Use AJAX to get field content

Recommended Posts

I have been wanting to set up a quick "dashboard" for a recent project, and was considering using ajax to get a "real time" update/refresh on the page (some of my output depends on the datetime field). I know how to get the desired output using php with some if statements comparing todays date to the date stored in the field, however, I am a bit at a lose of how to interact with the ProcessWire API using ajax to get the desired effect. I found the following 

 

and know that I need to start off with: 

<?php
if($config->ajax) {
    // page was requested from ajax
}

Unfortunately, as I mentioned earlier, how would one actual find pages using a template and get the field contents from them using AJAX? I apologize if this seems bit broad, but I am stil getting a grasp of using AJAX to deliver content to get a real time update on a page without refresh.

AJAX or normal request doesn't really matter to backend. You just detect if request is an AJAX request and act accordingly.

Because I had some things to do, I decided to procrastinate by building a simple module and write a tutorial for it.

      Hey folks,
      for a module (a pagebuilder based on PageTable) I need to save some settings as JSON. The values are saved for each page table item (a pw page). It's working well, but I am looking for ways to improve the structure I have. As I'm not that experienced with JSON, maybe someone more experienced can take a look and tell me if my approach is good practice. 

      My goal is to make all the items accessible by page id, without looping over them (using objects instead of arrays):
      // access from template with pw page var $jsonObject->items->{$page}->cssClass; Her is an example of my JSON structure:
      { "items": { "3252": { "id": "3252", "cssClass": "pgrid-main", "breakpoints": { "base": { "css": { "grid-column-end": "auto", "grid-row-end": "auto", "grid-column-start": "auto", "grid-row-start": "auto", "align-self": "auto", "z-index": "auto", "padding-left": "60px", "padding-right": "60px", "padding-top": "60px", "padding-bottom": "60px", "background-color": "rgb(255, 255, 255)", "color": "rgb(0, 0, 0)" }, "size": "@media (min-width: 576px)", "name": "base" } } }, "3686": { "id": "3686", "cssClass": "test_global", "breakpoints": { "base": { "css": { "grid-column-end": "-1", "grid-row-end": "span 1", "grid-column-start": "1", "grid-row-start": "auto", "align-self": "auto", "z-index": "auto", "padding-left": "0px", "padding-right": "0px", "padding-top": "0px", "padding-bottom": "0px", "background-color": "rgba(0, 0, 0, 0)", "color": "rgb(0, 0, 0)" }, "size": "@media (min-width: 576px)", "name": "base" } } }, "3687": { "id": "3687", "cssClass": "block_editor-3687", "breakpoints": { "base": { "css": { "grid-column-end": "span 2", "grid-row-end": "span 1", "grid-column-start": "auto", "grid-row-start": "auto", "align-self": "auto", "z-index": "auto", "padding-left": "0px", "padding-right": "0px", "padding-top": "0px", "padding-bottom": "0px", "background-color": "rgba(0, 0, 0, 0)", "color": "rgb(0, 0, 0)" }, "size": "@media (min-width: 576px)", "name": "base" } } }, "3696": { "id": "3696", "cssClass": "block_editor-3696", "breakpoints": { "base": { "css": { "grid-column-end": "span 2", "grid-row-end": "span 1", "grid-column-start": "auto", "grid-row-start": "auto", "align-self": "auto", "z-index": "auto", "padding-left": "0px", "padding-right": "0px", "padding-top": "0px", "padding-bottom": "0px", "background-color": "rgba(0, 0, 0, 0)", "color": "rgb(0, 0, 0)" }, "size": "@media (min-width: 576px)", "name": "base" } } } }, "breakpointActive": "base", "breakpointActiveSize": "@media (min-width: 576px)" }

      ProcessWire Dashboard

      Download
      You can find the latest release on Github.
      Documentation
      Check out the documentation to get started. This is where you'll find information about included panel types and configuration options.
      Custom Panels
      The goal was to make it simple to create custom panels. The easiest way to do that is to use the panel type template and have it render a file in your templates folder. This might be enough for 80% of all use cases. For anything more complex (FormBuilder submissions? Comments? Live chat?), you can add new panel types by creating modules that extend the DashboardPanel base class. Check out the documentation on custom panels or take a look at the HelloWorld panel to get started. I'm happy to merge any user-created modules into the main repo if they might be useful to more than a few people.
      Roadmap
      Panel types Google Analytics Draft At a glance / Page counter 404s  Layout options Render multiple tabs per panel Chart panel load chart data from JS file (currently passed as PHP array)

      Hi all
      I need to export all the texts from a website to a translation company (as json or csv or txt...). How can this be done? Of course manually, but this website is huge and it would take me years...
      Also, as a second step, importing the translation ...
      Any ideas anyone? Tutorials? Plugins?
      Thanks for your help.

      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:
      Issue: https://github.com/processwire/processwire-issues/issues/1179

      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?
