How to query specific categories

  • Could someone help me out, I’m a beginner with php, so bare with me ??
    Is it possible to query, display just a particular category on a page?
    For instance:
    index.php would display all the posts under the General category.
    about.php would display all the posts for the About category… and so on.
    I’m hoping this can be accomplished with a simple query on each page.
    Now I know there is a hack that will allow me to display just one category on the index page,
    But that only solves half of what I’d like to do.
    So I hope I’m being clear here on what it is I’m looking to do.

  • You could copy index.php to about.php, then use the hack to restrict about.php to one category:
    $cat = '2';
    Or, if mod_rewrite is enabled on your web server, you could create a rewrite rule that serves up “index.php?cat=2” when a visitor requests about.php.

    I followed these directions:

    It’s not working, at all.
    Here is the function I’m trying:
    <?php
    if (‘/’ == $_SERVER[‘REQUEST_URI’])
    $cat = 1;
    ?>
    I’ve tried it with a my-hacks.php file, and by simply adding the code to the index page.
    Thanks for the help.

    I have figured it out.
    I only needed the $cat = 1; and placed it just before the $blog = 1; on the index.php page:
    Like so:
    <?php
    /* Don’t remove these lines. */
    $cat = “4”;
    $blog = 1;
    require(‘wp-blog-header.php’);
    // Uncomment the next line if you want to track blog updates from weblogs.com
    //include_once(ABSPATH.WPINC.’/links-update-xml.php’);
    ?>

    Hi, I’ve just implemented the hack on my wp, and I found that if you exclude everything except the $cat =1; line, the index page displays only the general category. I’ve also found that this does not affect the other categories. I believe that this is because the REQUEST_URI does not match ‘/’ (perhaps match ‘/’ or ‘/index.php’?). Try leaving off the index.php in your url. It might work. To fix this, either comment out all of the lines except for $cat=1; or change:
    if ('/' == $_SERVER['REQUEST_URI'])
    to:
    if (('/' == $_SERVER['REQUEST_URI'])||('/index.php' == $_SERVER['REQUEST_URI']))
    Hope that helps!

    See this post from me about how to exclude a category unless it is specifically requested. You could easily use this same process to restrict the default output to a single category.
    if (empty($_GET['cat'])) $cat = '4';
    Again, I suggest putting this in wp-blog-header.php.
