Undefinded index: satuan in insertstoragedata.php

Question

I'm new in PHP and I'm getting this error:

Undefinded index: satuan in D:\xampp\htdocs\Belajar\data\insertstoragedata.php on line 11

I couldn't find any solution online, so maybe someone can help me.

Here is the code:

$satuan             =   $_POST['satuan'];

thats the 11 line,can anyone help me??? I really can't understand why

Answer 1

Try this

if(isset($_POST['satuan'])){
    $satuan = $_POST['satuan'];
} else{
    $satuan = '';
}

Answer 2

Try some thing like this

<form action="insertstoragedata.php" method="post">
    <input type="text" name="satuan">
    <input type="submit" value="submit">
</form>

In insertstoragedata.php

$satuan = $_POST['satuan'];

Note: make sure name="" is correct. Its Case Sensitive

And possible duplicate of PHP: "Notice: Undefined variable" and "Notice: Undefined index"

Answer 3

You can try something like this..

$satuan  = (isset($_POST['satuan']) ? $_POST['satuan'] : null);
