[英]php file upload with validation type
在PHP中,我有上传文件的代码是这样的
$image_name= $_FILES['file']['name'];
$allowedExts = array("gif", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["file"]["name"]);
$extension = end($temp);
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/jpg")
|| ($_FILES["file"]["type"] == "image/pjpeg")
|| ($_FILES["file"]["type"] == "image/x-png")
|| ($_FILES["file"]["type"] == "image/png"))
&& in_array($extension, $allowedExts)) {
if ($_FILES["file"]["error"] > 0) {
echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
}
else {
move_uploaded_file($_FILES['file']['tmp_name'], $tmpName.$image_name);
}
}
现在,当我执行上传时,此代码可以正常工作。 但这不适用于文件类型验证。 我已经使用$allowedExts = array("gif", "jpeg", "jpg", "png"); to use only these types of file to upload. But this one is uploading any files type. So can someone kindly tell me where is the wrong part here. I want to upload only
$allowedExts = array("gif", "jpeg", "jpg", "png"); to use only these types of file to upload. But this one is uploading any files type. So can someone kindly tell me where is the wrong part here. I want to upload only
$allowedExts = array("gif", "jpeg", "jpg", "png"); to use only these types of file to upload. But this one is uploading any files type. So can someone kindly tell me where is the wrong part here. I want to upload only
“ gif”,“ jpeg”,“ jpg”,“ png”文件。 任何帮助和建议将是非常宝贵的。 谢谢。
我记得以前我遇到过文件类型问题,但无法解决,所以我决定继续进行其他工作。 这是我检查上传的文件之前是否为“图像”的方法之一。 我认为检查文件是否实际上是图像的好方法并不多,但实际上它对我有用,到那时我什么也没想到。
<?php
if(isAnImage($routetoyourfile)) {
//Move the file
} else {
//Delete it
}
function isAnImage($fileroute) {
$ext = pathinfo($fileroute, PATHINFO_EXTENSION);
if($ext != "jpg" && $ext != "jpeg" && $ext != "png" && $ext != "JPG" && $ext != "PNG" && $ext != "JPEG") {
return 0;
} else {
return 1;
}
}
?>
