How can we insert multiple values in field values?

Question

$values = $form_state['values'];
    $images = array();
    foreach ($values as $k => $val)
    if (strpos($k, 'images') !== false && $val !== 0) {
        $images[$k] = $val;
        unset($values[$k]);
    } elseif (strpos($k, 'images') !== false)
        unset($values[$k]);   
    $node = new stdClass();
$node->language = LANGUAGE_NONE;
$node->promote = 0;
$node->uid = 1;
$node->type = 'beaches';
    $node->title = $values['location_name'];
    $node->field_location[$node->language][0]['value']=$values['location'];
    $node->field_location_name[$node->language][0]['value']=$values['location_name'];
    $node->field_beaches_continent[$node->language][0]['value']=$values['continent'];
    $node->field_country[$node->language][0]['value']=$values['country'];
    $node->field_about_location[$node->language][0]['value']=$values['description_location'];
    $node->field_travelling_location[$node->language][0]['value']=$values['travelling_details'];
    $node->field_location_facilities[$node->language][0]['value']=$values['location_facilities'];
    $node->field_beach_tag[$node->language][0]['value']=$values['tags'];
    $node->field_longtitude[$node->language][0]['value']=$values['longtitude'];
    $node->field_latitude[$node->language][0]['value']=$values['latitude'];
    foreach ($images as $image) {
    $file = file_load($image);
    $file->status = FILE_STATUS_PERMANENT;
    $node->field_beaches_images[$node->language][0]['value']=$file->fid;
    file_save($file);
    }
    node_object_prepare($node);
node_save($node);
return $node;

edit submit action:-

global $user;
$values = $form_state['values'];    
$updatenode=node_load($values['beach_id']);

unset($values['submit']);
unset($values['form_build_id']);
unset($values['form_token']);
unset($values['form_id']);
unset($values['op']);

$clid = $values['beach_id'];
unset($values['beach_id']);;
$images = array();
foreach ($values as $k => $val){
    if (strpos($k, 'images') !== false && $val !== 0) {
        $images[$k] = $val;
        unset($values[$k]);
    } elseif (strpos($k, 'images') !== false)
        unset($values[$k]);
}
   if($updatenode->nid==$clid  ){
    $updatenode->title = $values['location_name'];
    $updatenode->field_location[$updatenode->language][0]['value']=$values['location'];
    $updatenode->field_location_name[$updatenode->language][0]['value']=$values['location_name'];
    $updatenode->field_beaches_continent[$updatenode->language][0]['value']=$values['continent'];
    $updatenode->field_country[$updatenode->language][0]['value']=$values['country'];
    $updatenode->field_about_location[$updatenode->language][0]['value']=$values['description_location'];
    $updatenode->field_travelling_location[$updatenode->language][0]['value']=$values['travelling_details'];
    $updatenode->field_location_facilities[$updatenode->language][0]['value']=$values['location_facilities'];
    $updatenode->field_beach_tag[$updatenode->language][0]['value']=$values['tags'];
    $updatenode->field_longtitude[$updatenode->language][0]['value']=$values['longtitude'];
    $updatenode->field_latitude[$updatenode->language][0]['value']=$values['latitude'];        
    foreach ($images as $image) {
    $file = file_load($image);
    $file->status = FILE_STATUS_PERMANENT;
    $updatenode->field_beaches_images[$updatenode->language][]['value'] = $file->fid;
    file_save($file);
    }
    node_object_prepare($updatenode);
node_save($updatenode);
   }        
$form_state['redirect'] = 'beaches/' . $clid;

I want to store multiple images fid in the field "field_beaches_images[$node->language][0]['value']" I have ten images, one image is mandatory user can upload up to 9 images. The problem is if any of the image field is empty, it does not store the other values,the node itself not creating. How can we achieve this (ie) the user can insert 1,2,...9 images. Assume if the user enters only 4 images, then the node itself is not created and generating error.

I'm facing a issue on this. I can able to add the images, but it does not supports updation. I have added the code used for editing the form.

For background read Why is hook_form_alter() so messy?, but essentially you want something like

foreach ($images as $image) {
  $file = file_load($image);
  $file->status = FILE_STATUS_PERMANENT;
  $node->field_beaches_images[$node->language][]['value'] = $file->fid;
  file_save($file);
}
