代码点击器文件上传 [英] Code Igniter File upload

问题描述

我要从两个独立的视图上传图片，因此在自动加载库下，我已经包括上传。

.php在配置。从这里我传递像大小，文件类型等参数。

  if（??）{
 $ config [ 'upload_path'] = realpath（'x'）; 
 $ config ['allowed_types'] ='gif'; 
 $ config ['max_size'] ='1048'; 
 $ config ['max_width'] ='1024'; 
 $ config ['max_height'] ='768'; 
} 
 else {
 $ config ['upload_path'] = realpath（'x'）; 
 $ config ['allowed_types'] ='gif'; 
 $ config ['max_size'] ='1048'; 
 $ config ['max_width'] ='1024'; 
 $ config ['max_height'] ='768'; 
 
 
} 
  

现在有两个地方上传，我有不同的文件大小，类型参数，我的控制器如何知道要采取哪一个。如果{} else {]条件，我应该放什么。

让我知道，如果我不清楚。

解决方案

您的代码必须执行以下操作：

（1）您需要设置一个标志是一个很好的方式）在每个上传表单，让你
知道哪个文件夹存储文件。让我们调用此标志 upload_target

在你的控制器中：

（2）从post变量中获取 upload_target / p>

（3）根据值 upload_target ，根据需要设置upload_config值
，然后加载/

upload_config 值在何处放置

如果您尝试在config / upload.php中定义一个二维数组，则库加载器可能会混淆。

而是定义一个名为 upload_settings.php 的配置文件并定义以下数组：

  $ config ['target1'] ['upload_path'] ='./uploads_path_1/'; 
 $ config ['target1'] ['allowed_types'] ='gif | jpg | png'; 
 $ config ['target1'] ['max_size'] ='100'; 
 $ config ['target1'] ['max_width'] ='1024'; 
 $ config ['target1'] ['max_height'] ='768'; 
 
 $ config ['target2'] ['upload_path'] ='./uploads_path_2/'; 
 $ config ['target2'] ['allowed_types'] ='gif | jpg | png'; 
 $ config ['target2'] ['max_size'] ='100'; 
 $ config ['target2'] ['max_width'] ='1024'; 
 $ config ['target2'] ['max_height'] ='768'; 
  

在上传控制器中，您将执行以下操作：

  $ this-> config-> load（'upload_settings'，TRUE）; 
  

根据 upload_target 的值，从表单的post变量获取：

  $ upload_config_values = $ this-> load-> config（'target1' upload_settings'）; 
  

或

  $ upload_config_values = $ this-> load-> config（'target2'，'upload_settings'）; 
  

您现在可以载入或初始化上传类别：

  $ this-> load-> library（'upload'，$ upload_config_values）; 
  

我把它写成元代码给你一个可行的方法。 >

设置隐藏值标志/参数

对于您用于上传文件的每个表单，请添加一个隐藏值

对于第一种形式：

从post变量获取 upload_target 并根据该值选择正确的配置文件。

I am uploading images from two separate views so in autoload under libraries, I have included upload.

I have a file called upload.php in config. From this I am passing parameters like size,file type etc.

          if( ??){
        $config['upload_path'] = realpath('x');
$config['allowed_types'] = 'gif';
$config['max_size'] = '1048';
$config['max_width']  = '1024';
$config['max_height']  = '768';
          }
           else{
        $config['upload_path'] = realpath('x');
$config['allowed_types'] = 'gif';
$config['max_size'] = '1048';
$config['max_width']  = '1024';
$config['max_height']  = '768';


              }

Now since there are two places where I upload, I have a different file size, type parameters, How do my controller know which one to take. What should I put in if{} else {] condition.

Let me know, If I am not not clear.

解决方案

Your code has to do a few things:

(1) You need to set a flag (hidden variable is a good way) in each upload form so that you know which folder to store the file in. Let's call this flag upload_target

In your controller:

(2) Get upload_target from the post variables

(3) Depending on the value upload_target, set the upload_config values as needed and then load/initialize the upload class.

Where to put the upload_config values
If you try to define a 2-dimensional array in config/upload.php, the library loader will probably get confused.

Instead, define a config file called upload_settings.php and define the following arrays:

$config['target1']['upload_path'] = './uploads_path_1/';
$config['target1']['allowed_types'] = 'gif|jpg|png';
$config['target1']['max_size']  = '100';
$config['target1']['max_width']  = '1024';
$config['target1']['max_height']  = '768';

$config['target2']['upload_path'] = './uploads_path_2/';
$config['target2']['allowed_types'] = 'gif|jpg|png';
$config['target2']['max_size']  = '100';
$config['target2']['max_width']  = '1024';
$config['target2']['max_height']  = '768';

In your upload controller, you will do something like:

$this->config->load('upload_settings', TRUE); 

Depending on the value of upload_target that you got from the form's post variable:

$upload_config_values = $this->load->config('target1','upload_settings'); 

or

$upload_config_values = $this->load->config('target2','upload_settings');

You can now load or initialize your upload class:

$this->load->library('upload', $upload_config_values);

I wrote this up as meta-code to give you an outline of a feasible approach.

Setting Up the Hidden Value Flag/Parameter
For each form that you are using to upload files, add a hidden value as follows.
For the first form:

and for the second form:

Get the upload_target value from post variables and pick the correct configuration file based on the value.
