How do i pass variables to another page in php? - php

I have moved over the validation to the bikeInfo.php file. Not much changes have been made to the code, but not sure why the validation is not being processed... appreciate the help!
<?php
$nameErr = $phoneErr = $emailErr = $sErr = $errorMsg = "";
$name = $phone = $email = $serial = $type = $formSubmit = $description = "";
?>
<head>
<title>Register your bikes!</title>

<style>
body {
margin-left: auto;
margin-right: auto;
text-align: center;
padding: 8px;
}
div.sellerInfo {
position: relative;
top: 50px;
}
.error {
position: absolute;
color: red;
}
</style>
<html>
<body>
<form method="post" action="bikeInfo.php">

<span class="error">* <?php echo $sErr;?></span>
<br><br>

<br><br>
<input type="submit" name="formSubmit" value="Submit"/>
</div><br><br><br>
</form>
</body>
</html>
This is my bikeInfo.php file which does validation and displaying of the submitted values. Not sure am i suppose to separate them...
<?php
//set to empty strings
$name = $phone = $email = $serial = $type = $formSubmit = $description = "";
$nameErr = $phoneErr = $emailErr = $sErr = $errorMsg = "";
if (isset($_POST["formSubmit"]))
{
if (empty($_POST["sName"]))
{
$nameErr = "Name is required";
} else {
$name = test_input($_POST['sName']);
}
//validate phone number
if (empty($_POST["sNum"]))
{
$phoneErr = "Phone number is required";
} else {
$phone = test_input($_POST['sNum']);
if (!is_numeric($phone)) //check for letters
{
$phoneErr = "No letters allowed";
}
}
//validate email
if (empty($_POST["sEmail"]))
{
$emailErr = "Email is required";
} else {
$email = test_input($_POST['sEmail']);
if (!filter_var($email, FILTER_VALIDATE_EMAIL))
{
$emailErr = "Invalid email format";
}
}
//validate serial
if (empty($_POST["serial"]))
{
$sErr = "Serial number is required";
} else {
$serial = test_input($_POST['serial']);
//determing the pattern of the serial no. yy-nnnn-cc
if (!preg_match("/[0-9][0-9]\-\d{3}\-[a-z]{2}/", $serial))
{
$sErr = "Format is yy-nnn-cc";
}
}
//validate type
if (empty($_POST["type"]))
{
$errorMsg = "Type is required";
} else {
$type = test_input($_POST["type"]);
}
}
function test_input($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
?>

I had a little play about refactoring the code so that you could use a single page to perform both the validation and display. Perhaps it may be of use.
<?php
error_reporting( E_ALL );
$errors=array();
$nameErr = $phoneErr = $emailErr = $sErr = $errorMsg = '';
$sName = $sNum = $sEmail = $serial = $type = $description = '';
if( $_SERVER['REQUEST_METHOD']=='POST' && isset(
$_POST['sName'],
$_POST['sNum'],
$_POST['sEmail'],
$_POST['serial'],
$_POST['type']
)){
# modified to accept uppercase chars at end and limited to 2 integers at atart
$pttn='/[0-9]{2}\-\d{3}\-[a-zA-Z]{2}/';
# config to filter POST vars
$args=array(
'sName' => FILTER_SANITIZE_STRING,
'sNum' => FILTER_SANITIZE_STRING,
'sEmail' => FILTER_SANITIZE_EMAIL,
'serial' => FILTER_SANITIZE_STRING,
'type' => FILTER_SANITIZE_STRING,
'description' => FILTER_SANITIZE_STRING
);
# test for unaccounted POST fields - possibly malicious
foreach( $_POST as $field => $value ){
if( !in_array( $field, array_keys( $args ) ) ){
$errors[]=sprintf('Unknown field %s',$field);
}
}
if( empty( $errors ) ){
# rebuild the POST array with only filtered values
$_POST=filter_input_array( INPUT_POST, $args );
# extract known values from POST array into variables
extract( $_POST );
#error messages
$nameErr=empty( $sName ) ? 'Name is required' : '';
$phoneErr=empty( $sNum ) ? 'Phone number is required' : '';
$emailErr=empty( $sEmail ) ? 'Email is required' : '';
$sErr=empty( $serial ) ? 'Serial number is required' : '';
$errorMsg=empty( $type ) ? 'Type is required' : '';
# Validate particular variables
$sEmail=filter_var( $sEmail, FILTER_VALIDATE_EMAIL );
# to filter the phone number might remove leading zero and thus appear invalid
# possibly reassign error message variables
if( !preg_match( $pttn, $serial ) )$sErr='Invalid Serial. The format is: yy-nnn-cc';
if( !$sEmail )$emailErr='Invalid email format';
if( !$sNum )$phoneErr='Invalid phone number. No letters allowed!';
# save to database, email somewhere, write text etc etc

PHP Validation. It won't go to display page

I'm new to PHP and the validation. I have been asked by my lecturer to make a form with session and validation.I have 3 php pages such as pbt1.php , pbt2.php and validation.php After all validated, it will go to display page. However, it seems like it only stopped at validation page [validation.php]. I need someone to check if my codes are correct or wrong too.
pbt1.php

<?php
if(isset($_SESSION['pbt1']))

Depending on the PHP version (>= 7.0) you are using, you could change
<?php echo isset($nameError)?$nameError :'';?>
to
<?php echo $nameError ?? ''; ?>
As for HTML, you might want to change
<form name = "pbt1" method = "post" action = "validation.php">
to
<form name="pbt1" method="post" action="validation.php">
That doesn't change the outcome, but easier to read.
What's next...
$name = $_POST['name'];
if(isset($name) && empty($name))
{
could be changed into
if (array_key_exists('name', $_POST) && trim($_POST['name']) === '') {
Looks like more code, but the intention of the if becomes more clear.
As far as this one goes
if(isset($_SESSION['pbt1']))
{
$nameError = $_SESSION['pbt1']['nameError'];
$numberError = $_SESSION['pbt1']['numberError'];
$cityError = $_SESSION['pbt1']['cityError'];
$addressError = $_SESSION['pbt1']['addressError'];
$zipcodeError = $_SESSION['pbt1']['zipcodeError'];
$dateError = $_SESSION['pbt1']['dateError'];
}
...don't trust your session. I would change it to
if (array_key_exists('pbt1', $_SESSION)) {
$nameError = $_SESSION['pbt1']['nameError'] ?? '';
$numberError = $_SESSION['pbt1']['numberError'] ?? '';
$cityError = $_SESSION['pbt1']['cityError'] ?? '';
$addressError = $_SESSION['pbt1']['addressError'] ?? '';
$zipcodeError = $_SESSION['pbt1']['zipcodeError'] ?? '';
$dateError = $_SESSION['pbt1']['dateError'] ?? '';
}
This one
$_SESSION['Userdata'] = ['name'=>$name ,'phonenumber'=>$phonenumber,'address'=>$address,'city'=>$city,
'zipcode'=>$zipcode,'gender'=>$gender,'date'=>$date ];
I would change to
$_SESSION['Userdata'] = [
'name' => $_POST['name'] ?? '',
'phonenumber' => $_POST['phonenumber'] ?? '',
'address'. => $_POST['address'] ?? '',
'city'. => $_POST['city'] ?? '',
'zipcode' => $_POST['zipcode'] ?? '',
'gender'. => $_POST['gender'] ?? '',
'date'. => $_POST['date'] ?? '',
];
Since validation.php is pure PHP, get rid of
?>
at the end of the file.
What else...
At the beginning of validation.php, make sure you clear out $_SESSION['pbt1'] aka.
unset($_SESSION['pbt1']);
Instead of doing header('location:pbt1.php'); after every issue, remove header('location:pbt1.php'); from every individual if block and put it at the end, as in
if(isset($date) && empty($date)) {
$_SESSION['pbt1']['dateError'] = "Error, select the date";
// header('location:pbt1.php');
}
if (array_key_exists('pbt1', $_SESSION)) {
header('location:pbt1.php');
exit;
}
$_SESSION['Userdata'] = ...
that way you don't have to fix every error by itself and you show them all at once.

Hi, guys I have only one small issue please help me, I have a registration form with the various input,
my problem is if I give blank space to the name input field and then if I give submit then it should
show any error that no space are allowed
i.e., their should be only letters except that it should not accept any numbers special characters and other thing please.
Can any one help me in this please ?
This line if (!preg_match("/^[a-zA-Z ]*$/",$name)) { must be like this:
if (!preg_match("/^[a-zA-Z]*$/",$name)) {
Explanation:
Your regex has a space at the end. Removing it will solve your problem.

PHP form-calling function failing to work properly

I have my index.php form and if a valid student name and student number are entered I'd like "Student name and number are valid." to be echoed.
I have validated the student names and student numbers. However, even when entering a valid student name and student number the message echoed is "The information you have entered is not valid. Please enter your information again."
I'm calling the function validateStudent but I must be calling it in the wrong place or incorrectly. This function is called towards the end of the PHP scrip and just before the HTML starts. Thank you.

Your code has a logical error:
if (isset ($_POST[$studentname], $_POST[$studentnumber])) {
validateStudent($_POST['$studentname'], $_POST['$studentnumber']);
echo 'Student name and number are valid.\n';
}
else {
echo '<p style="color: red; text-align: center; font-size: 15px; font-weight: bold;">**The information you have entered is not valid. Please enter your information again.**</p>';
}
your code should be:
if (isset ($_POST['studentname'], $_POST['studentnumber'])) {
if (validateStudent($_POST['studentname'], $_POST['studentnumber'])){
echo 'Student name and number are valid.\n';
}
else {
echo '<p style="color: red; text-align: center; font-size: 15px; font-weight: bold;">**The information you have entered is not valid. Please enter your information again.**</p>';
}
}
also you need a form to post your variables studentname and studentnumer like:
<form method="post">
<input type="text" name="studentname"/>
<input type="text" name="studentnumber"/>
<input type="submit" name="submit"/>
</form>
Your output is because your variables $_POST['studentname'] and $_POST['studentnumber'] are not set.
