Introduction & Demo

Today, I’m going to share “How to code calendar in PHP” videos.

Before you watch the video, please check the demo from here.

Coding calendar contains a lot of coding basics and functions like loops, mktime function, GET etc…
I think it will be helpful to learn how PHP works with HTML and how to deal with time functions.

Also, I used Bootstrap and Google Fonts in this tutorial.
Bootstrap helps us to make beautiful layout easily, and you can design your site without special CSS knowledge.

Once you’ve done, you can print it out and use as your schedule memo!

Happy Coding 🙂

      Please change $today like this.

    • Sara

      Hi ammar,
      You can insert your schedules by connecting with MySQL database. I’m working on new calendar tutorial series which you can add, edit, and delete schedules. Although it’ll not be a free version, try it if you’re interested 😉
      Thank you for watching my videos!

    Hi, do I need wamp for it to work?

    • Sara

      Hi CYN,
      Yes, you need a local or web server to run PHP file. Please install WAMP or XAMPP or MAPP… whichever you like.

    How to change the Script, if monday the first day in the week?

    • Sara

      Hi Daniel, try changing these 4 lines.

      // $str = date(‘w’, mktime(0, 0, 0, date(‘m’, $timestamp), 1, date(‘Y’, $timestamp)));
      $str = date(‘N’, mktime(0, 0, 0, date(‘m’, $timestamp), 1, date(‘Y’, $timestamp)));
      *N returns 1:Mon 2:Tue … 7:Sun

      // $week .= str_repeat(”, $str);
      $week .= str_repeat(”, $str – 1);

      // if ($str % 7 == 6 || $day == $day_count) {
      if ($str % 7 == 0 || $day == $day_count) {

      // $week .= str_repeat(”, 6 – ($str % 7));
      $week .= str_repeat(”, 7 – ($str % 7));

      Hope this helps 🙂

    I can’t get the Today portion to work. Am I missing something? Thank You in advance.

    date_default_timezone_set(“America/New_York”);

    if (isset($_GET[‘ym’])) {
    $ym = $_GET[‘ym’];
    } else {
    $ym = date(‘Y-m’);
    }

    $timestamp = strtotime($ym,”-01″);
    if ($timestamp === false) {
    $timestamp = time();
    }

    $today = date(‘Y-m-d’, time());

    $html_title = date(‘F | Y’, $timestamp);

    $prev = date(‘Y-m’, mktime(0, 0, 0, date(‘m’, $timestamp)-1, 1, date(‘Y’, $timestamp)));
    $next = date(‘Y-m’, mktime(0, 0, 0, date(‘m’, $timestamp)+1, 1, date(‘Y’, $timestamp)));

    $day_count = date(‘t’, $timestamp);

    $str = date(‘w’, mktime(0, 0, 0, date(‘m’, $timestamp), 1, date(‘Y’, $timestamp)));

    $weeks = array();
    $week = ”;

    $week .= str_repeat(”, $str);

    for ( $day = 1; $day <= $day_count; $day++, $str++) {
    $date = $ym.'-'.$day;
    if ($today == $date) {
    $week .= '’.$day;
    } else {
    $week .= ”.$day;
    }
    $week .= ”;

    if ($str % 7 == 6 || $day == $day_count) {
    if($day == $day_count) {
    $week .= str_repeat(”, 6 – ($str % 7));
    }
    $weeks[] = ”.$week.”;
    $week = ”;
    }
    }

      Hi Yohan, thank you for watching 🙂
      　
      Please change
      $today = date(‘Y-m-d’, time());
      to
      $today = date(‘Y-m-j’, time());
      　
      Sorry, it’s my mistake. Hope this works.

      • Yohan 8077

        Perfect. Thank You Very Much.

  • Yohan 8077

    Let me be more clear, it won’t write the td class=”today”

  • [d!p]

    Hi Sara,

    Thanks for this code! It’s excellent; How was wondering, how to get the selected values visible.
    For example, I add on the $day value, with and a POST_ and then when you click on it, you get show the selected “day” for example 15. Thanks in advance

    • Sara

      Hi [d!p], thank you for your comment 🙂
      　
      [you get show the selected “day” for example 15] means
      you want to change the color of the selected day, like ??
      　
      If so, change this line
      $today = date(‘Y-m-j’, time());
      to
      if (!empty($_POST[‘selected_date’])) {
      　$today = date(‘Y-m-j’, strtotime($_POST[‘selected_date’]));
      } else {
      　$today = date(‘Y-m-j’, time());
      }

      * I assume that the format of $_POST[‘selected_date’] is Y-m-j, like 2018-06-7.
      Hope this helps.

      You can’t run PHP scripts in HTML file.
      Please change a file name “calendar.php” then place it in the folder of your localhost. Hope this helps 🙂
