Not enough memory to load/resize

[martind]

no problem, your suggestion to do it by a new inputfield-file variant works perfect, i have a multiple-file field now, that executes the imagick scaling after upload und shows the generated thumbnail in the file-list. pretty good for the first step, as i think.

[martind]

is it possible, to add one of the generated images from the new file-field to an existing image-field on the same template?

[LostKobrakai]

Sure.

$page->imageField->add($path);

[martind]

Sure.

$page->imageField->add($path);

Thank you kobrakai,

i`ve problems to get the $page varible in my inputfield module. i'm not really familiar with modules in general, so maybe i don`t understand someting common here.

Depends on which hook you're using, if you're using hooks. 

[martind]

no. i've cloned the inputfield-file module to InputfieldFileApp.module (and copied FieldtypeFile.module as FieldtypeFileApp.module inside the folder). The new filefield works, i can use some custom functions inside, this is good. But now, i want to copy a specific version of a new uploaded file to another field, an image field on the same template.

inside InputfieldFileApp.module wire('page') is the edit page, not the page the field is on. thats logical, but doesn't help me out.

... in this post the behavour got discussed, but i cant get ryans solution to work.

It would be more "update-prove" to just hook the existing modules and add in your needed function on runtime, but this works, too. Most inputfields work independent on any page context, like the file field. Therefore the Fieldtype does add some hooks to dynamically inject this information, to cater for changing uploadPaths (see setupHook). You could edit the called function to not only inject the path, but also the $page object into the inputfield.

ok, thank, that helped, declaring $inputfield->editPage = $page; in the Fieldtypes hookProcessInput function i have the page-object in the inputfield module.

inside the ProcessInput function i create my image variants and with

$this->editPage->app_img->add($this->destinationPath.$filename."-app-web.jpg");
$this->editPage->save();

... i can copy the image to the app_img field in the background and it appears when saving the page. Is it possible to actualize the image-field after the add() is done?

[LostKobrakai]

That's not easily possible as the server cannot tell the client that there's a new image without the client actually requesting data from the server. You'd need to change the javascript of the image field to do some kind of server polling and requesting new images.

[martind]

ok, thats something i can live with, thank you.

another question: when using something like $this->message($this->_("blabla...")); in the inputfield module we spoke about, shouldn`t this work?

[LostKobrakai]

Depends on where you're doing this and if you're using SystemNotifications. With the module enabled I had times, where messages invoked shortly before a redirect where gone after the redirect.
