[英]move_uploaded_file - file name of image?
劇本:
<?php
if (isset($_POST['submit'])) {
$j = 0; //Variable for indexing uploaded image
$target_path = "uploads/"; //Declaring Path for uploaded images
for ($i = 0; $i < count($_FILES['file']['name']); $i++) {//loop to get individual element from the array
$validextensions = array("jpeg", "jpg", "png"); //Extensions which are allowed
$ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.)
$file_extension = end($ext); //store extensions in the variable
$target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext) - 1];//set the target path with a new name of image
$j = $j + 1;//increment the number of uploaded images according to the files in array
if (($_FILES["file"]["size"][$i] < 100000) //Approx. 100kb files can be uploaded.
&& in_array($file_extension, $validextensions)) {
if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {//if file moved to uploads folder
echo $j. ').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';
} else {//if file was not moved.
echo $j. ').<span id="error">please try again!.</span><br/><br/>';
}
} else {//if file size and file type was incorrect.
echo $j. ').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
}
}
}
?>
該腳本還使用javascript來上傳多個圖像。
該腳本可以正常工作,但是當多個文件移入“上載”文件夾時,文件名如下所示:
"2f594262c1f8fb56c39cc01d4543bcb9.jpg"
"2f594262c1f8fb56c39cc01d4543bcb9.jpgf00008a16882f01d2bd7ed6d9805a4bf.jpg"
"2f594262c1f8fb56c39cc01d4543bcb9.jpgf00008a16882f01d2bd7ed6d9805a4bf.jpge967f7fbaea4e2aee9b6f56067739aed.jpg"
如何解決這個問題?
在for循環中重置$target_path
。 現在,您只是不斷地添加它。
for ($i = 0; $i < count($_FILES['file']['name']); $i++) {//loop to get individual element from the array
$target_path = "uploads/"; //Declaring Path for uploaded images
