Lost in Pageimages or How to add a file to an existing Imageinputfield

[felixthecat]

Hello,

What is the correct way to add an manually created file to an existing imagefield. The new created file is in the same Folder where the page stores the files.

Here what i tried. Runs without errors but doesnt add the file to the imagefield:
 

// image_ok.jpg is the file which is stored in the imagefield
// image_new.jpg is the manually created file and should be added to the imagefield of image_ok.jpg

$pagefiles = $imageOK->pagefiles;
$pagefiles->add('image_new.jpg' );
$page = $imageOK->page;
$page->of(false);
$page->save($pagefiles->name);

What is wrong?

Thanks.

If you don't already know the page and field name that $imageOK belongs to and have to work it out from the Pageimage then I suggest:

$p = $imageOK->page;
$field_name = $imageOK->field->name;
$p->of(false);
$p->$field_name->add('/full/disk/path/to/image_new.jpg');
$p->save($field_name);

Here is the description of Pageimages class

ProcessWire Pageimages

Pageimages are a collection of Pageimage objects.

Typically a Pageimages object will be associated with a specific field attached to a Page. 
There may be multiple instances of Pageimages attached to a given Page (depending on what fields are in it's fieldgroup).
