Hi Experts!

I need some simple wordpress file upload code, something like regular file uploader in Wordpress, but I want to include it in my plugin.

Thanks.

Thanks, but I can't use someone else's work in my plugin, I'm looking for some 'standard' file upload code used in Wordpress plugins, I don't need anything fancy.

Don't know why, but nothing displays, I've done exactly what they say on that page, but no results:


<?php
	function custom_field_document_upload() {
            global $post;
        
            $custom         = get_post_custom($post->ID);
            $download_id    = get_post_meta($post->ID, 'document_file_id', true);
        
            echo '<p><label for="document_file">Upload document:</label><br />';
            echo '<input type="file" name="document_file" id="document_file" /></p>';
            echo '</p>';
        
            if(!empty($download_id) && $download_id != '0') {
                echo '<p><a href="' . wp_get_attachment_url($download_id) . '">
                    View document</a></p>';
            }
        }
	add_action('save_post', 'custom_field_document_upload'); //I called the function here, is it the right way?
		
	function custom_field_document_update($post_id) {
            global $post;
        
            if(strtolower($_POST['post_type']) === 'page') {
                if(!current_user_can('edit_page', $post_id)) {
                    return $post_id;
                }
            }
            else {
                if(!current_user_can('edit_post', $post_id)) {
                    return $post_id;
                }
            }
        
            if(!empty($_FILES['document_file'])) {
                $file   = $_FILES['document_file'];
                $upload = wp_handle_upload($file, array('test_form' => false));
                if(!isset($upload['error']) && isset($upload['file'])) {
                    $filetype   = wp_check_filetype(basename($upload['file']), null);
                    $title      = $file['name'];
                    $ext        = strrchr($title, '.');
                    $title      = ($ext !== false) ? substr($title, 0, -strlen($ext)) : $title;
                    $attachment = array(
                        'post_mime_type'    => $wp_filetype['type'],
                        'post_title'        => addslashes($title),
                        'post_content'      => '',
                        'post_status'       => 'inherit',
                        'post_parent'       => $post->ID
                    );
        
                    $attach_key = 'document_file_id';
                    $attach_id  = wp_insert_attachment($attachment, $upload['file']);
                    $existing_download = (int) get_post_meta($post->ID, $attach_key, true);
        
                    if(is_numeric($existing_download)) {
                        wp_delete_attachment($existing_download);
                    }
        
                    update_post_meta($post->ID, $attach_key, $attach_id);
                }
            }
        }
