【问题描述】:
我正在做一个网络搜索引擎项目。我正在研究分页功能。当我单击页面时,它会给出突然的结果并给出Undefined variable: page1 error。怎么办?
if(isset($_GET['page'])) //results displayed based on page selection
{
$page=$_GET['page'];
if($page=="" || $page=="1")
{
$page1=0;
}
else
{
$page1=($page*10)-10;
}
}
$numrows1 = mysqli_num_rows($query); // page evaluation and this statement calculates number of resultant rows
$a = $numrows1/10; //10 is for number of results per page and $a gives number of pages
$a = ceil($a);
echo "<br>"; echo "<br>";
for($b=1; $b<=$a; $b++)
{
?><a href="search.php?page=<?php echo $b; ?>" style="text-decoration:none;"><?php echo $b." ";?></a><?php
}
我希望我很清楚。谁能帮我解决这个问题?
