未定义的索引...现有索引? [英] Undefined Index for ... existing index?

问题描述

好，那不只是奇怪的了...

OK, that's more than weird...

这是我的代码:

public function results($id,$pattern=3)
{
    $this->load->library('session');

    if (!$this->session->userdata('logged_in'))
    {
        $this->session->set_flashdata('return_url',$this->uri->uri_string());
        redirect('log/in','refresh');
    }
    else
    {
        $this->load->model('projects');

        $proj = (array)$this->projects->getProjectById($id);

        print_r($proj);

        $progressPercentage = number_format((float)( ($proj['progress'] * 100) / $proj['total'] ), 2, '.', '');

    }
}

现在，这是问题所在:

• 将NO $pattern传递给控制器​​时，整个程序运行正常.

• 当我传递诸如mysite.com/project/results/45/4(pattern = 4)之类的参数时，出现以下错误:

• When NO $pattern is passed to the controller, the whole thing works fine.

• When I pass some parameter, like mysite.com/project/results/45/4 (pattern=4), I'm getting the following error :

A PHP Error was encountered

Severity: Notice

Message: Undefined index: progress

Filename: controllers/project.php

Line Number: 75

奇怪的是，$id和$pattern都可以读取".

The weird thing is that both $id and $pattern are "read" fine.

当我在有关undefined index的行之前print_r ing $proj时，我得到的结果是:

When I'm print_ring $proj just before the line concerning undefined index this the results I'm getting :

Array([id] => 21240 [email] => [e-mail] [url] => somewebsite.com [domains] => another_domain [progress] => 198 [total] => 199 [别名] =>测试项目3 [状态] =>完成

Array ( [id] => 21240 [email] => [e-mail] [url] => somewebsite.com [domains] => another_domain [progress] => 198 [total] => 199 [alias] => Test Project #3 [status] => complete )

正如您可以清楚地看到的那样，progress索引非常合适.

And well as you can obviously see for yourself, the progress index is perfectly there.

那么，问题可能出在哪里呢?那是任何奇怪的CI错误吗?

So, what could the issue be? Is that any weird know CI bug?

这是var_dump($proj,$proj['progress']);给出的:

array(8) {
  ["id"]=>
  string(5) "21240"
  ["email"]=>
  string(20) "[e-mail]"
  ["url"]=>
  string(27) "somewebsite.com"
  ["domains"]=>
  string(84) "another_domain"
  ["progress"]=>
  string(3) "198"
  ["total"]=>
  string(3) "199"
  ["alias"]=>
  string(15) "Test Project #3"
  ["status"]=>
  string(8) "complete"
}
string(3) "198"

推荐答案

应为:

mysite.com/CONTROLLER/results/45/4
