I have a custom post type, "entrepreneurs", with a custom taxonomy, "sectors" attached to it. Here is the code (http://codepad.org/ceQH4a6a) for my custom post type registrations.

Things you might need to know:

  • "Entrepreneurs" are heirachical, like pages.
  • "Sectors" are like the categories for the post type


What I want to do...

In both my archive and single views, I would like to display the assigned sector name for the post below the title - in the same way that you would in, say, a blog article, using "the_category" or something similar. Like so:

<?php the_category('', '', $post_id) ?>


The full block of code can be found here (http://codepad.org/ub3c9N9P).

I want the H4 to output the custom taxonomy, without a link - resulting in the following layout (http://db.tt/xiL3w0ty). The grey text below the title is sector taxonomy.

I've tried a number of solutions found on various forums and resources, but none are working for me. Any help would be appreciated.

Thanks in advance.
]]> WooCommerce - Display all product variations on Shop Index page? http://www.css-tricks.com/forums/discussion/25232/woocommerce-display-all-product-variations-on-shop-index-page Sat, 25 May 2013 07:55:53 -0400 croydon86 25232@/forums/discussions Hi all

I would like to know if there was a way to display different product variations of the same product as separate items in the Shop Index/category page.

For example, lets say I create a product, a Tshirt that comes in white and black. I create this as one product with two colour options.

Currently, in the main Shop index, this displays only the default colour I set (black). I would like to display both the black and white options, so when the user clicks on either, they will be taken to the same page.

The only way I can think of (which I would like to avoid) is to create them as two separate products.

Is there a better way to do this?

Thanks in advance

Ive been wrastling with this for a few hours now and i am in much need of help. ive tried all diff kinds of things.

i am using wordpress and i am also using the custom post types plugin and custom post types ui plugin.

the custom field i am trying to grab the date from and use to compare is called "date_of_event" and it is being created with the datepicker.

if you want to see a live version of what i have now it is indeed live on my server and its working as far as grabing the custom post type and displaying the date chosen by the date picker in the correct ASC order n stuff but for dates that have passed they are still showing as i have not written any logic to do so. this is what im having trouble with. this is the link --> http://domenicocolandrea.com/tiki-bar/

also if you want to see what my code looks like a link to a .php file of the exact page is here --> https://www.dropbox.com/s/64zjakrkgtai1mn/eventsHELP.php

I have set up a wp_nav_menu in Wordpress. I have 2 parent categories, with 2 sub-categories each, so this produces a nested list.

My current code to call this menu is...

<?php wp_nav_menu( 
          array( 
              'theme_location'    =>  'shop-categories',

              'container_class'   =>  'shop-cat'
          ) 
      ); ?>

... which outputs this...

(I have simplified the code so you just get an idea of the markup)

<nav class="shop-cat">
  <ul>
    <li>
      <a>Clothing</a>
      <ul>
        <li><a>T-Shirts</a></li>

        <li><a>Hats</a></li>
      </ul>
    </li>
  </ul>
</nav>

Now I would like to output this...

<select>
  <optgroup label="Clothing">
    <option value="T-Shirts">T-Shirts</option>
    <option value="Tops">Tops</option>
  </optgroup>
  <optgroup label="Accessories">
    <option value="Earings">Earings</option>
    <option value="Hats">Hats</option>
  </optgroup>
</select>

...is this possible to do dynamically? Or will it be better to do this manually? I have had a look around but couldn't find any help on this.

Any help appreciated.

I want everything after mydomain.com/ should be handled as ?page=

This is how far I've got so far in my .htaccess

DirectoryIndex index.php
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]*)(.*) index.php?page=$1  [NC,L]

And it works pretty well if write /login my pagehandler catch it as ?page=login but if you write an existing filename it doesn't work. Example: mydomain.com/folder becomes mydomain.com/folder/ (adds a slash after) Or if you write: mydomain.com/file.php it loads that php file but i want it not to. I want it to be handled as ?page=file.php

And i guess this may lead to problems linking to css, and js, if it does and you have any suggestions on how to solve that as well i would be very thankfull.

I hope I'm not to confusing for you guys. and thanks in advance for any help you can provide.

I came across the hNews Microformat of the "html5 reset" theme. I am using the loop as a template part that I can add where needed. My question is less of a php issue I guess, but more of a semantic issue.

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

  <article <?php post_class() ?> id="post-<?php the_ID(); ?>">

    <h1 class="entry-title"><?php the_title(); ?></h1>

    </div>

    <?php edit_post_link(__('Edit this entry'),'','.'); ?>

  </article>

 <?php comments_template(); ?>

<?php endwhile; endif; ?>

If I use the article tag, is it okay to use this format to post pages also, or should I have another loop that will display the pages in a div rather than an article?

]]> Limit WordPress URL length http://www.css-tricks.com/forums/discussion/14795/limit-wordpress-url-length Tue, 29 Nov 2011 11:58:04 -0500 Johnnyb 14795@/forums/discussions
I'm working on a rebuild of a site and trying to keep the new URL's the same as the old ones. The old ones just use the post name but they appear to be limited to a certain number of characters, for example:
www.example.com/news/boston-meets-with-life-sciences-economic-development-organization-from-

The new URL generated by WordPress looks like this:
www.example.com/news/boston-meets-with-life-sciences-economic-development-organization-from-europe/

I know I can edit the permalink manually via the post editor, but as there are a lot of posts involved then I'm wondering if there's a way to limit the URL (to 100 characters for example) automatically?

Any nudge in the right direction would be much appreciated!

They use only four colors (red, green, blue, yellow). We would like to create a page in which the background color changes to that week's color. I am sure this is simple but I am still new to PHP and am trying to automate trivial things like this as best as possible.

Thanks in advanced for your help.

In that, there was a common Header.php for all files and a footer.php. Now as i am starting to create a new PHP based Forum then

  1. Should I use a common Header.php and Footer.php
  2. I want to create a fluid Layout so is it ok to use Boilerplate.css [Dreamweaver's Fluid Design option]
  3. Should i design the whole site in html and then convert it to PHP

Really need suggestions, and I know that this is the best place to get it.

]]> Friendly URL | GET parameters lost http://www.css-tricks.com/forums/discussion/24832/friendly-url-get-parameters-lost Sun, 12 May 2013 05:55:28 -0400 AndrewPham 24832@/forums/discussions Let's say I have a website : example.com

And a webpage: example.com/page.php

I want to make it more friendly, so I use .htaccess: example.com/page

Which contains links to other "pages". They are actually the same one, the only difference being the GET parameters from the URL, which would pull different content from the database.

So by clicking the links within "page.php", wether you're on "example.com/page.php" or "example.com/page", you'll get to "example.com/page.php?category=design&page=3&lang=ro"

I want to make it more friendly too, so I use, again, .htaccess. The result would be "example.com/page", followed by all those values, separated by slashes: "example.com/page/design/3/ro"

My question is: Within the page.php file, how on earth am I going to be able to make use of the GET parameters??

$_GET["category"] or $_GET["page"] wouldn't work, at least in my case. Does it work for you? It isn't even logical to work. There is no "category" or "page" parameter in the URL. So when attempting to write $_GET["category"], the server will analize the URL and it will need the actual parameter NAME as well as the VALUE. In our case, we only have the value. Someone, please fill me in?
