increase max upload limit in wordpress - php

Question

I need to upload a PDF file to my wordpress site. When I go to Upload New Media, and try uploading it, it says
FileName.pdf exceeds the maximum upload size for this site.
I tried looking for my php.ini file but could not find it. I ran phpinfo() by creating a new file and then opening it in my browser and found this.
Configuration File (php.ini) Path
C:\Windows
Loaded Configuration File
C:\Program Files (x86)\Parallels\Plesk\Additional\PleskPHP5\php.ini
I placed a php.ini files with
upload_max_filesize = 512M
post_max_size = 512M
max_execution_time = 300
in wp-admin, httpdocs and everywhere I had access, nothing worked The max upload file size is just 8 MB. Please help me, My client needs to upload that file.
Note: Please don't tell me to restart server, as I can't, It is a hosted site.

Answer 1

Try with the following plugin:
<?php
/* Plugin Name: Increase Upload Limit */
add_filter( 'upload_size_limit', 'b5f_increase_upload' );
function b5f_increase_upload( $bytes )
{
return 33554432; // 32 megabytes
}
I built this code based on the following core function:
function wp_max_upload_size() {
$u_bytes = wp_convert_hr_to_bytes( ini_get( 'upload_max_filesize' ) );
$p_bytes = wp_convert_hr_to_bytes( ini_get( 'post_max_size' ) );
$bytes = apply_filters( 'upload_size_limit', min( $u_bytes, $p_bytes ), $u_bytes, $p_bytes );
return $bytes;
}
Another option is upload via FTP and use the plugin Add from Server.

What worked for me was editing the php.ini file at
/etc/php5/apache2/php.ini
and adding/editing the following options starting (~ line 786):
memory_limit = 32M
upload_max_filesize = 32M
post_max_size = 32M

Answer 3

I tried different way like attempted to
change my limit directly on my server
through the .htaccess file
wp-config.php
but none of these changes worked for me. Then I came across a post somewhere That I summarised in a blog post(find below)
All you need to do is
create a php.ini
upload to admin directory
Your Php.ini may contain following or whatever limit you need
memory_limit = 32M
upload_max_filesize = 32M
post_max_size = 32M
file_uploads = On

WHM/CPanel users Only
I have been struggling with this for a while now, I found the most simple way to solve this to login to your WHM > PHP Configuration Editor > Change (upload_max_filesize) then hit "SAVE".
This makes a change to your server's php.ini file (the simple way).

Answer 5

Seeing as you're on hosted service, try adding these to your .htaccess file as well:
php_value upload_max_filesize 512M
php_value post_max_size 512M
You won't be able to change these via ini_set();

Answer 6

This applies to cPanel users only. I'm not sure about which versions of cPanel it will work with, but it works with the version 56.0.33.
Login to cPanel > Select PHP version > Switch To PHP Options > Click the greyed out number next to upload_max_filesize > Change > Save
I believe this makes a change to the server's php.ini file.

Answer 7

I'm running WHM / cPanel on a CloudLinux based server. I tried everything. The final solution for me was adding a php.ini file to the /wp-admin/ directory with the following;
memory_limit = 128M
upload_max_filesize = 32M
post_max_size = 32M
Keep in mind I previously tried a php.ini in the document root and the web root directories and those didn't fix the max upload limitation.

You have written php.ini file properly. Just mention path of your php.ini file inside .htaccess file using suPHP_ConfigPath/home/username/public_html. Here replace username with your username mentioned in cpanel. You can refer http://www.vinaypn.com/how-to-fix-maximum-upload-size-exceeded-error-in-wordpress-running-on-shared-hosting/
