"name1" <[email protected]>, "name2" <[email protected]>
and once I will echo using php it will only echo the name and will skip the email address.

Always (always, always, I'm not kidding) use htmlspecialchars():
总是（总是，总是，我不是在开玩笑）使用htmlspecialchars()：
echo htmlspecialchars($_POST['contact_list']);
回答by Petah
Make sure your escaping the HTML characters
确保您转义 HTML 字符
E.g.
例如
// Always check an input variable is set before you use it
if (isset($_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.
这是因为尖括号和浏览器认为它们是标签。

Use htmlspecialchars():
echo htmlspecialchars($_POST['contact_list']);
You can even improve your form processing by stripping all tags with strip_tags()and remove all white spaces with trim():
您甚至可以通过使用以下命令剥离所有标签strip_tags()并删除所有空格来改进表单处理trim()：
function processText($text) {
$text = strip_tags($text);
$text = trim($text);
$text = htmlspecialchars($text);
return $text;
}
echo processText($_POST['contact_list']);

回答by Vusal
it is very simply. Just write your php value code between textarea tag.
这很简单。只需在 textarea 标记之间编写您的 php 值代码。
<textarea id="contact_list"> <?php echo isset($_POST['contact_list']) ? $_POST['contact_list'] : '' ; ?> </textarea>

Remove some of your textarea class like
删除一些你的 textarea 类，如
<textarea name="Address" rows="3" class="input-text full-width" placeholder="Your Address" ></textarea>
To
到
<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-textjust finds only $('input[type=text]'), that's why.
这取决于您的模板（采购模板）。开发人员已经包含了一些 JavaScript 来从 UI 上的正确对象中获取值，但是像这样的类input-text只是 finds only $('input[type=text]')，这就是原因。

Try this:
尝试这个：
<?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>
