[RESOLVED] passing php vars to javascript

[dcjones]

Hi All,

before you ask I have read all the post regarding "passing php vars to javascript" and I cannot find the solution to my problem.

PROBLEM

I have the following code:

<a href="http://www.mydomain/location_map.php?lat=<?php echo $row_accomm_counties['lat']; ?>&lon=<?php echo $row_accomm_counties['lon']; ?>

As you ca see the url apends the content of the 2 vars:
$row_accomm_counties['lat'];
$row_accomm_counties['lon'];

CALLED PAGE (location_map.php)

This page just has javascript in it:

<script type="text/javascript">
//<![CDATA[

var map = new GMap(document.getElementById("map"));
map.addControl(new GSmallMapControl());
map.centerAndZoom(new GPoint([COLOR=Red]-4.437103271484375[/COLOR], [COLOR=Red]55.86250064959305[/COLOR]), 4);

//]]>
</script>

WHATS REQUIRED

As you can see the javascript has 2 set of map references:

-4.437103271484375 ( lon )
55.86250064959305 (lat )

Is there a way I can use the 2 PHP vars
$row_accomm_counties['lat']
$row_accomm_counties['lon']
and sub them for the 2 map references.

I'm ok'ish at PHP but not so good with javascript.

I have not place the PHP holders because in this case it makes the code not so readable.

Can anyone help please.

instead of:

map.centerAndZoom(new GPoint([-4.437103271484375, 55.86250064959305), 4);

try:

map.centerAndZoom(new GPoint(<?php echo $_GET['lat']?>, <?php echo $_GET['lon']?>), 4);

of course you really should do some input valiadation at the start to makesure that lat and lon are the kind of values that you expect 🙂
