if ( $act == "htmlsubmit" ) {
$save ='Profile updated successfully';
$query4 = "UPDATE members SET htmlprofile = '$htmlprofile' WHERE username = '$myuser'";

Answer 1

There is no value attribute in textarea you have to enter the content between the <textarea>text</textarea>
See for reference tag_textarea
It should be like this
<textarea id="htmlprofile" name="htmlprofile" cols="33" rows="16" >
<?php echo $qry2[htmlprofile]; ?>
</textarea>
Refer to this answer also which-value-will-be-sent-by-textarea-and-why

Answer 2

Your div contentheadertext is not contained within the <form></form> so if you have inputs there, they won't be included in the form submission.
To resolve, move the opening <form> tag higher, so that it encloses all inputs.

Answer 3

the submit works fine. But you have no variables with the post data definied. And textareas haven't "value". And when you don't need fixed strings in your echo, don't use the "
try the following:
<textarea id="htmlprofile" name="htmlprofile" cols="33" rows="16"><?php echo htmlspecialchars($_POST['htmlprofile']); ?></textarea>

Answer 4

if you are trying to use a php variable inside HTML do that simply by echo $myvariable ; Quotes not required there. But if u are trying to echo a string use quotes just like echo 'mystring' .
Moreover when you are trying to pass some values as part of form submission, the required values should be between the tags
if you want to show any value inside text area, remember it doesn't have a 'value' attribute. So write the code like this: value to be displayed
