【问题描述】:
我有一个可以上传图片的表单。但是由于某种原因,我无法上传图像。我已经更新了文件权限(777 权限),但文件仍然没有上传。该表单似乎正在工作,因为文本(未包含在表单中正在更新)
<form action="manage_content.php?project=5" method="post" enctype="multipart/form-data">
<div class="width">
<p>Project Image: <br>
<input type="file" name="image_file" id="file" class="inputfile" />
<label for="file">Choose a file</label>
</p>
</div>
<input type="submit" name="update_project" value="Update Current Project">
</form>
PHP 表单处理。
if (isset($_POST['update_project'])) {
$required_fields = array("project_name", "date", "content");
validate_presences($required_fields);
$fields_with_max_length = array("project_name" => 30);
validate_max_length($fields_with_max_length);
$id = $current_project["id"];
$project_name = mysql_prep($_POST["project_name"]);
$date = mysql_prep($_POST["date"]);
$content = mysql_prep($_POST["content"]);
$target_dir = "images/";
$target_file = $target_dir . basename($_FILES["image_file"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
print_r($_FILES);
echo "<br>" . $target_file;
if (empty($errors)) {
if($_FILES["image_file"]["error"] == 4) {
//means there is no file uploaded
$query = "";
$result = mysqli_query($connection, $query);
if ($result && mysqli_affected_rows($connection) >= 0) {
$_SESSION["message"] = "Subject Updated";
// redirect_to("manage_content.php?subject=$current_subject[id]");
}
} else {
$query = "";
$result = mysqli_query($connection, $query);
if ($result && mysqli_affected_rows($connection) >= 0) {
$_SESSION["message"] = "Subject Updated";
// redirect_to("manage_content.php?subject=$current_subject[id]");
}
}
} else {
$message = "Subject creation failed.";
}
} else {
// probably a get request
// end of post submit
}
?>
print_r($_FILES) 给我:
Array ( [image_file] => Array (
[name] => 1.jpg
[type] => image/jpeg
[tmp_name] => C:\xampp\tmp\phpF5AA.tmp
[error] => 0
[size] => 24397 )
)
and echo $target_file gives: images/1.jpg
【问题讨论】:
-
将上传的文件移动到文件夹的代码在哪里?
-
您遇到错误了吗?你的日志是怎么说的?
-
谢谢你解决了。 :)
