“上传路径似乎不是有效的”。 Codeigniter文件上传不工作 [英] "The upload path does not appear to be valid". Codeigniter file upload not working
问题描述
我已经停留在这一点了很长时间，即使在阅读了一些帖子后，我还是找不到一个解决方案。
我我做一个测验的接口，在管理界面，我需要上传图像到一个文件夹，并将图像名称上传到数据库。
请看下面的代码。
表单
<？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（）;
？>
我试过运行一个js，返回上传框中的文件名，它会返回。
控制器
public function 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）;
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'）;
}
对于我的上传路径，我尝试过一些数字或组合，它返回 TRUE 的值是 var_dump（is_dir（'/ wamp / www / quark_edorado / uploads'））; 这也会返回相同的错误。
我不知道我在哪里错了。
更新< h2>
我的目录结构是
/ application /
/ public /
css /
fonts /
images /
js /
/ system /
/ uploads /
我正在操作Windows机器并使用WAMP。
找出了愚蠢的问题。
我正在自动加载库和一些如何当我试图初始化配置 $ this-> load-> library（'upload'，$ config）;
而是把我的配置文件放在 config / upload.php p>
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?
Figured out the idiotic problem.
I was autoloading the library and some how 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);
