Getting datetime from mysql into php? - javascript

I have the following code (a countdown timer using php and javascript) that I am working on. What I am trying to do is to get the datetime ($end_date) from the mysql and place it in the $date ='' inside my code.
This code will work just fine if i enter the date and time manually in the code like this: $date = 'September 17 2013 12:00:00 PM GMT';
but i need it to work some how like this:
$date = echo $dynamicList;
or like this maybe:
$date = echo $end_date;
I'm not sure what I am doing wrong!
here is my full code:
<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
?>
<?php date_default_timezone_set('GMT'); ?>
<?php
session_start();
// Run a select query to get my letest 6 items
// Connect to the MySQL database
include "config/connect.php";
$dynamicList = "";
$sql = "SELECT * FROM item ORDER BY id";
$query = mysqli_query($db_conx, $sql);
$productCount = mysqli_num_rows($query); // count the output amount
if ($productCount > 0) {
while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){
$id = $row["id"];
$product_name = $row["product_name"];
$date_added = strftime("Y-m-d", strtotime($row["date_added"]));
$end_date = strftime("Y-m-d H:i:s", strtotime($row["end_date"]));
$price = $row["price"];
$dynamicList .= '<div>' . $end_date . '
</div>';
}
} else {
$dynamicList = "No Records";
}
?>
<?php
$date = echo $dynamicList;
$exp_date = strtotime($date);
$now = time();
if ($now < $exp_date) {
?>
<script>
// Count down milliseconds = server_end - server_now = client_end - client_now
var server_end = <?php echo $exp_date; ?> * 1000;
var server_now = <?php echo time(); ?> * 1000;
var client_now = new Date().getTime();
var end = server_end - server_now + client_now; // this is the real end time
var _second = 1000;
var _minute = _second * 60;
var _hour = _minute * 60;
var _day = _hour *24
var timer;
function showRemaining()
{
var now = new Date();
var distance = end - now;
if (distance < 0 ) {
clearInterval( timer );
document.getElementById('countdown').innerHTML = 'EXPIRED!';
return;
}
var days = Math.floor(distance / _day);
var hours = Math.floor( (distance % _day ) / _hour );
var minutes = Math.floor( (distance % _hour) / _minute );
var seconds = Math.floor( (distance % _minute) / _second );
var countdown = document.getElementById('countdown');
countdown.innerHTML = '';
if (days) {
countdown.innerHTML += 'Days: ' + days + '<br />';
}
countdown.innerHTML += 'Hours: ' + hours+ '<br />';
countdown.innerHTML += 'Minutes: ' + minutes+ '<br />';
countdown.innerHTML += 'Seconds: ' + seconds+ '<br />';
}
timer = setInterval(showRemaining, 1000);
</script>
<?php
} else {
echo "Times Up";
}
?>
<div id="countdown"></div>
could someone please help me out with this?
I do not get any errors on my page. only a blank page and if I change $date = echo $dynamicList; to $date = '$dynamicList'; i get the Times Up message!
any help would be appreciated.

Change these lines:
$date = echo $dynamicList;
With the following code:
$date = "'".$end_date."'";
And define the $end_date as a global variable.
And also add the some more parameter in the following for timezone:
$end_date = strftime("Y-m-d H:i:s A T", strtotime($row["end_date"]));
^^^ add these
You are getting the timesup message because of your if condition is not correct:
if ($now < $exp_date) {
As you are comparing the unixtimestap with the timeformat.
Use this code:
$date = "'".$end_date."'";
$exp_date = strtotime($date);
$now = strtotime(date("Y-m-d H:i:s A T"));
Then compare these time. You need to change the $now also.

Woocommerce auction live countdown archive

I want to have a live countdown timer on my archive page/sliders where I count down the auction.
Currently using only PHP but this is not live ofcourse because I need to refresh the page. So I guess the best way would be javascript.
I currently have this code in my functions.php the years/months/days/ours work fine but seconds don't
`
function auction_end_date_countdown() {
global $product;
$product = apply_filters( 'yith_wcact_get_auction_product', $product );
ob_start();
if ( 'auction' === $product->get_type() ) {
$dateclose = $product->get_end_date();
if ( $dateclose ) {
$today = date("Y-m-d H:i:s");
$format_date = get_option( 'yith_wcact_general_date_format', 'Y-m-d H:i:s' );
$format = $format_date . ' ' . $format_time;
$date = ( date( 'Y-m-d H:i:s', $dateclose ) );
$diff = abs(strtotime($today) - strtotime($date));
$years = floor($diff / (365*60*60*24));
$months = floor(($diff - $years * 365*60*60*24) / (30*60*60*24));
$days = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24)/ (60*60*24));
$hours = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24 - $days*60*60*24)/ (60*60));
$minuts = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24 - $days*60*60*24 - $hours*60*60)/ 60);
$seconds = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24 - $days*60*60*24 - $hours*60*60 - $minuts*60));
if ($today < $date) {
printf("%d dagen, %d uren", $days, $hours);
echo $date;
// printf("%d maanden, %d dagen, %d uren", $months, $days, $hours);
}else{
echo 'Afgelopen';
}
}
}
$html = ob_get_clean();
return $html;
}
add_shortcode( 'veiling_eind_datum_aftellen', 'auction_end_date_countdown' );
`
I added the shortcode to my grid so each auction gets the ending time.
But now I am struggeling to implement a live times in to this.

Coundown Timer Inside ForEach Loop Php

I am trying to Show a Countdown Timer Inside Foreach loop for every record in PHP Codeigniter Framework, It is basically showing Datediff between current date and mysql database date value as how many days left, Below is my code.Problem is it is showing countdown timer for single record only not for every record i need
<?php foreach ($my_courses as $my_course):
$course_details = $this->crud_model->get_course_by_id($my_course['course_id'])->row_array();
<!-- countdown timer-->

$t=$course_details['live_class_schedule_time'];
//time difference in seconds for coundown timer
$date = new DateTime();
$date2 = new DateTime(date("yy-m-d h:i:s a", $t));
$diff = $date->getTimestamp() - $date2->getTimestamp() ;
echo $diff;
?></span>
<span id="<?echo $my_course['course_id']?>" class="timer" style="font-size:smaller;color:crimson;"></span>
<?php endif; ?>

What is the wrong I am doing and How to show the timer for every record

Your function name and call should also be unique.
EDIT
Also you messed up a log of code. I have commented the foreach loop and put my own for loop. Modify accordingly
Try this.
<?php
$my_course['course_id'] = 0;
for($i = 0; $i <= 2; $i++):
// foreach ($my_courses as $my_course):
// $course_details = $this->crud_model->get_course_by_id($my_course['course_id'])->row_array();
// You need to comment this out when you put your code live
$course_details['is_onlineclass'] = "Yes";
$course_details['live_class_schedule_time'] = time() + rand(0, 300);
$my_course['course_id'] += 1;
// remove till here
if ($course_details['is_onlineclass']==='Yes'):
?>
<span style="display:inline-block;font-size:12px;font-color:crimson;">
<?php
$t=$course_details['live_class_schedule_time'];
//time difference in seconds for coundown timer
$date = new DateTime();
$date2 = new DateTime(date("yy-m-d h:i:s a", $t));
$diff = $date->getTimestamp() - $date2->getTimestamp() ;
?>
</span>
<span id="<?php echo $my_course['course_id']; ?>" class="timer" style="font-size:smaller;color:crimson;"></span>
<?php endif; ?>
<script>
var initialTime = <?php echo $diff; ?>
var seconds = initialTime;
function timer<?php echo $my_course['course_id'];?>() {
var days = Math.floor(seconds/24/60/60);
var hoursLeft = Math.floor((seconds) - (days*86400));
var hours = Math.floor(hoursLeft/3600);
var minutesLeft = Math.floor((hoursLeft) - (hours*3600));
var minutes = Math.floor(minutesLeft/60);
var remainingSeconds = seconds % 60;
if (remainingSeconds < 10) {
remainingSeconds = "0" + remainingSeconds;
}
document.getElementById('<?php echo $my_course['course_id']?>').innerHTML = days + "days " + hours + "hours " + minutes + "min " + remainingSeconds+ "sec left";
if (seconds == 0) {
learInterval(countdownTimer);
document.getElementById('<?php echo $my_course['course_id']?>').innerHTML = "Completed";
} else {
seconds--;
}
}
var countdownTimer = setInterval('timer<?php echo $my_course["course_id"];?>()', 1000);
</script>
<?php endfor; ?>

Multiple Countdown using PHP and Javascript

I am currently stuck on a problem and not sure how to solve it. I am new to php and javascript coding so do please correct me if there is an easier way to do this.
My problem is that I am trying to get a countdown timer working for multiple data in mysql database. I have already made a successful countdown time function that only works with one data using the if statement in php, but when I try to do it with multiple data using the while statement in php it doesn't work.here is my php code
//TODAY'S DATE
$today = time();
//FETCHES DATE AND TIME FOR THE EVENT FROM DATABASE
$sql = "SELECT * FROM post";
$result = mysqli_query($conn, $sql);
while ($row = mysqli_fetch_assoc($result)) {
$title = $row['title'];
$cname = $row['cname'];
$team = $row['team'];
$description = $row['description'];
$endtime = $row['endtime'];
echo "<tr>";
echo "<td width='16%'><strong>Title:</strong></td>";
echo "<td width='16%'>$title</td>";
echo "</tr><tr>";
echo "<td width='16%'><strong>Client name:</strong></td>";
echo "<td width='16%'>$cname</td>";
echo "</tr><tr>";
echo "<td width='16%'><strong>Team:</strong></td>";
echo "<td width='16%'>$team</td>";
echo "</tr><tr>";
echo "<td width='16%'><strong>Description:</strong></td>";
echo "<td width='16%'>$description</td>";
echo "</tr><tr>";
echo "<td width='16%'><strong>End time:</strong></td>";
echo "<td width='16%'>$endtime</td>";
echo "</tr><tr>";
echo"</BR>";
echo"</BR>";
}
$conn->close();
below is my javascript that suppose to run the count down
<script language="JavaScript">
var today = new Date();
var DD = today.getDate();
var MM = today.getMonth()+1; //January is 0!
var YYYY = today.getFullYear();
//let get the Difference in Sec btw the two dates
var _DateFromDBProgEndDate = '<?php echo $endtime; ?>';
var ProgEndTime = new Date(_DateFromDBProgEndDate);
var TodayTime = new Date();
var differenceTravel = ProgEndTime.getTime()- TodayTime.getTime() ;
var seconds = Math.floor((differenceTravel) / (1000));
////////////////////////////////
var SecDiffFromToday = seconds;
var seconds = SecDiffFromToday;
function pad(n) {
// utility function to pad a number to 2 digits:
return ('0' + n).substr(-2);
}
function timer() {
var todaySeconds = Math.floor(new Date().getTime() / 1000);
// collect the html first in an array
var html = [];
// keep track whether there are still counters not yet zero:
var allDone = true;
// go through the list of dates:
endDatesInSeconds.forEach(function (endDateSeconds) {
var totalSeconds = endDateSeconds - todaySeconds;
var days = Math.floor(totalSeconds/24/60/60);
var seconds = Math.floor(totalSeconds - days*86400);
var hours = Math.floor(seconds/3600);
seconds = Math.floor(seconds - hours*3600);
var minutes = Math.floor(seconds/60);
seconds = seconds % 60;
// add a part of html
html.push(
totalSeconds <= 0
? 'project time Completed'
: days + ":" + pad(hours) + ":" + pad(minutes) + ":" + pad(seconds));
// when at least one counter is not complete, we are not done:
allDone = allDone && totalSeconds <= 0;
});
// now put the html in the document:
document.getElementById('countdown').innerHTML = html.join('<br/>');
if (allDone) {
clearInterval(countdownTimer);
}
}
var countdownTimer = setInterval('timer()', 1000);
</script>
the javascript run the countdown by getting it value from the php (var _DateFromDBProgEndDate = '<?php echo $endtime; ?>';)

FullCalendar doesn't display the proper time

I have looked at all the examples and I can't figure out why FullCalendar won't show the proper time for my events. For each event it just lists 12a instead of the actual time. Can someone please take a look at my code below and let me know what I am doing wrong.

Thanks!

That's the default time format for FullCalendar. You'll want to look at the timeFormat documentation for details on how to implement a change to it, and the formatDate documentation for specifics on how the time formats work.
As both an example and a quick fix to your specific problem, if you were to specify...
timeFormat: 'h:mmtt'
...in your calendar object, at the same level where you specify your event sources and theme, that should display the full "am" or "pm". Under this formatting, 7pm would display "7:00pm".

Javascript countdown only when page reload

i have opencart module daily deal, but the countdown timer is not working.
function code:
<?php
class ModelCatalogSpecialPriceCountDown extends Model {
public function getProductSpecialDates($product_id) {
(string) $display_output = null;
(string) $minute = 60;
(string) $hour = 60 * $minute;
(string) $day = 24 * $hour;
if ($this->customer->isLogged()) {
$customer_group_id = $this->customer->getCustomerGroupId();
} else {
$customer_group_id = $this->config->get('config_customer_group_id');
}
$query = $this->db->query("SELECT date_start, date_end FROM " . DB_PREFIX . "product_special WHERE product_id = '" . (int)$product_id . "' AND customer_group_id = '" . (int)$customer_group_id . "' AND ((date_start = '0000-00-00' OR date_start < NOW()) AND (date_end = '0000-00-00' OR date_end > NOW())) ORDER BY priority ASC, price ASC LIMIT 1");
if ($query->num_rows) {
$time_left = strtotime($query->row["date_end"]) - strtotime(date('Y-m-d'));
$days_left = floor($time_left/$day);
if ($time_left > 0)
{
$display_output = getdate();
$display_output["days_left"] = $days_left;
}
}
return $display_output;
}
}
?>
and the code using it:
<!-- Countdown start -->
<div id="defaultCountdown<?php echo $product['product_id'];?>" class="countdown_dashboard"></div>
<script type="text/javascript"><!--
$(document).ready(function() {
$('#defaultCountdown<?php echo $product["product_id"]; ?>').countdown({
until: new Date(<?php echo $product['yleft'];?>, <?php echo $product['mleft'];?> - 1, <?php echo $product['dleft'];?>)
});
});
//-->
</script>
My countdown doesn't work, the numbers change only when I refresh the page.
