我有一个 HTML 表单，用于将信息存储在 MySQL 数据库上。有用!但我想要一个唯一可以完成所有 PHP 扩展的文件。我在单击按钮时填充了数据库，但转而部署 PHP 文件，我不希望发生这种情况。
这是我的 HTML 代码:
<html>
<head></head>
<body>
<form id="form" name="form" action="insert.php" method="POST">
<label id="lbluser">Name:</label>
<input type="text" name="name" id="name" /><br/>
<label id="lbllastaname">Lastname:</label>
<input type="text" name="lstname" id="lstname" /><br/>
<label id="lblmail">E-mail:</label>
<input type="text" name="email" id="email" /><br/>
<label id="lblpassword">Password:</label>
<input type="password" name="password" id="password" /><br/>
<label id="lblpassword">Repeat password:</label>
<input type="password" name="passwordr" id="passwordr" /><br/>
<button type=”submit” name=”button” value=”insert”>OK</button>
</form>
</body>
</html>
这是我的 PHP 代码:
<?php
$mysqli = mysqli_connect("localhost", "user", "12345", "own_bd");
if (mysqli_connect_errno()) {
printf("Problem with connection: %s\n", mysqli_connect_error());
exit();
}
else {
$var_name = mysqli_real_escape_string($mysqli, $_POST['name']);
$var_lst = mysqli_real_escape_string($mysqli, $_POST['lstname']);
$var_mail = mysqli_real_escape_string($mysqli, $_POST['email']);
$var_pwd = mysqli_real_escape_string($mysqli, $_POST['password']);
$var_pwdr = mysqli_real_escape_string($mysqli, $_POST['passwordr']);
$sql = "INSERT INTO users_tbl (Name,Lastname,Mail,Pwd,PwdR) VALUES ('".$var_name."','".$var_lst."','".$var_mail."','".$var_pwd."','".$var_pwdr."')";
$res = mysqli_query($mysqli, $sql);
if ($res === TRUE) {
echo "User added.";
}
else {
printf("Error: %s\n", mysqli_error($mysqli));
}
mysqli_close($mysqli);
}
?>
我该怎么做？希望您的帮助。
isset 函数在此脚本中对我不起作用，但如果我尝试此代码，它会起作用!
<form action="" method="post">
<input type="submit" value="Click" name="addImg" />
</form>
<?
if (isset($_POST['addImg'])) {echo "haaallloooo";}
?>
救命!!!
最佳答案
如果我理解你的要求，HTML 和 PHP 可以在同一页面上。
请记住，更好的做法是将 processnig 代码放在文件顶部。
<?php
if(isset($_POST['button'])){
$mysqli = mysqli_connect("localhost", "user", "12345", "own_bd");
if (mysqli_connect_errno()) {
printf("Problem with connection: %s\n", mysqli_connect_error());
exit();
}
else {
$var_name = mysqli_real_escape_string($mysqli, $_POST['name']);
$var_lst = mysqli_real_escape_string($mysqli, $_POST['lstname']);
$var_mail = mysqli_real_escape_string($mysqli, $_POST['email']);
$var_pwd = mysqli_real_escape_string($mysqli, $_POST['password']);
$var_pwdr = mysqli_real_escape_string($mysqli, $_POST['passwordr']);
$sql = "INSERT INTO users_tbl (Name,Lastname,Mail,Pwd,PwdR) VALUES ('".$var_name."','".$var_lst."','".$var_mail."','".$var_pwd."','".$var_pwdr."')";
$res = mysqli_query($mysqli, $sql);
if ($res === TRUE) {
echo "User added.";
exit();
}
else {
printf("Error: %s\n", mysqli_error($mysqli));
}
}
mysqli_close($mysqli);
}
?>
