PHP文件上传什么都不做
我以前有过几个上传表单,但是,即使在几乎复制了我以前的代码之后,这个似乎也不起作用,我更喜欢在一个php脚本文件中完成这一切,所以它都是在这个文件中生成的 我的表格:PHP文件上传什么都不做,php,forms,file,upload,Php,Forms,File,Upload,我以前有过几个上传表单,但是,即使在几乎复制了我以前的代码之后,这个似乎也不起作用,我更喜欢在一个php脚本文件中完成这一切,所以它都是在这个文件中生成的 我的表格: <form action="" method="post" enctype="multipart/form-data"> <ul> <li> <label for="file">File : </label>

当我上传一个.png图像时,页面似乎只是在刷新,我已经放置了找到的回音。;在那里检查它在$\u POST[file]中是否有任何内容,但它似乎没有任何内容
我不明白为什么页面提交不正确。我已将action=更改为action=upload.php,以确保它指向相同的页面,但仍然没有任何内容。使用$\u FILES['file']而不是$\u POST['file']
阅读有关$\u文件的更多信息,请访问将$\u POST['file']替换为$\u FILES['file'],并设置action=。尝试以下操作。。。。因为$\u POST不能处理文件,所以对于文件,我们使用$\u文件
if(!empty($_FILES['file']))
{
echo "Found.";
$exts = array("gif", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["file"]["name"]);
$ext = end($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"))
&& ($_FILES["file"]["size"] < 20000)
&& in_array($ext, $exts))
{
if($_FILES["file"]["error"] > 0)
{
$result = "Error Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
$scandir = scandir("/images/news/");
$newname = (count($scandir-2)) . $ext;
move_uploaded_file($_FILES["file"]["tmp_name"],"/images/news/" . $newname);
$ulink = "/images/news/" . $newname;
$result = "Success, please copy your link below";
}
}
else
{
$result = "Error.";
}
}
我不会只检查$\u FILES变量。我将命名提交输入并检查提交输入是否已提交。通过这种方式,您可以检查按钮是否在未选择任何文件的情况下按下,并提示用户 像这样:
<form action="" method="post" enctype="multipart/form-data">
<ul>
<li>
<label for="file">File : </label>
<input type="file" id="file" name="file" required="required" />
</li>
<li>
<input type="submit" value="Upload" name="upload"/>
</li>
</ul>
</form>
if(!empty($_POST['upload']))
{
echo "Found.";
$exts = array("gif", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["file"]["name"]);
$ext = end($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"))
&& ($_FILES["file"]["size"] < 20000)
&& in_array($ext, $exts))
{
if($_FILES["file"]["error"] > 0)
{
$result = "Error Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
$scandir = scandir("/images/news/");
$newname = (count($scandir-2)) . $ext;
move_uploaded_file($_FILES["file"]["tmp_name"],"/images/news/" . $newname);
$ulink = "/images/news/" . $newname;
$result = "Success, please copy your link below";
}
}
else
{
$result = "Error.";
}
}
然后可以检查post变量的值
像这样:
<form action="" method="post" enctype="multipart/form-data">
<ul>
<li>
<label for="file">File : </label>
<input type="file" id="file" name="file" required="required" />
</li>
<li>
<input type="submit" value="Upload" name="upload"/>
</li>
</ul>
</form>
if(!empty($_POST['upload']))
{
echo "Found.";
$exts = array("gif", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["file"]["name"]);
$ext = end($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"))
&& ($_FILES["file"]["size"] < 20000)
&& in_array($ext, $exts))
{
if($_FILES["file"]["error"] > 0)
{
$result = "Error Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
$scandir = scandir("/images/news/");
$newname = (count($scandir-2)) . $ext;
move_uploaded_file($_FILES["file"]["tmp_name"],"/images/news/" . $newname);
$ulink = "/images/news/" . $newname;
$result = "Success, please copy your link below";
}
}
else
{
$result = "Error.";
}
}
