Putting php code inside php code

What kind of errors are you getting? I suspect it has to do with the <?php if(have_posts()) : while(have_posts()) : the_post('exclude=3'); ?> and the endwhile, else: and endif; that happens later in the code.

Parse error: syntax error, unexpected ‘<‘

I think im doing a newbie mistake…This is how I put the code inside:

<? if (is_single('2466')){
   query_posts($query_string . '&cat=72');

<div id="twitter">
<h2>Latest Articles</h2>
<ul id="twitter_update_list"></ul>
<br/>

<?php if(have_posts()) : while(have_posts()) : the_post('exclude=3'); ?>

	<div class="entry2">
	<div class="post" id="post-<?php the_ID(); ?>">

	<b><a href="<?php the_permalink() ?>" rel="bookmark" title="Read the rest of <?php the_title_attribute(); ?>"><?php the_title(); ?></a>
	</b>
	<span class="content">
	<?php the_excerpt(); ?>
	</span>
	<div class="clearfloat"></div>
<?php edit_post_link('edit', '', ''); ?>
	<div class="allinfos">

	</div>

	</div>
	</div>
	<?php endwhile; ?>

	<div style="padding:10px;"><!-- page navi -->
	<?php if(function_exists('wp_page_numbers')) { wp_page_numbers(); } ?>
	<!-- page navi end --></div>

	<?php else : ?>

	<h2 class="center">Not Found</h2>
	<p class="center">Sorry, but you are looking for something that isn't here.</p>
	<?php include (TEMPLATEPATH . "/searchform.php"); ?>

<?php endif; ?>

</div>

}

Try this

<?php
 global $query_string;
if (is_single('2466')){
   query_posts($query_string . '&cat=72&category__not_in=3');
   if(have_posts()) : while(have_posts()) : the_post(); ?>

	<div class="entry2">
	<div class="post" id="post-<?php the_ID(); ?>">

	<b><a href="<?php the_permalink() ?>" rel="bookmark" title="Read the rest of <?php the_title_attribute(); ?>"><?php the_title(); ?></a>
	</b>
	<span class="content">
	<?php the_excerpt(); ?>
	</span>
	<div class="clearfloat"></div>
<?php edit_post_link('edit', '', ''); ?>
	<div class="allinfos">

	</div>

	</div>
	</div>
	<?php endwhile; ?>

	<div style="padding:10px;"><!-- page navi -->
	<?php if(function_exists('wp_page_numbers')) { wp_page_numbers(); } ?>
	<!-- page navi end --></div>

	<?php else : ?>

	<h2 class="center">Not Found</h2>
	<p class="center">Sorry, but you are looking for something that isn't here.</p>
	<?php include (TEMPLATEPATH . "/searchform.php"); ?>

<?php endif; } ?>

</div>

Try this

<?php
 global $query_string;
if (is_single('2466')){
   query_posts($query_string . '&cat=72&category__not_in=3');
   if(have_posts()) : while(have_posts()) : the_post(); ?>

	<div class="entry2">
	<div class="post" id="post-<?php the_ID(); ?>">

	<b><a href="<?php the_permalink() ?>" rel="bookmark" title="Read the rest of <?php the_title_attribute(); ?>"><?php the_title(); ?></a>
	</b>
	<span class="content">
	<?php the_excerpt(); ?>
	</span>
	<div class="clearfloat"></div>
<?php edit_post_link('edit', '', ''); ?>
	<div class="allinfos">

	</div>

	</div>
	</div>
	<?php endwhile; ?>

	<div style="padding:10px;"><!-- page navi -->
	<?php if(function_exists('wp_page_numbers')) { wp_page_numbers(); } ?>
	<!-- page navi end --></div>

	<?php else : ?>

	<h2 class="center">Not Found</h2>
	<p class="center">Sorry, but you are looking for something that isn't here.</p>
	<?php include (TEMPLATEPATH . "/searchform.php"); ?>

<?php endif; } ?>

</div>

thx but i recieve:

Warning: implode() [function.implode]: Invalid arguments passed in /var/customers/webs/side/wp-includes/query.php  on line 1907

<?php

	<?php include (TEMPLATEPATH . "/searchform.php"); ?>

<?php endif; } ?>

</div>

I replace something. Try this code now.

IF solve, mark it as resolved.

thx, actually the one before ur last post worked but only if u remove the global $query_string;

I dont know why, but if u remove it no more errors.. kinda wierd

Another enhanced question to my problem.

My code shows the latest posts of category X in my sidebar.
Now I wanted to add a second box showing category Y posts under it.

So i put it in between my (is_single('2466')){ code.

Original code:

<?php
if (is_single('2466')){
   query_posts($query_string . '&cat=1&category__not_in=3');
   if(have_posts()) : while(have_posts()) : the_post(); ?>
<br><div id="twitter">
<h2>Latest Articles</h2>
<ul id="twitter_update_list"></ul>
<br/>

	<div class="entry2">
	<div class="post" id="post-<?php the_ID(); ?>">

	<b><a href="<?php the_permalink() ?>" rel="bookmark" title="Read the rest of <?php the_title_attribute(); ?>"><?php the_title(); ?></a>
	</b>
	<span class="content">
	<?php the_excerpt(); ?>
	</span>
	<div class="clearfloat"></div>
<?php edit_post_link('edit', '', ''); ?>
	<div class="allinfos">

	</div>

	</div>
	</div>
	<?php endwhile; ?>

	<div style="padding:10px;"><!-- page navi -->
	<?php if(function_exists('wp_page_numbers')) { wp_page_numbers(); } ?>
	<!-- page navi end --></div>

	<?php else : ?>

	<h2 class="center">Not Found</h2>
	<p class="center">Sorry, but you are looking for something that isn't here.</p>
	<?php include (TEMPLATEPATH . "/searchform.php"); ?>
</div>
<?php endif; } ?>

——————————–
Now I add the second box and recieve this error Parse error: syntax error, unexpected T_ENDWHILE in /var/customer/webs/side/wp-content/themes/Dig/sidebar.php on line 63

Here is how I did it:
