Issues making a template loops with variables - php

Question

I'm trying to make a simple blog to my site and there is no tutorial of how to make one properly, so i'm trying to make one from scratch. My problem right now is to display a template of posts in a loop with variables. Here are the columns of my table:
Table blog
id
user_id
date
title
content
Code of variables:
<?php
// query //
$sql = mysql_query("SELECT id, user_id, date, title, content FROM blog");
$row = mysql_fetch_array($sql);
// variables //
$user_id = $row['user_id']; //only the id, not the name
$date = $row['date'];
$title = $row['title'];
$content = $row['content'];
// get user_id name //
$sql2 = mysql_query("SELECT name FROM users WHERE id = '$user_id'");
$row2 = mysql_fetch_array($sql2);
$author = $row2['name']; //last variable
?>
What i'm trying to do, is to display them all descendant from id value from the next template vertically:
<div id="container">
<div align="center" style="background-color:gray"><b><?php echo $title;?></b></div>
<div align="right">Author: <?php echo $author;?> Date: <?php echo $date;?></div>
<div><?php echo $content;?></div>
</div>
<hr>
How could i loop the template with different variables values in a simple page?

Answer 1

try this:
<?php
// query //
$sql = mysql_query ( "
SELECT b.id, b.user_id, b.date, b.title, b.content, u.name
FROM blog b, users u
WHERE b.user_id = u.id
ORDER BY b.id DESC" );
while ( $row = mysql_fetch_array ( $sql ) ) {
// variables //
$user_id = $row ['user_id']; // only the id, not the name
$date = $row ['date'];
$title = $row ['title'];
$content = $row ['content'];
$author = $row ['name']; // last variable
?>
<div id="container">
<div align="center" style="background-color: gray">
<b><?php echo $title;?></b>
</div>
<div align="right">Author: <?php echo $author;?> Date: <?php echo $date;?></div>
<div><?php echo $content;?></div>
</div>
<hr>
<?php
}
?>
first make one query for info if you have a lot of rows it will eat resources
SELECT b.id, b.user_id, b.date, b.title, b.content, u.name
FROM blog b, users u
WHERE b.user_id = u.id
ORDER BY b.id DESC
then you need to loop the query using:
while ( $row = mysql_fetch_array ( $sql ) ) {}

Answer 2

First you need to put your blog table in an array:
$sql = mysql_query("SELECT id, user_id, date, title, content FROM blog");
while($row = mysql_fetch_array($sql)) {
$blog[] = $row;
}
Then, in the template:
<div id="container">
<div align="center" style="background-color:gray"><b><?php echo $title;?></b></div>
<div align="right">Author: <?php echo $author;?> Date: <?php echo $date;?></div>
<div><?php
foreach($blog as $val) {
echo "<h1>".$val['title']."</h1>"M
echo $val['content'];
}
?></div>
</div>

Answer 3

$records = mysql_fetch_array($sql);
$blogs_table = '<table> <tr> <th>User id</th> <th>Date</th> <th>Title</th> <th>Content</th></tr>';
foreach($records as $row) {
$blogs_table .= '<tr>';
$blogs_table .= '<td>' . $row ['user_id'] .'</td>';
$blogs_table .= '<td>' . $row ['date'] .'</td>';
$blogs_table .= '<td>' . $row ['title'] .'</td>';
$blogs_table .= '<td>' . $row ['content'] .'</td>';
$blogs_table .= '</tr>';
}
$blogs_table .= '</table>';
At last you can print your $blogs_table table to any where like,
<div align="right"><?php echo $blogs_table ?></div>
