a:
make sure not to copy/paste anything with squint quotation marks.
only use '
and "
b:
http://codex.wordpress.org/Function_Reference/get_tag_link
having an array with only tag names makes this more difficult.
try to change this section:
$all_tags_arr[] = $tag -> name;
to:
$all_tags_arr[] = $tag;
then this might work:
foreach ($tags_arr as $tag) {
echo '<li><a href="' . get_tag_link($tag->term_id) . '">' . $tag->name . '</a></li>';
}
don’t forget the <ul>
tags
(untested)
Thank you, however I think I’m having the same problem knowing how to apply these edits. I don’t know where to add the
foreach ($tags_arr as $tag) {
echo '<li><a href="' . get_tag_link($tag->term_id) . '">' . $tag->name . '</a></li>';
}
Do I replace part of the original code or add this at the end?
Sorry about the “squint quotation marks”, I don’t know what that is or why it’s wrong but hopefully I won’t do it again.
This is what I tried
<?php
query_posts('category_name=uncategorized');
if (have_posts()) : while (have_posts()) : the_post();
$posttags = get_the_tags();
if ($posttags) {
foreach ($tags_arr as $tag) {
echo '<li><a href="' . get_tag_link($tag->term_id) . '">' . $tag->name . '</a></li>';
}
}
endwhile; endif;
$tags_arr = array_unique($all_tags_arr); //REMOVES DUPLICATES
echo '<pre>'.print_r($tags_arr, true).'</pre>'; //OUTPUT FINAL TAGS FROM CATEGORY
?>
this is the error:
Warning: Invalid argument supplied for foreach() in /home2/fourstic/public_html/TravelBlog3000/wp-content/plugins/wp-php-widget/wp-php-widget.php(52) : eval()’d code on line 6
So I don’t know if it works because I don’t know if I’m doing what you intended with your suggestion. I obviously don’t understand the functions involved here or how it’s working, so It’s all trial and error for me.
my idea $all_tags_arr[] = $tag;
did not work.
general, the foreach loop would replace the print_r line of your code.
first step, build an array of tag ids; then make them unique; then output them in the froeach loop, getting the name from the id.
this seems to be working:

about the ‘squint’ quotation marks:
this is what you posted:
echo “<li>”.$tag.”</li>”;
see the quotation marks, probably made this way by a text editor.
these would not work in code.
they should read like this:
echo "<li>".$tag."</li>";
Thanks so much, yes it works perfectly, I’ve been struggling with this for weeks.
I think I understand about replacing the print_r with the foreach. I was under the impression that an array had to use print_r.
You really made my day, thanks again!
I understand now that squint quotation marks are different than the ones in code, but I wouldn’t know how to use one instead of the other, My keyboard only has one kind which I use for everything. I don’t know why they don’t come out right in the forums sometimes. My apologies.

and that is perfect so – these are the right ones to use in coding.
the other ones are usually made by text processors to make the text ‘look better’ – unfortunately also somtimes in articles that share code.
