How to redirect to the same page in PHP
(9 answers)
Closed 8 months ago.
After submitting information to my database, I want to refresh the page to show those changes, as when the form has been processed. The page "reloads" after submission but does not reflect the changes, so I assumed I would need to add a refresh command in when submit is pressed, but it seems to be too quick?
So I added a refresh time, but even cranking it up to 50 I got the same result.
If I press the button twice it refreshes with the correct information. Is there a better way to do this?
<?php

$stmt->execute(array(":id"=>$id));
$userRow=$stmt->fetch(PDO::FETCH_ASSOC);

You are doing it wrong, you have to process the form submission BEFORE showing the HTML. PHP is being executed line-by-line so in your case you are firstly showing the data and then you are checking if the form is submitted. Simply move this code up where the rest of your PHP code is located (you can even remove the refresh stuff command):
if(isset($_POST['submit'])){
header('Location: '.$_SERVER['REQUEST_URI']);
die;
}
Edit:
People invented MVC because of cases like yours when you are mixing HTML and PHP and wonder why things don't work. Keep your PHP code at the top of the files, try not to write PHP code anywhere inside HTML, you will save yourself a lot of trouble. And also, use exit after calling header to stop code execution any further. Here is an updated version of your code, simplified and more "algorithmic" (I hope you do see and understand how the code flow goes):
<?php
ini_set('display_errors',1);
error_reporting(E_ALL);
include_once '../includes/conn.php';
if(!$user->is_loggedin()){
$user->redirect('../users/login.php');
}
$id = $_SESSION['session'];
$stmt = $conn->prepare("SELECT * FROM users WHERE id=:id");
$stmt->execute(array(":id"=>$id));
$userRow=$stmt->fetch(PDO::FETCH_ASSOC);
if (isset($_POST['submit'])) {
$location = isset($_POST['location']) ? $_POST['location'] : null;
$about = isset($_POST['about']) ? $_POST['about'] : null;
$title = isset($_POST['title']) ? $_POST['title'] : null;
$sql_part = array();
$prepare = array();
if ($location) {
$sql_part[] = 'location = :location';
$prepare[':location'] = $location;
}
if ($about) {
$sql_part[] = 'about = :about';
$prepare[':about'] = $about;
}
if ($title) {
$sql_part[] = 'title = :title';
$prepare[':title'] = $title;
}
$prepare[':id'] = $id;
if (count($sql_part)) {
$sql = 'UPDATE users SET ';
$sql .= implode(', ', $sql_part);
$sql .= ' WHERE id = :id';
$stmt = $dbh->prepare($sql);
if ($stmt) {
// Find another way too pass these through the refresh
// $result = $stmt->execute($prepare);
// $count = $stmt->rowCount();
header('Location: '. $_SERVER['REQUEST_URI']);
exit;

I managed to get the desired result by adding header('Location: ./editprofile.php'); after the database was updated. See bellow:
if($title!=''){
$sql = "UPDATE users SET title=:title WHERE id=:id";
$stmt = $conn->prepare($sql);
if($stmt == false){
$error = "User Title update failed. Please try again.";
}
$result = $stmt->execute(array(":title"=>$title, ":id"=>$id));
if($result == false) {
$error = "User Title update failed. Please try again.";
}
$count = $stmt->rowCount();
}
After:
if($title!=''){
$sql = "UPDATE users SET title=:title WHERE id=:id";
$stmt = $conn->prepare($sql);
if($stmt == false){
$error = "User Title update failed. Please try again.";
}
$result = $stmt->execute(array(":title"=>$title, ":id"=>$id));
if($result == false) {
$error = "User Title update failed. Please try again.";
}
$count = $stmt->rowCount();
header('Location: ./editprofile.php');
}
just use JavaScript's-
window.location.reload().
In PHP you can use-
$page = $_SERVER['PHP_SELF'];
$sec = "10";
header("Refresh: $sec; url=$page");

whatever I enter I get the same error "all fields are required" but this error should appear only when field/s is empty.
I have other error should appear when I enter incorrect details but I keep only getting the first error.
I'm a beginner and I had one hour reviewing my code but I still can't solve it by myself :/
<?php
session_start();
include_once('../includes/connection.php');
if (isset($_SESSION['logged_in'])){
//display index
} else {
if (isset($_POST['username'], $_POST['password'])){
$username = $_POST['username'];
$password = $_POST['password'];
if (empty($username) or ($password)) {
$error = 'All fileds are required';
}else {
$query = $pdo->prepare("SELECT * FROM user WHERE user_name = ? AND user_password = ? ");
$query->bindValue(1, $username);
$query->bindValue(2, $password);
$query->execute();
$num = $query->rowCount();
if ($num == 1) {
//user entered correct details
}else {
// user enterde false details
echo $error = 'Incorrect details!';

I am trying to creat a crud application using PHP, I have succeeded to display my data table from postgres but when i try i got some errors. this is my code :
<?php require 'database.php'; $id = null; if ( !empty($_GET['Code_Espece'])) { $id = $_REQUEST['Code_Espece']; } if ( null==$id ) { header("Location: index.php"); } if ($_SERVER["REQUEST_METHOD"] == "POST" && !empty($_POST)) {
$firstnameError = null;
if (isset($_POST['Nom_Scien'])) {
$firstname = $_POST['Nom_Scien'];
}
$valid = true;if (empty($firstname)) { $firstnameError = 'Please enter firstname'; $valid = false; }
if ($valid) { $pdo = Database::connect(); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = 'UPDATE espece SET Nom_Scien = ? WHERE Code_Espece = ?';
$q = $pdo->prepare($sql);
$q->execute(array($firstname));
Database::disconnect();
header("Location: index.php");
}
}else {
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

How to redirect to the same page in PHP

I managed to get the desired result by adding header('Location: ./editprofile.php'); after the database was updated. See bellow:
if($title!=''){
$sql = "UPDATE users SET title=:title WHERE id=:id";
$stmt = $conn->prepare($sql);
if($stmt == false){
$error = "User Title update failed. Please try again.";
}
$result = $stmt->execute(array(":title"=>$title, ":id"=>$id));
if($result == false) {
$error = "User Title update failed. Please try again.";
}
$count = $stmt->rowCount();
}
After:
if($title!=''){
$sql = "UPDATE users SET title=:title WHERE id=:id";
$stmt = $conn->prepare($sql);
if($stmt == false){
$error = "User Title update failed. Please try again.";
}
$result = $stmt->execute(array(":title"=>$title, ":id"=>$id));
if($result == false) {
$error = "User Title update failed. Please try again.";
}
$count = $stmt->rowCount();
header('Location: ./editprofile.php');
}
just use JavaScript's-
window.location.reload().
In PHP you can use-
$page = $_SERVER['PHP_SELF'];
$sec = "10";
header("Refresh: $sec; url=$page");
I have created a form that should submit some content in the database. A make an random numberstring and then when a submit I want the content insert into database. But before submit the random numbers is repeated and I got a new one. How to eliminate that?
<?php
include_once('../includes/connection.php');
$random = rand(1000, 2000)
$dedu = $pdo->prepare("UPDATE users SET user_password ='$random'");
$password = $_POST['password'];
$query = $pdo->prepare("SELECT * FROM users WHERE user_password = ?");
$query->bindValue(1, $password);
$dedu->execute();
$query->execute();
$num = $query->rowCount();
if ($num == 1) {
if (isset($_POST['title'], $_POST['content'])) {
$title = $_POST['title'];
$content = nl2br($_POST['content']);
if (empty($title) or empty($content)) {
$error = 'All fields are requried';
} else {
$query = $pdo->prepare('INSERT INTO articles (article_title, article_content) Values (?, ?)');
$query->bindValue(1, $title);
$query->bindValue(2, $content);
$query->execute();
$msg = 'You added the following article!';
}
}
} else {
$error = 'Incorrect details!';
}

Not sure if i understand correctly what you want to achieve but try putting
$random = rand(1000, 2000)
after
$query->execute();
Use this cookie concept in your file
<?php
$cookie_name = "user";
$cookie_value = "John Doe";
setcookie($cookie_name, $cookie_value, time() + (86400 * 30), "/"); // 86400 = 1 day
?>
<html>
<body>
<?php
if(!isset($_COOKIE[$cookie_name])) {
//dont do anything
} else {
$random = rand(1000, 2000);
}........proceed with your code
?>
if(isset($_POST['password']))$password = $_POST['password'];
else $random = rand(1000, 2000);
I solved it with a session!
If the session is false the rand function runs and the session is set to true. When the page reloads(submit pressed) the session is true so all the other cod runs. In the end of the code (if session is true) the session is destroyd. Because If the user want a new rand the reload the page and the rand function runs again.
