【问题描述】：

我正在构建一个 Joomla 组件并尝试使用 Joomla 工具栏，问题是按钮无法正常工作，至少发布和取消发布按钮不是（编辑） - 当我使用工具中的发布或取消发布按钮时栏，页面重新加载，它给出了成功消息但状态保持不变。

这是我的代码：

表格文件

<?php
defined( '_JEXEC' ) or die("Restricted Access");

class WetvprogramschedulerTableDay extends JTable 
    public function __construct(&$db)
    
        parent::__construct('#__wetv_programs_days', 'program_day_id', $db);
    

?>

单记录模型

<?php
defined( '_JEXEC' ) or die("Restricted Access");

jimport('joomla.application.component.modeladmin');

class WetvprogramschedulerModelDay extends JModelAdmin 
    public function getTable($type = 'Day', $prefix = 'WetvprogramschedulerTable', $config = array()) 
        return JTable::getInstance($type, $prefix, $config);
    

    public function getForm($data = array(), $loadData = true) 
        $form = $this->loadForm();

        return $form;
    

?>

编辑

列表模型

<?php
defined( '_JEXEC' ) or die("Restricted Access");

jimport('joomla.application.component.modellist');

class WetvprogramschedulerModelDays extends JModelList 
    public function __construct($config = array())

            $config['filter_fields'] = array(
                'program_day',
                'program_day_image',
                'published'
            );
        

        parent::__construct($config);
    

    public function getItems() 
        // Run the query returned from getListQuery()
        $items = parent::getItems();

        // Prepare urls for View
        // Doing this means we don't have to do it in the view
        foreach ($items as &$item) 
            $item->url = 'index.php?option=com_wetvprogramscheduler&amp;task=day.edit&amp;program_day_id=' . $item->program_day_id;
        

        return $items;
    

    public function getListQuery() 
        $query = parent::getListQuery();

        $query->select('*');
        $query->from('#__wetv_programs_days');

        // use state obtained from populateState()
        $published = $this->getState('filter.published');

        if ($published == '') 
            $query->where('(published = 1 OR published = 0)');
         else if ($published != '*') 
            $published = (int) $published;
            $query->where("(published = '$published')");
        

        $search = $this->getState('filter.search');

        $db = $this->getDbo();

        if (!empty($search)) 
            $search = '%' . $db->getEscaped($search, true) . '%';

            $field_searches =
                "(program_day_image LIKE '$search' OR " .
                "program_day LIKE '$search')";

            $query->where($field_searches);
        

        // Column ordering
        $orderCol = $this->getState('list.ordering');
        $orderDirn = $this->getState('list.direction');

        if ($orderCol != '') 
            $query->order($db->getEscaped($orderCol.' '.$orderDirn));
        


        return $query;
    

    protected function populateState($ordering = null, $direction = null) 
        $search = $this->getUserStateFromRequest($this->context.'.filter.search', 'filter_search');
        $this->setState('filter.search', $search);

        /*
         *Check both both session and form variable to see if
         *There is a value for the filter_published variable
        */
        $published = $this->getUserStateFromRequest($this->context.'.filter.published', 'filter_published');
        // If filter_published value, set it in model state.
        //so we can get value when we get state.
        $this->setState('filter.published', $published);

        parent::populateState($ordering, $direction);

控制器

<input type="hidden" name="task" value="" />
<input type="hidden" name="boxchecked" value="0" />

这是表的 sql 语句。

CREATE TABLE IF NOT EXISTS #__wetv_programs_days (
program_day_id BIGINT(20) NOT NULL AUTO_INCREMENT,
program_day VARCHAR(9) NOT NULL,
program_day_image VARCHAR(255) NOT NULL,
program_day_access int(11) DEFAULT '1',
program_day_alias varchar(255) DEFAULT NULL,
published tinyint(1) DEFAULT '0',
checked_out int(11) DEFAULT '0',
checked_out_time datetime DEFAULT '0000-00-00 00:00:00',
program_day_timestamp TIMESTAMP DEFAULT CURRENT_TIMESTAMP,

);

【问题讨论】：

当您说“无法正常工作”时，究竟发生了什么？按钮没有响应还是页面重新加载但状态保持不变？

后者 - 页面重新加载但状态保持不变。

能否添加 mysql 表的 create 语句，以便我们查看表的结构？

@cppl - 抱歉我回复晚了。我已经在问题中添加了声明。

我刚刚意识到你已经为WetvprogramschedulerModelDay 设置了模型，你可以为WetvprogramschedulerModelDays 设置模型

【参考方案1】：

复选框单元格中 default.php 的 progam_day_id 中缺少“r”。

应该是program_day_id
