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;

      These issues should be fairly easy for any intermediate to advanced ProcessWire developer to answer. I'm new to PHP and relatively new to ProcessWire and just need a bit of help. What I'm trying to do is bring in a couple of cards from my Projects page to display on my home page. I finally got the code right to bring in the cards but right now they're using my original images instead of my resized "variations". So firstly, I would like to know how to reference the variations of my images instead of using the original. Secondly, I need to grab only four of the cards from the Project page and not import in all ten. It should be just two small changes to my code to do these things (I would imagine). Here is the code I currently have for that section:
      <?php // https://processwire.com/api/arrays/ // check if the array of images has items if (count($pages->get("/projects/")->images)) : // get array of images from the field $images = $pages->get("/projects/")->images; $count = 0; // iterate over each one foreach ($images as $image) : $count++; $sectionText = $pages->get("/projects/")->get("paragraph_$count"); $img = $image; $buttonCode = $pages->get("/projects/")->get("url_$count"); ?> <span id="card<?php echo $count?>" class="card"> <img class="cardThumb" src="<?php echo $img->url; ?>" alt="<?php echo $image->description; ?> Thumbnail" /> <div class="cardBody"> <div class="cardText"> <h2><?php echo $img->description; ?></h2> <?php echo $sectionText; ?> </div> <div class="primaryBtn"> <a href="https://www.paypal.com/donate?hosted_button_id= <?php echo $buttonCode; ?> &source=url"> <button> <i class="fas fa-donate"></i> Donate </button> </a> </div> </div> </span> <?php endforeach; endif; ?> Thanks in advance for any help!

      Hi,
      When I upload a large(ish) SVG (≈120ko in this case) into an image field, it tends to get stuck at 100% and block the whole website. If I force refresh the admin page, the svg has not been uploaded. The file is correctly copied into the assets folder though. Other svg tends to be uploaded fine albeit I've noticed that pages containing svg images in the admin are very slow to load generally. Other pages using the same template but with jpeg or png images are much faster to load.
      I get the following error in the JS console:

      I develop locally using MAMP on macOS and I'm using Firefox. I'm using the last ProcessWire version (3.0.165).
      I also tested in Chrome and got the same error.

      Hello everyone!
      I am new to PW and at this moment there are these issues that I cannot clearly understand:
      1) Image Position
      Previously I used TinyMCE and there I could get an image floating left or right by simply selecting it and pressing the text justify buttons from the menu bar. In CKEditor however it just causes the hole paragraphs content to be aligned which results in code like this and of course the image is not floating that way:
      <p class="xyz" style="text-align:right"><img alt="" src="someimage.jpg" width="1000" /></p> Q: Is it possible to add float to images just by clicking the text align buttons? As far as I figured it out the only way to align images is within the image dialouge which I find is pretty inconvenient.
      2) Image Caption / Figure / Figcaption
      When a title is given to an image it is wrapped inside a figure tag and a figcaption tag is applied. That's fine. But I need the image to be wrapped inside another picture tag for styling reasons (I want to add a shadow png with picture::after). I'd like to end up with this:
      <figure><picture><img alt="" src="someimage.jpg" width="1000" /></picture> <figcaption>Caption there</figcaption> </figure> Q: I think I have to modify the plugins code to achieve it, right? If so does anyone knows the file / location?
      Q: If a figure tag is placed how would I change its position say to another paragraph? Drag & drop just relocates the image leaving the figure tag where it was. How to reposition the whole thing?
      Q: How / where would I enter image description the be shown only in say a lightbox but not alongside the image itself? I thought the textarea provided in the image field could do the job but how to access it from the editor? Even possible?
      Well I hope someone understands and I'd be thankful for a clue of any of these questions.
      ✌️ Bike
