php - Function mod_scorm_insert_scorm_tracks "Invalid parameter" -
i have problem webservice function moodle callen "mod_scorm_insert_scorm_tracks"
this function used inserting track information (i.e. star time) of user in scorm progress.
part of estructure of function
scoid= int attempt= int tracks[0][element]= string tracks[0][value]= string new php structe has this
[tracks] => array ( [0] => array ( [element] => string [value] => string ) ) i have used 1 of examples had in website fine until got error
<b>notice</b>: array string conversion in <b>c:\xampp\htdocs\otros\php-rest\curl.php</b> on line <b>247</b><br /> <?xml version="1.0" encoding="utf-8" ?> <exception class="invalid_parameter_exception"> <errorcode>invalidparameter</errorcode> <message>invalid parameter value detected</message> <debuginfo>tracks => invalid parameter value detected: arrays accepted. bad value is: 'array'</debuginfo> </exception> and problem seems here:
$item1 = new stdclass(); $item1->scoid = '2'; $item1->attempt = '1'; $item1->tracks = array( array( array( 'element' => 'x.start.time', 'value' => '1473102672' ), ), array( array( 'element' => 'x.start.time', 'value' => '1473102680' ), ), ); i tried in many ways
$item1 = new stdclass(); $item1->scoid = '2'; $item1->attempt = '1'; $item1->tracks = array('element' => 'x.start.time','value' => '1473102672'); or
$item1 = new stdclass(); $item1->scoid = '2'; $item1->attempt = '1'; $item1->tracks = array(array ('element' => 'x.start.time','value' => '1473102672')); and still getting same message, i'm pretty problema wyntax have tried in many ways , still not working hope yo can me.

well after research took plan b
i wrote tracks in different variable:
$tracks = array(); $tracks[] = array( 'element' => 'cmi.core.lesson_status', 'value' => 'completed' ); and followed curl.php array set option:
$arrayname = array('' => , ); then when inserted scoid , attemps single variables in array:
$params = array('scoid' => '2', 'attempt' => '1', 'tracks' => $tracks); and boala!the record on table:
