I’ve tried to use entity wrapper to create a new node and insert the values into the fields, but I get an error.

    <?php $values_entity = array(   'type' => 'anuncio',   'uid' => $userid,   'status' => 1,   'comment' => 1,   'promote' => 0, ); $entity = entity_create('node', $values_entity); // The entity is now created, but we have not yet simplified use of it. // Now create an entity_metadata_wrapper around the new node entity // to make getting and setting values easier $ewrapper = entity_metadata_wrapper('node', $entity); // Using the wrapper, we do not have to worry about telling Drupal // what language we are using. The Entity API handles that for us. $ewrapper->title->set($values['titulo']); $ewrapper ->field_fecha_inicio->set($values['fecha_inicio']); $ewrapper ->field_duraci_n->set($values['duracion']); $ewrapper ->field_tipo_anuncio->set($values['tipo_anuncio']); // Now just save the wrapper and the entity // There is some suggestion that the 'true' argument is necessary to // the entity save method to circumvent a bug in Entity API. If there is // such a bug, it almost certainly will get fixed, so make sure to check. $ewrapper->save(); ?> 

EntityMetadataWrapperException: Invalid data value given. Be sure it matches the required data type and format. en EntityMetadataWrapper->set() (línea 122 de /opt/lampp/htdocs/tentu/ataria/sites/all/modules/entity/includes/entity.wrapper.inc).

I’ve tried also to insert the values of the field this way:

<?php     $node = new stdClass();     $node->nid = NULL;     $node->vid = NULL;     $node->type = "anuncio";   //    node_object_prepare($node); // Sets some defaults. Invokes hook_prepare() and hook_node_prepare().       $node->language = $language_url;// Or e.g. 'en' if locale is enabled       $node->title = $values['titulo'];       $node->uid = $userid;       $node->status = 1; //(1 or 0): published or not       $node->created = REQUEST_TIME;       $node->changed = REQUEST_TIME;       $node->promote = 0; //(1 or 0): promoted to front page       $node->comment = 1; // 0 = comments disabled, 1 = read only, 2 = read/write       $node->sticky =0;       $node->field_fecha_inicio[$node->language][]['value'] = $values['fecha_inicio'];       //$node->field_posicion2[$node->language][]['und'] = $form_state['values']['fecha_inicio'];       $node->field_duraci_n[$node->language][]['value']= $values['duracion'];       $node->field_municipio[$node->language][0]['tid'] = $values['municipios'];       $node->field_tem_tica[$node->language][0]['tid'] = $values['tematicas'];       $node->field_importe[$node->language][0]['value'] = $values['importe'];       $node->field_texto_anuncio[$node->language][0]['value'] = $values['texto'];       $node->field_g_nero[$node->language][0]['value'] = $values['genero'];       $node->field_ubicacion_anuncio[$node->language][0]['value'] = $ubicacion;       $node->field_tipo_anuncio [$node->language][0]/*['value']*/= $tipo;   // Entity reference field   // 'node' is default,   // Other possible values are "user" and  "taxonomy_term"   node_submit($node); // Prepare node for saving   node_save($node); ?> 

I can create the node with the last code, but I can’t save the values into the fields. I have seen in my database that the name of the fields isn’t for example, field_fecha_inicio, instead, I have field_data_field_fecha_inicio and field_revision_field_fecha_inicio.

How can I insert the values into the fields?

ANSWERD:

$node = new stdClass();     $node->title = $values['titulo'];     $node->language = $values['idioma'];     $node->uid = $userid;     $node->status = 1; //(1 or 0): published or not     $node->promote = 0; //(1 or 0): promoted to front page     $node->comment = 1; // 0 = comments disabled, 1 = read only, 2 = read/write     $node->sticky = 0;          $node->type = "anuncio";     node_object_prepare($node);     $node->field_texto_anuncio[LANGUAGE_NONE][] = $values['texto'];          $node->field_fecha_inicio[LANGUAGE_NONE][]['value'] = $values['fecha_inicio'];     $node->field_duraci_n[LANGUAGE_NONE][]['value'] = $values['duracion'];     $node->field_municipio[$values['idioma']][]['tid'] = $values['municipios'];     $node->field_tem_tica[$values['idioma']][]['tid'] = $values['tematicas'];     $node->field_importe[LANGUAGE_NONE][]['value'] = $values['importe'];      $node->field_g_nero[LANGUAGE_NONE][]['tid']= $values['genero'];     $node->field_url_del_anuncio[LANGUAGE_NONE][]['value'] = $values['url'];     $node->field_ubicacion_anuncio[LANGUAGE_NONE][]['tid'] = $ubicacion;     $node->field_tipo_anuncio[LANGUAGE_NONE][]['tid']= $tipo;          $node = node_submit($node); // Prepare node for saving     node_save($node);
