我有以下代码，用于从两个输入上传两个文件。（没有倍数）。
问题是，如果一个文件是正确的，而另一个文件不是，例如一个是.jpg，另一个是.exe，则上载.jpg而不上载.exe。
我如何编辑我的代码，以便如果两个文件中至少有一个不正确，则不会上传任何内容并显示相应的消息？
如果两个文件都正常，则继续上载。
消息：1。文件2太大。没有有效的扩展
$valid_formats = array("jpg", "gif", "zip", "bmp", "pdf", "doc", "docx");
$max_file_size = 1024*300; //100 kb
$path = "uploads/"; // Upload directory
$count = 0;
// Loop $_FILES to execute all files
foreach ($_FILES['files']['name'] as $f => $name) {
if ($_FILES['files']['size'][$f] > $max_file_size) {
header("Location: http://www.");
}
elseif( ! in_array(pathinfo($name, PATHINFO_EXTENSION), $valid_formats) ){
header("Location: http://www.");
}
else{ // No error found! Move uploaded files
$random = rand(1,30);
if(move_uploaded_file($_FILES["files"]["tmp_name"][$f], $path.$random.$name)) {
$count++; // Number of successfully uploaded files
header("Location: http://www.");
}
}
}
您需要在一个单独的循环中完成：
$valid_formats = array("jpg", "gif", "zip", "bmp", "pdf", "doc", "docx");
$max_file_size = 1024*300; //100 kb
$path = "uploads/"; // Upload directory
$count = 0;
foreach ($_FILES['files']['name'] as $f => $name)
{
if ($_FILES['files']['size'][$f] > $max_file_size)
{
header("Location: http://www.");
exit();
}
elseif( ! in_array(pathinfo($name, PATHINFO_EXTENSION), $valid_formats) )
{
header("Location: http://www.");
exit();
}
}
// Loop $_FILES to execute all files
foreach ($_FILES['files']['name'] as $f => $name)
{
$random = rand(1,30);
if(move_uploaded_file($_FILES["files"]["tmp_name"][$f], $path.$random.$name))
{
$count++; // Number of successfully uploaded files
header("Location: http://www.");
}
}
move_uploaded_file应该在for each之外。循环一次以确保所有内容都有效，第二次则实际移动上传。
如果原始循环有任何错误，则不应运行第二个循环
