Question

当我在主索引上提交表单时，我试图将变量调用$store_id传递给同一控制器上的一个函数，名为 do_upload_image（$ store_id）

我正在尝试获取插入我的商店表格中的最后一个ID。

加载另一个模型函数$ this-＆gt; example_model-＆gt; add（$ store_id）;但是在同一个控制器上的另一个功能上执行它时不会。

错误输出

Column 'store_id' cannot be null

INSERT INTO `setting` (`store_id`, `group`, `key`, `value`) VALUES (NULL, 'config', 'config_image', 'flagnz.png')

喜欢这样

$store_id = $this->model_store_add->add_store(); // this way should let me get id that was inserted.

$this->do_upload_image($store_id);

我怎么能让$ store_id通过同一个控制器上的另一个函数？我有一个模型试图将商店ID传递给do_upload_image

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

class Store_add extends MX_Controller {

public $store_id;

public function __construct() {
    parent::__construct();

    if (!$this->session->userdata('isLogged')) {
        redirect('admin');
    }

    $this->load->model('admin/setting/model_store_add');
    $this->load->model('admin/setting/model_store_get');

    $this->lang->load('admin/setting/store_add', $this->settings->get('config_admin_language'));
}

public function index() 

    $this->load->library('form_validation');

    $this->form_validation->set_rules('config_image', 'Store Image','callback_do_upload_image');

    if ($this->form_validation->run($this) == FALSE) {

        return $this->load->view('setting/store_add.tpl');

    } else {

        // $store id lets me get id that was inserted from store table
        $store_id = $this->model_store_add->add_store();

        $this->model_store_add->add_config_meta_title($store_id); // Works

        $this->do_upload_image($store_id);


        $this->session->set_flashdata('success', $this->lang->line('text_success'));

        redirect('admin/setting/store');

    }
}

public function do_upload_image($store_id) {
    $config['upload_path'] = './image/upload/';
    $config['allowed_types'] = $this->settings->get('config_file_ext_allowed');
    $config['max_size'] = $this->settings->get('config_file_max_size');
    $config['overwrite'] = $this->settings->get('config_file_overwrite');
    $config['max_width'] = '*';
    $config['max_height'] = '*';

    $this->load->library('upload', $config);
    $this->upload->initialize($config);

    if (is_uploaded_file($_FILES['config_image']['tmp_name'])) {

        if (!$this->upload->do_upload('config_image')) {

            $this->form_validation->set_message('do_upload_image',  $this->upload->display_errors('<b>config_image</b>' .' '));

            return false;

        } else {

            $resize_data = $this->upload->data();

            $config_resize['image_library'] = 'gd2';
            $config_resize['source_image'] = './image/upload/' . $resize_data['file_name'];
            $config_resize['new_image'] =  './image/cache/' . $resize_data['file_name'];
            $config_resize['maintain_ratio'] = false;
            $config_resize['create_thumb'] = false;
            $config_resize['width'] = 100;
            $config_resize['height'] = 100;

            $this->load->library('image_lib', $config_resize);
            $this->image_lib->initialize($config_resize);

            if (!$this->image_lib->resize()) {

                $this->sessions->set_flashdata('error', $this->image_lib->display_errors());

                redirect('admin/setting/setting');

            } else {

                $this->model_store_add->add_config_image($store_id, $this->upload->data());

            }
        }
    }
}
}

do_upload_image上的模型

public function add_config_image($store_id = 0, $file_data = array()) {

    $file_data = $this->upload->data();

    $data = array(
        'store_id' => $store_id,
        'group' => "config",
        'key' => "config_image",
        'value' => $file_data['file_name']
    );

    $this->db->set($data);
    $this->db->insert($this->db->dbprefix. 'setting');

}

模型添加

public function add_store() {
    $data = array(
        'name' => $this->input->post('config_name'),
        'url' => $this->input->post('config_url'),
        'ssl' => $this->input->post('config_ssl')
    );

    $this->db->set($data);
    $this->db->insert_id();
    $this->db->insert($this->db->dbprefix . 'store');
    return $this->db->insert_id();
}

我缩小了自己的问题。我需要第二次传递商店ID作为if语句，现在所有工作

我刚刚删除了resize函数进行测试，看看是否存在问题，但现在没有原因。还需要在回调函数下面添加return true。

public function do_upload_image($store_id) {
    $config['upload_path'] = './image/upload/';
    $config['allowed_types'] = $this->settings->get('config_file_ext_allowed');
    $config['max_size'] = $this->settings->get('config_file_max_size');
    $config['overwrite'] = $this->settings->get('config_file_overwrite');
    $config['max_width'] = '*';
    $config['max_height'] = '*';

    $this->load->library('upload', $config);
    $this->upload->initialize($config);

    if ($this->upload->do_upload('config_image')) {

        if ($store_id) {

            $this->model_store_add->add_config_image($store_id, $this->upload->data());

        }

        return true;

    } else {

        return false;

    }

}

通过函数传递变量
