Fri, 10 Apr 2026 09:50:11 +0000 https://bugs.horde.org/ticket/7956 $_POST is returned empty (causes login loop) Issue: Horde does not appear to be able to parse the Gigabyte shorthand convention for upload_max_filesize and post_max_size in PHP.INI (e.g. 10G for 10 gigabytes). Symptoms: Login form stuck in loop, imp/test.php IMAP/POP login form loops on form submission, or if using auto login form based administration activities fail (e.g. submitting config setup forms reports "Invalid application." error). Diagnosis: $_POST structure is empty on submit, when forms are configured via Horde Framework methods. $_POST works in other PHP applications, and test scripts, on the same server not using the Horde Framework. Workaround: define values in php.ini in bytes rather than using (G)igabyte shorthand. Note - have not tested other shorthand conventions (M or K), potentially these may work as well to set gigabyte POST transfer sizes. Test conditions: configure php.ini with "upload_max_filesize = 8G" and "post_max_size = 10G". Environment details: Applicaiton: Horde Groupware Webmail Edition v.1.2.2 OS: Gentoo Linux, 2.6.24-gentoo-r7 PHP: v5.2.8 [error also occurs with earlier 5.2 bases as well] WWW Server: Lighttpd v1.5.0 (ssl) [error also occurs with v1.4.20) Fri, 06 Feb 2009 10:57:07 +0000 https://bugs.horde.org/ticket/7956#t52332 This has nothing to do with Horde. The $_POST array is built by PHP, Horde has no influence on that. Fri, 06 Feb 2009 11:40:37 +0000 https://bugs.horde.org/ticket/7956#t52334 > This has nothing to do with Horde.

Please note - that I was not able to replicate this error in any other PHP applications running on the same server, under the same test conditions (including the whole simpletest suite); only those forms built using the horde framework (including a test script I created for this specific issue) caused the $_PHP to be returned empty. However, could the suggested workaround be posted as an advisory note in the Install FAQ to assist other users.
