Как сохранить путь к изображению в базе данных в MySQL для PHP

Я сохранил данные в базе данных для загрузки файлов, но я не могу сохранить их в базе данных mysql. Я сохранил загруженное изображение в нужном месте, но я хочу знать, как сохранить путь изображения в базе данных. Код HTML:

</head>
<form action="file_upload.php" method="POST" enctype="multipart/form-data">
<table>
<tr>
<td>
Name of Applicant:
</td>
<td>
<input type="text" width="40px" name="nm"/>
</td>
</tr>
<br/>
<tr>
<td>
Email-Id:
</td>
<td>
<input type="text" width="40px" name="email"/>
</td>
</tr>
<br/>
<tr>

<td>
mobile:
</td>
<td>
<input type="number" width="30px" name="mobile"/>
</td>
</tr>
<br/>
<tr>
<td>
Resume:</td>
<td>
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Upload File" name="submit">
</td>
</tr>


</table>
</form>

PHP-код:

<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 50000000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
$con=mysql_connect("localhost","root","");
mysql_select_db("db1",$con);
mysql_query("insert into reg_job values('".$_POST["nm"]."','".$_POST["email"]."','".$_POST["mobile"]."')");
echo "Record inserted";

mysql_close($con);
?>
