I have created a custom post type (images) for handling event images, to which I have also added a custom image uploader meta field, and everything works exactly the way I want it to, EXCEPT, it breaks jetpack. I know from experience with Jetpack that a plugin may create unexpected output, causing the "-32700" error with jetpack, but i don't know which part of the code is causing it. The code for the image uploader is:
<?php
function add_custom_meta_boxes() {
// Define the custom attachment for posts
add_meta_box(
'wp_image_attachment',
'Custom Attachment',
'wp_image_attachment',
'images',
'side'
);
} // end add_custom_meta_boxes
add_action('add_meta_boxes', 'add_custom_meta_boxes');
function wp_image_attachment() {
wp_nonce_field(plugin_basename(__FILE__), 'wp_image_attachment_nonce');
$html = '<p class="description">';
$html .= 'Upload your image here.';
$html .= '</p>';
$html .= '<input type="file" id="wp_image_attachment" name="wp_image_attachment" value="" size="25">';
echo $html;
} // end wp_image_attachment
function save_custom_meta_data($id) {
/* --- security verification --- */
if(!wp_verify_nonce($_POST['wp_image_attachment_nonce'], plugin_basename(__FILE__))) {
return $id;
} // end if
if(defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) {
return $id;
} // end if
if('page' == $_POST['post_type']) {
if(!current_user_can('edit_page', $id)) {
return $id;
} // end if
} else {
if(!current_user_can('edit_page', $id)) {
return $id;
} // end if
} // end if
/* - end security verification - */
// Make sure the file array isn't empty
if(!empty($_FILES['wp_image_attachment']['name'])) {
// Setup the array of supported file types. In this case, it's just PDF.
$supported_types = array('image/gif', 'image/jpeg', 'image/jpg', 'image/png');
// Get the file type of the upload
$arr_file_type = wp_check_filetype(basename($_FILES['wp_image_attachment']['name']));
$uploaded_type = $arr_file_type['type'];
// Check if the type is supported. If not, throw an error.
if(in_array($uploaded_type, $supported_types)) {
// Use the WordPress API to upload the file
$upload = wp_upload_bits($_FILES['wp_image_attachment']['name'], null, file_get_contents($_FILES['wp_image_attachment']['tmp_name']));
if(isset($upload['error']) && $upload['error'] != 0) {
wp_die('There was an error uploading your file. The error is: ' . $upload['error']);
} else {
add_post_meta($id, 'wp_image_attachment', $upload);
update_post_meta($id, 'wp_image_attachment', $upload);
} // end if/else
} else {
wp_die("The file type that you've uploaded is not an image.");
} // end if/else
} // end if
} // end save_custom_meta_data
add_action('save_post', 'save_custom_meta_data');
function update_edit_form() {
echo ' enctype="multipart/form-data"';
} // end update_edit_form
add_action('post_edit_form_tag', 'update_edit_form');
?>
I know that's a lot of code to be putting here, but I got shouted at last time I linked to pastebin [ ;) ], but any help would be greatly appreciated, as the site is nearly finished, but i'd really like to utilize the Publicize feature of Jetpack, so i'd prefer not to sacrifice it, but I NEED this bit to work.
Many thanks in advance! :)
