這是一個注冊驗證腳本。 在我的注冊表單中有兩個 email 和密碼 filelds.second 字段用於確認。我想檢查天氣用戶在這兩個字段中輸入的相同信息。如果我想在這個腳本中這樣做,我應該使用另一個 if 語句嗎? 或者我應該使用 else if? 我對那一步感到困惑...
在第二個 if 語句中添加附加條件。 例如
if($email=='' || $email != $email2){
...
只需添加簡單的檢查。 我不會將檢查與一般密碼檢查結合起來——我可以想象你想告訴用戶究竟出了什么問題。
if ($password1 !== $password2) {
// Add an specific error saying the passwords do not match.
}
我會將松散錯誤的用戶替換為如下數組:
$aErrors = array();
if ($password1 !== $password2) {
$aErrors[] = 'Another specific error!';
}
if (empty($password1) || empty($password2)) {
$aErrors[] = 'Another specific error';
}
if (empty($aErrors)) {
// Process the form!
}
你的代碼有很多問題。
1. You are assinging $_POST['key'] = $somevalue, while I think you mean $somevar = $_POST['key']
2. Use an array for all error messages as it'll make your life a bit easier ..
3. To compare password use something like
if ($password1 !== $password2) {
}
所以.....
$errors = array();
所以你會檢查類似..
if ($password1 !== $password2) {
$errors[] = 'Password dont match';
}
if(count($errors) > 0) { //if there are errors
foreach($errors as $err) {
echo $err.' <br />';
}
} else {
// whatever you want to do if no error
}
我還建議在查詢中使用 $_POST 值之前對其進行清理。 我希望它有所幫助。
我認為你的意思是這樣做:
$yourname = $_POST['yourname'];
$email = $_POST['email'];
$email2 = $_POST['email2'];
$password = $_POST['password'];
$password2 = $_POST['password2'];
$country = $_POST['country'];
其次,這使用了一個錯誤數組:
$errors = array();
第三次使用嵌套 ifs(只是一個建議)
if (!empty($_POST['password1'])) {
if ($_POST['password1'] != $_POST['password2']) {
$errors[] = '<font color="red">The 2 passwords you have entered do not match.</font>';
} else {
$password = $_POST['password1'];
}
} else {
$errors[] = '<font color="red">Please provide a password.</font>';
}
一些評論:
一些示例代碼...:
// Simple sanitize function, complete it
function sanitize_input ($inputstr) {
return trim(mysql_real_escape_string($inputstr));
}
if (isset ($_POST['Registerme']) {
// array of error messages to report
$error_messages = array();
$isvalid = true;
// Assignment
$yourname = sanitize_input ($_POST['yourname']);
$email = sanitize_input ($_POST['email']);
$email2 = sanitize_input ($_POST['email2']);
$password = sanitize_input ($_POST['password']);
$password2 = sanitize_input ($_POST['password2']);
$country = sanitize_input ($_POST['country']);
// Validation
if (empty ($yourname)) {
$error_messages[] = "You must provide an username";
}
if (empty ($password)) {
$error_messages[] = "You must provide a password.";
}
elseif ($password !== $password2) {
$error_messages[] = "Passwords do not match.";
}
// Same for email, you caught the idea
// Finally, execute mysql code if all ok
if (empty($error_messages)) {
// Execute mysql code
isvalid = true;
}
}
// After form processing, use isvalid which is false if there are errors
// and the error_messages array to report errors
