限制分页页数

}
$Prev_Page = $Page - 1;
$Next_Page = $Page + 1;
$Page_Start = (($Per_Page * $Page) - $Per_Page);

$Num_Pages = 1;
} elseif (($Num_Rows % $Per_Page) == 0) {
$Num_Pages = ($Num_Rows / $Per_Page) ;
} else {

$Num_Pages = (int) $Num_Pages;
}
$strSQL .=" order by addedrec_ID DESC LIMIT $Page_Start , $Per_Page";
$objQuery = mysql_query($strSQL) or trigger_error(mysql_error());;
if ($Prev_Page) {
echo " <a href ='$_SERVER[SCRIPT_NAME]?Page=$Prev_Page&txtName=$getname&txtState=$getstate&txtCell=$getcell&txtGroup=$getgroup'><< Back</a> ";
}
for ($i=1; $i <= $Num_Pages; $i++) {
if ($i != $Page) {
echo " <a href ='$_SERVER[SCRIPT_NAME]?Page=$i&txtName=$getname&txtState=$getstate&txtCell=$getcell&txtGroup=$getgroup'>$i</a> ";
} else {
echo "<b> $i </b>";
}
}
if ($Page!=$Num_Pages) {
echo " <a href ='$_SERVER[SCRIPT_NAME]?Page=$Next_Page&txtName=$getname&txtState=$getstate&txtCell=$getcell&txtGroup=$getgroup'>Next>></a> ";
}
mysql_close($objConnect);这是我用来为data search.But创建分页页面的代码。我只是注意到我有太多的记录，那么它就会有太多的页码。我正在尝试限制显示的页码，并寻找许多示例..it有很多方法可以做到这一点，但我仍然不知道如何限制我的方法...

好的，如果你的意思是展示一些东西，比如
Prev 1 2 3 4 5 6 .. 40 41 Next
Prev 1 2 .. 6 7 8 9 10 .. 40 41 Next我们需要做的第一件事是创建一个函数，该函数可以处理输出分页所需的内容。下面是我使用的一个函数，它工作得很好。
function get_paging_info($tot_rows,$pp,$curr_page)
{
$pages = ceil($tot_rows / $pp); // calc pages
$data = array(); // start out array
$data['si'] = ($curr_page * $pp) - $pp; // what row to start at
$data['pages'] = $pages; // add the pages
$data['curr_page'] = $curr_page; // Whats the current page
return $data; //return the paging data
}现在这个函数非常可靠，对我来说工作得很好。
所以你要传递这个函数
- $tot_rows =查询的行数
- $pp=每页的项目数=当前页码
好了，现在您有了所需的数据，您需要显示它。
这是我的用法，在你想“啊，它太长了”之前，请先读一读。这实际上非常简单。
下面是它将返回的内容的快照
<!-- Create the query -->
<?php $count = mysql_fetch_assoc( mysql_query ( "SELECT COUNT( rows ) as count FROM table" ) ) ;
<?php $count = $count[0]['count']; ?>
<!-- Call our function from above -->
<?php $paging_info = get_paging_info($count,5,34); ?>
<p>
<!-- If the current page is more than 1, show the First and Previous links -->
<?php if($paging_info['curr_page'] > 1) : ?>
<a href='' title='Page 1'>First</a>
<a href='' title='Page <?php echo ($paging_info['curr_page'] - 1); ?>'>Prev</a>
<?php endif; ?>
<?php
//setup starting point
//$max is equal to number of links shown
$max = 7;
if($paging_info['curr_page'] < $max)
$sp = 1;
elseif($paging_info['curr_page'] >= ($paging_info['pages'] - floor($max / 2)) )
$sp = $paging_info['pages'] - $max + 1;
elseif($paging_info['curr_page'] >= $max)
$sp = $paging_info['curr_page'] - floor($max/2);
?>
<!-- If the current page >= $max then show link to 1st page -->
<?php if($paging_info['curr_page'] >= $max) : ?>
<a href='' title='Page 1'>1</a>
..
<?php endif; ?>
<!-- Loop though max number of pages shown and show links either side equal to $max / 2 -->
<?php for($i = $sp; $i <= ($sp + $max -1);$i++) : ?>
<?php
if($i > $paging_info['pages'])
continue;
?>
<?php if($paging_info['curr_page'] == $i) : ?>
<span class='bold'><?php echo $i; ?></span>
<?php else : ?>
<a href='' title='Page <?php echo $i; ?>'><?php echo $i; ?></a>
<?php endif; ?>
<?php endfor; ?>
<!-- If the current page is less than say the last page minus $max pages divided by 2-->
<?php if($paging_info['curr_page'] < ($paging_info['pages'] - floor($max / 2))) : ?>
..
<a href='' title='Page <?php echo $paging_info['pages']; ?>'><?php echo $paging_info['pages']; ?></a>
<?php endif; ?>
<!-- Show last two pages if we're not near them -->
<?php if($paging_info['curr_page'] < $paging_info['pages']) : ?>
<a href='<?php echo str_replace('/page'.$paging_info['curr_page'], '', $paging_info['curr_url']) . '/page'.($paging_info['curr_page'] + 1); ?>' title='Page <?php echo ($paging_info['curr_page'] + 1); ?>'>Next</a>
<a href='<?php echo str_replace('/page'.$paging_info['curr_page'], '', $paging_info['curr_url']) . '/page'.$paging_info['pages']; ?>' title='Page <?php echo $paging_info['pages']; ?>'>Last</a>
<?php endif; ?>
