我的文件上传时出现此问题。我在检查验证时尝试上传我的PDF文件TMP_NAME
为空,当我检查$_FILES['document_attach']['error']
时,值为1,这意味着错误。
但是当我尝试上传其他PDF文件时,它已成功上传。为什么其他PDF文件没有?
HTML
<form action="actions/upload_internal_audit.php" method="post" enctype="multipart/form-data">
<label>Title</label>
<span><input type="text" name="title" class="form-control" placeholder="Document Title"></span>
<label>File</label>
<span><input type="file" name="document_attach"></span><br>
<span><input type="submit" name="submit" value="Upload" class="btn btn-primary"></span>
</form>
PHP
if(isset($_POST['submit'])){
$title = $_POST['title'];
$filename = $_FILES['document_attach']['name'];
$target_dir = "../eqms_files/";
$maxSize = 5000000;
if(!empty($title)){
if(is_uploaded_file($_FILES['document_attach']['tmp_name'])){
if ($_FILES['document_attach']['size'] > $maxSize) {
echo "File must be: ' . $maxSize . '";
} else {
$result = move_uploaded_file($_FILES['document_attach']['tmp_name'], $target_dir . $filename);
mysqli_query($con, "INSERT into internal_audit (id, title, file) VALUES ('', '".$title."', '".$filename."')");
echo "Successfully Uploaded";
}
}else
echo "Error Uploading try again later";
}else
echo "Document Title is empty";
}
答案 0 :(得分:42)
我只是检查phpinfo();
中的最大尺寸然后检查php.ini是否已加载
$inipath = php_ini_loaded_file();
if ($inipath) {
echo 'Loaded php.ini: ' . $inipath;
} else {
echo 'A php.ini file is not loaded';
}
然后更改upload_max_filesize=2M to 8M
; Maximum allowed size for uploaded files.
upload_max_filesize = 8M
; Must be greater than or equal to upload_max_filesize
post_max_size = 8M
答案 1 :(得分:6)
var_dump($_FILES['file_flag']['tmp_name']); // file_flag file key
will return empty string
array (size=1)
'course_video' =>
array (size=5)
'name' => string 'fasdfasdfasdfsd.mp4' (length=19)
'type' => string '' (length=0)
'tmp_name' => string '' (length=0) <===== *** this point
'error' => int 1
'size' => int 0
这是因为WAMP服务器不接受这么大的规模来上传到服务器上。
为避免这种情况,我们需要更改php.ini文件。
upload_max_filesize=100M (as per your need)
post_max_size = 100M (as per your need)
终于重启服务器
