Dropdown in custom post-type list to filter taxonomy + showcount WordPress

  • SOLVED

Hello,

I'm after a function please to simply do exactly what the category drop down does in posts.

I need the dropdown filter to appear here... [[LINK href="http://i.imgur.com/rlmP1.png"]]http://i.imgur.com/rlmP1.png[[/LINK]]

and the dropdown filter to appear in multiple post-types...

<strong>on-road</strong>
<strong>off-road</strong>


And the taxonomy is called... <strong>year</strong>


This is what I got to but 'show_count' is got from all both post-types, and the filter doesnt actually work. Plus it only shows in on-road.

Can any one please help, money goes to fully working function.




// CUSTOM TAXONOMY FOR YEAR- AS A DROP DOWN IN POST-TYPE on-road AND off-road
function pippin_add_taxonomy_filters() {
global $typenow;

// an array of all the taxonomyies you want to display. Use the taxonomy name or slug
$taxonomies = array('year');

// must set this to the post type you want the filter(s) displayed on
if( $typenow == 'on-road' ){

foreach ($taxonomies as $tax_slug) {
$tax_obj = get_taxonomy($tax_slug);
$tax_name = $tax_obj->labels->name;
$terms = get_terms($tax_slug);
if(count($terms) > 0) {
echo "<select name='$tax_slug' id='$tax_slug' class='postform'>";
echo "<option value=''>Show All $tax_name</option>";
foreach ($terms as $term) {
echo '<option value='. $term->slug, $_GET[$tax_slug] == $term->slug ? ' selected="selected"' : '','>' . $term->name .' (' . $term->count .')</option>';
}
echo "</select>";
}
}
}
}
add_action( 'restrict_manage_posts', 'pippin_add_taxonomy_filters' );






Thanks
Josh

'year' is a WP reserved term, and you should not use it, to avoid unexpected behaviour.

First change your taxonomy name (you may need to reassign all terms to the new taxonomy), then re-save your peramlink structrue, update your function to use the new taxonomy name, and then check.
I had similar issue with 'year' taxonomy, changing the name solved all issues.

Sorry for late reply, lots of other stuff going on.

Anyway, thanks for making realise about the reserved terms. I have modified now and seems to be working.

Though I guess the the show count will always count the entirety of posts assigned to that term. So it's impossible to count the posts specifically to on either on-road or off-road.


// CUSTOM TAXONOMY FOR YEAR- AS A DROP DOWN IN POST-TYPE
function pippin_add_taxonomy_filters() {
global $typenow;

// an array of all the taxonomyies you want to display. Use the taxonomy name or slug
$taxonomies = array('model-year');

// must set this to the post type you want the filter(s) displayed on
if( $typenow == ( 'on-road' || 'off-road' )){

foreach ($taxonomies as $tax_slug) {

$tax_obj = get_taxonomy($tax_slug);
$tax_name = $tax_obj->labels->name;
$terms = get_terms($tax_slug);

if(count($terms) > 0) {

echo "<select name='$tax_slug' id='$tax_slug' class='postform'>";
echo "<option value=''>Filter $tax_name</option>";
foreach ($terms as $term) {
echo '<option value='. $term->slug, $_GET[$tax_slug] == $term->slug ? ' selected="selected"' : '','>' . $term->name .' (' . $term->count .')</option>';
}
echo "</select>";
