problem with query error


Posted on 16th Feb 2014 07:03 pm 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
