '', 'view' => 'SideBySide'), $atts );

    // Init EmailProcessor
    wpplugin_blah_forms_init_form();

    echo $email->formid();

    $form = new Form("General");
    //$form->configure($form_config);

    $form->addElement(new Element\HTML($theme));
    $form->addElement(new Element\HTML('<h2>General Enquiry</h2>'));
    $form->addElement(new Element\Hidden("form", "General"));
    $form->addElement(new Element\HTML('<legend>Personal Details</legend>'));
    $form->addElement(new Element\Button("Submit My Enquiry"));
    return $form->render(); // display form
}
add_shortcode('show_form', 'wpplugin_blah_forms_show');

The above example is a cut down version of what im doing, im just not sure how to access $email when it was initiated in another function.

Answer 1

for firstclass.php

<?php

    class Firstclass{
        function __construct(){

        }
        function init(){

        }
        function temp1(){

        }

    }

    if(class_exists('Firstclass'))
        $firstclass_object = new Firstclass();
?>

In secondclass.php, you can access functions of firstclass.php as

<?php
    class Firstclass{
        function __construct(){

        }
        function temp2(){
            global $firstclass_object;
            $firstclass_object-> temp1;       
        }    
    }
?>

Here for your answer, you can do that as below

//for accessing form id declare it as a global variable
global $email;    
echo $email->formid;
