致命错误：TableDisplayOptions :: load（）的声明必须与JTableInterface :: load（）的声明兼容

Question

我正在使用Joomla 3.3.1和名为JTAG成员目录的组件（旧版本很少）。 当我尝试进入组件的“ Display Options部分时，遇到以下错误：

Fatal error: Declaration of TableDisplayOptions::load() must be compatible with that of JTableInterface::load() in /home1/nm534555/public_html/mywebsite.org/administrator/components/com_jtagmembersdirectory/tables/displayoptions.php on line 139

当我打开这个文件，并找到线139，我只能看到右括号}如显示在下面的代码（全displayoptions.php文件）：

<?php

defined('_JEXEC') or die('Restricted access');

class TableDisplayOptions extends JTable
{

  var $id;
  var $display_phone_no;
  var $display_facebook_page;
  var $display_twitter_page;
  var $display_in_frontend;
  var $display_nr_email;
  var $display_nr_country;
  var $display_nr_city;
  var $display_nr_state;
  var $display_nr_phone_no;
  var $display_nr_facebook;
  var $display_nr_twitter;  
  //end

  /**

  var $display;

   *

  var $custom_fields;

  /**

  const CF_ALLOWED = 10;

  function __construct(&$db)

  function load($oid=null)

    if(!isset($from['display_gallery'])) $from['display_gallery'] = 0; 
    if(isset($from['auto_sync'])) $from['auto_sync'] = 1;
    parent::bind($from, $ignore);

    $this->_retrieveCustomFields();
  }

  function _retrieveOptions()
  {

    $query = 'SELECT * FROM `#__jtmb_display_options';

    $this->_db->setQuery($query);

    $this->display = $this->_db->loadObject();


  }

  function _retrieveCustomFields()
  {

  //  $fields = array();

 //  $k = $this->_tbl_key;

//    if ($this->$k)
  //  {
      $query = 'SELECT field_name, field_label, display_nr_cf FROM #__jtmb_custom_fields LIMIT '.self::CF_ALLOWED;

      $this->_db->setQuery($query);

      $fields = $this->_db->loadObjectList();
    //}

    if (count($fields) < self::CF_ALLOWED)
    {
      require_once 'customfields.php';
      while (count($fields) < self::CF_ALLOWED)
      {
        $fields[] = new TableCustomFields($this->_db);
      }
    }

    $this->custom_fields = $fields;
  }

function delete()
  {
      $query = 'DELETE  FROM `#__jtmb_display_options';
      $this->_db->setQuery($query);

      $this->_db->loadObject();
  }

} -----------------------------> This is line 139

?>

我想不通，我也尝试在不同的论坛上找到解决方案，但无济于事。 有人可以帮我解决这个问题吗？ 谢谢。

Answer 1

你的类TableDisplayOptions实现接口JTableInterface （通过JTable类，它TableDisplayOptions延伸）。 此接口使用某些参数声明方法load 。 由于它是一个接口，因此您必须接受与接口定义相同的参数。

由于JTable类已经实现了接口，因此只需更改TableDisplayOptions::load()即可接受所有参数，就像JTable::load()一样，然后将它们传递给父方法。
