Not being able to verify password SQL

Not being able to verify password SQL - javascript

Update: After someone suggested in comments it's working now. I am still not able to work the login/logout button that's in index.php file. When I log in it does verify the password, but does not show the logout button. It shows the error in index.php (I have commented out the line) it says undefined index name Any help is appreicated.
I have a signup and login form in my website. I am able to signup properly and I am storing the password as hashed. When I try to login it keep saying wrong password. I am assuming there might be something wrong with my code since the password I am typing is correct.
index.php

How to retain Form data After Incomplete Form Submission

This is my code,
PHP
if(isset($_POST['submit'])){
if (empty($_POST["name"])) {
$NameErr = "Name is required";
} else {
$name = Test_User_Input($_POST["name"]);
$name = mysqli_real_escape_string($connection , $name);
}
if (empty($_POST["contact"])) {
$ContactErr = "Contact is required";
} else {
$contact = Test_User_Input($_POST["contact"]);
$contact = mysqli_real_escape_string($connection , $contact);
}
if (empty($_POST["email"])) {
$EmailErr = "Email is required";
} else {
$email = Test_User_Input($_POST["email"]);
$email = mysqli_real_escape_string($connection , $email);
}
if (empty($_POST["pan"])) {
$PanErr = "PAN is required";

$pan = Test_User_Input($_POST["pan"]);
$pan = mysqli_real_escape_string($connection , $pan);
}
if (empty($_POST["dob"])) {
$DobErr = "DOB is required";

if (!empty($name) && !empty($contact) && !empty($email) && !empty($pan) &&
!empty($dob) && !empty($gender){
$query = "INSERT INTO form ( name, contact, email, pan, birthday,
gender )VALUES ('$name' , '$contact' , '$email' , '$pan' , '$dob' ,

I want to Know, when the user fails to submit the form, how can I retain the form values, so user don't have to refill it.
Also if user forgets to fill one value , How to focus on that particular Field.?
ALSO
when the form is submitted and when I refresh The page, the form is again Refilled and data is sent again.
How can I prevent that?
One option is to redirect to another page after the submission, but again when the user will press back button, the form data is sent again.
Is there anything here which can be done?

For retain the filled values of the fields.
<input type="text" name="name" id="name" placeholder="Full Name" class="form-control-kyc" value="<?php echo if(isset($_POST['$name'])? $_POST['name'] : ''; ) ?>">
To avoid the auto resubmission of the data you can check whether the submit button pressed or not, if not the form data will not be added to Database and redirect it to index.php
<?php
if(isset($_POST['your-submit-button-name'])){
//within this curly brackets add your codes
}else{
header('Location: index.php');
die();
}
?>

If you want to keep the values stored you can simply echo the post value back as shown below.
<input type="text" name="name" id="name" placeholder="Full Name" class="form-control-kyc" value="<?php echo isset($_POST['name']) ? $_POST['name'] : '' ?>">

How to show selected image and its name?

I am studying and simply making an user registration form where there are several fields and the user has to upload its profile picture. I use php in order to validate the data before submitting.
After hitting the submit button it validates the data and refreshes the page due to which the filled data is gone. So we use ex. value="<?php echo $name; ?>" in the input value in order to preserve the data inserted by the user. It is possible with the simple input types such as text and others but how do we preserve the data of the image and show it in the image container and show the name of the selected image in the input type file.
<!DOCTYPE html>
<!-- form -->
<?php
$nameError = $genderError = $emailError = $mobileError = $imageError = "";
$name = $gender = $email = $mobile = $image = "";
$imagePath = $_FILES['image']['name'];
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if (empty($_POST["name"])) {
$nameError = "Please provide Name";
} else {
$name = validateInput($_POST["name"]);
}
if (empty($_POST["gender"])) {
$genderError = "Please select Gender";
} else {
$gender = validateInput($_POST["gender"]);

I am trying to create a dynamic website using php. The site is uploaded to a free domain this is my first real world project so I want to put in as best as I can. I created a modal, in it there is a form and I want this from to validate and without refreshing the page. but I don't know why my mail() is not working please can someone tell me what I am doing wrong.
This is my fixed form inside the modal:
<div class="modal fade" id="myModal" tabindex="-1" role="form" aria-labelledby="#modalLabel">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">

</button>

This is the php form validation in my includes folder:
<pre>
<?php
if (isset($_POST['submit'])) {
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$message = $_POST['message'];
$errorEmpty = false;
$errorEmail = false;
$errorPhone = false;
if (empty($name) || empty($email) || empty($phone) || empty($message)) {
echo "<span class='err'>Fill in all fields!</span>";
$errorEmpty = true;
}
elseif (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
echo "<span class='err'>Invalid email please make sure you enter a
valid email address!</span>";
$errorEmail = true;
}
elseif (!preg_match("/^(\d[\s-]?)?[\(\[\s-]{0,2}?\d{3}[\)\]\s-]{0,2}?
\d{3}[\s-]?\d{4}$/i",$phone)) {
echo "<span class='err'>Please enter only a valid phone number!
</span>";
$errorPhone = true;
}
else{
// add resipeants
$to = "danjumashiwaju#gmail.com";
// create subject
$subject = "$name sent you a message from www.djshumzy.com";
// construct a message
$msg = "Name: $name\r\n";
$msg .= "Email: $email\r\n";
$msg .= "Tell: $phone\r\n";
$msg .= "Message: \r\n$message";
$msg = wordwrap($meg, 70);
//set mail header
$headers = "MINE-Version: 1.0\r\n";
$headers .= "Content-type: text/plain; charset=1so-8859-1\r\n";
$headers .= "From: $name <$email>\r\n";
$headers .= "X-priority: 1\r\n";
$headers .= "X-MSMail-priority: High1\r\n\r\n";
mail( $to, $subject, $msg, $headers);
} if (mail === 1) {
echo "<span class='suc'>Thank You!...Your Message has been Sent !
</span>";
}
}
?>
<script>
$("#mail-name, #mail-email, #mail-phone,
#mail-message").removeClass("input-error");
var errorEmpty = "<?php echo $errorEmpty; ?>";
var errorEmail = "<?php echo $errorEmail; ?>";
var errorPhone = "<?php echo $errorPhone; ?>";
if (errorEmpty == true) {
$("#mail-name, #mail-email, #mail-phone,
#mail-message").addClass("input-error");
}
if (errorEmail == true) {
$("#mail-email").addClass("input-error");
}
if (errorPhone == true) {
$("#mail-phone").addClass("input-error");
}
if (errorEmpty == false && errorEmail == false && errorPhone == false) {
$("#mail-name, #mail-email, #mail-phone, #mail-message").val("");
}
</script>
</pre>
Here is my jquery validation(.js)
$(document).ready(function() {
$("form").submit(function(event) {
event.preventDefault();
var name = $("#mail-name").val();
var email = $("#mail-email").val();
var phone = $("#mail-phone").val();
var message = $("#mail-message").val();
var submit = $("#mail-submit").val();
$(".form-msg").load("includes/contact_process.php", {
name: name,
email: email,
phone: phone,
message: message,
submit: submit
});
});
});// END FORM VALIDATING
Please what do I have to do to make this from submit to emails and validate at the same time.
Thus the form validates but it does not send the email and just gives an error message instead.

Use https://jqueryvalidation.org/
$( "#myform" ).validate({
rules: {
field: {
required: true
},
email: {
required: true,
email: true
}
},
messages: {
field: "Please Enter Your Name",
email: "Please Enter Your Email Address"
}
});
<link href="https://jqueryvalidation.org/files/demo/site-demos.css" rel="stylesheet"/>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdn.jsdelivr.net/jquery.validation/1.16.0/jquery.validate.min.js"></script>
<form id="myform">
<label for="field">Enter Name : </label>
<input type="text" class="left" id="field" name="field">
<br/>
<label for="email">Email Address: </label>
<input type="text" id="email" name="email">
<br/>
<input type="submit" value="Validate!">
</form>
This jQuery plugin makes simple clientside form validation easy.
