不按顺序排序

我试图按日期排序并显示结果，但更改asc或desc对视图中的顺序外观没有影响。不按顺序排序

型号：

function DisplayLatest() 
    { 
    $query = $this->db->query("SELECT * FROM CIUploads INNER JOIN CIUsers ON CIUploads.UserID = CIUsers.UserID"); 
    $this->db->order_by("UploadLikes","asc"); 
    return $query->result(); 
    }

控制器：

function index() 
{ 
    $this->load->view('../templates/header.php'); 
    $this->load->model('Category_model'); 
    $data['allwork'] = $this->Category_model->DisplayLatest(); 
    $this->load->view('Latest_view', $data); 
    $this->load->view('../templates/footer.php'); 
}

查看：

 foreach ($allwork as $value) //joined display// 
     { 
      echo "<div class='col-lg-4 display-item'>"; 
       echo "<a href='BLANK'' class='display-link'>"; 
        echo "<div class='caption'>"; 
         echo "<div class='caption-content'>"; 
          echo "<i class='fa fa-eye fa-3x'></i>"; 
         echo "</div>"; 
        echo "</div>"; 
        echo "<img src='".base_url("/application/uploads/")."/".$value->UploadedAt."' class='img-responsive'>"; 
       echo "</a>"; 
       echo "<div class='showcase-information'>"; 
        echo "<p class='caption'>&quot;".$value->UploadTitle."&quot;</p>"; 
        echo "<p class='stats'><i class='fa fa-eye'></i>".$value->UploadViews." <i class='fa fa-heart'></i>".$value->UploadLikes." <i class='fa fa-comments'></i>".$value->UploadComments." </p>"; 
       echo "</div>"; 

       echo "<a href='BLANK'><div class='showcase-user'>"; 
        echo "<p>".$value->Username."<img src=".$value->ProfileImg." class='img-circle'></p>"; 
       echo "</a>"; 

         echo "</div>"; 
        echo "</div>"; 

}

（我通过上传意识到IM排序喜欢，因为这是一个整数，应该工作）

为什么不你在$ query变量放在ORDER BY子句？ –

试试这个

function DisplayLatest() 
    { 
    $query = $this->db->select("*")->from("CIUploads")->join("CIUsers","CIUploads.UserID = CIUsers.UserID","inner")->order_by("CIUploads.UploadLikes","asc")->get(); 
    return $query->result(); 
    }

为了提高答案的质量，请解释它。 –

当您使用$this->db->query()时，这不是正确的写查询方式。

试试这个，这应该工作

$query = $this->db->query("SELECT * FROM CIUploads INNER 
JOIN CIUsers ON CIUploads.UserID = CIUsers.UserID ORDER BY UploadLikes asc");

$this->db->query()将直接执行查询。它不会检查下一行。

笨查询生成器类/活动记录

http://www.codeigniter.com/user_guide/database/query_builder.html

型号功能

public function display_latest() { 
    $this->db->select('*');  
    $this->db->from($this->db->dbprefix . 'CIUploads'); 
    $this->db->join($this->db->dbprefix . 'CIUsers', 'CIUsers.UserID = CIUploads.UserID'); 
    $this->db->order_by("CIUploads.UploadLikes","ASC"); 
    $query = $this->db->get(); 

    if ($query->num_rows() > 0) { 

     return $query->results(); 
     // return $query->results_array 

    } else { 

     return FALSE; 

    } 

}

我不认为它是在具有大写所有的时间用于功能display_latest()

好的做法

在控制器上调用模型时，在codeigniter上，您不需要

文件名如：Some_name.php

<?php 

class Some_name extends CI_Controller { 

public function __construct() { 
    parent::__construct(); 
    // You do not need the upper case letter here 
    $this->load->model('category_model'); 
} 

function index() { 
    /* 

     If view is stored in views folder you do not need to use.php 
     $this->load->view('templates/header.php'); 

    */ 

    $this->load->view('templates/header'); 

    $data['allwork'] = $this->category_model->display_latest(); 

    /* 

    Not sure why you have upper case for view you do not need to on view files 

    Only Controllers/Models/libraries file names and class names have first letter upper case. 

    */ 

    $this->load->view('latest_view', $data); 

    $this->load->view('templates/footer'); 
} 

}
