Increase upload file size limit for WordPress and NGNIX

There are various ways to do, but the workable way is, updating .htaccess in WordPress and NGNIX configuration file.

Issue

First, tried the way by changing function.php in theme, but no luck. Then updated .htaccess file, it worked.

Then the client gets the error “Request Entity Too Large” (413). This error reported by NGINX.

WordPress

Add following lines in .htaccess file in html directory

php_value upload_max_filesize 64M
php_value post_max_size 64M
php_value max_execution_time 300
php_value max_input_time 300

Then the upload page in WordPress should be shown as below

Maximum upload file size: 64 MB.

Alternative

These options are PHP options, which can be applied to php.ini as well as below

upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300

NGINX

Add the following line to http, server or location context in nginx.conf or conf.d/default.conf

client_max_body_size 64M;

Then reload NGINX configure.

# /usr/local/nginx/sbin/nginx -s reload

This will fix the client error “Request Entity Too Large” (413).
