Subject:    [SOAP] size limit for message sub-nodes?

Hello,

I have defined a SOAP message for submitting mixed data, including a base64 encoded \
image.  Everything works fine when the images I send are small (640x480).  However \
when my images grow too large (1024x768), the image data coming out of the SOAP \
request appears to be truncated.  For example, instead of being 169,048 bytes, it is \
166,448 bytes.

What I'm doing is re-encoding the image data that SoapServer has decoded for me for \
the purpose of storing it in a text field in a mysql table.  So it may be that \
SoapServer is truncating the data.  Or (less likely?) it may be that base64_encode is \
truncating the data.

Is there a size limit for message sub-nodes that SoapServer can handle?

I have attached relevant sections of my server and WSDL file below.


Thanks in advance for any advice.

Brian


Here are the relevant parts of my SOAP server:

<?php

function submitSighting($collector_id, 
	 		$species_common_name, 
			$sighting_datetime,
			$location_lat,
			$location_long,
			$notes = NULL,
			$alive_flag = true,
			$photovideo = NULL) {

  $species_common_name = mysql_real_escape_string($species_common_name);
  $sighting_datetime = mysql_real_escape_string($sighting_datetime);
  $location_lat = mysql_real_escape_string($location_lat);
  $location_long = mysql_real_escape_string($location_long);
  if (NULL != $notes) {
    $notes = mysql_real_escape_string($notes);
  } else {
    $notes = "";
  }
  if (true == $alive_flag) {
    $alive_flag = 'Y';
  } else {
    $alive_flag = 'N';
  }
  if (NULL != $photovideo) {
    $photovideo = base64_encode($photovideo);
  } else {
    $photovideo = "";
  }

  $species_id = getSpeciesIdFromCommonName($species_common_name, $link); // function \
definition removed from this snippet  if (!$species_id) {
     $msg =  "The species " . $species_common_name . " is unknown.";
  }

  // Insert into the sightings table
  $query = sprintf("insert into pws_sightings values (NULL, %d, %d, 'N', '%s', %f, \
%f, '%s', '%s', '%s')",  $collector_id, 
		   $species_id,
		   $sighting_datetime,
		   $location_lat,
		   $location_long,
		   $notes,
		   $alive_flag,
		   $photovideo);

  $result = mysql_query($query);
  if ($result) {
     $msg = "Success"; 
  } else {
     $msg .= " was NOT successfully submitted due to error: " . mysql_error(); 
  }

  error_log($msg, 0);

  return $msg;
}

// SOAP stuff
ini_set("soap.wsdl_cache_enabled", "1"); // Enable WSDL cache
$server = new SoapServer("pws.wsdl");

$server->addFunction("submitSighting");

$server->handle();

?>


Here is the relevant excerpt from my WSDL file:

<message name='submitSightingRequest'>
  <part name='collector_id' type='xsd:integer'/>
  <part name='species_common_name' type='xsd:string'/>
  <part name='sighting_datetime' type='xsd:dateTime'/>
  <part name='location_lat' type='xsd:double'/>
  <part name='location_long' type='xsd:double'/>
  <part name='notes' type='xsd:string'/>

  <part name='photovideo' type='xsd:base64Binary'/>
</message>
