问题描述
我已经被困在这一点上很长时间了，即使在阅读了许多帖子后，我也没有找到解决方案.
我正在制作一个测验的界面，在管理界面中，我需要将图像上传到文件夹并将图像名称上传到数据库.我可以处理其他事情，但图片上传困扰了我很长时间.
请看下面我的代码.
表格
<?php echo form_open_multipart('admin/update_question');?><?php echo form_hidden('questionid', $question->level);?><?php echo form_label('Comment', 'comment');?><div class="输入"><?php$arr_comment = 数组('名称' =>'评论'，'id' =>'评论'，'价值' =>$问题->评论);echo form_textarea($arr_comment);?>
<br/><?php echo form_label('Answer', 'answer');?><div class="输入"><?php$arr_answer = 数组('名称' =>'回答'，'id' =>'回答'，'尺寸' =>'10000','价值' =>$question->answer);echo form_input($arr_answer);?>
<br/><?php echo form_label('Image', 'userfile');?><div class="输入"><?php$arr_image = 数组('名称' =>'用户档案','id' =>'用户档案','价值' =>'');echo form_upload($arr_image);?>
<br/><?php$arr_button = 数组('名称' =>'提交'，'价值' =>'更新问题','类' =>'btn 初级大');?><div class="输入"><?php echo form_submit($arr_button);?>
<br/><?phpecho form_close();如果($错误！= '')echo '<div class="alert-message error">'.$错误.'
';回声验证错误()；?>
我试过运行一个 js，它在上传框中返回文件名，它确实返回了它.
控制器
公共函数update_question() {$comment = $this->input->post('comment');$answer = $this->input->post('answer');echo var_dump(is_dir(base_url().'uploads/'));/** 上传图片*/$config['upload_path'] = base_url().'/uploads/';$config['allowed_types'] = 'gif|jpg|png';$config['max_width'] = 0;$config['max_height'] = 0;$config['max_size'] = 0;$config['encrypt_name'] = TRUE;$this->load->library('upload', $config);如果 ( !$this->upload->do_upload()){$error = array('error' => $this->upload->display_errors());打印_r($错误)；}别的{$arr_image = array('upload_data' => $this->upload->data());打印_r($arr_image);}$questionid = $this->input->post('questionid');$question_data = 数组('评论' =>$评论，'答案' =>$答案);$this->load->model('adminmodel', 'admin');$question_data = $this->admin->update_question_data($questionid, $question_data);//重定向('管理员/问题'，'位置')；}
对于我的上传路径，我尝试了一个数字或组合，唯一一个返回 TRUE 值的是 var_dump(is_dir('/wamp/www/quark_edorado/uploads')); 但这也返回了同样的错误.
我不知道我哪里出错了.
更新
我的目录结构是
/application//上市/css/字体/图片/js//系统//上传/
我正在操作 Windows 机器并使用 WAMP.这有什么不同吗?
解决方案
当我尝试通过 $this->load->library('upload', $config); 它不会这样做.
相反，我将配置文件放在 config/upload.php
另一种方法是 $this->upload->initialize($config);
I have been stuck at this point for a long time and even after reading a number of posts, I haven't been able to find a solution.
I am making an interface for a quiz, and in the admin interface, I need to upload images to a folder and upload the image name to the database. I can handle to other things but the image upload is bugging me alot for a long time.
Please take a look at my code below.
The Form
<?php echo form_open_multipart('admin/update_question'); ?>
<?php echo form_hidden('questionid', $question->level); ?>
<?php echo form_label('Comment', 'comment'); ?>
<div class="input">
<?php
$arr_comment = array(
'name' => 'comment',
'id' => 'comment',
'value' => $question->comment
);
echo form_textarea($arr_comment);
?>
</div>
<br/>
<?php echo form_label('Answer', 'answer'); ?>
<div class="input">
<?php
$arr_answer = array(
'name' => 'answer',
'id' => 'answer',
'size' => '10000',
'value' => $question->answer
);
echo form_input($arr_answer);
?>
</div>
<br/>
<?php echo form_label('Image', 'userfile'); ?>
<div class="input">
<?php
$arr_image = array(
'name' => 'userfile',
'id' => 'userfile',
'value' => ''
);
echo form_upload($arr_image);
?>
</div>
<br/>
<?php
$arr_button = array(
'name' => 'submit',
'value' => 'Update Question',
'class' => 'btn primary large'
);
?>
<div class="input">
<?php echo form_submit($arr_button); ?>
</div>
<br/>
<?php
echo form_close();
if ($error != '')
echo '<div class="alert-message error">'. $error.' </div>';
echo validation_errors();
?>
I have tried running a js which returns the filename in the upload box, and it does return it.
The Controller
public function update_question() {
$comment = $this->input->post('comment');
$answer = $this->input->post('answer');
echo var_dump(is_dir(base_url().'uploads/'));
/*
* Uploading image
*/
$config['upload_path'] = base_url().'/uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_width'] = 0;
$config['max_height'] = 0;
$config['max_size'] = 0;
$config['encrypt_name'] = TRUE;
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
print_r($error);
}
else
{
$arr_image = array('upload_data' => $this->upload->data());
print_r($arr_image);
}
$questionid = $this->input->post('questionid');
$question_data = array(
'comment' => $comment,
'answer' => $answer
);
$this->load->model('adminmodel', 'admin');
$question_data = $this->admin->update_question_data($questionid, $question_data);
//redirect('admin/questions', 'location');
}
For my upload path, I have tried a number or combinations and the only one which returned a TRUE value was var_dump(is_dir('/wamp/www/quark_edorado/uploads')); but this also returned the same error.
I do not know where I am going wrong.
Update
My directory structure is
/application/
/public/
css/
fonts/
images/
js/
/system/
/uploads/
I am operating a Windows machine and using WAMP. Does that make a difference?
解决方案
I was autoloading the library and somehow when I was trying to initialize the configuration by $this->load->library('upload', $config); it wouldn't do so.
Instead I put my config files in config/upload.php
The other method to do so would have been $this->upload->initialize($config);
