This query is a part of the main query where Date search is applied along with other columns search. Here is the full query
SELECT * FROM table_name WHERE name LIKE '%John%' AND DATE BETWEEN '2017-03-02' AND '2017-03-11'
So we can replace WHERE with AND based on our requirement.
Using backend PHP Script
Usually the query is used in backend PHP script to handle records in a database. For this our form should submit data to backend script and query to be generated based on these data.
$dt1=$_POST['dt1'];
$dt2=$_POST['dt2'];
if(strlen($dt1) >5){ // if from date is filled
$date = new DateTime($dt1);
$dt1=$date->format('Y-m-d'); // To match MySQL date format
$sql= " AND dt >='$dt1' " ;
}
if(strlen($dt2) >5){ // if to date is filled
$date = new DateTime($dt2);
$dt2=$date->format('Y-m-d'); // To match MySQL date format
$sql= " AND dt <= '$dt2' " ;
}
if(strlen($dt1) >5 and strlen($dt2>5)){ // if both dates are filled
$sql= " AND dt between '$dt1' AND '$dt2' " ;
}
$sql=preg_replace("/AND/","WHERE",$sql,1); // Remove first AND with WHERE
Now above code can be joined with our main Query like this.
