Re: [PHP] php, mysql, and method question
Charles, it sounds like you want the most recent 9 articles ("...order set
to 1 so it shows up first when ..."), so why not something like "select *
from article_table order by id desc, limit 9" [assumes id is int not null
auto_incremented].
You could also increment the value in the field something like:
$result=mysql_query("select article_order from article table");
while ($array_result=mysql_fetch($result))
{
$article_order=$array_result[article_order]+1;
mysql_query("update article_table set article_order=$article_order where
id=$array_result[id] ");
}

[PHP] php, mysql, and method question
hi all, i have a question about a good method of handling this challenge. i have a table that contains articles. i have another table which contains the order 1 - 9 that i would like to display them in. this part is done, and is not a problem. here is where I am not sure how to proceed. 1. tbl_display_order - can only have 9 records in it (or do i just ignore anything beyond 9?) 2. when a new article is added to tbl_display_order - it needs to get the field that contains it's order set to 1 so it shows up first when I display the articles, and all the other articles need to have their order number incremented. Maybe there is a better way to do this? Just not sure. Maybe not with a database at all? Thanks for suggestions.
