我正在使用codeigniter 3,在You did not select a file to upload.
函数中收到类似do_upload()
的错误,但正常的php函数move_uploaded_file()
正常工作。我提到了stackoverflow的大多数答案,但我没有得到解决方案。
我认为它可能出现在wamp
问题中,但我没有清楚地知道它在哪里。
如果这个代码在你的机器上工作,那么它将在我的wamp php或Apache设置中出现。
查看:(upload.php)
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>
<body>
<?php echo form_open_multipart('welcome/do_upload'); ?>
<input id="sfile" type="file" name="file">
<input type="submit" value="Submit">
<?php echo form_close(); ?>
</body>
</html>
控制器:(welcome.php)
function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload()) //not working
{
$error = array('error' => $this->upload->display_errors());
var_dump($error);
}
else
{
$data = array('upload_data' => $this->upload->data());
}
echo $basename = $_FILES['file']['name'];
move_uploaded_file($_FILES['file']['tmp_name'],$config['upload_path'].$basename);
// move_uploaded_file() works fine
}

根据CI 3,您需要在$this->upload->do_upload('')
中传递名称属性。
所以你需要在其中传递name属性
$this->upload->do_upload('file');
检查您上传的文件大小,因为您设置了$ config['max_size'] = '100';
。这意味着你无法上传文件大小超过100 kb

首先加载上传库,然后初始化配置数据。
并在$ this-&gt; upload-&gt; do_upload('file')中传递输入文件类型的属性名称。
function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config); # Load upload library
$this->upload->initialize($config); # Initialize
if ( ! $this->upload->do_upload('file'))
{
$error = array('error' => $this->upload->display_errors());
var_dump($error);
}
else
{
$data = array('upload_data' => $this->upload->data());
}
}

这可能与301错误导致的职位损失有关。
尝试更换
<?php echo form_open_multipart('welcome/do_upload'); ?>
具有(解决方法)
<form action="do_upload" method="post" enctype="multipart/form-data">
如果有效,则路由配置中会出现错误
