使用PHP上传文件不会上传到服务器

Question

我正在尝试在我的库存系统上运行文件上传，但似乎无法使其正常运行。我正在使用Lite Uploader和PHP。

这是我的upload.php文件：

<?php
require('../../includes/config.php');

$urls = array();

if (isset($_POST['liteUploader_id']) && $_POST['liteUploader_id'] == 'fileUpload1'){

foreach ($_FILES['fileUpload1']['error'] as $key => $error){
    if ($error == UPLOAD_ERR_OK){
        $uploadedUrl = $var['site_url'].'assets/images/uploads/' . $_FILES['fileUpload1']['name'][$key];
        move_uploaded_file( $_FILES['fileUpload1']['tmp_name'][$key], $uploadedUrl);
        $urls[] = $uploadedUrl;
    }
}

if(file_exists($uploadedUrl)){
    $message = "Successfully uploaded file.";
} else {
    $message = "File did not upload properly.";
}

}

echo json_encode(
array(
    'message' => $message,
    'urls' => $urls,
)
);
exit;

?>

暂时上传文件时似乎没有移动，因为上传时Chrome上没有显示图片。

如果您需要任何其他文件，请告知我们。非常感谢！

编辑：

以下是上传表单代码：

<input type="file" name="fileUpload1" id="fileUpload1" class="fileUpload" />
<div id="details"></div>
<div id="response"></div>
<div id="previews"></div>

表单通过javascript完成，代码如下：

jQuery('.fileUpload').liteUploader({
    script: 'libraries/lite_uploader/upload.php',
    allowedFileTypes: 'image/jpeg,image/png,image/gif',
    maxSizeInBytes: 250000,
    customParams: {
        'custom': 'tester'
    },
    before: function (files)
    {
        jQuery('#details, #previews').empty();
        jQuery('#response').html('Uploading ' + files.length + ' file(s)...');
    },
    each: function (file, errors)
    {
        var i, errorsDisp = '';

        if (errors.length > 0)
        {
            jQuery('#response').html('One or more files did not pass validation');

            jQuery.each(errors, function(i, error)
            {
                errorsDisp += '<br /><span class="error">' + error.type + ' error - Rule: ' + error.rule + '</span>';
            });
        }

        jQuery('#details').append('<p>name: ' + file.name + ', type: ' + file.type + ', size:' + file.size + errorsDisp + '</p>');
    },
    success: function (response)
    {
        var response = jQuery.parseJSON(response);

        jQuery.each(response.urls, function(i, url)
        {
            jQuery('#previews').append(jQuery('<img>', {'src': url, 'width': 200}));
        });

        jQuery('#response').html(response.message);
    }
});
