I also have other codes using the setTimeout

<p id="HHootteeLLClock"></p>

<script>
var serverClock = new Date(<?php echo time() * 1000 ?>);
timeInterval(); //start the time interval
function timeInterval(){  
var currentMS = serverClock.getTime();
   currentMS += 1000;
   serverClock.setTime(currentMS);
   document.getElementById('HHootteeLLClock').innerHTML = "The date today is " + serverClock.toDateString() + "<br>" + "The time today is " +  serverClock.toTimeString();
   setTimeout(timeInterval, 1000);  
}
</script>

Hello. I got some code or other technique/solution which I found while researching in the internet. Here is the code:

 <div id="websiteClock"></div>
<script>
    var serverClock = new Date(<?php echo time() * 1000 ?>);
    function startInterval(){  
        setInterval('updateTime();', 1000);  
    }
    startInterval();//start the time interval
    function updateTime(){
        var currentMS = serverClock.getTime();
        currentMS += 1000;
        serverClock.setTime(currentMS);
        document.getElementById('websiteClock').innerHTML = serverClock.toDateString() + " " 
         + serverClock.toTimeString();
    } 
</script>

RIght now I am still looking for another way of solution/technique. Please share codes on this topic. Thank you.

Hello. I already tried using JavaScript Clock With Timing Event Code like this:

<script>
function startTime() {
    var today = new Date();
    var h = today.getHours();
    var m = today.getMinutes();
    var s = today.getSeconds();
    m = checkTime(m);
    s = checkTime(s);
    document.getElementById('txt').innerHTML =
    h + ":" + m + ":" + s;
    var t = setTimeout(startTime, 500);
}
function checkTime(i) {
    if (i < 10) {i = "0" + i};  // add zero in front of numbers < 10
    return i;
}
</script>

But I notice it will be much better to use PHP Server Date/Time to avoid user's device incorrect time/clock.

Anyone here can help me to share code or other technique/solution on how to use PHP Server Date/Time to create clock with timing event to display in a website.

Hi Dodra. I visited the link you gave. The website has an application for calendar reservation system. I already seen many of this kind in Wordpress Plugin website available for free version. However what I need is a simple calendar with Start Date and End Date selection just like this url:

http://iammarvin261.x10host.com/wphottel1a/single-bed-2/

Hello. Right now I am looking for an open source code for hotel online reservation calendar with check-in(start date) - check-out(end date) selection.  It may be a PHP code, JavaScript, JQuery or any relate javascript library which do not need to use javascript server like node.js

Please visit the url for a example calendar selection:

http://iammarvin261.x10host.com/wphottel1a/single-bed-2/

I will use the source code to change/remodel my current check-in/checkout reservation form.

Can you help me easily find the source code on your CP Reservation Calendar on your php plugin files.

Thanks justsomeguy  A good information about using  PHP SUPERGLOBALS $_SERVER[‘HTTP_REFERER’]; and PHP Session code $_SESSION[“session_name”]; 

I will now use PHP Session code $_SESSION[“session_name”]; 

Hi to all. Sorry for late reply. It took me 4 days to choose how block unauthorized access to my WordPress php plugin file using JQUERY AJAX.

I tried to to use wordpress is_user_logged_in() function but you can only use this function if the php file is included on WordPress plugin main php file.

I decided to choose PHP SUPERGLOBALS $_SERVER[‘HTTP_REFERER’]; over PHP Session code $_SESSION[“session_name”];

I will add sample code:

/** javascript JQuery AJAX code of my php file which can copy/get through a browser by any user */

$(document).ready(function(){
        		$.post("/wp-content/plugins/SLMS/UserRecord.php", 
			{
			saveUserBtn: "Save", FName: fname, LName: lname, UNumber: unumber, address: address, contact: contact, email: email
   			},
			function(data, status){
 			document.getElementById('userr-page-notice').innerHTML = data;
				if(data.includes("New record saved.")) {
					document.getElementById("userRecord").reset();
				}
        		});
		});

/** Here is the code to my other php file that contains database access and saving data to database */
<?php
if($_SERVER['HTTP_REFERER'] == "https://iammarviin26.000webhostapp.com/user-record/") {
    if(isset($_POST['saveUserBtn']) and $_SERVER['REQUEST_METHOD'] == "POST") { 
        insertRecord();
	/**
	insertRecord();
	echo "working" ;
	*/
	
	}

	elseif(isset($_POST['searchUNBtn']) and $_SERVER['REQUEST_METHOD'] == "POST") {
	    searchUNRecord();
	
	/**
	searchUNRecord();
	echo $_POST['searchUN'];
	echo "Success";*/
	}

	elseif(isset($_POST['updateUserBtn']) and $_SERVER['REQUEST_METHOD'] == "POST") {
    	updateRecord();
	/**
	updateRecord();
	echo $_POST['ID'];
	echo "Update Status";*/
    }
}
/** Other php code/script that contains database credentials/sql script */

/** While using PHP SUPERGLOBALS $_SERVER['HTTP_REFERER']; any users cannot access my php file without the correct http referrer and actively login to my web application. */
?>

In case you cannot use wordpress is_user_logged_in() you can use SUPERGLOBALS $_SERVER[‘HTTP_REFERER’]; or PHP Session code $_SESSION[“session_name”];

Any suggestion or comment
Thanks

Hello. I made a WordPress plugin with a JQuery-AJAX/JSON code in a php file like this:

$(document).ready(function(){
$.post(“/wp-content/plugins/SLMS/UserRecord.php”,
{
saveUserBtn: “Save”, FName: fname, LName: lname, UNumber: unumber, address: address, contact: contact, email: email
},
function(data, status){
document.getElementById(‘userr-page-notice’).innerHTML = data;
if(data.includes(“New record saved.”)) {
document.getElementById(“userRecord”).reset();
}
});
});
/** end of code */

I also notice that any user can view my javascript code with their own browser. I also noticed that any user/unauthorized user can copy these JQuery-AJAX/JSON code and pass/save/modify data to MySQL database using the link to my php file. I will also write the code for my php file:

if(isset($_POST[‘saveUserBtn’]) and $_SERVER[‘REQUEST_METHOD’] == “POST”) {
insertRecord();
}
elseif(isset($_POST[‘searchUNBtn’]) and $_SERVER[‘REQUEST_METHOD’] == “POST”) {
searchUNRecord();
}
elseif(isset($_POST[‘updateUserBtn’]) and $_SERVER[‘REQUEST_METHOD’] == “POST”) {
updateRecord();
}
/** codes to access MYSQL Database */
/** end of code */

I notice that many developers also used these kind of JQuery-AJAX/JSON codes. I want to know what is the code to block unauthorized users to access/pass data to my php file when unauthorized users use JQuery/JSON code. I will also mention “web host cpanel File Permission” to see if this web server configuration can help.
