我对codeigniter仍然很陌生。我遇到的问题是,文件上传正常,它写入数据库没有问题,但它只是不会返回到上传表单。相反,它保留在do_upload中,不显示任何内容。更奇怪的是,幕后出现了一些源代码,这些源代码似乎是当您不选择要上传的图像时出现的消息。有人可以告诉我什么是我做错了,因为我想提交后返回到我的上传表单。提前致谢。下面是我的代码:Codeigniter在图像上传后没有返回上传表单
控制器:
function do_upload()
{
if(($error = $this->Upload_model->do_upload()) === true)
{
$this->load->view('home/upload_form');
}else{
$this->load->view('home/upload_success', $error);
}
}
型号:
function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '2000';
$this->load->library('upload', $config);
if (! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
return $error;
}
else
{
$data = $this->upload->data();
$full_path = 'uploads/' . $data['file_name'];
$spam = array(
'image_url' => $full_path,
'url' => $this->input->post('url')
);
$id = $this->input->post('id');
$this->db->where('id', $id);
$this->db->update('NavItemData', $spam);
return true;
}
}
视图(称为upload_form):
<html>
<head>
<title>Upload Form</title>
</head>
<body>
<?php if(isset($buttons)) : foreach($buttons as $row) : ?>
<h2><?php echo $row->image_url; ?></h2>
<p><?php echo $row->url; ?></p>
<p><?php echo $row->name; ?></p>
<p><?php echo anchor("upload/update_nav/$row->id", 'edit'); ?></p>
<?php endforeach; ?>
<?php endif; ?>
</body>
</html>
下面是实际的上传表单:
<html>
<head>
<title>Upload Form</title>
</head>
<body>
<?php echo form_open_multipart('upload/do_upload');?>
<?php if(isset($buttons)) : foreach($buttons as $row) : ?>
<h2><?php echo $row->name; ?></h2>
<input type="file" name="userfile" size="20" />
<input type="hidden" name="oldfile" value="<?php echo $row->image_url; ?>" />
<input type="hidden" name="id" value="<?php echo $row->id; ?>" />
<br /><br />
<label>Url: </label><input type="text" name="url" value="<?php echo $row->url; ?>" /><br /><br />
<input type="submit" value="submit" />
</form>
<?php endforeach; ?>
<?php endif; ?>
</body>
</html>
