CodeIgniter return尝试获取非对象的属性

我在 CodeIgniter </ code>中创建了一个应用程序,这在本地工作,现在我想要 尝试托管: hostinger </ code>。 如果你想看到,请检查
当我执行库安装时,问题是什么 我从下面的代码底部得到错误:</ p>

  public function get_admin_role_id()
$ result = intval($ this-&gt; db-&gt; get_where('ea_roles',array('slug'=&gt; DB_SLUG_ADMIN)) - &gt; row() - &gt; id);
print_r($ result);
返回$ result;
</ 代码> </ pre>

遇到PHP错误</ p>

严重性:通知</ p>

消息: 试图获取非对象的属性</ p>

文件名:models / admins_model.php </ p>

行号:372 </ p>
</ blockquote >

现在,此代码应返回admin的id角色,该角色设置为默认为 1 </ code>。 现在安装也参与创建表的结构并登录phpMyAdmin似乎数据库仍然是空的,也许这可能是导致问题的原因? 有人可以帮我理解发生了什么吗?</ p>

完整的管理模型 </ p>

I've made an application in CodeIgniter this working in locally and now I want to try in on a hosting: hostinger. If you want see, check this. Now the problem's that when the I perform the installation of the library I get the error on the bottom from the code below:

public function get_admin_role_id()
    $result = intval($this->db->get_where('ea_roles', array('slug' => DB_SLUG_ADMIN))->row()->id);
    return $result;

A PHP Error was encountered

Severity: Notice

Message: Trying to get property of non-object

Filename: models/admins_model.php

Line Number: 372

Now this code should be returned the id roles of admin that is setted to default to 1. Now the installation is also involved in creating the structure of the tables and logging in phpMyAdmin seems that the database is still empty, perhaps this could be the cause of the problem? Can someone help me understand what's going on?

Complete admin model

duanpao6163 检查公共函数delete($admin_id){thislinearray('id_roles'=>$this->get_admin_role_id()))->num_rows();

这样使用不是一个好习惯。 我们无法确保查询总是会产生依赖于数据库表的结果。 如果 $ this-&gt; db-&gt; get_where </ code>没有返回任何结果,则它无法调用 row()</ code>方法并访问字段 id </ code>, 它会引发错误。</ p>

所以总是这样做</ p>

  public function get_admin_role_id()
$ result = $ this-&gt; db-&gt; get_where('ea_roles',array('slug'=&gt; DB_SLUG_ADMIN));
if($ result-&gt; num_rows()== 0){
echo“找不到结果 !“;
$ row = $ result-&gt; row();
$ id = intval($ row-&gt; id);
</ code > </ pre>

请确保此查询有一些结果。 </ p>

  select * from ea_roles where slug ='your_slug';

</ code> </ pre>
</ div>



It is not a good practice to use like this. We cannot ensure that the query will always produce a result it depends on database table. if $this->db->get_where returns no results then it cannot invoke the row() method and access the field idso it will raise an error.

So always do like this

public function get_admin_role_id()
   $result = $this->db->get_where('ea_roles', array('slug' => DB_SLUG_ADMIN));
     echo "Result not found!";
    $row = $result->row();
    $id = intval($row->id);

Please make sure that this query have some result.

select * from ea_roles where slug='your_slug'; 

希望您尝试从 ea_roles </ strong>表中访问 id </ strong>列。 如果您只想访问ID,则无需使用所有(*)值,而是使用 id </ strong>。 然后像这样更新函数:</ p>

  public function get_admin_role_id()
$ id = 0;
$ result = $ this-&gt; db-&gt; select('id') - &gt; get_where('ea_roles',array('slug'=&gt; DB_SLUG_ADMIN));
if($ result-&gt; num_rows()&gt; 0){
$ id = intval ($ result-&gt; row() - &gt; id);
返回$ id;
</ code> </ pre>
</ div>



Hope you are trying to access the column id from the table ea_roles. If you want to access id only, no need to take all(*) the values, instead takes on id. Then update the function like this:

public function get_admin_role_id()
    $id = 0;
    $result = $this->db->select('id')->get_where('ea_roles', array('slug' => DB_SLUG_ADMIN));
    if ($result->num_rows() > 0) {
        $id = intval($result->row()->id);
    return $id;

Try the following:

public function get_admin_role_id() {
    return intval($this->db->get_where('ea_roles', array('slug' => DB_SLUG_ADMIN))->row()->id);

If this doesn't return anything then you don't have such record in the database

Be sure to have all of your database setted up correctly. execute the following SQL query within your phpmyadmin

Vue.js 2.0之全家桶系列视频课程

基于新的Vue.js 2.3版本, 目前新全的Vue.js教学视频,让你少走弯路,直达技术前沿! 1. 包含Vue.js全家桶(vue.js、vue-router、axios、vuex、vue-cli、webpack、ElementUI等) 2. 采用笔记+代码案例的形式讲解,通俗易懂






【为什么学爬虫?】 &nbsp; &nbsp; &nbsp; &nbsp;1、爬虫入手容易,但是深入较难,如何写出高效率的爬虫,如何写出灵活性高可扩展的爬虫都是一项技术活。另外在爬虫过程中,经常容易遇到被反爬虫,比如字体反爬、IP识别、验证码等,如何层层攻克难点拿到想要的数据,这门课程,你都能学到! &nbsp; &nbsp; &nbsp; &nbsp;2、如果是作为一个其他行业的开发者,比如app开发,web开发,学习爬虫能让你加强对技术的认知,能够开发出更加安全的软件和网站 【课程设计】 一个完整的爬虫程序,无论大小,总体来说可以分成三个步骤,分别是: 网络请求:模拟浏览器的行为从网上抓取数据。 数据解析:将请求下来的数据进行过滤,提取我们想要的数据。 数据存储:将提取到的数据存储到硬盘或者内存中。比如用mysql数据库或者redis等。 那么本课程也是按照这几个步骤循序渐进的进行讲解,带领学生完整的掌握每个步骤的技术。另外,因为爬虫的多样性,在爬取的过程中可能会发生被反爬、效率低下等。因此我们又增加了两个章节用来提高爬虫程序的灵活性,分别是: 爬虫进阶:包括IP代理,多线程爬虫,图形验证码识别、JS加密解密、动态网页爬虫、字体反爬识别等。 Scrapy和分布式爬虫:Scrapy框架、Scrapy-redis组件、分布式爬虫等。 通过爬虫进阶的知识点我们能应付大量的反爬网站,而Scrapy框架作为一个专业的爬虫框架,使用他可以快速提高我们编写爬虫程序的效率和速度。另外如果一台机器不能满足你的需求,我们可以用分布式爬虫让多台机器帮助你快速爬取数据。 &nbsp; 从基础爬虫到商业化应用爬虫,本套课程满足您的所有需求! 【课程服务】 专属付费社群+每周三讨论会+1v1答疑
