I have created custom meta box using WPAlchemy class to add option for related posts.
Following code is working file in WP-Admin, and also in frontend only if i add related posts to the custom form created with meta box.
However if i leave this empty, i am getting following warning message
Warning: Illegal string offset 'topics' in
/homepages/9/d416241127/htdocs/tw/u2me/wp-content/themes/u2me/single.php
on line 37
Here line 37 is if ($my_meta['topics']) {
in other words i am getting warning message when this condition should return false.
I have used following code to create custom meta:
<?php while($mb->have_fields_and_multi('topics')): ?>
<?php $mb->the_group_open(); ?>
<?php $mb->the_field('title'); ?>
<label>Title</label>
<p style="margin-top:0px;"><input type="text" name="<?php $mb->the_name(); ?>" value="<?php $mb->the_value(); ?>"/></p>
<?php $mb->the_field('link'); ?>
<label>URL</label>
<p style="margin-top:0px;"><input type="text" name="<?php $mb->the_name(); ?>" value="<?php $mb->the_value(); ?>"/></p>
<p>Remove Topic</p>
<br/>
<?php $mb->the_group_close(); ?>
<?php endwhile; ?>
and used following code in single.php to show the values stored using above code:
<?php
$my_meta = get_post_meta($post->ID,'_related_topics_meta',TRUE);
if ($my_meta['topics']) {
echo '<ul class="hero-subtitle">';
foreach ($my_meta['topics'] as $topic) {
?>
<li><?php echo $topic['title']; ?></li>
<?php }
echo '</ul>';
} ?>
use
if ($my_meta['topics']) {
AS
if (!empty($my_meta['topics'])) {

How I search my WordPress site pages with search box I placed in my site?
Currently I am using this code.
<form id="searchform" method="get" action="<?php bloginfo('siteurl')?>/" style="margin-left: -43px;">
<input type="text" name="" id="s" class="textbox" placeholder="Search" required/>
<input id="btnSearch" type="submit" name="submit" value="<?php _e('Search'); ?>" />
</form>
I used name="s" but it not do search properly. I want that if user right page1 name search box take it to siteurl/page1 and so for page2 and remaining page.
Thanks in advance
Try this :
function redirect_search() {
if (is_search() && !empty($_GET['s'])) {
wp_redirect(home_url("/").urlencode($_GET['s']));
exit();
}
}
add_action('template_redirect', 'redirect_search' );
Add above code in your functions.php file.
So now when you type something, it will redirect it to that page.
NOTE:If you type something related to the published post, it will redirect to that POST instead of what have you entered.
For example : If I type hello in search box, then it will redirect you to hello world(which is default post that comes during installation of wordpress).
This is what have for you.
<div id="content" class="textbox <?php echo of_get_option('blog_sidebar_pos') ?>">
<?php _e('Search for:',''); ?> "<?php the_search_query(); ?>"
<?php
if (have_posts()) : while (have_posts()) : the_post();
$format = get_post_format();
get_template_part( 'include/'.$format );
if($format == '')
get_template_part( 'include/standard' );
endwhile; else:
?>
<?php echo '<p><strong>' . __('There has been an error.', '') . '</strong></p>'; ?>
<p> <?php _e('return to home page', ''); ?> <?php _e('use the search .', ''); ?></p>
<?php get_search_form(); ?>
</div><!--no-results-->
<?php endif; ?>
<?php get_template_part('include/post'); ?>
I have a Custom Post Type set up called Venues. I'm also using a plugin called Event Organiser, and I want to display the title and link to the venue within one of the Event Organiser templates.
The code is:
<?php if( $eo_event_loop->have_posts() ): ?>
<ul <?php echo $id; ?> class="<?php echo esc_attr($classes);?>" >
<?php while( $eo_event_loop->have_posts() ): $eo_event_loop->the_post(); ?>
<?php
//Generate HTML classes for this event
$eo_event_classes = eo_get_event_classes();
//For non-all-day events, include time format
$format = ( eo_is_all_day() ? $date_format : $date_format.' '.$time_format );
?>
<li class="<?php echo esc_attr(implode(' ',$eo_event_classes)); ?>" >
<a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>" ><?php the_title(); ?></a> at VENUE NAME HERE <?php echo __('on','eventorganiser') . ' '.eo_get_the_start($format); ?>
</li>
<?php endwhile; ?>
</ul>
Where VENUE NAME HERE is, I want the title and link to my custom post type. Might be just something really simple I'm missing, but any help much appreciated.
I used Advanced Custom Fields plugin and used 'Relationship' field so that I could choose a Venue for each event. Then used this code to bring through the Venue link:
<?php $venue = get_field('location_venue'); ?>
<?php foreach( $venue as $venue ): ?>
<?php echo get_the_title( $venue->ID ); ?>
<?php endforeach; ?>

I am using an if elseif statement to check what page it is, and it requires that there are posts on the page so when a search is returned with a result of 0, my code stops working. Any ideas how to code this better?
this code is in my sidebar and is showing the recent articles, you can see an example of a search working here(the sidebar is setup as a sub-footer):
http://ivry.sweetyams.ca/?s=new
and a search not working here:
http://ivry.sweetyams.ca/?s=asjdfkl%3B
Code I am using:
(I have tried putting stuff into the else{ code and it doesn't work either because there are no posts on the 'nothing found' search page
<?php if (have_posts()) : ?>
<?php /* IF SEARCH PAGE */ if (is_search() ) { ?>
<?php query_posts('category_name=0&showposts=5'); ?>
<?php while (have_posts()) : the_post(); ?>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
<p> <?php the_title(); ?></p>
</a>
<?php endwhile;?>
<?php /* IF ESCALADE PAGE */ }elseif (is_category_or_sub(6)) { ?>
<?php query_posts('category_name=escalade&showposts=5'); ?>
<?php while (have_posts()) : the_post(); ?>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
<p> <?php the_title(); ?></p>
</a>
<?php endwhile;?>
<?php /* IF MONTAGNE PAGE */ } elseif (is_category_or_sub(14)) { ?>
<?php query_posts('category_name=montagne&showposts=5'); ?>
<?php while (have_posts()) : the_post(); ?>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
<p> <?php the_title(); ?></p>
</a>
<?php endwhile;?>
<?php } else { ?>
DO SOMETHING ELSE
<?php }?>
<?php endif; ?>`
I am trying to get all recent articles for my sidebar and when there is no result in the search, it also stops my sidebar from working.
The code I added is not in my search page but in my SIDEBAR, it separates the comments into 2 categories, (6 and 14) I am essentially splitting my site using categories for navigation, anything as a child below 6 will be styled one way and 14 the other, you can see the difference on the escalade and montagne links:
This is getting every post below escalade, OR every post below the montagne category
My search pulls results from ALL categories, but if there is no search result, for some reason my sidebar code, the code I included, doesn't work.
first, showposts is deprecited since v2.1, used posts_per_page instead.
second, after each query_post, you need to reset the query like this:
<?php
// The Query
query_posts( $args );
// The Loop
while ( have_posts() ) : the_post();
echo '<li>';
the_title();
echo '</li>';
endwhile;
// Reset Query
wp_reset_query();
?>
this is how I understand it. see more detail here:query_posts(), hope this helps.
I found a way to get it to work,
I found that it is encouraged to use WP_Query for secondary posts within a page, http://new2wp.com/noob/query_posts-wp_query-differences/
also, for anyone that is wondering the is_category_or_sub function is from here: http://valendesigns.com/wordpress/is-category-or-subcategory-wp-function/
This code checks whether you are on a category or subcategory,
<?php
$my_posts = new WP_Query(); ?>
<?php /* IF ESCALADE PAGE */ if (is_category_or_sub(6)) { ?>
<?php $my_posts->query('posts_per_page=5&cat=6');?>
<?php /* ELSEIF MONTAGNE PAGE */ } elseif (is_category_or_sub(14)) { ?>
<?php $my_posts->query('posts_per_page=5&cat=14'); ?>
<?php } /* AND OTHER PAGE */ else { ?>
<?php $my_posts->query('posts_per_page=5'); ?>
<?php }?>
<?php while ($my_posts->have_posts()) : $my_posts->the_post(); // loop for posts ?>
<a href="<?php echo esc_url( get_permalink( $post->the_permalink ) ) ?>" title="Permanent Link to <?php echo substr($post->post_title,0,200);?>">
<p><?php echo substr($post->post_title,0,200); ?></p>
</a>
<?php endwhile; ?>
<?php wp_reset_query() // RESET QUERY ?>
I need to display link after each comment, when you click that link, a new page displays that single coment on a new page.
Is that possible?
I answered your exact question over on WordPress Answers (also a StackExchange site) just yesterday. You can find that answer here. It involved the following four steps:
Setting up the URL Rewriting by adding a query_var, rewrite_tag and a permastruct,
Being sure to flush the rewrite rules in a plugin's activation hook or manually,
Adding a parse_query filter hook to set the query_vars's post to be the comment's post and to disable sticky posts for the query,
Adding a template_include filter hook to filter the template file name to load a template specific template file for a single comment, and lastly
To create the comment template file as /wp-content/themes/%your-theme%/comment.php.
Again, you can find the answer over here.
Hope this helps.
-Mike
UPDATE:
Below is the full content that I had also posted on WordPress Answers:
There are numerous different ways to accomplish this, some more polished than others and practically all of them with potential for conflict with other plugins, but ignoring all that here's one way that is pretty close to what you asked for. :)
This solution will support a URL format like the following where %comment_id% is the numeric ID of your comment from the wp_comments table:
http://example.com/comments/%comment_id%/
First you'll need to configure your URL rewriting using the following code. Hopefully it is reasonably self-explanitory but don't hesitate to ask:
$wp->add_query_var('comment_id'); // Add the "behind-the-scenes" query variable that WordPress will use
$wp_rewrite->add_rewrite_tag('%comment_id%', '([0-9]+)','comment_id='); // Define a rewrite tag to match that assigns to the query var
$wp_rewrite->add_permastruct('comment-page', 'comments/%comment_id%'); // Define a URL pattern to match the rewrite tag.
You'll also either need to call this code in a plugin activation hook to flush the rules, or if it's your site you can just save permalinks in the admin console's Settings > Permalinks settings area:
global $wp_rewrite;
$wp_rewrite->flush_rules(false);
Next add a parse_query filter hook. This will be called after WordPress has inspected the query. It tests to see if your added comment_id query_var set and if so it tests to see if you are on the desired URL. If yes then it loads the comment array using get_comment() in order to set the 'p' parameter (which should be set to a post ID) to the post that is related to the comment. That way when WordPress runs the query that it is going to run no matter what at least it loads something you'll need in your comment.php theme template file below and you won't have to ran another query later when you need it. This code also tells WordPress to ignore sticky posts using the oddly named caller_get_posts option:
add_filter( 'parse_query', 'my_parse_query' );
function my_parse_query( $query ) {
global $wp;
if (isset($query->query['comment_id']) && substr($wp->request,0,9)=='comments/') {
$comment = get_comment($query->query['comment_id']);
$query->query_vars['p'] = $comment->comment_post_ID; // Causes the comment's post to be loaded by the query.
$query->query_vars['caller_get_posts'] = true; // Keeps sticky posts from invading into the top of our query.
}
}
Still next you'll need to hook the code in /wp-includes/template-loader.php using the template_include filter. This will be called after WordPress has both inspected the query and loaded the post for the comment. Here you'll first check again for comment_id in the query_var and also for the URL being the one you want. If so we replace the /index.php template page with /comment.php which is a theme template file you will need to create:
add_filter( 'template_include', 'my_template_include' );
function my_template_include( $template ) {
global $wp,$wp_query;
if (isset($wp_query->query['comment_id']) && substr($wp->request,0,9)=='comments/') {
$template = str_replace('/index.php','/comment.php',$template);
}
return $template;
}
Lastly now you need to create your theme template file which I've chosen to call /comment.php. Since it's your theme you'll want to make it look like you want but here is an example to get you started:
<?php
/*
* File: /wp-content/themes/my-theme/comment.php
*/
global $wp_query,$post;
$comment_id = $wp_query->query['comment_id'];
$comment = get_comment($comment_id);
$permalink = get_permalink($post->ID);
get_header();
?>
<div id="container">
<div id="comment-<?php echo $comment_id; ?>" class="comment">
<p>Comment by: <span class="comment-author">
<?php echo $comment->comment_author; ?></span>
on <span class="comment-date"><?php echo date("D M jS Y", strtotime($comment->comment_date)); ?></span>
at <span class="comment-time"><?php echo date("h:ia", strtotime($comment->comment_date)); ?></span>
</p>
<p>About: <?php echo $post->post_title; ?></p>
<blockquote><?php echo $comment->comment_content; ?></blockquote>
</div>
</div>
<?php
get_sidebar();
get_footer();
Any questions? Just ask.
Hope this helps.
P.S. All of the code I describing above can either go in your theme's functions.php file and/or in a plugin of your own. A caveat is for the URL rewrite flushing rules that should go in a plugin activation hook if you are going to include it instead us just flushing them manually in the permalinks section of the admin console. I didn't show how to register an activation hook do but if you want to learn more you can read about it here.
(New edited version after OP's comments)
There are many ways to do this. In theory this is the simplest, but maybe not 'most appropriate according to WordPress' way. Take this as a starting point. I haven't tested it, so you may encounter an error or two that should be solvable with some minor tweaks. Let me know if you get stumped and I'll do my best. So conceptually...
You should copy the page.php template file and rename it to 'comments_page.php' (or whatever you like). Open this file in your code editor and find where the following appears: (or create it if it does not exist)
/*Template Name: page*/
and change it to
/*Template Name: comments_page*/
Now open your WordPress admin area and create a new page. Call it whatever you want but don't add any content. In the right hand column, select the template that the page uses from the "Page Template" drop down menu. Select 'comments_page' (or whatever you listed as the template name). This tells WordPress to use your file to show this specific page instead of the default page template. Save the page and note the page_id that WordPress generates.
Now, find your theme's comments template, usually 'comments.php'. Find the function wp_list_comments();. We are going to add the name of a custom function that will control the display of your comments as an argument to this function. For an example, go to the twenty-ten theme's files, open comments.php and you'll see what that looks like:
wp_list_comments( array( 'callback' => 'twentyten_comment' ) );
Open the twenty-ten theme's functions.php and find
function twentyten_comment()
Copy that entire function and paste it into your theme's functions file. Change the name to' my_comment()', and add that to the wp_list_comments function call like this:
wp_list_comments( array('callback'=>'my_comment'));
In your newly-created 'my_comment()' function in your functions.php file, add a link where you want to the separate page of comments (comments_page.php) using get_page_link() and a query var named 'commentID' and the comments ID.
View this comment
Now to inappropriately add php logic to a template file. Once you understand how this works, you can create a function in your functions.php file and then call it in the theme file...
On comments_page.php ,use $_GET['commentID'] to retrieve the comment's id value from the url, and pass it to get_comment($commentID) to retrieve the single comment and display it on a single page.
if(isset($_GET['commentID'])){$commentID = $_GET['commentID'];}
$comment = get_comment($commentID);
Now you have all the single comments information in the $comment variable as an object.
You can decide how to display the comment, but to start, I recommend copying the contents of your theme's comments template to keep things consistent. It will show exactly the same thing the post page shows, but it sounds like this page is intended more for the permalink to a single comment that you link to from somewhere else.
Hope this helps. Let me know if you run into a snag.
Note: this answer provides info given to me from Todd Perkins over at wordpress.stackexchange.com
This is my functions.php

First I've created a home.php page to replace index.php and can add some custom fields on this new one and to have in it lastest 3 posts.
On home.php page I put:
<?php echo get_post_meta($post->ID, 'test', true); ?>"/>
but it doesn't works cause it tries get the post id and not the id of the page. If i put 18 (id of the page) directly it works, but i want it dinamicaly:
<?php echo get_post_meta(18, 'test', true); ?>"/>
And this condition is not satisfied for test:
if($post->post_type == 'page'){
echo 'This item is a page and the ID is: '.$post->ID;
}
Heyo,
I think your problem might be that you should have that within a loop.
For example if you were displaying several post from a category and displaying each custom field it might look like this:
<?php query_posts('cat=25&showposts=3'); ?>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<li class="homeblock" style="max-width:400px;">
<span class="artist-name">
<?php $key='artist'; echo get_post_meta($post->ID, $key, true); ?>
</span>
<div class="entry-thumbnail">
<?php the_post_thumbnail(); ?>
</div>
</li>
<?php endwhile; endif; ?>
Otherwise (not sure how your theme is set up), what you might have to do is edit content.php and add:
<?php $key='artist'; echo get_post_meta($post->ID, $key, true); ?>
Try:
if ($post->post_type == 'page') {
<?php echo get_post_meta($page_id, 'test', true); ?>
}
Hope this helps :)
