I'm creating a custom CSV importer for a client and the pictures are added, however the thumbnails aren't being generated properly. After using a plugin like Regenerate Thumbnails they do show correctly.
Here is the code in which I add the attachment and link it to the post.
$uploadDir = 'wp-content/uploads/importedproductimages/';
$siteurl = get_option('siteurl');
$thumbnail = 'importedproductimages/' . $name;
$filename = 'importedproductimages/' . $name;
$wp_filetype = wp_check_filetype($filename, null);
$attachment = array(
'post_author' => 1,
'post_date' => current_time('mysql'),
'post_date_gmt' => current_time('mysql'),
'post_mime_type' => $wp_filetype['type'],
'post_title' => $filename,
'comment_status' => 'closed',
'ping_status' => 'closed',
'post_content' => '',
'post_status' => 'inherit',
'post_modified' => current_time('mysql'),
'post_modified_gmt' => current_time('mysql'),
'post_parent' => $post_id,
'post_type' => 'attachment',
'guid' => $siteurl.'/'.$uploadDir.$name
);
$attach_id = wp_insert_attachment( $attachment, $filename, $post_id );
$attach_data = wp_generate_attachment_metadata( $attach_id, $thumbnail );
wp_update_attachment_metadata( $attach_id, $attach_data );
// add featured image to post
add_post_meta($post_id, '_thumbnail_id', $attach_id);
Why aren't the thumbnails being generated properly? Thank you in advance.
EDIT:
I have also included image.php like so:
require_once(ABSPATH . 'wp-admin/includes/image.php');
This ended up working for me:
function createnewproduct($product)
{
$new_post = array(
'post_title' => $product['Product'],
'post_content' => $product['Long_description'],
'post_status' => 'publish',
'post_type' => 'product'
);
$skuu = $product['SKU'];
$post_id = wp_insert_post($new_post);
update_post_meta($post_id, '_sku', $skuu );
update_post_meta( $post_id, '_regular_price', $product['ourPrice'] );
update_post_meta( $post_id, '_manage_stock', true );
update_post_meta( $post_id, '_stock', $product['Qty'] );
update_post_meta( $post_id, '_weight', $product['Weight'] );
if (((int)$product['Qty']) > 0) {
update_post_meta( $post_id, '_stock_status', 'instock');
}
$dir = dirname(__FILE__);
$imageFolder = $dir.'/../import/';
$imageFile = $product['ID'].'.jpg';
$imageFull = $imageFolder.$imageFile;
// only need these if performing outside of admin environment
require_once(ABSPATH . 'wp-admin/includes/media.php');
require_once(ABSPATH . 'wp-admin/includes/file.php');
require_once(ABSPATH . 'wp-admin/includes/image.php');
// example image
$image = 'http://localhost/wordpress/wp-content/import/'.$product['ID'].'.jpg';
// magic sideload image returns an HTML image, not an ID
$media = media_sideload_image($image, $post_id);
// therefore we must find it so we can set it as featured ID
if(!empty($media) && !is_wp_error($media)){
$args = array(
'post_type' => 'attachment',
'posts_per_page' => -1,
'post_status' => 'any',
'post_parent' => $post_id
);
// reference new image to set as featured
$attachments = get_posts($args);
if(isset($attachments) && is_array($attachments)){
foreach($attachments as $attachment){
// grab source of full size images (so no 300x150 nonsense in path)
$image = wp_get_attachment_image_src($attachment->ID, 'full');
// determine if in the $media image we created, the string of the URL exists
if(strpos($media, $image[0]) !== false){
// if so, we found our image. set it as thumbnail
set_post_thumbnail($post_id, $attachment->ID);
// only want one image
break;
}
}
}
}
}
