I’m not sure that this is an ideal solution for the issue above, but for anyone else experiencing this same issue, I’ve found that the “Missing argument 1 for in_category() in _____/category-template.php” error arose from the set-up of the conditional tags within the sidebar.

Originally, I had employed the following code:

<div class="sidebar">
<?php if ( is_404() || is_category() || in_category() || is_single() || is_day() || is_month() || is_year() || is_search() || is_paged() || is_page() ) { ?>
...

This code enabled any of those conditions within the sidebar (the code goes on to lists specific content for any of the individual conditions, such as

<?php /* } elseif (is_category('1')) { ?>
<h3>Headline/Content Here</h3>

etc.)

Although the other conditional tags were operating correctly with the empty arguments (such as “is_category()”), the empty “in_category()” in that opening
code above was producing the “Missing argument” error.

When I changed the code above to

<div class="sidebar">
<?php if ( is_404() || is_category() || in_category(7) || is_single() || is_day() || is_month() || is_year() || is_search() || is_paged() || is_page() ) { ?>

everything started working correctly (with no errors!).

I assume one would have to add an “in_category” instance for each category that requires a specific conditional tag later in the sidebar’s code.

For example,

<div class="sidebar">
<?php if ( is_404() || is_category() || in_category(7) || in_category(8) || in_category(9) || is_single() || is_day() || is_month() || is_year() || is_search() || is_paged() || is_page() ) { ?>

(where category ID numbers 7,8 & 9 will have specific conditional tags within the sidebar)

I hope this helps.

Thank you Kafkaesqui! Thank you for the original code & for your helping me implement it properly!

I had reviewed the get_posts page before and (believe) I have the method for displaying the post data. My question was more about the accuracy of calling the code from within a conditional tag.

Perhaps it would have been clearer, had I included more of the code which I’ve tried to employ…

(I apologize for the mess of this following code; I’m just learning & trying my darndest to make something nice & efficient)

<?php if ( is_category() ) {
if (is_category('3')) {
// Special Code Here for Category 3
...
...
} else {
// catch-all for other categories
echo "<li><h2>Section Title</h2>";
echo "<ul>";
echo "$photog_posts = get_posts('category=2&numberposts=10');";
echo "foreach($photog_posts as $post) : setup_postdata($post);";
echo "<li>";
echo "<a href=\"";
echo the_permalink();
echo "\" rel=\"bookmark\" title=\"Permalink to";
echo the_title();
echo "\">";
echo the_title();
echo "</a></li></ul>";
echo "</li>";
}
}
?>

This whole use of the foreach() within the Conditional Tags is what is causing me such trouble.

At least, that’s what I think my problem is; unless I’m completely misunderstanding something.

(thanks again for any & all help!)

OK, I may have found the solution (I’m not 100% on this, so verification from someone else would be greatly appreciated!) and am posting it here so that others searching for the same problem might find my solution helpful.

1. Visit http://tinymce.moxiecode.com/tinymce/docs/reference_buttons.html to find the name of the button you are interested in added. In my case, I wanted to add a method for applying a format to a paragraph (h1, h2, etc.) this is called “formatselect.”
2. Open the file “tiny_mce_gzip.php” in the “tinymce” folder within the “js” folder that’s within the “wp-includes” folder. So, it’s wp-includes>js>tinymce>tiny_mce_gzip.php
3. Find the code that reads:
   $mce_buttons = apply_filters('mce_buttons', array('bold', 'italic', 'strikethrough', 'separator', 'bullist', 'numlist', 'outdent', 'indent', 'separator', 'justifyleft', 'justifycenter', 'justifyright' ,'separator', 'link', 'unlink', 'image', 'wordpress', 'separator', 'undo', 'redo', 'code', 'wphelp'));
4. Add the button name that you wish to have show up in the button array. In my case, I wanted “formatselect” so I modified the code to display as:
   $mce_buttons = apply_filters('mce_buttons', array('bold', 'italic', 'strikethrough', 'separator', 'formatselect', 'separator', 'bullist', 'numlist', 'outdent', 'indent', 'separator', 'justifyleft', 'justifycenter', 'justifyright' ,'separator', 'link', 'unlink', 'image', 'wordpress', 'separator', 'undo', 'redo', 'code', 'wphelp')); (adding both “formatselect” and a separator)

That’s it!

Anyone able to help with this? …please… 🙂
