未定义的索引和函数没有运行

Question

我有类似这样的代码来启动脚本来发送订单。

include('../../auto/util.php');
if (!isValidFileName($_FILES['file-1']['tmp_name']) | !isValidFileName($_FILES['file-2']['tmp_name']))
{
    echo "Invalid filename, <a href='index.php'>try again</a>.";
}
else if (count($_FILES) === 0)
{
    echo "Your files failed to upload, likely because together they exceeded 15MB. Please submit the order manually to <a href=\"mailto:abc123@abc123.com\">abc123@abc123.com</a>";
}
else
{
    newOrder_broker();
}

如果有文件上传，我会收到 file-1 和 file-2 的未定义索引错误。如果没有文件上传但代码有效并根据需要注入订单，我会得到同样的错误。

我的 HTML 看起来像这样：

<form id="docContainer" enctype="multipart/form-data" method="POST" action="newOrder_broker.php"

HTML 中的提交看起来像这样：

      <div id="fb-submit-button-div" class="fb-item-alignment-left">
    <button class="fb-button-special" id="fb-submit-button" style="background-image: url(theme/default/images/btn_submit.png);" onclick="checkShipTo();">Submit</button>
  </div>

如果没有文件，我不希望进程停止。

表格HTML代码：

<body onload="checkCustoms()">
<!-- Start of the body content for CoffeeCup Web Form Builder -->

<?php  include("alert.php"); ?>

<form id="docContainer" enctype="multipart/form-data" method="POST" action="newOrder_broker.php"
class="fb-100-item-column fb-toplabel selected-object" style="" data-form="manual_iframe">

<!-- // lots of form fields here here -->

  <br />

            <div id="item17" class="fb-item fb-50-item-column" style="opacity: 1; ">
            <div class="fb-grouplabel">
              <label id="item17_label_0" style="display: inline; ">
                Upload front (Maximum size: 15MB)
              </label>
              <input type="checkbox" class="saveCheck" id="file-1-check" />
            </div>
            <div class="fb-button">
              <input type="file" id="file-1" data-hint="" name="file-1-upload" onchange="readURL(this);" />
            </div>
            <br />
            <img id="file-1-upload" src="#" alt="Preview (front)" width="200"/>
          </div>



          <div id="item31" class="fb-item fb-50-item-column" style="opacity: 1; ">
            <div class="fb-grouplabel">
              <label id="item31_label_0" style="display: inline; ">
                Upload back (Maximum size: 15MB)
              </label>
              <input type="checkbox" class="saveCheck" id="file-2-check" />
            </div>
            <div class="fb-button">
              <input type="file" id="file-2" data-hint="" name="file-2-upload" onchange="readURL(this);" />
            </div>
            <br />
            <img id="file-2-upload" src="#" alt="Preview (back)" width="200" />
          </div>


  <div id="fb-submit-button-div" class="fb-item-alignment-left">
    <button class="fb-button-special" id="fb-submit-button" style="background-image: url(theme/default/images/btn_submit.png);" onclick="checkShipTo();">Submit</button>
  </div>
  <button type="reset" onclick="localStorage.clear(); location.reload();">Reset</button>
  <input type="hidden" name="fb_form_custom_html" />
  <input type="hidden" name="fb_form_embedded" />
</form>

好的，所以我将名称更改为 "file-1" 和 "file-2"。我也添加了数组位置 [0] 但仍然得到：

Notice: Undefined index: file-1 in /home/prima2go/public_html/broker/sdp/newOrder_broker.php on line 6

    Notice: Undefined index: file-2 in /home/prima2go/public_html/broker/sdp/newOrder_broker.php on line 6
    Your files failed to upload, likely because together they exceeded 15MB. Please submit the order manually to abc123@primaatlanta.com

    <input type="file" id="file-1" data-hint="" name="file-1" onchange="readURL(this);" />

一个

if (!isValidFileName($_FILES['file-1'][0]['tmp_name']) | !isValidFileName($_FILES['file-2'][0]['tmp_name']))

Answer 1

您的表单缺少 "file" 类型的输入。输入应如下所示：

<input type="file" value="">

如果没有这些输入，您的 PHP 将不会设置 $_FILES 数组，因此会出现您遇到的错误。

更新：

现在我看到了你所有的表格，我注意到你的文件输入是这样的：

<input type="file" id="file-1" name="file-1-upload" />
<input type="file" id="file-2" name="file-2-upload" />

这意味着您需要使用 name 属性通过 PHP 访问这些内容，如下所示：

 $_FILES['file-1-upload']['tmp_name']
 $_FILES['file-2-upload']['tmp_name']
