Adding Custom Bricks

Hey Guys,
I'm trying to add custom bricks based on the Field Bricks. When I add the following code to the bricks.php file, it works perfectly. Code:
<code>
class Am_Form_Brick_Accounts extends Am_Form_Brick
{
protected $field = null;
static function createAvailableBricks($className)
{
$res = array();
foreach(Am_Di::getInstance()->userTable->customFields()->getAll() as $field)
{
if (strpos($field->name, 'aff_') === 0) continue;
if (!is_numeric(strpos($field->name, 'account')) || strpos($field->name, 'account') != 0) continue;
$res[] = new self('my-'.$field->getName());
}
return $res;
}
public function __construct($id = null, $config = null)
{
$numAccounts = Am_Di::getInstance()->user->maxaccounts;
parent::__construct($id, $config);
$fieldName = str_replace('my-', '', $id);
$this->field = Am_Di::getInstance()->userTable->customFields()->get($fieldName);
$accountNum = str_replace('account','',$fieldName);
$accountNo = intval($accountNum);
// to make it fault-tolerant when customfield is deleted
if (!$this->field && $accountNo <= $numAccounts)
$this->field = new Am_CustomFieldText($fieldName, $fieldName);
}
function getName()
{
return $this->field->title;
}
function insertBrick(HTML_QuickForm2_Container $form)
{
$numAccounts = Am_Di::getInstance()->user->maxaccounts;
$accountNum = str_replace('account','',$this->field->name);
$accountNo = intval($accountNum);
if ($accountNo <= $numAccounts) {
$this->field->addToQF2($form);
$elementarray = $form->getElementsByName($this->field->name);
$element = $elementarray[0];
if($this->getConfig('isDisabled'))
{
$element->toggleFrozen(true);
}
}
}
function getFieldName() { return $this->field->name; }
public function initConfigForm(Am_Form $form)
{
$element =& $form->addAdvCheckbox("isDisabled")->setLabel("Is Disabled?");

}
}
</code>

However, of course this will be overwritten on upgrade. So what I'm trying to do is create a plugin to do it. I have the plugin file MyBricks.php being:
<code>
<?php
class Am_Plugin_MyBricks extends Am_Plugin
{
const PLUGIN_STATUS = self::STATUS_PRODUCTION;
const PLUGIN_REVISION = '1.0.0';

protected $id;
protected $done = false;
public function __construct(Am_Di $di, array $config)
{
$this->id = $di->config->get('myBricks');
// print_rre($this->id);
parent::__construct($di, $config);
}
function onLoadBricks()
{
require_once dirname(__FILE__) . '/AccountsBrick.php';

}
}
</code>
and then the AccountsBrick.php file holds the Am_Form_Brick_Accounts class. However, when I do this, the bricks show up in the profile form editing, but when I try to view the profile after adding some of these bricks, I get the "An Error has Occurred" page. Any ideas?

Thanks,
Paul

The error was:
Error in Am_Form_Brick::createFromRecord cannot create class [Am_Form_Brick_Accounts] - not defined

with expanded information being:

Doing this doesn't seem to work. The bricks don't appear in the profile forms editor.

Attached is my configs folder.

Alex,
Should there be a closing ?> at the end of the file? I tried it both with and without and while it seems to work, when I save the changes to the profile page, it does save the changes, however, it then throws me to a blank page -- no error message, completely blank. When I look at the log, it shows an error:

You must be authorized to access this area

and yet I am logged in as admin. The expanded info is:

OK, now the site code looks like this:

PHP:

  <?php

        class Am_Form_Brick_Accounts extends Am_Form_Brick
        {
            protected $field = null;
            static function createAvailableBricks($className)
            {
                $res = array();
                foreach(Am_Di::getInstance()->userTable->customFields()->getAll() as $field)
                {
                    if (strpos($field->name, 'aff_') === 0) continue;
                    if (!is_numeric(strpos($field->name, 'account')) || strpos($field->name, 'account') != 0) continue;
                    $res[] = new self('my-'.$field->getName());
                }
                return $res;
            }
            public function __construct($id = null, $config = null)
            {
                parent::__construct($id, $config);
                $fieldName =  str_replace('my-', '', $id);
                $this->field = Am_Di::getInstance()->userTable->customFields()->get($fieldName);
                // to make it fault-tolerant when customfield is deleted
                if (!$this->field)
                    $this->field = new Am_CustomFieldText($fieldName, $fieldName);
            }
            function getName()
            {
                return $this->field->title;
            }
            function insertBrick(HTML_QuickForm2_Container $form)
            {
                $numAccounts = Am_Di::getInstance()->user->maxaccounts;
                $accountNum = str_replace('account','',$this->field->name);
                $accountNo = intval($accountNum);
                if ($accountNo <= $numAccounts) {
                    $this->field->addToQF2($form);
                    $elementarray = $form->getElementsByName($this->field->name);
                    $element = $elementarray[0];
                    if($this->getConfig('isDisabled'))
                    {
                        $element->toggleFrozen(true);
                    }
                }
            }
            function getFieldName() { return $this->field->name; }
            public function initConfigForm(Am_Form $form)
            {
                $element =& $form->addAdvCheckbox("isDisabled")->setLabel("Is Disabled?");

            }
        }
 


However, when I go to the profile forms editor and click save, it still throws me to a blank page. There's no error in the logs, just throws me to a blank page. Curious...

For those of you interested, alex found the problem. It was a tab character before the <?php in the site.php file.

I created a custom brick and included it in site.php. it worked but it causes the newsletter brick to disappear. The one I created below is just a copy of the HTML text brick with a placeholder added so I can create bricks to automatically place pre-determined HTML in sign up forms. Anybody have this issue or know why it causes the newsletter brick to disappear in the form editor?

PHP:

class Am_Form_Brick_MyCustomText extends Am_Form_Brick
{
    static $counter = 0;
    public function __construct($id = null, $config = null)
    {
        $this->name = ___('Custom text');
        parent::__construct($id, $config);
    }
    public function initConfigForm(Am_Form $form)
    {
        $form->addTextarea('html', array('rows' => 15, 'class' => 'el-wide', 'placeholder' => '<p><b>My Custom Text</b></p>'))
            ->setLabel(___('HTML Code that will be displayed'));
        $form->addText('label', array('class' => 'el-wide'))->setLabel(___('Label'));
        $form->addAdvCheckbox('no_label')->setLabel(___('Remove Label'));
    }

    public function insertBrick(HTML_QuickForm2_Container $form)
    {
        $attrs = $data = array();
        $data['content'] = $this->getConfig('html');
        if ($this->getConfig('no_label')) {
            $attrs['class'] = 'no-label';
        } else {
            $data['label'] = $this->getConfig('label');
        }
        $form->addStatic('html' . (++self::$counter), $attrs, $data);
    }
    public function isMultiple()
    {
        return true;
    }
}
