[Google Maps API v3] Re: Geocoder fail
Thanks, just tried it again with your advice. I zoomed out to show entire UK and then did the search and it worked, I think I was zoomed in too much and it was just missing showing manchester at the time so it wasn't in the "viewport". A little annoying but I suppose its something to bear in mind.

[Google Maps API v3] Merge my db with establishment types request
I want to search my db for some locations and display them on a google map. I'll probably only be bringing back about 20 but they may be a mix of establishment types. I'd then like to allow the user to filter the results so it only shows particular establishment types. Let's say it brings back "bar"s and "night_club"s but when the user de- selects bars (by unchecking a checkbox for "bar" establishments) there's only 1 night_club left out of the 20 results but if the user had just been able to search my db for locations that I have that google says are night_clubs then there could have been 3 displayed but they were outweighed by all the bars that were returned closer to a particular position. Would I need to store the establishment type when I save the location info to my database so that a user could filter particular establishment types or is there a better way of doing this that I've not thought of?

Yup you are correct, it should be "?z=""&x=" "&y="
Hmmm, my guess is it's probably because you have cached some of the
images in chrome while tweaking it. Try dumping your temp. internet
files, then when you revist the page click Ctrl-F5 to do a force

[Google Maps API v3] Re: Bad requests on custom tile overlays
Your welcome, i'm also very pleased to have this sorted. On a side note, you don't need the forward slashes in your javascript, only your PHP. Even though it works it is probably best to remove them as it might throw up an error in some browsers. With $_GET, you stick a ? on the end of the URL. Then the variable name, followed by the equals sign and the value (number/letters etc.). If you want to add more than one set of values and variables, seperate them with the ampersand (&) symbol. You need the slashes in the PHP obviously because you are telling it to look for the next folder. On Jul 30, 10:27 pm, Jason wrote: > Got it.. Thanks John..

My tms is a bit different, zoom and x are folders and y is the tile png. Changing the php $filename to: $filename = "/var/www/merge/tiles/" . intval($_GET['z']) . "/" .intval($_GET['x']) .

".png"; and then in the map code changing the return statement to: return "/merge/tiles.php?z=" + zoom + "/&x=" + coord.x + "/&y=" + (Math.pow(2,zoom)-coord.y-1) + ".png"; seems to work for me.

At a quick glance, have you noticed the $filename is expecting to
output a link in the following format:
$filename = /var/www/merge/tiles/zoom_x_y.png
But your files appear to me to be organised into something like /var/

Take a closer look at the $filename, I suspect you need to change it a
bit (look at the . "_" . parts especially). Let me know how it goes.

[Google Maps API v3] Re: Bad requests on custom tile overlays
Thanks for posting that Kesuke! It would be great to get this working.
Those 404s have been a headache for quite a while.
I've implemented your example on a small test page and I'm not seeing
any tiles. I'm not too familiar with PHP but I did check that safe
mode is "off" with phpinfo.
My php looks like this:
the tiles are at:
http://69.164.209.124/merge/tiles/
and the page is here:
http://69.164.209.124/merge/mimagery.html
Any idea what I'm missing here?
Thanks in advance for a steer in the right direction.

[Google Maps API v3] Re: conversion to V3 questions
1.) This guide should help explain how to call the map in V3: http://code.google.com/apis/maps/documentation/javascript/tutorial.html Essentially your map code will go in a javascript function, and in the body tag you will call that function. In the 'hello world' example over at that link you will see we usually call it initialize(); but you could rename it to whatever you want obviously provided both the function and the call have the same name. You don't need to call GUnload anymore, because map assets are (in theory at least) dynamically cleared by the browser and the API as it goes. Its a little bit contentious, you can read more about it at this link if you really want, or just take my word for it: http://code.google.com/p/gmaps-api-issues/issues/detail?id=772 2.) Per the 'hello world' example at the first link, you don't need to include an IE7 standards mode meta-tag in V3 as far as I am aware.

[Google Maps API v3] Re: Bad requests on custom tile overlays
Correction, after deleting my firefox cache to see the full benefits
Google PageSpeed has gone from ~45/100 before these changes to
~90/100! Thats pretty solid stuff for a map with 1.5mb of data to load
just on initialize. It has also cut the number of 404s from ~100 on
load down to 0.
Furthermore, the benefits of setting longer max-ages on the files
reduces the actual transfer size for a second-visit down by over 50%
to 650kb. Obviously if you view a new area of the map you have to
download fresh tiles, but on startup it makes a big difference.
The PageSpeed addon did have a slight gripe with me feeding it the
same 1px clear.png image from different URLs but it doesn't seem to
appreciate that is the lesser of two evils. So I set a very long
expiry on the clear.png and PNGcrushed it down to a massive 69 bytes
and PageSpeed seems to be ignoring it now.

[Google Maps API v3] Re: Bad requests on custom tile overlays
Okay, thanks everyone – the PHP solution works great!
So here is a guide for Jason or anyone else who stumbles across this;
1.) Make a new PHP file with the following code:
Basically this PHP script will check to see if the file exists. If it
does it will return the file. If it doesn't, it will return a 1px
empty image, in this case called 'clear.png'. The only stuff you
should need to change are the paths to clear.png and $filename. Be
aware that PHP safe mode can probably screw this up.
NOTE: counter-intuitively, PHP looks for the true file destination NOT
the URL. So you need to know your servers C:// style path to the file.
There are ways around it using fopen() but you would need to look
those up - not realising this gave me headaches.
2.) Now, go into your map javascript and point to the PHP file instead
of the image URL. Specify the zoom/x/y co-ords which we will detect
using $_GET in our PHP script. If you don’t know what $_GET is have a
look on google as its quite fundamental – but in basic terms you send
variables and their values to a PHP document by appending the URL with
the format “map.html/?var=value&othervar=value”. PHP then plucks those
values and variables out for you to use.
So, using the above example:
function createImageMapType(id) {
return new google.maps.ImageMapType({
getTileUrl: function(coord, zoom) {
return "/tilefinder.php?z=" + zoom + "&x=" + coord.x + "&y=" +
coord.y;
},
tileSize: new google.maps.Size(256, 256),
isPng: true,
opacity: true
});
}
I hope this helps. So far it seems to be working well on my site,
there is a noticable improvement in load times and my Google PageSpeed
score got pushed up by about 20-30 points. If you want to improve
things further, I suggest setting a higher max-age (probably of 28
days/2419200) and also adding a last modified content-type header.

[Google Maps API v3] Re: Reverse Geocoding does not works if I return the result in a function
> It seems this function was called after the rest of all the code.
> Why?
Because it is asynchronous.
geocoder.geocode( {'address': address}, function( ... ) { ... }
only sends a request to Google. The callback function is NOT run at
this time.
The browser then carries on and executes the code that follows.
For example
geocoder.geocode( {'address': address}, function( ... ) { ... }
alert ('banana');
the alert will display BEFORE the results get back from Google.
Sometime later, the results come back and the callback function will
be run.
In the case of your code snippet, your callback refers to variables
'map' and 'addr' and 'userPosition' that may or may not be within the
scope of the callback function when it runs, you need to be careful
about that.

[Google Maps API v3] Re: Reverse Geocoding does not works if I return the result in a function
It's a strange event!
For example, I have the same problem in another function which
converts address -> coordinates
*
// creo la mappa a partire da un indirizzo passato come parametro o
quello di default
function searchAddress(addr)
{
var address;
if(addr == null)
address =
document.getElementById("address").value;
else
address = addr;
var geocoder = new google.maps.Geocoder();
geocoder.geocode( {'address': address},
function(results,status)
{
if(status ==
google.maps.GeocoderStatus.OK)
{
if(addr == null)
map.setCenter(results[0].geometry.location);
else
{
userPosition =
results[0].geometry.location;
alert("userPosition = "
+userPosition);
}
}
else
{
alert("Error: " +status);
}
});
}
***
In this case I put the code (to store value in a variable) in "(status
== google.maps.GeocoderStatus.OK)" but it does not works!
It seems this function was called after the rest of all the code.
Why?
