我的程序本应在目录中为上传的图像创建一个文件夹,但给出了以下警告:
mkdir()[function.mkdir]:文件存在于C:''XAMP''examplep''htdocs''gallery''uploader3.php的第26行
这是代码:
<html>
<head>
<title> Sample1 - File Upload on Directory </title>
</head>
<body>
<div align="center">
<form action="uploader3.php" method="post" enctype="multipart/form-data" >
<input type="hidden" name="MAX_FILE_SIZE" value="100000" />
Create an Album (limited to 10 images): <br />
<input type="file" name="uploadedfile[]" /><br />
<input type="file" name="uploadedfile[]" /><br />
<input type="file" name="uploadedfile[]" /><br />
<input type="file" name="uploadedfile[]" /><br />
<input type="file" name="uploadedfile[]" /><br />
<input type="file" name="uploadedfile[]" /><br />
<input type="file" name="uploadedfile[]" /><br />
<input type="file" name="uploadedfile[]" /><br />
<input type="file" name="uploadedfile[]" /><br />
<input type="file" name="uploadedfile[]" /><br />
<br />
<input type="submit" value="Upload File" />
</form>
</div>
<?php
$target_path = "uploads1/";
if(!mkdir($target_path))
{
die('Failed to create folders...');
}
else
{
for($count = 0; $count < count($_FILES['uploadedfile']); $count++)
{
$target_path = $target_path . basename( $_FILES['uploadedfile']['name'][$count]);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'][$count], $target_path))
{
echo "The file ". basename( $_FILES['uploadedfile']['name'][$count]).
" has been uploaded";
}
else{
echo "There was an error uploading the file, please try again!";
}
}
}
?>
</body>
</html>
修改以下代码:
if(!mkdir($target_path))
{
die('Failed to create folders...');
}
至:
if(!file_exist($target_path)) {
if(!mkdir($target_path))
{
die('Failed to create folders...');
}
}
这将首先检查文件夹,如果它已经存在,则无需再次创建。
对于你的第二个问题,你需要将上传的图像名称存储到某个地方(我想DB是一个不错的选择),然后,你可以在任何你想要的地方显示它们。或者您可以使用以下代码在文件夹中搜索并显示它们:
$image_files = glob("uploads1/*.jpg");
foreach($image_files as $img) {
echo "<img src='".$img."' /><br/>";
}
在尝试创建之前,您应该首先检查目录是否不存在
if (!file_exists($target_path))
mkdir($target_path);
if (file_exists($target_path))
{
// Further processing here
}
else
{
// Could not create directory
}
