add and move image from frontend

Recommended Posts

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;
}

SOLVED. As usual with processwire it's very easy. I just needed to do use add() function to add a copy to the album and then delete the relocated image. In the code below $instr contains the album name for destination album.

 

case 'move':	
		// Move image(s) from one album to another
		$out = "<p>Move $nosel images(s) to album $instr</p>";
		$newalb = $pages->get("/{$instr}/");
		$newalb->of(false);
		
		foreach($selected as $item){
			$album = $pages->get($item->album);
			$album->of(false);
			$image = $album->images->getFile($item->file);	
			$basename = $image->basename;	
			$filename = $image->filename();
			$out .= "<p>{$basename} in {$album->title}</p>";
			$newalb->images->add($filename);
			// delete the relocated image			
			$album->images->delete($image);			
		}					
		
		$newalb->save('images');
		$newalb->of(true);	
		
		$out .= saveUpdatedAlbums($pages, $selected);			
		$out .= "<p>Updated album $newalb->title</p>";
		
		$response['message'] = $out;
	break;

      Hi,
      I have a repeater with some images in it.
      As Superuser I can work with the Actions (rotate...). But my Users with lower Rights can't use this Actions.
      The same User can use the Actions on images outsite a Repeter-Field. So I think it's not a Problem of Rights-Management but from Images in Repeater Fields.
      ProcessWire 3.0.164.  Bug? Or can I manage this in the settings?
      Thanks in advance

      BETA: SplashAndGrab
      https://github.com/madebymats/InputfieldSplashAndGrab
      This module attaches a search input to selected image fields that lets you search and download images from Unsplash.
      (Unsplash is a stock photo service where you can download images for free and use as you wish. No strings attached.)   
      You can search by string, colors, orientation/crop and order by relevance or time published
      I find Unsplash useful both for placeholder images when building sites but also as a time saver for editors if they don’t have any images at hand, just search, download and publish.

      Thanks to @apeisa for building the  FlickrInputField Module and @Robin S for AddImageUrls,  took a lot ideas and code from those modules.

      We have created a module to create BlurHash strings for images while uploading in ProcessWire. This blurry images will be saved in the database because they are very small (20-30 characters) and can be used for Data-URL's  as placeholders for image-lazy loading.
      https://github.com/blue-tomato/ImageBlurhash
      E.g. where we use this in production:

      Hello dear PW gurus.

      I have stumbled over a strange error that i all of sudden got when trying to upload an image to a images field on a page.
      There where images allready stored in the field that i wanted to keep, but during the upload the error apear and after that all images are gone from the field and i can´t upload any, i just get the error every time.
      I am running ProcessWire 3.0.153 dev.
      Update:
      After looking in the assets folder i find the folder for the page and the image files seems to be there including the ones i tried to upload when the error occured.
      But they don´t show up in the images field in the page editor.
       
      The error reported:
       
      SQLSTATE[01000]: Warning: 1265 Data truncated for column 'ratio' at row 1 And here is a screenshot of the event:

      The TracyDebugger Error reporting:

      I hope you fine folks could point me in a direction.
      But it seems our old pal set_time_limit() is back.

      Regards, EyeDentify

      I can't tell what's wrong; my local development version appears just fine, but I copy over the site files and db online and the homepage content is not being contained. This is what it should look like (same site in the same browser, running on my localhost): http://imgur.com/UFZFzrd
      What could be the problem here? Sorry to bring up something so irrelevant to PW here, I just know that you all are a valiant and helpful group, and no one on StackExchange seems to even know what I'm talking about.
      Thanks a lot.
