Quite simple really. As you checked it exists and moved it into a variable you can just echo the $id into the value attribute of that input tag.
<input type="hidden" name="id" value="' . $id . '" />
Using your code:
echo '
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<form action="updatevideo.php" method="post" role="form">
Title: <input name="title" type="text" required> <br />
description:<input name="desc" type="text" required> <br />
url: <input name="ytl" type="text" required> <br />
<input type="hidden" name="id" value="' . $id . '" />
<input type="submit" name="addVideo" value="Add New Video" />
</form>
</body>
</html>';
Define the VALUE attribute :
<input type="hidden" name="id" value="ID_VALUE"/>
OR if you have id in varible than use below code :
<input type="hidden" name="id" value="<?php echo $id; ?>"/>
OR
As you are using the HTML in PHP than:
<input type="hidden" name="id" value="'.$id.'"/>
ID_Value should be your id like 1,2,3..etc.
And Get the id on Action page :
$id = $_POST['id'];
Apart from this you have mention POST in form method and on your
action page you are trying to get the values using GET method,
which is wrong.
Edited due to question edit.
<input type="hidden" name="id" value="'.$id.'" />
You echo a big block of text, this way you can concatenate the $id by stopping block output, including $id and resuming block output.

This code is intended to just take an ID and Pass without any kind of authentication and remember the data if the checkbox were to be checked. I can not figure it why is it not saving the data to cookies.
<?php
if(isset($_POST["chk"],$_POST["id"],$_POST["pass"])) {
$id=$_POST["id"];
$pwd=$_POST["pass"];
if (isset($_POST["chkbx"])){
setcookie("id","$id",time()+3600);
setcookie("pwd","$pwd",time()+3600);
$id=$_COOKIE["id"];
$pwd=$_COOKIE["pwd"];
}
print "Your ID " . $id;
print "Your PASS ". $pwd;
}
?>
<html>
<head>
<title>
Remember Me
</title>
</head>
<body>
Please Enter ID and PASS
<form method="post" >
Enter ID
<input type="text" name="id" />
Enter PASS
<input type="text" name="pass" />
<input type="submit" value="submit" /><br>
<input type="checkbox" name="chkbx" />Remember Me
<input type="hidden" name="chk" value="true" />
</form>
</body>
</html>
You code is correct but it needs to clean it up
in this part I add a condition to check is there is anything first in the $_COOKIE
before print it
if(isset($_COOKIE['id']) && isset($_COOKIE['pwd'])){
print "Your ID: " . $_COOKIE['id'] . '<br>';
print "Your PASS: ". $_COOKIE['pwd'] . '<br>';
}
your code will be like this
<?php
if($_SERVER['REQUEST_METHOD'] == 'POST') {
$id = $_POST["id"];
$pwd = $_POST["pass"];
if (isset($_POST["chkbx"])){
setcookie("id", $id ,time()+3600);
setcookie("pwd", $pwd, time()+3600);
}
}
if(isset($_COOKIE['id']) && isset($_COOKIE['pwd'])){
print "Your ID: " . $_COOKIE['id'] . '<br>';
print "Your PASS: ". $_COOKIE['pwd'] . '<br>';
}
?>
<html>
<head>
<title>
Remember Me
</title>
</head>
<body>
Please Enter ID and PASS
<form method="post" >
Enter ID
<input type="text" name="id" value="<?= isset($_COOKIE['id'])? $_COOKIE['id']: '' ?>" />
Enter PASS
<input type="text" name="pass" value="<?= isset($_COOKIE['pwd'])? $_COOKIE['pwd']: '' ?>" />
<input type="submit" value="submit" /><br>
<input type="checkbox" name="chkbx" />Remember Me
<input type="hidden" name="chk" value="true" />

I followed a online tutorial to connect my php code with MySQL. After I click the submit button, it said it cannot find the object (page). I did not see any code in my code? Any idea for me how to debug this code?
<?php
$user = 'root';
$pass = 'xxxxxx';
$db = 'testDB';
$db = new mysqli('localhost', $user, $pass, $db) or die("Unable to connect");
echo"Great work!";
$id ="";
$fname="";
$midname="";
$lname="";
function getPosts()
{
$posts =array();
$posts[0]=$_POST['Contact_ID'];
$posts[1]=$_POST['first_name'];
$posts[2]=$_POST['middle_name'];
$posts[3]=$_POST['last_name'];
return $posts;
}
//search
if(isset($_POST['search']))
{
$data = getPosts();
$search_Query="select * from Contact where contact_ID =$data[0]";
$search_Result=mysql_query($db, $search_Query);
if($search_Result)
{
if(mysql_num_rows($search_Result))
{
while($row=mysql_fetch_array($search_Result))
{
$id =$row['contact_ID'];
$fname =$row['first_name'];
$midname =$row['middle_name'];
$lname =$row['last_name_name'];
}
}
else
{
echo"No data for this Id";
}
}
else
echo"Result error";
}
?>

remove php_insert_update_delete_search.php from the action of your form. The form is being redirected to php_insert_update_delete_search.php page when you click search button
<form action="" method="post">
<input type="number" name="contact_ID" placeholder="Id" value="<?php echo $id;?>"><br><br>
<input type="text" name="first_name" placeholder="First Name" value="<?php echo $fname;?>"><br><br>

<input type="submit" name="insert" value="Add">
<input type="submit" name="update" value="Update">
<input type="submit" name="search" value="Find">

</form>
See You Have applied an action in your form tag . This action means that when ever a user will click on any button related to that form he or she will be redirected to that page (mentioned in action ) . So u need to make a page php_insert_update_delete_search.php and has to apply logic there for inserting the data .
If your wanting the form to go to another page to run code to process what you need
<form action="pageyouneed.php" method="post">
if you want to use the current page to parse your code:
<form action="<?php echo $_SERVER["PHP_SELF"];?>" method="post">
$_SERVER["PHP_SELF"]; // Will return current document to parse code.
I am working on a php situation that i have. What it should do is like. each product has a unique id value. if the product id is posted throught submit button, A count action should be activited to count the number of time that product id is posted, so increment.
I hope i exposed the situaation clearly. This is the way i thought doing it, but can't get it work:
<?php
if (isset($_POST['submit'])) {
$do = count($_POST['id']);
echo $do;
if ($do > 1)
{
$i= $do+1;
echo $i;
}
}
?>

If I assume the value in the hidden input #id is the times users vote the product:
if (isset($_POST['submit'])) {
$do = count($_POST['id']);
echo $do++;
}
If I assume it incorrectly I don't understand what you want to do, sincerly.
I would like to know how to increase a element, each time that element is posted.
I have to use for loop for the auto increment, but i am not getting right. So any advise or guidance will be great.
Here is the way i have tried to do:
Thanks
<?php
$id=0;
if (isset($_POST['submit'])) {
$do = $_POST['prodCode'];
$di = count($do);
while ($di > $id) {
$id++;
echo $id;
}

Try below code, counts are stored in session, but for real life app you should use database and also you should get your products from database:
<?php
// initialize counts for f102 and W122 products
if (!isset($_SESSION['count_f102']) {
$_SESSION['count_f102'] = 0;
}
if (!isset($_SESSION['count_W122']) {
$_SESSION['count_f102'] = 0;
}
if (isset($_POST['submit'])) {
$do = $_POST['prodCode'];
// increment count for product which was submitted
$_SESSION['count_'.$do] = 1+ (int) $_SESSION['count_'.$do];
}
?>

Are your $_POST['prodCode'] always in the form one letter + id ? If yes maybe this could help :
if (isset($_POST['prodCode'])) {
$value = $_POST['prodCode'];
// save the letter
$letter = substr($value, 0, 1);
// get id
$id = (int) substr($value, 1, strlen($value) - 1);
// get value with letter and incremented id
$valueIncremented = $letter . ++$id;
}
// with $_POST['prodCode'] = 'f102' you will get $valueIncremented = 'f103'
Hope it helps.
When I input numeric value in Number 1 and Number 2, and press "Add". It does not display the total added value. Please see my coding below. and advice me, what to is the problem, and what can be done.

You are echoing the result data into the <head>, so it will not be displayed.
You forgot to echo $add.
Your <input>s are of type button and not submit, so the form will not be submitted to the server.
Because you are echoing the previously entered values into the form, <input type="reset"> will probably not do what you want/expect it to do. I think it would be better to implement this as another submit.
Because this form affects only what the next page displays and does not make a permanent change to the server, you should use the GET method and not POST.
Try this:
<html>
<head>
<title>Simple Calculator</title>
<script type="text/javascript"></script>
</head>
<body>
<h1>Simple Calculator</h1>
<form action="simple_calculator.php" method="get">

The solution of DaveRandom works fine if you change this
action="simple_calculator.php"
by
action="<?php echo $_SERVER['PHP_SELF'] ?>"
