我已經在php
上成功上傳圖片的圖片上傳腳本,但現在如果用戶再次上傳了同一個配置文件圖片,我想隨機重命名我有蘭特(1,100000),但它給了我錯誤。在php中隨機重命名相同的上傳配置文件圖片?
我的腳本是在這裏:
<?php
$target_dir = "upload/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
if (file_exists($target_file)) {
$_FILES['file']['name']=rand(1,100000).$_FILES['file']['name'];
$uploadOk = 0;
}
if ($_FILES["fileToUpload"]["size"] > 600000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif") {
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
$uploadOk = 0;
}
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename($_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
\t
\t if (is_file($target_file))
{
echo "Successful<BR/>";
echo "File Name :".$_FILES['fileToUpload']['name']."<BR/>";
echo "File Size :".$_FILES['fileToUpload']['size']."<BR/>";
echo "File Type :".$_FILES['fileToUpload']['type']."<BR/>";
echo "<img src=\"$target_file\" width=\"150\" height=\"150\">";
}
}
?>
而且我得到了以下錯誤:
Warning:move_uploaded_file(88627upload/14316802_10155315964098146_6539510858801534289_n.jpg):未能打開流:在第40行發生的C:\ wamp \ www \ upload \ index2.php中沒有這樣的文件或目錄 –
您正在使用哪個oprationg系統? @RebeccaJoanna –
