PHP:发布使用'WebForm_DoPostBackWithOptions'和cUrl的ASPX表单

Question

我正在尝试发布一个使用SharePoint和PHP的ASPX表单. 发布数据与标准表单一起使用,我似乎无法使此表单正常工作.我确实注意到onclick提交按钮上的一个属性:

onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$PlaceHolderMain$btnSaveTask", "", true, "", "", false, false))"

我从未使用ASPX,也不知道这是什么.这不是一个身份验证问题或url的错误,因为它返回网页(包含表单)很好.

这是我的PHP代码:

function add($username, $password){

    $data = array(
        'ctl00$PlaceHolderSearchArea$ctl01$ctl00' => 'https://keystone.stpeters.sa.edu.au',
        'ctl00$PlaceHolderSearchArea$ctl01$ctl04' => '0',
        'ctl00$PlaceHolderMain$DateStart$DateStartDate' => '9/05/2012',
        'ctl00$PlaceHolderMain$DateDue$DateDueDate' => '10/05/2012',
        'ctl00$PlaceHolderMain$Title' => 'test again',
        'ctl00$PlaceHolderMain$btnSaveTask' => 'OK',
        '__spText1' => '',
        '__spText2' => ''
    );

    $curl_handle = curl_init();
    $fullurl = "https://keystone.stpeters.sa.edu.au/_layouts/StPeters.Keystone/MyTasks/MyTaskDetail.aspx?id=0&IsDlg=1"; // 
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_VERBOSE, 1);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_FAILONERROR, 0);
    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
    curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
    curl_setopt($ch, CURLOPT_URL, $fullurl);

    $returned = curl_exec($ch);

    curl_close ($ch);

    return $returned;
}
