Php 对分页的表应用搜索或筛选
你好，善良的先生们，你能帮我处理这个代码吗。我尝试做的是在搜索框中键入一些内容，例如pending，它将显示每页5个pending reservation（5行pending reservation）。但当我尝试时，它会显示所有超过10个的待定预订 这是图片 我想试试这样的。。但它什么也没表现出来Php 对分页的表应用搜索或筛选,php,mysql,Php,Mysql,你好，善良的先生们，你能帮我处理这个代码吗。我尝试做的是在搜索框中键入一些内容，例如pending，它将显示每页5个pending reservation（5行pending reservation）。但当我尝试时，它会显示所有超过10个的待定预订 这是图片 我想试试这样的。。但它什么也没表现出来 $query = "SELECT * FROM reservations WHERE CONCAT(firstname, lastname, reservationstatus)LIKE '%".$

。。。当我尝试它时，它会显示所有超过10的待定预订
那是因为当你打第二，第三。。。页面（从第1页导航后，$\u POST
数组将为空，即不会设置$\u POST['search']
，这就是为什么否则{…}
部分代码将在每次导航到第2、第3、。。。页。由于您没有随表单发送任何敏感数据，请在表单的方法属性中使用GET
而不是POST
，如下所示：
<form action="..." method="get">
if (isset($_GET['search'])) {
$valueToSearch = $_GET['valueToSearch'];
...
随后，您需要在每个分页链接中附加该搜索查询，以便在从一页跳到另一页时可以使用该搜索查询
// your code
<?php
for($page=1;$page<=$number_of_pages;$page++)
{
echo "<a id='pagingLink' href='adminControl.php?page=" . $page . "&valueToSearch=". urlencode($_GET['valueToSearch']) ."&search'>" . $page . "</a>";
}
?>
// your code
//您的代码
//你的代码
dude它正在工作，但我想是你不小心把$search而不是$valueToSearch放到了搜索中。你在考验我吗。非常感谢。你能纠正它吗？因为其他人可能需要它。echo“@Red啊，你说得对。我已经更新了我的答案，并对代码做了足够的修改。
