Greetings to all who stumble upon my post. In general, there is an HTML form for creating a new topic on the forum, the user can add a name, a description, and if he wants a photo. I want to achieve that, even if the user does not select an image, you can add everything else without downloading images. At the moment, after you click Submit, and even if the images are not selected, empty files are still loaded into db. Here is my code:
<div class="main col-md-9 col-md-offset-3"> <center><h2>Start New Topic</h2></center> <form accept-charset="UTF-8" action="" method="POST" enctype="multipart/form-data"> <div class="form-group"> <label>Title*</label> <input type='text' class="form-control" id="title" name='title' value='' maxlength="155" required> <h6 class="pull-right" id="count_title"></h6> </div> <div class="form-group"> <label for="sel1">Category</label> <select class="form-control" id="sel1"> <option>none</option> <option>Movies</option> <option>Politics</option> <option>Celebreties</option> <option>Music</option> <option>Books</option> <option>Various</option> </select> </div> <div class="form-group"> <label>Include Description</label> <textarea class="form-control" id="description" name='description' cols='60' rows='10' maxlength="5550"></textarea> <h6 class="pull-right" id="count_description"></h6> </div> <div class="form-group"> <label>Include Images</label> <input type="file" name="files[]" multiple="" /> </div> <div class="form-group pull-right"> <input type='submit' class="btn btn-info btn-md" name='submit' value='Go!'> </div> </form> PHP script:
//if form has been submitted process it if(isset($_POST['submit'])){ $_POST = array_map( 'stripslashes', $_POST ); //collect form data extract($_POST); //basic validation if($title ==''){ $error[] = 'Please enter the title.'; } if(!isset($error)){ try { $title = htmlspecialchars($title); $description = htmlspecialchars($description); //insert into database $stmt = $db->prepare('INSERT INTO topics (title,description,date_started) VALUES (:title, :seotitle, :description, NOW())'); $stmt->execute(array( ':title' => $title, ':seotitle' => $seotitle, ':description' => $description )); $last_id = $db->lastInsertId(); //inserting images if(isset($_FILES['files'])){ $errors= array(); foreach($_FILES['files']['tmp_name'] as $key => $tmp_name ){ $file_name = 'loorha_'.$user_id.'_'.$last_id.'_'.$key.$_FILES['files']['name'][$key]; $file_size =$_FILES['files']['size'][$key]; $file_tmp =$_FILES['files']['tmp_name'][$key]; $file_type=$_FILES['files']['type'][$key]; if($file_size > 2000000){ $errors[]='File size must be less than 2 MB'; } //Storing Images into DB $stmt = $db->prepare('INSERT INTO topics_images (topic_id,user_id,img_name,size,type,time_uploaded) VALUES ("'.$last_id.'","'.$user_id.'","'.$file_name.'", "'.$file_size.'", "'.$file_type.'",NOW())'); $stmt->execute(); $destinationFolder ="uploads/topic/$last_id"; if(empty($errors)==true){ if(is_dir($destinationFolder)==false){ mkdir("$destinationFolder", 0700); // Create directory if it does not appear in the root folder } if(is_dir("$destinationFolder/".$file_name)==false){ $file_name = $destinationFolder. "/".$file_name; move_uploaded_file($file_tmp, $file_name); }else{ //rename the file if another one exist $new_dir="$destinationFolder/".$file_name.time(); rename($file_tmp,$new_dir) ; } }else{ print_r($errors); } } if(empty($error)){ echo "Images Uploaded Successfully!"; } } //redirect to just created topic header('Location: topic/' . $last_id . '/' . $seotitle); exit; } catch(PDOException $e) { echo $e->getMessage(); } } } I tried to do this with if(isset($_FILES['files'])){ but still, it does not work correctly. I will be glad to any advice or help! Thank!
