Ajax with markup regions

Recommended Posts

Hello. I have recently adopted PW markup regions and really like this way of working. However, I am also trying to learn how to use Ajax and I am not sure of a good way to use the two together. Has anyone got any experience, tips or hints on using them together? For ajax -  I've used a simple scheme where I have a "webservice" template and page that handles Ajax requests and returns the appropriate content wrapped with some markup for the requesting page. I have markup regions enabled and all my pages (bar webservice) include a _main.php which brings in the headers, a default body and the footer. My javascript intercepts the page links and does my ajax call to webservice and that sends back the appropriate markup which is then placed by in the div #body defined in _main.php.  Does this seem a reasonable way to work? I guess I am looking for some advice before I invest too much time going the wrong way!

Any guidance, remarks,  comments, or a nudge in the right direction greatly appreciated.

So far I found that using if(!$config->ajax): in my _main.php around head and foot parts and having a div targetted by Javascript as is commonly used - but in the case of an Ajax call I use wireRenderFile() to load markup from a file containing just the markup I need seems to work.... but I'm still playing with this.

For not so complex ajaxified pages this is what I do. Something like:

<?php
if ($config->ajax) {
	echo wireRenderFile("./rendered-ajax-call-result.php", array('page' => $page));
	return $this->halt();
}

Page is the only variable passed to the template partial and if something else is needed I make sure it is already part of page so that I can access it in the partial. The halt method is the recommended way so that ProcessWire can tidy up before exiting the process.

      Hi,
      I'm really struggling with this as it's something not in my wheelhouse. I'm creating a blog style page (a grid of cards) which has attributes.
      I have a snip of javascript which grabs values from checkboxes which are put into a value like the below:
      ?content=static_video&channel=facebook-ads_instagram-ads
      document.querySelector("form").onsubmit=ev=>{ ev.preventDefault(); let o={}; ev.target.querySelectorAll("[name]:checked").forEach(el=>{ (o[el.name]=o[el.name]||[]).push(el.value)}) console.log(location.pathname+"?"+ Object.entries(o).map(([v,f])=> v+"="+f.join("_")).join("&") ); document.location.href = location.pathname+"?"+ Object.entries(o).map(([v,f])=> v+"="+f.join("_")).join("&"); } As I'm currently refeshing the page on button click with those values the end result includes the location but can easily remove this.
      I then use this value in "input->get" to get the values which I then append to a find() rule. See code below:
      $selector = "template='adbank_pages',sort=published,include=all,status!=hidden"; // Get the channel and content inputs $channel = $input->get->channel; $content = $input->get->content; if($channel){ // Grab the channel string, explode into an array for checkbox checking and then replace _ with | to create or rules in the selector. $chanArray = explode("_", $channel); $chan = $channel = str_replace('_', '|', $channel); $selector = $selector .= ",ab_channels=$chan"; } if($content){ // Grab the content string, explode into an array for checkbox checking and then replace _ with | to create or rules in the selector. $contArray = explode("_", $content); $cont = $content = str_replace('_', '|', $content); $selector = $selector .= ",ab_content=$cont"; } if($input->get){ // If a valid input result $all = $pages->find($selector); } }else{ // If no input show them all $all = $page->children("template='adbank_pages',sort=-published,include=all,status!=hidden"); } $items = $all->find("limit=12"); // Limit the output and use pagination As mentioned above I currently refresh the page to adjust the $selector filter within the $all with a fallback $all if there are no results.
      I know I need to use AJAX to filter the content without refresh but I am really struggling with the set up. I have read multiple posts including the original by Ryan but still confused.
      If anyone can direct/help on this it would be appreciated.
      Thank you

      Hi 👋
      Anyone else having this problem?
      Requirements:
      - Repeater (matrix & normal) with mutlilanguage fields (text, textarea…) 
      - Backend language set to something other than default (ie. German) 
      Reproduce:
      - Add a new repeater Item (ajax, I found no way to possible to disable it with matrix)

      (Notice how the default language tab is active instead of the backend language…)
      - Write something into the (default language) field
      - Try to save, if field is required, this will not work. If not required, then when reloading, the content will be inside the backend language field, instead of the default language field who was (presumably) active
      Analysis:
      When  loading  a new repeater element with ajax, the default langue tab is active, but the backend language inputfield is visible (with no visual indication). When writing into the field, it will populate the backend language. When manually clicking on the default language tab (which is already active), the field will switch to the actual default language field (which is [now] empty) (that can now be populated…)
      Also Notice, the labels of the elements to be added are in default language as well instead of the translated label (images instead of Bilder)…
      ProcessWire 3.0.148, Profields 0.0.5…
      Is it my system configuration, or does anyone else have the same issue? This is a screen recording of the problem:

      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?

      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?
