Any variables contained inside single quotes won't be parsed, so...

 

<?php

$url=$_COOKIE["username"];

echo ("<a href=\"http://localhost/members/$url/$url.php\">My profile</a>");

?>

[sinista]

ok so i kinda get what you just said variables in single quotes wont get passed but why did you add a slash after href?

 

my code

 

echo ('<a href="http://localhost/members/$url/$url.php">My profile</a>');

 

your code

 

echo ("<a href=\"http://localhost/members/$url/$url.php\">My profile</a>");

 

?

Because you have to escape the " as PHP will think that the end of the echo is at the 2nd " , but it's not it's the fourth one,

 

look at the change in colours below to understand...

 

Correct:

<?php

$url=$_COOKIE["username"];

echo ("<a href=\"http://localhost/members/$url/$url.php\">My profile</a>");

?>

 

Incorrect:

<?php

$url=$_COOKIE["username"];

echo ("<a href="http://localhost/members/$url/$url.php">My profile</a>");

?>

 

so in the incorrect version, only <a href= will be echoed.

You could also do something along the lines of..

 

<?php

$url=$_COOKIE["username"];

echo ("<a href=\"http://localhost/members/{$url}/{$url}.php\">My profile</a>");

?>

 

where you encapsulate your php variables with {} I learned this a while ago, and have been using it ever since. I like it alot better than joining all the stuff together, and in my mind makes it less confusing either way.

nice ty i will remember  that,

 

I just thought of another hyperlink question

 

if im running apache server here at home and I make a link in my page like  http://localhost/something.php,

if click the link and it goes to something.php ,

 

the question is if i allowed people to connect to my home server would i need to change the link to httP://www.sinista.com/something.php

 

or would they be able to use the 1st link??

You need to do some reading about DNS, but no that localhost link will not work for anyone outside your computer.
