我正在为我正在设计的一个网站创建一个脚本,该脚本将使用分页从数据库中提取引号,
我已经很好地完成了这部分,设置分页类并实际使其打印出结果,但我一直试图使其使用编号系统打印-就像每个一样。
我希望每个引用都有自己的编号,如:
- "一个人不能超越他的影子";
- "foo不是傻瓜,只是在php中使用"
-
"so on and so forth";
看我的课:
class pagination extends cleanPost{ var $p=1, $max_r,$limits; var $count_all=0,$sql,$total,$table,$totalres,$totalpages; var $r,$i; var $show=10; function setMax($max_r){ $this->p = $this->clean($_GET['p']); $this->max_r = $max_r; if(empty($this->p)) { $this->p = 1; } $this->limits = ($this->p - 1) * $this->max_r; } function setData($table){ $this->table = $table; $this->sql = "SELECT * FROM ".$this->table." LIMIT ".$this->limits.",".$this->max_r.""; $this->sql = mysql_query($this->sql) or die(mysql_error()); $this->total = "SELECT * FROM ".$this->table.""; $this->totalres = mysql_query($this->total) or die(mysql_error()); $this->count_all = mysql_num_rows($this->totalres); // count all the rows $this->totalpages = ceil($this->count_all / $this->max_r); // work out total pages } function displayLinks($show){ $this->show = $show; // How many links to show echo "<br><br>"; if($this->p > 1) // If p > then one then give link to first page { $pagination .= "<div class="pagination"> <a href=?p=1> [first] </a> "; } else { // else show nothing $pagination .= "<div class="pagination">".""; } if($this->p != 1) { // if p aint equal to 1 then show previous text $previous = $this->p-1; $pagination .= "<a href=?p=$previous>«prev</a>"; } else { //else show nothing $pagination.= "<span class="disabled">first</span>".""; } for($i =1; $i <= $this->show; $i++) // show ($show) links { if($this->p > $this->totalpages) { // if p is greater then totalpages then display nothing echo ""; } else if($_GET["p"] == $this->p) { //if p is equal to the current loop value then dont display that value as link $pagination .= $this->p ; } else{ $pagination .= " <a href=?p=".$this->p."> ".$this->p." </a>"; // else display the rest as links } $this->p++; //increment $p } if($_GET["p"] == $this->totalpages) {// if page is equal to totalpages then dont display the last page at the end of links $pagination.= "<span class="disabled">last</span>".""; } else if($_GET["p"] != $this->totalpages) { // $pagination .= "..."; // display dots # $pagination .= "<a href=?p=".$this->totalpages."> ".$this->totalpages." </a>"; } else { // else display the last page link after other ones } if($_GET["p"] < $this->totalpages)// if p is less then total pages then show next link { $next = $_GET["p"] + 1; $pagination .= "<a href=?p=$next> next»</a>"; $pagination.= "<a href=?p=".$this->totalpages."> [last] </a>".""; } $pagination.= "</div>n"; echo $pagination;
}
//////////这是我的报价显示页面
$page= new pagination; $page->setMax(5);//set the maximum quote shown per page $page ->setData("quotes"); $page ->display(); echo "<table border=1 width=100%>"; while ($row = mysql_fetch_array($page->sql)) { echo $num_results = mysql_num_rows($page->sql); echo "<tr>"; for ($i=0; $i <$num_results; $i++) { echo "<td>"; $num_found = $i + 1; echo $num_found.$row['ngwaquote']; echo "</td>"; } echo "</tr>"; } echo "</table><p>"; $page ->displayLinks(4) ;
得到的结果是,如果我点击分页链接中的第一个数字给我quote.html吗?p = 1
我让他们按顺序列出页:11[quote]滚石不生苔。[/quote]
滚石不生苔。[/quote]
[quote]滚石不生苔。[/quote]
滚石不生苔。[/quote]
5[quote]滚石不生苔。[/quote]但是另一个页面quote.html?p=2 而不是从开始第2页:6 (qoute)没有[/quote]滚石不生苔。[/quote]
rather重新开始从1开始计数页:11 (qoute)没有[/quote][quote]滚石不生苔。[/quote]
我希望它看起来像我们在BBC足球博客评论2页从101开始而不是从1重新开始
我希望我的问题不会太长而无法理解,如果我很抱歉,只是想把它们都贴出来以便更好地理解。
我想你可能把问题复杂化了。一些伪代码:
Current number = Number of items per page * Current page number
Current page number
来自您的URL,带有?p=
GET参数。
然后在每次迭代中回显一个引号,给Current number
加一个。
