this is a registration validation script. in my registration form there are two email and password filelds.second fields are for confirmation.i want to check weather user typed same information in that both field.if i want to do that in this script should i use another if statement? or i should use else if? i am confused about that step...
add additional conditions to your second if statement. eg
if($email=='' || $email != $email2){
...
Just add simple checks. I wouldn't combine the check with the general password check - as I can imagine you would like to tell the user what went wrong exactly .
if ($password1 !== $password2) {
// Add an specific error saying the passwords do not match.
}
I would replace the user of loose errors to an array like:
$aErrors = array();
if ($password1 !== $password2) {
$aErrors[] = 'Another specific error!';
}
if (empty($password1) || empty($password2)) {
$aErrors[] = 'Another specific error';
}
if (empty($aErrors)) {
// Process the form!
}
There are lots of issues with your code.
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) {
}
so.....
$errors = array();
so you'd check something like..
if ($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
}
I'll also suggest to sanitise the $_POST values before you use them in your queries. I hope it helps.
I think you mean to do this:
$yourname = $_POST['yourname'];
$email = $_POST['email'];
$email2 = $_POST['email2'];
$password = $_POST['password'];
$password2 = $_POST['password2'];
$country = $_POST['country'];
Second this make use of an errors array:
$errors = array();
Third use nested ifs(just a suggestion)
if (!empty($_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 {
$errors[] = '<font color="red">Please provide a password.</font>';
}
Some comments:
Some sample code...:
// Simple sanitize function, complete it
function sanitize_input ($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
