私は「mod_scorm_insert_scorm_tracks」のMoodleキャレンのためのWebサービス機能に問題があるこの関数は、彼のSCORMの進行中の利用者のトラック情報（すなわち、スター時間）を挿入するために使用される機能mod_scorm_insert_scorm_tracks「無効なパラメータが」
。この機能のestructureの
一部は
scoid= int
attempt= int
tracks[0][element]= string
tracks[0][value]= string
NEW PHPのstructeは、私は彼らが持っていた例の一つを使用していたこの
[tracks] =>
Array
(
[0] =>
Array
(
[element] => string
[value] => string
)
)
に見えるように持っています彼のウェブサイトはこのエラーが出るまでうまくいった。
<b>Notice</b>: Array to 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: Only arrays accepted. The bad value is: 'Array'</DEBUGINFO>
</EXCEPTION>
そして、問題はここにあると思われる：
$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'
),
),
);
私は多くの方法で
$item1 = new stdClass();
$item1->scoid = '2';
$item1->attempt = '1';
$item1->tracks = array('element' => 'x.start.time','value' => '1473102672');
または
$item1 = new stdClass();
$item1->scoid = '2';
$item1->attempt = '1';
$item1->tracks = array(array ('element' => 'x.start.time','value' => '1473102672'));
そして、まだ同じメッセージを取得を試みたが、私はよかなり私のwyntaxとproblemaですが、私は多くの方法で試して、まだ動作していない私はヨウが私を助けることを願っています。
