Q:

Pass variables between two PHP pages without using a form or the URL of page

Hi everyone,

I have a question regarding passing variables between two PHP pages without using a form or the URL of the page. I'm currently working on a project where I need to send data from one PHP page to another without relying on a form submission or including the variables in the URL.

I understand that typically, we use forms or query parameters in the URL to pass data between pages. However, in this case, I want to keep the process seamless and not expose the data in the URL or rely on user input.

To give you some context, I have a PHP page where I collect some user input and perform some calculations on it. I want to pass the result of these calculations to another PHP page without any user intervention.

Is there a way to achieve this? I've explored using session variables, but it seems like they are tied to a specific user session and won't work for my scenario.

I appreciate any insights or suggestions on this matter. Thank you in advance for your help!

Hey there,

I faced a similar challenge not too long ago, where I needed to pass variables between PHP pages without relying on forms or the URL. After digging deeper into this, I found that using session variables could be a viable option for achieving this.

On the first PHP page, I stored the variable in a session variable like this:

php
session_start();
$_SESSION['myVariable'] = $myValue;


Then, on the second PHP page, I retrieved the session variable value as follows:

php
session_start();
if(isset($_SESSION['myVariable'])) {
$myValue = $_SESSION['myVariable'];
// Use $myValue as needed
}


In my experience, this method worked well in maintaining the state between the two pages. Session variables are stored server-side, alleviating any security concerns related to the URL or exposing data. However, do note that session variables are tied to a specific user session, so if you need to pass variables between different user sessions, this approach may not be suitable.

I hope this solution helps you in your project. If anyone else has different experiences or alternative suggestions, feel free to chime in!

Hey everyone,

I went through a similar situation where I needed to pass variables between PHP pages without resorting to forms or the URL. I found a solution using the PHP `$_SESSION` variable, which worked well for my specific scenario.

On the first PHP page, I stored the variable in the session like this:

php
session_start();
$_SESSION['myVariable'] = $myValue;


Then, on the second PHP page, I retrieved the session variable value like this:

php
session_start();
$myValue = $_SESSION['myVariable'];
// Use $myValue as required


What I particularly like about using session variables in this scenario is that they can hold various types of data, not just simple values. I could store arrays, objects, or even complex data structures if needed. Just ensure you start the session (`session_start()`) on both PHP pages before accessing or modifying the `$_SESSION` variable.

However, it's essential to remember that session variables are specific to each user session and stored on the server. If your application requires passing variables across different sessions or multiple users simultaneously, this approach may not be suitable.

I hope this solution helps you out, and I'm open to hearing about other approaches or experiences from the community if there are alternative methods worth exploring.

I've encountered a similar situation before where I needed to pass variables between PHP pages without using forms or the URL. After some research, I found that one possible solution is to use cookies.

In my case, I set a cookie on the first page with the desired variable value like this:

php
setcookie("myVariable", $myValue, time()+3600); // Expiring in 1 hour


Then, on the second PHP page, I retrieve the cookie value like this:

php
if(isset($_COOKIE["myVariable"])){
$myValue = $_COOKIE["myVariable"];
// Use $myValue as needed
}


Please note that you need to ensure both pages are hosted on the same domain for cookies to work properly.

This method worked well for my scenario, where I wanted to pass a simple value between pages without exposing it in the URL. However, keep in mind that cookies can be manipulated by users, so it might not be the most secure option for sensitive data.

I hope this helps you in finding a solution for your specific case. If anyone else has alternative suggestions or improvements to this method, feel free to share!
