How to add multiple checkboxes data to MySQL database using PHP PDO? - php

Question

try {
$qry = $conn->prepare("SELECT * FROM school_periods WHERE account_id = :a_id");
$qry->execute(array(':a_id'=>$_SESSION['user_account']));
$qry->setFetchMode(PDO::FETCH_OBJ);
while($row = $qry->fetch()) {
?>
<tr>
<td width='35%'><input type='checkbox' name='periods' value=''></td>
<td width='35%'><?=$row->period_name; ?></td>
<td width='35%'><?=$row->start; ?> </td>
<td><?=$row->end; ?></td>
</tr>
<?php
}
} catch(PDOException $e) {
echo 'ERROR: ' . $e->getMessage();
}
If the user checks the number of the checkbox, I want to add the checkbox name and value in the database. I tried to achieve this as follows:
<?php
$schoolyear = $_REQUEST['schoolyear'];
$start = $_REQUEST['start'];
$end = $_REQUEST['end'];
$start = date2mysql($start);
$end = date2mysql($end);
$holiday = $_POST['holiday'];
$status = 1;
$test = 0;
if ($test == 1) {
echo $schoolyear;
echo '<br />';
echo $start;
echo '<br />';
echo $end;
echo '<br />';
echo $status;
echo '<br />';
echo $_SESSION['user_account'];
}
try {
$sqladdyr = "INSERT INTO school_years (account_id,year_name,start,end,status,added,updated) VALUES (:a_id,:name,:start,:end,:status,NOW(),NOW())";
$q = $conn->prepare($sqladdyr);
$q->bindParam(":start", $start, PDO::PARAM_STR);
$q->bindParam(":end", $end, PDO::PARAM_STR);
$q->bindParam(":a_id", $_SESSION['user_account'], PDO::PARAM_STR);
$q->bindParam(":name", $schoolyear, PDO::PARAM_STR);
$q->bindParam(":status", $status, PDO::PARAM_STR);
$q->execute();
$id = $conn->prepare("SELECT MAX('year_id') FROM school_years");
//Set needed id.
$id->execute();
$id->setFetchMode(PDO::FETCH_OBJ);
while ($idval = $id->fetch()) {
$id_val = $idval->year_id;
}
foreach ( $holiday as $key => $value ):
$stmt = $conn->prepare("INSERT INTO holidays(account_id,year_id,holiday_name,start) VALUES(:a_id,:yid,:name,:date)");
$stmt->execute(array(
':a_id' => $_SESSION['user_account'],
'year_id'=>$id_val,
':name'=>$_POST['holiday'][$key],
':date'=>$_POST['holiday'][$value] // assuming this is the same for all rows?
));
endforeach;
} catch(PDOException $e) {
echo 'Error: ' . $e->getMessage();
}
Unfortunately, this does not seem to work. How can I solve this issue?
