Error to validate the start date and end date in php file

Question

When we declare the java script the validation not applied and not fired an error wile the is same as input type i have declared the code in php file.

I have used Xammp server, running MySQL 5, PHP 7.6.2 and Apache 2.

<script  type="text/javascript">
    //Validation for Stratdate & Enddate for New Ticket creation form                       

    $("#tedate").change(function () {

        var objFromDate = document.getElementById("tsdate").value; 
        var objToDate = document.getElementById("tedate").value;

        var FromDate = new Date(objFromDate);
        var ToDate = new Date(objToDate);

        if(FromDate > ToDate )
        {
            alert("Due Date Should Be Greater Than Start Date");
            document.getElementById("tedate").value = "";
            return false; 
        }

    });
</script>

start date

<input type='date' id="tsdate" class="form-control col-md-6"  placeholder="mm-dd-yyyy" name="startdate">

due date

<input type='date' id="tedate" class="form-control col-md-6" placeholder="Enter Due Date" name="enddate" required />

_"Yes is working fine i will also try in another file that works"_? So the posted code works? Then what is your issue? I'm a bit confused here. — M. Eriksson, Apr 03 '19 at 05:36

Use strtotime function in php


if(strtotime($date1) < strtotime($date2)){
      /* Code */
}

Use getTime() function which will convert the time into epoch format.For more details visit https://www.epochconverter.com/programming/#javascript

you can do the following to check in the frontend.

Javascript

  $(".data-controller").change(function () {
        var objFromDate = document.getElementById("tsdate").value;
        var objToDate = document.getElementById("tedate").value;

        var FromDate = (new Date(objFromDate).getTime()) / 1000;
        var ToDate = (new Date(objToDate).getTime()) / 1000;

        if (FromDate > ToDate) {
            alert("Due Date Should Be Greater Than Start Date");
        }

    });

HTML

<input type='date' id="tsdate" class="form-control col-md-6 data-controller" placeholder="mm-dd-yyyy"
               name="startdate">  // class data-controller added
<input type='date' id="tedate" class="form-control col-md-6 data-controller" placeholder="Enter Due Date"
               name="enddate"
               required/> // class data-controller added
