Insert a php variable into my html url

Question

Hi I am trying to add my php variable $remove into the query string so that when the submit button is pushed the action that happens is a request made to remove_friend_db.php?user= where user = contained the value of $remove.

while ($row = $result->fetch_row())
{
    echo "<img src='images/$row[0]_thumb.jpg' atl='userThumbnail'>";
    echo "$row[1] $row[2] $row[3]";
    $remove= $row[0];
    ?>
    <form method="GET" action="remove_friend_db.php?remove="<?php "$remove">"">
    <input type="submit" value="Remove Friend">
    </form>
    <?php
}

$remove is aways blank?

<?php echo $remove ?>... You're not outputting anything. you're just basically saying "here's a variable" and php's going "ok, whatever".

I am not sure why you are using this technique.
If you want to use Form then make a input field and then send it to the file.

<form method="GET" action="remove_friend_db.php">
    <input type="hidden" name="" id="" value="<?php echo $remove; ?>" />
    <input type="submit" value="Remove Friend">
</form>

But type="text" name=""would show up a text field in the html form.

Make it hidden type="hidden"

You should also be able to do it via an hidden input field. Something like this should work ...

while ($row = $result->fetch_row())
{
    echo "<img src='images/$row[0]_thumb.jpg' atl='userThumbnail'>";
    echo "$row[1] $row[2] $row[3]";
    $remove= $row[0];
  ?>
    <form method="GET" action="remove_friend_db.php">
    <input type="hidden" name="remove" value="<?php $remove ?>">
    <input type="submit" value="Remove Friend">
    </form>
  <?php
}

$remove is not inside php tags, it will print as is. $remove

@AlexAndrei yes you're absolutely right. Fixed it in the answer. Thanks for the comment.

If you turn on short tags (in php.ini), which are great for templating, you can do the following:

value="<?=$remove?>"
