502 Bad Gateway on Raspberry Pi Running OpenMediaVault
This error occurs after doing an update of php5-pam. In order to fix this if this happens, do the following:
Log in via ssh as root and try:
wget http://omv-extras.org/debian/pool/main/p/php5-pam/php5-pam_1.0.3-2_armhf.deb
dpkg -i php5-pam_1.0.3-2_armhf.deb
reboot
Limiting input tag to numbers without using html 5 type=”number”
The reason for this post is due to the fact that not all major browsers support HTML input types yet.
This example limits the input to numbers.
<input onkeypress=’return event.charCode >= 48 && event.charCode<=57′>
This example limits the input to numbers, but, decimal works.
<input onkeypress=’return (event.charCode >= 48 && event.charCode<=57) || event.charCode==46′ >
Adminer
I have been doing MySQL database administration and applications for a long time now and I can’t believe that I’ve never heard of Adminer before.
Adminer is a PHP database manager. As near as I can tell, it contains all of the same functionality of phpMyAdmin, but, seems to be quicker.
I recently came across this and have been using it exclusively ever since. Prior to this, I have always just used phpMyAdmin.
If you have not yet tried to use this single page database manager, I strongly recommend giving it a try.
Checking WordPress User Capabilities
Recently I spent some time trying to determine user capabilities while developing some plugins. I figured I’d put what I learned here for future reference.
In order to check a current user’s capabilities (i.e. are they an admin?) use the function;
current_user_can( capability )
An example would be:
if (current_user_can(‘manage_options’)) {
// User is an administrator.
/* Do something */
}
If you want to check a particular user, use the function;
user_can(id, capability).
This works exactly like the previous example, however, it takes an ID as a paramter.
An example would be:
if (user_can($id, ‘manage_options’)){
// User is an administrator
/* Do something
}
For a complete list of roles and capabilities, please reference this site.
Database Plugin for MySQL
I am working on a new plugin for WordPress which is intended to give you capabilities similar to those in phpMyEdit. I have been waiting for a while for someone to design a table editor for MySQL that plugs in to WordPress. Turns out, that someone is going to be me.
As soon as I have something tangible, I will post it so that others can play with it.

There really isn’t anything of interest on here yet. Just a place to play around with some of my stuff. Thanks for stopping by, though.
