HowTO increase the attachment file size limit in webmail and other PHP apps

Problem: When I upload a file attachment I keep getting the following error:

Max file size of 2097152 bytes exceeded...

Solution: By default PHP limits the file size a user can post via a php form and upload via a php form.  To increase the file size limit you need to login as root and edit your /etc/php.ini file to increase the default values of the following lines and restart httpd.  Here are my recommended changes to increase the limit to 10M and then increase the servers ability to handle the larger attachment size without timeouts or memory errors:

Download the following rpm available from Charlie Brady's contrib ftp site:

ftp://ftp.e-smith.org/pub/e-smith/contrib/CharlieBrady/RPMS/noarch/e-smith-php-1.5.0-03.noarch.rpm

Install the rpm:

rpm -Uvh e-smith-php-1.5.0-03.noarch.rpm

Add these settings into the configuration database to increase the maximum attachment size to 25MB:

/sbin/e-smith/config setprop php MaxExecutionTime 1800
/sbin/e-smith/config setprop php MemoryLimit 100M
/sbin/e-smith/config setprop php PostMaxSize 25M
/sbin/e-smith/config setprop php UploadMaxFilesize 25M

Expand the template:

/etc/e-smith/events/actions/conf-php

Then restart httpd:

/etc/rc.d/init.d/httpd-e-smith graceful
