Хорошо, я нашел решение проблемы.Возможно, он не идеален и, вероятно, нуждается в некотором рефакторинге, но каждый, я думаю, поймет принцип этого решения:
В /application/models/Grocery_crud_model.php мы должны добавить две функции:
function group_start()
{
$this->db->group_start();
}
function group_end()
{
$this->db->group_end();
}
В /application/libraries/Grocery_CRUD.php мы добавляем:
public function whereFix($key, $value = NULL, $escape = TRUE)
{
$this->whereFix[] = array($key,$value,$escape);
return $this;
}
В том же файле мы добавляем цикл для создания условий whereFix и закрытия для других типов терминов с помощью group_start () и group_end (),Фактически мы можем заменить функции get_list () и get_total_results ():
protected function get_list()
{
if(!empty($this->whereFix))
foreach($this->whereFix as $where)
$this->basic_model->where($where[0],$where[1],$where[2]);
if(!empty($this->order_by))
$this->basic_model->order_by($this->order_by[0],$this->order_by[1]);
if(!empty($this->where)){
$this->basic_model->group_start();
foreach($this->where as $where)
$this->basic_model->where($where[0],$where[1],$where[2]);
$this->basic_model->group_end();
}
if(!empty($this->or_where)){
$this->basic_model->group_start();
foreach($this->or_where as $or_where)
$this->basic_model->or_where($or_where[0],$or_where[1],$or_where[2]);
$this->basic_model->group_end();
}
if(!empty($this->like)){
$this->basic_model->group_start();
foreach($this->like as $like)
$this->basic_model->like($like[0],$like[1],$like[2]);
$this->basic_model->group_end();
}
if(!empty($this->or_like)){
$this->basic_model->group_start();
foreach($this->or_like as $or_like)
$this->basic_model->or_like($or_like[0],$or_like[1],$or_like[2]);
$this->basic_model->group_end();
}
if(!empty($this->having))
foreach($this->having as $having)
$this->basic_model->having($having[0],$having[1],$having[2]);
if(!empty($this->or_having))
foreach($this->or_having as $or_having)
$this->basic_model->or_having($or_having[0],$or_having[1],$or_having[2]);
if(!empty($this->relation))
foreach($this->relation as $relation)
$this->basic_model->join_relation($relation[0],$relation[1],$relation[2]);
if(!empty($this->relation_n_n))
{
$columns = $this->get_columns();
foreach($columns as $column)
{
//Use the relation_n_n ONLY if the column is called . The set_relation_n_n are slow and it will make the table slower without any reason as we don't need those queries.
if(isset($this->relation_n_n[$column->field_name]))
{
$this->basic_model->set_relation_n_n_field($this->relation_n_n[$column->field_name]);
}
}
}
if($this->theme_config['crud_paging'] === true)
{
if($this->limit === null)
{
$default_per_page = $this->config->default_per_page;
if(is_numeric($default_per_page) && $default_per_page >1)

Надеюсь, этот фрагмент кода будет кому-то полезен.
