How to fill input fields in form with data from row in html table I want to edit

Question

I have this HTML table with data from MySQL database and form for adding/editing rows in this table. If I add new row, everything works fine, but when I want to edit, I dont know how to pre-fill input text fields in this form. I have id of specific row saved as id of each editing button, but I dont know how to get know the ID from this clicked button. And should I have to do it with PHP or JS?

<table class="table table-striped">
                    <thead>
                    <tr>
                        <th> Poradi</th>
                        <th> Jmeno</th>
                        <th> Prijmeni</th>
                        <th> Adresa</th>
                        <th> Mesto</th>
                        <th> Telefon</th>
                        <th> Email</th>
                    </tr>
                    </thead>
                    <tbody>
                    <?php
                    $db = new PDO(
                        "mysql:host=localhost;dbname=xyz",
                        "xyz",
                        "xy"
                    );

                    $stmp = $db->prepare("SELECT * FROM user");
                    $stmp->execute();
                    $data = array();
                    while ($row = $stmp->fetch()) {
                        $data[]=($row);
                        echo "<tr>
                                <td>" . $row['id'] . "</td>
                                <td>" . $row['login'] . "</td>
                                <td>" . $row['password'] . "</td>
                                <td>" . $row['name'] . "</td>
                                <td>" . $row['surname'] . "</td>
                                <td>" . $row['address'] . "</td>
                                <td>" . $row['city'] . "</td>

                    }

                    ?>

I was on the same page when I have started.

You should use

echo "<a href=\"edit.php?id=".$row['id']."\"><i class='glyphicon glyphicon-pencil' id=$id></i></a>

On edit.php you will use $_GET['id'] to get the id of clicked element.

Your solution would be helpful, but I dont want to redirect or refresh website, I wanted to do that just dynamically. I've found different solution which works but anyway, thanks a lot for inspiration :)

You need to tell you script whichrecord you want to edit.

Best way will be to add href to your edit anchor.

echo "<a href="/url/to/this/script?id=$id"><i class='glyphicon glyphicon-pencil' id=$id></i></a></td>

Now after refresh you can get id of record you want to edit by:

// this way provide some base security
$id = filter_input(INPUT_GET, 'id', FILTER_SANITIZE_NUMBER_INT);

// Now get record from database (only sample call - need to build prepare statement)
$record = $database->getRecordById($id);

// After that fill form with record data
<input type="text" name="name" placeholder="Jmeno" value="<?php $record->name ?>" required autofocus>

I found a solution I was looking for. Advices from guys here are right as well in case it never mind you redirect from your site.

I wanted to do it dynamically with jQuery if it would be possible and I've found this solution which works for me perfect, so I share it here.

jQuery: Get the contents of a table row with a button click
