Update & delete MySQL from modal bootstrap - php

Question

I´m trying to delete and/or update data from form inside a modal window .For create it I haven´t problem but with the others actions (delete and update) I always have a problem,I think the key is the "id" it seems take the last value and not the value that I want to delete or update.
I know my code could be more nice.
<div class="container">
<div class="row espacio">
<p class="col-md-1"><a data-toggle="modal" href="#myModal" class="btn btn-default glyphicon glyphicon-plus"><span></span></a></p>
<p class="col-md-1 col-md-offset-10"><span class="btn btn-default glyphicon glyphicon-envelope"></span></p>
<table class="table table-bordered">
<caption>Bitácora</caption>

<th>Tecnico</th>
<th>Turno</th>
<th>Información</th>
<th>Estado</th>
<th>Creada</th>
<th>Modificada</th>

$turno = $_POST["turno"];
$informacion = $_POST["informacion"];
$sql = "INSERT INTO bitacora (Name,Turno,Info,Estado,RecordDate,ModiDate) VALUES ('" . $nombre . "', '" . $turno . "', '" . $informacion . "','Pendiente',now(),now())";
$db->consulta($sql);
}
//formulario UPDATE
if(isset($_POST["actualizar"])) {

//form DELETE
if(isset($_POST["eliminar"])) {

$db->consulta($sql);
}here

Answer 1

It seems that your input named "id" is not taking the correct value of $row['Id']. Try to inspect it and see if his "value" is not empty.
If the value was empty, your problem is the value of $row['Id'].
Try to replace $row['Id'] by $row['id'] and see the results.
