wp_dropdown_categories

  • Hi,

    I am working with the wp_dropdown_categories function in wordpress.

    here is the code I am using:

    <form action=”<?php bloginfo(‘url’); ?>” method=”get”>
    <?php wp_dropdown_categories(‘child_of=1&show_count=1&’); ?>
    <?php wp_dropdown_categories(‘child_of=3&show_count=1&’); ?>
    <?php wp_dropdown_categories(‘child_of=4&show_count=1&’); ?>
    <input type=”submit” name=”submit” value=”view” />
    </form>

    Now what this does is show posts from only the last wp_dropdown_categories().

    What I am trying to achieve is that the site user can select from all three drop downs and it would return posts matching all 3 selections , meaning that the posts returned would be in ALL 3 categories. If the post is NOT in ALL 3 of the selected categories it should not be displayed. For example if a post is in one category but not the other 2 it would not display.

    I know next to nothing about php so any guidance at all would be appreciated.

    My thinking is that I need to output the results of each drop down selection into an array that would then be used to populate a wp_list_categories() with the selected categories as arguments.

    Am I on the right track? and if I am, how would I do this? as I have no clue and am stumbling round in the dark here. MY PHP knowledge is barely at beginners level.

    Many thanks for any help with this.

    Ash

    Hi,

    Thanks for your attempt to help, but thats the page I used to get the code in the first place.

    That page DOES NOT show how to have all 3 dropdowns be matched.

    What I am trying to do is to have it so that the user selects from each of the 3 dropdowns and the only posts that are returned are posts that match

      ALL

    3 selections. Right now it returns posts that match the last of the three dropdowns only.

    Maybe the answer is on that page, but if so it requires far more skill with php than i have to identify it. Every example on that page deals with one drop down only. NOT multiple dropdowns.

    Again, thank you, your help is appreciated but I am afraid your answer doesn’t help me and feels more like you just glanced at my question, quickly grabbed the relevant page from the codex and said job done. I say this because if you read my question and the code I showed you would not have given me the answer you did.

    Hi Ash, today I got the same result with dropdown cat’s. Did you solve the problem? Will be very gratefull for solution!

    I don’t see how you can do this. You are posting multiple selects in a single form, where the form action was designed to deal with only one select, hence the behavior your are seeing is normal, at least in the way you are rendering the html with your use of this function…?

    If you want to and the selects together, you need something much more complicated than the functionality provided by this function…
