Re: [PHP-DB] Re: Formatting
Ethan,
is this valid PHP? What is the ampersand for? What is it doing? Just
curious.
$args[] = $_POST[$k]; // Note the addition of the ampersand here

FYI, this really is not the appropriate mailing list for these types

Are you positive they are empty lines? i.e., are they in the html
code of the page, or only appear as empty space in the rendered page?
If they are just in the rendered page, in addition to losing the /
div in the middle of your table (as someone has suggested), you
might also want to check your stylesheets. In particular, this looks
like it could cause some strange things to happen depending on what
you're doing with it:
td class=first-col
Try loading up firebug and looking at the table element and the
elements around it to see if there is some strange padding. Or, try
disabling any stylesheets you are loading with the page to see if it
still renders in an undesirable way.
Good luck,
-Matt

Did not notice; was not looking for them. Of course if you knew about
html tables you would know not to put them in there. A little knowledge
seems to be the root of all your bugs once again.
You really should read up on HEREDOCS in the php manual. It will save
you mucho amounts of typing and confusion when mixing php and html code.
Ex.
$code =heredocs
tr
td$vara2[$i][0]/td
td$vara2[$i][1]/td
td$vara2[$i][2]/td
td$vara2[$i][3]/td
td$vara2[$i][4]/td
td$vara2[$i][5]/td
td$vara2[$i][6]/td
td class=first-col$vara2[$i][7]/td
td$vara2[$i][8]/td
td$vara2[$i][9]/td
/tr
heredocs;
echo $code;
This does all that you code does with much less chafe in the code.

[PHP-DB] CSV storage InnoDB?
Hello all, Quick question. What is the best way to store a comma separated list of discount codes in a InnoDB? Text, varchar, blob, ? I want to be able to store discount codes offered to users in their profile, in their cart, etc. So I am thinking of storing the codes as a comma separated list that I can then refer to, add to or remove codes from. The codes will change every once and a while and they list of codes may be rather large after say a year, so I am shying away from an enum() or anything like that. Any help/pointers is greatly appreciated. Best, Karl -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] CSV storage InnoDB?
Karl, Typically I would do this as multiple rows rather than comma-separated data in one field. If you go this route, you may consider adding an unsigned int primary key (with auto increment) on the discounts table so you consume less storage space and can do joins more quickly. `discounts`: id discount_code product_id_or_whatever 1sfeijfkjx 34 2kbgrlijf 36 `user_discounts`: user_id discount_id 1231 1232 4563 If you really needed to SELECT the data with comma separation, you could use something like GROUP_CONCAT (http://dev.mysql.com/doc/refman/5.0/en/group-by-functions.html#function_group-concat), but I would try to avoid that. This is a very basic design principle for relational databases. You may want to do some more reading about database architecture in general. That said, you could use a TEXT field to store a comma separated list, I just wouldn't recommend doing it that way. -Matt On 11/26/2012 06:01 PM, Karl DeSaulniers wrote: On Nov 26, 2012, at 7:29 PM, Bastien wrote: Bastien Koert On 2012-11-26, at 7:43 PM, Karl DeSaulniers k...@designdrumm.com wrote: Hello all, Quick question.

BLOB and TEXT are basically the same thing, except that BLOB can be used
for storing binary data (like an image).
You would only need one additional table to do what I was describing,
but if you're dead-set on using a comma separated list then TEXT or
LONGTEXT is probably what you want, depending on how large you
anticipate those lists becoming.
