Codeigniter: Upload/Save Image to Database
提问by Jeffrey Teruel
I'm trying to create a user profile edit form on a Codeigniter project with the ability to upload a profile image. I'd like allow the upload to go through when the user clicks the submit button. I have no problems with the form (no errors), but I do not see any image on the uploads folder I set up. Any help to get the upload working would be greatly appreciated.
我正在尝试在 Codeigniter 项目上创建一个用户个人资料编辑表单，并能够上传个人资料图片。我希望在用户单击提交按钮时允许上传。我的表单没有问题（没有错误），但我在我设置的上传文件夹中没有看到任何图像。任何帮助上传工作将不胜感激。

You should include enctype in form
您应该在表单中包含 enctype
enctype="multipart/form-data"
<form id="edit_form" class="form-horizontal" method="post" action="<?php echo base_url() . "users/update_edit/" . $user->user_id; ?>" enctype="multipart/form-data">

Can you try this code after library is being loaded.
您可以在加载库后尝试此代码。
$this->upload->initialize($config);
if (!$this->upload->do_upload('profile_img_path')) {
$error = array('error' => $this->upload->display_errors());
echo $error['error'];
}
Let us know what exact error you are getting.

$config['upload_path'] = '/uploads/profilepics';points to a folder in the filesystem, which you probably have no write access to. Use a relative path like $config['upload_path'] = './uploads/profilepics';(./being the current directory). Also make sure the folder(s) exist and you have write access to it.
$config['upload_path'] = '/uploads/profilepics';指向文件系统中的一个文件夹，您可能没有写入权限。使用相对路径，如$config['upload_path'] = './uploads/profilepics';（./即当前目录）。还要确保文件夹存在并且您对其具有写入权限。
