结账时$ _FILES为空

Cap*_*ndo 10 php wordpress woocommerce

我在woocommerce的结帐表单中添加了一堆新字段.它读取完成的php文件;

    <form name="checkout" method="post" class="checkout woocommerce-checkout processing" action="http://localhost:100/wordpress/checkout/" enctype="multipart/form-data" style="position: relative; zoom: 1;">
        <div id="pagePreview">
            <input type="file" name="CheckoutImageUpload">     
            <div class="BBtextInputFrontend">
                <input class="BBTextBoxFront" placeholder="placeholder">
                <input class="BBInitialValue BBData" type="text" name="BBInitialValue[]">
            </div>

            </div>
        </div>

        <!-- the rest is the default woocommerce billing inputs -->

            <div class="col-1">

问题是输入

<input type="file" name="CheckoutImageUpload">
Run Code Online (Sandbox Code Playgroud)

永远不会返回$_FILES数组中的值.实际上,$_FILES数组总是返回一个空数组.我可以毫无问题地获得其他价值$_POST.但不是文件.将插件放在另一台单独的计算机上进行全新安装会产生完全相同的结果.

我目前正在使用此代码来查找值:

function add_image($order_id) {
    //if they DID upload a file...

    if ($_FILES['CheckoutImageUpload']['name']) {
        ?>Y<?php
        die();
    }
    else {
        ?>N<?php
        die();
    }
}
add_action( 'woocommerce_checkout_update_order_meta', 'add_image', 100, 1);

有人可以帮忙吗？我觉得我正在失去理智

我在下面添加了完整的代码.你在上面看到的是缩短它,同时保留重要部分.

您的文件的名称属性是name="checkoutupload"您在$_FILES['CheckoutImageUpload']整个代码中使用的.

因此,为了防止您将所有$_FILES['CheckoutImageUpload']命名属性更改为命名属性,只需将文件名属性更改为name="CheckoutImageUpload".

还要确保要上载的文件夹具有正确的路径,并且具有写入该文件夹的适当权限.

你完全转储$_FILES了吗？也许您还有其他具有相同表单名称的字段。如果您发布了完整的表格，那就会更容易（如前所述）。另一个原因可能是，您的 php 堆栈没有对上传文件夹的写权限，然后不返回任何内容。检查您的服务器日志。它可能会告诉你发生了什么。

我刚刚想到的其他事情。使用 Crome 并检查已触发哪些请求。但请确保突出显示网络部分中的复选框以保留会话。您的浏览器可能会在您不认识的情况下重新加载页面。:)
