[PHP-DEV] code for Alphabetical pager class

[austin swinney]

i think somebody is working on a pager class.  this class alpha could
either extend or be incorporated into a pager class.  it is composed of
two functions: _getAlphabet() accepts no arguements and returns an array
of the alphabet, getAlphabetNav ($page,$i) accepts (1)the link reference
page and (2) letter that is current (so as to not link it).

the code below returns an multi-dimentional array of html links with
urls that use the value $i=$char[a-z]:

http://www.example.com/users.php?i=m

example of html returned:

<a href='./users.php?i=a'>a</a> 
<a href='./users.php?i=b'>b</a> 
<a href='./users.php?i=c'>c</a> 
<a href='./users.php?i=d'>d</a> 
(...)

for example, in use:

<?php
/* get the alphabetical navigation
 */
require("Madmin/Alpha.php");
$a = new Alpha();
$alphNav=$a->getAlphabetNav($PHP_SELF,$i);

/*
 * then you can use the alphabetic character to 
 * do things like sql select statements:
 */

if ($i) {
    $query = "SELECT user_id, username, email FROM user WHERE username
LIKE '$i%'";
}
?>

here is the code for the class:

<?php
//$Id: Alpha.php,v 1.4 2002/02/26 01:05:40 austin Exp $

class Alpha {

    /**
     * get an array of alphabet for use inside the class
     */
    function _getAlphabet() {
        $_alphabet=array(1 => "a","b","c","d","e","f","g","h","i",
                          "j","k","l","m","n","o","p","q","r",
                          "s","t","u","v","w","x","y","z");
        return $_alphabet;
    }

    function getAlphabetNav ($page,$i) {
        $alphabet=$this->_getAlphabet();
        foreach ($alphabet as $key=>$val) {
           if ($val!="$i"||!"$i") {
               $links .= "<a href='$page?i=$key'>$val</a> ";
           } else {
               $links .= "$val ";
           }
        }
        return $links;
        unset($links);
    }

}
?>

comments appreciated :)
