php中搜索功能
我是想实现刚刚开始显示所有数据库表的信息,按照输入框查询后,只显示查询到的内容,其余的不出现,怎么改呢,我现在只做到了显示全部信息!!
include("inc/conn.php");
?>
if(!isset($_POST['search'])||trim($_POST['search'])==''){
$_POST['search']='';
}
$find = $_POST['search'];
$result=mysql_query("select * from job where title like '%".$inputkey."%'");
while($myrow=mysql_fetch_array($result)){
?>

回复讨论(解决方案)
表单写错了
改成这样
$inputkey 这个变量是从哪里获取?
你这一行里面没有name 指,php接受的表单值是根据name值接受的。
我们公司的前端写页面的时候也总是这样 不写name值。。。。。。
input 不加name属性,php怎么获取得到?
取值查询也有问题
$inputkey = isset($_POST['inputkey ']) ? $_POST['inputkey '] : '';
$result=mysql_query("select * from job where title like '%".$inputkey."%'");
谢谢各位,问题解决了,最后代码是这样的
include("inc/conn.php");
?>
// if(!isset($_POST['search'])||trim($_POST['search'])==''){
// $_POST['search']='';
// }
// $find = $_POST['search'];
$inputkey = isset($_POST['inputkey']) ? $_POST['inputkey'] : '';
$result=mysql_query("select * from job where title like '%".$inputkey."%'");
while($myrow=mysql_fetch_array($result)){
?>

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
