1. Modify and set the size of the uploaded file.
2. Add "php_value upload_max_filesize "300M"" to it.
3. Just restart the server.
Using ThinkPhp framework to upload small image files successfully, but failed to upload large files.
Later, I found the reason because PHP restricts the size of uploaded files, and modified the following configuration:
upload_max_filesize = 300M post_max_size = 300M
Restarting the server, it's still the same, the problem has not been resolved.
The solution is as follows, add it as follows:
php_value upload_max_filesize "300M" php_value post_max_size "300M"
Restart the server again, OK!
Knowledge point expansion:
Error handling
The error attribute in the file array is judged:
$error=$myfile['myfile']['error'];
if ($error==0){//It is 0, which means the upload is successful if (move_uploaded_file($tmp,"userpic/".$picname)) {
echo "Moving the file successfully";
}else{
echo "Failed to move files";
}
}else{//Not 0, match error message switch ($error){
case 1:
echo "Exceeding maximum file upload limit";// upload_max_filesize break;
case 2:
echo "Exceed form file size limit";//The MAX_FILE_SIZE option in the HTML form break;
case 3:
echo "The file part is uploaded";
break;
case 4:
echo "Upload file not selected";
break;
case 7://File writing failed case 8:
echo "System Error";
break;
}
}
Upload restrictions
On the front end, you can limit the uploaded file type and size:
<!--The form hidden domain limits upload size--> <input type="hidden" name="MAX_FILE_SIZE" value="2097152"> <!--accept Limitations on file types--> <input type="file" name="myfile" accept="image/jpeg,image/png">
Note that the limit is in bytes
Response restrictions must be made on the server side:
$size=$myfile['size'];//Get file size$MaxSize=2097152;//Set the maximum allowable byte$type=$myfile['type'];//Get picture type$AllowTypr=array('image/jpeg','image/png','image/gif');//Allow type arrayif ($error==0){//It is 0, which means the upload is successful if ($size>$MaxSize){
echo "<script>alert('File size exceeds limit');</script>";
echo "<script>(1);</script>";
exit();
}
if (!in_array($type,$AllowTypr)){
echo "<script>alert('Please upload the correct image type');</script>";
echo "<script>(1);</script>";
exit();
}
