IIS 7 PHP Write Permissions

by

Problem:

PHP is throwing errors saying it cannot find a directory when trying to upload a file.  This usually means PHP does not have permissions to create or modify files in that directory.

Solution:

I’m not sure why, but adding Modify and Write permissions for COMPUTERUsers group solves the problem.  Found the solution here: http://forums.iis.net/t/1153990.aspx

WordPress CMS Plugins

by

WordPress has tons of features, but most clients just need to edit pages and want a content management system.  I needed to get rid of all the fat.

Complicated Menus

To get rid of the menus on the dashboard for all roles except the admin place the following code in the functions.php of your theme.

function remove_menus () {
    global $menu;
    if (!(current_user_can('install_themes'))) {
        $restricted = array(__('Dashboard'), __('Posts'), __('Media'), __('Links'), __('Pages'), __('Appearance'), __('Tools'), __('Users'), __('Settings'), __('Comments'), __('Plugins'));
    }
    else {
        return;
    }
	end ($menu);
	while (prev($menu)){
		$value = explode(' ',$menu[key($menu)][0]);
		if(in_array($value[0] != NULL?$value[0]:"" , $restricted)){unset($menu[key($menu)]);}
	}
}
add_action('admin_menu', 'remove_menus');

Redirected Login

A problem that arises from this is the dashboard is pretty much useless.  You can use this plugin to redirect a user to a specific page based on their role:  http://wordpress.org/extend/plugins/peters-login-redirect/

Easy TinyMCE adjustments

One plugin that makes this very simple:  http://wordpress.org/extend/plugins/tinymce-advanced/

 

Use the Same Arg in Sprintf

by

When using sprintf you can use the same argument  like so:

sprintf(“You want the %1$s? You can’t handle the %1$s!”, “truth”);

The %1$s means it will pull from the first argument.

Creating an Instance of a PHP Class

by

Problem:

This works in PHP 5.3+:

$CLASS_NAME = 'TheName';

$class_instance = new $CLASS_NAME;

This doesn’t

define('CLASS_NAME', 'TheName');

$class_instance = new CLASS_NAME;

 

Workaround:

Use the way that works.  There are other limitations with using a variable to create a class.  Another way to create a class from a variable is by using:

$test = call_user_func(array($className, 'getInstance'));
