    Always (always, always, I'm not kidding) use htmlspecialchars():

    echo htmlspecialchars($_POST['contact_list']);

    Try this:

    <?php /* the php */ ?>
<?php 
    if ($_POST['submit']) {
        // must work
        echo $_POST['contact_list'];
    };
?>


 <?php /* and the html */ ?>

<!doctype html>
<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>teszt</title>
    </head>
    <body>
        <form method="post" action="<?php echo $_SERVER['PHP_SELF'] ?>">
            <textarea id="contact_list" name="contact_list"></textarea>
            <input type="submit" name="submit" value="Send" id="submit"/>
        </form>
    </body>
</html>

    Make sure your escaping the HTML characters

    E.g.

    // Always check an input variable is set before you use it
if (isset($_POST['contact_list'])) {
    // Escape any html characters
    echo htmlentities($_POST['contact_list']);
}

    This would occur because of the angle brackets and the browser thinking they are tags.

    See: http://php.net/manual/en/function.htmlentities.php

    //My Form
<form id="someform">
        <div class="input-group">
            <textarea placeholder="Post your Comment Here ..." name="post" class="form-control custom-control" rows="3" style="resize:none"></textarea> 
            <span class="input-group-addon">                                            
                <button type="submit" name="post_comment" class="btn btn-primary">
                    Post
                </button>
            </span>
        </div>
    </form>

//your text area get value to URL
<?php
        if(isset($_POST['post_comment']))
        {
            echo htmlspecialchars($_POST['post']);
        }

    ?>

//print the value using get
echo $_GET['post'];

//url must be like this
http://localhost/blog/home.php?post=asdasdsad&post_comment=

//post value has asdasdsad so it will print to your page

    Remove some of your textarea class like

    <textarea name="Address" rows="3" class="input-text full-width" placeholder="Your Address" ></textarea>

    To

    <textarea name="Address" rows="3" class="full-width" placeholder="Your Address" ></textarea>

    It's dependent on your template (Purchased Template). The developer has included some JavaScript to get the value from correct object on UI, but class like input-text just finds only $('input[type=text]'), that's why.

    it is very simply. Just write your php value code between textarea tag.

    <textarea id="contact_list"> <?php echo isset($_POST['contact_list']) ? $_POST['contact_list'] : '' ; ?> </textarea>
