所以我是php的新手，我在reg.php文件中有此表格
OpcoesProdutoDialogo opcProduto = OpcoesProdutoDialogo.criar(itemPedido);
opcProduto.show(getFragmentManager(), "opc_produto_editar");
opcProduto.setOnDismissListener(d->{
adapterItens.notifyItemChanged(posicao);
});
我有signup.php，其中包含注册代码
<form method="post" action="scripts/signup.php" class="ui form"">
<div class="field">
<label>UserName</label>
<input type="text" name="username" placeholder="Choose a unique UserName">
</div>
<div class="field">
<label>Name</label>
<input type="text" name="name" placeholder="Name" required>
</div>
<div class="field">
<label>Address</label>
<input type="text" name="address" placeholder="Address" required>
</div>
<div class="field">
<label>E-mail</label>
<input type="email" name="email" placeholder="Your E-Mail" required>
</div>
<div class="field">
<label>Password</label>
<input type="password" name="password" placeholder="Your Password" required>
</div>
<div class="field">
<label>Confirm Password</label>
<input type="password" name="password2" placeholder="Confirm Password" required>
</div>
<button type="submit" name="submit" class="ui big inverted red button" value="submit">Register</button>
<br/>
<br/>
</form>
dbh.php仅包含变量，并且只为db设置，主行是
<?php
if (isset($_POST['submit'])) {
include_once 'dbh.php';
$username = mysqli_escape_string($conn, $_POST['username']);
$name = mysqli_escape_string($conn, $_POST['name']);
$address = mysqli_escape_string($conn, $_POST['address']);
$email = mysqli_escape_string($conn, $_POST['email']);
$password = mysqli_escape_string($conn, $_POST['password']);
// cccheck if username is already in db
$query = "SELECT * FROM users WHERE username='$username'";
$res = mysqli_query($conn, $query);
$rescheck = mysqli_num_rows($res);
//if the query returns a row or multiple
if ($rescheck > 0) {
header("Location: ../reg.php?reg=usernamesame");
exit();
} else {
//password hashing
$hashed_password = password_hash($password, PASSWORD_DEFAULT);
//write user too db
$sql_insert = "INSERT INTO users(username, name1, address, email, pass)VALUES ('$username','$name','$address','$email','$hashed_password');";
$results = mysqli_query($conn, $sql_insert);
echo $results;
header("Location: ../reg.php?reg=succcess");
exit();
}
} else {
header("Location: ../reg.php?reg=Error");
exit();
}
问题是，当我提交表单时，我收到成功消息，但是在进一步检查时，用户并未添加到数据库中。
任何帮助将不胜感激
抱歉，这是我的全部错，我没有将通行证设置为接收如此大的字符串。谢谢大家的帮助。

注释的下面两行，这是对结果和标头重定向的回显。然后回显$ sql_insert以查看已执行的sql查询。提交表单后，获取该查询并在phpmyadmin sql query部分中运行它。如果查询中有任何错误，您将轻松找到它。同样，使用小度量标准来解决您的问题。
//write user too db
$sql_insert = "INSERT INTO users(username, name1, address, email, pass)VALUES ('$username','$name','$address','$email','$hashed_password');";
$results = mysqli_query($conn, $sql_insert);
echo $sql_insert;
//echo $results;
//header("Location: ../reg.php?reg=succcess");
exit();

嗨，您可以像这样修改脚本php：
<?php
if (isset($_POST['submit'])) {
include_once 'dbh.php';
$username = mysqli_escape_string($conn, $_POST['username']);
$name = mysqli_escape_string($conn, $_POST['name']);
$address = mysqli_escape_string($conn, $_POST['address']);
$email = mysqli_escape_string($conn, $_POST['email']);
$password = mysqli_escape_string($conn, $_POST['password']);
// cccheck if username is already in db
$query = "SELECT * FROM users WHERE username='$username'";
$res = mysqli_query($conn, $query);
$rescheck = mysqli_num_rows($res);
//if the query returns a row or multiple
if ($rescheck > 0) {
header("Location: ../reg.php?reg=usernamesame");
exit();
} else {
//password hashing
$hashed_password = password_hash($password, PASSWORD_DEFAULT);
//write user too db
$sql_insert = "INSERT INTO users (username, name1, address, email, pass) VALUES ('$username','$name','$address','$email','$hashed_password');";
$results = mysqli_query($conn, $sql_insert);
echo $results;
header("Location: ../reg.php?reg=succcess");
exit();
}
} else {
header("Location: ../reg.php?reg=Error");
exit();
}

在您的SQL插入语句中，您要用分号关闭VALUES。
将您的声明更改为此：
$sql_insert = "INSERT INTO users(username, name1, address, email, pass)VALUES ('$username','$name','$address','$email','$hashed_password') ";
有关进一步的通知，请出于安全目的使用PDO。

以此方式重写代码。如果有任何错误，它将显示在屏幕上。 而且，当您重定向到另一个页面时，您无需回显结果。
<?php
if (isset($_POST['submit'])) {
include_once 'dbh.php';
$username = mysqli_escape_string($conn, $_POST['username']);
$name = mysqli_escape_string($conn, $_POST['name']);
$address = mysqli_escape_string($conn, $_POST['address']);
$email = mysqli_escape_string($conn, $_POST['email']);
$password = mysqli_escape_string($conn, $_POST['password']);
// cccheck if username is already in db
$query = "SELECT * FROM users WHERE username='$username'";
$res = mysqli_query($conn, $query);
$rescheck = mysqli_num_rows($res);
//if the query returns a row or multiple
if ($rescheck > 0) {
header("Location: ../reg.php?reg=usernamesame");
exit();
} else {
//password hashing
$hashed_password = password_hash($password, PASSWORD_DEFAULT);
//write user too db
$sql_insert = "INSERT INTO users(username, name1, address, email, pass)VALUES ('$username','$name','$address','$email','$hashed_password')";
$results = mysqli_query($conn, $sql_insert) or die(mysqli_error());
echo $results;
header("Location: ../reg.php?reg=succcess");
exit();
}
} else {
header("Location: ../reg.php?reg=Error");
exit();
}
