问题描述：

I am using a simple wordpress shortcode

function my_recent_post()
{
echo \'hello\';
}
add_shortcode( \'recent\', \'my_recent_post\' );

with the shortcode [recent] and its working fine and visible in front page,

but the problem is, its printing the hello in the dashboard also.

Update:

I was actually trying to show posts, so can you help me with this, because it renders the lists of posts in the dashboard itself like the \"hello\". I tried:

function lorem_function() { 
global $post; 
$args = array( \'posts_per_page\' => 10, \'order\'=> \'ASC\', \'orderby\' => \'title\' ); 
$postslist = get_posts( $args ); 
foreach ( $postslist as $post ) : 
setup_postdata( $post ); ?>
<div> 
<?php the_date(); ?> <br /> <?php the_title(); ?> <?php the_excerpt(); ?> 
</div> 
<?php endforeach; 
wp_reset_postdata(); 
return; 
} 
add_shortcode(\'lorem\', \'lorem_function\');

我其实是在尝试 显示帖子，你能帮我解决这个问题吗，因为它会在仪表板中呈现帖子列表，就像“你好”一样。 我试过了：</ p> 
  function lorem_function（）{

网友观点：
Based on your comments to me & Nikita Dudarev, what you need to do is create a variable to hold all the post information and then return it. Using the function you posted as an example:
function lorem_function() { 
global $post; 
$args = array( \'posts_per_page\' => 10, \'order\'=> \'ASC\', \'orderby\' => \'title\' ); 
$postslist = get_posts( $args ); 
// create a variable to hold the post information
$html =\\\"\\\";
foreach ( $postslist as $post ) : 
setup_postdata( $post ); 
$backgroundstyle = \\\"\\\"; 
// get the featured image and set it as the background
if ( has_post_thumbnail() ) { // make sure the post has a featured image
$imageurl = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), \'medium\' ); // you can change \\\"medium\\\" to \\\"thumbnail or full depending on the size you need
// add the css for the background image. You can include background-size etc ad required
$backgroundstyle = \\\"background-image: url(\'\\\".$imageurl[0].\\\"\');\\\";
}
// add the information to the variable
$html .= \'<div style=\\\"\'.$backgroundstyle.\'\\\">\';
$html .= get_the_date();
$html .= \\\"<br />\\\";
$html .= get_the_title();
$html .= get_the_excerpt();
$html .= \\\"</div>\\\";
endforeach; 
wp_reset_postdata(); 
return $html; 
} 
add_shortcode(\'lorem\', \'lorem_function\');
Note that the_date(), the_title() and the_excerpt() all display the information (just like echo). 
Instead you must use get_the_date(), get_the_title() and get_the_excerpt() - these get the same information, but instead of displaying it directly, they return it as a variable which you can then store in your html string to be returned.
Update: 
As you don\'t want to use the variable name on each line for whatever reason, you can do it like this:
$html .= \\\"<div>\\\".get_the_date().\\\"<br />\\\".get_the_title().get_the_excerpt().\\\"</div>\\\";
I\'m not sure why you specifically want to change it to do that - it makes absolutely no difference to how it works, it just makes it harder to read and identify any errors :-)
    
###
Your function must return a value, not output
function my_recent_post()
{
return \'hello\';
}
add_shortcode( \'recent\', \'my_recent_post\' );
