I am developer of the plugin Leaflet Maps Marker (http://www.mapsmarker.com - "Pin, organize & show your favorite places through OpenStreetMap, OGD Vienna or any custom WMTS-map") and have one question: the plugin contains about 100 marker icons from Maps Icons Collection (mapicons.nicolasmollet.com) which can be used to mark your favorite places.
These icons are stored in wp-content\plugins\leaflet-mapsmarker\img\mapicons. Now users can upload other own icons from the collection (which consist of more than 700 icons). Problem is, that if the users upload the custom icons to the plugins-directory and I release an plugin update in the future, the uploaded icons get deleted and have to be uploaded again by the user.
So I started working on moving the mapsicons-directory to wp-content/uploads/leaflet-maps-marker-icons. Creating a directory works quite fine with the wordpress function wp_mkdir_p():
$target = ABSPATH . 'wp-content/uploads/leaflet-maps-marker-icons';
wp_mkdir_p( $target );
as a next step, I wanted to move the directory from plugins by also using the (undocumented) wordpress file api function copy_dir():
$source = WP_PLUGIN_DIR . '/' . end(explode('/', dirname(__FILE__))) . '/img/mapicons'; //allows plugin directory names other than leaflet-maps-marker
$target = ABSPATH . 'wp-content/uploads/leaflet-maps-marker-icons';
copy_dir($source, $target, $skip_list = array() );
Unfortunately this didnt work - I get the error:
Fatal error: Call to a member function dirlist() on a non-object in /wp-current/wp-admin/includes/file.php on line 756
Has anyone here used this function in one of his projects before and knows how to use it correctly? or: do you know any other safe ways to copy/move files using wordpress functions? I don´t want to use PHP command directly, as from my experience, there are too many possible configurations of webservers leading to increased support requests (safemode on/off, having to enter ftp credentials...).
Any help is really appreciated!
To be complete, here is the code for the function copy_dir() from file.php:
function copy_dir($from, $to, $skip_list = array() ) {
global $wp_filesystem;
$dirlist = $wp_filesystem->dirlist($from);
$from = trailingslashit($from);
$to = trailingslashit($to);
$skip_regex = '';
foreach ( (array)$skip_list as $key => $skip_file )
$skip_regex .= preg_quote($skip_file, '!') . '|';
if ( !empty($skip_regex) )
$skip_regex = '!(' . rtrim($skip_regex, '|') . ')$!i';
foreach ( (array) $dirlist as $filename => $fileinfo ) {
if ( !empty($skip_regex) )
if ( preg_match($skip_regex, $from . $filename) )
continue;
if ( 'f' == $fileinfo['type'] ) {
if ( ! $wp_filesystem->copy($from . $filename, $to . $filename, true, FS_CHMOD_FILE) ) {
// If copy failed, chmod file to 0644 and try again.
$wp_filesystem->chmod($to . $filename, 0644);
if ( ! $wp_filesystem->copy($from . $filename, $to . $filename, true, FS_CHMOD_FILE) )
return new WP_Error('copy_failed', __('Could not copy file.'), $to . $filename);
}
} elseif ( 'd' == $fileinfo['type'] ) {
if ( !$wp_filesystem->is_dir($to . $filename) ) {
if ( !$wp_filesystem->mkdir($to . $filename, FS_CHMOD_DIR) )
return new WP_Error('mkdir_failed', __('Could not create directory.'), $to . $filename);
}
$result = copy_dir($from . $filename, $to . $filename, $skip_list);
if ( is_wp_error($result) )
return $result;
}
}
return true;
}
updated code (as within comments code was not formatted properly)
WP_Filesystem();
$target = ABSPATH . 'wp-content/uploads/leaflet-maps-marker-icons';
if (!is_dir($target)) //check for multisite installations
{
wp_mkdir_p( $target );
$source = WP_PLUGIN_DIR . '/' . end(explode('/', dirname(__FILE__))) . '/img/mapicons';
copy_dir($source, $target, $skip_list = array() );
$zipfile = ABSPATH . 'wp-content/uploads/leaflet-maps-marker-icons/mapicons.zip';
unzip_file( $zipfile, $target );
}
