こんにちは私は私のページングを終了し、フィルターと$ _POSTを使ってデータを抽出するフィルタシステムに問題がありますが、2番目のページに行くと意味がわかります何もないと私はいくつかのデータが不足している場合、私はそれ以上のフィルタを持っている、私は場所（ロンドン）でフィルタリングすれば36の32を得るが、私は2番目のページに行くとき、彼の意味ウサギは私のコードとライブのページです：My website
トップコード：
$cat1 = '';
$perpage = 10;
if(isset($_GET["catid"])){
$p1 = '';
$p2 = '';
$catid = $_GET["catid"];
$l1 = substr($catid,0,1);
$l2 = substr($catid,1,1);
$p1 = "CAT".$l1;
if(!empty($l2)){
$p2 = "CAT".$l1."-".$l2;
$p3 = $p2;
}
$cat1 = @$lang[$p1];
$cat2 = @$lang[$p2];
}
$postid = '';
$userid = '';
$pricemin = '';
$pricemax = '';
$location = '';
if(isset($_POST["filter"])){
$pricemin = $_POST["min"];
$pricemax = $_POST["max"];
$location = $_POST["location"];
}
///////////////////////////////////////PAGINATION //////////////////
if(empty($p1) && empty($p2)){
$sql = "SELECT * FROM posts p JOIN images i ON p.id = i.postid WHERE p.id > 0 ";
if(!empty($location)){
$sql .= "AND location='$location'";
}
if(!empty($pricemin)){
$sql .= "AND price>='$pricemin' ";
}
if(!empty($pricemax)){
$sql .= "AND price<='$pricemax' ";
}
} else if(!empty($p2)){
$sql = "SELECT * FROM posts p JOIN images i ON p.id = i.postid WHERE catid='$p2' ";
if(!empty($location)){
$sql .= "AND location='$location'";
}
if(!empty($pricemin)){
$sql .= "AND price>='$pricemin' ";
}
if(!empty($pricemax)){
$sql .= "AND price<='$pricemax' ";
}
} else {
$sql = "SELECT * FROM posts p JOIN images i ON p.id = i.postid WHERE p.catid LIKE '$p1%' ";
if(!empty($location)){
$sql .= "AND location='$location'";
}
if(!empty($pricemin)){
$sql .= "AND price>='$pricemin' ";
}
if(!empty($pricemax)){
$sql .= "AND price<='$pricemax' ";
}
}
$res = mysqli_query($connect,$sql);
$rows = mysqli_num_rows($res);
$last = ceil($rows/$perpage);
if($last < 1){
$last = 1;
}
$pagenum = 1;
if(isset($_GET["pn"])){
$pagenum = preg_replace("#[^0-9]#", "", $_GET["pn"]);
}
if($pagenum < 1){
$pagenum = 1;
} else if($pagenum > $last){
$pagenum = $last;
}
$limit = 'LIMIT ' .($pagenum - 1) * $perpage.',' .$perpage;
$paginationCtrls = '';
if($last != 1){
if ($pagenum > 1) {
$previous = $pagenum - 1;
$paginationCtrls .= '<a href="cat.php?catid='.$catid.'&pn='.$previous.'">Previous</a> ';
for($i = $pagenum-4; $i < $pagenum; $i++){
if($i > 0){
$paginationCtrls .= '<a href="cat.php?catid='.$catid.'&pn='.$i.'">'.$i.'</a> ';
}
}
}
$paginationCtrls .= ''.$pagenum.' ';
for($i = $pagenum+1; $i <= $last; $i++){
$paginationCtrls .= '<a href="cat.php?catid='.$catid.'&pn='.$i.'">'.$i.'</a> ';
if($i >= $pagenum+4){
break;
}
}
if ($pagenum != $last) {
$next = $pagenum + 1;
$paginationCtrls .= ' <a href="cat.php?catid='.$catid.'&pn='.$next.'">Next</a> ';

uは2ページ目を渡した場合、今$ _POSTがヌルに等しくなりますので、私はポストデータをキャッチし、uは再びPOSTメソッドまたは他の溶液でウサギを変更するまでそこに保つために、そのための可能な解決策を必要としますページ単位で
