    Does anyone know how get the following code to also apply to a category post as well? 

    <div id="header-logo" onclick="location.href='<?php bloginfo('url'); ?>'" style="cursor: pointer;" >
<?php if (is_page(array('1', '2', '3','4', '5', '6', '7', '7'))) $logo_image = 'subLogo.jpg';
else $logo_image = 'mainLogo.jpg';?>
<img src="<?php bloginfo('stylesheet_directory'); ?>/images/<?php echo $logo_image;?>" alt="<?php bloginfo('name'); ?>" />
</div>

    Thanks

  • Personally, I wouldn’t do it like that – there’s a far simpler way of doing it using CSS. But, only if your theme adds semantic classes to your <body>.

    Using these semantic classes you can change the style of objects depending on which page you’re viewing. Your logo could then be displayed using a background image rather than an IMG tag.

    For example, in your header.php file your would have:

    <div id="logo"></div>

    In your CSS you would then have:

    #logo {background: url(mainLogo.jpg);} /* for all other pages */
.pageid-1 #logo, pageid-2 #logo, pageid-3 #logo, catid-23 #logo {background: url(subLogo.jpg);} /* for the pages you want to change */

    These CSS classes might be different in your theme, so just have a look at the pages in your browser and look at the source to see what they should be.

    Hope that helps

    Thanks for your post Peter,

    I see what your saying, I’m using Twenty Ten as a child theme and I think it use’s it’s own (crazy) semantic classes to the body tag i.e.

    <body class="single single-post postid-393 single-format-standard logged-in admin-bar">

    I suppose there’s a way I could get it to stop doing that and add my own classes, I might look in to that too.

    Yeah, so you’ve got the postid-393, which is the unique identifier for that particular post. How about if you’re viewing a category post? It might have something like catid-5 or something (I tend not to use categories to differentiate my posts, so I can’t be sure!)

    If you want to see the principle in action, have a look at this site of mine: planetearthinstituteworldwide.org – I use this method to change the background image of the whole page depending on the section you’re viewing as well as the heading colours to match (click your way through the menus top menus to see).

    Have fun!

    check either
    in_category() (for single posts)
    or
    is_category() (for category archive pages)

    Thanks alchymyth, and Peter,

    Had a look the wordpress codex, bit above my level of understanding when trying to combine my code with that. Think I’m going to try and add a second header and add
    include(STYLESHEETPATH."/header2.php");?>
    to the relevant categories.

    There is a simpler way as the get_header() function accepts a name, which will call in an alternative header file.

    eg – get_header() loads the standard header.php but get_header('home') will load header-home.php

    Thanks petervandoorn, I tried the get_header(‘header2’) thing but it just didn’t seem to work at all, the include(STYLES-yada, yada, yada bit works ok though, just need to change one css element for the logo and it’s done.

    Did you get the name of the header .php file right? get_header('header2') would look for a file called header-header2.php!

    Yea sorry should have put down get_header( $header2 ); ?>
