我正在尝试创建我的第一个 Magento 扩展程序,但我已经陷入了第一步。
添加{{block type="rick_printer/print" text="Hello world"}}
到 CMS 页面或块时,我希望显示“Hello world”。不幸的是,什么也没有发生。这是我的代码:
app\code\local\Rick\Printer\etc\config.xml
<?xml version="1.0" encoding="UTF-8"?>
<config>
<modules>
<Rick_Printer>
<version>0.0.1</version>
</Rick_Printer>
</modules>
<global>
<blocks>
<rick_printer>
<class>Rick_Printer_Block_Print</class>
</rick_printer>
</blocks>
</global>
</config>
app\etc\modules\Rick_Printer.xml
<?xml version="1.0" encoding="UTF-8"?>
<config>
<modules>
<Rick_Printer>
<active>true</active>
<codePool>local</codePool>
</Rick_Printer>
</modules>
</config>
app\code\local\Rick\Printer\Block\Print.php
class Rick_Printer_Block_Print extends Mage_Core_Block_Abstract
{
protected function _construct()
{
$this->setTemplate('rick/printer/view.phtml');
parent::_construct();
}
public function printIt()
{
$text = $this->getText();
if (!$text) {
$msg = "Please provide a text!";
echo $msg;
return array();
}
return $text;
}
}
app\design\frontend\default\default\template\rick\printer\print.phtml
<?php
$text = $this->spinIt();
echo $text;
?>
我知道代码很丑陋,我可能做错了。非常感谢任何帮助!
谢谢
更新:从 Vinai 的回答中应用修复后,我的app\code\local\Rick\Printer\etc\config.xml现在看起来像这样:
<?xml version="1.0" encoding="UTF-8"?>
<config>
<modules>
<Rick_Printer>
<version>0.0.1</version>
</Rick_Printer>
</modules>
<global>
<blocks>
<rick_printer>
<class>Rick_Printer_Block</class>
</rick_printer>
</blocks>
</global>
</config>
并且在访问 CMS 页面(未显示)时收到以下错误消息:
class Rick_Printer_Block_Print extends Mage_Core_Block_Abstract
{
protected function _construct()
{
$this->setTemplate('rick/printer/view.phtml');
parent::_construct();
}
public function printIt()
{
$text = $this->getText();
if (!$text) {
$msg = "Please provide a text!";
echo $msg; return array();
}
return $text;
}
}
