WordPress wp_editor featured thumbnail image doesnt show

1 Views

i was developing some theme that could create new post on front end. my issue is that when the “add media” has uploaded the photo, everything works well, except that when i set the “set featured image” for that post is not showing on the “thumbnail” when the post is published.

this is the wp_editor code setup:

<?php 
$setupev = array(
         'media_buttons'=>1, 
         'textarea_name'=>'post_ne', 
         'tinymce' => true );
wp_editor('content here', 'create_nepost', $setupev); 

?>

this is the code i use to publish new post: 

$the_contnt = $_POST['post_ne'];
$new_post = array(
'post_title' => $get_title,
'post_content' => $the_contnt,
'post_date' => date('YmdHis'),
'post_status' => 'publish',
'post_author' => 1,
'post_category' => array(8,5)
);

wp_insert_post( $new_post );

is there some code to add-in to get the attachment thumbnail?

  1. you need to use set_post_thumbnail() function. two things you require for this function are the $post_id which is the id you are providing to wp_insert_post() and $attach_id which is the id of attachment.

    set_post_thumbnail( $post_id, $attach_id );

    you already have $post_id, to find $attach_id

    $attachment = array(

    'post_mime_type' => $wp_filetype['type'],
'post_title' => sanitize_file_name($filename),
'post_content' => '',
'post_status' => 'inherit'`

    );
    $attach_id = wp_insert_attachment( $attachment, $file, $post_id );
    require_once(ABSPATH . 'wp-admin/includes/image.php');
    $attach_data = wp_generate_attachment_metadata( $attach_id, $file );
    wp_update_attachment_metadata( $attach_id, $attach_data );
