Elgg 2.0+

This is intended for developers who routinely use csvs for functions such as data imports.

This plugin aims to take much of the legwork out of csv processing. It provides an admin page for uploading/selecting the csv, selecting the function to process the csv, setting csv specific settings, and watching/downloading a log file showing how the script performed.

The form for handling csv functions is found at Admin -> Utilities -> CSV Processing


Install/unzip/clone to the mod directory of your elgg installation

The directory should be named csv_process

Enable the plugin through the admin plugins page


This plugin requires the vroom plugin


There are only 3 steps required to integrate to this plugin

  1. Register a plugin hook handler to declare a callback function

  2. Declare your callback function

  3. Define your callback function

Register your plugin hook handler:

elgg_register_plugin_hook_handler('csv_process', 'callbacks', 'myplugin_csv_callbacks');

Declare your callback function:

function myplugin_csv_callbacks($hook, $type, $return, $params) {	
    $return['myplugin_csv_process'] = elgg_echo('myplugin:handler:label');
    return $return;

The return value is an associative array with your callback function name as the key and a label describing the function as a value. These will be used to populate the dropdown input for selecting how to process the csv.

Define your callback function

 *  @params array()
function myplugin_csv_process($params) {

    static $skipped;

    // you can always know what line you are on with $params
    if ($params['line'] == 1) {
        // first line is our column headers, nothing to do here

    // the $params['last'] flag indicates that there are is no more data
    // this can be used to log any final tallies or information
    // when the 'last' flag is true data will be an empty array
    if ($params['last']) {
        return "{$params['line']} lines processed, {$skipped} skipped users";

    // our data is an array in $params['data']
    // do something with it
    $user = get_user($params['data'][0]);
    if (!$user) {
        return; // nothing to do here

    // we have a user from our data, import something
    $user->food = $params['data'][1];

    // a returned string from the function will automatically be logged
    // but you can always log extra stuff yourself
    csv_process\log("my log message", $params);

    return 'this will also be logged!';

That's all. Sort out what to do with your data and let this plugin handle the interface, logging, row iterations, etc.
