How to add PHP variables to a href url

Question

Im trying to add a PHP variable to a href url

This is the code:

PHP

$uid= $_SESSION['userid'];

HTML

<a href=http://example.com/uid= <?php echo ".$uid."?> /a>

How do you add, when I do it, this is what it redirect too: http://example.com/uid=.

Solution 1

Try this,

<?php
@session_start();
$uid= $_SESSION['userid'];
?>
<a href="http://example.com/?uid=<?php echo $uid; ?>" >Your link text</a> 

Solution 2

echo "<a href=\"http://example.com/?uid=$uid\">link description</a>";

Solution 3

Perhaps something like this:

print '<a href=http://example.com/?uid=' . $uid . '>Link</a>';

Solution 4

This is one of the most helpful

echo "<td>".($tripId != null ? "<a target=\"_blank\"href=\"http://www.rooms.com/r/trip/".$tripId."\">".$tripId."</a>" : "-")."</td>";

It will work!

Solution 5

try this

<?php 
$url = 'https://www.w3schools.com/php/';
?>

<a href="<?php echo $url;?>">PHP 5 Tutorial</a>

Or for PHP 5.4+ (<?= is the PHP short echo tag):
<a href="<?= $url ?>">PHP 5 Tutorial</a>

or 
echo '<a href="' . $url . '">PHP 5 Tutorial</a>';

Make sure you have session_start() at the top of your script, and the syntax should look like <a href="http://example.com/uid=<?php echo $uid; ?>">...</a>

Your syntax is broken. You want to get rid of the quotes inside the PHP part (but wrap the entire href attribute in them)

<a href="example.com/uid= <?php echo $uid?"></a>

This depends ENTIRELY on how you're using that html. Is it being assigned to a php string? Then echo is the totally wrong tool. Is it direct output "out" of php mode? Then it'd work, if you fixed your html syntax.

@user3245415 you're supposed to pick the answer that helps you most at some point. Are you still stuck on this?

[Jack]

Syntax is wrong - missing closing bracket for a tag and the double-quote isn't needed.
