Zend Form 实例化在白屏死机中默默失败
Zend 新手尝试配置和使用 Zend_Form。
仅供记录,我使用的是 Zend Framework 版本:1.11.1,在 Win XP 上运行 Apache 2.something。我正在开发一个网站,该网站大部分工作都很好。 (其他人开始了它。我必须扩展它)。
我在表单领域遇到了麻烦,正在尝试引入 Zend_Form,希望这能以某种方式简化问题。但尝试使用 Zend_Form 会带来它自己的问题。
当我尝试实例化第一个测试表单时,我遇到了死机白屏——甚至没有错误消息。
数据如下:
Dir Structure:
MYAPPNAME
....controllers
....forms
....models
....services
....views
Bootstrap.php 包含:
protected function _initAutoLoading()
{
$loader = new Zend_Loader_Autoloader_Resource(array(
'namespace' => 'MYAPPNAME',
'basePath' => APPLICATION_PATH . '/modules/MYAPPNAME',
));
$loader->addResourceTypes(array(
'model' => array(
'path' => 'models',
'namespace' => 'Model'),
'form' => array(
'path' => 'forms',
'namespace' => 'Form'),
'service' => array(
'path' => 'services',
'namespace' => 'Service')));
}
这对于名称如下的模型来说效果很好:
class MYAPPNAME_Model_DataRecordName extends Doctrine_Record
{
etc...
但对于表单来说,它似乎严重失败......尽管请注意,这是我第一次使用 Zend_Form。
我的表单在文件 MYAPPNAME/forms/Formtest.php 中定义:
<?php
class MYAPPNAME_Form_Formtest extends Zend_Form
{
public function init($action){
$this->setAction($action)
->setMethod('post')
->setAttrib('id', 'formtestForm');
$email = $this->addElement( 'text', 'email',
array('label', => 'EMail'));
)
$submit = $this->addElement('submit', 'Submit and Be Free!');
}// End init
} // End class def
该表单显示在定义为的视图中:
<div class=""testForm">
<p style="margin-top:20px; margin-bottom:10px"">Explanatory Text</p>
<h2>This is a Form Test</h2>
<?php echo $this->formResponse; ?>
<?php echo $this->form; ?>
<hr>
<p>FORM ABOVE THIS BAR</p>
</div>
该视图工作正常。
它由一个操作(在工作控制器中)管理,定义为:
public function formtestAction(){
echo "formtestAction: ENTERED";
$form = new MYAPPNAME_Form_Formtest('ThisController/formtest2');
//$form = "<p>GARBAGE DATA</p>";
if(!empty($form)){$this->view->form = $form;}
else{
$form = "<p>THE FORM VAR IS EMPTY</p>";
$this->view->form = $form;
$formResponse = "<p>INSTANTIATION FAILED</p>";
$this->view->formResponse = $formResponse;
}
}
public function formtest2Action(){
echo "formtest2Action: ENTERED";
}
如果我注释掉表单实例化和垃圾数据行,我会在视图中获得有效的输出。如果我将 $form 设置为“垃圾数据”,我也会得到有效的可预测输出。
然而,当我尝试实例化表单对象时,我得到了仅包含“formtestAction:ENTERED”(来自顶部的 echo 语句)的死亡白屏。
我慢慢地发疯了。
我无法弄清楚这是一个自动加载器问题、一个路由问题、一个对象实例化问题还是什么。
我非常感谢任何建议。
感谢您的阅读。
Zend newbie trying to configure and use Zend_Form.
Just for the record I'm on Zend Framework Version: 1.11.1 on Win XP running Apache 2.something. I'm working on a site which for the most part works just fine. (Somebody else started it. I have to extend it).
I am having trouble in the area of forms and am trying to introduce Zend_Form in the hope that this will somehow simplify matters. But trying to use Zend_Form is presenting problems of it's own.
When I try to instantiate the first test form, I'm getting the white screen of death -- without even an error message.
Data as follows:
Dir Structure:
MYAPPNAME
....controllers
....forms
....models
....services
....views
Bootstrap.php contains:
protected function _initAutoLoading()
{
$loader = new Zend_Loader_Autoloader_Resource(array(
'namespace' => 'MYAPPNAME',
'basePath' => APPLICATION_PATH . '/modules/MYAPPNAME',
));
$loader->addResourceTypes(array(
'model' => array(
'path' => 'models',
'namespace' => 'Model'),
'form' => array(
'path' => 'forms',
'namespace' => 'Form'),
'service' => array(
'path' => 'services',
'namespace' => 'Service')));
}
This works fine for models with names like:
class MYAPPNAME_Model_DataRecordName extends Doctrine_Record
{
etc...
But it seems to be failing miserably for forms ... although mind you, this is my first pass at using Zend_Form.
My form is defined in file MYAPPNAME/forms/Formtest.php:
<?php
class MYAPPNAME_Form_Formtest extends Zend_Form
{
public function init($action){
$this->setAction($action)
->setMethod('post')
->setAttrib('id', 'formtestForm');
$email = $this->addElement( 'text', 'email',
array('label', => 'EMail'));
)
$submit = $this->addElement('submit', 'Submit and Be Free!');
}// End init
} // End class def
The form is being displayed in a view defined as:
<div class=""testForm">
<p style="margin-top:20px; margin-bottom:10px"">Explanatory Text</p>
<h2>This is a Form Test</h2>
<?php echo $this->formResponse; ?>
<?php echo $this->form; ?>
<hr>
<p>FORM ABOVE THIS BAR</p>
</div>
The view works just fine.
It is being managed by an action (in a working controller) defined as:
public function formtestAction(){
echo "formtestAction: ENTERED";
$form = new MYAPPNAME_Form_Formtest('ThisController/formtest2');
//$form = "<p>GARBAGE DATA</p>";
if(!empty($form)){$this->view->form = $form;}
else{
$form = "<p>THE FORM VAR IS EMPTY</p>";
$this->view->form = $form;
$formResponse = "<p>INSTANTIATION FAILED</p>";
$this->view->formResponse = $formResponse;
}
}
public function formtest2Action(){
echo "formtest2Action: ENTERED";
}
If I comment out both the form instantiation and the garbage data lines, I get valid output in the view. If I set $form to "GARBAGE DATA" I also get valid predictable output.
However when I try to instantiate the form object I get the white screen of death containing only "formtestAction: ENTERED" (from the echo statement at the top.)
I am going slowly mad.
I can't figure out if this is an autoloader problem, a routing problem, an object instantiation problem, or what.
I'd be very much obliged for any advice.
Thanks for reading.

在使用 Zends 时,我已经多次遇到过这种情况,而且通常是多余的逗号,这很烦人。在
... 'basePath' =>应用程序路径。 '/modules/MYAPPNAME',));
它看起来就像其中一个。只是快速浏览一下,但无论如何您都可以检查一下。
哈特哈,

With Zends, I've run into that several times, and it usually is something annoying as a superflous comma. In
... 'basePath' => APPLICATION_PATH . '/modules/MYAPPNAME',));
it looks just like on of those. Only a quick look, but you might check it anyway.
HTH,

mtoepper:非常接近。好捕获!
这确实是一个额外的逗号,只是它出现在 Form 类定义中——阻止了成功的对象实例化。
这些无声的失败非常烦人。
mtoepper: Very close. Good catch!
It was indeed an extra comma, only it was in the Form class definition -- preventing successful object instantiation.
These silent failures are VERY annoying.
