Not getting file upload to work

By hunteeer 3224 days ago

Hi folks,

started to work with elgg currently and trying to make a plugin that handles it's own "types" (elggObject + metadata). I managed to add all the fields I needed, but I can't make elgg upload iamges/icons/w.e. thei're called.

$form = elgg_view("input/file", array("name" => "icon"));

echo elgg_view('input/form', array(
           'action'    => 'action/text_type/save',
           'enctype'    => 'multipart/form-data',
           'body'        => $form));

Is working, except in HTML the enctype is missing and (I believe) therefore uploading images isn't working ($_FILES on action page and get_uploaded_file('icon') both empty). What am I doing wrong?

That should be working. Try using elgg_view_form(), and if it works, report the issue on github.

Thanks. While applying your suggestion I found the error I made, but I have a problem getting/displaying these images now:

$has_uploaded_icon = (!empty($_FILES['icon']['type']) && substr_count($_FILES['icon']['type'], 'image/'));

    if ($has_uploaded_icon) {

        $icon_sizes = elgg_get_config('icon_sizes');

        $prefix = "test/" . $test_guid;

        $filehandler = new ElggFile();
        $filehandler->owner_guid = $test->owner_guid;
        $filehandler->setFilename($prefix . ".jpg");
        $filehandler->open("write");
        $filehandler->write(get_uploaded_file('icon'));
        $filehandler->close();
        $filename = $filehandler->getFilenameOnFilestore();

        $sizes = array('tiny', 'small', 'medium', 'large', 'master');

        $thumbs = array();
        foreach ($sizes as $size) {
            $thumbs[$size] = get_resized_image_from_existing_file(
                $filename,
                $icon_sizes[$size]['w'],
                $icon_sizes[$size]['h'],
                $icon_sizes[$size]['square']
                );
        }

        if ($thumbs['tiny']) { // just checking if resize successful
            $thumb = new ElggFile();
            $thumb->owner_guid = $test->owner_guid;
            $thumb->setMimeType('image/jpeg');

            foreach ($sizes as $size) {
                $thumb->setFilename("{$prefix}{$size}.jpg");
                $thumb->open("write");
                $thumb->write($thumbs[$size]);
                $thumb->close();
            }

            $test->icontime = time();
        }
    }

to save the image and this in view to display it:

echo elgg_view_entity_icon($vars['entity'], 'master');

results in this error (loosely translated from german to english):

The graphic "http://localhost/sites/elgg/mod/hypeFilestore/servers/icon.php?guid=109&dir_guid=36&path=icons%2F109master.jpg&ts=1491921441&size=master&mac=2ed882adc7599dbd268380cb3a9fcb14fd68141bc8c452e4ee88f92dd9a5a92a" can't be displayed, because it has errors.

(obviously the path is wrong with "icons/" in it, but changing the save function to prefix with "icons" instead of "test" results in same error.

All the methods starting with set (e.g. setIconFromElggFile() ) are undefined.

Got it to work somehow with:

$owner = get_entity($test->owner_guid);

if (!$owner || !($owner instanceof ElggUser) || !$owner->canEdit()) {
     register_error(elgg_echo('icon:upload:fail'));
     forward(REFERER);
}

$error = elgg_get_friendly_upload_error($_FILES['icon']['error']);
if ($error) {     
    register_error($error);
     forward(REFERER);
}

if (!$test->saveIconFromUploadedFile('icon')) {
     register_error(elgg_echo('icon:resize:fail'));
     forward(REFERER);
}

But I want to store the images in their own directory instead of .../icons/...

entity:icon:file, <entity_type>

Triggered by ElggEntity::getIcon() and allows plugins to provide an alternative ElggIcon object that points to a custom location of the icon on filestore. The handler must return an instance of ElggIcon or an exception will be thrown.
