With code below I am getting two errors..

1. I tried to all

Answer 1

Fo the first error, the errors array is outside the foreah so you doesn't clear the error for each file, and the query to insert is outside the if that checks errors so is always ecexcuted

For the second error the same, the query is executed always you have to check if the file is uploaded.

<?php

    include_once('connect.php');

    if(isset($_FILES['files'])){
        $filesErrors = 0;
        foreach($_FILES['files']['tmp_name'] as $key => $tmp_name ){
            // MOved errors inside the foreach to clear it each loop
            $errors = array();

            // Check file is uploaded
            if ($_FILES['files']['error'][$key] == UPLOAD_ERR_NO_FILE){
                // Continue with the next file
                continue; 
            }

            $file_name = $key.$_FILES['files']['name'][$key];
            $file_size = $_FILES['files']['size'][$key];
            $file_type = $_FILES['files']['type'][$key];

            if($file_type == "image/gif"){
                $sExt = ".gif";
            } elseif($file_type == "image/jpeg" || $file_type == "image/pjpeg"){
                $sExt = ".jpg";
            } elseif($file_type == "image/png" || $file_type == "image/x-png"){
                $sExt = ".png";
            }
            if (!in_array($sExt, array('.gif','.jpg','.png'))) {
                $errors[] = "Image types alowed are (.gif, .jpg, .png) only!";
            }

            $file_tmp = $_FILES['files']['tmp_name'][$key];
            $file_type = $_FILES['files']['type'][$key];
            if($file_size > 2097152){
                $errors[]='File size must be less than 2 MB';
            }    


            if(empty($errors) == true){
                $desired_dir = "user_data";
                // Execute query inside the errors check
                $query = "INSERT into offers_pics (`offer_id`,`pic_name`,`pic_type`) VALUES ('$user_id','$file_name','$file_type'); ";
                $result = mysqli_query($link,$query);

                if(is_dir($desired_dir) == false){
                    mkdir("$desired_dir", 0700);        // Create directory if it does not exist
                }
                if(is_dir("$desired_dir/".$file_name) == false){
                    move_uploaded_file($file_tmp,"$desired_dir/".$file_name);
                }else{                                  // rename the file if another one exist
                    $new_dir = "$desired_dir/".$file_name.time();
                     rename($file_tmp,$new_dir) ;               
                }
            }else{
                $filesErrors++;
                print_r($errors);
            }
        }

        if ($filesErrors == 0){
            echo 'Success';
        }
    }
?>
