| I'm using a modified version of Weasel's item shop on my board, and I want to do another modification to it. The modification would be tedious to do, so I'm hoping there's some way to make it fast/automated. What I want to do is add an ID to all the items for sale. The only way I can think of to do it is to manually add the field to each table, and then manually assign an ID to each item, one at a time. Is there some php script thingy I can use that will add the ID field, and add a number to it at the same time? Or will I have to do it "by hand"? |

| *wonders why the feck you want to work with a field per every item instead of an organised table* | |||

Adding a field for every item still is a bad idea.  Either way, you add a field with the following query, I'll let you use it anyway until you find out why adding a field for every item is bad. Adding a 'fieldname' field with varchar(15) type: ALTER TABLE 'tablename' ADD 'fieldname' VARCHAR(15) NOT NULL; Adding a 'fieldname' field with int(5) type: ALTER TABLE 'tablename' ADD 'fieldname' INT(5) NOT NULL; |

| I don't think you understand what I'm trying to say. Sorry about that. Let me give you an example: I have my MySQL database, and we'll call it fakedb. Then, I have a table called armor_shop. When I'm looking at it in phpMyAdmin, the top of the page says this: Database fakedb - Table armor_shop running on fakehost Next, I have the following fields: Field Type Null name varchar(255) no price int(11) no def int(3) no spd int(3) no hp int(3) no legend int(3) no Now I want to add a new field, called id, and I want to to enter a value for each item, so that I don't have to click on armor 1, enter the value, click save, click on item 2, enter the value, click save, etc. |

| That's just a matter of running update queries in a PHP script, an example (this script assumes the new 'id' field is already there): $item_q=mysql_query("select name from armor_shop order by name"); $new_id=1; while($item=mysql_fetch_array($item_q)){ mysql_query("update armor_shop set id=$new_id where name='".$item[name]."'"); $new_id++; } echo "Done"; This script selects all records from the database, and assigns an ID to every row. |

You probably understood it becuase you're as mentally screwed up as I am.  As for not reading it until now, well, better late than never. |
