You can do as follows:
Set unique id to your select and getdata.
<select id="select'+counter+'">
<td id="getdata'+counter+'"></td>
You can call change function of select separately or pass id to myfunc and parse it from there.
$(document).on('change', 'select[name="name[]"]', function(){
idName = $(this).attr('id'); //finding id of the element
id = idName.substring(6, idName.length); //finding id number
var datavalue = $(this).val();
myfunc(datavalue, id);
});
Change your myfunc as follows.
function myfunc(datavalue, id) {
$.ajax({
url:'getdata.php',
type:'post',
data:{
datapost:datavalue
},
success:function(result){
$('#getdata'+id).html(result);
}
});
}
And also you need to be careful on maintaining unique ids when deleting rows. You can check here how to dynamically add and remove rows.

How to edit design in a bootstrap template?

How do I edit the design hidden somewhere in this code? Currently this has a functioning search and I want to put an Add button next to a textbox. But I cannot even find the search in this code I'm showing below. I found this datatable template bootstrap on youtube.

I discovered that this code was triggering the whole design. Therefore, is there anyway I can show the 'hidden' code in this script? I just want to pud an add button and a textbox next to the search.
<script type="text/javascript">
$(document).ready(function() {
$('#example').DataTable();
});
</script>
Ok not sure I totally understand your requirements but going from your original post it says an add button by the search box that allows you to insert rows into the datatable. the solution below adds an inline form in the toolbar. then the onclick event adds the row to the datatable.
function category(id, name, action) {
var self = this;
this.id = id;
this.name = name;
this.action = action;
}
function model() {
var self = this;
this.categories = [];
}
var mymodel = new model();
$(document).ready(function() {
mymodel.categories.push(new category('1', 'Cat1', 'Post'));
mymodel.categories.push(new category('2', 'Cat2', 'Get'));
mymodel.categories.push(new category('3', 'Cat3', 'Put'));
var table = $('#mytable').DataTable({
data: mymodel.categories,
columns: [{
data: 'id'
}, {
data: 'name'
}, {
data: 'action'
}
],
dom: '<"toolbar">frtip'
});
$("div.toolbar").html(
'<form class="form-inline">\
<div class="form-group">\
<input type="text" class="form-control" id="rowid" placeholder="id">\
</div>\
<div class="form-group">\
<input type="text" class="form-control" id="name" placeholder="name">\

<input type="button" class="btn btn-danger" id="add" value="add"></input>\
</form>'
);
$('#add').click(function(event) {
table.row.add({
'id': $('#rowid').val(),
'name': $('#name').val(),
'action': $('#action').val()
}).draw(false);
})
});

Issue with foreach loop updating every record, rather than the ones just selected in a checkbox

I have a page with a dropdown box at the top populated from the database, when I select an item from the dropdown it gives a list of results with a checkbox at the end of each line, I want to be able to select, using each checkbox, any number of results, and submit a value back into a field in the database for each result selected.
I sort of have this working, but it submits the value to every field in the database, rather than just the ones selected

No worries. Just put the code of insert query inside foreach() loop. Like this:
foreach($_POST['check_list'] as $item)
{
$sql="INSERT/UPDATE Query";
//for example
$sql = "INSERT INTO table_demo (field_1, TARGET_FIELD, field_2, field_3) VALUES (val_1, $item, val_2, val_3)";
$insert = mysqli_query($connection,$sql);
}
//next code of your choice
That is really Easy to give a go.
See this is same as you want.
In this link the first answer by Sean Valsh is your solution.
Giving the array as name of every checkbox will give you only chacked option's id in array while submitted.

Session Variables in Datatables Plugin

I am creating a PHP/MySQL based application and it need to be able to carry over session variables into the DataTable plugin I use on a page in my app. The application is rather complicated, so I will explain how it works before I ask specific questions.
On index.php, there is a dropdown menu that shows the departments that use this application within my organization. The department list is generated by a mySQL table that has their department name and department code. The $dept variable stores the department code value from the selected option in the dropdown menu on submit. In turn, the $_SESSION["department"] variable stores $dept and redirects to the checkin page if successful.
<?php
require_once('connection.php');
session_start();
if (isset($_POST['submit']))
{
$dept = $_POST['dept'];
$_SESSION["department"] = $dept;
header("Location: checkin.php");
}
?>

The session variable is then carried throughout the site and is used to determine which table needs to be shown. For instance, in checkin.php, we need to display staff members in a dropdown list. We have multiple tables based on the departments using the application. One table we have is called ts_staff If the session variable is stored as the string ts, we do the following steps to make sure the app is connecting to the right database:
We store the session variable from index.php into a global variable on checkin.php $dept = $_SESSION[department];
We create another new variable to concatenate the global variable and the _staff string which is used in all our mySQL staff tables: $staffTable = $dept . "_staff";
Lastly, we use the $staffTable variable as the database table that needs to be displayed: $query = mysqli_query($VisitorManagement, "SELECT * FROM {$staffTable}");
Here's the full checkin.php code:
<?php
// connect to database
require_once('connection.php');
session_start();
//get session variable, if empty, unset and logout
if(empty($_SESSION['department'])) {
session_unset();
session_destroy();
header("Location: index.php");
} else {
$dept = $_SESSION[department];
}
//submit values on submit
if (isset($_POST['submit']))
{
// store form data values
$suid = mysqli_real_escape_string($VisitorManagement, $_POST['suid']);
$staff = mysqli_real_escape_string($VisitorManagement, $_POST['staff']);
$checkinTable = $dept . "_checkin";
// insert varaibles into table rows
$sql = "INSERT INTO {$checkinTable} (suid, staffMember) VALUES ('$suid', '$staff')";
// check if row was inserted correctly
if (mysqli_query($VisitorManagement, $sql)) {
header('Location: thank-you.php');
} else {
echo "Error: " . $sql . "<br>" . mysqli_error($VisitorManagement);
}
}
?>

The problem is that on reports.php, I am using the DataTables plugin to dynamically organize and filter a table, but I need to be able to carry the session variable over into the plugin so it knows to organize the specific table based on what the user selected on the index.php screen.
reports.php just calls DataTables and using another page, response.php to turn the data from the table into JSON to be displayed. Here's reports.php:
<?php session_start();
if(empty($_SESSION['department'])) {
session_unset();
session_destroy();
header("Location: index.php");
} else {
$dept = $_SESSION[department];
}
$checkinTable = $dept . "_checkin";
?>

"recordsFiltered" => intval($totalRecords),
"data" => $data // total data array
);
echo json_encode($json_data); // send data as json format
?>
In response.php, I need to able to replace ts_checkin, which is shown on this line:
$sql = "SELECT id, suid, staffMember, studentName, studentEmail, date_format(checkinDateTime, '%b %d, %Y, %h:%i %p') as checkinDateTime FROM `ts_checkin`";`
with a variable called $checkinTable that would concatenate similar to how checkin.php does with the staff table. So essentially I would like to have $checkinTable = $dept . "_checkin" with $dept equaling the value of the session variable.
When I go to do this, I get this error from DataTables: DataTables warning: table id=checkin - Invalid JSON response. For more information about this error, please see http://datatables.net/tn/1
Is it possible to get this working? I would like to keep DataTables as its the best way to achieve on-the-fly table filtering, searching, and sorting (plus it's a highly requested feature by our departments). But I need to be able to set the table based on the session variable.
I apologize for the length of this question. If there needs to be clarification, let me know.
I'm not certain to understand the question...
Are you saying this is not working ?
Did you try it written like this?
(notice the space after FROM. It is necessary!)
$checkinTable = $dept . "_checkin";
$sql = "SELECT id, suid, staffMember, studentName, studentEmail, date_format(checkinDateTime, '%b %d, %Y, %h:%i %p') as checkinDateTime FROM " . $checkinTable;
For sure, $dept has also to be defined.
And the resulting $checkinTable has to be an existing table name.
Ok...
This looks to be missing in your response.php:
session_start();
$dept = $_SESSION[department];
$checkinTable = $dept . "_checkin";

PHP Ajax Display Records From Drop Down List then Update Records are not working

My application asks the user to select the date from the drop down list. After selecting the date, it will display the list of students who took the exam on that date. The user will then can encode grades then save it. But the saving part is not working.
Here is the code.
$queryselect = mysql_query("SELECT examdateno, examdate from tbl_examdate ORDER BY examdate DESC");

jQuery Loading Content into a Div with CodeIgniter

I am trying to dynamically load content from my database into a div in my view called dynamic. I have a grid of products to the left of the dynamic div and when a user clicks on one of them I want the dynamic div to be populated with details on the product that they clicked on. Additionally, I would like the page to load with the first product selected and displayed automatically. I have tried to follow several tutorials on how to do this, but all I have done is run in circles. Any help is appreciated. My code is below:
Controller (category.php):
public function product() {
$product_id = $_POST['product_id'];
$data['product'] = $this->Category_model->getOneProduct($product_id);
}
Model (Category_model.php):
public function getOneProduct($id) {
$result = $this->db->query("SELECT *
FROM product
WHERE product_id = ?", array($id));
return $result->row_array();
}
View (category_view.php):

</code>
In product(), Make the product_id come from GET instead of POST so that your links will work without javascript.
$product_id = $_GET['product_id'];
In getOneProduct($id):
return json_encode($result->row_array());
HTML:
<table width="50%" cellpadding="5" id="product-grid">
<!-- snip -->
<a href="/your/url/product?product_id=<?php echo $product['product_id']; ?>" data-product-id="<?php echo $product['product_id']; ?>">
<img src="<?php echo base_url(); ?>products/<?php echo $product['product_thumbnail']; ?>" />
</a>
example javascript (jquery):
$('#product-grid a').click(function(e){
e.preventDefault();
$.ajax({
type: "GET",
url: "/your/url/product",
data: "product_id=" + $(this).attr('data-product-id'),
success: function(msg){
var product_data = jQuery.parseJSON(msg);
// do something with product_data
$('#dynamic').html('New product: ' + product_data.product_id);
}
});
});
