by means of an if attempt that can not be created two records with the same name, it does not work and you can create a record with a dupiclate name
this is the controller
include_once 'model/solucion.php';
public function Guardar()
{
$this->model->Duplicado($_POST['Nombre']);
$name = $this->model->resultado2['Nombre'];
if($name == $_POST['Nombre']){
die("No se puede crear una solucion con el mismo nombre");
}else{
$solucion = new solucion();
$solucion->id = $_REQUEST['id'];
$solucion->Nombre = $_REQUEST['Nombre'];
$solucion->Tipo = $_REQUEST['Tipo'];
$solucion->Descripcion = $_REQUEST['Descripcion'];
$solucion->Pagina = $_FILES['Pagina']['name'];
}
header("Location: index.php");
}
this is the model
public $resultado2;
public function Duplicado($Nombre)
{
try {
$stm = $this->pdo->prepare("SELECT * FROM fallas WHERE Nombre = '$Nombre'");
$stm->execute();
$res=$stm->fetch(PDO::FETCH_ASSOC);
$this->resultado2 = array();
$i = 0;
foreach ($res as $row)
{
$this->resultado2[$i]['id'] = $row['id'];
$this->resultado2[$i]['Nombre'] = $row['Nombre'];
$this->resultado2[$i]['Tipo'] = $row['Tipo'];
$this->resultado2[$i]['Descripcion'] = $row['Descripcion'];
$this->resultado2[$i]['Pagina'] = $row['Pagina'];
$i++;
}
} catch (Exception $ex) {
die($e->getMessage());
}
}
this is the view

What do I have to change in the controller to avoid creating duplicate records with the same name?
You need to pass the array and check whether this is empty or not . Check below for the code and run it and let me know if you get any error .
public function Duplicado($Nombre)
{
try{
$stm = $this->pdo->prepare("SELECT * FROM fallas WHERE Nombre = '$Nombre'");
$stm->execute();
$res=$stm->fetch(PDO::FETCH_ASSOC);
return $res;
}catch (Exception $ex) {
die($e->getMessage());
}
}
include_once 'model/solucion.php';
public function Guardar()
{
$name = $this->model->Duplicado($_POST['Nombre']);
//$name = $this->model->resultado2['Nombre'];
if(!empty($name)){
die("No se puede crear una solucion con el mismo nombre");
}else{
$solucion = new solucion();
$solucion->id = $_REQUEST['id'];
$solucion->Nombre = $_REQUEST['Nombre'];
$solucion->Tipo = $_REQUEST['Tipo'];
$solucion->Descripcion = $_REQUEST['Descripcion'];
$solucion->Pagina = $_FILES['Pagina']['name'];
}

Need some help doing my update Ajax call. What I want my code to do is to show when on click my update form and pass the data from the form to my update via AJAX. So far the form isn't showing on click nor is the update working. Everything else seems to be working right except for that.

You are POSTing to the page but checking for GET.
Good manual pages to read:
Handling external variables
Example:
$.post("app/update.php",
{
id: id
alert(id);
},
That will send a POST to the app/update.php script you have which contains the following:
<?php
// $GET is not the same as $_GET
if(isset($GET['id'])){
require '../includes/conn.php';
include 'func.php';
$id = $GET['id'];
echo $id;
This will not work given that you are POSTing but looking incorrectly at $GET (which should be $_GET).
To fix change the following lines to:
<?php
if($_POST['id']){
require '../includes/conn.php';
include 'func.php';
$id = $_POST['id'];
echo $id;
Please note that $GET and $_GET aren't the same things, nor are $POST and $_POST.
I've been fiddling with this for hours and cant figure out why the $_GET statements perform correctly, but the $_POST statements don't.
IF $stock is in dB, show values in the form, and if the form is submitted submit UPDATE those values, IF $stock is NOT in dB and the form is submitted INSERT into table. Neither $_POST statement seems to work, yet are not throwing any errors, just redirecting back to the same page when you hit the submit button.

Replace
if(isset($_POST['Submit']))
with
if (!empty($_POST))
this checks in general if anything has been posted (if the POST request is not empty -> do this)
Please verify your submit have this ...
<input type="submit" value="Submit" name="submit" />
and your form method is
<form method="POST" action="xyz"> ...
Your code is a bit off.
You're checking
if(isset($_POST['Submit'])) {
Which is not being posted at all. This is why, the if part never gets executed.
You can try to check if it is POST request by
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
// …
}
maybe this helps.
You should use filter_input to handle POST and GET params. Using $_POST or $_GET is deprecated.
I've been testing a CRUD interface with PHP and SQLSRV driver but i got stuck on the creating part, i can read the data that alredy was added on the database by id, but i cant get to work the create data from PHP to the database, when i press the create Button it clears the inputs and shows the errors. Would like to know if there is something wrong with my code so far.
PHP CODE:
<?php
require 'database.php';
if ( !empty($_POST)) {
$iError = null;
$nError = null;
$dError = null;
$tError = null;
$id = $_POST['id'];
$name = $_POST['name'];
$Address = $_POST['Address'];
$phone = $_POST['phone'];
$valid = true;
if (empty($id)) {
$iError = 'add id';
$valid = false;
}
if (empty($name)) {
$nError = 'add name';
$valid = false;
}
if (empty($Address)) {
$dError = 'add address';
$valid = false;
}
if (empty($phone)) {
$tError = 'add phone';
$valid = false;
}
if ($valid) {
$tsql = "INSERT INTO dbo.TEST1 (id, name, Address, phone) values(?, ?, ?, ?)";
$arr1 = array($id, $name, $Address, $phone);
$stmt = sqlsrv_query($conn, $tsql, $arr1 );
if ( $stmt === FALSE ){
echo "New data created";
}
else {
echo "Error creating data";
die(print_r(sqlsrv_errors(),true));
}
}
}?>`

I'm attempting to add the update function to my CRUD application. Essentially it uses the database specified, and uses the 'id' from the index.php page, which is 'productID' from the database. In another part of the application, a store management feature is included with the same skeleton Update page and works perfectly.
The database (Product) contains productID(PK), productName, productPrice, storeID(FK), productDate, productComments, productQuantity, and productPortion.
I'm certain it's within the PHP script, likely around the UPDATE command after using a few error checks but I can't seem to figure out what might be the main issue.

Having a quick look at your code you are sending the form data via $_POST and on the php script checking $_GET then grabbing the id from $_REQUEST. Try changing
if ( !empty($_GET['id'])) {
$id = $_REQUEST['id'];
}
to
if ( !empty($_POST['id'])) {
$id = $_POST['id'];
}
Hope that helps!
Thanks Donniep!
I found that the answer was actually related to the POST values after being submitted. My impression was that I could still use the value from the GET call of 'id', but I instead needed to use the actual ID value from the product DB instead. The solution turned out to be:
// keep track post values
$id = $_POST['id'];
Needed to be changed to:
// keep track post values
$id = $_POST['productID'];
