Saving table data to MySQL

Saving table data to MySQL

Saving table data to MySQL

I have just about finished my first ever PHP project (a Sports Club Management System converted from a Del[phi app) and I am left with one thing to complete. The attendance register. More specifically saving the data back to the MySQL table. Everything else works fine

Basically the attendance table has the following structure

The latter field is a string in the format "1,0,1,1,1,0,0,1,1,1,0,0,1" where each 0 or 1 signifies attendance at each of the 13 sessions available in the term.

Each session will have no more than 25 attendees.

The data is assembled into a table, within a form, with each table row consisting of 15 <td>s. The first is an indicator (used to show expanded member data), the second the members name, and the remainder the 13 attendance indicators as checkboxes (1= Attended, 0 = not attended)

The code used to build the table is:


                            while($g_fetch = $a_query->fetch_array()) {
                                $checked = array();
                                $memid = $g_fetch['mem_id'];
                                $name = $g_fetch['firstname'].' '.$g_fetch['lastname'];
                                $attendences = explode(",",$g_fetch['attend']);
                                for ($x = 0; $x <= 12; $x++) {if ($attendences[$x]!="0") {$checked[$x] = 'checked = "checked"';} else { $checked[$x] = '';}}
                                /* Now display table data rows */
                                echo '<tbody><tr class="parent">';  
                                echo '<td><i class="fa fa-chevron-down"></i></td>';
                                echo '<td name="'.$memid.'">'.$name.'</td>';
                                for ($y = 0; $y <= 12; $y++) { 
                                  if ($y <> $NoWeeks){ $dis = ' disabled'; } else {$dis = '';}
                                  echo '<td align="center"><input type="checkbox"  value = "1" '.$checked[$y].'" "'.$dis.'></td>';
                                echo '</tr>';
                                echo '<tr class="cchild">';
                                echo '<td colspan="5">';   
                                echo "Parent Name: <b>".$g_fetch['parent_name']."</b><br />";
                                echo "Parent Tel: <b>".$g_fetch['parent_tel']."</b><br />";
                                echo "Emergency 1: <b>".$g_fetch['emergency1']."</b><br />";
                                echo "Emergency 2: <b>".$g_fetch['emergency2']."</b><br />";
                                echo '</td>';
                                echo '<td colspan="5" >';   
                                echo '</td>';   
                                echo '<td colspan="5" >';
                                echo '</td>';   
                                echo '</tr></tbody>'; 

This works ok, but am having trouble saving the data back to the table after clicking on the form Save button (set up as a POST)
I have read that I need to set up the checkboxes as an array and assign a different value to each.
I assume this means for each checkbox setting it to something like name="attend[".$y."]"
Now I am stuck - I assume that for each row I can use the second <td>s name to find the record to update, and that I can assemble the attend[] elements to build the attendance string.
However I cannot seem to get the looping through the rows to get the various elements to work.
Any help gratefully received.
Many thanks
