Question

我正在使用一个简单的表单上传5个文件：

<form enctype="multipart/form-data" action="openaccount.php" method="post">
<h4>Proof of Identity of Account Operator 1</h4>

<p>Government issued Photo ID to verify identity:
<br/><input name="tidentity_proof" type="file" />

<p>Documentation to verify permanent residential address:
<br/><input name="taddress_proof" type="file" />

<h4>Proof of Identity of Account Operator 2 (if any)</h4>

<p>Government issued Photo ID to verify identity:
<br/><input name="tidentity_proof2" type="file" />

<p>Documentation to verify permanent residential address:
<br/><input name="taddress_proof2" type="file" />

<h4>Signed Fund Agreement</h4>
<p>Choose a file to upload:
<br/><input name="tagreement" type="file" />

<input type="submit" name="submit" value="Submit" />

</form>

由于这五个文件中的每一个都是强制性的，我会在提交表单时检查是否已经上传了所有文件：

if($_FILES['tidentity_proof']['name']=="" || $_FILES['tidentity_proof2']['name']=="" || $_FILES['taddress_proof']['name']=="" || $_FILES['taddress_proof2']['name']=="" || $_FILES['tagreement']['name']==""){
    $_SESSION['message'].="You must upload files as identity proof.";
}

如果我为所有5个字段选择文件，前4个工作正常，但第5个工作没有。因此，如果我echo $_FILES['tagreement']['name'];我得到一个空字符串，如果我对所有其他字符串执行相同的操作，则会正确打印出文件名。我在这里缺少什么？

编辑：'tagreement'字段在列表中的最后一个并不重要，我尝试将其移到其他字段之前，但它仍然无法正常工作。

print_r($_FILES)：

Array (
    [tidentity_proof] => Array (
        [name] => cathypersons_deerdoe.jpg
        [type] => image/jpeg
        [tmp_name] => /tmp/phpcfeBC9
        [error] => 0 [size] => 40299
    )
    [taddress_proof] => Array (
        [name] => cheetah20cubs.jpg
        [type] => image/jpeg
        [tmp_name] => /tmp/phpRp4qu1
        [error] => 0 [size] => 84873
    )
    [tidentity_proof2] => Array (
        [name] => cheetah20cubs.jpg
        [type] => image/jpeg
        [tmp_name] => /tmp/phpCpGkmT
        [error] => 0
        [size] => 84873
    )
    [taddress_proof2] => Array (
        [name] => cathypersons_deerdoe.jpg
        [type] => image/jpeg
        [tmp_name] => /tmp/phpBUBheL
        [error] => 0
        [size] => 40299
    )
)

在显示中看起来像您的字段名称，并且检查中的变量名称不一致。

你的第二段代码应该是：

if($_FILES['tidentity_proof']['name']=="" || $_FILES['taddress_proof']['name']=="" || $_FILES['tidentity_proof2']['name']=="" || $_FILES['taddress_proof2']['name']=="" || $_FILES['tagreement']['name']==""){
    $_SESSION['message'].="You must upload files as identity proof.";
}

文件上传不能以HTML格式运行
