I have some csv files uploaded as assets and now I need to fopen() them from my plugin.

I have an AssetFileModel but I have not been able to work out how to construct a full path to the file.

I can access the filename like: $asset->filename which gives me my_csv_file.csv but this is not enough for fopen() to find it.

How can I get the absolute path to the asset file?

Or at least a path that I can use with fopen() to find the file?


You can get the rest of the path from your asset's source and folder, I think something like this should do it:

$source = $asset->getSource();

if ($source->type != 'Local')
    throw new Exception(Craft::t('Paths not available for non-local asset sources'));

$sourcePath = $source->settings['path'];
$folderPath = $asset->getFolder()->path;

$assetFilePath = $sourcePath.$folderPath.$asset->filename;

  • Doesn't work for me :( it results in {basePath}uploads/example.png which isn't a valid path obviously – Stalinko Mar 15 '18 at 11:37

Update for Craft 3:

To get the same output as Mike's path above, you can use:

$volumePath = $asset->getVolume()->settings['path'];
$folderPath = $asset->getFolder()->path;
$assetFilePath = Yii::getAlias($volumePath) . $folderPath . $asset->filename;

    This may only work for assets at the top-level of an asset volume. Apt to need an intermediate $folderPath = $asset->getFolder()->path;, like the Craft 2 answer. – August Miller Jun 20 '18 at 15:34

See Asset::getImageTransformSourcePath() for how Craft CMS resolves the real local path. (https://github.com/craftcms/cms/blob/develop/src/elements/Asset.php#L1200)

Should look something like this:

$volume = $this->getVolume();
$assetFilePath = $volume instanceof LocalVolumeInterface
  ? FileHelper::normalizePath($volume->getRootPath() . DIRECTORY_SEPARATOR . $this->getPath())
  : null;
