Keeping textarea data in php-CodePudding

i want to keep a textarea data in php, so when i refresh the page the text is still there. So I tried this, but everytime i refresh the page the text disappears. If someone can help me , i'd be thankful.

PHP code:

<?php 
$comments = "";
$comments= $_POST['comments'];
?>

HTML code:

<textarea name="comments" value="<?php echo $comments ?>" cols="30" rows="3"  placeholder="add some infos about yourself !!"></textarea><br>

CodePudding user response：

The textarea doesn't have a value attribute, so if you want to put a value in there you need to do it in middle of the tags:

<textarea name="comments" cols="30" rows="3"  placeholder="add some infos about yourself !!"><?php echo $comments ?></textarea>
