programmatically save image to node with link in custom module

Question

Im quite new to drupal 7. But my approach is learning by doing. This have worked fine until now....

My problem is, that I in a custom module, with a form submit, save a node with all the filled fields, including images. (Code below)

My problem is that i want to add a, a href to the images i save, so when opening the node the images will link to the link i have saved.

Is this even possible?

My node_save with pictures is like this:

$who = $user->uid;
$test = 'term_id' . $who;
$test1 = 'sales_id' . $who;
variable_set($test, $base_url . '/Sales/' . $form_state['values']['sales_id_terms']);
variable_set($test1, $base_url . '/Sales/' . $form_state['values']['sales_id_comp']);

$term_id = $form_state['values']['sales_id_terms'];
$file_temp_top = file_load($user->top_banner);
$file_temp_bund = file_load($user->bund_banner);
$file_temp_power = file_load(110);

//$file_temp_top = file_save_data($file_temp_top, 'public://firm_images/', FILE_EXISTS_REPLACE);

$node1 = new stdClass();  // Create a new node object
$node1->type = 'product_link';  // Content type
$node1->language = LANGUAGE_NONE;  // Or e.g. 'en' if locale is enabled
$node1 = node_submit($node1);
node_object_prepare($node1);  //Set some default values
$node1->status = 1;   // (1 or 0): published or unpublished
$node1->promote = 0;  // (1 or 0): promoted to front page or not
$node1->sticky = 0;  // (1 or 0): sticky at top of lists or not
$node1->comment = 1;  // 2 = comments open, 1 = comments closed, 0 = comments hidden


$node1->title = $form_state['values']['sales_name'] . '_1';
$node1->field_betingelser['und'][0]['value'] = $terms;
$node1->field_top_banner['und'][0] = array(
                'fid' => $file_temp_top->fid,
                'filename' => $file_temp_top->filename,
                'filemime' => $file_temp_top->filemime,
                'uri' => $file_temp_top->uri,
                'status' => 1,
                'display' => 1,
);
$node1->field_bund_banner['und'][0] = array(
                'fid' => $file_temp_bund->fid,
                'filename' => $file_temp_bund->filename,
                'filemime' => $file_temp_bund->filemime,
                'uid' => 1,
                'uri' => $file_temp_bund->uri,
                'status' => 1,
                'display' => 1,
);
$node1->field_powerd_by['und'][0] = array(
                'fid' => $file_temp_power->fid,
                'filename' => $file_temp_power->filename,
                'filemime' => $file_temp_power->filemime,
                'uid' => 1,
                'uri' => $file_temp_power->uri,
                'status' => 1,
                'display' => 1,
                'href' => $GLOBALS['root_url'] . '/new-products/',
);
$node1->field_terms_id['und'][0]['value'] = $form_state['values']['kon_id_terms'];

// Add author of the node
$node1->uid = $user->uid;

// Set created date
$node1->date = 'complaint_post_date';
$node1->created = strtotime('complaint_post_date');

$new_path = 'sales/' . $node1->field_terms_id['und'][0]['value'];
$node1->path = array('alias' => $new_path);

// Save the node
node_save($node1);

Answer 1

I'm assuming the content type you're saving is currently using the included Image field. This field does not allow you to include a url that the image links to (it does allow you to link to the image itself or the content that it belongs to).

Answering your question directly, it sure is (and there's many ways)!

You can use the module linkimagefield. I think this one is closest to what you're asking. It adds a field type that includes a url that the image can then link to.

However, if the url the image links to is to be used in other places too, then the module image_link_formatter might be better suited for the task. With this module, you would add a Link field to your content type (that can be shown by itself or hidden), and set up the image field's display (admin/structure/types/manage/[node_type]/display) to use the link field as the target.

The file field will handle the display of the file regarding to its settings in the FieldUI.

So referencing the fid is sufficient:

$node1->field_top_banner['und'][0]['fid'] = $file_temp_top->fid;
