如何将会话变量传递到PHP中的表单？

Question

I currently have this code but it is not display the u_mail

if (isset($_SESSION['u_email'])) {
echo "<form method='POST' action='".setComments($connComment)."'>
<input type='hidden' name='uid' value='$_SESSION['u_email']'>
</form>" } 
getComments($conn)

How do I display it?

I tried testing it by doing:

<?php
 echo $_SESSION['u_email'];
 ?>

And it works completely fine. It is just when I put it in an echo. I actually SHOULD put it in echo. Is there a way in PHP to do that?

Thank you!

Just break out from the string and concatenate, like this:

echo "<form method='POST' action='".setComments($connComment)."'>
<input type='hidden' name='uid' value='" . $_SESSION['u_email'] ."'>
</form>";
