Post the html form. why not test if $_POST['txtStartDate'] is set? Make sure to react accordingly if txtStartDate and textEndDate are not set by either sending back an error message or throwing an exception. — busypeoples

Are you sure in your html form, the input elements have a name attribute? Its hard to help without the HTML code, but that's my shot in the dark — Ayush

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

submit = type btnSubmit = name of the button

you are absolutely right isset($_POST["submit"]) will not work because he used "btnSubmit" and not submit

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.

if(isset($_POST['txtStartDate']) && isset($_POST['txtEndDate'])) { $startDate = $_POST['txtStartDate']; $endDate = $_POST['txtEndDate']; echo $startDate; echo $endDate; } This works thank you !!

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']))

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.

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.

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

@MertMETİN Are you sure you are performing a post request? Please show your html.

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']))
