问题
我想删除一个文件AJAX/PHP
。
但是php说我用AJAX发送的文件名不是文件,但是当我直接转到链接时,我可以删除文件。查看我当前的 PHP,我已放入 IF/ELSE 语句以检查字符串是否为带有: 的文件is_file
,结果为false
.
没有is_file
说这个:
Warning: unlink("image.jpg") [function.unlink]: Invalid argument in C:\wamp\www\images\users\delete.php on line 8
调用 ajax 的文件位于我要删除的文件所在的文件夹中。
PHP的
<?php
// I save the file sources from the URL what was sent by AJAX to these variables.
$photo_id = $_GET['photo_id'];
$thumbnail_id = $_GET['thumbnail_id'];
function deletePhotos($id){
// If is a file then delete the file.
if(is_file($id)){
return unlink($id);
// Else show error.
} else {
echo $id . " is not a file, or there is a problem with it.<br />" ;
}
}
if(isset($photo_id)){
deletePhotos($photo_id);
}
if(isset($thumbnail_id)){
deletePhotos($thumbnail_id);
}
?>
阿贾克斯
function deletePhoto(photo, thumbnail){
var photos = encodeURIComponent(photo);
var thumbnails = encodeURIComponent(thumbnail);
if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
} else {// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState==4 && xmlhttp.status==200) {
document.getElementById("media").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET", "http://192.168.2.104/images/users/delete.php?photo_id=\""+photos+"\"&thumbnail_id=\""+thumbnails+"\"", true);
xmlhttp.send();
}
