How do update a specific row using checkboxes - php

Question

I'm trying to update specific rows in a table that is built from a form. I am using checkboxes but the whole table is being updated instead of the specific row that I am filling in. I tried ISSET to see if I could get it to only update when the boxes were ticked, but that didn't work. Here's what I have (obviously not the whole code, but I can provide more as needed):
<?php
include 'connect.php';
// All possible parameters
$params = array(
'Student',
'homeroom',
'teacher'
);
$wheres = array();
foreach ($params as $param) {
// Is the param set?
// If so, let's add it to our list of WHERE clauses
if (isset($_GET[$param]) && !empty($_GET[$param])) {
$wheres[] = sprintf("%s LIKE '%%%s%%'", $param, mysqli_real_escape_string($connect, $_GET[$param]));
}
}
if ($db_found) {
// Now let's make the SQL.
$SQL = 'SELECT * FROM studentlist';
// We only want to add the WHERE clause if we had some parameters passed
if (count($wheres) > 0) {
$SQL .= ' WHERE ' . implode(' OR ', $wheres);
}
$result = mysqli_query($connect, $SQL);
while ($row = mysqli_fetch_array($result, MYSQLI_BOTH)) {
echo "<tr>";
echo "<td>" . $row['Student'] . "</td>";
echo "<td>" . $row['homeroom'] . "</td>";
echo "<td>" . "<input type='checkbox' name='responsibility' value='E'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='responsibility' value='G'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='responsibility' value='S'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='responsibility' value='N'>" . "</td>";
echo "<td>" . "" . "</td>";
echo "<td>" . "<input type='checkbox' name='organization' value='E'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='organization' value='G'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='organization' value='S'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='organization' value='N'>" . "</td>";
echo "<td>" . "" . "</td>";
echo "<td>" . "<input type='checkbox' name='independentwork' value='E'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='independentwork' value='G'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='independentwork' value='S'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='independentwork' value='N'>" . "</td>";
echo "<td>" . "" . "</td>";
echo "<td>" . "<input type='checkbox' name='collaboration' value='E'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='collaboration' value='G'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='collaboration' value='S'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='collaboration' value='N'>" . "</td>";
echo "<td>" . "" . "</td>";
echo "<td>" . "<input type='checkbox' name='initiative' value='E'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='initiative' value='G'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='initiative' value='S'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='initiative' value='N'>" . "</td>";
echo "<td>" . "" . "</td>";
echo "<td>" . "<input type='checkbox' name='selfregulation' value='E'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='selfregulation' value='G'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='selfregulation' value='S'>" . "</td>";
echo "<td>" . "<input type='checkbox' name='selfregulation' value='N'>" . "</td>";
echo "</tr>";
And then I have this as my update:
<?php
include 'connect.php';
// Get values from form
$resp=$_POST['responsibility'];
$org=$_POST['organization'];
$ind=$_POST['independentwork'];
$coll=$_POST['collaboration'];
$init=$_POST['initiative'];
$self=$_POST['selfregulation'];
// Insert data into mysqli
$sql = "UPDATE studentlist
SET responsibility='$resp', organization='$org', independentwork='$ind',
collaboration='$coll', initiative='$init', selfregulation='$self'";
$result=mysqli_query($connect, $sql);
// if successfully insert data into database, displays message "Successful".
if($result){
echo "Successful";
}
else {
echo "ERROR";
}
?>
<?php
// close connection
mysqli_close($connect);
?>
I understand that I have all the checkboxes named the same thing, but I'm not sure how to move away from that. And yes, I am new to this!!!!!

You have to add to the end of your querya WHERE condition to upsate just the row you want, if you use for example StudentId as the identifier of your Student then you write :
$sql = "UPDATE studentlistSET responsibility='$resp', organization='$org', independentwork='$ind',collaboration='$coll', initiative='$init', selfregulation='$self' WHERE StudentId='$studentId' ;
