    The 10-second explanation of my problem: I run a Wordpress CMS with a stylesheet that looks great I installed a forum plugin that has dull styling There are CSS stylesheets specific to this plugin that look great, but when they are installed they change the entire Wordpress theme Can I run two stylesheets at once pointing at the same page? One would control the mother Wordpress theme and the other would control the elements specific to the forum plugin. If so, what happens when there is a "#content" class on each sheet? Can't they both just get along?? My code structure looks like this: [HEADER] <div id="container"> <div id="content"> [PAGE CONTENT] <div id="box"> <div id="containingdivfortheforum"> [FORUM PLUGIN CODE] </div> </div> </div> <div id="sidebar"> [sIDEBAR CONTENT] </div> </div> [FOOTER]

    Hey that worked thanks!

    Hmm placing global $form; there didn't help the data make it to the table :-\
  4. dslax27
    Where would that global go exactly (please excuse my noobness)? I tried this: $submitname = $this->getValue(global $form['name'], 'No Name Entered'); $submitemail = $this->getValue(global $form['email'], 'No Email Entered'); $submitcountry = $this->getValue(global $form['country'], 'No Country Entered'); but that returned with errors.

    Hey gang. I'm working with a nice little multi-step form wizard from http://www.phpriot.com/articles/multi-step-wizards/1. When the user completes the form, I'd like the data to be stored to a database. I added a new function called "function post2db": function post2db($name, $type, $number) { // communicate with CC gateway here $user = "root"; $password = ""; $database = "doug_db"; $db_address = "localhost"; $dbh = mysql_connect( $db_address, $user, $password ) or die ('I cannot connect to the database because: ' . mysql_error()); $dbh = mysql_select_db( $database ) or die('cannot select db'); //echo "<br>".$dbh; $submitname = $this->getValue($form['name'], 'No Name Entered'); $submitemail = $this->getValue($form['email'], 'No Email Entered'); $submitcountry = $this->getValue($form['country'], 'No Country Entered'); $query = "INSERT INTO dougtable (id, name, email)"; $query .= "VALUES ('', '".$submitname."', '".$submitemail."')"; $dbh = mysql_query( $query ) or die('failed insert query'); //echo "<br>".$dbh; echo "<br><br>Your name is: ".$name; $dbh = mysql_close() or die('something bad happened during myqsl_close'); } You'll see that I want the data from $submitname = $this->getValue($form['name'], 'No Name Entered'); to populate from whatever the user entered into the wizard into my database. The form functions without error; however, it does not post the information to the database I created :-\. Any ideas? Here's the complete code: My index.php code: <?php require_once('CheckoutWizard.class.php'); $wizard = new CheckoutWizard(); $action = $wizard->coalesce($_GET['action']); $wizard->process($action, $_POST, $_SERVER['REQUEST_METHOD'] == 'POST'); // only processes the form if it was posted. this way, we // can allow people to refresh the page without resubmitting // form data ?> <html> <head> <title>phpRiot() wizard example</title> </head> <body> <h1>phpRiot() wizard example</h1> <?php if ($wizard->isComplete()) { ?> <p> The form is now complete.

    Cool I'll get started with w3schools and youtube!

    Would I need to read an entire book to understand what this tutorial is trying to teach(http://www.phpriot.com/articles/multi-step-wizards/1)? I think one of my biggest hurdles is understanding the relationship between the code and the database in my form example. Do I create the database table first and then have the code call on the table or vice versa?

    I've read a lot of form / survey tutorials and forum posts over the past few days and I'm learning quite a bit. One problem: I am completely new to PHP, and unfortunately everything I've read assumes otherwise. My first PHP goal is to set up a form that perform the following actions: Save user data to a PHP database E-mail me a synopsis of each user's entry Show the user a confirmation of what they've submitted Any suggestions as to where should I get started? Would I be better off using a site like POG (http://www.phpobjectgenerator.com) since I am so new?

    Hello! Complete noob here, but I did my homework before posting so don't yell at me too much please haha! My Goal: Create a simple multi-step form that both saves the data in a database and E-mails me a copy. What I've gathered so far: According to http://www.phpfreaks.com/forums/index.php/topic,119933.0.html it seems the best route for a multi-step (or multi-page) form is to use temporary tables in my database instead of extending the url as the user moves along. I found a solid example here: http://www.phpriot.com/articles/multi-step-wizards/5 Front End: <?php require_once('CheckoutWizard.class.php'); $wizard = new CheckoutWizard(); $action = $wizard->coalesce($_GET['action']); $wizard->process($action, $_POST, $_SERVER['REQUEST_METHOD'] == 'POST'); // only processes the form if it was posted. this way, we // can allow people to refresh the page without resubmitting // form data ?> <html> <head> <title>phpRiot() wizard example</title> </head> <body> <h1>phpRiot() wizard example</h1> <?php if ($wizard->isComplete()) { ?> <p> The form is now complete. Clicking the button below will clear the container and start again. </p> <form method="post" action="<?= $_SERVER['PHP_SELF'] ?>?action=<?= $wizard->resetAction ?>"> <input type="submit" value="Start again" /> </form> <?php } else { ?> <form method="post" action="<?= $_SERVER['PHP_SELF'] ?>?action=<?= $wizard->getStepName() ?>"> <h2><?= $wizard->getStepProperty('title') ?></h2> <?php if ($wizard->getStepName() == 'userdetails') { ?> <table> <tr> <td>Name:</td> <td> <input type="text" name="name" value="<?= htmlSpecialChars($wizard->getValue('name')) ?>" /> </td> <td> <?php if ($wizard->isError('name')) { ?> <?= $wizard->getError('name') ?> <?php } ?> </td> </tr> <tr> <td>Email:</td> <td> <input type="text" name="email" value="<?= htmlSpecialChars($wizard->getValue('email')) ?>" /> </td> <td> <?php if ($wizard->isError('email')) { ?> <?= $wizard->getError('email') ?> <?php } ?> </td> </tr> <tr> <td>Country:</td> <td> <select name="country"> <option value=""></option> <?php foreach ($wizard->countries as $k => $v) { ?> <option value="<?= $k ?>"<?php if ($wizard->getValue('country') == $k) { ?> selected="selected"<?php } ?>> <?= $v ?> </option> <?php } ?> </select> </td> <td> <?php if ($wizard->isError('country')) { ?> <?= $wizard->getError('country') ?> <?php } ?> </td> </tr> </table> <?php } else if ($wizard->getStepName() == 'billingdetails') { ?> <table> <tr> <td>Credit Card Type:</td> <td> <select name="cc_type"> <option value=""></option> <?php foreach ($wizard->ccTypes as $v) { ?> <option value="<?= $v ?>"<?php if ($wizard->getValue('cc_type') == $v) { ?> selected="selected"<?php } ?>> <?= $v ?> </option> <?php } ?> </select> </td> <td> <?php if ($wizard->isError('cc_type')) { ?> <?= $wizard->getError('cc_type') ?> <?php } ?> </td> </tr> <tr> <td>Credit Card Number:</td> <td> <input type="text" name="cc_number" value="<?= htmlSpecialChars($wizard->getValue('cc_number')) ?>" /> </td> <td> <?php if ($wizard->isError('cc_number')) { ?> <?= $wizard->getError('cc_number') ?> <?php } ?> </td> </tr> </table> <?php } else if ($wizard->getStepName() == 'confirm') { ?> <p> Please verify the entered details and then click next to complete your order. </p> <table> <tr> <td>Name:</td> <td><?= $wizard->getValue('name') ?></td> </tr> <tr> <td>Email:</td> <td><?= $wizard->getValue('email') ?></td> </tr> <tr> <td>Credit Card Type:</td> <td><?= $wizard->getValue('cc_type') ?></td> </tr> <tr> <td>Credit Card Number:</td> <td><?= $wizard->getValue('cc_number') ?></td> </tr> </table> <?php } ?> <p> <input type="submit" name="previous" value="<< Previous"<?php if ($wizard->isFirstStep()) { ?> /> <input type="submit" value="<?= $wizard->isLastStep() ?

How would I implement the above code? In other words, where do I save the backend? Unfortunately my php experience is limited to CMS packages that do all the installation for me. 2. Once the user hits the final "submit" button, how can I have the data both save into a database and E-mail me a copy? Thanks and let me know if you need further explanation
