I am trying to learn php and have been going crazy trying to find a solution to what I need to do. I have been googling this and looking at php.net and just can't find what my problem is.

I have to submit a form to a database with name, address and all of the normal things, no problem, I have that part done and works fine.

I would like to have the data the party entered in a new form on a page and then do the following:
Take one field and multiply that by a number, then add that total to another field to get a grand total. I thought that I could get the required fields by using the $_POST array by using:
value= <?php echo $_POST["fname"]?> in the new from field but that is not working. Is this possible?

After the new form is populated a new field will show the grand total by using the values from the array. Am I approaching this correctly? Any suggestions?

Any help or kick in the right direction will be apprectiated.

Yes, it is possible to echo the variable into the value attribute of the new form field, just as you did above.

PHP Code:

<input type="text" value="<?php echo $my_variable; ?>">
or
<input type="text" value="<?php echo $_POST['my_variable']; ?>">
<!-- But please note that you should validate all $_POST data before using it -->

It's probably better if you post your code, together with any error messages you might recieve. Then it'll be easier to spot what's wrong with it.

Try to change this:
value= <?php echo $_POST["fname"]?>
into this:
value= "<?php echo $_POST['fname'];?>"

*Make sure that the name of the text box in the form is raelly: fname

Changing double quotes (") to single quotes (') won't make any difference in this case
