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 class="BBtextInputFrontend">
<input class="BBTextBoxFront" placeholder="placeholder">
<input class="BBInitialValue BBData" type="text" name="BBInitialValue[]">
</div>
</div>
<!-- the rest is the default woocommerce billing inputs -->
<div class="col2-set" id="customer_details">
<div class="col-1">
<div class="woocommerce-billing-fields">
<h3>Billing Details</h3>
<input type="file" name="CheckoutImageUpload">
永远不会在$_FILES数组中返回值。实际上，$_FILES数组总是返回一个空数组。我可以通过$_POST获取其他值而没有任何问题。但不是文件。将插件放在另一台独立计算机上进行全新安装会产生完全相同的结果。
我目前正在使用此代码查找值：
function add_image($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);
任何人都可以帮忙吗？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，同时保留重要的部分。

您的文件名称属性为name="checkoutupload"，但您在整个代码中使用$_FILES['CheckoutImageUpload']。
因此，为了防止您将所有$_FILES['CheckoutImageUpload']更改为指定属性，只需将文件名属性更改为name="CheckoutImageUpload"。
还要确保您上传的文件夹具有正确的路径，并且具有相应的写入权限。
答案 1 :(得分：4)
var_dump($_FILES);以进行调试$_FILES['yourFieldName']['error']是否存在文件上传错误。 php存储['errors'] fwrite ($testLog , "added files: " . $_FILES);不会工作var_dump应该在大多数情况下都能正常工作。 （用于静默调试使用递归foreach循环）$_FILES['yourFieldName']['error']中遇到错误，大部分时间文件大小都是大（php.ini）或文件夹不可写尝试以下方法：
function add_image($order_id) {
//var_dump($_FILES);
$errors = array();
if (
!isset($_FILES['CheckoutImageUpload']['error']) ||
is_array($_FILES['CheckoutImageUpload']['error'])
) {
$errors[] = 'Invalid file.';
}
switch ($_FILES['CheckoutImageUpload']['error']) {
case UPLOAD_ERR_OK:
break;
case UPLOAD_ERR_NO_FILE:
$errors[] = 'you sent no file';
case UPLOAD_ERR_INI_SIZE:
case UPLOAD_ERR_FORM_SIZE:
$errors[] = 'file too big'
default:
$errors[] = 'unknown error';
}
// check filesize manually
if ($_FILES['CheckoutImageUpload']['size'] > 50000) { // whatever your php.ini says
$errors[] = 'file too big';
}
return json_encode($errors);
}
还可以尝试使用小文本文件进行开发。如果大文件失败，请增加这些php.ini值：

我简化并首先测试一个简单的文件上传
这是一个示例。将其保存为test_upload.php并直接通过您的Web服务器访问它以测试文件上传。
<?php
// test_upload.php
// Tests php file upload capabilities
if($_SERVER['REQUEST_METHOD'] == 'POST') {
echo "<pre>";
print_r($_FILES);
exit();
}
?>
<form enctype="multipart/form-data" method='post' action=''>
<input type='file' name='file' />
<input type='submit' value='submit form' />
</form>
如果这不起作用，则需要检查php.ini并确保配置的临时目录可由Web服务器写入。
您可以通过运行以下命令找到系统的临时目录：
php -B 'echo sys_get_temp_dir(); echo "\n"; exit();'
答案 3 :(得分：0)
你是否完全转储$ _FILES？ 也许你有一个具有相同表单名称的其他字段。 如果您已经发布了complet表单，那将更容易（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入权限，然后什么都不返回。 检查服务器日志。 它可能会告诉你发生了什么。
我想到的其他东西。 使用Crome并检查已触发的请求。 但是，请确保您使用网络部分中的复选框来保持会话。 您的浏览器可能会重新加载页面而不会识别它。 ：）
答案 4 :(得分：0)
由于这是一个ajax方法，您需要添加一个ajax方法来上传文件，因为设置略有不同。我认为这种表现会很差，但看看你的想法！
您需要检查脚本中的一些内容 1.我认为我已经使用了正确的表格形式（classname =“checkout”）检查输出的html以确保这是正确的 2.这只适用于页面上的1个文件上传，如果你需要缩小它，可以修改jQuery（文档） 3. Ajaxurl - 阅读代码中的注释，我建议您在尝试脚本之前先检查一下
jQuery(form.checkout).on('submit', function(){
var fd = new FormData();
//searches the whole document, i am assuming you only need 1 file uploaded
var file = jQuery(document).find('input[type="file"]');
var individual_file = file[0].files[0];
fd.append("imagefile", individual_file);
fd.append('action', 'upload_image');
jQuery.ajax({
type: 'POST',
url: ajaxurl, // nb-----------------have you got a variable for ajaxurl? if not insert var ajaxurl = '<?php echo admin_url('admin-ajax.php'); ?>'; somewhere in your template...or google the wp way!
data: fd,
contentType: false,
processData: false,
success: function(response){
//just spit out the response to the console to catch php errors etc..
console.log(response);
}
});
});
在你的functions.php中......
function upload_image(){
echo 'action had been called';
var_dump($_FILES);
// work with files!
}
add_action('wp_ajax_upload_image', 'upload_image');
add_action('wp_ajax_nopriv_upload_image', 'upload_image');
