Get tags for current category
On the sidebar of the category template I would like to display the tags associated the current selected category a drop down.
The code I am using is below.
the Problem is the code works sometimes, the ID echoed at the bottom is only correct some of the time. Can anyone say why this is so and how do I fix it?
<select onchange="if(this.options[this.selectedIndex].value != ''){window.top.location.href=this.options[this.selectedIndex].value}" class="modal" >
<?php
global $post;
$category = get_the_category($post->ID);
if ($category[0]) {
$cat_id = $category[0]->term_id;
}
query_posts('cat=' . $cat_id . '&posts_per_page=-1&orderby=title&order=ASC&show_count=0&exclude=7,162,169,163,170,164,165,166,167,168,35,34,33,32,36');
if (have_posts()):
while (have_posts()):
the_post();
$all_tag_objects = get_the_tags();
if ($all_tag_objects) {
foreach ($all_tag_objects as $tag) {
if ($tag->count > 0) {
$all_tag_ids[] = $tag->term_id;
}
}
}
endwhile; endif;
$tag_ids_unique = array_unique($all_tag_ids);
// Now use the following code for displaying the tags list with each tag having its own link.
foreach ($tag_ids_unique as $tag_id) {
$post_tag = get_term($tag_id, 'post_tag');
echo '<option value="?tag=' . $post_tag->slug . '">' . $post_tag->name . '</option>';
}
?>
</select>
<?php echo $cat_id; wp_reset_query(); ?>

<?php
$current_post_tags = wp_get_post_tags($post->ID);
$post_tags_link .= '<ul class="post-tags-link">';
for($i=0; $i < count($current_post_tags ); $i++) {

xhanubis says:Hi Rashad,
Thanks for the quick response. the $cat_name variable needs to be dynamic, not hard coded. Also the snippet for the single post sidebar needs to return all the tags of the category that the post belongs to, NOT just the tag of the current post. - 07/23/12 2:33am
Rashad Aliyev says:Then you can use :

or

Arnav Joy says:try replacing your query_posts with this
query_posts("cat=" . get_query_var('cat'). "&posts_per_page=-1&orderby=title&order=ASC&show_count=0&exclude=7,162,169,163,170,164,165,166,167,168,35,34,33,32,36"); - 07/24/12 3:33am
Arnav Joy says:what you are using is of single page so when you use this
$category = get_the_category($post->ID);
it will show you the correct result when you are in single page but on the category page it will not give you correct result..
what you can do to test that if you are on single page or in category page
so lets try this
<?php
if(is_single()) {
global $post;
$category = get_the_category($post->ID);
if ($category[0]) {
$cat_id = $category[0]->term_id;
}
}
elseif(is_category()) {
$cat_id = get_query_var('cat');
}
query_posts('cat=' . $cat_id . '&posts_per_page=-1&orderby=title&order=ASC&show_count=0&exclude=7,162,169,163,170,164,165,166,167,168,35,34,33,32,36');
if (have_posts()):
while (have_posts()):
the_post();
$all_tag_objects = get_the_tags();
if ($all_tag_objects) {
foreach ($all_tag_objects as $tag) {
if ($tag->count > 0) {
$all_tag_ids[] = $tag->term_id;
}
}
}
endwhile; endif;
$tag_ids_unique = array_unique($all_tag_ids);
// Now use the following code for displaying the tags list with each tag having its own link.
foreach ($tag_ids_unique as $tag_id) {
$post_tag = get_term($tag_id, 'post_tag');
echo '<option value="?tag=' . $post_tag->slug . '">' . $post_tag->name . '</option>';
}
?> - 07/24/12 4:03am
xhanubis says:Works great on the category page...replacing the query solved the issue. I will vote that you get paid the full amount thank you. The code with the if statement does not work on the single page but I will put that in another question if needs be.

You can combine the following snippet with any of the answers above (you need to add at the start)
global $wp_query;
$current_category = $wp_query->get_queried_object();
$current_category_name = $current_category->name;
query_posts('category_name='.$current_category_name);
<?php
global $wp_query;
$current_category = $wp_query->get_queried_object();
$current_category_name = $current_category->name;
query_posts('category_name='.$current_category_name);
if (have_posts()) : while (have_posts()) : the_post();
$posttags = get_the_tags();
if ($posttags) {
foreach($posttags as $tag) {
$all_tags[] = $tag->term_id;
}
}
endwhile;
endif;
$tags_arr = array_unique($all_tags);
$tags_str = implode(",", $tags_arr);
$args = array(
'smallest' => 12,
'largest' => 12,
'unit' => 'px',
'number' => 0,
'format' => 'list',
'include' => $tags_str
);
wp_tag_cloud($args);

After pasting it to functions.php and saving, drag the widget (Appearances->Widgets) to your desired sidebar.Previous versions of this answer: 07/23/12 at 2:46am | 07/23/12 at 2:46am | 07/23/12 at 2:54am | 07/23/12 at 2:56am

The closest thing so far is this code...but for some reason it works on one category but not on the others.

xhanubis says:That cause my code to stop returning tags all together. I have set the original code to echo the category from what I see its not updating the category when I change category. I start with category 3 and no matter which category I click it still echo 3.
- 07/23/12 5:08am
AdamGold says:ah I see, so change:
<select
to:
<form method="POST" action=""><select name="category_select">
Change:
if ($category[0]) {
$cat_id = $category[0]->term_id;
}
to:
if ($category[0]) {
$cat_id = $category[$_POST['category_select']]->term_id;
}
And add after </select>:
<input type="submit" name="submit" value="Change" /></form>
