抱歉，我之前在 wordpress 上错误地提出了这个问题。我正在处理分页，但我面临一个问题，当我单击下一步时，它会增加下一页的查询字符串中的数字，但页面上的数据保持不变，我需要显示接下来的四条记录，因为我已经显示了每条记录页。代码看起来不错，但我不知道为什么它不起作用。下面是代码
$page = 0;
if($page == 0){
$page = "1";
}else{
// If page is set, let's get it
echo $page = $_GET['page'];
}
// Now lets get all messages from your database
$sql = "select * from about_us where sbmenu_id=9991";
$query = mysql_query($sql);
// Lets count all messages
$num = mysql_num_rows($query);
// Lets set how many messages we want to display
$per_page = "4";
// Now we must calculate the last page
$last_page = ceil($num/$per_page);
// And set the first page
$first_page = "1";
// Here we are making the "First page" link
echo "<a href='?page=".$first_page."'>First page</a> ";
echo $page ;
// If page is 1 then remove link from "Previous" word
if($page == $first_page){
echo "Previous ";
}else{
if(!isset($page)){
echo "Previous";
}else{
// But if page is set and it's not 1.. Lets add link to previous word to take us back by one page
$previous = $page-1;
echo "<a href='?page=".$previous."'>Previous</a> ";
}
}
// If the page is last page.. lets remove "Next" link
if($page == $last_page){
echo "Next ";
}else{
// If page is not set or it is set and it's not the last page.. lets add link to this word so we can go to the next page
if(!isset($page)){
$next = $first_page+1;
echo "<a href='?page=".$next."'>Next</a> ";
}else{
$next = $page+1;
echo "<a href='?page=".$next."'>Next</a> ";
}
}
// And now lets add the "Last page" link
echo "<a href='?page=".$last_page."'>Last page</a>";
// Math.. It gets us the start number of message that will be displayed
$start = ($page-1)*$per_page;
// Now lets set the limit for our query
$limit = "LIMIT $start, $per_page";
// It's time for getting our messages
$sql = "select * from about_us where sbmenu_id=9991 $limit";
$query = mysql_query($sql);
?><table><?php
echo "<br /><br /><tr style='height:70px;'>";
// And lets display our messages
while($row = mysql_fetch_array($query) or die(mysql_error()))
{....}
