Filtering Search Results with Wordpress - php

I'm trying to setup a Search Results page with two columns. First column will present results from all categories except one ( Galleries ), and the second column will present only the Galleries category.
query_posts() simply resets my results. This is what I got so far. Broken:
<?php
$s = get_query_var('s');
query_posts('s=' . $s . '&cat=164');
?>
<?php
// First Loop
?>
<div class="contentLeft">
<ul class="postListSmall related">
<?php while (have_posts()) : the_post(); ?>
[do stuff]
<?php endwhile; ?>
<?php
// Second Loop
?>
<?php query_posts('cat=-164'); ?>
<?php rewind_posts(); ?>
<?php while (have_posts()) : the_post(); ?>
[do stuff]
<?php endwhile; ?>
<?php else : ?>
[do stuff]
<?php endif; ?>
What to do?

I know this is an old post but I am having a similar problem and thought I would share:
You are creating a query, then calling a second query, but then trying to rewind the query. That's not how the rewind function works. Take a look at the Rewind Documentation. You also say:
query_posts() simply resets my results.
Then why are you calling the rewind function immediately after the new query? Also, if you're resetting the results then why is it a different query completely? This:
$s = get_query_var('s');
query_posts('s=' . $s . '&cat=164');
Is not the same as this:
<?php query_posts('cat=-164'); ?>
<?php rewind_posts(); ?>
To get 2 column results for different categories I did the following: use only one loop, don't use rewind, use get_the_category in an if statement in your loop, for example:
<?php
$s = get_query_var('s');
query_posts('s=' . $s . '&cat=164');
while (have_posts()) : the_post();
foreach(get_the_category() as $category){
if($category->name == "category name"){
//Concatenate to the left div
} else {
//concatenate to the right div
} ?>
Hope this helps.

Php continue not working if not empty?

I am having a loop and that loop has only sticky posts in it. So my logic works like this:
"If Sticky Posts are "EMPTY" break the loop". That code works as expected and looks like this:
<?php //we will get "Sticky Posts" only with this loop and exlude Featured Category
$category = get_cat_ID('Featured');
$col = 1; //Let's create first column
$sticky = get_option( 'sticky_posts' );
$args = array(
/* Add whatever you need here - see http://codex.wordpress.org/Class_Reference/WP_Query */
'paged' => $paged,
'category__not_in' => array($category),
'post__in' => $sticky,
'ignore_sticky_posts' => 1
);
$temp = $wp_query;
$wp_query = null;
$wp_query = new WP_Query($args);
/*Below is IMPORTANT PART*/
if($wp_query->have_posts()):?><?php while ( $wp_query->have_posts() ) :
$wp_query->the_post();if(empty($sticky))break;?>
<div <?php post_class('col'.$col); ?> id="post-<?php the_ID(); ?>">
<?php if ($col == 1) echo '<div class="row">';//If column 1 create first row ?>
<?php if ($col == 2) echo '<div class="row2">';//If column 2 create second row ?>
<h3 class="mytitle"><?php the_title(); ?></h3>
<div class="entry">
<?php if ( has_post_thumbnail() ):?>
<div class="featured_img">
<?php
the_post_thumbnail();
echo '<div class="featured_caption">' . get_post(get_post_thumbnail_id())->post_excerpt . '</div>';
?>
</div><!--/featured_img-->
<?php endif; ?>
<?php // let's enable more link on pages...
global $more;
$more = 0;
?>
<?php the_content(__('Read more','override')); ?>
<div class="clear"></div>
<div class="custom_fields"><?php the_meta(); ?></div><br/>
<p class="postmetadata">
<?php _e('Filed under:','override'); ?> <?php the_category(', ') ?> <?php _e('by','override'); ?> <?php the_author(); ?><br/><?php the_tags(__('Tags:','override'), ', ', '<br />'); ?>
<?php _e('Posted on: ','override'); ?><?php the_time(get_option('date_format')); ?><br/>
<?php if ( comments_open() ) {
comments_popup_link(__('No Comments »','override'), __('1 Comment »','override'), __('% Comments »','override'));}
else {
_e('Comments are disabled!','override');
}
?>
<?php edit_post_link(__(' Edit','override'), __(' |','override'), ''); ?>
</p>
</div><!--/entry-->
</div><!--/post_class-->
<?php /*Enable Two Column Layout*/
if($col==1) {
$col=2;
echo "</div>";
}
else if($col==2) {
$col=1;
echo "</div>";
}
endwhile; ?>
<?php endif; ?><!--END if THE LOOP (Sticky)-->
<?php
$wp_query = null;
$wp_query = $temp;
wp_reset_query();
?>
Now before this working code I tried a different logic that goes like this:
"If NOT EMPTY continue the loop" so now everything in my code stays the same except:if($wp_query->have_posts()):?><?php while ( $wp_query->have_posts() ) :
$wp_query->the_post();if(empty($sticky))break;?> so now that code becomes:if($wp_query->have_posts()):?><?php while ( $wp_query->have_posts() ) :
$wp_query->the_post();if(!empty($sticky))continue;?>
Now this is where i got confused because if(!empty($sticky))continue; part does not work as expected because my loop CONTINUES (returns other posts) even if there are no "Stickies". I thought that loop will STOP if there are no stickies but it is not the case. My var_dump($sticky)
shows this if there are sticky postsarray(1) { [0]=> int(214) } and shows this if there are no stickiesarray(0) { }.
My question is: Why the loop continues to return other posts if using if(!empty($sticky))continue; (i thought it will return ONLY "Stickies" if they exist and return NOTHING if they are not here. )
Thank you!!
First off, let me poit out that your logic doesn't quite agree with your code :).
From what I understand from your code, you want to iterate all posts WP_Query() returned, but only render sticky ones. Your if is inside the wile loop, so you have to check if the current post is sticky or not. However, if(empty($sticky)) doesn't do that. It checks if there are any sticky posts at all. A way to check the current post would be if(is_sticky(the_ID())).
Now, concerning continue:
From the php manual:
continue is used within looping structures to skip the rest of the
current loop iteration and continue execution at the condition
evaluation and then the beginning of the next iteration.
So as you can see, continue doesn't stop the loop, but rather attempts to start the next iteration ignoring the rest of the code for the current step. Which is what you want, if the current post is not sticky, in other words if(!is_sticky(the_ID())).
However, I think you don't really need any check at all, since you already specified that you want WP_Query() to fetch only stickies ('post__in' => $sticky).
See also: this WordPress Answers topic.
I don't know well the wordpress code, but in that code, the $sticky variable is never updated in the while loop. So maybe you have to add $sticky = get_option( 'sticky_posts' ); right before the if condition.

While cycle create an infinite loop

I wrote this PHP code to put on a wordpress page template:
<?php
query_posts('showposts=10&cat=7');
while (have_posts()) : the_post();
?>
<li class="img-slider">
<?php the_content(); ?>
</li>
<?php endwhile; ?>
When I view the page I don't see any result and the right bar of the browser continue to reduce itself. I have understand that the code create an infinite loop.
Where I mistake?
Thanks
Firstly, you should not use query_posts. It's too invasive for simple loops, and messes with the entire WP_Query. Also showposts should be posts_per_page.
Secondly, it's hard to gauge what this issue is without more context. Perhaps pastebin your entire page, and edit it into your question. My guess is a loop within a loop, and should stop at like a 100 posts. (10 X 10) but if it's reset anywhere else if could very well go infinite!
Use this code instead to create loops:
$custom_query = new WP_Query( 'posts_per_page=10' );
if($custom_query->have_posts()) :
while ( $custom_query->have_posts() ) : $custom_query->the_post();
//global $post; // for stuff like $post->post_name
// Post stuff here
// the_title();
endwhile;
endif;
// Reset Post Data
wp_reset_postdata();
Look at the WordPress codex for more details. http://codex.wordpress.org/Class_Reference/WP_Query#Parameters
You should use an if statement in your loop:
<?php
query_posts('showposts=10&cat=7');
if ( have_posts() ): while ( have_posts() ) : the_post();
?>
<li class="img-slider">
<?php the_content(); ?>
</li>
<?php endwhile; endif; ?>
Without further information, I would say that in each loop of the while statement, the function is returning the first row of the data? So each time the while loop executes you are calling the function again, which is returning the same row over and over again without actually iterating through the result set.

How do you stop echo of multiple values with 'foreach' in PHP?

How do you when using custom fields in Wordpress echo just the first value using foreach?
Currently the code is:
<?php for(get_field('venue_event') as $post_object): ?>
<?php echo get_the_title($post_object) ?>
<?php endforeach; ?>
This takes the field from the wordpress page (the field is a link to another page), creates a link to that page using get_permalink but when I want to echo the page title it does it, but then it also echos all other values that are not needed.
If you just want the execute the first iteration of the loop, try this:
<?php foreach(get_field('venue_event') as $post_object): ?>
<?php echo get_the_title($post_object) ?>
<?php break; ?>
<?php endforeach; ?>
Wouldn't it then be easier just to use the first element of the returned array? Maybe Wordpress offers other filters that return the the page's title only.
you can just add
$counter = 0;
<?php for(get_field('venue_event') as $post_object): ?>
$counter++;
if($counter == 1)
{
<?php echo get_the_title($post_object) ?>
}
<?php endforeach; ?>

How can I combine this php statement to get the results of multiple variable inputs?

This is my WordPress query but is not a wordpress related question. It shows the posts that have meta_key as extra1 and meta_value as test
<?php $customkey1 = extra1; ?>
<?php $customvalue1 = test; ?>
<?php query_posts('meta_key=' . $customkey1 . '&meta_value=' . $customvalue1 . ''); ?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<?php the_title(); ?>
<?php endwhile; ?>
<?php endif; ?>
My question is how can I still show the posts that have extra1 as metakey and test as metavalue but also the posts that have extra2 as metakey and test2 as metavalue in the same query. A combination of two or more variables.
So you want to combine the results of two queries? Check this out You may just need to make two query objects and combine them.
Something like (note, I do not have WordPress installed, nor use WordPress. But assuming that its API is not a lie):
<?php
// The Query
$the_query = new WP_Query( $args );
$the_second_query = new WP_Query( $args );
// The Loop
while ( $the_query->have_posts() ) : $the_query->the_post();
echo '<li>';
the_title();
echo '</li>';
endwhile;
// The Second Loop
while ( $the_second_query->have_posts() ) : $the_second_query->the_post();
echo '<li>';
the_title();
echo '</li>';
endwhile;
// Reset Post Data
wp_reset_postdata();
?>
Note: This is hideous, ugly, and will work but in most cases should be considered WRONG by professionals. More elegantly, at least I would use a function to parse the post. Most elegantly, I would do what has been suggested elsewhere, encapsulate the combined query in a MySQL bit. But given the op's knowledge, this seems to be the "best approach" for quickly solving this problem, hopefully only once. (Repeated application of this approach will turn it into a messy nightmare)

Picking the most recent post in WordPress with php

I am trying to do an if/else-statement on my WP-template. But i can't seem to pick the right element.
I wan't it to look for the latest post on the blog. I already added a script that add a class of .first to the latest post.
What im trying to do in dummy-php-language:
<?php
if ( class is .first) { do something to .first}
else () { do something to everything else }
?>
i've looked in the wp-documentation. But i can't seem to find anything that will select "latest post"...
Thanks
Jonas
A very simple solution would be to keep a count of the post you're at, and do something if it's the first. In the index.php, in the have_posts() loop:
<?php if (have_posts()) : $count = 0; ?>
<?php while (have_posts()) : the_post(); $count++; ?>
<?php if($count ==1) ?>
// do something to first
<?php else ?>
// do something to everything else
<?php endif; ?>
<?php endwhile; else: ?>
<?php endif; ?>
