类似于教程的编辑操作不起作用
我遵循了ZF3教程并且我非常满意，但是我的控制器中的编辑操作缺少了。添加操作正常，而编辑操作则没有。可能我自己也看不到，所以我在这里发帖，寻求帮助，即使它是非常基本的。
我的模型与教程中的模型几乎相同，这里是其中的一部分：
public function exchangeArray(array $data)
{
$this->ProjectID= !empty($data['ProjectID']) ? $data['ProjectID'] : null;
$this->CI_Number= !empty($data['CI_Number']) ? $data['CI_Number'] : null;
$this->Description= !empty($data['Description']) ? $data['Description'] : null;
$this->Projectname= !empty($data['Projectname']) ? $data['Projectname'] : null;
$this->Shortcut= !empty($data['Shortcut']) ? $data['Shortcut'] : null;
$this->Component_Class= !empty($data['Component_Class']) ? $data['Component_Class'] : null;
}
public function getArrayCopy()
{
// echo var_dump(get_object_vars($this)
// );
//return get_object_vars($this);
return [
'ProjectID' => $this->ProjectID,
'CI_Number' => $this->CI_Number,
'Description' => $this->Description,
'Projectname' => $this->Projectname,
'Shortcut' => $this->Shortcut,
'Component_Class' => $this->Component_Class,
];
}
还有我的控制权：
public function editAction()
{
$id = (int) $this->params()->fromRoute('id', 0);
echo $id;
if (0 === $id) {
return $this->redirect()->toRoute('project', ['action' => 'add']);
}
else {
try {
$project = $this->projectTable->getProject($id);
} catch (\Exception $e) {
return $this->redirect()->toRoute('project', ['action' => 'index']);
}
$form = new ProjectForm();
$form->bind($project);
//$form->bind($project->current());
$form->get('submit')->setAttribute('value', 'save changes');
$request = $this->getRequest();
$viewData = ['ProjectID' => $id, 'form' => $form];
if (! $request->isPost()) {
return $viewData;
}
$form->setInputFilter($project->getInputFilter());
$form->setData($request->getPost());
if (! $form->isValid()) {
echo "nicht valide";
return $viewData;
}
else{
echo $project;
$this->projectTable->saveProject($project);
}
}
// Redirect to album list
// return $this->redirect()->toRoute('project', ['action' => 'index']);
}
这里是完成原因我的观点edit.phtml：
<?php
$title = 'projects';
$this->headTitle($title);
?>
<h1><?= $this->escapeHtml($title) ?></h1>
<?php
// This provides a default CSS class and placeholder text for the artist element:
$ProjectID= $form->get('ProjectID');
$ProjectID->setAttribute('class', 'form-control');
$ProjectID->setAttribute('placeholder', 'ProjectID');
$Projectname= $form->get('Projectname');
$Projectname->setAttribute('class', 'form-control');
$Projectname->setAttribute('placeholder', 'Projectname');
$CI_Number= $form->get('CI_Number');
$CI_Number->setAttribute('class', 'form-control');
$CI_Number->setAttribute('placeholder', 'CI_number');
$Shortcut= $form->get('Shortcut');
$Shortcut->setAttribute('class', 'form-control');
$Shortcut->setAttribute('placeholder', 'Shortcut');
$Description= $form->get('Description');
$Description->setAttribute('class', 'form-control');
$Description->setAttribute('placeholder', 'Description');
$Component_Class= $form->get('Component_Class');
$Component_Class->setAttribute('class', 'form-control');
$Component_Class->setAttribute('placeholder', 'Component_Class');
// This provides CSS classes for the submit button:
$submit = $form->get('submit');
$submit->setAttribute('class', 'btn btn-primary');
//$form->setAttribute('action', $this->url('project', ['action' => 'edit',])); //,'id'=> $id
$form->setAttribute('action', $this->url('project', [
'action' => 'edit',
'ProjectID' => $id,
]));
$form->prepare();
echo $this->form()->openTag($form);
?>
<?php // Wrap the elements in divs marked as form groups, and render the
// label, element, and errors separately within ?>
<div class="form-group">
<?= $this->formElement($ProjectID) ?>
<?= $this->formElementErrors()->render($ProjectID, ['class' => 'help-block']) ?>
</div>
<div class="form-group">
<?= $this->formLabel($CI_Number) ?>
<?= $this->formElement($CI_Number) ?>
<?= $this->formElementErrors()->render($CI_Number, ['class' => 'help-block']) ?>
</div>
<div class="form-group">
<?= $this->formLabel($Description) ?>
<?= $this->formElement($Description) ?>
<?= $this->formElementErrors()->render($Description, ['class' => 'help-block']) ?>
</div>
<div class="form-group">
<?= $this->formLabel($Projectname) ?>
<?= $this->formElement($Projectname) ?>
<?= $this->formElementErrors()->render($Projectname, ['class' => 'help-block']) ?>
</div>
<div class="form-group">
<?= $this->formLabel($Shortcut) ?>
<?= $this->formElement($Shortcut) ?>
<?= $this->formElementErrors()->render($Shortcut, ['class' => 'help-block']) ?>
</div>
<div class="form-group">
<?= $this->formLabel($Component_Class) ?>
<?= $this->formElement($Component_Class) ?>
<?= $this->formElementErrors()->render($Component_Class, ['class' => 'help-block']) ?>
</div>
<?php
echo $this->formSubmit($submit);
//echo $this->form->get('DCLID');
echo $this->formHidden($form->get('ProjectID'));
echo $this->form()->closeTag();
它会正确显示记录集，但不会将更改保存到数据库中，然后重定向到我的添加操作。我希望有人看到我所缺少的东西，即使这可能是一个愚蠢的错误。
EDIT1：这是我在index.phtml
中的路由链接 <a href="<?= $this->url('project', ['action' => 'edit', 'id' => $project->ProjectID]) ?>">Edit</a>
EDIT2：屏幕截图显示路由参数
EDIT3：描述测试问题
这里再次进行我的控制器编辑操作，以跟进：
public function editAction()
{
$id = (int) $this->params()->fromRoute('id', 0);
echo "variable id: ". $id;
if (0 === $id) {
//return $this->redirect()->toRoute('project', ['action' => 'index']);
echo "id = 0";
}
else {
try {
$project = $this->projectTable->getProject($id);
} catch (\Exception $e) {
return $this->redirect()->toRoute('project', ['action' => 'index']);
}
$form = new ProjectForm();
$form->bind($project);
//$form->bind($project->current());
$form->get('submit')->setAttribute('value', 'save changes');
var_dump(get_object_vars($project));
$request = $this->getRequest();
$viewData = ['ProjectID' => $id, 'form' => $form];
if (!$request->isPost()) {
return $viewData;
}
else {
$form->setInputFilter($project->getInputFilter());
$form->setData($request->getPost());
if (!$form->isValid()) {
echo "nicht valide";
return $viewData;
}
else{
echo "valide";
echo $project;
$this->projectTable->saveProject($project);
}
}
}
// Redirect to album list
// return $this->redirect()->toRoute('project', ['action' => 'index']);
}
我得到了vardump的输出，因此要编辑的项目将正确传递。如果我发送带有记录更改的表单，控制器将无法捕获它，则控制器操作会看到id = 0，因此将永远不会调用saveProject方法。根据我的理解，它可能与formvalid有关，因为在发送数据之后我来的时间永远不会超过if (0 === $id)。
编辑4：经过一些实际测试后，我认为它必定是一个路由问题。如果我通过浏览器手动提供路线，我将无法获得目标页面。如果我转储该值，它始终为NULL。因此，我认为这可能是我module.config.php中显示/更少问题的一个重要因素我在这里展示它因为我无法解决这个问题，我多次将胸罩计算在内并且我不会得到它。所以任何帮助都值得赞赏，它必须是一个非常简单的主题：

我目前正在usercontroller进行测试，但我在其他路由中遇到了同样的问题，所以我认为错误可能在此文件中。

答案 0 :(得分：0)
根据您的代码，似乎问题出在$id上。这意味着值为0，这就是重定向到project/add的原因。
$id = (int) $this->params()->fromRoute('id', 0);
echo $id;
if (0 === $id) {
return $this->redirect()->toRoute('project', ['action' => 'add']);
}
在您的视图脚本中，表单操作设置为project/edit/ProjectID/$id
$form->setAttribute('action', $this->url('project', [
'action' => 'edit',
'ProjectID' => $id,
]));
这就是您的控制器无法检索$this->params()->fromRoute('id', 0)的原因，因为表格会发送ProjectID参数而不是id。
因此，解决方案请调整您的表单（使用id）或您的控制器（使用ProjectID）。
答案 1 :(得分：0)
我终于解决了它。我的建议是对的，这是module.config.php的问题，我在错误的地方设置了一个endbracket。
在将其写入新的部分，完成并完成文件后，它现在可以正常工作。
