我有181个产品的数据库。
我使用php在页面上显示产品。
它每页显示20个产品,总共有10页,在最后一页,第10页只有一个产品。
对于181种产品,分页从第0页开始,如< 0 1 2 3..10 >
。
对于像180这样的舍入值,分页显示正确< 1 2 3..10 >
。
function buildTrail($param = ""){
$cur_page = basename($_SERVER['PHP_SELF']);
$link = $_SERVER['REQUEST_URI'];
$link_array = explode('/', $link);
//$count = count($link_array);
$pagename = $link_array[1];
// echo $magename;
//echo $link;
if(is_array($param)){
foreach($param as $a => $b){
if($a != "page" && $a != "b" && $a != "q" && $a != "oferta"){
$url = "/".$b."/pg/";
}elseif($a == "b"){
$url = "/".$pagename."/brand/".$b."/pg/";
}elseif($a == "oferta"){
$url = "/".$pagename."/".$a."/pg/";
}else{
$url = "/".$pagename."/".$b."/pg/";
}
}
}else {
$url = $param;
}
// print_r($b);
$trail = "";
if($this->getPages() > 1){
if($this->getFrom() > 1){
$trail .= "<a href='" . WEBSITE . $url . $this->getPrevious()."'>«</a>\n ";
}
if($this->getFrom() < 10 && $this->getPages() > 10){
for ($i = 1; $i <= 10; $i++){
$trail .= "<a class='". ($i == $this->getFrom() ? "selected" : "links") . "' href='". WEBSITE .$url. $i ."'>" . $i . "</a>\n ";
}
} elseif($this->getFrom() < 10 && $this->getPages() < 10){
for ($i = 1; $i <= $this->getPages(); $i++){
$trail .= "<a class='". ($i == $this->getFrom() ? "selected" : "links") . "' href='". WEBSITE .$url. $i ."'>" . $i . "</a>\n ";
}
}elseif ($this->getFrom() >= 10 && $this->getFrom() <= ($this->getPages() - 5) ){

改变其他方式
for ($i = ($this->getPages() - 10); $i <= $this->getPages(); $i ++){
$trail .= "<a class='". ($i == $this->getFrom() ? "selected" : "links") . "' href='" . WEBSITE . $url. $i ."'>" . $i . "</a>\n ";
}
与
for ($i = 1; $i <= $this->getPages(); $i ++){
$trail .= "<a class='". ($i == $this->getFrom() ? "selected" : "links") . "' href='" . WEBSITE . $url. $i ."'>" . $i . "</a>\n ";
}
