Search gives only one element from set - php

Question

There is a small problem. I have this 3 functions, and this functions make search in DB. But, that search give only one element from category (when we have 2 or more).
For example, if we have 1,2,3 searche give us only
1.
If we delete 1, it will be 2 and etc.
Any suggestions?
This is 3 functions
function displayList($clause) {
$clause = ' m.active=1 && g.active=1 && '.$clause;
$pageSize = 12;
$pageNo = isset($_GET['page'])? (int)$_GET['page']:0;
$qr = "SELECT count(DISTINCT m.id) FROM #tyregoods g, #tyremodels m WHERE m.id = g.owner_id && $clause";
$q = $this->execSQL($qr);
list($count) = $q->get();
$pageCount = ceil($count / $pageSize);
if (!$pageCount) $pageCount = 1;
if ($pageCount<=$pageNo) return false;
$offset = $pageNo * $pageSize;
list($sortV, $sort) = $this->getSort();
/*$q = $this->execSQL("SELECT m.id as modelid, m.icon, m.name, m.season, g.id, width, profile, diameter, studed, indx, side, remains, price
FROM #tyregoods g, #tyremodels m WHERE m.id = g.owner_id && $clause
ORDER BY $sortV LIMIT $pageSize OFFSET $offset ");*/
$q = "SELECT m.id as modelid, m.icon, m.name, m.season, g.id, width, profile, diameter, studed, indx, side, remains, price
FROM #tyregoods g, #tyremodels m WHERE m.id = g.owner_id && $clause GROUP BY m.id
ORDER BY $sortV LIMIT $pageSize OFFSET $offset";
$q = $this->execSQL($q);
$xml = '';
while ($data = $q->getAssoc()) {
$xml.=prop2xml($data);
}
return "<goodslist page='$pageNo' pagesize='$pageSize' pages='$pageCount' sort='$sort'>$xml</goodslist>";
}
function displayBySize() {
$params = $this->kernel->getModul('tyreparams');
$clause = $this->getSQLClause($params);
if ($clause['where'] == '') return '<noparams/>';
$xml = $this->displayList($clause).$params->display();
return "<search>$xml</search>";
}
function getSQLClause($params, $except = array()) {
$cl = array();
foreach($params->params as $id=>$param)
if ($param['value']!='' && !in_array($id, $except)){
$vl = trim($param['value']);
if ('vendor' == $id) {
$cl[] = "m.owner_id IN (SELECT ts.id FROM td_tyres ts WHERE ts.active=1 AND ts.id='$vl')";
}
else {
$pos = strpos($vl, '-');
if ($pos === 0) $pos = strpos($vl, '-', 1);
if ($pos) {
$lo = substr($vl, 0, $pos);
$hi = substr($vl, $pos + 1);
$t = "$id >= '$lo' && $id <= '$hi'";
}
else
$t = "$id = '$vl'";
if ($id == 'PCD') {
$t2 = str_replace('PCD', 'PCD2', $t);
$cl[] = "(($t) || ($t2))";
} else
$cl[] = $t;
}
}
return implode('&&', $cl);
}
UPD
SQL query -
SELECT m.id as modelid, m.icon, m.name, m.season, g.id, width, profile, diameter,
studed, indx, side, remains, price FROM td_tyregoods g, td_tyremodels m WHERE m.id =
g.owner_id && m.active=1 && g.active=1 && width = '245'&&profile = '50'&&m.owner_id IN
(SELECT ts.id FROM td_tyres ts WHERE ts.active=1 AND ts.id='13') GROUP BY m.id ORDER BY
name LIMIT 12 OFFSET 0
This query, give in mysql console exactly that we have at the site. Problem in query...
