Getting WP excerpt in a category.php outside of WP loop

Question

I need some help pulling post excerpt out of the loop. I have few 'li's and need to display excerpt while hovering them. If it was inside the loop it would no problem, but haw can I force WP to display an excerpt form a post's link currently hovered?

<ul>
WP loop BLAH BLAH
<li>(number of <li>s depending of number of posts in current category)</li>
end of loop
</ul>
<div>show excerpt from currently hovered li</div>

thanks in advance!

PS: I tried with get_the_excerpt function, but it displays only last post's excerpt..

Answer 1

When you are in the wp loop, the current post counter is incremented in every iteration. and the get_the_exceprt function will display the excerpt of the current post.

so when the loop is over and you get out of it, and you call the get_the_excerpt function, it will display the 'last post's excerpt as for it it's the current item.

solution:

you need to reset the loop using rewind_posts() function before calling the get_the_excerpt function in new loop.

 while ( have_posts() ) : the_post();
//....loop.
endwhile;

rewind_posts();

//start a new loop.
 while ( have_posts() ) : the_post();
$excerpt=get_the_excerpt();

endwhile;

or while you are in the first loop, store the excerpts in an array, and use after you get out of the loop.
