Question

我想将Bootstrap Treeview插件转换为CodeIgniter，它在核心PHP上正常运行但是当我将其转换为CodeIgniter时，它只显示数组结果。

fetch.php - 控制器

<?php

class Fetch extends MY_Controller {

    public function index() {

        $this->load->view('dashboard');
        // $query (= " SELECT * FROM country_state_city ";
        $query = $this->db->query("SELECT * FROM country_state_city ");
        // (" SELECT * FROM country_state_city ")->result_array() ;

        //$output = array();
        foreach ($query->result_array() as $row) {
            $sub_data["id"] = $row["id"];
            $sub_data["name"] = $row["name"];
            $sub_data["text"] = $row["name"];
            $sub_data["parent_id"] = $row["parent_id"];
            $data[] = $sub_data;

        }


        foreach ($data as $key => &$value) {
            $output[$value["id"]] = &$value;
        }

        foreach ($data as $key => &$value) {
            if ($value["parent_id"] && isset($output[$value["parent_id"]])) {
                $output[$value["parent_id"]]["nodes"][] = &$value;
            }
        }

        foreach ($data as $key => &$value) {
            if ($value["parent_id"] && isset($output[$value["parent_id"]])) {
                unset($data[$key]);
            }
        }

如果要使用ajax请求加载数据，则无需在index（）函数中加载它。

您必须在index（）中加载唯一的视图，并为树视图创建另一个函数，如下所示：

您在页面加载时加载所有数据，然后进行不正确的ajax调用。

<强>控制器：

<?php

class Test_c extends CI_Controller {

    public function index() {

        $this->load->view('test');


    }
    function tree() {
        // $query (= " SELECT * FROM country_state_city ";
        $query = $this->db->query("SELECT * FROM country_state_city ");
        // (" SELECT * FROM country_state_city ")->result_array() ;

        //$output = array();
        foreach ($query->result_array() as $row) {
            $sub_data["id"] = $row["id"];
            $sub_data["name"] = $row["name"];
            $sub_data["text"] = $row["name"];
            $sub_data["parent_id"] = $row["parent_id"];
            $data[] = $sub_data;

        }


        foreach ($data as $key => &$value) {
            $output[$value["id"]] = &$value;
        }

        foreach ($data as $key => &$value) {
            if ($value["parent_id"] && isset($output[$value["parent_id"]])) {
                $output[$value["parent_id"]]["nodes"][] = &$value;
            }
        }

        foreach ($data as $key => &$value) {
            if ($value["parent_id"] && isset($output[$value["parent_id"]])) {
                unset($data[$key]);
            }
        }

        echo json_encode($data);
    }
}

?>

试试这样。有用。其他事情是正确的。

希望您使用我的解决方案解决您的错误。
