本文实例讲述了Yii不依赖Model的表单生成器用法。分享给大家供大家参考。具体实现方法如下:
默认的Yii的表单生成器只需要这样就可以了:
$form = new CForm('application.views.site.loginForm', $model);
默认生成的表单的label是根据$model->attributes来显示的,所以我做了2件事:
1.继承CFormInputElement覆盖renderLabel方法,将label显示成自己配置的element的label
2.继承CForm覆盖renderElement方法,$element instanceof UCFormInputElement,并覆盖render方法,将Elements和getButtons循环输出
直接上代码:
app/protected/extensions/UCForm.php
<?php /** * @author Ryan <yuansir@live.cn/yuansir-web.com> */ class UCForm extends CForm { public function render() { $output = $this->renderBegin(); foreach ($this->getElements() as $element) { $output .= $element->render(); } foreach ($this->getButtons() as $button) { $output .= $button->render(); } $output .= $this->renderEnd(); return $output; } public function renderElement($element) { if (is_string($element)) { if (($e = $this[$element]) === null && ($e = $this->getButtons()->itemAt($element)) === null) return $element; else $element = $e; } if ($element->getVisible()) { //UCFormInputElement 代替 CFormInputElement if ($element instanceof UCFormInputElement) { if ($element->type === 'hidden') return "<div style="visibility:hidden">n" . $element->render() . "</div>n"; else return "<div class="row field_{$element->name}">n" . $element->render() . "</div>n"; } else if ($element instanceof CFormButtonElement) return $element->render() . "n"; else return $element->render(); } return ''; } }
<?php /** * @author Ryan <yuansir@live.cn/yuansir-web.com> */ class PlayerSearchController extends Controller { public function actionIndex() { $config = array( 'class' => 'ddd', 'action'=>'', 'elements' => array( '<br><br>', 'username' => array( 'label'=>'用户名啊',//注意这里的label 'type' => 'text', 'maxlength' => 32, 'value' => '' ), '<br><br>', 'password' => array( 'label'=>'昵称啊',//注意这里的label 'type' => 'password', 'maxlength' => 32, 'value' => '' ), ), 'buttons' => array( 'login' => array( 'type' => 'submit', 'label' => 'Login', ), ), ); $model = new CFormModel(); $form = new UCForm($config, $model); $this->render('index', compact('form')); } }
希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
