Question

我已经设置了一个更新数据库的脚本，所有表单字段都可以工作，包括文件上传，它确实上传到我的服务器，我的问题是我希望图像的url出现在mysql表中，所以我可以在以后引用它（它与该条目相关联，但我尝试的所有内容都不想添加它。任何想法？

这是我的表格

<fieldset style="width:300px;">
<form method="post" action="./upload.php" enctype="multipart/form-data">>
Desc <input type="text" name="holdesc1"><br>
Dest <input type="text" name="holdest1"><br>
RRP <input type="text" name="rrp1"><br>
Cost Per <input type="text" name="cpe1"><br>
Entries Avail <input type="text" name="ea1"><br>
<label for="file">Select a file:</label> <input type="file" name="userfile" id="file">
<br>
<input type="submit" name="submit">
</form>
</fieldset>

这是我的上传脚本

Answer 1

在代码中没有文件名字段。

$filename=mysql_real_escape_string($_POST['filename']); // this field is not in form

您有名称为userfile的输入类型文件，因此您需要使用此字段，如

$userfile = $_FILES['userfile']['name'];  // this field is in form

其次，您应该将文件上传代码移到isset($_POST)。

第三次尝试使用mysqli_ *函数
