I have an entity called CV which is used to store uploaded CVs. The entity is created and referenced on the user profile using inline entity form. I need to get the fid for the cv so I can do this:

$uri = file_load($fid)->uri;
$file_name = file_load($fid)->filename;
$path = file_create_url($uri);

I've tried to use entity_metadata_wrapper, but I'm not sure how to actually access the correct field. This is an example of what I've been trying:

$wrapper = entity_metadata_wrapper('candidate_cv', $cv);
$cv_file = $wrapper->field_candidate_cv->value();   

Which returns this error:

EntityMetadataWrapperException: Unknown data property field_candidate_cv.

Update: I have managed to get the title of the entity using this:

$cv_wrapper = entity_metadata_wrapper('user', $user);
$cv_upload = array();
foreach ($cv_wrapper->field_cv->value() as $index => $feature) {
    $cv_upload[] = $feature->title;
echo title[0];

But I can't get to the fid of the file field which is field_candidate_cv.

$cv_wrapper = entity_metadata_wrapper('user', $user);
   $cv_upload = array();
   foreach ($cv_wrapper->field_cv->value() as $index => $feature) {
        $cv_upload[] = $feature->field_candidate_cv;
    $fid = $cv_upload[0]['fid'];

$fid prints nothing.

However, in this $fid prints Array:

 $fid = $cv_upload[0];
  • It seems that your entity is not properly defined or that entiy has no field called field_candidate_cv

  • It definitely has that field, so how do I properly define the entity?

  • try to access the property without metadata wrapper en check if that approach works

  • I tried accessing the field with metadata wrapper but it returned this: 'Warning: array_flip(): Can only flip STRING and INTEGER values! in EntityCacheControllerHelper::entityCacheLoad()'

$cv_wrapper = entity_metadata_wrapper('user', $user);
$cv_upload = array();
foreach ($cv_wrapper->field_cv->value() as $feature) {
    $cv_upload[] = $feature->field_candidate_cv;
$fid = $cv_upload[0]['und'][0]['fid'];

Printed the array of $cv_upload using:

drupal_set_message('<pre>'. print_r($cv_upload, TRUE) .'</pre>');
