Array Results in PHP - php

Question

Is it possible to limit the results shown from a MYSQL database?
At the moment the results are shown in a html table, how do I only show the newest entries?
<?php
$con = mysql_connect("localhost","cl49-XXX","XXX");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("cl49-XXX", $con)or die("Unable to select database");
$result=mysql_query("SELECT * FROM products") or die('You need enter a category');
echo "<tr>"; // first row beginning
for ($i = 1; $i <= mysql_num_rows($result); $i++)
{
$row = mysql_fetch_array($result);
$prodname = $row['prodname'];
$prodID = $row['prodID'];
$catagory = $row['catagory'];
echo "
<td>$prodID</td>
<td>$prodname</td>
<td>$catagory</td>
<td>
<a href=deleteproduct.php?q=$prodID' class='btn mini red'>
<i class='icon-trash'></i> Delete Item</a>
</td>";
echo "</tr><tr>"; // it's time no move to next row
}
echo "</tr>"; // last row ending
?>

Answer 1

Just switch your query to something like this!
$result=mysql_query("SELECT * FROM products LIMIT 0,10")or die('You need enter a catagory' );
LIMIT 0,10 will show the first 10 results from your DB.
You could even order it by a specific element in your DB.
$result=mysql_query("SELECT * FROM products ORDER BY objectName LIMIT 0,10")or die('You need enter a catagory' );

Good luck!

Your question Consists of two parts.
First part: Is it possible to limit the results shown from a MYSQL database?
you can do that by using limitword inside the query.
Example:
mysql_query("SELECT * FROM products limit 1, 5");
The previous code say select all products and start from the product one and show me 5 products only.
Second part: how do I only show the newest entries ?
You can do that by, must first create column called date to your products table, then when add new product, store the time by using time() function into date column.
Then when you want to show the products order by newest products, you can use order by sentence.
Example:
mysql_query("SELECT * FROM products order by date ASC limit 1, 5");
To apply these words on your code, only need to
Add new column in your products table and call it date.
Then change the query that adds the products to products table to add also
the time to the date column by using time() function.
INSERT INTO tableName(date) VALUES('".time()."');
Show the products sorted order by newest by modify the query to
$result=mysql_query("SELECT * FROM products ORDER BY date ASC LIMIT 0, 15") or die('You need enter a category');

Answer 3

First of all, while you're still new, you should look into PDO/Prepared statements instead of mysql_ functions.
Also, you can do this for your SQL:
$result=mysql_query("SELECT * FROM products ORDER BY name DESC LIMIT 0,10")or die('You need enter a catagory ' );
'name' being the name of your products/row name you wish to sort it by

Answer 4

just add a counter and when the counter hits a number use:
break;
to jump out the loop.
for example
for ($i = 1; $i <= mysql_num_rows($result); $i++)
{
if ($i==3) break;
}
Of course you could better limit the loop itself:
use:
for ($i = 1; $i <= 4; $i++)
or use the LIMIT option in the SQL-query
