Edit php.ini on heroku

Question

I've put wordpress up on Heroku and have a 2.5MB custom theme I need to upload.

I've installed the wpro plugin to send my uploads directly to s3, however, I still get the error. I think i still need to edit the php.ini file, specifically these lines:

; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 2M

I need to change that to 3M.

How can I edit the php.ini file??

Answer 1

I got this to work by making wordpress-heroku read a custom php.ini.

I copied the heroku buildpack's php.ini into my root directory https://github.com/heroku/heroku-buildpack-php/blob/master/conf/php/php.ini

I renamed it to custom_php.ini and changed the following lines

upload_max_filesize = 3M
post_max_size = 3M

I then added a Procfile with the line

web: vendor/bin/heroku-php-apache2 -i custom_php.ini .

Heroku only unofficially supports php. I contact support and they're not going to change this for me. Ultimately I think it's more trouble than it's worth because Heroku isn't intended to be a file writing system - anything you change will be undone unless the change is made on your local system and committed in git. Even if you set up WPRO and ship all your static to Amazon s3, you'll run into trouble.

It was much easier for me to set Wordpress up on Amazon E2.
