problem with query error

Posted on 16th Feb 2014 by admin

First Thanks to those who helped me on my previous posts, and the following code i'm using is not mine, i grabbed it from here http://www.phpfreaks.com/tutorial/basic-pagination

Now onto the problem...

If i make a search query, i get the following error:

Problem, with Query:Unknown column 'math' in 'where clause'

Not sure were the problem is in the script but here it is

Code: <?php
$subject = $_GET['subject'];
$location = $_GET['location'];

// find out how many rows are in the table
$sql = "SELECT COUNT(*) FROM tutorProfiles";
$result = mysql_query($sql) or trigger_error("SQL", E_USER_ERROR);
$r = mysql_fetch_row($result);
$numrows = $r[0];

// number of rows to show per page
$rowsperpage = 9;
// find out total pages
$totalpages = ceil($numrows / $rowsperpage);

// get the current page or set a default
if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) {
// cast var as int
$currentpage = (int) $_GET['currentpage'];
} else {
// default page num
$currentpage = 1;
} // end if

// if current page is greater than total pages...
if ($currentpage > $totalpages) {
// set current page to last page
$currentpage = $totalpages;
} // end if
// if current page is less than first page...
if ($currentpage < 1) {
// set current page to first page
$currentpage = 1;
} // end if

// the offset of the list, based on current page
$offset = ($currentpage - 1) * $rowsperpage;

//retrieve the info from DB
$sql = 'SELECT * FROM tutorProfiles WHERE subject='.$subject.' AND location='.$location.' LIMIT '.$offset.', '.$rowsperpage.'';
$result = mysql_query($sql) or die("Problem, with Query:".mysql_error());

// while there are rows to be fetched...
while ($list = mysql_fetch_assoc($result)) {
// echo data
echo '
<div id="profileBox">
<div id="badgeImg">
<img src="images/imgBG.png" name="imgBadge" width="76" height="70" align="left" id="imgBadge" />
<h2>'.$list['first'].'</h2>
<p>'.$list['school'].'<br />
'.$list['degree'] . $list['class'].'
</p>
</div>
<div id="profleBtn">
<a href="profile.php?id='.$list['tutorId'].'"><img src="images/linkBtn.png" alt="view Profile" width="150" height="30" border="0" /></a>
</div>
</div>';
} // end while
if($result>0){
/*********** Start the pagination links ********/
echo "<p style="clear:both;" align="center">n";
// range of num links to show
$range = 3;

// if not on page 1, don't show back links
if ($currentpage > 1) {
// show << link to go back to page 1
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=1&subject=$subject&location=$location&search2=Search'><<</a> ";
// get previous page num
$prevpage = $currentpage - 1;
// show < link to go back to 1 page
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$prevpage&subject=$subject&location=$location&search2=Search'><</a> ";
} // end if

// loop to show links to range of pages around current page
for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {
// if it's a valid page number...
if (($x > 0) && ($x <= $totalpages)) {
// if we're on current page...
if ($x == $currentpage) {
// 'highlight' it but don't make a link
echo " [<b>$x</b>] ";
// if not current page...
} else {
// make it a link
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x&subject=$subject&location=$location&search2=Search'>$x</a> ";
} // end else
} // end if
} // end for

// if not on last page, show forward and last page links
if ($currentpage != $totalpages) {
// get next page
$nextpage = $currentpage + 1;
// echo forward link for next page
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$nextpage&subject=$subject&location=$location&search2=Search'>></a> ";
// echo forward link for lastpage
echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$totalpages&subject=$subject&location=$location&search2=Search'>>></a> ";
} // end if
echo "</p>n";
/****** end build pagination links ******/
}
?>

I hope i'm explaining myself in what my problem is
