App Inventor图像和文本表单到SQL无法正常工作

Question

我们正在使用App发明者2创建一个APP，它通过PHP脚本将包含文本字段和2个图像的表单提交到mySQL数据库。我们制作了一个HTML表单来测试它运行正常，但不幸的是我们的应用程序发明者块在提交表单时似乎没有用。这是我的街区图片的链接;

这是我的PHP脚本;

<?php
                    // database connection
                    mysql_connect(localhost, username, password) OR DIE (mysql_error());

                    // select the db
                    mysql_select_db (outofhours) OR DIE ("Unable to select db".mysql_error());

$maxsize = 10000000; //set to approx 10 MB

$sitename = $_POST['sitename'];
$siteaddress = $_POST['siteaddress'];
$sitepostcode = $_POST['sitepostcode'];
$eqmake = $_POST['eqmake'];
$eqmodel = $_POST['eqmodel'];
$eqdesc = $_POST['eqdesc'];
$eqserial = $_POST['eqserial'];
$eqassetno = $_POST['eqassetno'];
$eqconttype = $_POST['eqconttype'];
$brewery = $_POST['brewery'];
$date = $_POST['date'];
$onsitetime = $_POST['onsitetime'];
$offsitetime = $_POST['offsitetime'];
$custprintname = $_POST['custprintname'];
$custposition = $_POST['custposition'];
$engname = $_POST['engname'];

// check if a file was submitted
if(!isset($_FILES['engsig1']))
{
    echo '<p>Please select a file</p>';
}
else
{
    try {
    $msg= upload();  //this will upload your image
    echo $msg;  //Message showing success or failure.
    }
    catch(Exception $e) {
    echo $e->getMessage();
    echo 'Sorry, could not upload file';
    }
}
