if(!isset($_POST['submit']))

This means that if the submit button was NOT pressed. You should check if the $_POST['submit'] is set, as a result of the form submission, like so:

if(isset($_POST['submit']))

I guess it should be if(isset($_POST['submit'])) instead of if(!isset($_POST['submit'])) as ! in the start means a negation

You have to use isset() on every variable, not just one variable. $_POST['txtStartDate'] and $_POST['txtEndDate'] and other variables are simply not defined, this means that they were not sent with the POST request.

It must be isset($_POST["btnSubmit"]) NOT submit

submit = type btnSubmit = name of the button

I think it should be:

if(isset($_POST['submit']))

instead of:

if(!isset($_POST['submit']))

The exclamation mark in front of isset means not. Also I would check for the actual fields you want to use, not for $_POST['submit']:

if(isset($_POST['txtStartDate']) && isset($_POST['txtEndDate']))
{
    // Do something with $_POST['txtStartDate'] and $_POST['txtEndDate']
}

The reason you were getting the error is that $_POST['submit'] does not exist. There is not input element with a name attribute called submit. Beware of the difference between type and name.

When your page is loading and $_POST['submit'] is not set, your $_POST['txtStartDate'] and $_POST['txtEndDate'] are not set so $arrDates is not set too. You need to check if these $_POST vars are set or not, to work with them.

Undefined index txtStartDate, ...

It seems that your form may not be conforming to the same variable name specification with the one that you use in this php file. Make sure field names are matching within the form and here.

And also you should make these checks in your php file after submission success: if(!isset($_POST['submit']))
