Question

我在codeigniter工作。我想在父代理下显示父代理及其子代理。我的父代理数据显示如下

Array
(
[0] => stdClass Object
    (
        [id] => 1
        [Introducer_code] => 0
        [Designation] => 2
        [Cader] => 
        [Code] => 
        [Name] => Vinod
        [Area] => 
        [D_W_S] => Rajendra
        [Gender] => Male
        [Dob] => 2014-12-01
        [age] => 25
        [mobile_no] => 123456789
        [Village] => vadodara road
        [city] => vadodara
        [District] => vadodara
        [State] => 1
        [Pincode] => 391212
        [PAN] => BCD1234587
        [Nominee] => Rajendra
        [N_Relation] => Father
        [N_age] => 35
        [D_O_J] => 2014-12-22
        [amount] => 100
        [Bank_acc] => 0123467
        [Bank_add] => vadodara
        [branch_id] => 102
        [uname] => 
        [pass] => 
        [enc_pass] => d41d8cd98f00b204e9800998ecf8427e
        [agent_id] => 
        [profile_Pic] => 
    )

)

这里Introducer_code是父代理代码。现在我想显示引入代码为id为1的子代理。

我的代码是这样的。

public function get_agent_tree_commision()
{   

    $query = $this->db->query("select * from agent where id = '1'");

    $result = $query->result();
    echo "<pre>";
    print_r($result);

    $roles = array();

    foreach($result as $key=>$value)
    {   

        if($result[$key]->Introducer_code != 0)
        {

            $role = array();

            $role['id'] = $result[$key]->id;

            $role['Name'] = $result[$key]->Name;

            $children = $this->build_child($result, $result[$key]->id); 

            //print_r($children);

            if( !empty($children) ) {

                $role['children'] = $children;

            }

            $roles[] = $role;

        }

    }

    return $roles;

    //$this->load->view("cashier/get_agent_tree_commision");
}

public function build_child($result, $parent)
{
    $roles = array();       

    foreach($result as $key => $val) {

        if($result[$key]->Introducer_code == $parent) {
            $role = array();

            $role['role_id'] = $result[$key]->id;
            $role['role_name'] = $result[$key]->Name;

            $children = $this->build_child($result, $result[$key]->id);

            if( !empty($children) ) {                   

                $role['children'] = $children;

            }
            $roles[] = $role;

            return $roles;
        }
    }

}

我有四个孩子代理，其介绍人代码是1.结果就是这样。

当我运行此代码时，它什么也没显示。现在，我应该在代理下写代码显示代码？

Answer 1

我在代码中改变了一点点，现在它正在运行。我的代码是：

public function get_agent_tree_commision()
{   
    $query = $this->db->query("select * from agent where id = '1'");

    $result = $query->result();

    $roles = array();

    foreach($result as $key=>$value)
    {   

            $role = array();

            $role['id'] = $result[$key]->id;

            $role['Name'] = $result[$key]->Name;

            $children = $this->build_child($result[$key]->id);              

            if( !empty($children) ) {

                $role['children'] = $children;

            }
            $roles['role'] = $role;             

    }       

    $this->load->view("cashier/get_agent_tree_commision",$roles);
}

public function build_child($parent)
{
    $query = $this->db->query("select * from agent where Introducer_code = '$parent'");

    $result = $query->result();

    $roles = array();       

    foreach($result as $key => $val) {

        if($result[$key]->Introducer_code == $parent) {
            $role = array();

            $role['id'] = $result[$key]->id;
            $role['Name'] = $result[$key]->Name;

            $children = $this->build_child($result[$key]->id);

            if( !empty($children) ) {                   

                $role['children'] = $children;

            }
            $roles[] = $role;
        }
    }
    return $roles;

}

的变化：

1）在get_agent_tree_cummision（）函数中我改变了这一行

$children = $this->build_child($result[$key]->id);

2）在build_child（$ parent）函数中，我添加了查询

$query = $this->db->query("select * from agent where Introducer_code = '$parent'");

$result = $query->result();

3）我在build_child（$ parent）函数的foreach循环中返回$ roles。

最后，它完美无缺。

Answer 2

我转换了一个PHP类，用于执行父子关系的Codeigniter。

它位于here.

我不知道你使用哪个CI版本但是在V3的情况下你可以尝试以下内容：

在您的模型中：

<?php
class Agent_Model extends CI_Model
{

    public function loadAgent($id)
    {
        $query = $this->db
            ->select("*")
            ->from("agent")
            ->where("id",$id)
            ->get();

        $objAgent = $query->row(0, "Agent_Object");
        $this->loadChildAgents($objAgent);

        return $objAgent;
    }

    private function loadChildAgents(Agent_Object $objAgent)
    {

        $query = $this->db
            ->select("*")
            ->from("agent")
            ->where("Introducer_code",$objAgent->Introducer_code)
            ->get();

        if ($query->num_rows() > 0)
        {
            foreach($query->result() AS $objChild)
            {
                $objAgent->addChild($objChild);
            }
        }
    }
}

class Agent_Object
{
    private $arrChilds = array();


    public function addChild($objChild)
    {
        $this->arrChilds[] = $objChild;
    }

    public function getChilds()
    {
        $obj = new ArrayObject($this->arrChilds);
        return $obj->getIterator();
    }

}

并在您的控制器中

<?php

class Agent extends CI_Controller
{

    public function __construct()
    {
        $this->load->model("Agent_Model");
    }

    public function agentTree()
    {
        $objAgent = $this->Agent_Model->loadAgent(1);

        $arrViewData = array("objAgent" => $objAgent);

        $this->load->view("cashier/get_agent_tree_commision",$arrViewData);
    }
}

并在您的视图中

<?php
echo $objAgent->Name;
?>
Childs
<?php
foreach($objAgent->getChilds() AS $key => $objChild)
{
    print_r($objChild);
}
