Hi,
Would any be able to help me out on this query....
I'm trying to add a different style class to every 3rd post displayed inside the loop.
I'd also like to use this to add a </tr><tr> after every 3rd post on another page (so I can list lots of posts to a table with 3 on each row).
Thanks for any help on this one!
I'd say there may be a lot of ways to do that..
Put a counter into loop and fetch style information from a "style pool" using that counter; be sure to use "cycling fetching"...
Let's say:
$style_classes = array('first','second','third');
$style_index = 0;
// ...
// in a loop:
<span class="<?php echo "class=$style_classes[$style_index%3]"; $style_index++; ?>"> .... </span>Does this make sense?

Hi Dor,
I can't get this to work. Below is the code I have...
<?php
query_posts("cat=5&showposts=3&offset=0");
while (have_posts()) : the_post();
$style_classes = array('first','second','third');
$style_index = 0;
?>
<div class="<?php echo "class=$style_classes[$style_index3]"; $style_index++; ?>">
<div class="indexreview"><a href="<?php the_permalink() ?>" title="read the interview with <?php the_title_attribute(); ?>"><?php echo c2c_get_custom('Image URL', '<img src="', '" width="240" height="88" '); ?>alt="<?php the_title_attribute(); ?>" />
</a>
</div>
<h3 class="interviewheader"><a href="<?php the_permalink() ?>" title="read the interview with <?php the_title_attribute(); ?>"><?php the_title(); ?></a>
</h3>
<?php echo c2c_get_custom('Stand First', '<p>', '</p>'); ?>
<div class="postdate"><?php the_time('d.m.y') ?> </div>
<div class="commentquote"><?php comments_popup_link('0', '1', '%'); ?></div>
</p>
</div>
<?php endwhile; ?>
</div>I get the following error:
Parse error: syntax error, unexpected '%', expecting ']' in [mydomain] on line 139
Can you shed any light on what I'm doing wrong?
First, this:
$style_classes = array('first','second','third');
$style_index = 0;should be outside of the loop. Before query_posts, let's say.
Next, right you are, that's my fault, try to use one more variable, like this:
<div class="<?php $k = $style_index%3; echo "class=$style_classes[$k]"; $style_index++; ?>">Mmm... should work.

Thanks! If you want more or less options do you just change the number of classes in that array and the number here $style_index%3;?
I'm not using code like this,
but you can try:
// outside the loop:
$style_classes = array('first','second','third', 'fourth');
$styles_count = count($style_classes);
$style_index = 0;
// inside the loop:
<div class="<?php $k = $style_index % $styles_count; echo "class=$style_classes[$k]"; $style_index++; ?>">So, you can change "styles pool" (or, in general case, variables "pool") and loop fetching over $styles_count.
Well, you can use also a variant with no extra variable (my fault again):
// inside the loop:
<div class="<?php echo $style_classes[$style_index++ % $styles_count]; ?>">

This is awesome, but I'm not sure how to implement a similar option using the wp_nav_menu tag. I'm not very familiar with PHP.
This is what I have. I get a parse error if I use another <?php ?> inside for the class of the span. Any ideas on how to make it work for this template tag?
<?php
$style_classes = array('first','second','third','fourth');
$style_index = 0;
?>
<?php wp_nav_menu( array( 'container_class' => 'menu-header', 'before' => '<span class="$k = $style_index%3; echo "class=$style_classes[$k]"; $style_index++;">', 'after' => '</span>' ) ); ?>This topic has been closed to new replies.
