Checkboxes inside a table with php foreach - php

Question

I have a pretty much simple issue with a table i create with PHP foreach (in codeigniter).
One column inside the table has 2 checkboxes. One true and one false so when i create the table has some names and infos and then 2 checkboxes. Whenever the user clicks the true I create an AJAX POST call to my database to change the state of a column. But when the user has clicked true and then he clicks false I want the true checkbox to be unchecked.
Here is the code
<table class="responstable">
<tr>
<th>ID</th>
<th><span>Name</span></th>
<th>number1</th>
<th>number2</th>
</tr>
<?php
foreach($students as $column => $data ) { ?>
<tr>
<td><?php echo $data[0]->Userproperties_UserAM; ?></td>
<td><?php echo $data[0]->Userproperties_UserFullName; ?></td>
<td><?php echo $data[0]->UserAbsence; ?></td>
<td> <input class="true" id="<?php echo $data[0]->Userproperties_UserId; ?>" type='checkbox' value="<?php echo $data[0]->Userproperties_UserAM; ?>" />
<label for='true'>
<span></span>
True
</label>
<input class="false" id="<?php echo $data[0]->Userproperties_UserId; ?>" type='checkbox' value="<?php echo $data[0]->Userproperties_UserAM; ?>" />
<label for='false'>
<span></span>
False
</label></td>
</tr>
<?php } ?>
</table>
And the ajax code
$(document).ready(function() {
$('.true').change(function() {
if($(this).is(":checked")) {
$('.false').attr('checked', false);
var moduleid = <?php echo $moduleid; ?>;
var teacherid = <?php echo $teacherid; ?>;
var studentid = $(this).attr('id');
var weeknum = $("#dropi").val();
jQuery.ajax({
type: "POST",
url: "<?php echo base_url(); ?>" + "index.php/TeacherParousies/send_parousia",
data: {
moduleid: moduleid,
studentid: studentid,
teacherid: teacherid,
parousia: 1,
weeknum: weeknum
},
success: function(res) {
},
error: function(err) {
}
});
}
});
$('.false').change(function() {
if($(this).is(":checked")) {
$('.true').attr('checked', false);
var moduleid = <?php echo $moduleid; ?>;
var teacherid = <?php echo $teacherid; ?>;
var studentid = $(this).attr('id');
var weeknum = $("#dropi").val();
jQuery.ajax({
type: "POST",
url: "<?php echo base_url(); ?>" + "index.php/TeacherParousies/send_parousia",
data: {
moduleid: moduleid,
studentid: studentid,
teacherid: teacherid,
parousia: 0,
weeknum: weeknum
},
success: function(res) {
},
error: function(err) {
}
});
}
});
});
The problem here is that when i check the 2nd row of the table's checkbox lets say false, there is a change on the 1st row for true if it is checked.
Although I have stated
if($(this).is(":checked"))
Any idea?

In your case it .false and .true will uncheck all. You just need to check the nearest element.
Kindly replace the code $('.true').attr('checked', false); with this code $(this).closest( "td" ).find('.true').attr('checked', false);
and do same with for $('.false').attr('checked', false); this $(this).closest( "td" ).find('.false').attr('checked', false);
