Show post numbers

Hi,

I want to show the current post number on the total post.

For exemple, in category “Z” I have 5 posts. I would like to show something like this : Post 1 of 5 in category Z

Firstly, I used this function to get the total posts of my Z category:

[Code moderated as per the Forum Rules. Please use the pastebin]

And on my file, I placed this line of code : wt_get_category_count();

After, I needed to count the current post… I used this little function to achived it :

[Code moderated as per the Forum Rules. Please use the pastebin]

With this function, I placed this part of code to render the “Page x of” :

<?php $currentID = get_the_ID(); ?>
<?php $currentNumber = Get_Post_Number($currentID); ?>
<?php echo 'Page '.$currentNumber.' of'; ?>

At this point, evertything works pretty fine execpt one thing… If I’m on the first post, I get this Page 1 of X (correct)… But, if I’m on the last post count, I’m getting something like Page 0 of X like if in the function, the last post get a replace for the value of 0.

Can some 1 tell me how I could replace the “0” by the last number?

Here is what it looks like :

<span class="post_info">Page <?php echo $currentNumber.' of '.wt_get_category_count(); ?></span>
Page 1 of 5
Page 2 of 5
Page 3 of 5
Page 4 of 5
Page 0 of 5
