HTML post form with preset variables

I'll try and explain this as best as I can. Basically, I'm using a form to receive a comment. Upon hitting submit, the action creates a link similar to this: http://localhost:8080/camagru/comment.php?comment=test&post=Post

I have a variable with the image name in it that I want to pass as well, so something like this: http://localhost:8080/camagru/comment.php?img=test.png&comment=test&post=Post

I've tried using <form action="<?php echo commentpost.php?img=$img?>"> But everytime the submit button is pressed, it erases the img variable from POST and only puts in the new variables from the form.

Any suggestions?

add new hidden field in form tag like that 

<form action="commentpost.php" method="post">    
    <input type="hidden" value="<?php echo $img ?>" name="img" />
    <input type="submit" value="Save" name="IsSubmit" />
</form>

Now you can able to use $_POST['img']

use quotes in your case:

<form action="<?php echo "commentpost.php?img=$img"; ?>">

the best practice is to insert hidden element into your form:

<input name="img1" type="hidden" value="test.png" /> <input name="img2" type="hidden" value="test2.png" />

The img variable is in GET.

If you want it in POST, try <input type="hidden" name="img" value="test.png">
