WordPress Administration menu example

Here is a very simple example of the three steps just described. This plugin will add a sub-level menu item under the Settings top-level menu, and when selected, that menu item will cause a very basic screen to display

In this example, the function, my_plugin_menu(), adds a new item to the Administration menu via the add_options_page function.
<?php
add_action('admin_menu', 'my_plugin_menu');

function my_plugin_menu() {
add_options_page('My Plugin Options', 'My Plugin', 'manage_options', 'my-unique-identifier', 'my_plugin_options');
}

function my_plugin_options() {
if (!current_user_can('manage_options'))  {
wp_die( __('You do not have sufficient permissions to access this page.') );
}
echo '<div class="wrap">';
echo '<p>Here is where the form would go if I actually had options.</p>';
echo '</div>';
}
?>

How to add administration menus in wordpress

This article explains how plugin authors can add administration menus.

Using Wrapper Functions

Since most sub-level menus belong under the Settings, Tools, or Appearance menus, WordPress supplies wrapper functions that make adding a sub-level menu items to those top-level menus easier. Note that the function names may not match the names seen in the admin UI as they have changed over time:

Dashboard
<?php add_dashboard_page( $page_title, $menu_title, $capability, $menu_slug, $function); ?>


Posts
<?php add_posts_page( $page_title, $menu_title, $capability, $menu_slug, $function); ?>


Media
<?php add_media_page( $page_title, $menu_title, $capability, $menu_slug, $function); ?>


Links
<?php add_links_page( $page_title, $menu_title, $capability, $menu_slug, $function); ?>


Pages
<?php add_pages_page( $page_title, $menu_title, $capability, $menu_slug, $function); ?>


Comments
<?php add_comments_page( $page_title, $menu_title, $capability, $menu_slug, $function); ?>


Appearance
<?php add_theme_page( $page_title, $menu_title, $capability, $menu_slug, $function); ?>


Plugins
<?php add_plugins_page( $page_title, $menu_title, $capability, $menu_slug, $function); ?>


Users
<?php add_users_page( $page_title, $menu_title, $capability, $menu_slug, $function); ?>


Tools
<?php add_management_page( $page_title, $menu_title, $capability, $menu_slug, $function); ?>


Settings

PHP array functions

PHP array  samples
 1) Desplaing the array in order, with out using sort functions
<?php
$array=array(1,20,5,16,7,19,3);
$cnt = count($array) - 1;
$FinalTemp = array();
for ($i = 0; $i <= $cnt; $i++) {
foreach($array as $key=>$value)
{
     if($value==max($array))
 {
  $sort[] = max($array);
  unset($array[$key]);
  }
}
}
 print_r($sort);
?>

2) In the main array, First delete one array values and then add other array values to the main array.
<?php
$array=array(5,4,5,7,3,6,4,1,8,4,5,6,2,1);
$delete=array(4,5,6);
$add=array(11,12,12,18);

foreach($array as $k=>$val)
{
if(in_array($val, $delete))
{
unset($array[$k]);
}
}
$result = array_merge((array)$array, (array)$add);
arsort($result);
print_r($result);
?>


3) array_count_values — Counts all the values of an array

<?php
$arr=array(a,c,k,n,n,h,r,a,a,a,c,h,b,h,k,n);
print_r(array_count_values($arr));

?>

Back to Top Scroll Up

The following Javascript will go to top of the page, when the link is clicked.
// JavaScript Document

var up_timer

function getPosition(){
yoko = document.body.scrollLeft || document.documentElement.scrollLeft;
tate = document.body.scrollTop  || document.documentElement.scrollTop;

}

function pageup(x,y){
if(up_timer) clearTimeout(up_timer);
if(y >= 1){
getPosition();
var divisionY = (tate-(tate/5));
var Y = Math.floor(divisionY);
window.scrollTo(yoko,Y);
up_timer = setTimeout("pageup("+yoko+","+Y+")",2);
}else{
window.scrollTo(yoko,0);
clearTimeout(up_timer);
}
}

function scrollup(){
getPosition();
pageup(yoko,tate)
}
