分页链接不起作用

如何解决分页链接不起作用

| 我已经在网上搜索了一下，但找不到真正的代码问题。下一个和上一个链接不起作用。它只会获得第一个条目。 希望你们能对此有所帮助！谢谢。

<?php 
// ROWS DISPLAYED PER PAGE
$rows_per_page = 1;

// GET PAGE NUMBER
$page = $_GET[\'page\'];
$offset = (!empty($page)) ? $page : $page = 1;

// URL CLEAN UP
$self = $_SERVER[\'PHP_SELF\'].\"?\".$_SERVER[\'QUERY_STRING\'];
$self = str_replace(\"page={$offset}\",\"\",$self); 

// GET LIST OF STATES
$offset = ($page) ? ($page - 1) * $rows_per_page : 0; 
$id = $_GET[\'id\'];
$sql = \"SELECT * FROM updates WHERE update_categoryID = \'$id\' ORDER BY update_date          DESC LIMIT {$offset},{$rows_per_page}\";
$result = mysql_query($sql)or die(\'Error,query failed\');

// GET NUMBER OF PAGES
$query1 = \"SELECT * FROM updates WHERE update_categoryID = \'$id\'\"; 
$result1 = mysql_query($query1)or die(\'Error,query failed\');
$total = mysql_num_rows($result1);
$NumPgs = ceil($total/$rows_per_page);

while($row = mysql_fetch_assoc($result)) 
{
?>
<h2><?php echo $row[\'update_title\']; ?></h2>
 <p class=\"datetime\"><?php echo $row[\'update_date\'];?></p>
 <br>
 <p class=\"post\"><?php echo $row[\'update_content\'];?></p> 
 <a href=\"blogcomment.php?id=<?php echo $row[\'update_id\'];?>\">Post a Comment</a>
 <?php
 }
 ?>
<span style=\"float:right\">
<? if ($NumPgs > 0 && $page!=1) {
echo \"<a href=\\\"{$self}page=\".($page- 1).\"\\\">&lt;&lt;Prev</a>&nbsp;&nbsp;\"; } ?>
[Page <?php echo $page; ?>]
<? if ($page < $NumPgs) {
echo \"<a href=\\\"{$self}page=\".($page+1).\"\\\">&nbsp;&nbsp;Next&gt;&gt;</a>\"; } ?>
<b><? echo $offset+1;?> to <? echo $offset+$rows_per_page;?>,of <? echo $total; ?>  Entries</b>
</span>
</div>  

    

解决方法

嗯，也许您的页面参数已附加到查询字符串中，请尝试以下操作：

 $self = $_SERVER[\'PHP_SELF\'].\"?\".
         preg_replace( $_SERVER[ \'QUERY_STRING\' ],\'page=[0-9]+\',\'\');

代替 ：

 // URL CLEAN UP
 $self = $_SERVER[\'PHP_SELF\'].\"?\".$_SERVER[\'QUERY_STRING\'];
 $self = str_replace(\"page={$offset}\",\"\",$self);  

    ,短打开标签不适用于您的情况。 http://us3.php.net/echo http://us3.php.net/manual/zh/ini.core.php#ini.short-open-tag 请尝试以下代码。

<?php 
    // ROWS DISPLAYED PER PAGE
    $rows_per_page = 1;

    // GET PAGE NUMBER
    $page = $_GET[\'page\'];
    $offset = (!empty($page)) ? $page : $page = 1;

    // URL CLEAN UP
    $self = $_SERVER[\'PHP_SELF\'].\"?\".$_SERVER[\'QUERY_STRING\'];
    $self = str_replace(\"page={$offset}\",$self); 

    // GET LIST OF STATES
    $offset = ($page) ? ($page - 1) * $rows_per_page : 0; 
    $id = $_GET[\'id\'];
    $sql = \"SELECT * FROM updates WHERE update_categoryID = \'$id\' ORDER BY update_date          DESC LIMIT {$offset},{$rows_per_page}\";
    $result = mysql_query($sql)or die(\'Error,query failed\');

    // GET NUMBER OF PAGES
    $query1 = \"SELECT * FROM updates WHERE update_categoryID = \'$id\'\"; 
    $result1 = mysql_query($query1)or die(\'Error,query failed\');
    $total = mysql_num_rows($result1);
    $NumPgs = ceil($total/$rows_per_page);

    while($row = mysql_fetch_assoc($result)) 
    {
    ?>
    <h2><?php echo $row[\'update_title\']; ?></h2>
     <p class=\"datetime\"><?php echo $row[\'update_date\'];?></p>
     <br>
     <p class=\"post\"><?php echo $row[\'update_content\'];?></p> 
     <a href=\"blogcomment.php?id=<?php echo $row[\'update_id\'];?>\">Post a Comment</a>
 <?php
}
?>
    <span style=\"float:right\">
   <? echo ($prev = ($NumPgs > 0 && $page!=1) ? \"<a href=\\\"{$self}&page=\".($page- 1).\"\\\">Prev</a>&nbsp;&nbsp;\": 
   \"Prev&nbsp;&nbsp;\"); ?>
    [Page <?php echo $page; ?>]
   <? echo ($next = ($page < $NumPgs) ? \"<a href=\\\"{$self}&page=\".     ($page+1).\"\\\">Next</a>\": 
    \"Next\");?>&nbsp;
    <b>&nbsp;<? echo $offset+1?> to <?=$offset+$rows_per_page?>,of <? echo $total?> Entries</b>
    </span>
    </div>
