getting span id in php?

[techker]

Hey guys i got an invoice form that has the totals in a span id

 

 

        SUB ::<span id="small_total"></span><br />
        TPS :: <span id="tps"></span><br />
        TVQ :: <span id="tvq"></span><br />
        GRAND TOTAL :: <span id="grand_total"></span><br />
 
 

 

so its part of a form,when i submit to add to databse i can't seem to figure out how to get the values of the id?

 

i have tried a few things with no success..

 

exp

in the add.php page(form submit action)

$GT = "<script language='javascript'>document.getElementById(grand_total);</script>";

things you display on a web page are just for display purposes. if you need the total on the server, you should calculate it from the original source data values so that someone cannot alter the DOM in the browser and submit any value they want to your server-side code.

If you are submitting the form without JavaScript, the way you are doing it is not possible.  Why not just wrap it in a <form>?

If you want it accessible through a form and still seen in your span, you'll have to add it to a hidden input.

 

 

<input type="hidden" name="grand_total" value="grand_total_amount_here">

 

Either way it will still be editable by a user.  The only way to do it securely would be to follow mac_gyver's advice.
