increase max upload limit in wordpress

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

I tried different way like attempted to

1. change my limit directly on my server
2. through the .htaccess file
3. 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

1. create a php.ini
2. 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

Answer 2

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

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 4

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.

Answer 5

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/

Answer 6

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.
