Magento创建后台表单处理页_Magento教程

假设这个模块名字为：Mage_Sintax

1. 模块声明

文件: app/etc/modules/Mage_Sintax.xml

			Xml代码  

			<?xml version="1.0"?>  

			<config>  

			    <modules>  

			        <Mage_Sintax>  

			            <active>true</active>  

			            <codePool>local</codePool>  

			        </Mage_Sintax>  

			    </modules>  

			</config>

2. 生成Module配置文件.
文件: app/code/local/Mage/Sintax/etc/config.xml

			Xml代码  

			<?xml version="1.0"?>  

			<config>  

			    <modules>  

			        <Mage_Sintax>  

			            <version>0.1.0</version>  

			        </Mage_Sintax>  

			    </modules>  

			    <global>  

			        <models>  

			            <sintax>  

			                <class>Mage_Sintax_Model</class>  

			                <resourceModel>sintax_mysql4</resourceModel>  

			            </sintax>  

			            <sintax_mysql4>  

			                <class>Mage_Sintax_Model_Mysql4</class>  

			            </sintax_mysql4>  

			        </models>  

			        <blocks>  

			            <sintax>  

			                <class>Mage_Sintax_Block</class>  

			            </sintax>  

			        </blocks>  

			        <helpers>  

			            <sintax>  

			                <class>Mage_Sintax_Helper</class>  

			            </sintax>   

			        </helpers>  

			    </global>  

			    <admin>  

			        <routers>  

			            <sintax>  

			                <use>admin</use>  

			                <args>  

			                    <module>Mage_Sintax</module>  

			                    <frontName>sintax</frontName>  

			                </args>  

			            </sintax>  

			        </routers>  

			    </admin>  

			    <adminhtml>  

			        <translate>  

			            <modules>  

			                <mage_adminhtml>  

			                    <files>  

			                        <sintax>Mage_Sintax.csv</sintax>  

			                    </files>  

			                </mage_adminhtml>  

			            </modules>  

			        </translate>  

			        <menu>  

			            <catalog>  

			                <children>  

			                    <sintax_adminform translate="title" module="sintax">  

			                        <title>My Form</title>  

			                        <action>sintax/adminhtml_myform</action>  

			                    </sintax_adminform>  

			                </children>  

			            </catalog>  

			        </menu>  

			        <acl>  

			            <resources>  

			                <admin>  

			                    <children>  

			                        <catalog>  

			                            <children>  

			                                <sintax_adminform>  

			                                    <title>My Form</title>  

			                                </sintax_adminform>  

			                            </children>  

			                        </catalog>  

			                    </children>  

			                </admin>  

			            </resources>  

			        </acl>  

			        <layout>  

			            <updates>  

			                <sintax>  

			                    <file>sintax.xml</file>  

			                </sintax>  

			            </updates>  

			        </layout>  

			    </adminhtml>  

			</config>

3. 创建控制器文件 app/code/local/Mage/Sintax/controllers/Adminhtml/MyformController.php

			Php代码  

			<?php  

			class Mage_Sintax_Adminhtml_MyformController extends Mage_Adminhtml_Controller_Action  

			{  

			    public function indexAction()  

			    {  

			        $this->loadLayout()->renderLayout();  

			    }  

			    public function postAction()  

			    {  

			        $post = $this->getRequest()->getPost();  

			        try {  

			            if (emptyempty($post)) {  

			                Mage::throwException($this->__('Invalid form data.'));  

			            }  

			            /* here's your form processing */  

			            $message = $this->__('Your form has been submitted successfully.');  

			            Mage::getSingleton('adminhtml/session')->addSuccess($message);  

			        } catch (Exception $e) {  

			            Mage::getSingleton('adminhtml/session')->addError($e->getMessage());  

			        }  

			        $this->_redirect('*/*');  

			    }  

			}

4. 为Form文件穿件Block类(这步是可选的)

文件名: app/code/local/Mage/Sintax/Block/Myform.php

5. Layout 文件

文件: app/design/adminhtml/default/default/layout/sintax.xml

			Xml代码  

			<?xml version="1.0"?>  

			<layout>  

			    <sintax_adminhtml_myform_index>  

			        <reference name="content">  

			            <block type="adminhtml/template" name="myform" template="sintax/myform.phtml"/>  

			        </reference>  

			    </sintax_adminhtml_myform_index>  

			</layout>

6. Form 模板页
文件: app/design/adminhtml/default/default/template/sintax/myform.phtml

			Html代码  

			<div class="content-header">  

			    <table cellspacing="0" class="grid-header">  

			        <tr>  

			            <td><h3><?php echo $this->__('My form title')?></h3></td>  

			            <td class="a-right">  

			                <button onclick="editForm.submit()" class="scalable save" type="button"><span>Submit my form</span></button>  

			            </td>  

			        </tr>  

			    </table>  

			</div>  

			<div class="entry-edit">  

			    <form id="edit_form" name="edit_form" method="post" action="<?php echo $this->getUrl('*/*/post')?>">  

			        <h4 class="icon-head head-edit-form fieldset-legend"><?php echo $this->__('This fieldset name')?></h4>  

			        <fieldset id="my-fieldset">  

			            <table cellspacing="0" class="form-list">  

			                <tr>  

			                    <td class="label"><?php echo $this->__('Field label')?> <span class="required">*</span></td>  

			                    <td class="input-ele"><input class="input-text required-entry" name="myform[myfield]" /></td>  

			                </tr>  

			            </table>  

			        </fieldset>  

			    </form>  

			</div>  

			<script type="text/javascript">  

			    var editForm = new varienForm('edit_form');  

			</script>

7. 翻译文件: app/locale/en_US/Mage_Sintax.csv

// this step is optional

8. Helper文件: app/code/local/Mage/Sintax/Helper/Data.php

			Php代码  

			<?PHP  

			class Mage_Sintax_Helper_Data extends Mage_Core_Helper_Abstract {  

			}  

			?>

以下几点说明：
1. config.xml中的acl标签的含义是什么？
2. helper类是必须的，为什么？
3. 本例block声明的类型为adminhtml/template, 不必声明相应的block类 (责任编辑：最模板)
