pagination/session variables?

[__greg]

I'm creating a news page where visitors to my site can search previous news posts based on criteria they enter in a text box..

i can get the search function to work fine, but sometimes, there might be a lot of results (depending on what they search for) and i'd like to span that data over as many pages as it needs.

I can't figure out how to keep the original search query going and build the next pages..

Here's is a piece of my script (when the user clicks search). and i also included the section that displays the individual post..

if ($_POST[op] == "search") {

		if(!isset($_GET['page'])){ 
		$page = 1; 
		} else { 
			$page = $_GET['page']; 
		} 

		// Define the number of results per page 
		$max_results = 25; 

		// Figure out the limit for the query based 
		// on the current page number. 
		$from = (($page * $max_results) - $max_results); 

		// Perform MySQL query on only the current page number's results 

		$get_results = "SELECT *,date_format(date,'%m/%d/%Y') AS frm_date FROM news WHERE body LIKE '%".$_POST[newssearch]."%' ORDER BY date DESC LIMIT $from, $max_results";
		$get_results_res = mysql_query($get_results) or die(mysql_error());

		$display_block = "<table>";

		if (mysql_num_rows($get_results_res) == "0") {
		$display_block = "<tr><td>There is no news about &quot;<b>".$_POST[newssearch]."</b>&quot;.</td></tr>";
		}

		if (mysql_num_rows($get_results_res) > "0") {
		$display_block = "<tr><td>Results for &quot;<b>".$_POST[newssearch]."</b>&quot;</td></tr><tr><td>";



		while($row = mysql_fetch_array($get_results_res)){ 
			$id = $row["id"];
			$date = $row["frm_date"];
			$title = $row["title"];
			$body = $row["body"];
			// Build your formatted results here. 
			$display_block .= "<a href=\"newnews.php?id=$id\">$title</a> ($date)<br>";
		} 

		$display_block .= "</td></tr>";

		// Figure out the total number of results in DB: 
		$total_results = mysql_result(mysql_query("SELECT COUNT(*) as Num FROM news WHERE body LIKE '%".$_POST[newssearch]."%'"),0); 

		// Figure out the total number of pages. Always round up using ceil() 
		$total_pages = ceil($total_results / $max_results); 

		// Build Page Number Hyperlinks 
		$display_block .= "<tr><td>Select a Page<br />"; 

		// Build Previous Link 
		if($page > 1){ 
			$prev = ($page - 1); 
			$display_block .= "<a href=\"".$_SERVER['PHP_SELF']."?page=$prev\"><<Previous</a>&nbsp;"; 
		} 

		for($i = 1; $i <= $total_pages; $i++){ 
			if(($page) == $i){ 
				$display_block .= "$i&nbsp;"; 
				} else { 
					$display_block .= "<a href=\"".$_SERVER['PHP_SELF']."?page=$i\">$i</a>&nbsp;"; 
			} 
		} 

		// Build Next Link 
		if($page < $total_pages){ 
			$next = ($page + 1); 
			$display_block .= "<a href=\"".$_SERVER['PHP_SELF']."?page=$next\">Next>></a>"; 
		} 
		$display_block .= "</td></tr>"; 




	}
}


if ($_GET[id]) {
	$get_news = "SELECT *,date_format(date,'%W, %M %D, %Y | %l:%i%p') AS frm_date FROM news WHERE id = '".$_GET[id]."'";
	$get_news_res = mysql_query($get_news) or die(mysql_error());

while($row = mysql_fetch_array($get_news_res)) {
	$id = $row["id"];
	$date = $row["frm_date"];
	$image = $row["image"];
	$title = $row["title"];
	$body = $row["body"];

	$display_block = "<tr><a name=$id></a>
						<td valign=top width=200 align=center><img src=images/news/$image width=200 border=1></td>
						<td valign=top><b>$title</b><br>
						<span class=date>$date</span><br>

						</tr>
						<tr><td valign=top colspan=2 align=right><a href=javascript:; onClick=MM_openBrWindow('sendtoafriend.php?id=$id','','width=410,height=220,resizable=yes')><img src=images/news/stafspacer.gif border=0></a></td></tr>";
