webref.eu Posted August 19, 2008 Share Posted August 19, 2008 Hi All I am developing a Reviews script where the user gets to choose a Rating Out of 10 via a Dropdown Box as follows: <select name="ReviewRating" id="ReviewRating"> <option>1</option> <option>2</option> <option>3</option> <option>4</option> <option>5</option> <option>6</option> <option>7</option> <option>8</option> <option>9</option> <option>10</option> </select> The script posts back to itself and currently I am then losing the user selected value of this dropdown. So, how do I make the script remember the rating after postback? Please let me know or point me to a tutorial. Many thanks all.

webref.eu Posted August 19, 2008 Author Share Posted August 19, 2008 OK, here is the form in its entirety, sorry about all the commented code and everything but it's still under development. As you can see it's posting back on itself.

thebadbad Posted August 19, 2008 Share Posted August 19, 2008 This should work (swap it with the code in your first post): <select name="ReviewRating" id="ReviewRating"> <?php $rating = (isset($ReviewRating)) ? $ReviewRating : ''; for ($i = 1; $i <= 10; $i++) { $selected = ($rating == $i) ? ' selected="selected"' : ''; echo "<option$selected>$i</option>\n"; } ?> </select> It loops 1 through 10, and adds the HTML attribute selected to the option tag, if the rating matches the number being printed.
