<?php   defined('BASEPATH') OR exit('No direct script access allowed');


function getCrud($table_name, $subject)
{
$CI =& get_instance();
$CI->load->database();
$crud = new grocery_Crud();
$crud->set_table($table_name);
$crud->set_subject($subject);
$crud->unset_read();
$crud->unset_clone();
$crud->where(array($table_name.'.flag' => '1'));
$crud->callback_delete(function ($primary_key) use ($table_name) {
return $CI->db->update($table_name, array('flag'=>'0'), array('id'=>$primary_key));
});
return $crud;
}
function oneToMany($table_name, $subject, $rel_table,$field='name')
{
$crud = getGrocreyCrud($table_name, $subject);
$crud->set_relation($rel_table.'_id', $rel_table, 'name', array('flag' => '1'));
$output = $crud->render();
return $output;
}

我无法使用 ci get 实例调用上述函数 getCrad。 还有其他方法吗？

返回 $CI->db->update($table_name， array('flag'=>'0'(， array('id'=>$primary_key((; 在控制器中使用这些代码行时($CI将在控制器中$this(我能够将标志设置为 0，但在帮助程序中它没有发生

Answer 1

可能以下应该有效

<?php 
defined('BASEPATH') OR exit('No direct script access allowed');

if(!function_exists('getCrud'))
{
function getCrud($table_name, $subject)
{
// some code
}
}
if(!function_exists('oneToMany'))
{
function oneToMany()
{
$CI =&get_instance();
$crud = getCrud($table_name, $subject);
return $crud ;
}
}

Answer 2

class Gc_script
{
public $CI;
public function __construct()
{
$this->CI =& get_instance();
$this->CI->config->item('base_url');
}
public function getGrocreyCrud($table_name, $read=null)
{
$crud = new grocery_Crud();
$crud->set_table($table_name);
$crud->set_subject(ucwords(str_replace('_', ' ', $table_name)));
$crud->callback_delete(function ($primary_key) use ($table_name) {
return  $this->CI->db->update($table_name, array('flag'=>'0'), array('id'=>$primary_key));
});
return $crud;
}
}

Answer 3

<?php 
defined('BASEPATH') OR exit('No direct script access allowed');

function getCrud($table_name, $subject)
{
// some code
}
function oneToMany()
{
$CI =&get_instance();
$crud = $CI->getCrud($table_name, $subject);
return $crud ;
}
