I’m creating a custom post submit form for wordpress and at the moment I can create the post and have the image uploaded and attached to the post but the next step im struggling at - I’m looking to have the uploaded image automatically displayed on the post, ive looked into the featured image option but just can’t get it to work
$my_post = array();
$my_post['post_title'] = $newid;
$my_post['post_content'] = $imageurl1.$imageurl.$config_basedir.$uploaddir.$id . ".gif". $imageurl2;
$my_post['post_author'] = 1;
$my_post['post_status'] = draft;
$my_post['post_category'] = array($a);
// Insert the post into the database
$post_id = wp_insert_post($my_post);
//
$wp_filetype = wp_check_filetype(basename($id . ".gif"), null );
$attachment = array();
$attachment['post_mime_type'] = $wp_filetype['type'];
$attachment['post_title'] = $newid;
$attachment['post_content'] = '';
$attachment['post_status'] = 'inherit';
$attach_id = wp_insert_attachment($attachment, $id . ".gif", $post_id)
require_once(ABSPATH . "wp-admin" . '/includes/image.php');
$attach_data = wp_generate_attachment_metadata($attach_id, $filename);
wp_update_attachment_metadata($attach_id, $attach_data);
set_post_thumbnail($post_id, $attach_id);
//
wp_redirect( site_url()."?p=$post_id" ); exit();
Any help is appreciated
Use set_post_thumbnail. You can pass in the post object or ID. Thumbnail ID is the media attachment ID.
set_post_thumbnail( $post, $thumbnail_id );

I have an html form in front end in WordPress page. A user uploads the image in the form which should be set as featured image in CPT.
This is the upload field in the form:
<input id="uploadBtn" type="file" class="upload" name="uploadBtn"/>
I have tried this code :
// Add Featured Image to Post
$image_url = 'http://s.wordpress.org/style/images/wp-header-logo.png';// Define the image URL here
$image_name = 'wp-header-logo.png';
$upload_dir = wp_upload_dir(); // Set upload folder
$image_data = file_get_contents($image_url); // Get image data
$unique_file_name = wp_unique_filename( $upload_dir['path'], $image_name); // Generate unique name
$filename = basename( $unique_file_name ); // Create image file name
// Check folder permission and define file location
if( wp_mkdir_p( $upload_dir['path'] ) ) {
$file = $upload_dir['path'] . '/' . $filename;
} else {
$file = $upload_dir['basedir'] . '/' . $filename;
}
// Create the image file on the server
file_put_contents( $file, $image_data );
// Check image file type
$wp_filetype = wp_check_filetype( $filename, null );
// Set attachment data
$attachment = array(
'post_mime_type' => $wp_filetype['type'],
'post_title' => sanitize_file_name( $filename ),
'post_content' => '',
'post_status' => 'inherit'
);
// Create the attachment
$attach_id = wp_insert_attachment( $attachment, $file, $new_post_id );
// Include image.php
require_once(ABSPATH . 'wp-admin/includes/image.php');
// Define attachment metadata
$attach_data = wp_generate_attachment_metadata( $attach_id, $file );
// Assign metadata to attachment
wp_update_attachment_metadata( $attach_id, $attach_data );
// And finally assign featured image to post
set_post_thumbnail( $new_post_id, $attach_id );
It works well if I have image url, name and such. However, I need to make it work for any image that user uploads. Is there any way to get image url and name from $_FILES? Any help would be appreciated. Thanks!
You need either post object or post ID for the set_post_thumbnail() function. The function wp_insert_post() will return post id on success. You can use that post id to set the thumbnail image.
Here is the modification for your last couple of lines
$post_id = wp_insert_post( $my_post );
if(!$post_id){
// post insertion was failed. Handle it here
}
//Set Image as thumbnail
set_post_thumbnail($post_id, $attach_id);
I have some post id's and I want to set these posts' featured images from same url.
Here is my adding post codes:
$catid = get_cat_ID("XX Cat");
$my_post = array();
$my_post['post_title'] = $title;
$my_post['post_content'] = $description;
$my_post['post_status'] = 'publish';
$my_post['post_author'] = 1;
$my_post['post_category'] = array( $catid );
$post_id = wp_insert_post( $my_post );
Example: post_id = 1 I want to set featured image to: example.com/image.png
How can I do this?
You can set an image as post featured thumbnail when it is in your media library. To add an image in your media library you need to upload it to your server.
try this code:
// Add Featured Image to Post
$image_url = 'http://s.wordpress.org/style/images/wp-header-logo.png'; // Define the image URL here
$image_name = 'wp-header-logo.png';
$upload_dir = wp_upload_dir(); // Set upload folder
$image_data = file_get_contents($image_url); // Get image data
$unique_file_name = wp_unique_filename( $upload_dir['path'], $image_name ); // Generate unique name
$filename = basename( $unique_file_name ); // Create image file name
// Check folder permission and define file location
if( wp_mkdir_p( $upload_dir['path'] ) ) {
$file = $upload_dir['path'] . '/' . $filename;
} else {
$file = $upload_dir['basedir'] . '/' . $filename;
}
// Create the image file on the server
file_put_contents( $file, $image_data );
// Check image file type
$wp_filetype = wp_check_filetype( $filename, null );
// Set attachment data
$attachment = array(
'post_mime_type' => $wp_filetype['type'],
'post_title' => sanitize_file_name( $filename ),
'post_content' => '',
'post_status' => 'inherit'
);
// Create the attachment
$attach_id = wp_insert_attachment( $attachment, $file, $post_id );
// Include image.php
require_once(ABSPATH . 'wp-admin/includes/image.php');
// Define attachment metadata
$attach_data = wp_generate_attachment_metadata( $attach_id, $file );
// Assign metadata to attachment
wp_update_attachment_metadata( $attach_id, $attach_data );
// And finally assign featured image to post
set_post_thumbnail( $post_id, $attach_id );

Modified as your requirement:
or that purpose ignore WordPress standard and upload your all post single image on your custom folder and add this image path or direct external image url into post as extra attribute meta field and when you will show post on your theme then just use your img with help of post id.
demo code:
for setting image
<?php
update_post_meta ( 7, 'imgkey', 'www.url.path' );//7 is post id
?>
for getting image on your theme page where you want to show it
<?php
$img_value = get_post_meta( get_the_ID(), 'imgkey', true );
?>
<img src="<?php echo $img_value?>">
Note if you are new in WordPress post custom meta fields then read this article:
https://codex.wordpress.org/Custom_Fields
or
unofficial article about custom fields: https://premium.wpmudev.org/blog/creating-custom-fields-manually
if you have to load an image and then assign as thumbnail of the post, the quicker way is to use media_sideload_image and then set_post_thumbnail
https://developer.wordpress.org/reference/functions/media_sideload_image/
$url = "http://url-of-the-image.jpg";
$post_id = [post id]
$desc = "image description";
$image = media_sideload_image( $url, $post_id, $desc,'id' );
set_post_thumbnail( $post_id, $image );
Just to complement #Naraj answer, if you are working in an external file, remember to add:
require_once(ABSPATH . 'wp-admin/includes/media.php');
require_once(ABSPATH . 'wp-admin/includes/file.php');
require_once(ABSPATH . 'wp-admin/includes/image.php');
if you do not add that you will get an error message saying that media_sideload_image is undefined.
Good evening. I've written a function to programmatically insert a Wordpress post for each of our YouTube videos, using a foreach loop.
Everything is working wonderfully, until I get to inserting the post thumbnail. I am using a function that automatically handles the uploading and inserting of a thumbnail, and associating it with a post (below):
function Generate_Featured_Image($image_url, $post_id) {
$upload_dir = wp_upload_dir();
$image_data = file_get_contents($image_url);
$filename = basename($post_id.'-'.$image_url);
if (wp_mkdir_p($upload_dir['path'])) $file = $upload_dir['path'] . '/' . $filename;
else $file = $upload_dir['basedir'] . '/' . $filename;
file_put_contents($file, $image_data);
$wp_filetype = wp_check_filetype($filename, null );
$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 );
$res1 = wp_update_attachment_metadata( $attach_id, $attach_data );
$res2 = set_post_thumbnail( $post_id, $attach_id );
}
This function does work, but for some odd reason, it only uploads the image from the last video in the loop. For example, if I have 5 videos, 5 posts will be created. Each containing it's own specific information, but the post thumbnail will all be the image from the last (5th) video. None of them have their own thumbnail.
Here's a slimmed down verson of my function that creates the posts:
function createYouTubePost() {
...some other code...
$JSON = file_get_contents('https://www.googleapis.com/youtube/v3/search?order='.$api_order.'&part='.$api_part.'&channelId='.$channel_id.'&maxResults='.$max_results.'&key='.$api_key);
$json_data = json_decode($JSON, true);
foreach ($json_data['items'] as $data) {
$video_id = $data['id']['videoId'];
$video_title = $data['snippet']['title'];
$video_description = $data['snippet']['description'];
$video_thumb_url = $data['snippet']['thumbnails']['high']['url'];
$video_thumb_width = $data['snippet']['thumbnails']['high']['width'];
$video_thumb_height = $data['snippet']['thumbnails']['high']['height'];
$video_publish_date = $data['snippet']['publishedAt'];
$args = array(
'post_title' => substr($video_title, 0, strrpos($video_title, '(')),
'post_content' => $video_description,
'post_status' => 'publish',
'post_type' => 'download',
);
if (!if_download_exists(substr($video_title, 0, strrpos($video_title, '(')))) {
$new_post_id = wp_insert_post($args, true);
if ($new_post_id == 0) {
echo '<br>Could not create the post.';
var_dump($new_post_id);
}
else {
Generate_Featured_Image($video_thumb_url, $new_post_id);
...lots of code to update various post_meta fields...
echo '<br>New post created.<br>';
var_dump($new_post_id);
}
}
}
}
Here you can see the media attachments and how they're all the same:
And here are the individual posts that were created:
As you can see, each image is assigned to it's respective post, but the image is the same.
I have even tried setting the filename of each picture with a unique ID so that they're all different, but that didnt help. I have also confirmed that the image url's that I am passing to the function are all different.
My question is, if I am using my function Generate_Featured_Image() in a foreach loop, and provding it with unique information, why is it only using the last picture in the loop?
Thanks for any help!
I went with another solution. Wordpress' media_sideload_image() function works and is a more straight forward solution for my situation.
Here is the function that I'm now using to assign a thumbnail to a post:
function generateFeaturedImage($image_url, $post_id) {
// required libraries for media_sideload_image
require_once(ABSPATH . 'wp-admin/includes/file.php');
require_once(ABSPATH . 'wp-admin/includes/media.php');
require_once(ABSPATH . 'wp-admin/includes/image.php');
// $post_id == the post you want the image to be attached to
// $video_thumb_url == the vimeo video's thumb url
// $description == optional description
// load the image
$result = media_sideload_image($image_url, $post_id);
// then find the last image added to the post attachments
$attachments = get_posts(array('numberposts' => '1', 'post_parent' => $post_id, 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => 'ASC'));
if (sizeof($attachments) > 0) {
// set image as the post thumbnail
set_post_thumbnail($post_id, $attachments[0]->ID);
}
}
Here's the link to the stack exchange solution that I found.
I am scraping a site and putting data in my WP site.
There are lots of images in those posts.
I want that when importing that scraped data into my WP site,
I want to link images into my site directly from that external URL instead of downloading image to my server.
I am grammatically importing scraped data to my site.
Here is that part of adding image
// for image
$ins_q = "INSERT INTO wpxw_posts (post_author, post_date, post_date_gmt, post_content, post_title, post_excerpt, post_status, "
. "comment_status, ping_status,"
. "post_password, post_name, to_ping, pinged, post_modified,post_modified_gmt, post_content_filtered,post_parent,"
. "guid,menu_order,post_type,"
. "post_mime_type,comment_count) VALUES(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)";
$sth = $conn->prepare($ins_q);
if (!$sth->execute(array(
$post_author, $date, $date, "", sanitize_title_with_dashes($image_name), "", "inherit", "open", "closed", '',
str_replace(".", "-", $image_name), '', '', $date, $date, '', $post_id,
"http://photos2.zillowstatic.com/p_f/ISdc6hruhctopo0000000000.jpg"
, 0, "attachment", "image/jpeg", 0
))) {
echo "<h1>Error</h1>";
print_r($sth->errorInfo());
exit();
}
}
MY PROBLEM is that when adding external link to image, images do not show on my post. How can I show images from external resources?
// Add Featured Image to Post
$image_url = 'http://s.wordpress.org/style/images/wp-header-logo.png'; // Define the image URL here
$upload_dir = wp_upload_dir(); // Set upload folder
$image_data = file_get_contents($image_url); // Get image data
$filename = basename($image_url); // Create image file name
// Check folder permission and define file location
if( wp_mkdir_p( $upload_dir['path'] ) ) {
$file = $upload_dir['path'] . '/' . $filename;
} else {
$file = $upload_dir['basedir'] . '/' . $filename;
}
// Create the image file on the server
file_put_contents( $file, $image_data );
// Check image file type
$wp_filetype = wp_check_filetype( $filename, null );
// Set attachment data
$attachment = array(
'post_mime_type' => $wp_filetype['type'],
'post_title' => sanitize_file_name( $filename ),
'post_content' => '',
'post_status' => 'inherit'
);
// Create the attachment
$attach_id = wp_insert_attachment( $attachment, $file, $post_id );
// Include image.php
require_once(ABSPATH . 'wp-admin/includes/image.php');
// Define attachment metadata
$attach_data = wp_generate_attachment_metadata( $attach_id, $file );
// Assign metadata to attachment
wp_update_attachment_metadata( $attach_id, $attach_data );
// And finally assign featured image to post
set_post_thumbnail( $post_id, $attach_id );
I have the following function to copy across a post as it's created on one site, to then move it over to a specific multisite blog:
function copy_across_to_multisite( $post_id ) {
// If this is just a revision, don't send the email.
if ( wp_is_post_revision( $post_id ) )
return $post_id;
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE)
return $post_id;
if ($post_id && get_current_blog_id() == 1) {
$post = get_post($post_id, ARRAY_A); // get the original post
if ($post->post_status == 'trash' || $post->post_status == 'auto-draft') {
return $post_id;
}
$meta = get_post_meta($post_id);
$post_thumbnail_id = get_post_thumbnail_id($post_id);
$post_thumbnail = get_post($post_thumbnail_id, ARRAY_A);
$post['ID'] = ''; // empty id field, to tell wordpress that this will be a new post
$post_thumbnail['ID'] = '';
switch_to_blog(2); // switch to target blog
$inserted_post_id = wp_insert_post($post); // insert the post
$inserted_thumbnail = wp_insert_post($post_thumbnail);
foreach($meta as $key=>$value) {
update_post_meta($inserted_post_id,$key,$value[0]);
}
set_post_thumbnail($inserted_post_id, $inserted_thumbnail);
restore_current_blog(); // return to original blog
}
}
add_action( 'save_post', 'copy_across_to_multisite' );
This works great, but it doesn't bring across the featured image; I'm assuming because I need to also move the featured image into the upload folder for that multisite? The image does come across in the media library (albeit with no thumbnail and linking back to the other site - which I don't mind) but doesn't 'attach' onto the post and show up as a featured image.
Can anyone help out with this? Has anyone done anything similar? Thanks
Well, finally managed to (pretty much) cobble together a solution.
So in case anyone needs a similar function, it will take a little tweaking depending on your situation (changing the number in the switch_to_blog function as needed).
function copy_across_to_multisite( $post_id ) {
// If this is just a revision, don't send the email.
if ( wp_is_post_revision( $post_id ) )
return $post_id;
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE)
return $post_id;
if ($post_id && get_current_blog_id() == 1) {
$post = get_post($post_id, ARRAY_A); // get the original post
if ($post->post_status['trash'] || $post['post_status'] == 'auto-draft') {
return $post_id;
}
$meta = get_post_meta($post_id);
$post_thumbnail_id = get_post_thumbnail_id($post_id);
$image_url = wp_get_attachment_image_src($post_thumbnail_id, 'full');
$image_url = $image_url[0];
$post['ID'] = ''; // empty id field, to tell wordpress that this will be a new post
switch_to_blog(2); // switch to target blog
$inserted_post_id = wp_insert_post($post); // insert the post
foreach($meta as $key=>$value) {
update_post_meta($inserted_post_id,$key,$value[0]);
}
// Add Featured Image to Post
$upload_dir = wp_upload_dir(); // Set upload folder
$image_data = file_get_contents($image_url); // Get image data
$filename = basename($image_url); // Create image file name
// Check folder permission and define file location
if( wp_mkdir_p( $upload_dir['path'] ) ) {
$file = $upload_dir['path'] . '/' . $filename;
} else {
$file = $upload_dir['basedir'] . '/' . $filename;
}
// Create the image file on the server
file_put_contents( $file, $image_data );
// Check image file type
$wp_filetype = wp_check_filetype( $filename, null );
// Set attachment data
$attachment = array(
'post_mime_type' => $wp_filetype['type'],
'post_title' => sanitize_file_name( $filename ),
'post_content' => '',
'post_status' => 'inherit'
);
// Create the attachment
$attach_id = wp_insert_attachment( $attachment, $file, $post_id );
// Include image.php
require_once(ABSPATH . 'wp-admin/includes/image.php');
// Define attachment metadata
$attach_data = wp_generate_attachment_metadata( $attach_id, $file );
// Assign metadata to attachment
wp_update_attachment_metadata( $attach_id, $attach_data );
// And finally assign featured image to post
set_post_thumbnail( $inserted_post_id, $attach_id );
restore_current_blog(); // return to original blog
