how to use mysql stored procedure with insert into table

Question

<?php

 $mysqli = new mysqli('localhost' 'root', "", 'scandi');

// check connection
if ($mysqli->connect_error) {
  trigger_error('Database connection failed: '.$mysqli->   connect_error , E_   USER_ERROR);
   }

$regid = mysqli_real_escape_string($mysqli, $_POST['regid']);
$startdate = mysqli_real_escape_string($mysqli, $_POST['startdate']);
$enddate = mysqli_real_escape_string($mysqli, $_POST['enddate']);

$query="DROP PROCEDURE IF EXISTS filldates ;

CREATE PROCEDURE filldates(dateStart DATE, dateEnd DATE)
BEGIN
 WHILE dateStart <= dateEnd
 DO
  INSERT INTO mydates (did,_date,regid) VALUES ('1',dateStart,'$regid');
 SET dateStart = date_add(dateStart, INTERVAL 7 DAY);
 END WHILE;
   END;
     CALL filldates('$startdate','$enddate')";

       if (mysqli_query($mysqli, $query)) {
    do {
     if ($result = mysqli_store_result($mysqli)) {
       mysqli_free_result ($result);
}
if (mysqli_more_results ($mysqli)) {

}
}while(mysqli_next_result ($mysqli));
}

  mysqli_close($mysqli)
?>

I want to store dates in the table (mydates), the $regid, $startdate, $enddate are provided by the user, the 'did' is auto_increament. the above code without mysqli works well in CLI and stores the dates in the table, but fails when i try to use it in php pages. Any one to help?

Instead of writing the procedure in the code, You can also store the procedure into the database and then call that procedure into your code like this

<?php 
  //connect to database
  $connection = mysqli_connect("hostname", "user", "password", "db", "port");

  //run the store proc
  $result = mysqli_query($connection, 
 "CALL ProcedureName()") or die("Query fail: " . mysqli_error());

  //loop the result set
  while ($row = mysqli_fetch_array($result)){   
  echo $row[0] . " - " . + $row[1]; 
  }
?>
