                     </div>
                     <div class="form-group">
                        <label for="exampleFormControlFile1">Left</label>
                        <input type="file" name="vehi_left" class="form-control-file" id="exampleFormControlFile1">
                     </div>
                     <div class="form-group">
                        <label for="exampleFormControlFile1">Right</label>
                        <input type="file" name="vehi_right" class="form-control-file" id="exampleFormControlFile1">
                     </div>
                     <div class="form-group">
                        <label for="exampleFormControlFile1">Rear</label>
                        <input type="file" name="vehi_back" class="form-control-file" id="exampleFormControlFile1">
                     </div>
                     <textarea placeholder="Other" name="other" type="text" class="txt_3"></textarea>
                     <input type="submit" value="submit" name="submit" class="txt2">
                </form>
            </div>
            </div>
            </div>
</div>
</div>

This is the insert query code.

<?php
include("../inc/conn.php");

$brand=$_POST['brand'];
$model=$_POST['model'];
$vehi_front=$_POST['vehi_front'];
$vehi_left=$_POST['vehi_left'];
$vehi_right=$_POST['vehi_right'];
$vehi_back=$_POST['vehi_back'];
$other=$_POST['other'];
    {
    $sql = "INSERT INTO vehicle(brand,model,vehi_front,vehi_left,vehi_right,vehi_back,other) VALUES ('{$brand}','{$model}','{$vehi_front}','{$vehi_left}','{$vehi_right}','{$vehi_back}','{$other}')";
    if(mysqli_query($con,$sql))
    {
    header("location:add_vehicle.php?msg=Successfully Saved !");
    }   
}
?>

Answer 1

You can do this using $_FILES variable

see reference here: https://www.php.net/manual/en/reserved.variables.files.php

Answer 2

you must create image uploader function in php $_POST['image_input_name'] return you null you must use $_FILE

  function uploadPic($file_input_name, $path)
    {
        if (isset($_FILES[$file_input_name])) {
            $file = $_FILES[$file_input_name];
            // for bin2hex and random_bytes you must use php > 7
            $new_name = (string)bin2hex(random_bytes(32));
            $extension = ".jpg";
            $final_name = $new_name . $extension;
            move_uploaded_file($file['tmp_name'], $path . $final_name);
            return $path . $final_name;

        }
    }

first line check for image 2 get the file and put in into $file 3 change the name for security 4 change the extension for more security // user upload a shel.php. in function we change the name and extension // for exp shel.php converted to hs7f4w8r5c1f4s5d9t6g3s149748654asdasd.jpg 5 add name and extension in var 6 we move uploaded pic to path 7 we return the address and name of pic and in your new code here

<?php
include("../inc/conn.php");

$brand = $_POST['brand'];
        $model = $_POST['model'];
        // in if we check for image exist
        if ($_FILES['vehi_front']['tmp_name'] != "") {
            $vehi_front = $this->uploadPic("vehi_front", "/path/to/save/image");
        }
        if ($_FILES['vehi_left']['tmp_name'] != "") {
            $vehi_left = $this->uploadPic("vehi_left", "/path/to/save/image");
        }
        if ($_FILES['vehi_right']['tmp_name'] != "") {
            $vehi_right = $this->uploadPic("vehi_right", "/path/to/save/image");
        }
        if ($_FILES['vehi_back']['tmp_name'] != "") {
            $vehi_right = $this->uploadPic("vehi_back", "/path/to/save/image");
        }


        $other = $_POST['other'];
        {
            $sql = "INSERT INTO vehicle(brand,model,vehi_front,vehi_left,vehi_right,vehi_back,other) VALUES ('{$brand}','{$model}','{$vehi_front}','{$vehi_left}','{$vehi_right}','{$vehi_back}','{$other}')";
            if (mysqli_query($con, $sql)) {
                header("location:add_vehicle.php?msg=Successfully Saved !");
            }
        }
?>
