Cannot refer to uploaded files

Just done an install, tried to upload a file and refer it to a page 'file:/test/image_21.png'
but I got 404 file:/test/image_21.png error message.

This my env

Any ideas?

Re: Cannot refer to uploaded files

When you upload a file, the correct file: syntax is displayed in the filemeta handler. Normally, the relative path is sufficient. The absolute path is required only when you embed a local file attached to a page in another page.

A 404 file:/test/image_21.png message indicates that either
1. the path to the file is false
  - Please check if the file is already attached to the /test page.
  - Check if the page syntax is correct, the page tag is case sensitive.
  - Check if the image was uploaded as local file and not as global file (attached to a page / global name space)
    - test for file:image_21.png and file:/image_21.png
2. the file upload failed
  - Is the file visible in the filemeta handler? (/test/attachments -> to page -> click on the image)
  - Could you see the image after the file upload?
3. the file folder has insufficient access rights
Please check the file/perpage/ and file/folder/ folder as well the file table in the database, if the uploaded file is there.

Do you use mod_rewrite?

Re: Cannot refer to uploaded files

Hi WikiAdmin,

1. the path to the file is false --> The path is correct and has the right permission.

the file path is: file/perpage/@18@image_21.png

https://i.ibb.co/k5Trrsr/screenshot-127.jpg

https://i.ibb.co/sb5DxBs/screenshot-124.jpg

https://i.ibb.co/KyMBGMf/screenshot-128.jpg

2. the file upload failed --> Upload is succeded.

After upload a file, I got File upload successful but also File not found messages

https://i.ibb.co/q9W1XzB/screenshot-125.jpg

3. the file folder has insufficient access rights --> 'file/perpage' and 'file/global' have permission (I have tried full 777 permission)

4. check the file/perpage/ and file/folder/ folder as well the file table in the database --> There are no data in the 'file' and 'file_link' tables.

https://i.ibb.co/vDtcrTs/screenshot-126.jpg

5. Do you use mod_rewrite --> I have tried both 'subdomain' and 'subdirectory'

<VirtualHost 192.168.50.6:80>
    DocumentRoot /apps/testapp/wacko_test1/htdocs/
    ServerAlias wacko.kmb-note
    <Directory /apps/testapp/wacko_test1/htdocs/>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

and this

Alias /wacko_test1/ "/apps/webapps/wacko_test1/htdocs/"
Alias /wacko_test1 "/apps/webapps/wacko_test1/htdocs"

<Directory "/apps/webapps/wacko_test1/htdocs">
	Options Indexes FollowSymLinks
	AllowOverride All
	
	<IfVersion < 2.3 >
		Order allow,deny
		Allow from all
		Satisfy all
	</IfVersion>
	<IfVersion >= 2.3>
		Require all granted
	</IfVersion>
</Directory>

and in the .htaccess (for subdir)

<IfModule mod_rewrite.c>
	<IfModule mod_env.c>
		SetEnv HTTP_MOD_REWRITE on
	</IfModule>
	RewriteEngine on
	RewriteBase /wacko_test1/
	RewriteRule ^(index.php?.*)$ - [S=1]
    RewriteRule ^(.*)$ /wacko_test1/index.php?page=$1 [QSA,PT,L]
</IfModule>

Thanks and regards

Re: Cannot refer to uploaded files

So it uploads the file but it did not write the corresponding data in the file table.
The WackoFormatter parses then the file: link and can't find the corresponding record in the file table.
Did you upgrade or downgrade the wiki? Please check if the file table has no missing or changed fields, this can happen if you changed the version without using the installer. The SQL script probably fails to insert the file record due to DB structure discrepancies.

Please check the file table against the file table schema for your version.

Fix the DB structure discrepancies by hand or run a fresh install with the version you want use. Additionally you can turn on the debug option, so it will show you all failed SQL queries in the footer, look out for -1.

Re: Cannot refer to uploaded files

Hi WikiAdmin,

did you upgrade or downgrade the wiki?
> It's new fresh install 6.0.25.zip

I created the database

CREATE DATABASE wacko_test CHARACTER SET utf8mb4;
GRANT ALL PRIVILEGES ON wacko_test.* TO 'apps'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;

and then followed the install instruction. there is no error except upload file.

Re: Cannot refer to uploaded files

I did a local test with WackoWiki 6.0.30 and all works as expected.

If you want find the error turn debugging on (including SQL queries, see system section in Admin panel) and comment out
https://github.com/WackoWiki/w[...]page/upload.php#L309

Comment out this line and read the SQL log for errors.
```
# $this->http->redirect($this->href('filemeta', '', ['m' => 'show', 'file_id' => (int) $file['file_id']]));	
```
Admin Panel -> System -> Debug mode

enable the debug option to show all executed SQL queries and disable the query caching option

I have tried 6.0.30 too, but the installation stopped before creating tables. I think I will create another thread for this problem.

Re: Cannot refer to uploaded files

The culprit: [0.0003 sec., -1 rows] as expected

INSERT INTO wacko_file SET page_id = 18, user_id = 3,file_name = 'image_28.png', file_lang = 'en', file_description = '', file_size = 146011,picture_w = 1600,picture_h = 1030,file_ext = 'png',mime_type = 'image/png',uploaded_dt = '2022-05-04 14:52:29',modified_dt = UTC_TIMESTAMP()
        [0.0003 sec., -1 rows]

Put the query as is for example in phpMyAdmin and it will tell you what is missing or wrong. And please upgrade to 6.0.30.

Re: Cannot refer to uploaded files

Hi WikiAdmin

This is the error
```
Field 'caption' doesn't have a default value

I changed the default value
```
ALTER TABLE wacko_file CHANGE caption caption text DEFAULT NULL;	
```
and it works..... YEAAA.....

Re: Cannot refer to uploaded files

This can be, if you run with SQL Strict mode. We should fix this, so it will run out of the box with SQL strict mode.

constants.php
```
const SQL_MODE_STRICT				= 'TRADITIONAL,NO_ENGINE_SUBSTITUTION,ONLY_FULL_GROUP_BY';
const SQL_MODE_PERMISSIVE			= 'NO_ENGINE_SUBSTITUTION,NO_AUTO_CREATE_USER';	
```
config.php
```
'sql_mode_strict' => '0',	
```
Can you please provide a patch.

Re: Cannot refer to uploaded files

Thank You WikiAdmin,

I have tried

const SQL_MODE_STRICT				= 'TRADITIONAL,NO_ENGINE_SUBSTITUTION,ONLY_FULL_GROUP_BY';
const SQL_MODE_PERMISSIVE			= 'NO_ENGINE_SUBSTITUTION,NO_AUTO_CREATE_USER';

//these two parameters are default value

and config.php already set to

'sql_mode_strict' => '0',

change back

ALTER TABLE wacko_file MODIFY caption text NOT NULL;
