wordpress短代码也在仪表板中呈现内容
问题描述：
I am using a simple wordpress shortcode
|
1 2 3 4 5 6 |
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.
below is the screenshot, can anyone please help.
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:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
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\'); |

Using the function you posted as an example:</p> <pre><code>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:
|
1 2 |
$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

1 2 3 4 5 6 |
function my_recent_post() { return \'hello\'; } add_shortcode( \'recent\', \'my_recent_post\' ); |
