SQL SELECT Statement + Ajax not working - php

Well, this is a crud application which contains add/edit/delete options and I wanted to implement in order to add an other button to view a selected row but my query doesn't work, I am sending an http request with Ajax and am getting the data but the query doesn't work.

My query to view the data is :

echo $result = mysqli_query($this->conn, $sql) or die("error to view employee data");
}
Any idea , what should I do to select data from database and print them in html form ?

You are using the wrong variable name from $_REQUEST, you are using ìd when you should use view_id as it is configured in the form hidden field.
Try
function viewEmployee($params) {
$data = array();
//print_R($_POST);die;
$sql = "Select employee_name FROM employee WHERE id='".$params["view_id"]."'";
$result = mysqli_query($this->conn, $sql) or die("error to view employee data");
echo json_encode($result->fetch_all(MYSQLI_ASSOC));
}

</form>
here my ajax script :
$(document).on("keypress", ".idkurir", function(e) {
var idkurir = $('#idkurir').val();
if (e.which == 13) {
$.ajax({
type: "POST",
url: "checkdata.php",
data: {
idkurir: idkurir
},
success: function(response) {
if (response == 1) {
alert("Kurir sudah laporan");
} else {
if (response == "ID Kurir tidak di temukan") {
alert(response);
} else {
var d = new Date();
var today_date = ("0" + d.getDate()).slice(-2) + ("0" + (d.getMonth() + 1)).slice(-2);
$('#nolaporan').val(idkurir + today_date);
$('#namakurir').val(response);
}
}
}
});
}
});
and here my checkdata to check if data exist :
session_start();
$connect = mysql_connect("localhost", "root", "");
mysql_select_db("reportchecker", $connect);
$idkurir = $_POST["idkurir"];
$nolaporan = $idkurir . date("dm");
$sql = "SELECT * FROM jampulang WHERE nolaporan = '$nolaporan'";
$result = mysql_query($sql, $connect);
$count = mysql_num_rows($result);
$response = [];
$sql2 = "SELECT * FROM kurir WHERE idkurir = '$idkurir'";
$result2 = mysql_query($sql2, $connect) or die(mysql_error());
$count2 = mysql_num_rows($result2);
if ($count == 1) {
echo "1";
} else if ($count2 == 1) {
$row = mysql_fetch_array($result2) or die(mysql_error());
echo $row['nama'];
} else {
echo "ID Kurir tidak di temukan";
}
my problem is when response from checkdata = "ID Kurir tidak di temukan", ajax not showing alert and stop update field nolaporan and nama kurir
$('#nolaporan').val(idkurir + today_date);
$('#namakurir').val(response);
in my script above when reponse "ID Kurir tidak di temukan" still update field nolaporan and namakurir.
You can fix it on the client side using $.trim() like below:
if($.trim(response) == 'ID Kurir tidak di temukan') {
//do your code
}

PHP Ajax Update MySQL Data Through Bootstrap Modal

I want to update my database using php ajax modal. When updating the relevant field { $('#main_id').val(data.id); } don't pass an id to the update query therefor an insertion occurs without executing the updating query.
console log details when trying to update
I tried to solve this but I couldn't. without updating the existing data it inserts a new record
here is my index.php
<?php
$connect = mysqli_connect("localhost", "root", "", "ohmsp");
$query = "SELECT * FROM tbl_main_category ORDER BY cat_Id DESC";
$result = mysqli_query($connect, $query);
?>
<div id="employee_table">
<table class="table table-bordered">
<tr> <th width="70%">Employee id</th>
<th width="70%">Employee Name</th>
<th width="15%">Edit</th>
<th width="15%">View</th>
</tr>
<?php
while($row = mysqli_fetch_array($result))
{
?>
<tr> <td><?php echo $row["cat_Id"]; ?></td>
<td><?php echo $row["category_name"]; ?></td>
<td><input type="button" name="edit" value="Edit" id="<?php echo $row["cat_Id"]; ?>" class="btn btn-info btn-xs edit_data" /></td>
<td><input type="button" name="view" value="view" id="<?php echo $row["cat_Id"]; ?>" class="btn btn-info btn-xs view_data" /></td>

Live check availability inside dynamic form

I have 2 forms, static and dynamic form. Dynamic is optional, depends on user if they want to submit more than one inputs. The insertion process works fine. Then, I have a function to check the availability for the input that user want to insert. The thing is, the live check availability only works in static form. How I want to call back the live check availability function inside the dynamic form? Your help is truly appreciate :)

How to pass value from table to bootstrap modal to PHP?

I've fetched rows from MySQL and looped it with Bootstrap modal and I've made a form in modal from which the data is being sent to PHP script (update.php) with the help of ajax. But in return I am getting the output of last row only.
I need to get the record of specific student with its unique ID.

<?php
$query = "SELECT * FROM students ORDER BY id DESC";

This is not tested/debugged but refactor your code similar to this:

if($query_run){
$out = '

';
while($row = mysqli_fetch_assoc($query_run)){
$out .= '<tr class="trID_' .$row['id']. '">';
$out .= '<td class="td_name">' . $row['name'] . '</td>';
$out .= '<td class="td_rollno">' . $row['rollno'] . '</td>';
$out .= '<td class="td_contact">' . $row['contact'] . '</td>';
$out .= '<td class="td_address">' . $row['address'] . '</td>';
$out .= "<td><button class='td_btn btn btn-link btn-custom dis'>EDIT</button> </td>";
$out .= '</tr>';
}
$out .= '</tbody></table>
echo $out;
?>

Notes:
(1) Create the entire table in a variable, then output the variable all at once.
(2) You only need one modal, not one modal for each table row. Therefore, remove modal creation from inside while loop.
(3) Use jQuery to:
(a) detect button click in row
(b) get table data for that row
(c) populate fields in modal
(d) display modal
You are using Bootstrap, which uses jQuery, so it makes sense to use jQuery to do this.
(4) Using jQuery to get values from table cells vs. input fields:
(a) .text() - from table cells
(b) .val() - from <input> or <textarea>
Here is a jsFiddle Demo you can play with that demonstrates how you can use jQuery to populate the modal depending on the row that was clicked.

So, now I'd like to put a checkbox in each item for being able to select several records and delete them at once. Another question, when I edit a record if I put a text the field it's filled, but if I put a select it doesn't work. The idea is the select field has all options of countries and letting that item from the record already selected. I hope you understand what I need. Thanks.
From what I understand, you have two questions:
How to put checkboxes on your CRUD list in order to delete all items at once.
It seems that you are using update_list() to load all items on your table. Since thats the case, you need to add an extra <td> in that row to that iteration with the checkbox element.
data.results.forEach(function (i) {
$("#list").find("tbody").append(
"<tr>" +
"<td><input class='item_checkbox' type='checkbox'/></td>" +
"<td>" + i.pais + "</td>" +
"<td>" + i.nome + "</td>" +
"<td>" + i.empresa + "</td>" +
"<td align='center'><a class='btn btn-primary glyphicon glyphicon-pencil' title='Editar' id='edit_link' href='" + JSON.stringify(i) + "'></a> | <a class='btn btn-danger glyphicon glyphicon-trash' title='Deletar' id='delete_link' href='" + JSON.stringify(i) + "'></a></td>" +
"</tr>"
);
});
Once you have that set, you can then use jquery to collect all checkboxes by class .item_checkbox and run a delete function.
How to make sure the SELECT country field is pre-selected when you EDIT an item
Since you are using bootstrap modals, when you edit an item, that modal will popup showing that info. What you need to do is send that item's country ID to that modal's form so that it can be preselected, so do the following change:
first in #editar_modal
<div class="form-group">
<label class="control-label">País:</label>
<select id="pais_input" name="pais">
<?php foreach ($array_pais as $pais) { ?>
<option value="<?php echo $pais ?>"><?php echo $pais ?></option>
<?php } ?>
</div>
then in '#edit_link', 'click', function (e) add:
$modal.find("#pais_input").val(info.pais);
