Question

我搜索了很多但找不到问题的答案。 set_value()表单方法无法使用GET函数，而POST表单方法正在使用MySQL。我正在尝试从GET获取行，我想使用<?=form_open('employee_registration/search_employee', ['role'=>'form','method'=>'GET']);?> <div class="row"> <div class="col-sm-3"> <div class="form-group"> <label>R. No.<span class="required">*</span></label> <input class="form-control" placeholder="R. No." name="srch_r_no" id="srch_r_no" value="<?=set_value('srch_r_no');?>"> </div> </div> <div class="col-sm-3"> <div class="form-group"> <label>Name<span class="required">*</span></label> <input class="form-control" placeholder="Name" name="srch_e_name" id="srch_e_name" value="<?=set_value('srch_e_name');?>"> </div> </div> </div> <button type="submit" class="btn btn-primary" name="srch_btn">Search <span class="fa fa-search"></span></button> <?=form_close();?>方法。有人可以帮忙吗？

视图：

public function search_employee()
{
    $get = $this->input->get();
    unset($get['srch_btn']);
    $table = $this->md_emp_reg->search_employee($get);
    $this->index('view',$table);
}

控制器：

public function search_employee($get)
{
    $parameters = $this->filter_values($get,"search");
    $query = "CALL `sp_select_employee_details`(".$parameters.");";
    $grid = $this->table($query);
    return $grid;
}

public function filter_values($arr,$type)
{
    $arr_keys = array_keys($arr);
    $filtered_values = "";

    for ($i=0; $i < count($arr); $i++)
    {
        if ($arr[$arr_keys[$i]] == "" && $type == "search")
        {
            $arr[$arr_keys[$i]] = "";
        }
        elseif($arr[$arr_keys[$i]] == "" && $type != "search")
        {
            $arr[$arr_keys[$i]] = NULL;
        }

        $filtered_values .= $this->db->escape($arr[$arr_keys[$i]]).",";
    }

    return rtrim($filtered_values,',');
}

public function table($query)
{
    $result = $this->db->query($query);
    $r_arr = $result->result_array();
    $result_fields_name = $result->list_fields();
    $result_num_fields = $result->num_fields();
    $result_num_rows = $result->num_rows();

    $table = '<table width="100%" class="table table-condensed table-striped table-bordered table-hover" id="dataTables-example"><thead><tr>';

    for ($a=0; $a < $result_num_fields; $a++)
    { 
        $table .= "<th>".$result_fields_name[$a]."</th>";
    }

    $table .="</tr></thead><tbody>";

    for ($i=0; $i < count($r_arr) ; $i++)
    {
        $table .= "<tr>";

        for ($j=0; $j < $result_num_fields ; $j++)
        {
            $table .= "<td>".$r_arr[$i][$result_fields_name[$j]]."</td>";
        }

        $table .= "</tr>";
    }

    $table .="</tbody></table>";

    $this->db->close();
    return $table;
}

模型：

colModel: $scope.colModelValue

这是功能：

function set_value($field, $default = '', $html_escape = TRUE)
{
    $CI =& get_instance();

    $value = (isset($CI->form_validation) && is_object($CI->form_validation) && $CI->form_validation->has_rule($field))
        ? $CI->form_validation->set_value($field, $default)
        : $CI->input->post($field, FALSE);

    isset($value) OR $value = $default;
    return ($html_escape) ? html_escape($value) : $value;
}

删除form_validation逻辑，因为它对我们没用，我们得到：

function set_value($field, $default = '', $html_escape = TRUE)
    {
        $CI =& get_instance();

        $value = $CI->input->post($field, FALSE);

        isset($value) OR $value = $default;
        return ($html_escape) ? html_escape($value) : $value;
    }

交换帖子我们可以创建自己的帮助器set_value_get()，将它保存在帮助器中，加载帮助器.etc。：

function set_value_get($field, $default = '', $html_escape = TRUE)
    {
        $CI =& get_instance();

        $value = $CI->input->get($field, FALSE);

        isset($value) OR $value = $default;
        return ($html_escape) ? html_escape($value) : $value;
    }

用法与set_value相同。

CI set_value不适用于get form方法
