Search by date range and by keyword - php

Question

For report generation in the project I made I want to use 2 methods:
By date range (from date and up to date)
By employee ID
While using the above keywords the complete record of the employee should be displayed in that particular range.
For ex- emp1234 is the employee whose record is to be checked between date 20 may 2018 to 30 june 2018. The result must be displayed in between the range
Another thing is that the search can be done either by date or by employee id or both but both should not be compulsory.
the script is as follows:
<script>
$(document).ready(function(){
$.datepicker.setDefaults({
dateFormat: 'yy-mm-dd'
});
$(function(){
$("#from_date").datepicker();
$("#to_date").datepicker();
});
$('#filter').click(function(){
var from_date = $('#from_date').val();
var to_date = $('#to_date').val();
if(from_date != '' && to_date != '')
{
$.ajax({
url:"filter.php",
method:"POST",
data:{from_date:from_date, to_date:to_date},
success:function(data)
{
$('#report_table').html(data);
}
});
}
else
{
alert("Please Select Date");
}
});
});
</script>
<script>
$(document).ready(function(){
load_data();
function load_data(query)
{
$.ajax({
url:"fetch.php",
method:"POST",
data:{query:query},
success:function(data)
{
$('#report_table').html(data);
}
});
}
$('#search_text').keyup(function(){
var search = $(this).val();
if(search != '')
{
load_data(search);
}
else
{
load_data();
}
});
});
</script>
I need to combine these two different queries into one.

I want these to separate fetch and filter files into one file.
Please help.

Answer 1

please dont delete the question again, i was writing a few minutes and then the question was deleted haha
soo, as you have a filter button which has to be clicked to get the results there are two ways you can choose!
you display your table with datatable plugin which means you only need to filter by date and then write the employeeid in the searchbox and you will only see the results for this person WITHOUT having to query it again!
https://datatables.net/
you get the two dates AND your search query by clicking on the filter button which means you will only have one php file (i dont know why you actually want to use fetch & filter).. In your php file you then look if there are only dates submitted OR the query is also submitted:
$('#filter').click(function(){
var from_date = $('#from_date').val();
var to_date = $('#to_date').val();
var query = $("#search_text").val();
if(from_date != '' && to_date != '')
{
$.ajax({
url:"filter.php",
method:"POST",
data:{from_date:from_date, to_date:to_date, employee: query},
success:function(data)
{
$('#report_table').html(data);
}
});
}
else
{
alert("Please Select Date");
}
});
in php file
if(isset($_POST["employee"]) AND $_POST["employee"] != "") {
// make your sql call with dates AND employeeid
} else {
// make your sql call only with dates
}
depending on how many results you have I'm sure its also possible to dont even have to query again for different dates and instead tweak datatable so that you have one from_date, one to_date and one search field and filter the table after keyup.. see example here: https://datatables.net/examples/api/multi_filter.html
