160 Image Maximum?

Recommended Posts

I have an image gallery based on an Image field with about 300 images in it. That caused a little issues with uploading, since it's on a shared host I had to do that piecemeal in order to not overload the server. I kept refreshing the frontend of that page to make sure the server doesn't run out of memory compressing the images, as such an amount obviously requires thumbnails. After 160 images the frontend no longer updates. I can add images to the backend, but they are not shown on the frontend. The images field is not limited in any way. Is there a cap to the amount of images uploaded to a single field? Or any other aspect that might explain such behaviour?

The images show up fine in the backend, but when I foreach() through that field I only get 160 results. Any idea what might be going on?

If the server would have a classic timeout on a foreach() it wouldn't serve the page at all... but it does. I'll check the logs as soon as I have access again. Hosting company changed it's control panel... I'll check that module! It goes a bit against the intent of the application to be dependent on superuser actions, but at the very least I learn a few more tricks.

I also uploaded a bulk of images on the local server. This one behaves more natural. The first request I do times out due to trying to compress 303 images in a single request. When I do a second request, many images are already compressed so eventually it doesn't time out anymore. This is acceptable. It seems there's some artificial limit on the live server or something.

      Hello Dear PW Gurus.

      Hope you fair well in these Corona Crisis times.

      Anyhow, i have a problem with a Cryptic error message that shows up when i am trying to Delete images out of a Images field.
      The Error message does say a little but it does not make sense to me why i can´t delete the images because of it.

      Is it some permission issue perhaps?

      I will attach screenshots of it and what i did prior to it.
      I am from sweden so ignore the funny words here and there.

      Hope you all can send me on the right track.
      i am running PW 3.0.139 on this install.

      Step1:

      Step 2: Select the images with the trashcan symbol

       
      Step 3: Cryptic Error message

      I am scratching my head on this one, have not seen this before.

      Thankfull for all help.

      This short script loops through some images from an XML feed and pushes new ones to an image field. It all works perfectly, except for some reason the last image (only) in the loop each time doesn't receive the image description... can everyone spot why? TIA! 🙂 
      foreach ($propertyImages as $img) { $fileName = trim($img[0]); if ( !empty($fileName) ) { $imgPath = '../property_data/'.$fileName; if(file_exists($imgPath) && !in_array(strtolower($fileName),$currentImages)) { $p->property_images->add($imgPath); $p->save(); $newImg = $p->property_images->last(); $newImg->description = $img[1]; $p->save(); } } }

      Add Image URLs
      Allows images/files to be added to Image/File fields by pasting URLs.

      Usage
      Install the Add Image URLs module.
      A "Paste URLs" button will be added to all image and file fields. Use the button to show a textarea where URLs may be pasted, one per line. Images/files are added when the page is saved.

      Hello all,
      sharing my new module FieldtypeImageReference. It provides a configurable input field for choosing any type of image from selectable sources. Sources can be: 
      a predefined folder in site/templates/ and/or a  page (and optionally its children) and/or the page being edited and/or any page on the site CAUTION: this module is under development and not quite yet in a production-ready state. So please test it carefully.
      UPDATE: the new version v2.0.0 introduces a breaking change due to renaming the module. If you have an older version already installed, you need to uninstall it and install the latest master version.
      Module and full description can be found on github https://github.com/gebeer/FieldtypeImageReference
      Install from URL: https://github.com/gebeer/FieldtypeImageReference/archive/master.zip
      Read on for features and use cases.
      Features
      Images can be loaded from a folder inside site/templates/ or site/assets Images in that folder can be uploaded and deleted from within the inputfield Images can be loaded from other pages defined in the field settings Images can be organized into categories. Child pages of the main 'image source page' serve as categories mages can be loaded from any page on the site From the API side, images can be manipulated like native ProcessWire images (resizing, cropping etc.), even the images from a folder Image thumbnails are loaded into inputfield by ajax on demand Source images on other pages can be edited from within this field. Markup of SVG images can be rendered inline with `echo $image->svgcontent` Image names are fully searchable through the API $pages->find('fieldname.filename=xyz.png'); $pages->find('fieldname.filename%=xy.png'); Accidental image deletion is prevented. When you want to delete an image from one of the pages that hold your site-wide images, the module searches all pages that use that image. If any page contains a reference to the image you are trying to delete, deletion will be prevented. You will get an error message with links to help you edit those pages and remove references there before you can finally delete the image. This field type can be used with marcrura's Settings Factory module to store images on settings pages, which was not possible with other image field types When to use ?
      If you want to let editors choose an image from a set of images that is being used site-wide. Ideal for images that are being re-used across the site (e.g. icons, but not limited to that).
      Other than the native ProcessWire images field, the images here are not stored per page. Only references to images that live on other pages or inside a folder are stored. This has several advantages:
      one central place to organize images when images change, you only have to update them in one place. All references will be updated, too. (Provided the name of the image that has changed stays the same) Installation and setup instructions can be found on github.
      Here's how the input field looks like in the page editor:

      If you like to give it a try, I'm happy to hear your comments or suggestions for improvement. Install from URL: https://github.com/gebeer/FieldtypeImageReference/archive/master.zip
      Eventually this will go in the module directory, too. But it needs some more testing before I submit it. So I'd really appreciate your assistance.
      Thanks to all who contributed their feedback and suggestions which made this module what it is now.

      Hi. I've been using Processwire for a few years now and installed it on a few different shared hosting servers without issues, but I'm now running into an issue on a Fasthosts shared server that I've not seen before. The installation goes ok and I have a working default site profile but I am unable to complete any uploads of images. It just hangs at the progress spinner during the upload. I thought it might be a priviledge issue so have temporarily set the dir / file privs. as 777 / 666 just to test that but it made no difference. I have no errors in the wire log. In server error log I have:
      set_time_limit() has been disabled for security reasons in ....htdocs/wire/core/ImageSizerEngine.php on line 1035 and i note in the assets/file dir. where the image is being stored the date on the file being created has a year of 1970 and 0 length. If I leave the page this file disappears and nothing has been stored. 
      Does anyone know how I can enable set_time_limit if this is likely to be the problem? 
      Many thanks! Paul
