使用Ajax请求的数据为什么保存不到数据库中?后台用php写,各位大神支个招
<br /><?php<br /> if(isset($_GET['content'])){<br /> //从请求URL地址中获取参数<br /> $view_name=$_GET["name"];<br /> $view_content=$_GET["content"];<br /> $view_time=$_GET["time"];<br /> $linkview=mysqli_connect("localhost", "root", "xxxxxxx", "wordstv") or die("数据库连接失败:".mysql_errno());<br /> $queryview="insert into wordstv_user_view (user_name,user_content,time,) values ('".$view_name."','".$view_content."','".$view_time."')";<br /> [email protected]_query($linkview, $queryview);<br /> if($resultview){<br /> echo $view_name."&&&".$view_content."&&&".$view_time;<br /> }<br /> mysqli_close($linkview);<br /> }<br />?><br />
------解决思路----------------------
先确定ajax提交的数据是否正确获取。
在php 最前加
$data = $_REQUEST;
file_get_contents('test.log', json_encode($data), true);
看看能否获取到数据,如果可以,再在入库的语句中找问题。
否则在js ajax提交的语句中找问题。
[email protected]_query($linkview, $queryview) or die(mysql_error()); 这里也加上看看。
------解决思路----------------------
content 通常表示正文,一般比较大
如果整个传送的数据可能超过 get 方式的 2K 限制的话,应使用 post 方式
从减少信息泄露的角度上看,使用 POST 方式也是较为妥当的
你直接将传入的数据入库了,如果传入的数据中含有特殊字符,就将导致插入失败
你只在插入成功时输出了信息,却没在插入失败时做出响应
无论是操作成功与失败都应有信息返回,这样才方便判断问题的所在

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
