I am trying to get the distance and duration into a php variable so I can call it and display it later.

its currently in a javascript.

code:


function onGDirectionsLoad(){ 

distance = gdir.getDistance();

document.getElementById("distance").innerHTML = distance.html;

duration = gdir.getDuration();

document.getElementById("duration").innerHTML = duration.html;

Any ideas.

i want like $distance = the output that is produced about

I am using the google maps API and that statement produces the required output I need.

But I need to be able to call the function in php afterwards.

so i can carry the following for example.

$time = (whatever you do);
$distance = (whatever you do);

$time+$distance*100 = $price

echo $price;

So need to get the distance from the script after it is run into php.

firstly you will need the form to action a php page, then the php page to get the variables from the form

something like

$distance = htmlentities($_REQUEST['distance']);
$duration = htmlentities($_REQUEST['duration']);

heres a forumla i use on vagweb

code:
$distance=sqrt(pow(($userx-$homex),2)+pow(($usery-$homey),2))/1000;

	$distanceadjust = $distance * 0.19;

	$distance= $distance + $distanceadjust;

	$distancekm=round($distance, 0);

yeah when you submit that form it calls the javascript function, if you want to send the variables to php the action="#" will need to be action="somepage.php"

you might be better off putting the javascript in a php page and echo'ing it out when when you call the php page, without testing it though i dont know if that will work properly

if you put the html form elements in the php page and echo them out at the same time it should work.

Php has to be actioned, you cant run it inline like that, the page has to be refreshed, or the information sent to the script,

Steve already showed you this, you said you have a form, which is great but this has to send information to a php page which can take the information and send it back for the javascript to process (if you're still going to us the JS)

I speratored the form from the script.

then added the following as steve suggested

code:


function onGDirectionsLoad(){ 

distance = gdir.getDistance();

document.getElementById("distance").innerHTML = distance.html;

duration = gdir.getDuration();

document.getElementById("duration").innerHTML = duration.html;

 } 



</script> 



<?php

$distance = htmlentities($_REQUEST['distance']);

$duration = htmlentities($_REQUEST['duration']);

?>

but it errors in the php bit with Notice: Undefined index: duration
