counter help - Pure PHP - self created pagination - php

Question

The code I have works absolutely perfectly:
<?
$maxresults = 10;
$total = $row[total];
$pagecount = $total / $maxresults;
if (!isset($_GET['page'])) { $_GET['page'] = '1'; }
$startcount = (($_GET['page'] - 1) * $maxresults + 1);
$stopcount = $startcount + ($maxresults - 1);
$lastTime = null;
$i='0';
$sc = $startcount;
$stmt=$db->prepare("// SELECT STATEMENT");
$stmt->bindParam(':user', $username);
$stmt->execute();
while ( $row = $stmt->fetch() ) {
if (!($sc > $stopcount)) {
$i++;
if( $row['time'] !== $lastTime ) {
if ( $lastTime === NULL ) {
echo '// close of loop';
} else {
echo '// loop grouping as title';
}
$lastTime = $row['time'];
}
if ($i >= $sc) { ?>
// the html to loop
<?
$sc++;
}
}
}
?>
Forward and Back buttons are easy enough to create. if $_GET['page'] * 10 > $total, active the next button, if $_GET['page'] > 1 activate previous button.
What I can't figure out is the correct formula and loop so I can always display the correct number of "page numbered" links. I want to always show 5 based on the 3rd number. So 1 would should 5 links: 1 - 5, 2 would also show 1 - 5, as would 3, 4 would show 2 - 6, 5 would show 3 - 7.
Now obviously, I could just add 2 and subtract 2 from the current $_GET[page] if the get page is greater than 3, but I need to take into account testing to see if the results go that high. So only if results are greater than 10 should number 2 show, and then if on page 16 pages 17 and 18 should only show if there are 170 and 180 results to display.
Perhaps I have just been staring at the code to long, but I can't seem to get a formula or loop correct in my head to even attempt the code page.

Answer 1

It was a fairly specific question. Wasn't sure if anyone would help with something so specific or not. Guess I learned.
Here is the answer to my own question:
<ul>
<li class="<? if ($_GET['page'] < '2') { echo 'disabled' ; } ?>">
<a href="<?
if ($_GET['page'] == '2') {
echo 'inbox.php';
} else {
echo '?page='.($_GET[page] - 1);
}
?>">Prev</a>
</li> <!-- previous button-->
<li style="<? if ($_GET['page'] - 2 < '1') { echo 'display:none;'; } ?>">
<a href="?page=<?
echo ($_GET[page] -2); ?>">
<? echo ($_GET[page] -2); ?>
</a>
</li> <!-- the button 2 before current spot if its greater than 0 -->
<li style="<? if ($_GET['page'] - 1 < '1') { echo 'display:none;'; } ?>">
<a href="?page=<?
echo ($_GET[page] -1); ?>">
<? echo ($_GET[page] -1); ?>
</a>
</li> <!-- the button 1 before current spot if its greater than 0 -->
<li class="disabled">
<? echo $_GET[page]; ?>
</li> <!-- current button disabled -->
<li style="<? if ($total - ($_GET[page] * 10) <= '0') { echo 'display:none;'; } ?>">
<a href="?page=<?
echo ($_GET[page] + 1); ?>">
<? echo ($_GET[page] +1); ?>
</a>
</li> <!-- the button 1 after current spot if results go that high -->
<li style="<? if ($total - ($_GET[page] + 1) * 10 <= '0') { echo 'display:none;'; } ?>">
<a href="?page=<?
echo ($_GET[page] + 2); ?>">
<? echo ($_GET[page] + 2); ?>
</a>
</li> <!-- the button 2 after current spot if results go that high -->
<li class="<? if ($total - ($_GET[page] * 10) <= '0') { echo 'disabled'; } ?>">
Next
</li> <!-- the next button if results go that high -->
</ul>

#bruce after seeing your solution, I'd like to give you my own solution.
$page = $_GET['page'];
$max_pages = ceil($total / $maxresults);
$min_pages = 1;
$start = max($min_pages, $page-2);
$end = min($max_pages, $start+2);
$nav = ($page > $min_pages ? '<li><</li>' : '' );
for ($i = $start; $i <= $end; $i++)
$nav .= '<li' . ($i == $page ? 'class="active"' : '' ) . '>' . $i . '</li>';
$nav .= ($page < $max_pages ? '<li>></li>' : '' );
