media_handle_sideload

Definition:
function media_handle_sideload($file_array, $post_id, $desc = null, $post_data = array() {}

This handles a sideloaded file in the same way as an uploaded file is handled by media_handle_upload()

Parameters

  • array $file_array: Array similar to a $_FILES upload array
  • int $post_id: The post ID the media is associated with
  • string $desc: Description of the sideloaded file
  • array $post_data: allows you to overwrite some of the attachment

Return values

returns:ID of the attachment or a WP_Error on failure

Source code

function media_handle_sideload($file_array, $post_id, $desc = null, $post_data = array()) {

	$overrides = array('test_form'=>false);



	$file = wp_handle_sideload($file_array, $overrides);

	if ( isset($file['error']) )

		return new WP_Error( 'upload_error', $file['error'] );



	$url = $file['url'];

	$type = $file['type'];

	$file = $file['file'];

	$title = preg_replace('/\.[^.]+$/', '', basename($file));

	$content = '';



	// use image exif/iptc data for title and caption defaults if possible

	if ( $image_meta = @wp_read_image_metadata($file) ) {

		if ( trim( $image_meta['title'] ) && ! is_numeric( sanitize_title( $image_meta['title'] ) ) )

			$title = $image_meta['title'];

		if ( trim( $image_meta['caption'] ) )

			$content = $image_meta['caption'];

	}



	$title = isset($desc) ? $desc : '';



	// Construct the attachment array

	$attachment = array_merge( array(

		'post_mime_type' => $type,

		'guid' => $url,

		'post_parent' => $post_id,

		'post_title' => $title,

		'post_content' => $content,

	), $post_data );



	// This should never be set as it would then overwrite an existing attachment.

	if ( isset( $attachment['ID'] ) )

		unset( $attachment['ID'] );



	// Save the attachment metadata

	$id = wp_insert_attachment($attachment, $file, $post_id);

	if ( !is_wp_error($id) )

		wp_update_attachment_metadata( $id, wp_generate_attachment_metadata( $id, $file ) );



	return $id;
