PHP SOAP XML Post

Hi,

I am new to PHP and SOAP requests so please forgive the question...

I have an XML script (attached) that I want to be able to use a basic web form to change 2 variables. I want to create a PHP script that allows me to type in the Pattern and the Description and then submit it to my SOAP Request server. I know how to submit via CURL.

Just wondering if someone could help me write something in PHP that would accomplish this, nothing fancy, just a basic input asking for the Pattern and Description then Submit.


<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://www.cisco.com/AXL/API/8.5">
   <soapenv:Header/>
   <soapenv:Body>
      <ns:addLine sequence="?">
         <line>
            <pattern>?</pattern>
            <description>?</description>
               </line>
      </ns:addLine>
   </soapenv:Body>
</soapenv:Envelope>

Any response back from the server would be good also if it can print on screen.

PHP forms are described in the introductory tutorial here:
http://php.net/manual/en/tutorial.forms.php

Heredoc notation might be helpful here.  I'll try to give you an example in a moment.  If you're new to PHP, this article can help you find dependable learning resources.

Please see http://www.iconoun.com/demo/mark_06.php

You would make the cURL call to the web service near lines 28-30.  The existing code there is just for my proof of concept to see that the string variable substitution worked.

<?php // demo/mark_06.php
error_reporting(E_ALL);

// http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/PHP/Q_28395751.html

// IF THERE IS A POST-METHOD REQUEST
if (!empty($_POST))
{
    // RETRIEVE VALUES OR ACCEPTABLE DEFAULTS
    $p = !empty($_POST['p']) ? $_POST['p'] : NULL;
    $d = !empty($_POST['d']) ? $_POST['d'] : NULL;

   // CONSTRUCT THE XML DOCUMENT USING HEREDOC SYNTAX
	$xml = <<<ENDXML
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://www.cisco.com/AXL/API/8.5">
   <soapenv:Header/>
   <soapenv:Body>
      <ns:addLine sequence="?">
         <line>
            <pattern>$p</pattern>
            <description>$d</description>
         </line>
      </ns:addLine>
   </soapenv:Body>
</soapenv:Envelope>
ENDXML;

    // MAKE THE cURL CALL HERE
    echo '<pre>';
    echo htmlentities($xml);
}

// IF THERE IS NO POST METHOD REQUEST, CREATE THE FORM
else
{
    $form = <<<ENDFORM
<form method="post">
Pattern: <input name="p" />
Description: <input name="d" />
<input type="submit" value="Go!" />
</form>
ENDFORM;

    echo $form;
}

Line 28, where it says "MAKE THE cURL CALL HERE"
i phave it primt out "completed request"
Yes. remove lines 29 and 30, and instead insert this line.

echo 'completed request';

Thanks for that, you have been very helpful however I am having trouble getting the CURL commands correct.

In CLI this is the CURL commands I use....

curl -k -u cups:password1! -H "Content-type: text/xml;" -H "SOAPAction: CUCM:DB ver=8.5"  -d  https://192.168.16.245:8443/axl/

im having trouble conversting that into the CURL for PHP

This is the code I am currently trying

<?php // demo/mark_06.php

    // RETRIEVE VALUES OR ACCEPTABLE DEFAULTS
    $p = !empty($_POST['p']) ? $_POST['p'] : NULL;
    $d = !empty($_POST['d']) ? $_POST['d'] : NULL;

   // CONSTRUCT THE XML DOCUMENT USING HEREDOC SYNTAX
	$xml = <<<ENDXML

         </line>
      </ns:addLine>
   </soapenv:Body>
</soapenv:Envelope>
ENDXML;

$username = 'cups';
$password = 'Password1!';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://192.168.16.245:8443/axl');
curl_setopt($ch, CURLOPT_USERPWD, $username.':'.$password);

curl_close ($ch);



	echo '<pre>';

For some reason, PHP programmers seem unique among software developers in the matter of ignoring return values from functions and error conditions.  There's often a reason for a problem that is obvious if only the PHP script tests for it.  Of course, with SOAP, everything is obscure.  If you can find a RESTful API instead of SOAP it's often much easier to get things right.

This should give us a little better diagnostic ability.  Let's see what happens.  When I try to test it, it just times out, so I can't tell what is happening at that URL.

<?php // demo/mark_06.php
error_reporting(E_ALL);

// http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/PHP/Q_28395751.html

// IF THERE IS A POST-METHOD REQUEST
if (!empty($_POST))
{
    // RETRIEVE VALUES OR ACCEPTABLE DEFAULTS
    $p = !empty($_POST['p']) ? $_POST['p'] : NULL;
    $d = !empty($_POST['d']) ? $_POST['d'] : NULL;

   // CONSTRUCT THE XML DOCUMENT USING HEREDOC SYNTAX
	$xml = <<<ENDXML
<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://www.cisco.com/AXL/API/8.5">

      <ns:addLine sequence="?">

            <pattern>$p</pattern>
            <description>$d</description>
         </line>
      </ns:addLine>
   </soapenv:Body>
</soapenv:Envelope>
ENDXML;

    // MAKE THE cURL CALL HERE
    $url = 'https://192.168.16.245:8443/axl';
    $unm = 'cups';
    $pwd = 'password1';
    $xml = urlencode($xml);
    $res = curl_post($url, $unm, $pwd, $xml, 4);
    echo '<pre>';
    var_dump($res);
}

// IF THERE IS NO POST METHOD REQUEST, CREATE THE FORM
else
{
    $form = <<<ENDFORM
<form method="post">

    echo $form;
}


function curl_post

, $error_report=TRUE
){
    // PREPARE THE CURL CALL
    $curl = curl_init();
    curl_setopt( $curl, CURLOPT_URL,            $url           );
    curl_setopt( $curl, CURLOPT_USERPWD,        $u . ':' . $p  );

    curl_setopt( $curl, CURLOPT_HEADER,         FALSE          );

    curl_setopt( $curl, CURLOPT_ENCODING,       'gzip,deflate' );
    curl_setopt( $curl, CURLOPT_TIMEOUT,        $timeout       );
    curl_setopt( $curl, CURLOPT_RETURNTRANSFER, TRUE           );
    curl_setopt( $curl, CURLOPT_FOLLOWLOCATION, TRUE           );

    // EXECUTE THE CURL CALL
    $htm = curl_exec($curl);
    $err = curl_errno($curl);
    $inf = curl_getinfo($curl);

Thanks for that. I can get it to show the basic HTML page but its still not posting the XML. If I use the CLI with

curl -k -u cups:Nielbazza1! -H "Content-type: text/xml;" -H "SOAPAction: CUCM:DB ver=8.5"  -d @addline.xml https://192.168.16.245:8443/axl/ 

Then it works, where @addline.xml contains exactly the XML in it as above it works. Just trying to workout why this won't convert into PHP.

I have attached the message I am getting...

Sorry, I don't know the CLI well enough to translate it directly into PHP.  Can you tell me if you're using one of the APIs listed on this page?
