About adding custom search function

In elFinder 2.1.38 or later, you can add custom search functions such as searching from content metadata.

Setting client options

Add the definition of the custom search method to the client option.

opts = {
    url  : 'php/connector.php',
    commandsOptions : {
        search : {
            // Additional search types
            searchTypes : {
                // "SearchMime" is implemented in default
                SearchMime : {           // The key is search type that send to the connector
                    name : 'btnMime',    // Button text to be processed in i18n()
                    title : 'searchMime' // Button title to be processed in i18n()
                },
                // This is custom search method for a function `searchMatchContents()` of your customized volume driver
                Contents : {
                    name : 'MetaData',
                    title : 'Do serach contents of meta data.'
                }
            }
        }
    }
}

Add function to volume driver

Add search matching method searchMatchContents() to your customized volume driver.

This function must return true or false as to whether or not it matches the condition.

protected function searchMatchContents($name, $query, $path) {
    $match = true; // or false
    return $match;
}
