这是我第一次尝试通过PHP上传文件。
这是我的HTML:
<form role="form" action="api/upload.php" id="uploadForm" method="post" enctype="multipart/form-data">
<input id="fileToUpload" name="fileToUpload" type="file" class="file" />
<button type="submit" name="submit" id="submit">Upload</button>
</form>
现在这里是PHP脚本参考&#34; api / upload.php&#34;:
<?php
$target_dir = "files\\";
if(isset($_POST["submit"])) {
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
}
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
if ($_FILES["fileToUpload"]["size"] > 500000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
if ($uploadOk == 0) {
echo $uploadOk . "Sorry, your file was not uploaded.";
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["name"], $target_file)) {
echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else{
echo "Sorry, there was an error uploading your file.";
}
}
?>
这可能是一个逻辑错误。我不确定。无论如何,我不断收到消息:
抱歉,上传文件时出错
当我回显$ uploadOk时,它仍然是1.如何找到我的错误?
答案 0 :(得分:0)
使用$_FILES["fileToUpload"]["tmp_name"]
代替$_FILES["fileToUpload"]["name"]
应该是
move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file);
注: -
$_FILES["fileToUpload"]["name"]
只是上传文件的名称。 $_FILES["fileToUpload"]["tmp_name"]
是保存内容的临时文件。
希望这有帮助。

我在按钮上添加value="submit"
属性时出错了。对于name="submit"
检查,isset($_POST["submit"))
属性就足够了。
