File name too long while uploading image in database - php

Question

I have written a line of codes to upload an image in the database, however, trying to upload image gives me this error
File name too long
Following is my code to upload an image to database:
if($_SERVER['REQUEST_METHOD']=="POST")
{
$pid = rand(1000,9000);
$title = $_POST['title'];
$descpt = $_POST['description'];
$push = isset($_POST['send_push']) ? $_POST['send_push'] : "";
$feature_image = array();
$fy = $_POST['fy'];
if(empty($title) || empty($descpt) || empty($fy))
{
array_push($this->errors, MEND_FIELD_ERROR);
return;
}
if(!empty($_FILES['feature_image']['name'][0]))
{
$image = $_FILES['feature_image'];
$allowed_ext = array('jpeg','jpg','png','pdf','docx');
$allowed_size = 20000000;
foreach($image['name'] as $pos=>$image_name)
{
$dir = "./cdn/uploads/notice/".$title;
$tmp = $image['tmp_name'][$pos];
$img_size = $image['size'][$pos];
$img_error = $image['error'][$pos];
$img_ext = explode('.', $image_name);
$img_name = $img_ext[0];
$img_ext = strtolower(end($img_ext));
if(in_array($img_ext, $allowed_ext))
{
if($img_size <= $allowed_size)
{
if(!file_exists($dir))
{
mkdir($dir);
}
$image_new_name = $img_name.'$$'.uniqid('', true).'.'.$img_ext;
$upload_destination = $dir.'/'.$image_new_name;
if(move_uploaded_file($tmp, $upload_destination))
{
array_push($feature_image, $image_new_name);
}
else
{
array_push($this->errors, $img_error);
return;
}
}
}
else
{
array_push($this->errors, $img_ext.' is not an allowed file extension.');
return;
}
}
}
$s_feature_image = json_encode($feature_image, JSON_UNESCAPED_UNICODE);
$statement = $this->db->prepare("INSERT INTO `notice` (`pid`,`title`,`descpt`,`date`,`photo`,`fy`)
VALUES (?,?,?,?,?,?)");
if($statement->execute([$pid,$title,$descpt,DAT, $s_feature_image, $fy]))
{
if($push == "checked")
{
$descpt = strip_tags($descpt);
$tek = array("message"=>$descpt,"title"=>$title);
$tokens = $this->getTokens();
$this->push_notification($tokens,$tek);
}
ExitThis::send_to(URL.'notice?id='.$pid);
}
else
{
array_push($this->errors, DATABASE_ERROR);
return;
}
}
Is it because of permission issue or something else? If so, what is causing me this problem and how do I fix this?

Answer 1

this is how I upload the file into the server and save the file name + extension into the database.
<?php
include 'connection.php';
$id = $_POST['id'];
$imgFile = $_FILES['photo']['name'];
$tmp_dir = $_FILES['photo']['tmp_name'];
$imgSize = $_FILES['photo']['size'];
$folder = 'images/'; // upload directory
$imgExt = strtolower(pathinfo($imgFile, PATHINFO_EXTENSION)); // get image extension
// valid image extensions
$valid_extensions = array('jpeg', 'jpg', 'png', 'gif'); // valid extensions
// rename uploading image
$img = rand(1000, 1000000) . "." . $imgExt;
// allow valid image file formats
if (in_array($imgExt, $valid_extensions)) {
// Check file size '5MB'
if ($imgSize < 5000000) {
move_uploaded_file($tmp_dir, $folder . $img);
} else {
$errMSG = "Sorry, your file is too large.";
}
} else {
$errMSG = "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
}
$query = mysqli_query($con, "UPDATE `profile` SET `photo` = '$img' WHERE `id` = '$id'");
if ($query) {
echo "<script>alert('Profile Updated'); window.location ='index.php?data=profile' </script>";
} else {
echo "<script>alert('Failed'); window.location ='index.php?data=profile' </script>";
}
?>
Hope this helps.
Cheers.
