Hi I need to take a list of folder name to my database how can I do that?

I code like that but it takes only the last data from folder list. what is wrong?

Also I want : if there is same project name. it doesnt get it twice and give me alert for " Already exsist that name"


What I have tried:


 if($_POST["action"] == "fetch")

 $connect = mysqli_connect("localhost", "root", "Pasword", "folder");

  $folder = array_filter(glob('aaa/*'), 'is_dir');

   foreach($folder as $name)

    $sql = "INSERT INTO folder (folder_name)  VALUES ('$name')   ";  
    if(mysqli_query($connect, $sql))

Your foreach and if statements are incomplete.

What is the correct form of the code?

You need to learn the language properly: PHP: foreach - Manual[^].

Here is learning and helping platform I think... if I know or I can learn from anywhere else : so why we are talking here about that?

I wrote down here to learn already...

So please if you dont answer about how to code or how can I solve the problem with excat codes.. Dont write down my question.. Thanks

You cannot learn a programming language by posting questions here. You need to study it in detail before you even think of writing code.

And the answer you are looking for is something like the following:
foreach($folder as $name)
    $sql = "INSERT INTO folder (folder_name)  VALUES ('$name')   ";  
    if(mysqli_query($connect, $sql)) 
        // so if the sql call succeeds, you need to do something with the data
        // and if it fails - then what?
} // and this is the end of the foreach

Thanks.. And you can belive in that, I am trying to learn coding but not from book. My style is like that:

I need something that I know what will I do...and now researching internet about how can I do thoses...

so with that way I am learning when I do what I needs.
I only ask when I really cant do that, if u can see that: this is my first question... BUt I did what I need half of them

And probably the very worst way to do it. Unless you understand the complete language you are relying on code that could have been written by anyone, who may not fully understand what they are doing.
Haluk Aydogan 18-Apr-20 3:58am
Yes I think you are right... Maybe both need .. First try to do something from internet and than I think I must read book. so When I am reading book I can understand more... you are right really.

$sql = "INSERT INTO folder (folder_name)  VALUES ('$name')   ";

Your code is almost certainly vulnerable to SQL Injection[^]. NEVER use string concatenation to build a SQL query. ALWAYS use a parameterized query.

PHP: SQL Injection - Manual[^]

First of all thanks... Secondly, can you please write down what I must not do and what I must do clearly?

PHP: Prepared statements and stored procedures - Manual[^]
PHP: mysqli::prepare[^]
PHP: mysqli_stmt::bind_param[^]
$connect = mysqli_connect("localhost", "root", "Pasword", "folder");
$stmt = $mysqli_prepare("INSERT INTO folder (folder_name)  VALUES (?)");
mysqli_stmt_bind_param($stmt, 's', $folder_name);

$folder = array_filter(glob('aaa/*'), 'is_dir');
foreach($folder as $name) {
    $folder_name = $name;
