I have a custom post type that has a bunch of posts all formatted like so
Artist - Song Title
for example
The Smashing Pumpkins - Quiet
I am trying to put 'Artist' in a variable $artist and 'Song Title' in a variable $song
$artistsong = get_the_title();
$songeach = explode("-", $artistsong);
$artist = $songeach[0];
$song = $songeach[1];
But this does not work. Echo-ing $artist gets the full title
The Smashing Pumpkins - Quiet
and echoing $song does not output anything
This works if I am just starting from plaintext, but not with 'get_the_title()'
$song = "The Smashing Pumpkins - Quiet";
$songeach = explode("-", $song);
$artist = trim($songeach[0]);
$song = trim($songeach[1]);
echo $artist;
//echos 'The Smashing Pumpkins'
echo $song;
//echos 'Quiet'
Is there another way to put the full title into a variable initially other than get_the_title() which does not seem to be working for me, or am I missing something else?
Add this code to your functions.php
function get_the_title_keep_hyphen( $post = 0 ) {
$post = get_post( $post );
$title = isset( $post->post_title ) ? $post->post_title : '';
$id = isset( $post->ID ) ? $post->ID : 0;
if ( ! is_admin() ) {
if ( ! empty( $post->post_password ) ) {
/**
* Filter the text prepended to the post title for protected posts.
*
* The filter is only applied on the front end.
*
* #since 2.8.0
*
* #param string $prepend Text displayed before the post title.
* Default 'Protected: %s'.
* #param WP_Post $post Current post object.
*/
$protected_title_format = apply_filters( 'protected_title_format', __( 'Protected: %s' ), $post );
$title = sprintf( $protected_title_format, $title );
} elseif ( isset( $post->post_status ) && 'private' == $post->post_status ) {
/**
* Filter the text prepended to the post title of private posts.
*
* The filter is only applied on the front end.
*
* #since 2.8.0
*
* #param string $prepend Text displayed before the post title.
* Default 'Private: %s'.
* #param WP_Post $post Current post object.
*/
$private_title_format = apply_filters( 'private_title_format', __( 'Private: %s' ), $post );
$title = sprintf( $private_title_format, $title );
}
}
/**
* Filter the post title.
*
* #since 0.71
*
* #param string $title The post title.
* #param int $id The post ID.
*/
return $title;
}
And use this code in your single.php
$artistsong = get_the_title_keep_hyphen();
$songeach = explode(" - ", $artistsong);
$artist = $songeach[0];
$song = $songeach[1];
See the last line
I change from return apply_filters( 'the_title', $title, $id ); to return $title;
Because apply_filters function change the hyphen from - => –.
It's because of the dash symbol.
Try $songeach = explode("P", $artistsong); and you'll see what I mean. You could try a different character between artist and song title - although probably not ideal.

I am trying to add some post titles from a custom post category. I currently have it printing the correct amount of <li> but unfortunately it is the same name. You will see I narrow it down using meta, so I am getting 5 results all the same name.
I do not pretend to be a pro at this, so I am humbly asking for any help that the community may have.
Thanks In advance.
I have tried doing a foreach and also doing the if have_posts. both have yielded the same result.
$page_title = get_the_title();
$args = array(
'orderby' => 'title',
'post_type' => 'person',
'post_status' => 'publish',
'meta_key' => 'division',
'meta_value' => 'Singles'
);
$string = '';
$query = new WP_Query( $args );
if( $query->have_posts() ):
$string .= '<ul>';
while( $query->have_posts() ):
$query->the_post();
$string .= '<li>' . get_the_title() . '</li>';
endwhile;
$string .= '</ul>';
echo $string;
wp_reset_postdata();
else :
// No, we don't have any posts, so maybe we display a nice message
echo "<p class='no-posts'>" . __( "Sorry, there are no posts at this time." ) . "</p>";
endif;
So what we are going for is looking for how many posts exist in "Singles" (in my case that is 5) and printing the post title for each one in an <li>. Currently it prints 1 of the 5, 5 times.
get_the_title() has the following implementation
function get_the_title( $post = 0 ) {
$post = get_post( $post );
$title = isset( $post->post_title ) ? $post->post_title : '';
$id = isset( $post->ID ) ? $post->ID : 0;
if ( ! is_admin() ) {
if ( ! empty( $post->post_password ) ) {
/**
* Filters the text prepended to the post title for protected posts.
*
* The filter is only applied on the front end.
*
* #since 2.8.0
*
* #param string $prepend Text displayed before the post title.
* Default 'Protected: %s'.
* #param WP_Post $post Current post object.
*/
$protected_title_format = apply_filters( 'protected_title_format', __( 'Protected: %s' ), $post );
$title = sprintf( $protected_title_format, $title );
} elseif ( isset( $post->post_status ) && 'private' == $post->post_status ) {
/**
* Filters the text prepended to the post title of private posts.
*
* The filter is only applied on the front end.
*
* #since 2.8.0
*
* #param string $prepend Text displayed before the post title.
* Default 'Private: %s'.
* #param WP_Post $post Current post object.
*/
$private_title_format = apply_filters( 'private_title_format', __( 'Private: %s' ), $post );
$title = sprintf( $private_title_format, $title );
}
}
/**
* Filters the post title.
*
* #since 0.71
*
* #param string $title The post title.
* #param int $id The post ID.
*/
return apply_filters( 'the_title', $title, $id );
}
As you can see you can pass a post to it and then it will get its title. Since you didn't pass a post to it, it didn't get a title for you. Suggestion:
$page_title = get_the_title();
$args = array(
'orderby' => 'title',
'post_type' => 'person',
'post_status' => 'publish',
'meta_key' => 'division',
'meta_value' => 'Singles'
);
$string = '';
$query = new WP_Query( $args );
if( $query->have_posts() ):
$string .= '<ul>';
while( $query->have_posts() ):
$string .= '<li>' . get_the_title($query->the_post()) . '</li>';
endwhile;
$string .= '</ul>';
echo $string;
wp_reset_postdata();
else :
// No, we don't have any posts, so maybe we display a nice message
echo "<p class='no-posts'>" . __( "Sorry, there are no posts at this time." ) . "</p>";
endif;
I need to add a wrapper div around all the content within the author box.
What filter code do I need to change the genesis_author_box into this:
<section class="author-box" itemprop="author" itemscope="" itemtype="https://schema.org/Person">
<div class="author-box-wrap">
<img alt="" src="" srcset="" class="avatar avatar-150 photo" height="150" width="150">
<h4 class="author-box-title">About <span itemprop="name">Author Name</span></h4>
<div class="author-box-content" itemprop="description">Description Text</div>
</div>
</section>
Here is the default Genesis markup:
<section class="author-box" itemprop="author" itemscope="" itemtype="https://schema.org/Person">
<img alt="" src="" srcset="" class="avatar avatar-150 photo" height="150" width="150">
<h4 class="author-box-title">About <span itemprop="name">Author Name</span></h4>
<div class="author-box-content" itemprop="description">Description Text</div>
</section>
Here is the code that assembles the default Genesis markup:
/**
* Echo the the author box and its contents.
*
* The title is filterable via `genesis_author_box_title`, and the gravatar size is filterable via
* `genesis_author_box_gravatar_size`.
*

My PHP is really rough... Thank you for your help!
Give this a try:
add_filter( 'genesis_author_box', 'my_filter_author_box', 10, 3 );
function my_filter_author_box( $output, $context ) {
$output = preg_replace( '/<section (.+?)>(.+)<\/section>/ms', '<section $1><div class="author-box-wrap">$2</div></section>', $output );
return $output;
}
It may be worth reconsidering why you need to add the inner wrapping div and see if you can work out a better way to style it instead.
I have problem with WP shortcodes.

Please help...
I wanna help but I really dont understand your question.
try change define('WP_DEBUG', true); and see where the problem is.
add_shortcode('check', 'check_scode');
function check_scode($atts){
return '<h1>its working</h1>';
}
add above script test to the bottom of your functions.php in wp-content/themes/your-themes
and put this shortcode
[check]
or with php code, check if your shortcode registered,
if ( ! function_exists( 'check_shortcode' ) ) :
function check_shortcode( $code = '' ) {
global $shortcode_tags;
if ( $code && array_key_exists( $code, $shortcode_tags ) ){
return true;
}
}
endif;
put in the bottom of your functions.php and add this script somewhere,
<?php
if(check_shortcode('gallery_bank')) {
echo '<h1>Shortcode found</h1>';
}else{
echo '<h1>Shortcode <b>not Registered<b></h1>';
}
?>
you should check your theme, search theme check in plugin-install page
I've purchased a theme and the blog excerpt works fine on their demo site, but not on my website's blog overview page.
this is the code I found, but this is the wordpress post-template.php
The theme does not have any blog settings which leads me to think it's a wordpress issues?
Hopre someone can help,
Many thanks!
P.S. Php newbie so please explain how I can fix this.

By default the_excerpt() return the text in the excerpt field. Though you can use a filter to change what it returns:
add_filter( 'get_the_excerpt', 'my_custom_excerpt' );
It will trigger this function when the_excerpt() will be called:
function my_custom_excerpt($excerpt) {
if(empty($excerpt)) {
return get_custom_excerpt();
} else {
return $excerpt;
}
}
That way a custom excerpt will be used if the excerpt field is empty. Here is the code for get_custom_excerpt (it will do a "smart" ceasure):
function print_excerpt($length)
{
global $post;
$text = $post->post_excerpt;
if ( '' == $text ) {
$text = get_the_content('');
$text = apply_filters('the_content', $text);
$text = str_replace(']]>', ']]>', $text);
}
$text = strip_shortcodes($text);
$text = strip_tags($text, '<a>'); // change this to the tags you want to keep
if (preg_match('/^.{1,'.$length.'}\b/s', $text, $match))
$text = $match[0];
$excerpt = reverse_strrchr($text, array('.','!'), 1, 100);
if($excerpt) {
echo apply_filters('the_excerpt',$excerpt);
} else {
echo apply_filters('the_excerpt',$text.'...');
}
}
function reverse_strrchr($haystack, $needle, $trail, $offset=0)
{
return strrposa($haystack, $needle, $offset) ? substr($haystack, 0, strrposa($haystack, $needle, $offset) + $trail) : false;
}
// strrpos in Array mode
function strrposa($haystack, $needles=array(), $offset=0)
{
if(!is_array($needles))
$needles = array($needles);
foreach($needles as $query) {
if(strrpos($haystack, $query, $offset) !== false)
return strrpos($haystack, $query, $offset);
}
return false;
}
I run a wordpress multisite on ayp.no and I am trying to figure out a way to present all subsites with logos and recent posts from all blogs, I know there is a wpmudev premium plugin for this, but I was hoping there was some coding i could do myself (well, obviously not myself, but at least ask here and see)..
First, we need a function to get all sites, with that at hand we iterate thought the array of sites and pull the information with wp_get_recent_posts() (which is a customized version of get_posts()).
Use the following as a Must Use plugin, so the function b5f_print_recent_posts() is available throughout the network:
<?php
/**
* Plugin Name: Recent Network Posts
* Plugin URI: http://stackoverflow.com/q/23713801/1287812
* Description: Creates a function that lists recent posts from all sites of the network. Call it in another plugins or themes.
* Author: brasofilo

echo '<h3>' . $blog['name'] . ' - ' . $blog['domain'] . ' - ' . $blog['desc'] . '</h3>';
$posts = wp_get_recent_posts( array(), OBJECT );
if( $posts )
{
foreach( $posts as $post )
{
printf(
'- %s<br />',
get_permalink( $post->ID ),
$post->post_title
);
}
}
}
switch_to_blog( $current_blog_id );
}

You can add the following network dashboard widget in the previous plugin to test it out:
add_action( 'wp_network_dashboard_setup', 'dashboard_setup_so_23713801' );
