Display custom error message in login

I want to implement a simple login with PHP. But, also I want to customize the error message when the login is incorrect, for example display a error message in red color.
Login.php
<form id="frmlogin" name="frmlogin" method="POST" action="validarUsuario.php">
<p><input type="text" name="usuario" id="usuario" class="required" maxlength="50" placeholder="Nombre Usuario"></p>
<p><input type="password" name="password" id="password" class="required" maxlength="50" placeholder="Password"></p>
<p id=error> </p>
<p class="submit"><input type="submit" name="commit" value="Login"></p>
</form>
validarUsuario.php
<?php
include("connection.php");
conectar_bd();
$usr = $_POST['usuario'];
$pw = md5($_POST['password']);
$sql = "SELECT usr FROM Client WHERE usr = '$usr'AND password ='$pw'";
$result = mysql_query($sql, $con);
if ($fila = mysql_fetch_array($result)) {
header('Location: menuclient.php');
} else {
/* How customize my message error */
}
?>
In the Login.php file, when the username or password are not correct, i want to display, for example, in id=error : "Login Incorrect" in red.
I dont know if I can do it with php.
Thanks for your help.

You can use session. Try following way.
Login.php
<?php
session_start();
if($_SESSON['error']): ?>
<span>Error : <?php echo $_SESSION['errorMsg']; ?></span>
<?php endif; ?>
<form id="frmlogin" name="frmlogin" method="POST" action="validarUsuario.php">
<p><input type="text" name="usuario" id="usuario" class="required" maxlength="50" placeholder="Nombre Usuario"></p>
<p><input type="password" name="password" id="password" class="required" maxlength="50" placeholder="Password"></p>
<p id=error> </p>
<p class="submit"><input type="submit" name="commit" value="Login"></p>
</form>
validarUsuario.php
<?php
session_start();
include("connection.php");
conectar_bd();
$usr = $_POST['usuario'];
$pw = md5($_POST['password']);
$sql = "SELECT usr FROM Client WHERE usr = '$usr'AND password ='$pw'";
$result=mysql_query($sql,$con);
if( $fila=mysql_fetch_array($result) )
{
header('Location: menuclient.php');
}
else {
$_SESSION['errorMsg'] = "Wrong username or Password";
$_SESSION['error'] = true;
header('Location: Login.php');
}
?>

This is the mail script which sends me the email
<?php
/* Set e-mail recipient */
$myemail = "**MYEMAIL**";
/* Check all form inputs using check_input function */
$fname = check_input($_POST['fname'], "Enter your first name");
$lname = check_input($_POST['lname'], "Enter your last name");
$email = check_input($_POST['email']);
$phone = check_input($_POST['phone']);
$resort = check_input($_POST['resort']);
$amount = check_input($_POST['amount']);
$call = check_input($_POST['call']);
/* If e-mail is not valid show error message */
if (!preg_match("/([\w\-]+\#[\w\-]+\.[\w\-]+)/", $email))
{
show_error("E-mail address not valid");
}
/* If URL is not valid set $website to empty */
if (!preg_match("/^(https?:\/\/+[\w\-]+\.[\w\-]+)/i", $website))
{
$website = '';
}
/* Let's prepare the message for the e-mail */
$message = "Hello!
Your contact form has been submitted by:
First Name : $fname
Last Name : $lname
E-mail: $email
Phone : $phone
Resort: $resort
Amount: $amount
Call : $call
End of message
";
/* Send the message using mail() function */
mail($myemail, $subject, $message);
/* Redirect visitor to the thank you page */
header('Location: index.html');
exit();
/* Functions we used */
function check_input($data, $problem='')
{
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
if ($problem && strlen($data) == 0)
{
show_error($problem);
}
return $data;
}
function show_error($myError)
{
?>
if (strtolower($_POST['code']) != 'mycode') {die('Wrong access code');}
<html>
<body>
<b>Please correct the following error:</b><br />
<?php echo $myError; ?>
</body>
</html>
<?php
exit();
}
?>
Here is the online url of the page http://timesharesgroup.com/sell/index.html

you can add this code to your script after all the validation is done:
$text = "$fname\n$lname\n$email\n$phone\n$resort\n$amount\n$call\n\n";
file_put_contents('file.txt', $text, FILE_APPEND);
OR even better csv file:
$fields = array($fname,$lname,$email,$phone,$resort,$amount,$call);
$fp = fopen('file.csv', 'a');
fputcsv($fp, $fields);
fclose($fp);

php ajax one page contact form

i am working on one page ajax contactform . I want to send an email with PHP without leaving my page and now i'm completely lost. I have no idea why its not working
i'll show you my contact form. thank you for help in advance. Here is the form ..
html code
<article class="panel" style="background:url(img/cover/bg_panel_3.jpg); background-size:cover;" full-screen>
<div style="padding-top:80px;">
<div class="row text-center centered">
<div id="contact-form">

<div class="medium primary btn pretty-btn">
<input name="submit" class="subbutton" type="submit" value="Send" />
</div>
<input type="hidden" name="submitted" id="submitted" value="true" />
</form>
<?php } ?>
<!-- End #contact -->
</div>
</div>
</div>
</article>
**js code **
$(document).ready(function() {
$('form#contact-us').submit(function() {
$('form#contact-us .error').remove();
var hasError = false;
});
if(!hasError) {
var formInput = $(this).serialize();
alert(formInput);
$.post("contact-us.php",formInput, function(data){
$('form#contact-us').slideUp("fast", function() {
$(this).before('<p class="tick fg-white sans"><strong>Thanks!</strong> Your email has been delivered. !</p>' );
});
});
}
return false;
});
});
PHP Code
//If the form is submitted
if(isset($_POST['submitted'])) {
$name = trim($_POST['contactName']);
$email = trim($_POST['email']);
$num = trim($_POST['num']);
$subject = trim($_POST['subj']);
$comments = trim($_POST['comments']);
$formcontent=" From : $name \n Email : $email \n Subject : $subj \n Phone number : $number \n \n Message : $message";
$recipient = "example#mail.com";
$subject = "Contact Form Query Received";
$mailheader = "From: $email \r\n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error encountered! Please try again or write directly to the mentioned email address.");
// set our boolean completion value to TRUE
$emailSent = true;
}

I suspect your problem is this extra }); in your code which is stopping the $.post(...) call from even being called. A quick lint of your JS shows this up, as does careful reading.
var hasError = false;
======> }); <====== remove this extra stuff.
if(!hasError) {

How to return to the previous page after a submit form with php?

I have a form in html whose "action" attribute calls a contact.php file. The problem is that after I submit the form, the file that is visible is a blank page with the address contact.php and I want to see again the form of the main page.
HTML:
<form id="myForm" action="php-contact/contact.php"
method="post" class="contact_form" autocomplete="off"
role="form">
<div class="form-group">
<label for="input-subject">subject</label>
<input name="subject" type="text" class="form-control" id="subject" placeholder="your subject" maxlength="20"/>
</div>
<div class="form-group">
<label for="input-name">name</label>
<input name="name" type="text" class="form-control" id="name" placeholder="your name" maxlength="20"/>
</div>
<div class="form-group">
<label for="input-email">email address</label>
<input name="email" type="text" class="form-control" id="email" placeholder="your email" maxlength="40"/>
</div>
<div class="form-group" >
<label for="input-message">message</label>
<textarea name="message" cols="10" rows="10" class="form-control" id="comment" ></textarea>
</div>
<button name="myFormSubmitted" type="submit" class="btn btn-primary btn-lg btn-block">send</button>
</form>
PHP:
<?php
$name = $_POST['name'];
$email = $_POST['email'];
$subject = $_POST['subject'];
$message = $_POST['message'];
$to = "pep.g#gmail.com";
$message = '
name: '.$name.'
email: '.$email.'
message: '.$message.'
';
$headers = 'From: pep.website#website.com';
if (
mail($to, $subject, $message, $headers)
)
echo"<script>alert('message send succesfully')</script>";
else
echo"<script>alert('message not send')</script>";
?>

Use either $_SERVER["HTTP_REFERER"] or use a hidden field on the form with the url of the current page:
<form action="myAction.php">
<input type="hidden" name="destination" value="<?php echo $_SERVER["REQUEST_URI"]; ?>"/>
<!-- other form inputs -->
<input type="submit"/>
</form>
myAction.php
<?php
/* Do work */
if(isset($_REQUEST["destination"])){
header("Location: {$_REQUEST["destination"]}");
}else if(isset($_SERVER["HTTP_REFERER"])){
header("Location: {$_SERVER["HTTP_REFERER"]}");
}else{
/* some fallback, maybe redirect to index.php */
}
And then even then you should have fallbacks in case for some reason the client isn't respecting HTTP redirects, like some redirect javascript, a meta redirect and a link to the destination.

Add a JS redirect after your alert then
echo "<script>
alert('message sent succesfully');
window.history.go(-1);
</script>";

In your contact.php file, just use something like at the end of the PHP code:
header("location:yourfilenamehere.php");
This will redirect back to whatever page you specify.

You could do two things...
1) Have your php logic in the form file and submit to that file. On the top of the file, put something like:
if(isset($_POST['name'])) {
// your sending logic
}
followed by your form.
2) use the header() function to redirect to your form.
header("Location: form.html");

I feel pretty bad about posting this answer as it is just concatenating two other SO answers.
First part
Charlie74's answer on this page
// add the message you want to show to the user
header("Location: yourfilenamehere.php?alertmsg=message+send+succesfully");
exit();
Second part check for the alertmsg name in the query string
See SO post for getParameterByName:
function getParameterByName(name) {
name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
results = regex.exec(location.search);
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}
in the page you are redirecting call the getParameterByName function:
<script>
var msg = getParameterByName('alertmsg');
if (alertmsg.length > 0) {
alert(msg);
}
</script>
