vBulletin Conditional Validation

Template conditionals (<vb:if>, <vb:else>, <vb:elseif>, and {vb:if}) allow a lot of power within the vBulletin template system. The general philosophy here is to support a limited subset of PHP logic that is sufficient for most purposes. The default behavior is to exclude functionality unless there is a specific reason to include it. The reason is that there are a lot of complicated expressions allowed within PHP and this makes validation more difficult to validate safety in th...

AdminCP → Maintenance → Diagnostics → System Information MySQL's SHOW TABLE STATUS command helps gather information about tables in a database. When executed, it provides a detailed overview of various metrics related to each table in the database. This information can be valuable for database administrators and developers to optimize performance, troubleshoot issues, and better understand their databases' structure. Let's delve into the output of MySQL's SHOW TABLE STATUS command and underst...

vBulletin allows the upload of file attachments. Servers and browsers generally recognize the type of file using two methods; file extensions and MIME types. This document is to allow you to match extensions with MIME types so they are properly handled by browsers. table {width: 80%; margin-left:auto; margin-right:auto} table td:first-child { text-align:center} tr:nth-child(even) {background: #CCC} tr:nth-child(odd) {background: #FFF} th{ color: white; background: black; } Media Images DefaultExtensi...

vBulletin creates a number of cookies for functional purposes in the software. These default cookies do not track the user or report to a third-party. User Data Cookies These cookies track logged in users. They last for the session unless the user selects "Remember Me" on log in. It "Remember Me" is checked, the cookies will last for at least a year and are refreshed with every visit to the site. userid: Userid of Logged in User. password: hash of the user's password. sessionhash: Tracks the curre...

Note: vBulletin Cloud sites cannot use custom password schemes at this time. The core security of your site is the User Password and how it is stored. In the beginning, vBulletin used a simple MD5 hash to represent the password. However as Floating Point Processors (i.e. GPU and ASICs) have become more powerful, this method proved to be risky and reduced security. If we significantly changed the password scheme, then users wouldn't be able to login and would need to change their passwor...
