I want to use PHP and HTML on Wordpress to display the image on the confirmation screen after POSTing the form.

I would like to upload the image from the form on the front page using PHP and HTML on Wordpress, and display the image on the confirmation screen on the fixed page after POST transmission.

Using the following site as a reference, I wrote php on the page after the transition, but the upload failed.
I think the relative path in Wordpress is incorrect, but I don't know how to write it.
The error is

Warning: move_uploaded_le (./img/20210217_1728.png): failed to open stream:
No such or directory in ~ /~ /page.php.online58

will be

Upload image file 1 (HTML+PHP only)

$up_file="img/".date("Ymd_His.").mt_land(1000,9999).".$ext";
"img/" portion of the

I would appreciate it if you could let me know if anyone understands.
