php - 为什么我上传的数据被重命名，并且相应的数据被添加到不同的行？

Question

当我向数据库中插入数据时，数据提交成功，但我不知道如何显示“成功”消息，通知我数据已发送成功；我只需要假设它已成功提交。

然后，当我在数据库中检查它时，数据就在那里，但不是我想要的方式。假设我上传了图片 spongebob.png 并且发送到数据库的图片是 15-04-2015-1429064604.png，并且图片和数据对应于该图像被插入到单独的行中，数据位于图像上方的行中......不知道为什么。

我希望图片名称与我上传的图片相同，并且与其他数据在同一行。

我得到的截图:

这是我的 HTML:

<form action="insert_backend.php" method="POST" enctype="multipart/form-data">
<!-- Method can be set as POST for hiding values in URL-->
<h2>Form</h2>
<label for="uploadedimage">Small image to upload: </label>
<input type="file" name="uploadedimage" id="uploadedimage"/><br />
<label>Date:</label>
<input class="input" name="date" type="text" value=""><br />

<input class="input" name="retrace" type="text" value=""><br />

<label>Trading Instrument:</label>
<input class="input" name="trading_instrument" type="text" value=""><br />
<input class="submit" name="submit" type="submit" value="Insert">
</form>

这是我的 PHP:

<?php
/**********MYSQL Settings****************/
$host="";
$databasename="";
$user="";
$pass="";
/**********MYSQL Settings****************/

error_reporting(E_ALL);
ini_set('display_errors', 1);

$conn=mysql_connect($host,$user,$pass);

if($conn)
{
$db_selected = mysql_select_db($databasename, $conn);
if (!$db_selected) {
    die ('Can\'t use foo : ' . mysql_error());
}
}
else
{
    die('Not connected : ' . mysql_error());

     }

if (!empty($_FILES["uploadedimage"]["name"])) {

        $query_upload="INSERT into charts ( charts_URL ) VALUES ('".$target_path."')";
	mysql_query($query_upload) or die("error in $query_upload == ----> ".mysql_error());  
	
}else{

   echo("Error While uploading image on the server");
} 

}
?>
<?php
if(isset($_POST['submit'])){ // Fetching variables of the form which travels in URL
$date = $_POST['date'];

$query_upload = "INSERT into charts (charts_date, charts_retrace, charts_start_of_swing_trade, charts_end_of_swing_trade, charts_bullflag, charts_bearflag, charts_ema_crossover, charts_trading_instrument) VALUES ('$date', '$retrace', '$start_of_swing_trade', '$end_of_swing_trade', '$bull_flag', '$bear_flag', '$ema_crossover', '$trading_instrument')";
mysql_query($query_upload) or die("error in $query_upload == ----> ".mysql_error());  
	
}else{

   echo("Data sent successfully!");
} 
}
mysql_close($conn); // Closing Connection with Server
?>

我对上述PHP代码所做的新改动:

图片上传代码

if (!empty($_FILES["uploadedimage"]["name"])) {

	$file_name=$_FILES["uploadedimage"]["name"];
	$temp_name=$_FILES["uploadedimage"]["tmp_name"];
	$imgtype=$_FILES["uploadedimage"]["type"];
	$ext= GetImageExtension($imgtype);
	$imagename=$_FILES['uploadedimage']['name'];
	$target_path = "images/".$imagename;
	

if(move_uploaded_file($temp_name, $target_path)) {

        $query_upload="INSERT INTO charts ( charts_URL ) VALUES ('".$target_path."')";  
	
}

$result =  mysqli_query($conn, $query_upload);
if ($result)
{
 echo "success, image has been inserted successfully";
}
else
{
 die("Error: " . $sql . "<br>" . mysqli_error($conn);
}

图片上传按钮下方的数据插入代码

if($date !=''||$trading_instrument !=''){
//Insert Query of SQL
$query_upload = "INSERT into charts (charts_date, charts_retrace, charts_start_of_swing_trade, charts_end_of_swing_trade, charts_bullflag, charts_bearflag, charts_ema_crossover, charts_trading_instrument) VALUES ('$date', '$retrace', '$start_of_swing_trade', '$end_of_swing_trade', '$bull_flag', '$bear_flag', '$ema_crossover', '$trading_instrument')";
	
}
$result =  mysqli_query($conn, $query_upload);
if ($result)
{
 echo "success, data has been inserted successfully";
}
else
{
 die("Error: " . $sql . "<br>" . mysqli_error($conn);
}

Answer 1

When I Insert data into the database, the data submits successfully but I have no idea how to get a "Success" message to display informing me that the data has been sent successfully.

$result =  mysqli_query($connection, $query);
if ($result)
{
 // use echo "success, data has been inserted successfully or create a success page and redirect to another page from here
}
else
{
 // query fails
}

I can upload the image spongebob.png and the image that gets sent to the database is 15-04-2015-1429064604.png. I want the image name to be the same as the image I uploaded.

$_FILES['uploadedimage']['name'] will give you the original image name.

在你的代码中，你正在这样做，

$imagename=date("d-m-Y")."-".time().$ext; // you are adding date, time and extension of the image.
$target_path = "images/".$imagename;

所以，喜欢

$imagename= $_FILES['uploadedimage']['name']; // `$imagename` will now contain spongebob.png
$target_path = "images/".$imagename; // images/spongebob.png

重要:

`mysql_*` is deprecated. Migrate it to `mysqli_*` or `PDO`. You code is vulnerable to SQL Injection.
