yii采用原始php文件上传方法上传文件
1. 编写view在view的index.php 代码如下：注意action是接受文件上传的action
<form action="api/uploadimg" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" /> </form>
在Controller的action方法如下：
public function actionUploadimg()
{
$isSuc = false;
$root = YiiBase::getPathOfAlias('webroot').Yii::app()->getBaseUrl();
$folder = $root.'/images/images/users/4/';
$desFilePath;
$tmpFilePath;
$this->mkDirIfNotExist($folder);
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/png")
|| ($_FILES["file"]["type"] == "image/jpg")
|| ($_FILES["file"]["type"] == "image/pjpeg")))
//&& ($_FILES["file"]["size"] < 20000))
{
if ($_FILES["file"]["error"] > 0)
{
$isSuc = false;
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";
$tmpFilePath = $_FILES["file"]["tmp_name"];
$desFilePath = $folder.$_FILES["file"]["name"];
if (file_exists($desFilePath))
{
unlink($desFilePath);
//echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($tmpFilePath, $desFilePath);
$isSuc = true;
}
}
}
else
{
echo "Invalid file";
}
}
function mkDirIfNotExist($dir)
{
if(!is_dir($dir))
{
if(!mkdir($dir, 0, true))
{
throw new Exception('create folder fail');
//return false;
}
else
{
return true;
}
}
return false; }
