well, i've managed on my own to solve part of the problem now.
This is what i had to do to get the value of the field read into a variable in the php script:
This is in the end of the template i made
HTML Code:
<form action="evaluatetest.php" method="get">
<input type="text" class="bginput" name="quartertime" /></div>
</br>
<input type="submit" class="button" value="Submit / Amend" />
</form>
and this is in the evalueatetest.php file
PHP Code:
$quartertime= $_GET['quartertime'];
Then i can add it to my database from here along with the username and their custom profile field content (which is car make/model).
Still gotta work out how to read values back from my database and populate the table so only half-way there. If anyone has any ideas how to do this please let me know....thanks
