PHP Fetching Data From Specific MySQL Row - php

Question

Recently I've set it up so I can update my sites news via my administration panel and now I've been seeking across the web for a solution to print specific lines.
$query = "SELECT * FROM BananzaNews";
$result = mysql_query("SELECT * FROM BananzaNews", $con);
$num_rows = mysql_num_rows($result);
The above tells me how many rows I have and for my five most recent which will be shown on my home page, I want to fetch the data for $num_rows, $num_rows -1, $num_rows -2, $num_rows -3 and $num_rows -4.
The data to fetch;
title
newsDate
imagePath
content
websitePath
My current dummy filled code is the following dubplicated five times;
<div class="Feed">
<div class="Img"><img alt="" src="http://www.davidreneke.com/wp-content/uploads/2013/12/News-Briefs.png"></div>
<div class="Title">My Testing Title</div>
<div class="Date">
<div class="Day">22</div>
<div class="Month">Jan</div>
<div class="Year">2015</div>
</div>
<div class="Brief">Vivamus consectetur et sapien vel rhoncus. Maecenas gravida posuere hendrerit. Duis lobortis justo ac justo malesuada commodo. Proin iaculis, erat ac aliquet eleifend, neque felis tristique turpis, at dictum tellus lectus et lorem. Nunc turpis enim, auctor sed purus nec.</div>
<div class="More"></div>
<div class="Divider"></div>
</div>
My PHP
<?php
$query = 'SELECT title,newsDate,imagePath,content,websitePath FROM BananzaNews ORDER BY id Desc LIMIT 5';
$resultSe = mysql_query($query, $con);
if (mysql_num_rows($result) > 0) {
while($row = $resultSet->fetchRow ( DB_FETCHMODE_OBJECT )){
echo "<div class=\"Feed\">
<div class=\"Img\"><img alt=\"\" src=\"" $row->imagePath "\"></div>
<div class=\"Title\">" $row->title "</div>
<div class=\"Date\">
<div class=\"Day\">" $row->newsDate "</div>
<div class=\"Month\">" $row->newsDate "</div>
<div class=\"Year\">" $row->newsDate "</div>
</div>
<div class=\"Brief\">" $row->content "</div>
<div class=\"More\">" $row->websitePath "</div>
<div class=\"Divider\"></div>
</div>";
}
}
?>

Answer 1

You want to use MySQL's ORDER BY. You don't need to use num_rows to get the 5 latest posts. Simply order them by their id columns and then LIMIT it to 5. If they don't have id columns, they should have an id column that auto_increments and is a PRIMARY KEY. With that, this code will help you:
//Load your mysql_query into a variable SELECTing not *, but only the rows you need.
$query = mysql_query("SELECT title, newsDate, imagePath, content, websitePath FROM BananzaNews ORDER BY newsid DESC LIMIT 5") or die(mysql_error()); //<- Error handling.
//This loads up each row into an associative array into the variable $row
//So, $row['title'] will be equal to the 'title' column at that row in your database
while($row = mysql_fetch_array($query)){
//Output your repeating code
//Notice how I've used concat operators (dots) to stop the echo and start it again.
//I'd recommend looking those up if you haven't.
echo
'<div class="Feed">
<div class="Img"><img alt="" src="'.$row['imagePath'].'"></div>
<div class="Title">'.$row['title'].'</div>
<div class="Date">
<div class="Day">22</div>
<div class="Month">Jan</div>
<div class="Year">2015</div>
</div>
<div class="Brief">'.$row['content'].'</div>
<div class="More"></div>
<div class="Divider"></div>
</div>';
}
I would actually also use mysqli over mysql, mainly because it's well... mysql-improved. Do look into it, I highly recommend it. Even better, use PDO.
I hope this was helpful!

Answer 2

if you want to get the data to fetch run your query in while loop
$result=mysqli_query("select * from table_name order by id desc limit 0,5")
while($each=mysqli_fetch_array($result ))
{
//your code goes here
}

Answer 3

Use this query it will work for you
$query = 'SELECT title,newsDate,imagePath,content,websitePath FROM BananzaNews ORDER BY id Desc LIMIT 5';
$resultSet = mysql_query($query);
if (mysql_num_rows($query) > 0) {
while($row = mysql_fetch_array($resultSet)){
echo $row['title'];
echo $row['newsDate'];
}
}
You can loop your data like this.

Answer 4

Try this it will work :
1. use mysqli or pdo instead of mysql extension. It already depreciated and will be remove in future.
2. Loop your result set to get all the data from the table.
<?php
$result = mysqli_query($con,"SELECT * FROM BananzaNews LIMIT 0,5");
$rs = mysqli_fetch_array($result);
?>
<table>
<?php
do
{
?>
<tr>
<td><?php echo $rs['title']; ?></td>
<td><?php echo $rs['newsDate']; ?></td>
<td><?php echo $rs['imagePath']; ?></td>
<td><?php echo $rs['content']; ?></td>
<td><?php echo $rs['websitePath']; ?></td>
</tr>
<?php
}while($rs = mysqli_fetch_array($result));
?>
