Module: Leaflet Map

[gebeer]

@mr-fan if you are still having the problem from 

with geocoding from your custom fields, maybe my modified InputfieldLeafletMapMarker.js gist can help. I have a custom button in the form that triggers the geocoding, defined on line 48 and a fucntion from line 135 that takes values from custom fields, concats them and does the geocoding.

[mr-fan]

Thanks i will test asap.

Thanks to netcarver - great addition!

I tried this on localhost with a new project. I getting errors in the backend and the map space is white.

Propbably because I am running the backend in https:

http://cdn.leafletjs.com/leaflet-0.7.3/leaflet.css - Works

https://cdn.leafletjs.com/leaflet-0.7.3/leaflet.css - Works not (Firefox security - Invalid certificate)

They advise a different CDN on their homepage, that's maybe why:

Using a Hosted Version of Leaflet

The latest stable Leaflet release is hosted on a CDN — to start using it straight away, place this in the head of your HTML code:

<link rel="stylesheet" href="https://npmcdn.com/leaflet@0.7.7/dist/leaflet.css" />
<script src="https://npmcdn.com/leaflet@0.7.7/dist/leaflet.js"></script>

or

Did anyone try with 1.0 latest rc? http://leafletjs.com/2016/07/16/leaflet-1.0-rc2.html

[netcarver]

@ceberlin Could you describe a little more about which version you are trying - Mats', gebeer's or the one I posted? I did have some trouble initially with getting the Leaflet related files in the right place. Having a script blocker running also broke things for me - once I enabled all JS on my local site things started working a lot better.

@Beluga I haven't tried that version - yet. Can't speak for Mats or gebeer. See below.

[netcarver]

@Beluga I just pushed a new leaflet-v1.0.0rc2 branch to my repo - works nicely.

@ceberlin If you were referring to my work above, please try out the v1.0.0rc2 branch as it pulls the files in from the npmcdn you referenced in your quote.

Nice one! Did you guys know that LibreOffice Online uses Leaflet to render the interface tiles?

[ceberlin]

@netcarver This fixed it!

[netcarver]

@ceberlin Great to hear that. I've switched my master branch over to Leaflet 0.7.7 from the npmcdn links you posted above. Could you try out the files from the master branch?

[Juergen]

Thanks for this awesome module!!!

Question: is it possible to remove loading the FontAwesome CSS from the LeafletMapHeaderLines (fe. at the options)? I use FontAwesome on a website and this will lead to that it will be loaded twice.

Best regards

[netcarver]

@Juergen If you pull the latest version of my master branch you'll be able to exclude the FontAwesome css file by doing the following:

<?php echo $map->getLeafletMapHeaderLines(false); ?>

Edited to add: Actually, you can just replace your copy of MarkupLeafletMap.module with the new one from the repository.

[Juergen]

Thanks! I will try this out.

@netcarver Now works well with the standard setup here. Does not work with the HERE map series (I think to remember the v100rc2 beta does).

[netcarver]

@ceberlin Thanks for checking that out. Regarding the HERE map series - I'm seeing the same here.

It would be great to add this to the module with the opportunity to select if you want to use it or not (in the field settings).

[Reid Bramblett]

This may seem simplistic, but how do I make a map where existing fields on the pages define the marker settings? In other words, rather than creating separate new fields on the page template for marker_icon and marker_color (and then laboriously having to fill them in each time), how I can use an existing field, and then merely provide some code denoting the corresponding changes I would like to the marker options. 

For example, for a travel site, each page has a "category" field (sleep, eat, see), and I would like that field to automatically determine the marker color and icon (anything with a category=sleep has marker_color = orange and marker_icon = bed, that sort of thing). 

I got this working on individual pages with "if" statements, but can't seem to get this working within the array needed to populate a map drawing from lots of pages.

Thanks!

Hi Reid,

Give this a shot. It's a template file that should do what you want if you are using my fork of the Leaflet module.

<!DOCTYPE html><?php

// Create our Leaflet map object. We do it here, before the header output, so we can use it to generate includes in the
// header itself.
$map = $modules->get('MarkupLeafletMap');

?>
<html lang="en">
    <head>
        <meta http-equiv="content-type" content="text/html; charset=utf-8" />
        <title><?php echo $page->title; ?></title>
        <link rel="stylesheet" type="text/css" href="<?php echo $config->urls->templates?>styles/main.css" />
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
        <?php echo $map->getLeafletMapHeaderLines(); ?>
    </head>
    <body>
        <h1><?php echo $page->title; ?></h1>
<?php

            // Extract the pages that will be turned into markers on the map
            $items = $pages->find("<YOUR SELECTOR HERE>"); // Update as needed


            // Setup the options for our map
            $map_options = array(
                // This routine formats the marker icon that gets used on the map.
                'markerFormatter' => function ($page, $marker_options) {
                    switch ($page->category) {   // Update with the fieldname you wish to check as needed
                        // For sleep category markers
                        case 'sleep' :
                            $marker_options['icon'] = 'bed';
                            $marker_options['markerColor'] = 'orange';
                            break;

                        // Add other cases as needed

                        // Here's the default marker setup
                        default :
                            $marker_options['icon'] = 'cutlery';
                            $marker_options['markerColor'] = 'blue';
                            break;
                    }

                    return $marker_options;
                }
            );

            // Generate the HTML and JS that will render the map with a marker for each page in the $items page array
            echo $map->render($items, '<YOUR MAP MARKER FIELDNAME HERE>', $map_options); // Update as needed
        ?>
    </body>
</html>

Please be aware that the icon colours you can choose from are pretty limited. Look at the 'markerColor' row in the table here for your options.

Hope that helps.

[Reid Bramblett]

Beauty, Netcarver. Just the ticket.

(And I had already resigned myself to working with leaflet's limited color palette to approximate the color scheme I'm using on the site.)

Thanks so much for this. Does in a few lines of code what used to take me ages to create by hand. Loving it.

[netcarver]

@Reid Bramblett

Glad that worked out for you.

@Mats

Thanks for pulling our changes back into your repository - great!  I made a few little tweaks to my repo since you did the merge; any chance of getting them pulled over to your repo as well?

>PS Nice change to your avatar! I like the look of those T-shirts 

[Mats]

@netcarver Repo is updated. 

Thats's my favourite shirt!  Thanks for setting up the store.

Hey guys!
I have a problem with this. When I put the  <?php echo $map->getLeafletMapHeaderLines(); ?> in the header of my template a get a

Error: Call to a member function getLeafletMapHeaderLines() on a non-object (line 34 of /www/htdocs/w00dd152/projekte/fabricius/site/templates/_header.php) 

I have checkt the permissons on the module files, everything is on 777. I also pressed the reload button (as suggested) on the module page in PW but still no luck. Iam running PW 3.0.30 devns

[flydev]

@jploch before calling the function, call the module : 

<?php
$map = $modules->get('MarkupLeafletMap');
echo $map->getLeafletMapHeaderLines();
?>

 

[jploch]

thx! I just figured this out, when reading the documentation, I must have missed it.

 

[jploch]

is there a trick, when using this with a repeater for multible markers in PW 3?
Here is my code, but thats not working:
 

<?php
$lage = wire('pages')->get("/lage/");
      $items = $lage->map_repeater; 
echo $map->render($items, 'map'); 
                 ?>

Also in the backend, the Address field is not clickable, when I use the Map Field in a Repeater 

Edit: It seems that the files for the module are not loading. I get an error in the console that the files are not loading.

[netcarver]

@jploch I've never used this in a repeater setup and I'm unsure of your field/template structure from that snippet. How have you actually structured things? What's the field called that holds the map markers?

Regarding the backend, the address is normally a read-only field that is set either by clicking on the magnifying glass in the top-right corner of the map and entering a description or by simply dragging the marker around. Have you tried moving the marker or using the search feature? If they don't work, it is possible there is a problem with some of the JS not loading properly. Please could you launch you browser dev tools and see if any of the JS assets are not loading.
