How do i control a "foreach" loop when it is inside a "while" loop? (uses smarty)

31 New Member
So I am trying to display a title, date, and content of a wordpress blog. Word press provides nice drop in functions to get the job done with simple names like "the_title" , and the "the_conten t" But on the homepage of a site, i wanted to truncate the content to like the first 75 characters and then put "..." (a perfect use of the smarty "truncate" modifier) and then give the visitor a link to read the whole article. But since "the_conten t" is a function, i can't really control the output without going in and tweeking the function. So i said, Ill just query the post db on my own, load the first 5 results in an array variable, and loop through them in the presentation, no sweat... here's what i got:

[PHP]
<ul>
//Wordpress (WP) checking for posts, then starts a "while" loop
{php}if ( have_posts() ) : while ( have_posts() ) : the_post(); {/php}

<!-- If the post is in the category we want to exclude, we simply pass to the next post. -->

//Tell WP to do the first 5 posts
{php} if (in_category('5 ')) continue; {/php}

<div class="post">

//Display the link for the full blog post, using the title of the post as the name
<li><h2><a href="{php} the_permalink() ; {/php}">{php} the_title();{/php}</a></h2></li>

//Display the date posted
<small>{php} the_time('F jS, Y'); {/php}</small><br />

//now HERE is where i dropped in my foreach loop to pull out the first 5
//contents and truncate them and add the "..."
{foreach from=$users item="query"}
{$query->post_content|t runcate:75:"... ":false}
{/foreach}

//Made another "Read All" link at the add of content summary
<a href="{php} the_permalink() ; {/php}">Read All</a>
<hr />


</div> <!-- closes the first div box -->
{php} endwhile; else: {/php}
<p>Sorry, no posts matched your criteria.</p>
{php} endif; {/php}
[/PHP]


I thought this would be gravy, and at first glance it looked like it worked. Until i took a closer look and saw what happened. WP code works fine, it's provided in their documentation. But my foreach loop cycles through the first five contents every time WP's while loop displays a post. I wanted it to do the first content in the first post, second content in the second post, and so on. To illustrate.

(example)
WP function got this (A,B,C,D,E)
My query got these results array(1,2,3,4,5 )

Now i want this to be displayed...

A1B2C3D4E5

But this is what I get...
A12345B12345C12 345D12345E12345

I understand why this is happening: everytime the WP while loop gets to my query, my smarty code is saying to loop through all my results. So how do i get my foreach loop to output the first index and wait til the next time it's called. My only other way I can think of is making a counter ($i) and actually typing in something like: $array[$i], and at the end of the while loop adding: $i++; but that makes it seem like im missing a bigger picture.

Let me know
Thanks

Hello, I'm writing an automatic SQL parser and translator from Informix to DB2. Now I'm faced with one of the most difficult things to translate, the "foreach execute procedure" functionality provided by Informix. This is the problem: the execution of the translated SQL leaves the rows in the temp table correctly but raises error SQL0480N. It's very simple to try it: ------------
