warning The PHP temporary folder is not set

[blondie63]

Hi, i've many sites with JM3 and now some new JM4 sites in hosting on servers managed by Runcloud.io
All JM4 works fine but i've this warning:
"The PHP temporary folder is not set."

On jm/server settings/Path to Temp Folder i've an existing path and on runcloud webapp settings i've included this path on open_basedir, anyway the warning still here !

Is it a Joomla 4 bug ?

No
You have to access at your php.ini file and configure temporary folder:

upload_tmp_dir = (an existing folder tmp on your site)

Beware: delete the ";" at the head of the line

Just ignore it,its a warning only.

[Per Yngve Berg]

Using open_basedir, is old school. Not recommended any more. Use User folder permissions instead.

If it works don't fix it. When the php tmp file is not set in the master php.ini file then the path for tmp defaults to /tmp. Joomla already has a /tmp folder so (providing the rest of the server is configured correctly) your site should work as expected.

ok, my question is "why joomla this false warning" ?

[Olympe30]

It is not a false warning.
Just a warning is not a fatal error and may be forgotten.
Else, do that I've written.

[Webdongle]

Not a false warning. It just warns that the tmp folder is not defined in the master php.ini file. If your site is working I recommend not messing as the php default value works (even though the notification does not state that).

Easiest solution is:

Open root public_html

Click folder "administrator"

add file and name it php.ini

add code:
upload_tmp_dir = //home/put your directory name here/public_html/tmp/


Save

Problem solved

Some people will not have a php.ini file, you can also edit .htaccess file but adding above is simple enough!

i cannot user php.ini on my hosting but i've to use a file named .user.ini with same parameters
i've just code upload_tmp_dir = //home/put your directory name

but joomla 4 show this warning the same..
joomla 3 does'nt have this warning

anyway, is not so important

[Per Yngve Berg]

A path does not start with double slash in Linux.

[Webdongle]

If it not in the master php.ini file them the command will not be executed will it.
Besides which, defining the path is for when default path /tmp does not relate to the sites /tmp folder.
I repeat if it works don't fix it. The not set warning is just that 'Not set'. It does not check to see if the default path works or not.
