PHP GET id from articles.php - php

Question

I have an Articles.php page and a Single.php page. Articles.php runs a foreach loop listing all of the articles. The href anchor for each article is:
<a href="single.php?id=<?php echo $article['id'];
When the article link is click the URL becomes:
example.com/single.php?id=*ID*
I am having trouble grabbing that article ID on the single page to show the MySQL row specific to that id. The following was suggested:
$id = filter_var($_GET['id'] ?? false, FILTER_VALIDATE_INT);
if($id !== false){
//show the article, i.e. select * from .... where id = id ...
echo "WORKING";
}else{
//show the error like 404
echo "ERROR";
}
Should this be:
$id = $_GET($article['id'])
I am having trouble making this work.

Answer 1

Send value to another page using..
Link //missing php close tag here
Then get it using
$id = $_GET['id'];

Answer 2

ok lets try this.
on page 1 => article.php
# we assume
database query here
$query = mysqli_query(//query here);
// we then use a while loop
while($q = $query->fetch_array())
{
echo ''.$q['article_name'].'';
}
ok on page single.php
# we now have example.com/single.php?id=1 eg.
// there are many ways to grab the id
# option 1
// inside single.php
// method 1
$article_id = isset($_GET['id']) ? (int) $_GET['id'] : "";
// method 2
$article_id2 = "";
if(isset($_GET['id']))
{
$article_id2 = $_GET['id'];
}
// now you have the value from the GET method within your local variable scope
// so choose any of the method above
// both works
hope this helps?

As Hek mat said you missed the Clossing tags:

But you your code is also not correct $_GET['id'] is giving always a string "1" not a int 1 and if the id is not set this would cause an error.
So try this:
if(isset($_GET['id']) && intval($_GET['id']) > 0){
$id = intval($_GET['id']); // now work with $id its an int now
//show the article, i.e. select * from .... where id = id ...
echo "WORKING";
}else{
//show the error like 404
echo "ERROR";
}
