Help -- SELECT Function PHP Script

[ee222]

Hello,

I have a web page which people can post their messages on it. The messages show on the page are from the old time to the recent time. You can select the pages from page 1 to the last page.

My question is how to change the messages order, so the message "page 1" show the most recent messages first instead the old messages. For example, the recent messages are in the page 1, then page 2...

Here is the web address URL: Wish Web Site .
And here is part ot the SELECT function in PHP script. Could you please tell me how to change(rewrite) the functions? Thank you.

<SELECT NAME="page" style="font-size: 7pt ;font-family: Verdana; background:#808080 url(''); color:#ececec"
onChange="ace.submit();" STYLE="BACKGROUND:#808080;COLOR:#ececec"> <?
if($wishnum%$show_num==0)
$zpage=(int)($wishnum/$show_num);
else
$zpage=(int)($wishnum/$show_num)+1;
for($i=1;$i<=$zpage;$i++){
if($page!=$i){
echo"<option value=$i>page $i</option>";
}
else{
echo"<option value=$i selected>page $i</option>";
}
}
?></SELECT>

Where are the messages being stored? If they are in a database, you can just do a "SORT BY date DESC"

[ee222]

It doesn't have a database or SQL. All the messages are store in one directory only.

You can use scandir to return the names of all the files in the directory: PHP: scandir - Manual

and then for each file you can get the last modified date and time using filemtime: PHP: filemtime - Manual

Put the filenames in one array and the modified dates and times in a second array. Sort the modified times using asort: PHP: asort - Manual which keeps the indexes in the original order (or use arsort if you want them in reverse order). Then step through the sorted modified times array, pulling out the keys and use the keys to access the filenames array. The filenames will then be accessed in DTM order.

[jScott_Harris]

it looks like you're already getting all the messages in an array, just reverse the array: PHP: array_reverse - Manual

you could have something in the php code like this:

if(isset($rev)):
$myarray=array_reverse($myarray);
endif;

and if $rev isn't set, it would display as it does now, but once its set, the array will come up in reverse.

Hello J. Scott Harris,

Thank you for your help. I am not a programmer. So, could you tell me how to change and add this code to my page? Where to put this code? Thanks.

Here is part of my page code:

if(!isset($page)){
$page=1;
}
$wishnum=count($temparray);
$start=$show_num*($page-1);
?>
