在PHP中保存项目（无效名称）时出错

Question

我正在使用Zoo CCK，并且弄乱了足够长的代码以使它看起来像我希望的样子。但是，当我提交该项目时，我收到一个我无法弄清楚的错误（标题中）。

为了减少混淆，我应该提及我对该文件所作的编辑是为$ message添加零件以及识别它的任何相关代码。

任何帮助，将不胜感激。这里是下面的文件代码：

错误：错误保存项目（无效的名称）

<?php 

// no direct access 
defined('_JEXEC') or die('Restricted access'); 

// register ElementOption class 
App::getInstance('zoo')->loader->register('ElementOption', 'elements:option/option.php'); 
// register ElementRepeatable class 
App::getInstance('zoo')->loader->register('ElementRepeatable', 'elements:repeatable/repeatable.php'); 
/* 
Class: ElementSelect 
    The select element class 
*/ 

class ElementMessage extends ElementOption implements iSubmittable { 

/* 
    Function: edit 
     Renders the edit form field. 

    Returns: 
     String - html 
*/ 
public function edit(){ 

    $this->app->document->addStylesheet('elements:message/assets/css/submission.css'); 
    // init vars 
    $options_from_config = $this->config->get('option', array()); 
    $multiple   = $this->config->get('multiple'); 
    $default    = $this->config->get('default'); 
    $name    = $this->config->get('name'); 
    $message   = $this->get('message'); 

    if (count($options_from_config)) { 

     // set default, if item is new 
     if ($default != '' && $this->_item != null && $this->_item->id == 0) { 
      $this->set('option', $default); 
     } 

     $options = array(); 
     if (!$multiple) { 
      $options[] = $this->app->html->_('select.option', '', '-' . JText::sprintf('Select %s', $name) . '-'); 
     } 
     foreach ($options_from_config as $option) { 
      $options[] = $this->app->html->_('select.option', $option['value'], $option['name']); 
     } 

     $style = $multiple ? 'multiple="multiple" size="5"' : ''; 

     $html[] = $this->app->html->_('select.genericlist', $options, $this->getControlName('option', true), $style, 'value', 'text', $this->get('option', array())); 
     $html[] = $this->app->html->_('control.text', $this->getControlName('Message'), $this->get('message'), 'name="message" size="30" maxlength="255" placeholder="'.JText::_('Message').'"'); 

     // workaround: if nothing is selected, the element is still being transfered 
     $html[] = '<input type="hidden" name="'.$this->getControlName('select').'" value="1" />'; 

     return implode("\n", $html); 
    } 

    return JText::_("There are no options to choose from."); 
} 
public function hasValue($params = array()) { 

    $message = $this->get('message'); 
    return !empty($message); 
} 
} 

Answer 1

尝试改变：

$message   = $this->get('message'); 

到

$message   = $this->config->get('message');
