Hi,

I am trying to alter the events module so that you can give the event a location which will be displayed on a google map on the website.

At the moment I have added fields so you can enter longitude and latitude but what I would really like to do is add in a google map so people can drag the marker to the location they want and that will generate the longitude and latitude.

I have the googlemap code working on a test file http://bible.bpweb.net/googlemaptest.html but I cant figure out how to add it to the admin page. I am not getting any error messages just an empty space where the map should appear. At the moment I am not concerned about linking it to any of the form fields, I am just trying to get the map to appear!

I have changed the template to

Code: Select all

{$startform}
<div class="pageoverflow">
	<p class="pagetext">*{$prompt_short}:</p>
	<p class="pageinput">{$input_short}</p>
</div>

	<p class="pagetext">Summary:</p>
	<p class="pageinput">{$input_summary}</p>

Check input text (lon and lat)?

sorry, i'm not sure what you mean?

at the moment I am not trying to output the long and lat, I am just trying to get teh map to appear and a search field so you can type in a location and have it displayed on the map

That input are not lon and lat but about m1_lon and m1_lat

I have not tested but I think that should work (attention to map key)

Ok I have got it working with a few tweaks to the javascript.

This is the finished template file if anyone would like to do something similar

Code: Select all
