我正在编写一个脚本,检查数据库中是否存在电子邮件 barn_users
,以重置密码。如果电子邮件不存在,则不会生成令牌/代码并将其存储在数据库中。一切都很正常,直到我输入了一封不在系统中的电子邮件。错误为“在系统中找不到电子邮件”的else语句不会触发。我为什么不明白?
$sql_1 = "SELECT * FROM password_reset WHERE email='$email'";
$sql_2 = "SELECT * FROM barn_users WHERE email='$email'";
$generate = mysqli_query($conn, $sql_1);
$searchEmail = mysqli_query($conn, $sql_2);
while($row = mysqli_fetch_array($searchEmail)) {
if(mysqli_num_rows($searchEmail) > 0) {
if (mysqli_num_rows($generate) > 1) {
} else if (mysqli_num_rows($generate) < 1) {
$sql = "INSERT INTO password_reset (code,email) VALUES ('$code','$email')";
} else {
$sql = "UPDATE password_reset SET code='$code' WHERE email='$email'";
}
if ($conn->query($sql) == TRUE) {
echo "Reset password has been emailed to you";
} else {
}
} else {
echo "Could not find email in the system.";
}
}

感谢@bleat和@ivan的评论。你的回答都有帮助。这是工作结果。在循环外使一个变量为假,给了我想要的答案。
