I have a page that is making a SOAP call to a webservice to get stock prices. I have a field where you can enter the company symbol, but when I submit the page, my variable for $symbol is blank. My input field is named symbol. Below is my code. This is on a Windows box with PHP 4.3.3.

<?
$symbol = "";
require_once('inc/nusoap.php');

$soapclient = new soapclient('http://services.xmethods.net/soap/urn:xmethods-delayed-quotes.wsdl',1);
echo "Symbol " . $symbol;

if (!$symbol) {
$rite_aid = $soapclient->call('getQuote',array('symbol'=>'rad'));
$ibm = $soapclient->call('getQuote',array('symbol'=>'ibm'));
$cvs = $soapclient->call('getQuote',array('symbol'=>'cvs'));
$wag = $soapclient->call('getQuote',array('symbol'=>'wag'));
$hershey = $soapclient->call('getQuote',array('symbol'=>'hsy'));
} else {
$results = $soapclient->call('getQuote',array('symbol'=>'$symbol'));
}
?>
<html>
<head>
<body>
<table width="100%" border="1" cellspacing="0" cellpadding="5">
<tr>
<td colspan="2" nowrap><strong>Stock Prices using PHP NUSoap Webservice </strong></td>
</tr>
<? if (!$symbol) {?>
<tr>
<td width="5%" nowrap>Rite Aid</td>
<td width="95%"><?=$rite_aid?></td>
</tr>
<tr>
<td nowrap>Walgreens</td>
<td><?=$wag?></td>
</tr>

<tr>
<td nowrap>CVS</td>
<td><?=$cvs?></td>
</tr>

<tr>
<td nowrap>IBM</td>
<td><?=$ibm?></td>
</tr>
<tr>
<td nowrap>Hershey Foods</td>
<td><?=$hershey?></td>
</tr>
<? } else {?>
<tr>
<td>
<?=$symbol?>
</td>
<td>
<?=$results?>
</td>
</tr>
<? } ?>
<tr valign="top">
<td nowrap>Enter symbol: </td>
<td>
<form name="stocks" method="get" action="webservice_stocks.php">
<input name="symbol" type="text" id="symbol">
<input type="submit" name="Submit" value="Get Stock Price">
</form> </td>
</tr>

</table>
</body>

Why is $symbol in quotes? That would cause PHP to treat it as a string, not a variable. Take those single-quotes out, and see what happens. ;)

nope, that didn't help. I have a print statement at the top of the page to print out $symbol and the values isn't even printing out there. You're change wouldn't have fixed that I don't believe.

You're setting $symbol to equal an emptry string...


$symbol = "";


...At the beginning of your code.

that's because I was trying to declare the variable. If I take that line out, I get

Undefined variable: symbol in D:\html\users\zluthorg\html\webservice_stocks.php on line 6


Even if i put global $symbol at the top, my $symbol variable is still blank.

Try setting $symbol to a default ticker symbol such as DIA...

If I set that at the top of the page, then it comes back with jsut the DIA results, which is what it should do. But, if I enter anything into my input box, nothing comes back. I even used form method "get" to make sure the symbol value was getting passed, and it is.

Try this...


<?
if(isset($_POST["symbol"])){
$symbol = $_POST["symbol"];
}
require_once('inc/nusoap.php');

$soapclient = new soapclient('http://services.xmethods.net/soap/urn:xmethods-delayed-quotes.wsdl',1);
echo "Symbol " . $symbol;

if (!isset($symbol)) {
$rite_aid = $soapclient->call('getQuote',array('symbol'=>'rad'));
$ibm = $soapclient->call('getQuote',array('symbol'=>'ibm'));
$cvs = $soapclient->call('getQuote',array('symbol'=>'cvs'));
$wag = $soapclient->call('getQuote',array('symbol'=>'wag'));
$hershey = $soapclient->call('getQuote',array('symbol'=>'hsy'));
} else {
$results = $soapclient->call('getQuote',array('symbol'=>'$symbol'));
}
?>

Nope, there is still nothing in $symbol when printing it out and I get all the results, not just the one I enter.

Did you change your form method to post?

I'll assume you meant that you got everything to work, not that you just changed the form's method and are excited about it. :p
