Personalized content - php

Question

I would like to, clicking on a link, showing a content personalized.
<div class="tab_event">
<?php
do{
echo'
<table class="preview_event">
<td class="date_event">
'.$row["Date"].'
</td>
<td class="title_event">
<p>'.$row["Title"].'<br></p>
Read more !
</td>
</table>
';
} while ($row = $query->fetch(PDO::FETCH_ASSOC));
?>
My program consist at doing a "preview" of some articles from the database.
And when you click on "read more" i would like that, automatically, you get a page where the all article is written.
But I don't have any ideas about how to do it, bcs i don't want to create a page manually for each article.
Does anyone have any idea about how to do ?
Thanks

Answer 1

To achieve what you want, you need to generate a href to another/same PHP powered page along with a query parameter with some value which uniquely identifies the article in your database.
Assuming your database table structure is similar to
| Id | Date | Title |
|----|------------|------------------------|
| 1 | 0000-00-00 | Some catchy post title |
| 2 | 0000-00-00 | Yet another post title |
| 3 | 0000-00-00 | Some other title? |
I will use $row["Id"] using the above table structure
<div class="tab_event">
<?php
do {
echo '
<table class="preview_event">
<td class="date_event">
'.$row["Date"].'
</td>
<td class="title_event">
<p>'.$row["Title"].'<br></p>
Read more !
</td>
</table>';
} while ($row = $query->fetch(PDO::FETCH_ASSOC));
?>
Now access the aid parameter on your linked script (showArticle.php) to fetch the article from databse
<?php
if (!empty($_GET['aid']) {
// escape and verify value of `$_GET['aid']`
// fetch and return article from database using the `$_GET['aid']` parameter
} else {
// tell the user no `Id` was provided
}
?>

It's quite an easy task, first of all, you need to modify your table page, and edit the read more link this :
Read more !
Where article_idis whatever record's identification you wanna use to store that information when clicking the link, for example the article's id field in the database, now you create a read.php page, which will change its content based on the article's id in the link, so you only need to create that and not one page for each article.
Then in read.php you retrieve that information from the URL so that you can query the database with the correct article's ID and show its content:
...
...
$article_id = $_GET['article'];
// then you query the database using that variable (using whatever method you prefer, this in just an example)
$query = $db->prepare("SELECT title, date, content FROM articles WHERE articles.id = " . $article_id);
$query->fetch(PDO::FETCH_ASSOC);
This way you can retrieve the single's article information and show them on the read.php page , creating only one page which changes its content based on which link you click.
Also, worth mention that you should remove that do...while, for and foreach loops are way more elegant.
One example would be (assuming that the variable containing the results is called $rows) :
<table> <!-- table tag outside of the loop, otherwise for each article a table is created, which is wrong -->
<tbody>
<?php
foreach($rows as $article) {
echo "<tr>"; // since we need one row for each article, we include the tr tag in the loop
echo "<td>".$article['title']."</td>";
echo "<td>".$article['date']."</td>";
echo "<td>".$article['author']."</td>";
...
...
echo "</tr>"; // and we close the row
}
?>
</tbody>
