PHP - Display A Success Message After Form Is Submitted

I am adding line items in my invoice script, while adding i validate the data. if validation fails, it will display error message with entered data filled in the form. If it clears the validation, data gets submitted to database and displays the same . Here i can add many line items, so this process should keep repeating.

Everything is working fine. But when the form submits it should display error in one place and display the submitted data in other place.

Here is my form

 

<form action="" method="post">
                                        <div class="form-row">
                                            <div class="col-md-4 mb-30">
                                                <label for="validationDefault01">Select Customer</label>
                                            <select name="customer" class="form-control" id="validationDefault01" required>
                                            <option value=""></option>
                                            <?php $c1 = mysqli_query($con, "SELECT * FROM customers WHERE status='Active'") or die (mysqli_error($con));
                                            while($c2 = mysqli_fetch_array($c1))
                                            {

Good afternoon,   I was wondering if you could help me out with a few things.  I have created a registration page and it stores the information into my database.  A success page then appears with some of the details they entered as a confirmation page.  Unfortunately I cannot get the information to appear on the page.  I have included some code, any help would be greatly appreciated.   <?php

on my index page, I have a form with the action of formData.php which is this code

Code: [Select]

<?php include("includes/connection.php"); 
//opens the database connection
//connection.php
//function connect() {
//global $mysql;
//$mysql = new MySQLi('localhost','user','password','billPay') or die('couldn not connect'. mysql_error());
//}

connect();
if(isset($_POST['submit'])){
$firstName = $_POST['firstName'];
$lastName = $_POST['lastName'];
$companyName = $_POST['companyName'];
$homePhone = $_POST['homePhone'];
$cellPhone = $_POST['cellPhone'];
$companyPhone = $_POST['companyPhone'];
}

$insert = $mysql->query("INSERT INTO names('firstName','lastName','companyName'), phone('home','cell','company') values('$firstName','$lastName','$companyName','$homePhone','$cellPhone','$companyPhone'");
if($insert){
echo "success!";
}
else
{
mysql_error();
}

?>


when I push the insert button, it goes to the formData.php page like it should be instead of giving an error or a success message, it's blank.

Hello, I have coded a contact form in PHP and I want to know, if according to you, it is secure! I am new in PHP, so I want some feedback from you.

Moreover, I have also two problems based on the contact form. It is a bit complicated to explain, thus, I will break each of my problem one by one.

FIRST:The first thing I want to know, is if my contact form secure according to you:

The HTML with the PHP codes:

Code: [Select]
<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {

//Assigning variables to elements
$first = htmlentities($_POST['first']);
$last = htmlentities($_POST['last']);
$sub = htmlentities($_POST['subject']);
$email = htmlentities($_POST['email']);
$web = htmlentities($_POST['website']);
$heard = htmlentities($_POST['heard']);
$comment = htmlentities($_POST['message']);
$cap = htmlentities($_POST['captcha']);

//Declaring the email address with body content
$to = 'alithebestofall2010@gmail.com';
$body ="First name: '$first' \n\n Last name: '$last' \n\n Subject: '$sub' \n\n Email: '$email' \n\n Website: '$web' \n\n Heard from us: '$heard' \n\n Comments: '$comment'";

//Validate the forms
if (empty($first) || empty($last) || empty($sub) || empty($email) || empty($comment) || empty($cap)) {
echo '<p class="error">Required fields must be filled!</p>';
header ('refresh= 3; url= index.php');
return false;

} 
elseif (filter_var($first, FILTER_VALIDATE_INT) || filter_var($last, FILTER_VALIDATE_INT)) {
echo '<p class="error">You cannot enter a number as either the first or last name!</p>';
return false;
} 
elseif (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
echo '<p class="error">Incorrect email address!</p>';
return false;
}
elseif (!($cap === '12')){
echo '<p class="error">Invalid captcha, try again!</p>';
return false;
}
else {
mail ($to, $sub, $body);
echo '<p class="success">Thank you for contacting us!</p>';
}
}
?>
<form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post">
<p>Your first name: <span class="required">*</span></p>
<p><input type="text" name="first" size="40" placeholder="Ex: Paul"/></p>

<p>Your last name: <span class="required">*</span></p>
<p><input type="text" name="last" size="40" placeholder="Ex: Smith"/></p>

<p>Subject: <span class="required">*</span></p>
<p><input type="text" name="subject" size="40" placeholder="Ex: Contact"/></p>

<p>Your email address: <span class="required">*</span></p>
<p><input type="text" name="email" size="40" placeholder="Ex: example@xxx.com"/></p>

<p>Website:</p>
<p><input type="text" name="website" size="40" placeholder="Ex: http//:google.com"/></p>

<p>Where you have heard us?: <span class="required">*</span></p>
<p><select name="heard">
<option>Internet</option>
<option>Newspapers</option>
<option>Friends or relatives</option>
<option>Others</option>
</select></p>

<p>Your message: <span class="required">*</span></p>
<p><textarea cols="75" rows="20" name="message"></textarea></p>

<p>Are you human? Sum this please: 5 + 7 = ?: <span class="required">*</span></p></p>
<p><input type="text" name="captcha" size="10"/></p>

<p><input type="submit" name="submit" value="Send" class="button"/>
<input type="reset" value="Reset" class="button"/></p>
</form>

SECOND PROBLEM:If a user has made a mistake, he gets the error message so that he can correct! However, when a mistake in the form occurs, all the data the user has entered are disappeared! I want the data to keep appearing so that the user does not start over again to fill the form.

THIRD: When the erro message is displayed to notify the user that he made a mistake when submitting the form, the message is displaying on the top of the page. I want it to appear below each respective field. How to do that? In JQuery it is simple, but in PHP, I am confusing!

how do I make it so that $message displays on form submit on the same page?:
Code: [Select]
