simple question in PHP

Hi,

I wonder if this line is correct. It seems not to work in my file

if ( ($img_id <= $temp ) and ($temp < $img_id + 10)) {echo $temp;};

Code (markup):

I have 28 pictures to be shown, 10 per page, but only 2 pages show up

thanks in advance

 

Try setting a new variable for $img_id+10 before you do the if statement.

$img_id_max=$img_id+10;
if ( ($img_id <= $temp ) and ($temp < $img_id_max)) {echo $temp;};

PHP:

 

still not working, it shows like there are only 20, it shows 2 pages

 

I assume img_id runs from 1 to 28? What is the temp variable?

 

function lesexamples ($sex)
	{
		if ($_GET[page_num] == "")
			{$page_num = 1;} 
			else {$page_num = $_GET[page_num];
			};
			
		$k = mysql_query("SELECT * FROM lesexamples WHERE sex='{$sex}'");
		$exemple_qty = mysql_num_rows($k);

		$page_qty = ceil ($exemple_qty/10);
		echo '<table width="100%" cellspacing="0" cellpadding="0" border="0">';
		$img_id = ($page_id - 1)* 10 +1;
		$img_id_max=$img_id+10;
		while ($z = mysql_fetch_array($k)) {
			$temp++;
			if ( ($img_id <= $temp ) and ($temp < $img_id_max)) {echo $temp;};

						
			
			};
			
	echo '<tr><td colspan="2" height="15"></td></tr>'; ?>
		<tr><td colspan="2" height="15" align="center">
		
		<?
		for ($i = 1; $i <= $page_qty; $i++)
		{
			if ($i == $page_num)
				{ echo $page_num;} 
				else { echo ' <a href="main.php?page_id=3&section_id='. $_GET[section_id] .'&page_num=' . $i . '">' . $i.'</a> '; };
		}; ?>
		
	</td></tr>
	<tr><td colspan="2" height="15" align="center">
	
	<?
	if ($page_num != 1)							
		{ 	$link_page_num = $page_num - 1;
			echo '<a href="main.php?page_id=3&section_id='. $_GET[section_id] .'&page_num=' . $link_page_num . '">Previous</a>&nbsp;&nbsp;&nbsp;';}
		else {echo 'Previous&nbsp;&nbsp;&nbsp;';}
	if ($page_num != $page_qty)							
		{ 	$link_page_num = $page_num + 1;
			echo '&nbsp;&nbsp;&nbsp;<a href="main.php?page_id=3&section_id='. $_GET[section_id] .'&page_num=' . $link_page_num . '">Next </a>';}
		else {echo '&nbsp;&nbsp;&nbsp;Next';}
		
	?>
	</td></tr>
	</table>
	<?
};

Code (markup):

 

I still can't see where the temp variable is being set?

 

it comes from the DB, We have fixed the problem now, but thank you for your help
