I am trying to update the records but the update query is not working for some reason.It is deleting and inserting fine but somehow the update doesn't work.I have checked various questions but couldn't find the answer.I have checked the data inserted in the query and its fine too.This is my code.
<?php
require 'database.php';
$ido = 0;
if ( !empty($_GET['id'])) {
$ido = $_REQUEST['id'];
echo $ido;
}
if ( !empty($_POST)) {
// keep track validation errors
$nameError = null;
$descError = null;
$priceError = null;
// keep track post values
$name = $_POST['name'];
$desc = $_POST['desc'];
$price = $_POST['price'];
// validate input
$valid = true;
if (empty($name)) {
$nameError = 'Please enter Name';
$valid = false;
}
if (empty($desc)) {
$descError = 'Please enter Valid descriptin';
$valid = false;
}
if (empty($price) || filter_var($price, FILTER_VALIDATE_INT) == false) {
$priceError = 'Please enter a valid price';
$valid = false;
}
// insert data
if ($valid) {
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "UPDATE Items SET I_name = ? , I_desc = ? ,I_price = ? WHERE I_id = ?"; <---This is the update query part
$q = $pdo->prepare($sql);
$q->execute(array($name,$desc,$price,$ido)); <---these are the values inserted
Database::disconnect();
header("Location: index.php");
}
}
else {
echo $ido;
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "SELECT * FROM Items where I_id = ?";
$q = $pdo->prepare($sql);
$q->execute(array($ido));
$data = $q->fetch(PDO::FETCH_ASSOC);
$name = $data['I_name'];
$desc = $data['I_desc'];
$price = $data['I_price'];
Database::disconnect();

This is your form:
<form class="form-horizontal" action="update_items.php" method="post">
^ nothing here
As you can see you are posting and there is no query variable after the url you are posting to.
Then you check for the ID:
$ido = 0;
if (!empty($_GET['id'])) {
$ido = $_REQUEST['id'];
echo $ido;
}
$ido will remain 0 as there is no $_GET['id'].
You can either modify your form to add the ID or add a hidden variable in the form with the ID and check for $_POST['id'].
I'd go for the second option:
<form class="form-horizontal" action="update_items.php" method="post">
<input type="hidden" name="id" value="<?php echo $ido; ?>">
and in php:
if (!empty($_POST)) {
$ido = $_POST['id'];

I have a table in my php where I show data from my 'users' table of mysql. In the table I added an edit button so that, if you click on the button, a form is shown below the table where you can edit some fields of the table's content, I have also added a delete button next to it to delete the row of the table you want, but that button works correctly.
The problem I have is with the edit button, which, when pressed, it doesn’t show me the form that I added below the table, but it takes me to the page 'registerTeacher.php?edit = 3' for example. Pressing the 'Edit' button, it should show the form to be able to edit but it doesn’t do anything, nor does it show me any errors. Can someone help me find where the problem is? Thank you.
This is my ‘indexAdmin.php’ code:
<?php
include('server.php');
include('Security.php');
include('Conexion.php');
include('registerTeacher.php');
?>
<?php
$style = "style='display:none;'";
if (isset($_GET['edit'])) {
$id = $_GET['edit'];
$update = true;
$record = mysqli_query($conn, "SELECT * FROM users WHERE id=$id");
if (#count($record) == 1 ) {
$n = mysqli_fetch_array($record);
$username = $n['username'];
$email = $n['email'];
$style = "style='display:block;'";
}
}

This is my ‘registerTeacher.php’ file:
<?php
include('Conexion.php');
$username = "";
$email = "";
$errors = array();
$id = 0;
$update = false;
// UPDATE
if (isset($_POST['update'])) {
$id = $_POST['id'];
$username = $_POST['username'];
$email = $_POST['email'];
mysqli_query($conn, "UPDATE users SET username='$username', email='$email' WHERE id=$id");
$_SESSION['message'] = "User edited!";
header("Location: indexAdmin.php?page=professors");
}
?>
Because <a href=..> is used to redirect to some page in your case ,it is redirecting to registerTeacher.phppage as you have specify in your href attribute.Instead you can do like below :
When below <a href..> is clicked you can put form on registerTeacher.php like below :
<?php
if (isset($_GET['edit'])) {
$id = $_GET['edit'];
$update = true;
$record = mysqli_query($conn, "SELECT * FROM users WHERE id=$id");
if (#count($record) == 1 ) {
$n = mysqli_fetch_array($record);
$username = $n['username'];
$email = $n['email'];
$style = "style='display:block;'";
}
}
?>
<!------- FORM TO EDIT REGISTERED TEACHERS ---------->
<form method="post" action="abcpage.php" <?php echo $style;?>>
<!----- newly added field--->
<input type="hidden" name="id" value="<?php echo $id; ?>">
<div class="input-group">
<label>USER</label>
<input type="text" name="username" value="<?php echo $username; ?>">
</div>
<div class="input-group">
<label>EMAIL</label>
<input type="email" name="email" value="<?php echo $email; ?>">
</div>
<div class="input-group">
<!--------BUTTON----->
<?php if ($update == true): ?>
<button class="btn_update" type="submit" name="update">EDIT</button>
<?php endif ?>
</div>
</form>
Then you can passed this details to your action="abcpage.php".and write like below in that page i.e :
// UPDATE
if (isset($_POST['update'])) {
$id = $_POST['id'];
$username = $_POST['username'];
$email = $_POST['email'];
mysqli_query($conn, "UPDATE users SET username='$username', email='$email' WHERE id=$id");
$_SESSION['message'] = "User edited!";
header("Location: indexAdmin.php?page=professors");
}
?>
Hope this helps !
Note : Also try using prepared statement it is safe an secure.

UTF-8 all the way through
(13 answers)
Closed 7 years ago.
Hello i have been trying to make { View / edit / add Script }
which i got from google..
but the main issue is it's not supporting arabic language [UTF-8] encode
here is the code:
<?php
ini_set('default_charset', 'UTF-8');
setlocale(LC_ALL, 'UTF-8');
date_default_timezone_set('Asia/Riyadh');
error_reporting(0);
require 'database.php';
if ( !empty($_POST)) {
// keep track validation errors
$nameError = null;
$uidError = null;
$actionError = null;
$reasonError = null;
// keep track post values
$name = utf8_encode($_POST['Name']);
$uid = utf8_encode($_POST['uid']);
$action = utf8_encode($_POST['Action']);
$reason = utf8_encode($_POST['Reason']);
// validate input
$valid = true;
if (empty($name)) {
$nameError = 'Please enter Name';
$valid = false;
}
if (empty($uid)) {
$uidError = 'Please enter UID';
$valid = false;
}
if (empty($action)) {
$actionError = 'Please enter action';
$valid = false;
}
if (empty($reason)) {
$reasonError = 'Please enter reason';

Well no idea why it's not working for me
any help will be great <3
You haven't said why it doesn't work. You may need to be more verbose.
Unless you specify it, forms are sent in the user's locale encoding. You need to set your form with an encoding. UTF-8 will allow characters from any region/language:
<form class="form-horizontal" action="create.php" method="post" accept-charset="UTF-8">
Now your $_POST[] elements will be already UTF-8 encoded, so you don't need to convert them. Change them to:
$name = $_POST['Name'];
$uid = $_POST['uid'];
$action = $_POST['Action'];
$reason = $_POST['Reason'];
Make sure the following is present in your file:
header('Content-type: text/html; charset=utf-8');
There's also a meta tag for in the document head.
meta http-equiv="Content-Type" content="text/html; charset=UTF-8"
Make sure your data source/destination is collated for UTF-8.
Then the only other thing it could be is your text editor encoding. Should be UTF-8 without BOM. No matter what is going on in the file, if the file itself isn't UTF-8 then it won't work.
I've been testing a CRUD interface with PHP and SQLSRV driver but i got stuck on the creating part, i can read the data that alredy was added on the database by id, but i cant get to work the create data from PHP to the database, when i press the create Button it clears the inputs and shows the errors. Would like to know if there is something wrong with my code so far.
PHP CODE:
<?php
require 'database.php';
if ( !empty($_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'];
