      Hello there,
      I am building my website, which has a dozen projects with 10 images each. Basically, I need a filtering system but built in the most efficient and user-friendly way. You can see below that the images flow sideways so being hidden, JS lazy loading was a good tool, but I just wanted to try AJAX. Is it fit for this purpose or it's more for dynamic content?

      Hi there,
      I am new to PW but already very convinced. I need to build a dropdown button to browse in a collection of authors by country and language. The dropdown should be editable in the BACK and displayed on the same as the authors collection. I tried my luck with "PageField Creator" but I don't know how to display the dropdown, I simply used: 
      "$content .=$page->Land;" (the name of the select field)
      but nothing is displayed...
      I see there is a 2nd module out there to achieve this : "Select Options Fieldtype". I am not sure what is the difference, anyone has a tip?
      And a clear tutorial with the necessary steps to build this? I am a bit confused which should be the parent template or page, if it should have a file or not...
      Thanks a lot in advance!

      👋 PW Pros…
      I have some hooks that I need to bind at the init phase (or even __construct) and I was wondering, and I couldn't find a good and simple way to determine if I'm in the admin. Would be nice if there is a reliable short option to do so, but I can't seem to find one… Is there a coherent way to tell this no matter where I am?
      Right now, I use the following method inside one of my modules:
      public function isAdmin($page = null) { if ( strpos($this->input->url, $this->urls->admin) !== false || $this->process instanceof ProcessPageList || $this->process instanceof ProcessPageEdit || ($page instanceof Page && $page->rootParent->id == $this->config->adminRootPageID) ) { return true; } return false; } @ryan wouldn't it be nice to have something like wire()->isAdmin(); like wire()->user->isLoggedin(); to tell if we are in admin – very early on (probably even in __construct() phase of modules?

      I have been messing around with creating pages from ajax requests, and it has gone swimmingly thus far. However, I am really struggling with creating a page and saving an image via ajax. 
      The form:
      <form action="./" role="form" method="post" enctype="multipart/form-data"> <div> <input type="text" id="preview" name="preview" placeholder="Image Title"> </div> <div> <input type="file" id="preview-name" name="preview-name"> </div> <div> <select id="select-tags" name="select-tags"> <?php $tags = $pages->find("template=tag"); ?> <option value="">Select Your Tags</option> <?php foreach ($tags as $tag) : ?> <option value="<?= $tag->name; ?>"><?= $tag->name; ?></option> <?php endforeach; ?> </select> </div> <div> <button type="button" id="submit-preview" name="submit" class="">Upload Images</button> </div> </form>  
      The ajax in my home template:
      $('#submit-preview').click(function(e) { e.preventDefault(); title = $("#preview").val(); image = $("input[name=preview-name]"); console.log(title); console.log(image); data = { title: title, image: image //not sure if this is actually needed }; $.ajax({ type: 'POST', data: data, url: '/development/upload-preview/', success: function(data) { console.log("Woo"); }, error: function(xhr, ajaxOptions, thrownError) { alert(xhr.responseText); } }); }); And finally in my ajax template:
      $imagePath = $config->paths->assets . "files/pdfs/"; //was from an older iteration $title = $sanitizer->text($_POST['title']); $image = $sanitizer->text($_POST['image']); $p = new Page(); $p->template = "preview"; $p->parent = $pages->get("/previews/"); $p->name = $title; $p->title = $title; $p->save(); $p->setOutputFormatting(false); $u = new WireUpload('preview_image'); $u->setMaxFiles(1); $u->setOverwrite(false); $u->setDestinationPath($p->preview_image->path()); $u->setValidExtensions(array('jpg', 'jpeg', 'gif', 'png', 'pdf')); foreach($u->execute() as $filename) { $p->preview_image->add($filename); } $p->save(); I can complete the file upload but just using a simple post to the same page and it it works well, but I was really trying to work out the ajax on this so I could utilize some modals for success on creation (and to keep my templates a little cleaner). When I do run the code I have, a new/blank folder is created under assets, and a new page is created with the correct title entered. However, no image is being processed. I do get a 200 status in my console. I have searched google for help, but everything seems to be slightly off from my needs. If anyone could help point me in the right direction I would greatly appreciate it.

      So I am using ajax to upload an image, but I am getting the error "Method WireUpload:: save does not exist or is not callable". I am not quite sure how to go about fixing this (at the moment).
      elseif($config->ajax && $input->urlSegment1 == "upload-preview") { $u = $config->paths->assets . "files/pdfs/"; $title = $sanitizer->text($_POST['title']); $p = new Page(); $p->template = "preview"; $p->parent = $pages->get("/previews/"); $p->name = $title; $p->title = $title; $p->save(); $p->setOutputFormatting(false); $u = new WireUpload('preview_image'); $u->setMaxFiles(1); $u->setOverwrite(false); $u->setDestinationPath($p->preview_image->path()); $u->setValidExtensions(array('jpg', 'jpeg', 'gif', 'png', 'pdf')); foreach($u->execute() as $filename) { $p->preview_image->add($filename); } $u->save(); } I compared my code to something I did previously (though previously I just posted to the current template file, not through ajax) which works, but this doesnt seem to be working. I have the _init.php file prepending as well. Does anyone have any ideas of what might be happening?
