      I just wanted to share that I added an AJAX-powered gallery to an artist website that I developed and host: https://jackpinecreations.com/gallery/

      There were two things that frustrated me about creating this. Perhaps you can show me a better way.
      1. After creating my processing script, which I placed under /templates/scripts/get-items.php, I realized that I would get a 403, due to ProcessWire's routing and security. This forced me to have to create a template and page for this little script. This was frustrating simply because it seemed unnecessarily confusing. But worse, see #2.
      2. I usually use config.php to prepend and append each of my templates with a head.inc and foot.inc, which keeps my templates easy to use and I don't have to go and use the GUI to do so on each template separately. However, since I realized I needed to create a new template and page so as to access it, whenever I sent POST params to it, I would get the header and footer along with it!!! I could find no workarounds and had to remove the pre/append calls in config.php and use the GUI on each template individually.  
      Code Below if you're interested:
      HTML and JavaScript (forgive my sad JavaScript skills, I know this can be tightened up)
      <!-- Begin Grid --> <div class="container mt-4"> <div id="gallery" class="row"> <?php foreach ($page->children("limit=9") as $child): ?> <div class="col-6 col-md-4 gallery-item"> <a href="<?= $child->url ?>" title="View <?= $child->title ?>"> <img class="gallery-item" src="<?= $child->item_featured_image->size(640, 640)->url ?>" alt="<?= $child->title ?> Image"> </a> </div> <?php endforeach; ?> </div> </div> <!-- End Grid --> <div class="center-block text-center"> <button id="get-more-items" type="button" name="get-more-items" class="btn-vintage">Load More</button> </div> <script type="text/javascript"> var buttonGetItems = document.getElementById("get-more-items"); var indexStart = 0; buttonGetItems.addEventListener("click", function() { indexStart += 9; $.ajax({ url: '<?= $pages->get(1186)->url ?>', type: "POST", dataType:'json', // add json datatype to get json data: ({page_id: <?= $page->id ?>, index_start: indexStart}), success: function(data){ console.log(data); if (data[1]) { //for each element, append it. $.each(data, function(key, value) { $("#gallery").append(value); }); } else { $("#get-more-items").after('<p class="center-block text-center">There are no more items to load.</p>'); $("#get-more-items").remove(); } } }); }); </script> Processing Script
      <?php $items_array = []; $i = 0; foreach ($pages->get($input->post->page_id)->children->slice($input->post->index_start, 9) as $child) { $i++; $items_array[$i] = "<div class='col-6 col-md-4 gallery-item'> <a href='$child->url' title='View $child->title'> <img src='{$child->item_featured_image->size(640,640)->url}' alt='$child->title Image'> </a> </div>"; } echo json_encode($items_array); I love ProcessWire for hundreds of reasons, but I've been using AJAX more and more, and I'm not liking having to create templates to access scripts. 
      Any advice?

      Hello,
      I'm facing a weird issue here. I have a page loaded with this code inside (my comments in line ends) :

      if ($session->allPlayers) { // Set in a head.inc file. I have also a $session->set('allTeams', $allTeams); in my head.inc   $allPlayers = $session->allPlayers; } else {   $allPlayers = getAllPlayers($user, false);   $session->set('allPlayers', $allPlayers); } bd($session->getAll()); // HERE, I get a number of 11 variables which is what I expect In the same page, I have a link pointing to ajaxContent.php that loads stuff via Ajax.
      I just write this in my ajaxContent.php to test :

      bd($session->getAll()); // HERE, I get only 9 variables. All my newly set $session variables ($allTeams and $allPlayers) are not conveyed to ajaxContent.php ??? Would you have any idea why is that ??? Another thing : I have a $session->headMenu set in my head.inc, and this one works fine. I can retrieve it in my ajaxContent.php page.
      I've tried cleaning all caches but it doesn't change anything 😞 
      At first, I expected it to be a 15-minute update to my site... It turns out to be a 2-hour issue and I'm still  stuck.
      Thanks for your ideas !

      So I have a template called "development" where I am testing out a few ideas etc set up on a local mamp server. I also have a page called "ajax" using a template called ajax. From my development template, I am posting a form using ajax and all is working quite well:
      $('.test').click(function(event) { event.preventDefault(); redirectUrl = $(this).data('redirect'); var data = { firstName: $("#firstname").val(), lastName: $("#lastname").val(), email: $("#email").val(), phone: $("#phone").val(), redirectUrl: redirectUrl }; $.ajax({ type: "POST", url: "localhost:8888/sandbox/ajax/form/", data: data, success: function() { console.log(this.data); top.window.location = redirectUrl; }, failure: function() { console.log(this.data); } }); And in my ajax template:
      if($input->urlSegment == 'form'){ if ($_POST) { //handle the post } } The redirectUrl is a data attribute I added in to the button (that launches the form in a modal) that pulls in from a field in processwire. Everything works just fine locally, but when I export everything to a live site it fails. It will work 1 time and redirect, but if you go back to resubmit, it submits the data but won't redirect. Can anyone see any glaring issue here, or have a better way around this?
      ------------------------------
      So, it turns out the request to /ajax/form/ was being canceled. It still handled the POST request, but never sent back a 200 to show "success". Adding in 
      return false; at the end of my .onclick solved the issue. It is strange though as I have never had this issue before.

      Hello everyone,
      hopefully this is the right place to ask and is not a duplicate question.
      I'm pretty new to processwire, so... if this question is kind of funny for some of you, you're welcome 😄 
      I have the following issue and can't find anything understandable about it. Maybe I'm searching the wrong way, but anyways.. here is my question:

      How is it possible to rewrite the URLs, that I'll get a *.php ending?
      Example:
      https://www.mysite.de/urlsegment/ -> https://www.mysite.de/urlsegment.php
      https://www.mysite.de/urlsegment/urlsegment/ -> https://www.mysite.de/urlsegment/urlsegment.php
      Because I've read a lot about "Why do you wanna do this or have that?" – here my answer for that in advance:
      I've built a processwire installation inside or around an existing website. Therefore, we want to keep the existing *.php Google entries. Sure, we could redirect via 301 Redirect, but would prefer to keep the *.php ending.
      If you have further questions, please do not hesitate to ask.
      Thank you in advance for your help.

      Best regards

      Hi Guys
      How can I make a redirect inside the .htaccess to my custom maintenance.html file when any URL of my Website is accessed except the processwire admin (www.example.com/processwire/).
      Because I want that my User's still can access the website when they are loggedin in Processwire.
      When the current url starts with /processwire or if there is a processwire-login-cookie (Is there a cookie when user is logged in Processwire?) available the redirect should not work. Otherwise it should work.
      How can I achieve this?
