Add 5 to a variable when a button is clicked, and re-run a for loop

Posted on 16th Feb 2014 by admin

So I'm making a feedback sort of section on a website with MySQL and PHP, I've gotten the script to do everything I want except for this. I want the script to only show 5 at a time (which i have accomplished no problem), but I'm also trying to make it so that when the user clicks a button it will show the next 5 records in the database so they can view all records, but only 5 at a time. (I hope this makes sense). So I need the button to add 5 to my $start variable, and then re-run my for loop.


$start = 0;
echo $start . "<br /><br />";
$result2 = mysql_query("SELECT * FROM testtable LIMIT $start,5") or die(mysql_error());
$row2 = mysql_fetch_array($result2);

for($counter = 1; $counter <= 5; $counter += 1)
{

echo $row2['ID'] . "<br />";
echo "&nbsp;&nbsp;Subject:<b><font color='red'>&nbsp;" . $row2['Subject'] . "</font></b>";
echo "<br />Message:&nbsp;<b>" . $row2['Message'] . "</b><br /><br />";
$row2 = mysql_fetch_array($result2);

}

mysql_close($con)
?>


<br />

<form>
<input type="button" value="submit" onclick="<?php $start += 5; ?>" />
</form>

<?php echo $start; ?>

Any help would be greatly appreciated!
