I am trying to create a nav bar where if you are a guest it displays a lock icon and 'Log in' and when you are logged in it displays a lock icon and 'Logout'.
Here is the code for my header:
<section class="top-bar-section">
<ul class="left">
<li><img src="images/icons/home_icon.png"> Home</li>
<li><img src="images/icons/about_icon.png"> About</li>
<li><img src="images/icons/pages_icon.png"> Showcase</li>
<li><img src="images/icons/videos_icon.png"> Videos</li>
</ul>
<ul class="right">
<?php
if (!empty($UserName))
{
echo <li><img src="../images/icons/login_icon.png"> Log in</li>;
}
else
{
echo <li><img src="../images/icons/login_icon.png"> Logout</li>;
}
?>
</ul>
</section>
the section I am working on is under <ul class="right">
and the error I am getting when testing the webpage is
`Parse error: syntax error, unexpected '<' in
C:\wamp\www...\header.php on line 16
PS: Line 16 is where the first 'echo' is
HELP! Please :) Thanks

Answer 1

You need to put the string in the echo statement in quotes (I'd suggest single-quotes, since you've got doubles in the text).

Answer 2

try like this you are missing quote on echo
if (!empty($UserName)) {
echo '<li><img src="../images/icons/login_icon.png"> Log in</li>';
}
else {
echo '<li><img src="../images/icons/login_icon.png"> Logout</li>';
}

Answer 3

The echo requires string like this
echo "Hello World";
So your echo statements must be like this:
echo '<li><img src="../images/icons/login_icon.png"> Log in</li>';
echo '<li><img src="../images/icons/login_icon.png"> Logout</li>';
If you want to use double quotes you should escape quotes that are in the string
echo "\""; /* would echo " */
