使用多个输入字段上传多个文件
我认为有几个输入字段是这样的
<head>
<title>Upload Form</title>
</head>
<body>
<?php echo form_open_multipart('info/normal_upload');?>
<input type="file" name="one" size="20" />
<input type="file" name="two" size="30" />
<input type="file" name="three" size="40" />
<br /><br />
<input type="submit" value="upload" />
</form>
</body>
</html>
我正在像这样上传文件
$config['upload_path'] = realpath(FCPATH.'uploads');
$config['allowed_types']= "gif|jpg|png|jpeg|pdf";
$config['overwrite'] = TRUE;
$config['max_size'] = "2048000";
$config['max_height'] = "5000";
$config['max_width'] = "5000";
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('one'))
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('normal_upload', $error);
}
if ( ! $this->upload->do_upload('two'))
{
$error = array('error' => $this->upload->display_errors());
//$this->load->view('normal_upload', $error);
}
if ( ! $this->upload->do_upload('three'))
{
$error = array('error' => $this->upload->display_errors());
//$this->load->view('normal_upload', $error);
}
else
{
$data = array('upload_data' => $this->upload->data());
echo $data['upload_data']['full_path'].'<br/>';
//$this->load->view('normal_upload', $data);
}
我想获取所有上传文件的文件名、路径。如果我在所有表单字段中选择文件，文件将被上传，但是：
echo $data['upload_data']['full_path'].'<br/>';
只能获取一个文件路径。如何获取文件路径并重命名上传的文件？

使用 $this->load->library('upload', $config); 加载库；当您只上传一个文件时有效。但是，当您上传多个文件时，您需要使用配置重新初始化库。就像这样：$this->load->library('upload');$this->upload->initialize($config);if ( ! $this->upload->do_upload('one')){ $error = array('error' => $this->upload->display_errors()); $this->load->view('normal_upload', $error);}$data['one'] = array('upload_data' => $this->upload->data());$this->upload->initialize($config); if ( ! $this->upload->do_upload('two')){ $error = array('error' => $this->upload->display_errors()); //$this->load->view('normal_upload', $error);} $data['two'] = array('upload_data' => $this->upload->data()); $this->upload->initialize($config); if ( ! $this->upload->do_upload('three')){ $error = array('error' => $this->upload->display_errors()); //$this->load->view('normal_upload', $error);}$data['three'] = array('upload_data' => $this->upload->data());然后您可以使用以下命令访问文件数据：$data['one']['upload_data']['full_path'];$data['two']['upload_data']['full_path'];$data['three']['upload_data']['full_path']; -

事实证明它并不是那么简单。下面的代码：仅上传图像文件和 pdf，仅允许上传图像和 pdf重命名上传的文件删除上传文件中的所有空格public function normal_upload(){ $uploadLocation = "uploads/"; $uploadMainTo = null; if(isset($_FILES['MainImage'])){ $path = $_FILES['MainImage']['name']; // file means your input type file name $ext = pathinfo($path, PATHINFO_EXTENSION); if ($ext=="jpg" OR $ext=="jpeg" OR $ext=="gif" OR $ext=="png" OR $ext=="pdf") { echo "Upload successful"; }else{ // your invalid code here like... echo "Invalid image format. Only upload JPG or JPEG or GIF or PNG"; header('Location: http://localhost/upload_app/info/nu'); exit; } $main_image_name = $_FILES['MainImage']['name']; $main_image_size = $_FILES['MainImage']['size']; $main_image_tmp = $_FILES['MainImage']['tmp_name']; $uploadMainTo = $uploadLocation.sa(time().mt_rand(43,672882).bin2hex(random_bytes(16)).trim($main_image_name)); $moveMain = move_uploaded_file($main_image_tmp,$uploadMainTo); echo $uploadMainTo.'<br/>'; } $uploadSecondTo = null; if(isset($_FILES['SecondImage'])){ $path = $_FILES['SecondImage']['name']; // file means your input type file name $ext = pathinfo($path, PATHINFO_EXTENSION); if ($ext=="jpg" OR $ext=="jpeg" OR $ext=="gif" OR $ext=="png" OR $ext=="pdf") { // your code here like... echo "Upload successful"; }else{ // your invalid code here like... echo "Invalid image format. Only upload JPG or JPEG or GIF or PNG"; header('Location: http://localhost/upload_app/info/nu'); exit; } $second_image_name = $_FILES['SecondImage']['name']; $second_image_size = $_FILES['SecondImage']['size']; $second_image_tmp = $_FILES['SecondImage']['tmp_name']; $uploadMainTo = $uploadLocation.sa(time().mt_rand(43,672882).bin2hex(random_bytes(16)).trim($main_image_name)); $moveSecond = move_uploaded_file($second_image_tmp,$uploadSecondTo); echo $uploadSecondTo.'<br/>'; } $uploadPdfTo = null; if(isset($_FILES['PDF'])){ $path = $_FILES['PDF']['name']; // file means your input type file name $ext = pathinfo($path, PATHINFO_EXTENSION); if ($ext=="jpg" OR $ext=="jpeg" OR $ext=="gif" OR $ext=="png" OR $ext=="pdf") { // your code here like... echo "Upload successful"; }else{ // your invalid code here like... echo "Invalid image format.
