Module: Leaflet Map

[jploch]

I reinstalled the module, and now its working.
When I setup the repeater to allways open the items the map and magnifying glass icon seems to work.

Thanks for your help!

[jploch]

is it possible to use an image filed for the markers instead of the fontawesome option?
my code looks like this (it works with the FontIconPicker):
 

<?php
    $options = array(
    'height' => '100%',
    'markerIconColour' => 'black',
    'popupFormatter' => function($page) {
        $out[] = "<p>$page->headline</p>";
        return implode($out);
    },
    'markerFormatter' => function($page, $marker_options) {
        $marker_options['icon'] = $page->marker_icon; // Override the default icon for this marker.
        return $marker_options;
    }
);
      $items = $lage->map_repeater; 
echo $map->render($items, 'map', $options); 
                 ?>

Leaflet 1.0 final is out!

Hi!

I have problems displaying the map. It is not showing up.

I installed all the modules, setup the field and the template and put the following in my template file (home.php with delayed output):

echo $page->map->address;   // outputs the address you entered
echo $page->map->lat;       // outputs the latitude
echo $page->map->lng;       // outputs the longitude
echo $page->map->zoom;      // outputs the zoom level
$map = wire('modules')->get('MarkupLeafletMap');
echo $map->getLeafletMapHeaderLines();
echo $map->render($page, 'map');

Address, lat, lng and zoom are printed out, but there is no map. What am I doing wrong? I am not a coder.

Looks like sonething is messed up, the source code of the page looks like this

Is that the correct? It is the same problem as with the google map marker field

fliwatuet: Looking at the source, it seems you are echoing the map outside of your body and html elements.

[fliwatuet]

This is my home.php:
 

<?php namespace ProcessWire;

echo $page->map->address;   // outputs the address you entered
echo $page->map->lat;       // outputs the latitude
echo $page->map->lng;       // outputs the longitude
echo $page->map->zoom;      // outputs the zoom level
$map = wire('modules')->get('MarkupLeafletMap');
echo $map->getLeafletMapHeaderLines();
echo $map->render($page, 'map');

// home.php (homepage) template file.
// See README.txt for more information

// Primary content is the page body copy and navigation to children.
// See the _func.php file for the renderNav() function example
$content = $page->body . renderNav($page->children);

// if there are images, lets choose one to output in the sidebar
if(count($page->images)) {
    // if the page has images on it, grab one of them randomly...
    $image = $page->images->getRandom();
    // resize it to 400 pixels wide
    $image = $image->width(400);
    // output the image at the top of the sidebar...
    $sidebar = "<img src='$image->url' alt='$image->description' />";
    // ...and append sidebar text under the image
    $sidebar .= $page->sidebar;    
} else {
    // no images...
    // append sidebar text if the page has it
    $sidebar = $page->sidebar;
}

fliwatuet: please read the instructions for usage in https://github.com/madebymats/FieldtypeLeafletMapMarker

The parts:

"so simply add this somewhere before your closing </head> tag"

"In the location within the body of your HTML where you want your map to appear, place the following"

[fliwatuet]

I tried. But whenever I put

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

in the head section of _main.php I get this error message:
 

Error: Uncaught Error: Call to a member function render() on null in /home/html/portal.dev/site/templates/home.php:14

[fliwatuet]

Is it possible that php 7 causes this problem?

[netcarver]

@fliwatuet could you post the content of the head section of your _main.php please. It's fine to redact anything you feel is private if you need to.

Also, I use this module on a PHP7 installation and seem to have no problems with it.

[fliwatuet]

This is the original file (I took out the comments):
 

<?php namespace ProcessWire;

?><!DOCTYPE html>
<html lang="en">
<head>
    <meta http-equiv="content-type" content="text/html; charset=utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />
    <title><?php echo $title; ?></title>
    <meta name="description" content="<?php echo $page->summary; ?>" />
    <link href='//fonts.googleapis.com/css?family=Lusitana:400,700|Quattrocento:400,700' rel='stylesheet' type='text/css' />
    <link rel="stylesheet" type="text/css" href="<?php echo $config->urls->templates?>styles/main.css" />
</head>

When I add

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

right before </head> I still get the error message mentioned above when I use "echo $map->render($page, 'map');" in home.php!

BTW: the map in the backend is working.

[netcarver]

@fliwatuet

Sounds like $map is undefined in the home.php file. Please try this. In _main.php...

<!DOCTYPE html>
<html lang="en">
<head>
    <meta http-equiv="content-type" content="text/html; charset=utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />
    <title><?php echo $title; ?></title>
    <meta name="description" content="<?php echo $page->summary; ?>" />
    <link href='//fonts.googleapis.com/css?family=Lusitana:400,700|Quattrocento:400,700' rel='stylesheet' type='text/css' />
    <link rel="stylesheet" type="text/css" href="<?php echo $config->urls->templates?>styles/main.css" />
<?php
    $map = wire('modules')->get('MarkupLeafletMap');
    echo $map->getLeafletMapHeaderLines();
?>
</head>

in home.php...

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

Also, are you sure your field is actually called 'map'?

[fliwatuet]

Yes, the field is called map.

This is working fine:

$page->map->address
$page->map->lat
$page->map->lng
$page->map->zoom

 

I changed the code to your suggestion, now there is no error message anymore, but still no map...

[netcarver]

Does the page you are viewing using the home template actually have a value for the map field saved in it? Scrub that, it sounds like it does.

[netcarver]

Ok, if you inspect the page displaying the map with your browser tools, are there any JS errors or 404s showing up for the linked resources?

What do you mean? I added the map field to the home template and then edited the home page, put an address into the map field. I then edited the home.php template file and the _main.php.

No errors as far as i can see.

Hello @netcarver I'm having the same problem @fliwatuet reported above.

I supposed I've added everything correctly:

in my _init.php:

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

inside the <head></head> of my top_nav.php:

echo $map->getLeafletMapHeaderLines();

and then in my template file:

<?php echo $map->render($page, 'map'); ?> // yes, the field is called "map"

Inspecting the code I see all the css and js files in the <head> after this comment:

<!-- Styles supporting the use of Leaflet.js -->
.. css and js are here ..

And the correct <div> is generated by the module:

<div id="mleafletmap1" class="MarkupLeafletMap" style="width: 100%; height: 500px;"></div>

...but unfortunately the map is blank on the front-page of the site. 

I'm working on localhost on ProcessWire 2.8.35.

....got suggestions for me?

[Juergen]

I have also this problem sometimes (especially when I am not logged in). Could it be possible that there is a limit on the Leaflet service which supports only a specific amount of requests to a certain domain?

[netcarver]

If you open up the inspection tools in your browser and reload the page, are there any resources that fail to load or any js errors reported?

[3fingers]

Thanks for the reply @netcarver. I appreciate.

No errors anywhere in the console/inspector.

I've also tried to manually point the module to the 1.0.2 version of the leaflet JS and css (changhing both unpkg.com urls) but without luck, same blank div.

Have you got time to try to reproduce this strange behaviour?

 

 

[netcarver]

@3fingers So, all the resources are loading - and there are no errors - and there is no output? Ok - is this on a local development box or on a server I can take a look at?

Edited to add: I have seen a correctly set-up map fail to load if a browser is blocking scripts using an extension like noscript/umatrix/ublock-origin etc.

[3fingers]

...And there was the problem! I got an ad-blocker installed causing this issue on chrome. Unfortunately nowadays a lot of people have them turned on.

I'm going to investigate for a workaround, but It is kind of a remarkable issue for my project

In the meantime thanks for your support.

Hello, I have a question if this module can do the following.

I have a turtle that lives in one ore more states (US) or countries. I want to show this on a map on the page about that turtle. The input has to based on just the name of the state or country as I want to use the same also just for a text reference (like a tag).

Besides that I want a big map on a sperate page that combines all the turtles and shows which are located where with a hoover link to that turtle (page).

The final step is a page per state or country that show the map of that region on top and all related posts below...

It's a bit ambitious but I had to ask...

All possible.....for the maps you can select  what items you show on your map based on any field (for your specific turtle page):

$items = $pages->find("marker_colour=red");

My code here:

// LEAFLET MAP WITH BICYCLE ICONS
$items = $pages->find("marker_icon=bicycle");
$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->summary</strong>";
        $out[] = "<a href=\"$page->url\" ><img src=\"{$page->summary_image->url}\" class=\"image fit\"  /></a>";
        $out[] = "<img src=\"{$page->summary_image->url}\" width=\"200\" height=\"200\" />"; // ** NB: Use escaped double quotes if HTML attributes needed **
        return implode('<br/>', $out);
    }
);

 

and for items from different categories (species for your big map):

$items = $pages->find("marker_colour=red|green|blue");

 

Remember you can use:

'red', 'darkred', 'orange', 'green', 'darkgreen', 'blue', 'purple', 'darkpuple' & 'cadetblue'

and any icons from your version of Awesome icons: http://fontawesome.io/icons/

 

Beneath each map you can summarise revevant posts for each region or each species with the page find function based on an "options field type":

$features = $pages->find('species=loggerhead');

Does anyone know how you can populate the address field from another field on the template ? 

Eg; the title field is holding a country name, therefore would be nice if user does not need to type in country again, map just populates automagically.

Thx,
