  1. Just to confirm the WireCache worked a treat for my drop list. Many thanks.
  2. Thank you Zeka and horst. I will try the $config->adminThumbOptions that you suggested horst. I am using proportional thumbnails and I note it's now deprecated in admin. I set a fixed height and calculate a scaling factor for proportional width as in the function below. It seems to work ok but I'm not sure it's the best way to tackle this. function getScaledThumbNail($image) { $justHt = wire('pages')->get('/')->gal_just_row_height; $scale = $image->height / $justHt; if($scale <= 0) { $thumb = null; }else { $tnW = $image->width / $scale; $thumb = $image->size($tnW, $justHt); } return $thumb; }
  3. Hi to everyone. I have created an online photo album using PW and I have a front end implementation to upload images into my albums. The problem I encounter is if / when I log in to the backend and view any album there are potentially several thousand images in each album and PW then generates it's default image thumbnails which effectively times out my request and also generates thousands of unwanted thumbnails. How can I tweak things so these do not get created? Just wondered if it's possible to change this default behaviour. Many thanks
  4. I just tried your site and it loaded very quickly it didn't seem slow at all.
  5. Hi @Zeka thanks for the idea of using WireCache. It does seem suitable for my needs so I'll give that a try. Many thanks!
  6. I've been working on making an online photo gallery for some time now and I have it working well using ProcessWire for storage and indexing of my images. Basically I have a series of albums represented by pages using my album template and this contains a images collection (usual Pageimages). I'm using the tags feature to tag the images so I can search across all the albums for a subject of interest to see all images for any tag in one view. This work well, and when I initialise I scan all images and build a list of all tags with the number of images with each tag and populate a drop down list with this info. so a user can select a tag from the list and see just the tag of interest. So far so good, but as I now have around 8000 images in the database the initial scanning does take a few seconds. It occurred to me that once this scan is done, it would be better to store this info on disc as this data will only change infrequently and only need rescanning if a tag is changed (such as an image is deleted or added). My question is how should I store this info? For example should I use an XML file? Or perhaps JSON? I could check for this file at start up and simply load that data into my drop list which would speed up start up. But I wondered if I could keep this list in a PW field somewhere. It's basically just a text list, but it does not seem obvious to me how to best store this in PW. Any ideas on how one would tackle this would be very interesting to me.... Thanks!
  7. 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;
  8. 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; }
  9. I confirm that this works - when I called trackChange before save the change to the image description field was savedA. Thanks again Horst. As a footnote, when updating tags I found that I can use $image->addTag('foo,bar,baz') without trackChange and tags were saved because it's a dedicated function to add tags. Regards
  10. Thanks Horst. My file basename is correct as I am able to echo out all the properties of the image, but I did not know about trackChange perhaps that is the missing bit. $pgfile = $al->images->getFile($file); if($pgfile) { echo "basename => $pgfile->basename \n"; echo "description => $pgfile->description \n"; echo "ext => $pgfile->ext \n"; echo "filename => $pgfile->filename \n"; echo "filesize => $pgfile->filesize \n"; echo "filesizeStr => $pgfile->filesizeStr \n"; } The above echoes out all the properties as expected , but assigning description to something does not update it when I save page. I guess I'm only changing a local copy here and it's not "connected" to the page. I imagine the trackChange makes that happen. I will try it and report back. Many thanks
  11. 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();
  12. Thank you. That works! But I now realise I need to iterate each album to build a list of tagged images matching. I wonder if there is a sub selector that can do that? Thanks again I can get on with it now 🙂
  13. Hi I have a number of pages with images and I'm having a problem selecting on the image descriptions. In the code snippet below, the I added images.description field to my selector and it does work in that I get the expected no. of matches. So findTag gets me a list of images matching the tags in the code, but if I swap that line for the commented line $match->images->find it does not work giving 0 results. There is findTag for tags but for description there is not a dedicated function, so I should use find. But what selector will give me a list of images matched by image description? Many thanks. if($q !== '') { $keywords = $sanitizer->selectorValue($q); $matches = $pages->find("template=album, title|summary|images.tags|images.description~=$keywords"); echo "<p>match count: $matches->count</p>"; foreach($matches as $match){ echo "<p>{$match->title}</p>"; $i = $match->images->findTag($keywords); //$i = $match->images->find("template=album, images.description~=$keywords"); GIVES ZERO MATCHES $j = count($i); echo "<p>No. of image matching: $j</p>"; foreach($i as $img){ echo "<img src='{$img->url}' alt='{$img->description}'>"; } } }
  14. Thanks Horst. I created a test file with echo phpinfo() and found in the core table output the following listed as disabled: disable_functions shell_exec ,exec, system, popen, set_time_limit this for both local and master value columns in the table. i note your comments about switching or upgrading host! Paul
  15. I had no luck with any of the above, in the _init or config.php it gave an error as it's disabled by the host and in .htaccess the site did not run it just displayed a config error. Fasthosts have replied to my question saying there is no option to use set _time_limit on shared hosting. (see below) As a workaround I have commented out the set_time_limit call in the core and it works ok - for now...
