我试图获取文件路径,以便我可以在windows azure blob容器中上传。
public function upload_container()
{
$blobRestProxy = ServicesBuilder::getInstance()->createBlobService($connectionString);
$this -> load -> helper('form');
$this -> load -> helper('url');
$result=$this-> input ->post('file');
$result1=$_FILES['file']['tmp_name'];
if($result != NULL)
{
$content = fopen($result1, "r");;
$blob_name = "myblob3.jpg";
try {
$blobRestProxy->createBlockBlob("mycontainer", $blob_name, $content);
$data['blob_error']="check Azure Container";
$this->load->view('blob',$data);
}
catch(ServiceException $e){
$code = $e->getCode();
$error_message = $e->getMessage();
echo $code.": ".$error_message."<br />";
}
}else{
$this -> load -> helper('form');
$this-> load -> view('blob');
}
}
我的观点:
<?php
echo form_open('blob/upload_container');
?>
Select a file:
<input type="file" name="file" id="file">
<input type="submit" value="Upload Image" name="submit">
<?php if(isset($blob_error)){echo $blob_error;} ?>
</form>
错误: Error Page 这是我的代码,我使用codeigniter。当我在print_r中使用var-dump和NULL时,$ _FILES返回array(0){}。
如果我无法获取文件路径,则无法上传文件。那么我该如何解决呢?

为了从表单获取上传文件,您可以在视图文件中使用form_open_multipart()
函数。
请尝试修改您的视图文件:
<?php
echo form_open_multipart('text/upload_container');
?>
Select a file:
<input type="file" name="file" id="file">
<input type="submit" value="Upload Image" name="submit">
<?php if (isset($blob_error)) {echo $blob_error;}?>
</form>
然后在您的控制器文件中:
$connectionString = "<connectionString>";
$blobRestProxy = ServicesBuilder::getInstance()->createBlobService($connectionString);
$this -> load -> helper('form');
$this -> load -> helper('url');
$result1=$_FILES['file']['tmp_name'];
if($result1 != NULL)
{
$content = fopen($result1, "r");
$blob_name = "myblob3.jpg";
try {
$blobRestProxy->createBlockBlob("mycontainer", $blob_name, $content);
$data['blob_error']="check Azure Container";
$this->load->view('blob',$data);
}
catch(ServiceException $e){
$code = $e->getCode();
$error_message = $e->getMessage();
echo $code.": ".$error_message."<br />";
}
}else{
$this -> load -> helper('form');
$this-> load -> view('blob');
}
