Question

我有一个包含用户及其电子邮件的数据库，但是无法从代码中添加新用户。我在C：\ xampp \ htdocs中有一个表单，但是当尝试通过该表单添加用户时，没有任何反应。我只能在pma中进行更改。

<?php
$pdo = new PDO('mysql:host=localhost;port=3306;dbname=misc', 
   'fred', 'zap');
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);


<?php
require_once "pdo.php";

if ( isset($_POST['name']) && isset($POST['email']) 
	 && isset($_POST['password'])) {
		$sql = "INSERT INTO users (name, email, password)
				VALUES (:name, :email, :password)"; 
		echo("<pre>\n".$sql."\n</pre>\n");
		$stmt = $pdo->prepare($sql); 
		$stmt->execute(array(
			':name' => $_POST['name'],
			':email' => $_POST['email'],
			':password' => $_POST['password']));
		
}
?>
<html>
<head></head><body>
<p>Add a New User</p>
<form method="post">
	<p>Name:
	<input type="text" name="name" size="40"></p>
	<p>Email:
	<input type="text" name="email"></p>
	<p>Password:
	<input type="password" name="email"</p>
	<p><input type="submit" value="Add New"/></p>
</form>
</body>

Answer 1

签出<input type="password" name="email"。这里是name='password'而不是name="email"。

isset($_POST['password']))返回null，如果条件不满足，则查询不执行>

Answer 2

尝试低于该代码。

 <?php
    //require_once "pdo.php";

    //my own db connection
    $pdo = new PDO (
        'mysql:host=localhost;dbname=misc;charset=utf8', 
        'fred', // username

        'zap' // password
    );


    if ( isset($_POST['name']) && isset($POST['email']) 
         && isset($_POST['password'])) {


    $sql = $pdo->prepare("INSERT INTO users(name, email, password) 
    values(:name, :email, :password) ");
    $sql->execute(array( 

    ':name' => $_POST['name'],
                ':email' => $_POST['email'],
                ':password' => $_POST['password']

    ));
    if(sql){
    echo "success"; 
}else{
echo "failed";
}       
    }
    ?>
    <html>
    <head></head><body>
    <p>Add a New User</p>
    <form method="post">
        <p>Name:
        <input type="text" name="name" id="name" size="40"></p>
        <p>Email:
        <input type="text" name="email" id="email"></p>
        <p>Password:
        <input type="password" name="password"  id="password"></p>
        <p><input type="submit" value="Add New"></p>
    </form>
    </body>

提交的表单不会更改数据库中的值
