我收到错误：
Notice: Undefined index: file_upload in ..\admin\addproduct.php on line 48
Notice: Undefined index: in ..\admin\addproduct.php on line 49
这是：
if(move_uploaded_file($tmp_file, $upload_dir."/".$target_file) && move_uploaded_file($tmp_file1, $upload_dir."/".$target_file1)) {
$product->create();
$message = "Product uploaded successfully. <br />";
} else {
echo "<pre>".print_r($_FILES,true)."</pre>";
$error = $_FILES['file_upload']['error'];
$message = $upload_errors[$error];
}
当我使用echo“
".print_r($_FILES,true)."”时; 我明白了：
阵 （ [img1] =＆gt;排列 （ [name] =＆gt; IMG_6527.JPG [type] =＆gt; [tmp_name] =＆gt; [错误] =＆gt; 2 [size] =＆gt; 0 ）
[img2] => Array
(
[name] =>
[type] =>
[tmp_name] =>
[error] => 4
[size] => 0
)
)
请帮帮我..
谢谢..
答案 0 :(得分：1)
您的文件存储在img2数组中的$_FILES下，而不是file_upload下。
所以你的行必须是
$error = $_FILES['img2']['error'];
那是因为您在此处为$_FILES数组提供了索引名称name
<td align='left'><input name='img2' type='file' /></td>
您必须检查文件是否上传为答案中提到的moeed-farooqui。
如果是可选的
if(isset($_FILES['img2'])){
// only do something if a file is uploaded
}
或者如果需要
if(isset($_FILES['img2'])){
// handle the uploaded file
} else {
// genereate an error message cause no file was uploaded
}
答案 1 :(得分：0)
使用isset来设置值是否设置
if(isset($_FILES['xyz'])){
// your code here
}
除此之外，我找不到名称为file_upload的任何字段。
应该是：
$error = $_FILES['img2']['error'];
