Inserting today date from form to database - php

Question

I'm trying to insert date when form is processed but in MySQL is inserting like
0000-00-00
I don't want user to insert date.
Here is my form
<form action="upload.php" method="post" enctype="multipart/form-data">
<textarea type="text" name="text" cols="40" rows="10"></textarea><br />
<input type="hidden" name="dt"/>
<input type="submit" name="upload" id="upload" value="Изпрати" />
And this is upload.php
<?php
if (isset($_POST['upload'])) {
$text = $_POST['text'];
$dt = date('Y-m-d', strtotime($_POST['Date']));
$db = new mysqli("localhost", "*****", "", "****");
if (mysqli_connect_error()) {
printf("Connect failed: ", mysqli_connect_error());
}
mysqli_set_charset($db, "UTF8");
$query = "INSERT INTO table (text, date) VALUES (?, ?)";
$conn = $db->prepare($query);
if ($conn == TRUE) {
$conn->bind_param("si",$text, $dt );
if (!$conn->execute()) {
echo 'error insert';
} else {
header("Location: ../admin/index.php");
exit;
}
} else {
die("Error preparing Statement");
}
} else {
echo 'error';
}
?>
What can be the problem?
edit:
In mysql the row for date is type - 'date'
edit2:
I forget about NOW()... is working perfect and is so simple.

Answer 1

I don't want user to insert date.
Then don't make it a part of the user-submitted form. As it stands, even if it's a hidden element, users can modify it to insert whatever date value they want. You don't want the user to insert the date, but your current code requires that the user insert the date.
If you just want it to be a system-known date, you can do this entirely in the INSERT statement at the database level:
INSERT INTO table (text, date) VALUES (?, NOW())
That way the database itself generates the current date, instead of relying on whatever the user submits. At this point you can completely remove the date input from the form and remove the parameter from the PHP code that builds the database query.

Answer 2

if you don't want user to be insert date than handle it at server side. My answer is for handle using PHP otherwise you can also go with NOW() mysql side handling.Choice up to you :
$dt = date('Y-m-d: H:i:s');
OR you can store it in databse as timestamp:
$dt=date("Y-m-d H:i:s");
$dt= strtotime($dt);
and retrieve it at front
date("Y-m-d H:i:s",$dt)

Answer 3

Replace in your code:
$query = "INSERT INTO table (text, date) VALUES (?, NOW())";
