move_uploaded_file 没有上传图片
move_uploaded_file not uploading image
我正在尝试将文件上传到图像文件夹,并将目录路径插入到 mysql
数据库中。
这是我的 HTML
表格
<form enctype="multipart/form-data" method="post" action="newfacility.php">
<fieldset>
<legend>New Facility</legend>
...
<label for="photo">Facility Photo:</label>
<input type="file" id="facilityphoto" name="facilityphoto" /><br />
<label for="province">Photo Description:</label>
<input type="text" id="photodesc" name="photodesc" /><br />
....
<input type="submit" value="Create" name="submit" />
</fieldset>
</form>
newfacility.php
require_once('../appvars.php');
require_once('upload_image.php');
//connect to db and test connection.
$dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);
if (!$dbc) {
die("Connection failed: " . mysqli_connect_error());
}
if (isset($_POST['submit'])) {
// Grab the user data from the POST
$facilityNumber = mysqli_real_escape_string($dbc, trim($_POST['facilitynumber']));
....
....
//This is defined in appvars.php -- define('MM_UPLOADPATH', 'images/');
//facility photo
$facilityPhoto = MM_UPLOADPATH . basename($_FILES["facilityphoto"]["name"]);
$facilityPhotoDesc = mysqli_real_escape_string($dbc, trim($_POST['photodesc']));
// check if the faciliy info already exists.
if (!empty($facilityNumber) && !empty($facilityName) && !empty($facilityAddress) && !empty($facilityCity)) {
$query = "SELECT * FROM facility WHERE facility_number = '$facilityNumber' AND facility_name = '$facilityName' "
. "AND facility_address = '$facilityAddress' AND facility_city = '$facilityCity'";
$data = mysqli_query($dbc, $query);
//if the facility is unique insert the data into the database
if (mysqli_num_rows($data) == 0) {
//insert into facility table
$query = "INSERT INTO facility (facility_id, account_id, facility_number, facility_name, facility_address,"
. " facility_city, facility_province, facility_postal_code, facility_photo, facility_roof_plan,"
. " facility_roof_size, facility_roof_size_inspected, facility_last_inspected_date, facility_inspected_by)"
. " VALUES (NULL, '$selectedAssocAccount', '$facilityNumber', '$facilityName', '$facilityAddress', "
. "'$facilityCity', '$facilityProvince', '$facilityPostalCode', '$facilityRoofSize', "
. "'$facilityRoofSizeInspected', '$facilityDayInspected', '$facilityInspectedBy')";
mysqli_query($dbc, $query);
//query used to get the facility_id of the facility we had just entered -- I haven't tested this yet.
$getFacilityID = "SELECT facility_id FROM facility WHERE facility_number = '$facilityNumber' AND facility_name = '$facilityName' "
. "AND facility_address = '$facilityAddress' AND facility_city = '$facilityCity'";
$facilityID = mysqli_query($dbc, $getFacilityID);
//insert into photo table
$photoQuery = "INSERT INTO photo (photo_id, facility_id, photo, photo_desc)"
. "VALUES (NULL, $facilityID, $facilityPhoto, $facilityPhotoDesc)";
mysqli_query($dbc, $photoQuery);
// Confirm success with the user
echo '<p>You have succesfully created a new facility. '
. 'Please go back to the <a href="/admin.php">admin panel</a>.</p>';
//testing to see if I can view the image
echo '<img class="profile" src="' . MM_UPLOADPATH . $facilityPhoto . '"/>';
//close db connection
mysqli_close($dbc);
exit();
}
最后是upload_image.php
if(isset($_FILES["facilityphoto"])) {
// Check if file already exists
if (file_exists($facilityPhoto)) {
echo "Sorry, facility photo already exists.";
}
if($_FILES['facilityphoto']['error'] !==0) {
echo "Error uploading facility photo image.";
} else {
if (move_uploaded_file($_FILES["facilityphoto"]["tmp_name"], $facilityPhoto)) {
echo "The file ".( $_FILES["facilityphoto"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading the facility photo.";
}
}
}
所以我现在不断遇到的错误是:echo "Sorry, there was an error uploading the facility photo.";
我不明白我在这里做错了什么导致图像没有上传到我的 images/
目录中。
替换这些行:
if (move_uploaded_file($_FILES["facilityphoto"]["tmp_name"], $facilityPhoto)){
echo "The file ".( $_FILES["facilityphoto"]["name"]). " has been uploaded.";
}
这些:
if (move_uploaded_file($_FILES["facilityphoto"]["tmp_name"], 'images/'. $_FILES["facilityphoto"]["name"])){
echo "The file ".( $_FILES["facilityphoto"]["name"]). " has been uploaded.";
}
我将提供一个仅解决文件上传问题的答案,所有数据库内容都从答案中删除,因为它不相关。
// returns true only if the file was written to $to,
// the value of $status_msg will be a user friendly string
// representing the outcome.
function save_facility_photo($from, $to, &$status_msg) {
// Check if file already exists
if (file_exists($to)) {
$status_msg = "Sorry, facility photo already exists.";
return false;
}
if (move_uploaded_file($from, $to)) {
$status_msg = "The file ".basename($to)." has been uploaded.";
return true;
}
$status_msg = "Sorry, there was an error uploading the facility photo.";
return false;
}
if (isset($_POST['submit'])) {
define('MM_UPLOADPATH', 'images/');
$facilityPhoto = MM_UPLOADPATH . basename($_FILES["facilityphoto"]["name"]);
if ($_FILES['facilityphoto']['error'] == UPLOAD_ERR_OK) {
$status_msg = '';
$from = $_FILES["facilityphoto"]["tmp_name"];
$saved = save_facility_photo($from, $facilityPhoto, $status_msg);
}
else {
// handle upload error
}
// continue with code
}
以下是对我认为在您的脚本中发生的情况的解释。
在newfacility.php
的顶部,调用了require_once('upload_image.php');
。现在让我们一步一步 upload_image.php
注意 $facilityPhoto
还没有被定义
// this is very likely true
if(isset($_FILES["facilityphoto"])) {
// $facilityPhoto is undefined so file_exists(NULL) will return false
if (file_exists($facilityPhoto)) { }
// the image upload was probably successful, so we jump to the else branch
if($_FILES['facilityphoto']['error'] !==0) {
}
else {
// $facilityPhoto is undefined move_uploaded_file('p/a/t/h', NULL)
// will return false, so we jump to the else branch
if (move_uploaded_file($_FILES["facilityphoto"]["tmp_name"], $facilityPhoto)) {
}
else {
// resulting in this error
echo "Sorry, there was an error uploading the facility photo.";
