如何在php中模拟点击按钮

Aug 28, 2018 pm 04:49 PM

本篇文章主要给大家介绍关于如何在PHP中模拟点击提交按钮。下面我们通过具体例子来介绍。

一段代码如下:

<?php  
 session_start();  
  
 require("config.php");  
  
 $db = mysql_connect($dbhost, $dbuser, $dbpassword);  
 mysql_select_db($dbdatabase, $db);  
  
 if($_POST[&#39;submit&#39;]!=""){  
 $username=$_SESSION[username];  
 $city=$_POST[city];  
 $attraction=$_POST[attraction];  
 $imageNum=$_POST[number];  
 $relevance=$_POST[relevance];  
 $sql = "Insert Into vote (username,city,attraction,imageNum,relevance,dateposted) Values(&#39;$username&#39;,&#39;$city&#39;,&#39;$attraction&#39;,&#39;$imageNum&#39;,&#39;$relevance&#39;,NOW())"; 
 $result=mysql_query($sql);  
 echo "";  
 echo "";  
 }  
 ?>
Copy after login

如果我们在上述代码的基础下,想要实现每次评价成功后自动跳到下一张图片的功能即模拟点击下“addButton ”(addButton的功能就是跳到下一张图片)

这种功能该如何实现呢?解决办法如下两点:

1、弹出提示框,然后自动跳转到指定页面,即重定向:

function alertInfor($infor = false, $href = false) {echo <<SCRIPT;}alertInfor("评价成功","next.html");
Copy after login

2、弹出提示框,然后执行js脚本更换图片:将你的addButton函数内容替换掉alert的下一句就行了。不过这段代码必须和你的页面js在同一页面。

本篇文章具有一定的参考价值,希望对有需要的朋友有所帮助。

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
