Socialengine Tutorial – Disable default css from being loaded

Posted on May 23, 2012 by Andy

I’ve been working on creating a custom homepage which uses twitter bootstrap however I’ve found the default css being generated by the socialengine is interferring with the bootstrap css.

In order to stop socialengine from adding in the default theme css files head to

Application > Modules > Core > Layouts > Scripts > default-simple.tpl

This default simple is what is loaded on every page and then injected with the page’s content. However I didn’t want any of that to load on my landing page so I’ve done the following;

(In this file look for line 75 where the ‘linking’ of css files begins and I’ve wrapped it in an if statement which says if the current url string == the default home page (e.g. /) then don’t bother loading the rest of the php)

<?php // LINK/STYLES ?>
  <?php
  $uri = Zend_Controller_Front::getInstance()->getRequest()->getRequestUri();
  if(trim($uri, '/') !=  trim($this->baseUrl(), '/')):
  ?>
  <?php
    $this->headLink(array(
      'rel' => 'favicon',
      'href' => ( isset($this->layout()->favicon)
        ? $this->baseUrl() . $this->layout()->favicon
        : '/favicon.ico' ),
      'type' => 'image/x-icon'),
      'PREPEND');
    $themes = array();
    if( !empty($this->layout()->themes) ) {
      $themes = $this->layout()->themes;
    } else {
      $themes = array('default');
    }
    foreach( $themes as $theme ) {
      $this->headLink()
        ->prependStylesheet($this->baseUrl().'/application/css.php?request=application/themes/'.$theme.'/theme.css');
    }
    // Process
    foreach( $this->headLink()->getContainer() as $dat ) {
      if( !empty($dat->href) ) {
        if( false === strpos($dat->href, '?') ) {
          $dat->href .= '?c=' . $counter;
        } else {
          $dat->href .= '&c=' . $counter;
        }
      }
    }
  ?>
 
  <?php endif; ?>

Hope this helps 🙂

SocialEngine Tutorial – Modify sign up process

Posted on May 21, 2012 by Andy

I’ve had to modify my sign up process so that I can add in questionnaires before the user signs up and then save the result when the user account is made.

When I first had a google for this, there was literally nothing out there so I’m hoping this will be some use!

First off, what am I on about?

The sign up process is the process that the user is taken through when they click the ‘join here’ button on your login form. This will take them through a series of steps in order to create an account. However just finding the code which handles that process is confusing enough!

Everything is managed under the User module.

The files associated with the sign up process are as follows;

Your forms (using the Zend form builder)
Application > Modules > User > Form > Signup

Here you store your form classes (the classes which extend Engine_Form) for things like questionnaires/profile widgets etc

Sign up Step controllers
Application > Modules > User > Plugin > Signup

Each file here represents a step in the sign up process. Within each file there will be a few methods such as onSubmit, onProcess, onAdminProcess, onView. Within each of these methods you can perform an action e.g. form submission you can validate or save the form details to the database etc.

Each view for your Plugins (sign up steps)
Application > Modules > User > views > Signup > Form

Here you’ll add stuff that the user sees, so it’s your view for each one of the Sign up Step controllers (plugins above). It’l have to share the same name as it’s parent controller in the plugin directory.

Overlord / Main signup process controller
Application > Modules > User > Controllers > SignupController

You’re probably NOT going to want to edit this as it manages the whole process of what’s validated/comes next. The main bulk of your code will be in the plugins (above). However I did edit it so that I could save some session variables to the database once a user had been fully created.

Backend Database ordering
So this is all good and well that you can now add new steps in the sign up controller but how do you order these? If you navigate to the table engine4_user_signup you’ll see that there are rows which show what class is called and what order they are in. You can also disable and enable certain steps in the sign up process.

When creating a new step in the sign up process you have to make sure you add a row in this table and correctly order your step (without duplicate entries in the order list!) the ‘class’ field refers to the name of the class within Application > Modules > User > Plugin > Signup > You Controller Name.

PHP – Extract youtube id from youtube url / link

Posted on April 19, 2012 by Andy

Today I wanted to be able to extract the youtube unique id for the video so that I could automatically embed any youtube video in my webpage.

What I wanted to be able to do was let the user copy + paste in a youtube url such as http://www.youtube.com/watch?v=pJf6S8FYTUo&feature=related and extract the value of the key ‘v’ which is obviously the video id.

After a short while I ran into a stackoverflow question which had an awesomely simple answer;

<?php
$url = "http://www.youtube.com/watch?v=C4kxS1ksqtw&feature=relate";
parse_str( parse_url( $url, PHP_URL_QUERY ), $my_array_of_vars );
echo $my_array_of_vars['v'];    
  // Output: C4kxS1ksqtw
?>

So what this means is that I can now just do the following to embed any youtube video in to a page;

<?php 
$url = "http://www.youtube.com/watch?v=C4kxS1ksqtw&amp;feature=relate"; 
parse_str( parse_url( $url, PHP_URL_QUERY ), $my_array_of_vars ); 
?> 
<i frame src="http://www.youtube.com/embed/<?php echo $my_array_of_vars['v']; ?>" frameborder="0" width="560" height="315">
</i frame>

*remove space between i frame (was to stop it from showing in the post)
