无标题文件
$pagenum变量中没有值
设置$pagenum=$\u GET['pagenum']它会工作的
$pagenum = $_GET['pagenum'];
if (!(isset($pagenum))) {
$pagenum = 1;
}
分页示例
PHP中的分页示例
.分页{
背景色：#039A；
字体大小：30px；
文本对齐：居中；
左边距：自动；
右边距：自动；
宽度：50%；
}
.a_链接{
文字装饰：无；
颜色：红色；
填充物：5px；
}
.a_活动{
颜色：白色；
}
在新代码中，它们是。而不是，查看并使用or。您可以使用with prepared语句编辑上述代码吗？mysqli或PDO没有得到它，我应该在哪一行更改itadd$pagenum=$\u get['pagenum']；在if（！（isset（$pagenum））{$pagenum=1；}之前
