    The most scalable way to use two styles?

    in CSS Help

    Posted

    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>

    Noob - adding a new function

    in PHP Coding Help

    Posted

    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.

     

     

    Noob - adding a new function

    in PHP Coding Help

    Posted

    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. Clicking the button below will clear the container and start again.

    Nooob alert! Simple, beginners table question

    in PHP Coding Help

    Posted

    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?

     

    Multi-step form w/E-mail

    in PHP Coding Help

    Posted

    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:

     

     

    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

?>

    Questions:

    1. 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
