Hi, Looking to create form elements on a page–some input with a colection of form inputs and the appropriate labels and variables for that input. I've used ProForms in the past and rolled out my own when creating simply one off forms, but I wonder if anyone has found a good way of allowing form creation on page editing so that clients can adhocly make and edit forms?
Thanks

Hi all
Continuing my first project where I am creating and manipulating stuff from the frontend. Till now I've always added things like images from the backend, but in this project I need to add and move images from a frontend control. This is a photo album where images are stored in albums, each album being a page containing a Pageimages array in the usual way. So what I want to know is how do I move an image from one album (page) to another in the frontend? I just need some guidance on how to approach this. I suppose I need to do a copy and delete - but how do I copy an image or images from one page to another? What function should I use to create a new image on an existing page? I include a code snippet from the server side of my delete image request and it works fine. I'd like to implement something similar for a move and upload new image request.
Many thanks for any help. Paul
<?php namespace ProcessWire; // sanitize inputs as 1-line text $action = $sanitizer->text($input->post('action')); $instr = $sanitizer->text($input->post('input')); $sel = $input->post('selected'); // Expect JSON for image selected image list $selected = json_decode($sel); $nosel = count($selected); $response = array(); // for building JSON response switch($action) { // delete selected images case 'delete': $out = "<p>Deleted $nosel image(s)</p>"; foreach($selected as $item){ $album = $pages->get($item->album); $album->of(false); $out .= "<p>Image {$item->file} from album {$album->title}</p>"; $album->images->delete($item->file); $album->of(true); } $out .= saveUpdatedAlbums($pages, $selected); // add the response message for the delete $response['message'] = $out; break; ...... // save any album that had an image deleted function saveUpdatedAlbums($pages, $selected) { $cur = ''; $out = ''; foreach($selected as $item){ $album = $pages->get($item->album); if($album->id != $cur) { $album->of(false); $album->save('images'); $album->of(true); $cur = $album->id; $out .= "<p>Updated album {$pages->get($cur)->title}</p>"; } } return $out; }

Inspired by a recent question.
Image Crop Ratios
Allows preset aspect ratios to be defined per image field for the ProcessWire image crop tool.
The module adds a select dropdown to the crop tool. Choose an aspect ratio and the crop area will be fixed to that ratio.
Screencast
Installation
Install the Image Crop Ratios module.
Configuration
Default aspect ratios for all image fields can be defined in the module config. Aspect ratios for specific image fields can be defined on the Input tab of the field settings. You can override the ratio settings in template context if needed. Insert a hyphen as the first item in the ratio settings unless you want to force a ratio to be applied to the crop tool. The hyphen represents a blank option that allows a free crop area to be drawn. Usage
Click the "Crop" link on the details view of an image thumbnail. Click the "Crop" icon at the top of the editor window. Choose an option from the "Ratio" select dropdown.

Bit of a newbie type question, even though I've been using PW for quite a while, I've not had to manipulate assets from the front end before. I now have a need to update image properties from the front end and I'm trying to update an image description and tags when clicking on a link. I get the selected image and for example I can delete it with the code below. But I am missing some basic understanding when updating image description field as nothing happens, no errors but the description field remains empty. Any idea what steps I am missing? Many thanks.
// how to update image description? $al = $pages->get($album); $pgfile = $al->images->getFile($file); $al->of(false); $pgfile->description = "Test description"; $al->save(); // to delete an image - this works $al->of(false); $al->images->delete($file); $al->save();
