create dynamic link from Mysql table - php

Question

Im trying to create dynamic links from some post inside a database table,
but i cant figure out how to create the link, when the user is already logged in.
I think something like this.
<?php $articles = new Articles();
foreach($articles->fetch_user_article($_GET['uid']) as $article) :?>
<?php echo $article['title'];?>
<?php endforeach ?>
This gives me a link that looks like this
edit_articles.php?uid=5&article=213
The article id:s are correct from the DB table.
Now my edit_articles.php file
$articles = new Articles();
$article = $articles->fetch_user_article($_GET['uid']);
echo $article['text'];
But when im reach the edit_articles.php file i get
Undefined index: text
And my function
function fetch_user_article($uid){
$uid = (int)$uid;
$query = $this->link->query ("SELECT id, title,text FROM blog WHERE user_id = '{$uid}' ");
$tweet = array();
while(($row = $query->fetch(PDO::FETCH_ASSOC)) !== FALSE) {
$tweet[] = $row;
}
return $tweet;
}

Your function fetch_user_article is returning more than one article.
Use like this to fecth all articles.
$articles = $articles->fetch_user_article($_GET['uid']);
foreach ( $articles AS $article ) {
echo $article['text'];
}
If you want fetch_user_article to return only one article, then the field user_id of table blog should be unique.
Or you will have to rewrite the query
SELECT id, title,text FROM blog WHERE user_id = '{$uid}'
so it gives you only one result, something like:
$article_id = $_GET['article'];
SELECT id, title,text FROM blog WHERE id = '{$article_id}'
