Currently
$_POST["borrower_id"]
is always "editbtn" all the time. So query always returns zero entries.
Your problem is this
<button type="submit" class="btn btn-success btn-sm" id="editbtn">Edit</button>
and this should probably something like this
<button type="submit" class="btn btn-success btn-sm" id="editbtn" bookid='.$row['id'].'>Edit</button>
$row['id'] depends on whatever your id field is named.
Also you have to change
var borrower_id = $(this).attr("id");
to
var borrower_id = $(this).attr("bookid");
This should work.

How to fix 'If(isset($_POST['Id'])) error' while editing the form in a PHP based CRUD application?

The "if(isset($_POST["titleId"]) && !empty($_POST["titleId"])" in my code is returning false value.
I'm working on a CRUD application, the insert modal is working fine, now I'm stuck at the update part of it. So when you click on the update icon it does fetch the right titleId in the URL but the first 'if' condition returns false and hence the update isn't working.
Here's what I've tried so far.
admin.php
<?php
$typeId = filter_input(INPUT_GET, "type");
$titleId = filter_input(INPUT_GET, "titleId");
$active = "admin" . $typeId;
require_once './pages/header.php';
require_once './functions/queries.php';
$getAll = Queries::getAllTitle($typeId);

The only goal here is to get the update form working, the user should be able to update the records of the respective title being selected.
I don't know crud but I think there is a way to debug a little:
e.g. try this:
if(isset($_POST["titleId"]) && !empty($_POST["titleId"])){
// test if you are here:
echo 'hi, yeah I am here!';
}
or this
echo '<pre>';
var_dump($_POST);
echo '</pre>';
// before:
if(isset($_POST["titleId"]) && !empty($_POST["titleId"])){
// ...
}
also, take a look at
error_get_last()['message']

You are sending contactId and in your PHP you are looking for userid. Change your data to data: { userid: userid }.
$(document).on("click", ".edit-data", function() {
var userid = $(this).attr("id");
$.ajax({
url: "index.php",
method: "POST",
data: { userid: userid },
dataType: "json",
success: function(data) {
$("#name").val(data.name);
$("#email").val(data.email);
$("#description").val(data.description);
$("#contactUserId").val(data.userid);
$("#add").val("Update");
$("#myModal").modal("show");
}
});
});

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>

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);
