我这个代码点击提交后的为什么页面显示不存在?
这是两个页面 下面是1.php 提交后跳转到2.php 再跳转到1.php 我用360的浏览器提交后直接显示页面不存在 是怎么回事? 数据库也没有任何东西 我是新手 可能有很多错误 大家帮我看看吧 谢谢
这是1.php
$db = new PDO('mysql:host=localhost;dbname=t1', 'root', '',array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES 'utf8'"));
$rs = $db -> prepare("select * from `baidu`;");
$rs -> execute();
$list = $rs -> fetchAll(PDO::FETCH_ASSOC);
?>
foreach($list as $v){
echo $v['type'].'
';
echo $v['name'].'
';
echo $v['num'].'
';
echo $v['site'].'
';
echo $v['content'].'
';
}
?>
这是2.php
$pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
if($pdo->exec("INSERT INTO baidu(
type,
name,
num,
site,
content
)
VALUES (
'select','name','num','site','content'
)")){
echo "<script>alert('发布成功');location='1.php';</script>";
}
?>

看看地址栏上的网址是什么?
还有,你的站点目录结果及这两个文件所在的位置是怎么样的?

我刚才粗心把那个2.php的文件放到外面了 所以不显示 现在我放到www目录下了 但是数据提交成功后显示不出来刚才提交的内容呢
而且为什么数据库里面不是插入的数据呢 都是name的值呢

因为你2.php的sql没有加$ 写的是常量
$pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
if($pdo->exec("INSERT INTO baidu(
type,
name,
num,
site,
content
)
VALUES (
'select','name','num','site','content'
)")){
echo "<script>alert('发布成功');location='1.php';</script>";
}
你自己插入的就是字符串,当然就是那个结果。你并没有获取表单提交过来的值。
post的值没有传过去 我改成(
'$_POST[select]','$_POST[name]','$_POST[num]','$_POST[site]','$_POST[content]'
)") 怎么还是不行啊

改成这样了 插入的内容还是原来的那些
('$_POST[select]','$_POST[name]','$_POST[num]','$_POST[site]','$_POST[content]')")
在2.php 中 print_r($_POST); 看看结果。
改成下面这样试试看
('{$_POST['select']}','{$_POST['name']}','{$_POST['num']}','{$_POST['site']}','{$_POST['content']}')")
在2.php 中 print_r($_POST); 看看结果。
改成下面这样试试看
('{$_POST['select']}','{$_POST['name']}','{$_POST['num']}','{$_POST['site']}','{$_POST['content']}')")
改成你这样了 还是不行 print_r($_POST);这句话加在echo前面吗 试了一下 什么都没有 我把echo注释掉 只写这一句 怎么还是弹出来提交成功 然后还和原来一样
你这个SQL写法都有问题的。
老老实实拼接SQL语句字符串吧。
在2.php 中 print_r($_POST); 看看结果。
改成下面这样试试看
('{$_POST['select']}','{$_POST['name']}','{$_POST['num']}','{$_POST['site']}','{$_POST['content']}')")

加在首行先看下有不有值。
print_r($_POST);
exit();
$pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
.....

我刚下班 试了一下 还是 不行 和原来一样

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.

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 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 type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.
