Displaying input error messages next to the input field - php

I would like to display error checking next to the input field. Currently, errors are displayed at the top of the page.
Maybe there is some way to check for input errors?
I could not find a similar example where html and php code are separated into different files
Or my code is completely wrong.
index.php
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" type="text/css" href="css/style.css">
<title>testpage</title>
</head>
<body>
<?php
require('process.php');
?>

You can add the 'required' attribute to <input> elements, which get validated on form submission. E.g. <input type="date" name="date" required/> eliminating the necessity to write code for error output.
EDIT: here you can see how the warning is shown
Also, the validation
elseif ( $u_starttime > $u_endtime ){
echo "*Incorrect time";
}
is not required, since the user's choices already force starttime < endtime.
Cheers


Here is an example for setting date validation next to your date input fields.
in process.php:
` $errordate="";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$u_date = filter_var($_POST["date"]);
if (empty($u_date)){
$errordate= 'Date is empty!';
}}
and in your index.php:
<input type="date" name="date"/> * <?php echo "<p style='color:red;'>".$errordate . "</p>"; ?>

It gives first warning that mysql is deprecated so I used below syntax but still it gives error:
mysqli_real_escape_string(htmlspecialchars($link,$_POST['name']));
Second major error its giving is that it takes me to this error message and makes all form fields empty. The line its showing always is:
ERROR: Please fill in all required fields!
Please Guide!

$servername = "localhost:3306";
$username = "root";
$password = "<Password here>";
$dbname = "TUTORIALS";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO tutorials_inf(name)VALUES ('".$_POST["name"]."')";
if (mysqli_query($conn, $sql)) {
echo "New record created successfully";

PHP to MYSQL form validation and database insertion with PHP_SELF and php process

I'm trying to use a php form saved on the artistRegister.php below and process it with the file at the bottom named processArtist.php .
I can't find the proper way to populate the fields in case there's an error and when I submit it to the database, I get an empty record on the database.
I'm populating a dropdown list on the navigation bar at header.php and using the same code to connect to the database, so it's not a database communication problem, since I'm able to create new empty records on the submit button press.
Tried several ways to make it work but would appreciate any help debugging the problem at hand.
Thank you advance.

Updating post with PHP & MySQL

I'm building a sort of blog system, but I'm having trouble with editing an existing 'post' in the system. It is collecting the data from the database, and it displays it. But when I click the update button, I get this error. I've looked for it, checked my code couple of times, but I just couldn't find anything. This is the error.
SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens
And this is my code.

require_once('../../includes/config.php');
//if not logged in redirect to login page

:patient_id is missing from the $stmt->execute() function. Please add it and try again.

In your update query you forgot about :patient_id to bind
And yes, remove $ before column names.

But I was unable to add records through this form to the relevant table. I can not understand what I am going wrong. Can any one help me?... Pls...

Form's Attribute method's default value is get
You should specify it like this
<form id="contactform" method="post">
Now you can use $_POST to get data!

SESSION variable value is not passing

I'm trying to pass a value from a select input control on an HTML form.
When I hardcode it, it gets echoed, when not, all I get is this:
The invention type did not go through correctly.
Here is my page1.php:
<?php
session_start();
$_SESSION['invtype'] = $invtype;
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
if (isset($_POST['Submit'])) {
if ($_POST['firstname'] != "") {
$_POST['firstname'] = filter_var($_POST['firstname'], FILTER_SANITIZE_STRING);
if ($_POST['firstname'] == "") {
$errors .= 'Please enter a valid first name.<br/><br/>';
}
} else {
$errors .= 'Please enter your first name.<br/>';
}
if ($_POST['lastname'] != "") {
$_POST['lastname'] = filter_var($_POST['lastname'], FILTER_SANITIZE_STRING);
if ($_POST['lastname'] == "") {
$errors .= 'Please enter a valid last name.<br/><br/>';
}
} else {
$errors .= 'Please enter your last name.<br/>';
}
if (!$errors) {header("location: offerform_switch.php");
}
else {
echo '<div style="color: red">' . $errors . '<br/>
</div>';
}
}
?>

Here is my offerform_switch.php:
<?php
session_start();
// echo variable from the session, we set this on our other page
echo $_SESSION['invtype'];
$invtype = $_SESSION['invtype'];
//connect to your database ** EDIT REQUIRED HERE **
mysql_connect("mysql.myserver.com","myuser","mypassword"); //(host, username, password)
//specify database ** EDIT REQUIRED HERE **
mysql_select_db("invention") or die("Unable to select database"); //select which database we're using
switch ($invtype){
case "product":
include("page2_product.php");
break;
case "software":
include("page2_software.php");
break;
default:
echo "The invention type did not go through correctly.";
}
?>
What am I doing wrong?
Thank you!

It should be
$_SESSION['invtype'] = $_POST['invtype'];

You're missing "session_id();" right below the "session_start();". I don't know why exactly it's required, but if I remember correctly, it is.
