TYPO3 Extbase：如何 post 向控制器形成数据

Question

我无法将某些 Extbase 表单数据上传到控制器。在控制器中获取空值。这就是我所做的。

ext_localconf.php

        \TYPO3\CMS\Extbase\Utility\ExtensionUtility::configurePlugin(
        'Webtech.Wttempro2',
        'Jobdeskform',
        [
            'Jobdeskform' => 'createbewerber, formMailBs'
        ],
        // non-cacheable actions
        [
            'Jobdeskform' => 'createbewerber, formMailBs'
        ]
    );

ext_tables.php

        \TYPO3\CMS\Extbase\Utility\ExtensionUtility::registerPlugin(
        'Webtech.Wttempro2',
        'Jobdeskform',
        'Jobdesk Form'
    );

Jobdeskform/CreateBewerber.html

                        <f:form action="formMailBs" controller="Jobdeskform" object="{jobdeskform}" objectName="jobdeskform" method="post">
                        <label>Refno</label><br>
                        <input type="text" property="refno" required/><br>
                        <label>Vorname</label><br>
                        <input type="text" property="vorname" required/><br>
                        <f:form.button>Submit</f:form.button>
                    </f:form>

Model/Jobdeskform.php就是这么简单。它只是将成员变量与 getter 和设置器一起使用。

/**
 * 
 * Tempro data for jobdeskform
 * 
 */
class Jobdeskform extends \TYPO3\CMS\Extbase\DomainObject\AbstractEntity {
    /**
     * refno
     *
     * @var string
     */
    protected $refno = '';

    /**
     * vorname
     *
     * @var string
     */
    protected $vorname = '';


    /**
     * Returns the refno
     *
     * @return int $refno
     */
    public function getRefno()
    {
        return $this->refno;
    }

    /**
     * Sets the refno
     *
     * @param int $refno
     * @return void
     */
    public function setRefno($refno)
    {
        $this->refno = $refno;
    }

    /**
     * @return string
     */
    public function getVorname()
    {
        return $this->vorname;
    }

    /**
     * @param string $vorname
     * @return void
     */
    public function setVorname($vorname)
    {
        $this->vorname = $vorname;
    }

}

class JobdeskformController 扩展 \TYPO3\CMS\Extbase\Mvc\Controller\ActionController{

/**
 * action createBewerber
 *
 * @return void
 */
public function createbewerberAction()
{
    $baseuri = $this->request->getRequestUri();
    $parts = parse_url($baseuri);
    parse_str($parts['query'], $query);
    $this->view->assign('refno', htmlspecialchars($query['refno']));
}


/**
 * action formMailBs
 *
 * @param \Webtech\Wttempro2\Domain\Model\Jobdeskform $jobdeskform
 * @return void
 */
public function formMailBsAction(\Webtech\Wttempro2\Domain\Model\Jobdeskform $jobdeskform = NULL)
{

    \TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($jobdeskform, 'FormObject:');
    //\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($jobdeskform->refno, 'Refno:');
    //\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($refno, 'Refno:');
    //\TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump($vorname, 'Vorname:');

    die('DEBUG!!');


}

}

当我调试表单时，我在变量 $jobdeskform 中得到空值。我在控制器中输入了一些数据。为什么我在控制器调试输出中看不到输入的表单数据？也许我没有看到重要的东西。感谢您的帮助。

输入字段中没有名称属性：

您在 html 中的输入字段没有 "name" 属性。它们目前是使用纯 html 创建的，您可以使用 fluid form textfields:

创建字段

<f:form action="formMailBs" controller="Jobdeskform" objectName="jobdeskform" method="post">
    <label>Refno</label><br>
    <f:form.textfield property="refno" /><br>
    <label>Vorname</label><br>
    <f:form.textfield property="vorname" /><br>
    <f:form.button>Submit</f:form.button>
</f:form>

结果：

<input type="text" name="tx_example_jobdeskform[jobdeskform][refno]">
<input type="text" name="tx_example_jobdeskform[jobdeskform][vorname]">

调试 post 值的任何简单方法是在控制器中输出整个 $_POST 数组。对于您当前的输入字段，没有提交任何值（没有名称属性）。

/**
 * action formMailBs
 *
 * @param \Webtech\Wttempro2\Domain\Model\Jobdeskform $jobdeskform
 * @return void
 */
public function formMailBsAction(\Webtech\Wttempro2\Domain\Model\Jobdeskform $jobdeskform = NULL)
{
    debug($_POST); 
    die('DEBUG!!');
}

注意：您可以使用 shorthand 函数 debug 进行调试输出，而不是长 \TYPO3\CMS\Extbase\Utility\DebuggerUtility::var_dump

模型中变量类型不匹配：

在您的模型中，属性 $refno 定义为 string (@var string)

   /**
     * refno
     *
     * @var string
     */
    protected $refno = '';

稍后在您的 setter 和 getter 方法中将其定义为 integer:

   /**
     * Returns the refno
     *
     * @return int $refno
     */
    public function getRefno()
    {
        return $this->refno;
    }

    /**
     * Sets the refno
     *
     * @param int $refno
     * @return void
     */
    public function setRefno($refno)
    {
        $this->refno = $refno;
    }

注意：您可以通过添加基本的 validation error output.

来查找此类错误

<f:form.validationResults>
  <f:if condition="{validationResults.flattenedErrors}">
    <ul class="errors">
      <f:for each="{validationResults.flattenedErrors}" as="errors" key="propertyPath">
        <li>{propertyPath}
          <ul>
          <f:for each="{errors}" as="error">
            <li>{error.code}: {error}</li>
          </f:for>
          </ul>
        </li>
      </f:for>
    </ul>
  </f:if>
</f:form.validationResults>
<f:form action="formMailBs" controller="Jobdeskform" objectName="jobdeskform" method="post">
    <label>Refno</label><br>
    <f:form.textfield property="refno" /><br>
    <label>Vorname</label><br>
    <f:form.textfield property="vorname" /><br>
    <f:form.button>Submit</f:form.button>
</f:form>
