After a user has registered on my website, I want to display a welcome message on the next page..
I want this to be visible just once.
I tried to do this with session but the problem is - it appears every single time the user is logged in and visits that page...
$message2 = "Congrats!! Your store has been created successfully!";
$_SESSION['message2'] = $message2;
header("location: admin/welcome.php");
Am building with php....but I dont mind using jquery etc for this.
In welcome.php, after the line that prints the message, unset $_SESSION['message2'] or empty it.
Example
echo $_SESSION['message2'];
unset($_SESSION['message2']);
// OR
$_SESSION['message2'] = null;
maybe you can use GET to make it work like this:
header("location: admin/welcome.php?message=$message2");
on welcome.php page
if(isset($_GET['message']) && !empty($_GET['message'])){
echo $_GET['message'];
}
Do you use start_session();
After displaying first you could set a $_SESSION['displayed'] = true;
then checking if this variable is set, to avoid display a second time

it say too many redirect, probably you are into a loop.
I have five unique forms each on a page of HTML. They then go to a PHP file to send the e-mail of data. Next they go to the HTML thank you page. I am hoping to change the heading according to which form they just submitted.
For example, if they submit a review, the should read "Thank you for your review" etc.
Technically all of these are saved as php files but only the e-mail page has php items.
Like <?php echo("<p>". $mail->getMessage()."</p>"); ?>
You should redirect to another php file and pass a parameter on url. Example:
sendemail.php
<?php
/** After send the email, check what kind form is (I don't know how do you check this).
This example is just to show you: */
if ($formType == 'review') {
$type = 'review';
} else if ($formType == 'anothertype') {
$type = 'anothertype';
}
header('Location: /thankspage.php?type=' . $type);
?>
thankspage.php
<?php
$type = $_GET['type'];
if ($type == 'review') {
echo '<h1>Thanks for your review</h1>';
} else if($type == 'anothertype') {
echo '<h1>Thanks for your anothertype</h1>';
}
?>
One way put a hidden field in your forms that'll get passed with the other form data. Then put an if statement on the thank you page and echo the appropriate message.
However, that'll only work either if you change the thank you page to php or change the page that receives and processes the form data to echo the thank you message as well
I have the following code
<?php
if($_SESSION['loggedin']){
echo '<li id="login-btn">Logout</li>';
}
else{
echo '<li id="login-btn">Login</li>';
}
?>
This is inside of the HTML for my Navbar. I want it to where if they are logged in, it will show "Logout", if they aren't logged in, it'll show "Login", (self explanatory)
I have this in my login.php
$loggedin = "";
$_SESSION['loggedin'] = true;
For some reason, no matter what I do, my navbar keeps displaying "Login"? Help please, thank you!
Session are global variables in php...
Session variables are not passed individually to each new page,
instead they are retrieved from the session we open at the beginning
of each page (session_start()).
if you want to access it on different page... you have to add
<?php
session_start();
?>
at the begining .... even in your login.php page
I have following problem, I am trying to set cookies without any success. setcookie(); function returns true so it looks like it setting cookie however when I am trying to access it on the same or following page I get error 'Undefined Index....'
<?
session_start();
ob_start();
echo setcookie("order",$_SESSION['cart'],time()+3600,'/',NULL);
//added to see if Cookie is set
echo "<br/>";
var_dump($_COOKIE);
exit();
if($_GET['paypal'] == 1){
header("Location: /paypal-express-checkout/process.php");
}else{
header("Location: /insert_order.php");
}
ob_end_flush();
exit();
?>
next page follows like this
<?php
session_start();
include_once("../includes/inc_config.php");
include_once("../order.php");
include_once("config.php");
include_once("paypal.class.php");
#region POST
if(!isset($_GET['token'])) //Post Data received from product list page.
{
//Mainly we need 4 variables from an item, Item Name, Item Price, Item Number and Item Quantity.
if(!isset($_COOKIE['order'])){
exit();
}
$paypal_data = '';
$ItemTotalPrice = 0;
$order = unserialize($_COOKIE['order']);
print_r($order);
exit;
You are setting the domain value to NULL. Try leaving the NULL away:
echo setcookie("order",$_SESSION['cart'],time()+3600,'/');
OR set it to your domain:
echo setcookie("order",$_SESSION['cart'],time()+3600,'/',".yourdomain.com");
I would var_dump or print_r the $_COOKIE variable before I make a decision that it's not getting passed through. Holding that thought once you setcookie something gets registered into the $_COOKIE variable for sure.
I agree with the statements above since you only can access $_COOKIE on the next refresh but there is another way to do it to make your form or page more interactive.
I would register the cookie and use a php page refresh (display a working... div while thats happening) then come back to the page and try to do what you originally tried doing. Very basic but pretty much straight forward.
I am redirecting to a different page with Querystring, say
header('location:abc.php?var=1');
I am able to display a message on the redirected page with the help of querystring value by using the following code, say
if (isset ($_GET['var']))
{
if ($_GET['var']==1)
{
echo 'Done';
}
}
But my problem is that the message keeps on displaying even on refreshing the page. Thus I want that the message should get removed on page refresh i.e. the value or the querystring should not exist in the url on refresh.
Thanks in advance.
You cannot "remove a query parameter on refresh". "Refresh" means the browser requests the same URL again, there's no specific event that is triggered on a refresh that would let you distinguish it from a regular page request.
Therefore, the only option to get rid of the query parameter is to redirect to a different URL after the message has been displayed. Say, using Javascript you redirect to a different page after 10 seconds or so. This significantly changes the user experience though and doesn't really solve the problem.
Option two is to save the message in a server-side session and display it once. E.g., something like:
if (isset($_SESSION['message'])) {
echo $_SESSION['message'];
unset($_SESSION['message']);
}
This can cause confusion with parallel requests though, but is mostly negligible.
Option three would be a combination of both: you save the message in the session with some unique token, then pass that token in the URL, then display the message once. E.g.:
if (isset($_GET['message'], $_SESSION['messages'][$_GET['message']])) {
echo $_SESSION['messages'][$_GET['message']];
unset($_SESSION['messages'][$_GET['message']]);
}
Better use a session instead
Assign the value to a session var
$_SESSION['whatever'] = 1;
On the next page, use it and later unset it
if(isset($_SESSION['whatever']) && $_SESSION['whatever'] == 1) {
//Do whatever you want to do here
unset($_SESSION['whatever']); //And at the end you can unset the var
}
This will be a safer alternative as it will save you from sanitizing the get value and also the value will be hidden from the users
There's an elegant JavaScript solution. If the browser supports history.replaceState (http://caniuse.com/#feat=history) you can simply call window.history.replaceState(Object, Title, URL) and replace the current entry in the browser history with a clean URL. The querystring will no longer be used on either refresh or back/previous buttons.
When the message prompt ask for a non exsisting session. If false, show the message, if true, do nothing. session_start(); is only needed, if there is no one startet before.
session_start();
if ($_GET['var']==1 && !isset($_SESSION['message_shown']))
{
$_SESSION['message_shown'] = 1;
echo 'Done';
}
Try this way [Using Sessions]
<?php
//abc.php
session_start();
if (isset ($_GET['var']))
{
if ($_GET['var']==1)
{
if(isset($_SESSION['views']))
{
//$_SESSION['views']=1;
}
else
{
echo 'Done';
$_SESSION['views']=1;
}
}
}
?>
Think the question mean something like this?
$uri_req = trim($_SERVER['REQUEST_URI']);
if(!empty($_SERVER['REQUEST_URI'])){
$new_uri_req = str_replace('?avar=1', '?', $uri_req);
$new_uri_req = str_replace('&avar=1', '', $new_uri_req);
$pos = strpos($new_uri_req, '?&');
if ($pos !== false) {
$new_uri_req = str_replace('?&', '?', $new_uri_req);
}
}
if( strrchr($new_uri_req, "?") == '?' ){
$new_uri_req = substr($new_uri_req, 0, -1);
}
echo $new_uri_req; exit;
You can use then the url to redirect without vars. You can also do the same in js.
str_replace() can pass array of values to be replaced. First two calls to str_replace() can be unified, and filled with as many vars you like that needs to be removed. Also note that with preg_replace() you can use regexp that can so manage any passed var which value may change. Cheers!
