I'm using the Zillow API in order to get some data from user inputs. So far I've been able to correctly use the API to get the desired data from a single input.
The issue I'm running into is when I try and convert my simple block of code into a function that I can reuse multiple times with multiple inputs.Eventually, I want the user to be able to uploaded a CSV file or something and run this function through multiple inputs.
Below is my code that is functioning properly:
HTML
<form action="logic.php" method="post">
<p>Address: <input type="text" name="address"></p>
<p>City/State: <input type="text" name="csz"></p>
<input type="submit">
</form>
PHP
//API Key
$api_key = 'XXXxxXXX';
//User Inputs
$search = $_POST['address'];
$citystate = $_POST['csz'];
//User Inputs Fromatted
$address = urlencode($search);
$citystatezip = urlencode($citystate);
//Get Address ID From API
$url = "http://www.zillow.com/webservice/GetSearchResults.htm?zws-id=".$api_key."&address=".$address."&citystatezip=".$citystatezip;
$result = file_get_contents($url);
$data = simplexml_load_string($result);
$addressID = $data->response->results->result[0]->zpid;
//Get Estimate from API (using adressID)
$estimate_url = "http://www.zillow.com/webservice/GetZestimate.htm?zws-id=".$api_key."&zpid=".$addressID;
$estimate_result = file_get_contents($zurl);
$estimate_data = simplexml_load_string($zresult);
$estimate = $zdata->response->zestimate->amount;
echo $estimate;
Now the issue is when I try and wrap both of these up into two separate functions in order to use them for multiple inputs.
$api_key = 'XXXxxXXX';
//User Inputs
$search = $_POST['address'];
$citystate = $_POST['csz'];
//User Inputs Fromatted
$address = urlencode($search);
$citystatezip = urlencode($citystate);
function getAddressID($ad,$cs){
//Get Address ID From API
$url = "http://www.zillow.com/webservice/GetSearchResults.htm?zws-id=".$api_key."&address=".$ad."&citystatezip=".$cs;
$result = file_get_contents($url);
$data = simplexml_load_string($result);
$addressID = $data->response->results->result[0]->zpid;
return $addressID;
}
$addressID = getAddressID($address, $citystatezip);
function getEstimate($aID){
//Get Estimate from API (using adressID)
$estimate_url = "http://www.zillow.com/webservice/GetZestimate.htm?zws-id=".$api_key."&zpid=".$aID;
$estimate_result = file_get_contents($estimate_url);
$estimate_data = simplexml_load_string($estimate_result);
$estimate = $estimate_data->response->zestimate->amount;
return $estimate;
}
echo getEstimate($addressID); //Calling function doesn't return anything
If essentially I'm doing this same thing as the first PHP example. Why isn't this working from within a function? Did I overlook something?
Ant help on this would be greatly appreciated.
