Module: Leaflet Map

uliverse · October 14, 2019

I have encountered a bug: as soon as I turn on the cache function (Processwire built-in) the maps don't load any more on Chrome. Firefox works, though. Any idea what causes this?

I'm trying to automatically add pages containing a field with this fieldtype. while all other fields are populated as expected the lat/lng part of my geolocation field keeps its default values. Is there a special syntax to address these

I don't really understand why, but it works, if I change lat lng values in a second step.

$newPoi = $pages->add("tmbPoi", "$parentPage->url", [
                    'name' => $thisPoiId,
                    'title' => $poi['name'],
					...
					]

$newPoi->geolocation->lat = $lat;
$newPoi->geolocation->lng = $lng;
$newPoi->of(false);
$newPoi->save('geolocation');

Hi @All,

When I turn on cache, the map is blank. What variable should I exclude or...!?

MarkE · November 18, 2019

This is a really nice module, but why is the fully working version only in the 'dev' release?

EDIT: Having said that, I now find I have the same problem as the previous poster. It all works fine on my Dev machine. But in the live environment it is blank.

EDIT 2: In my case, the problem was simple - just forgot to upload the additional lines in the <head> - i.e.

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

Is that your problem @Leftfield?

Leftfield · November 23, 2019

@MarkE thank you for your answer but it doesn't help since I load files manually (except main js). Anyway, I will remove module for two reasons (both not fault of the module):
First: Lon and Lat are not compatible with Google Maps for my country. There is some wild offset.
Second: Will test for SEO, doubt is that Google doesn't rank website with Open street map.

So using the dev version, the geo coding is working. (also when you add a key to the google geo call). But I now run into an issue where the map is grey out in the "edit page" set-up. I cant fill in an address either as the input field is disabled. @hellomoto mentioned this issue before. Did you got a chance to fix it? @Mats ay pointers?

DL7 · November 29, 2019

So, somehow I got it fixed, by changing the Default Map Tile Provider in the field setting. Somehow the default OpenStreetMap.Mapnik doesnt work for me.

Hello,

After spending hours trying to find a solution, I ask the community for help... I have a map showing up on page load. It works fine but it takes quite a while. You can see it in action there : https://planetalert.tuxfamily.org/world/6ef (be patient, loading is terrible)

I have already tried caching parts of my page (the different lists) and it's ok, but I can't manage to cache the map. So I would like to load the 2nd tab (when clicking on the faces icon at the top-left corner) by default to get a fast loading page and have my map loading on an ajax call. But all my tests are complete failures ?

Here's my ajax part of code :

	[...] // Setting $allElements (for markers) and $options there
	$map = $modules->get('MarkupLeafletMap');
$out .= $map->getLeafletMapHeaderLines();
$out .= $map->render($allElements, 'map', $options);

Eventually, I get my map box, but it stays empty ?

Any advice, please ?

@celfred: This has nothing to do with the map itself. It takes 15 seconds four your server to generate a response, after that the map and all of its content loads fast. So I assume your process of building the list of markers is somewhat ineffective. Can you show the code with which you generate the $allElements Array?

@MadeMyDay Thanks for your reply. From your comment, I have tried testing my $allEments function (it takes 0.415s on localhost). You can see the code there : https://framagit.org/celfred/planetAlert/blob/master/site/templates/my-functions.inc (function teamFreeWorld() line 1468) BUT I have also tried this :

	$out .= $map->render($allElements->eq(0), 'map', $options);

And the page now loads a lot faster (I can tell the difference even on localhost) ! So maybe it's because I have 56 (or even 96) markers, with a photo... ? What could I do, then ?

I hope you (or anybody else) will have other pieces of advice for me ? My site has improved so much over the years thansk to the help of this community (and I have learned so much - you can tell I'm not a pro dev ? - I'm a teacher and the website is for motivating my middle-school pupils)

EDIT : Well, for the moment, I've just removed the images in my map markers tooltips and it loads faster...

SiWhitt · August 3, 2020

I have this module implemented on a website and all works well. It currently outputs popups as per the attached image – the first line is generated by the module/options but I can't seem to override it in any way. The map pull sin information from it's child pages, and the title in the pop up links to the child page, but I want to change this so it links to the company's website instead (as per the url further down the pop-up). I've tried changing the 'markerLinkField' / 'markerTitleField' options, leaving them blank, etc but that either displays as per the attached or stops the pop up working.

Any thoughts much appreciated.

Issue 1:

Why do I get lots of random Russian (?) text when I try to look up addresses? And the location search results are awful; the system suggests random street addresses (with lots of Russian) when you type in something basic like 'London, England'. Full addresses seem to work better, but only without postal codes - 'nothing found' when you try to search with postal codes included.

Issue 2:

Maps show up in the admin area, but not on the front-end. I have another version of the same site where they do show up on the front-end without problems, so am a bit puzzled where the problem could be. What are typical causes I could check?

Edit:

The problem with the map not showing up on the front end (Issue 2) had something to do with this error showing up in Chrome Inspect/DevTools:

Uncaught TypeError: $ is not a function at (index):529

Something with jQuery. The error disappeared when I copied module files from another site where Leaflet Map did work. Not sure where the cause of the error is exactly.

Uncaught TypeError: $ is not a function at (index):529

I have the same issue with a new install.

In dev tools everything is rendered, just no map at all.

Check that you are loading jQuery in the frontend.

Your right. I did not notice it was not loaded. Thanks @Beluga

webhoes · September 18, 2020

Hello,

is it possible to render the input field on a frontend template (for loggedin users only).

I tried this:

<?php 
$m = $modules->get('InputfieldLeafletMapMarker');
$m->render();
?>

This generates errors for empty variables.

1×	PHP Notice: Trying to get property 'lat' of non-object in ...\InputfieldLeafletMapMarker.module:102
1×	PHP Warning: Creating default object from empty value in ...\InputfieldLeafletMapMarker.module:102

Hi there,

thanks for providing the Leaflet Map Marker module - very useful!

One thing I couldn't figure though is: how can I set NO default address to a field? I need to have the map as an optional field for a given template.

Thanks for any advice.

@jor

Not sure if this is the correct way, but on my map template I wrap my code with:

if($page->marker->address) {

}

e.g.

if($page->marker->address) {

	$map = wire('modules')->get('MarkupLeafletMap'); 
	$options = array(

    'markerFormatter' => function($page, $marker_options) {
        			if ($page->marker_icon->title) {
                        $marker_options['icon'] = $page->marker_icon->title;
                    }

                    if ($page->marker_colour->title) {
                        $marker_options['markerColor'] = $page->marker_colour->title;
                    }

                    // And the icon colour. This is another text field. Colour values like White, Black or an RGB value are ok here.
                    if ($page->marker_icon_colour->title) {
                        $marker_options['iconColor'] = $page->marker_icon_colour->title;
                    }    
        return $marker_options;
    },

    'popupFormatter' => function($page) {
        $out[] = "<strong>$page->headline</strong>";
        return implode('<br/>', $out);
    }

);
       

$content.= $map->render($page, 'marker', $options);

}

If no address is entered, no map is shown.

Hey there,

I don't know if this might help smeone (and if I did it the right way), but I had an issue as follow : all maps worked on my site except 2 monuments which didn't show any map. I noticed they had a single quote in their name and if I got rid of it the map appeared.

I then ended up doing this (in my '$opitions' array) and it worked :

	'popupFormatter' => function($page) {
 $page->title = str_replace('\'', '\\\'', $page->title); // Dirty hack (no map if single quote in title)
 $out[] = '<strong>'.sprintf(__('In %1$s, in %2$s'), $page->city->title, $page->country->title).'</strong>';
 $out[] = "<p class=\"text-center\"><img src=\"{$page->photo->eq(0)->getCrop('thumbnail')->url}\" /></p>"; // ** NB: Use escaped double quotes if HTML attributes needed **
 return implode('<br/>', $out);
},

Again, it might sound a bit hacky, but it works for me and maybe it can be useful to someone...
