My plugin's Opendir() pagination problem – Plz Help

Hello everyone,

I am developing a WP plugin that has an option panel that requires pagination. What this panel is doing is opening a directory and finding it’s contents then showing the first 15 results in a paginated menu. My problem is that when a user clicks on the next page link or any page number my code appends an “?ID=” to the end of the url and the user is subsequently brought to a “You do not have sufficient permissions to access this page.” rather than the page refreshing and the icons set being displayed.

Now, I know this is a built-in WordPress security function but is there any workaround to this? How should I handle pagination without appending the URL with the ID? Any ideas are greatly appreciated.

Here’s my code:

<?php
	// Start of icons

	if( $_GET['id'] != '' )
		{
				$ID = $_GET['id'];
		}
		else
		{
				$ID = 0;
		}

	$directory = $wpicons_path."/icons/";

	$icon_dir=opendir($directory);

	$idCounter = 0;

	 while (($filename = readdir($icon_dir))) {
                // Place all of the pictures in an array.
                $PICTURES[$idCounter] = $filename;
                $idCounter++;

    }
    closedir($icon_dir);

	$totalPictures = count($PICTURES);

	  for( $i = 1; $i <= 15; $i++ )
        {
                if( $PICTURES[$ID + $i] != '' )
                {

                        echo '<img src="' .WP_PLUGIN_URL. '/wp-admin-icons/icons/' . $PICTURES[$ID + $i] . '" alt="..." />';

                        if( ($i % 5) == 0 )
                        {
                                echo "<br />";
                        }
                }

        }

	if( ($ID - 15) >= 0 )
        {
                echo '<a href="?id=' . ($ID - 15) . '">';
        }
        echo '<<</a> ';
        $pages = ceil($totalPictures / 15);
        for( $i = 0; $i < $pages; $i++ )
        {
                if( ($i * 15) != $ID )
                {
                        echo '<a href="https://localhost/testsite/wp-admin/options-general.php?page=wp-admin-icons.php/wp-admin-icons-init.php#id=' . ($i * 15) . '">';
                }
                echo ($i + 1). "</a> ";
        }
        if( ($ID + 15) < $totalPictures )
        {
                 echo '<a href="https://localhost/testsite/wp-admin/options-general.php?page=wp-admin-icons.php/wp-admin-icons-init.php#id=' . ($ID + 15) . '">';
        }
        echo '>></a>';
