I have been trying to use paging for a record set.
the results are passed to the page from a url link which is fine but when i click on the next links the link is not being passed and i get no results. can anyone help with my code? ineed to pass $var onto following pages I guess but i cant see how
<?php
// Get the search variable from URL
$var = @$_GET['recordID'] ;
$trimmed = trim($var); //trim whitespace from the stored variable
// rows to return
$limit=10;
// check for a search parameter
if (!isset($var))
{
echo "<p>We dont seem to have a search parameter!</p>";
exit;
}
//connect to your database ** EDIT REQUIRED HERE **
mysql_connect("localhost","####","@@@@@"); //(host, username, password)
//specify database ** EDIT REQUIRED HERE **
mysql_select_db("Database") or die("Unable to select database"); //select which database we're using
// Build SQL Query
$query = "select * from TABLE NAME where field1 like \"%$trimmed%\"
order by created DESC"; // EDIT HERE and specify your table and field names for the SQL query
$numresults=mysql_query($query);
$numrows=mysql_num_rows($numresults);
if ($numrows == 0)
{
echo "<h4>Results</h4>";
echo "<p>Sorry, your search returned zero results</p>";
}
// next determine if s has been passed to script, if not use 0
if (empty($s)) {
$s=0;
}
// get results
$query .= " limit $s,$limit";
$result = mysql_query($query) or die("Couldn't execute query");
// begin to show results set
print "<div class= \"header\">";
print "<div class= \"cellh\">";
echo "Date<br />";
print "</div>";
print "<div class= \"cellhtitle\">";
echo "</b>Title</b>";
print "</div>";
print "<div class= \"cellh\">";
echo "Location<br />";
print "</div>";
print "</div>";
$count = 1 + $s ;
// now you can display the results returned
while ($row= mysql_fetch_array($result)) {
$title = $row["created"] ;
$title = date("d/m/y");
print "<div class= \"job\">";
print "<div class= \"cell\">";
echo " $title ";
print "</div>";
print "<div class= \"celltitle\">";
echo $row["company"] ;
print "</div>";
print "<div class= \"cell\">";
echo $row["city"];
print "</div>";
print "</div>";
print "</div>";
$count++ ;
}
$currPage = (($s/$limit) + 1);
//break before paging
echo "<br />";
// next we need to do the links to other results
if ($s>=1) { // bypass PREV link if s is 0
$prevs=($s-$limit);
print " <a href=\"$PHP_SELF?s=$prevs&q=$var\"><<
Prev</a>  ";
}
// calculate number of pages needing links
$pages=intval($numrows/$limit);
// $pages now contains int of pages needed unless there is a remainder from division
if ($numrows%$limit) {
// has remainder so add one page
$pages++;
}
// check to see if last page
if (!((($s+$limit)/$limit)==$pages) && $pages!=1) {
// not last page so give NEXT link
$news=$s+$limit;
echo " <a href=\"$PHP_SELF?s=$news&q=$var\">Next >></a>";
}
$a = $s + ($limit) ;
if ($a > $numrows) { $a = $numrows ; }
$b = $s + 1 ;
echo "<p>Showing results $b to $a of $numrows</p>";
?>
