here's my php insert logic code
if (isset($_POST['create-course']))
{
$img_folder = "../uploads/images/";

if(!file_exists($img_folder))
{
mkdir($img_folder,0777,true);
file_put_contents($img_folder."index.php", "<?php //silence");
file_put_contents("../uploads/index.php", "<?php //silence");

elseif(!file_exists($videos_folder))
{
mkdir($videos_folder,0777,true);
file_put_contents($videos_folder."index.php", "<?php //silence");
}
$current_time = time();
$instructor_id = $_POST['instructor_id'];
$course_title = mysqli_real_escape_string($connect, htmlentities($_POST['course_title']));
$course_description = mysqli_real_escape_string($connect, htmlentities($_POST['course_description']));
$course_details = mysqli_real_escape_string($connect, htmlentities($_POST['course_details']));
$course_image = $current_time.$_FILES['course_image']['name']; (Line 154)
$course_video = $current_time.$_FILES['course_video']['name']; (line 155)
//validate image
$image_allowed = ['image/jpeg','image/jpg','image/png'];
$img_type = $_FILES['course_image']['type']; (Line 159)
//validate video
$video_allowed = ['video/mp4','video/avi','video/3gp','video/mov','video/mpeg'];
$video_type = $_FILES['course_video']['type']; (Line 163)
$check_image = in_array($img_type, $image_allowed);
$check_video = in_array($video_type, $video_allowed);
if($check_image) // check file extension
{
if ($check_video)
{
$query = "INSERT INTO courses (user_id,course_title,course_description,course_details,course_image,course_video) VALUES ('$instructor_id','$course_title','$course_description','$course_details','$course_image','$course_video')";
$query_run = mysqli_query($connect, $query);
if ($query_run)
{
$img_tmp = $_FILES['course_image']['tmp_name'];
$destination = $img_folder.$current_time.$_FILES['course_image']['name'];
move_uploaded_file($img_tmp, $destination);
$video_tmp = $_FILES['course_video']['tmp_name'];
$vid_dst = $videos_folder.$current_time.$_FILES['course_image']['name'];
move_uploaded_file($img_tmp, $vid_dst);
$_SESSION['success'] = "Data Inserted Successfully.";
redirect('../my-courses.php');
}
else
{
$_SESSION['error'] = "Operation failed!";
redirect('../courses-add.php');
}
}
elseif(!$check_video)
{
$_SESSION['vid_error'] = "Only videos of type .mp4, .avi, .3gp, .mov, .mpeg are allowed.";
redirect('../courses-add.php');
}
}
elseif(!$check_image)
{
$_SESSION['img_error'] = "Only images of type .jpg, .jpeg, .png are allowed.";
redirect('../courses-add.php');
}
}
I'll glad if anyone can tell me why, my code isn't running.
