I don't know how i can do that through php using mysql. i studied from http://phproots.com php tutorial.
The easiest way for you to do this IF you have PHP/SQL knowledge is: Allow the users to pick which form they need to use from either a drop-down select box or links. When they pick their form, it will send a submission value (example) <option value="form_1"> Form for Such and such </option> <option value="form_2"> Form for Next such and such </option> then submit by standard button form <input type="submit" value="Submit" onclick="this.form.submit"> have this send it to the same page in the <form name="index.php method="post" action="index.php"> (or whichever page you're using for this function. Once it resends the data that page should have php script at the top to catch them <?php $form_selected = $_POST['form_selector']; // this would then allow the value of 1- 100 (as many forms as you have) to grab a form from a folder/file and display it on that page. with a PHP code in the body of your page that is something such as <?php if($_POST['form_selector']) { $form_display = "Forms/form_" . $form_selected . ".php"; include($form_display); } ?> ..to have the form displayed. Or use AJAX so that as fast as the user clicks the form they need , it appears to the right. This would be the most aesthetic and fastest/smoothest option. IM me for details on that
