return one value in an array from a function

[jrough]

I tried to return the value $pointer from the addAddress function(see***) but I only got latitude and longitude numbers. Then I tried returning it as $pointer[$htmlMessage']= $map->addAddress($value); and that gave me this[ Array (

 => )]

can you tell me how to get the $htmlMessage from the function into this code?
many thanks,

foreach($addrUnique as $key => $value){
try{
$map->addAddress($value);
$pointer = $map->addAddress($value); *****
print_r($pointer);
}
$map->printGoogleJS();
[/code]

---------function---------------
function addAddress($address,$htmlMessage=null){
if (!is_string($address)){
die("All Addresses must be passed as a string");
}

/
$apiURL = "http://local.yahooapis.com/MapsService/V1/geocode?appid=JezVqMLV34G_VJeKk_o8kM12GbWa1PiTotJPt6OxwowFgMb73vEJ.VUdXXp92w--&location=";

$addressData = @file_get_contents($apiURL.urlencode($address));

    $results = $this->xml2array($addressData);

    if (empty($results['ResultSet']['Result']['Address'])){
        $pointer = count($this->invalidPoints);
        $this->invalidPoints[$pointer]['lat']= $results['ResultSet']['Result']['Latitude'];
        $this->invalidPoints[$pointer]['long']= $results['ResultSet']['Result']['Longitude'];
        $this->invalidPoints[$pointer]['passedAddress'] = $address;
        $this->invalidPoints[$pointer]['htmlMessage'] = $htmlMessage;
      }else{
        $pointer = count($this->validPoints);
        $this->validPoints[$pointer]['lat']= $results['ResultSet']['Result']['Latitude'];
        $this->validPoints[$pointer]['long']= $results['ResultSet']['Result']['Longitude'];
        $this->validPoints[$pointer]['passedAddress'] = $address;
        $this->validPoints[$pointer]['htmlMessage'] = $htmlMessage;
    }
return $pointer['htmlMessage'];

}

How about:

   return $htmlMessage;
}

[jrough]

the return $htmlMessage doesn't work. I think the reason is I need to put the value
in
$map->addAddress($value); so if I try to return a value from the function in the next line in the for each looping through the list it doesn't seem to store any value, either $pointer returned or $html returned.

$html = map->addAddress($value); You cannot do both of these lines together can you?

I am going back to using public $invalidPoints and $validPoints
Is this right? To capture the value depending on whether it was valid or invalid?

foreach($addrUnique as $key => $value){
$map->addAddress($value); 
if ($map->validPoints['htmlMessage']!= null){
   $html = $map->validPoints['htmlMessage'];
}else{
if ($map->invalidPoints['htmlMessage']!=null){
    $html = $map->invalidPoints['htmlMessage'];
}

thanks,

According to the code you posted, $map->validPoints and $map->invalidPoints are arrays containing (as their name suggests) multiple points. Each with their own lat, long etc.

Since all the information is being stored in $map->validPoints and $map->invalidPoints, have you tried print_r($map->validPoints) to see just what it contains? It will be an array of entries, each one with its own lat, long, htmlMessage etc. elements. Which of those entries (and hence which htmlMessage) you actually want is something I can't answer for you.

I printed out $map->invalidPoints; and $map->validPOints;
I got empty values for [htmlMessage]=> )
I did get all the addresses and long and latitudes in the $map object
but the $htmlMessage is not being passed into the function therefore that value is blank.
Can I do a Javascript to get the HTTP response from yahoo? I have to pass $htmlMessage to the addAddress() function. I really don't know how to get the status code from Yahoo. I think it comes in XML.

I think it is because the input to the function $htmlMessage=null
but I don't know how to pass the value of $htmlMessage to the function?

It come like this:
<Error xmlns="urn:yahoo:api">
The following errors were detected:
<Message>error message</Message>
</Error>

It comes from Yahoo in XML then the XML2array() function parses it

function addAddress($address,$htmlMessage=null){
 if (!is_string($address)){
    die("All Addresses must be passed as a string");
  }

$apiURL = "http://local.yahooapis.com/MapsService/V1/geocode?appid=JezVqMLV34G_VJeKk_o8kM12GbWa1PiTotJPt6OxwowFgMb73vEJ.VUdXXp92w--&location=";

$addressData = file_get_contents($apiURL.urlencode($address));

    $results = $this->xml2array($addressData,$htmlMessage=null);

    if (empty($results['ResultSet']['Result']['Address'])){

        $pointer = count($this->invalidPoints);
        $this->invalidPoints[$pointer]['lat']= $results['ResultSet']['Result']['Latitude'];
        $this->invalidPoints[$pointer]['long']= $results['ResultSet']['Result']['Longitude'];
        $this->invalidPoints[$pointer]['passedAddress'] = $address;
        $this->invalidPoints[$pointer]['htmlMessage'] = $htmlMessage;

      }else{
        $pointer = count($this->validPoints);
        $this->validPoints[$pointer]['lat']= $results['ResultSet']['Result']['Latitude'];
        $this->validPoints[$pointer]['long']= $results['ResultSet']['Result']['Longitude'];
        $this->validPoints[$pointer]['passedAddress'] = $address;
        $this->validPoints[$pointer]['htmlMessage'] = $htmlMessage;

    }


}

As far as I can see in your code for that function, the only way $htmlMessage gets set is if the calling code supplies it as the optional 2nd parameter to the function call.

the function that sends a rest request to yahoo to get the lat & longitude of the address in XML. Then it parses the address data XML into an array. It all works and I get a yahoo map. The problem is I have to trap for errors like 503 service unavailable. I get the XML address data results from this XML.

Here is and example of the XML geocode results:
1. <?xml version="1.0" encoding="UTF-8"?>
2.

3. <ResultSet xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4. xmlns="urn:yahoo:maps"
5. xsi:schemaLocation="urn:yahoo:maps http://local.yahooapis.com/MapsService/V1/GeocodeResponse.xsd">
6. <Result precision="address">
7. <Latitude>37.416384</Latitude>
8.

9. <Longitude>-122.024853</Longitude>
10. <Address>701 FIRST AVE</Address>
11. <City>SUNNYVALE</City>
12. <State>CA</State>
13.

14. <Zip>94089-1019</Zip>
15. <Country>US</Country>
16. </Result>
17. </ResultSet>

however this is the error results if the address is wrong
<Error xmlns="urn:yahoo:api">
The following errors were detected:
<Message>error message</Message>
</Error>

I don't know how to get this error message then I have to parse it?This error message should go into $htmlMessage. BUt how?
This is the function:

If you notice the $htmlMessage is null. I need to pass the $htmlMessage into the function. I don't know how to get it from Yahoo. It seems like the $apiURL should have a callback function of some kind.

    function addAddress($address,$htmlMessage=null){
     if (!is_string($address)){
        die("All Addresses must be passed as a string");
      }

$apiURL = "http://local.yahooapis.com/MapsService/V1/geocode?appid=JezVqMLV34G_VJeKk_o8kM12GbWa1PiTotJPt6OxwowFgMb73vEJ.VUdXXp92w--&location=";

 $addressData = file_get_contents($apiURL.urlencode($address));



        $results = $this->xml2array($addressData);

        if (empty($results['ResultSet']['Result']['Address'])){

            $pointer = count($this->invalidPoints);
            $this->invalidPoints[$pointer]['lat']= $results['ResultSet']['Result']['Latitude'];
            $this->invalidPoints[$pointer]['long']= $results['ResultSet']['Result']['Longitude'];
            $this->invalidPoints[$pointer]['passedAddress'] = $address;
            $this->invalidPoints[$pointer]['htmlMessage'] = $htmlMessage;

          }else{
            $pointer = count($this->validPoints);
            $this->validPoints[$pointer]['lat']= $results['ResultSet']['Result']['Latitude'];
            $this->validPoints[$pointer]['long']= $results['ResultSet']['Result']['Longitude'];
            $this->validPoints[$pointer]['passedAddress'] = $address;
            $this->validPoints[$pointer]['htmlMessage'] = $htmlMessage;

        }


    }
