Pass parameters var/value to second page Php - php

Question

I am trying to pass some parameters vars and variables from one page x to another page y
My parameterized portion looks like:
x?path=1&edu=4&cert=
How can I pass these values easily to another page using php?
Note: often times cert var has no value.
For example:
I have a file x.php that is generating a url like: xx.xxx.xxx.xxx/p?path=1&edu=4&cert= . I need to then use this url in y.php - how can I do this?
Note: I am unable to use a framework for this application
Thanks

Answer 1

When receiving the parameters in page x, save them in variables and add them in the link to the page y. There are better ways but they depend on exactly what you want to do.
Simple example below.
x.php?path=1&edu=4&cert=
<?php
$path=$_GET['path'];
$edu=$_GET['edu'];
$cert=$_GET['cert'];
$params = "?path=".$path."&edu=".$edu."&cert=".$cert;
?>
Link to page Y with params obtained from page X
The result will be y.php?path=1&edu=4&cert=
It doesn't matter if you don't have a value in cert, it will pass as cert=

Answer 2

try use header location
$path=$_GET['path'];
$edu=$_GET['edu'];
if(!isset($_GET['cert'])) header("Location: y.php?edu={$edu}&path={$path}");
else $cert = $_GET['cert'];

Answer 3

I'm not to understand what you want but try this :
x.php
<?php
$url = 'http:localhost/test.php?path=1&edu=4&cert=';//generated url
parse_str(parse_url($url)['query']);//get parameter on url
include("y.php");
y.php
<?php
//!\ you must secure this value /!\
var_dump($path);
var_dump($edu);
var_dump($cert);

Answer 4

Are u submitting any form???If you are going from x.php to y.php through some event like button click then you can do an ajax call and easily can receive the parameters in the other page.
like <input name="" type="button" onclick="showHint($x);" value="click on me!" id="start" />//wher $x=1 your value
<div id="txtHint"></div>
You can write function as
<script>
function showHint(path) {
if (path.length == 0) {
document.getElementById("txtHint").innerHTML = "";
return;
} else {
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
document.getElementById("txtHint").innerHTML = xmlhttp.responseText;
}
}
xmlhttp.open("GET", "y.php?p=" + path, true);
xmlhttp.send();
}
}
</script>`
Now in y.php you can catch the param as
$path= $_REQUEST["p"];
Like this you can pass the params from one php page to another.
I don't know whether you want this kind of thing or something else.
