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.

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;
}
?>
<html>
<style>
.body {
text-align: center;
padding: 20px;
}
</style>
<body>
<h1 style="text-align:center; padding: 20px">Bike listings</h1>
<?php
$listings = $name . "<br>" . $phone . "<br>" . $email . "<br>" . $serial . "<br>" . $type . "<br>" . $description;
echo "<div style='text-align:center; padding: 50px'>$listings</div>";

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 = '';

if( $_SERVER['REQUEST_METHOD']=='POST' && isset(
$_POST['sName'],
$_POST['sNum'],

$_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}/';

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' : '';

$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

Unable to store data in the database

I am creating a PHP registration form using AJAX, the below code that I have pasted isn't working properly. I am literally new to this AJAX concept
When I click the register button it won't respond and do anything, and even in the database the values are not getting stored. I have searched a lot for this AJAX concept.
But I don't seem to get the result what I want. Please, can any one help me. Where am I actually doing the wrong thing? Thanks in advance!

Hi everyone i really really need you people help.
Actually i creating a registration form where users can register their details.
The registration form is absolutely working well. and even the users when logged in thats also
working good, but now when the users tries to update his details, such as name, username is getting updated
but when the user tries to update his image then the problem arises, except image the remaining portion
is getting updated when it comes to the image, the image is not getting update, please guys its my humble request
to all the people who are viewing my question please help me to solve this issue, i'm trying to fix this from four
days but im unable to do so please please please please help me i really need your help please
You should add enctype="multipart/form-data" attribute into form element:
<form method="POST" action="" enctype="multipart/form-data">
While editing edit image operation,
you should put your update sql query with if else condition.
So, basically,
if(empty($image_file_name)){
//query without image column
$sql = "update `users` set name='$name',username='$username',
email='$email', Date_of_birth='$DateOfBirth', department='$department',
age='$age' where userid ='$id'" ;
//do not forget to execute query here with mysqli_query
}
if(!empty($image_file_name)){
//query with image column
$sql = "update `users` set name='$name',username='$username',
email='$email', Date_of_birth='$DateOfBirth', department='$department',age='$age',
image_name='$image_file_name' where userid ='$id'" ;
//do not forget to execute query here with mysqli_query
}
Also make sure we can not prefetch value like textbox, in input type='file', but yes, you can preview the already uploaded image with img tag.
So, instead
<input type='file' value='<?php echo $filename; ?>' <!--do not use this-->
You should use,
<input type='file'>
<img src='your_already_uploaded_file_path' height='50px' width='50px'> <!--change height width as you wish-->
Also, make sure, you are missing enctype="multipart/form-data", with your form tag. So, do not forget to add this attribute with your form tag. This attribute is must while working with uploading files.
