Embed Google Maps

[.for.ce.br]

Why not have a tag [googlemaps] [/googlemaps] to easily embed the interactive maps from Google Maps?

It should not be so difficult to create something like this...

[.for.ce.br]

Here is a simple PHP code that can do the job.

The user inserts the direct link from Google Maps (the direct link, not the link for embedding), between the tags [googlemaps] and [/googlemaps].

The code bellow takes the direct link inserted between the tags, and extract the coordinates and zoom level from it, to use them in the prefabricated code for iframe embedding.

PHP Code:

<?php

/*

Code by .for.ce.br (SkyscraperCity user)

Some code here to get the text between the tags [googlemaps] and [/googlemaps], the same way you can get the text between [youtube] and [/youtube]

Store the text you got in a variable called $intertags
*/


// Get the first 22 characters of the text stored in $intertags:
$check = substr($intertags,0,22);


// check if the text is a link from Google Maps:
if ($check == "http://maps.google.com") {


// Findind the coordinates and zoom level:
$position1 =  strpos($intertags, "ll=");
$position2 =  strpos($intertags, "&spn=");
$position3 =  strpos($intertags, "&z=");


$coordinates = substr($intertags,$position1+3, $position2-$position1-3);
$zoomlevel = substr($intertags,$position3+3, 2);

// The zoom level can have one or two characters, the code bellow handles with this issue:
$second = substr($zoomlevel,1,1);
$numbers = array("0", "1", "2", "3", "4", "5", "6", "7", "8", "9"); 
if (!in_array($second, $numbers)) { $zoomlevel = substr($zoomlevel,0,1); }


// Finally, this is the code of an iframe, pointing to Google Maps, with the coordinates and zoom level you got from the link inserted by the user:

$code = "<iframe width='650' height='400' frameborder='0' scrolling='no' marginheight='0' marginwidth='0' src='http://maps.google.com/maps?hl=en&amp;ie=UTF8&amp;ll=$coordinates&amp;z=$zoomlevel&amp;output=embed'></iframe><br />
<small><a href='http://maps.google.com/maps?hl=en&amp;ie=UTF8&amp;ll=$coordinates&amp;z=$zoomlevel&amp;source=embed' style='color:#0000FF;text-align:left'> Full view on Google Maps</a></small>" ;

echo $code;

}


?>

The code is free, you can use it if you want.

iframes would be a security risk and the correct way to embed maps is to register for the Google Maps API and use that, but the work required to do something like that would be more complex.

(note: this is my personal opinion and does not represent the viewpoint of site admins)

[.for.ce.br]

I think iframes would not be a security risk if the "src" property is rigidly controlled. The PHP script gets the direct link, extracts the coordinates and zoom level from it, and insert them in the "src" property of the iframe. The user will not be allowed to determine what the src will be.

Using the Google Maps API would require in first place register to get an ID with Google. It also can be done, but is a little bit more complicated. In return, the API uses a DIV, not an IFRAME...

[.for.ce.br]

Anyway, if the Google Maps API is used, the code I posted above can be used to obtain the $coordinates and $zoomlevel from the direct link between the tags, and then the variables are inserted into the API's function "map.setCenter".

PHP Code:


<?php

$setcenter = "map.setCenter(new GLatLng($coordinates), $zoomlevel, G_NORMAL_MAP);" ;

?>

I'm here just to clarify that, since I was unfairly banned from Skyscrapercity, I no longer will be offering this PHP code for free to this website. I withdraw the offer of the above PHP code. Skyscrapercity can not use the code created by me any time in the future.

I no longer have any interest about this website packed with arrogant, autoritarian and foolish moderators.

Goodbye.

I'm still gonna use your code though
