我有两个这样的表:
CREATE TABLE `tblFacilityHrs` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`uid` varchar(45) DEFAULT NULL,
`title` varchar(100) DEFAULT NULL,
`description` text,
PRIMARY KEY (`id`),
KEY `key_uid` (`uid`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=latin1$$
CREATE TABLE `tblFacilityHrsDateTimes` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`owner_uid` varchar(45) DEFAULT NULL,
`startDate` date DEFAULT NULL,
`endDate` date DEFAULT NULL,
`startTime` time DEFAULT NULL,
`endTime` time DEFAULT NULL,
`days` int(2),
`recurrence` int(1) DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `fk_fh_owneruid` (`owner_uid`),
CONSTRAINT `fk_fh_owneruid` FOREIGN KEY (`owner_uid`) REFERENCES `tblFacilityHrs` (`uid`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB AUTO_INCREMENT=52 DEFAULT CHARSET=latin1$$

在我的控制器文件夹中,我有一个名为 main.php 的文件,其中包含以下代码:
...
function fitnessSchedule()
{
$this->config->set_item('url_suffix', '');
$crud = new grocery_CRUD();
$crud->set_model('schedule_model');
$crud->set_table('tblFitnessClasses');
$crud->join_table('tblFitnessClasses','tblFitnessClassDateTimes');
$crud->columns('title','description','location','startDate','endDate','startTime', 'endTime', 'days', 'recurrance');
$crud->display_as('title','Event')
->display_as('description','Description')
->display_as('location','Location')
->display_as('startDate','Start Date')
->display_as('endDate','End Date')
->display_as('startTime','Start Time')
->display_as('endTime','End Time');
$crud->required_fields('title','location');
$crud->set_subject('Event');
$output = $crud->render();
$this->_example_output($output);
}
function _example_output($output = null)
{
$this->load->view('main_view', $output);
}
...
在我的模型文件夹中,我有这个:
<?php
class schedule_model extends grocery_CRUD_Model
{
function join_table($table1, $table2)
{
if($this->$table1 === null)
return false;
$select = "{$this->$table1}.*";
$select .=",$table2.startDate, $table2.endDate, $table2.startTime, $table2.endTime, $table2.days, $table2.recurrence";
if(!empty($this->relation))
foreach($this->relation as $relation)
{
list($field_name , $related_table , $related_field_title) = $relation;
$unique_join_name = $this->_unique_join_name($field_name);
$unique_field_name = $this->_unique_field_name($field_name);
if(strstr($related_field_title,'{'))
$select .= ", CONCAT('".str_replace(array('{','}'),array("',COALESCE({$unique_join_name}.",", ''),'"),str_replace("'","\\'",$related_field_title))."') as $unique_field_name";
else
$select .= ", $unique_join_name.$related_field_title as $unique_field_name";
if($this->field_exists($related_field_title))
$select .= ", {$this->$table1}.$related_field_title as '{$this->$table1}.$related_field_title'";
}
$this->db->select($select, false);
$this->db->join('uid', '$table2.owner_uid = $table1.uid');
$results = $this->db->get($this->$table1)->result();
return $results;
}
/* function join_table($table1, $table2)
{
$this->db->select('$table1.*');
$this->db->join('$table2','$table1.uid = $table2.owner_uid','left');
$this->db->get('$table1');
}*/
}
?>
我收到此错误:
致命错误:在第 234 行调用 C:\xampp\htdocs\codeigniter\application\controllers\main.php 中未定义的方法grocery_CRUD::join_table()
我基本上试图通过 UID(uid 到 owner_uid)将 tblFacilityHrs 与 tblFacilityHrsDateTimes 连接起来。我想一次显示两个表格,这样当用户编辑表格时,他们不仅可以编辑事件的名称/位置,还可以编辑其时间/日期等。
