I have never used enum type but I am sure it is not what you want as
it will only store one item from a predefined list not a list of
items. What you need to do is create an array of the selected items,
serialize() it to store in the database in a varchar or mediumtext if
it going to get big. Then when you read it back unserialize and loop
through all the options setting checked if it is in the array.
To keep the checkboxes grouped name them like this:
input type=checkbox name=school[1]
input type=checkbox name=school[2]
input type=checkbox name=school[3]
That will show up as an array under $_POST['school']
so you can serialize it as is and store it.
?
if(isset($_POST['school'])) $school = serialize($_POST['school']);
?
Playback is simple too
?
$school = unserialize($row['school']);
for($i = 1;$i 41;$i++){
echo 'input type=checkbox name=school['.$i.']';
if(isset($school[$i])) echo ' checked';
echo '';
}
Un-checked boxes are not returned in the post and checked ones
return Yes I think.

Re: [PHP] Enum table entry
You know, I didn't even think about serializing the array. I have a
table set up for spells, one for schools, and a linking table using the
spell id and the school id(s). I could have done without the linking
table. Some of you people are pretty freakin' smart. :)
One note though, when you pull the serialized data out, you may have to
stripslashes before unserialize...
$school = unserialize ( stripslashes ( $row['school'] ) );

As the only thing going in is 1-yes add and strip isn't needed. You
should never need to stripslashes on db output under normal
conditions. If the data could contain single quotes and stuff then you would do it like
this
addslashes(serialize($_POST['school']));

Assuming your field is:
school enum( 'abjuration', 'conjuration', 'divination', ... ),
The database will return, 'abjuration,divination' in the example listed
above, and it will expect the same kind of string when setting the field
in an UPDATE or INSERT query.
(or however enum data is input into its column). That being the case how
do i utilize php to get this to work? what kind of form elements etc...
The problem im seeing with checkboxes are that they are discreet and dont

Hopefully i havent horribly confused the issue and some kind soul out
there can tell me how to send this data across. As a double nice
thing...how would you write it to pull the data back out...ie, convert 1,
3 to show abjuration, divination? Thanks for the help in advance.
To get the data in/out of the database you can do something like this:
Start with an array of possible choices, because you are going to
have to act on each possible choice.
$SchoolChoices = array( 'Abjuration', 'Conjuration', 'Divination', ... );
To setup the variables from the table for display. Note the value
from the database is in the string $School.
reset( $SchoolChoices );
while( list( , $Choice ) = each( $SchoolChoices )) {
$VarName = 'School' . $Choice;
$$VarName = ereg( $Choice, $School ) ? 'CHECKED' : '';
}
Now you can send the form displayed below with the values from
the database.
FORM Method=GET ...
INPUT Type=checkbox Name=SchoolAbjuration Value=?=$SchoolAbjuration?
INPUT Type=checkbox Name=SchoolConjuration Value=?=$SchoolConjuration?
INPUT Type=checkbox Name=SchoolDivination Value=?=$SchoolDivination?
...
/FORM
===
After the user enters the form, you can decode the fields and put the
data into a string for storage in the database with:
reset( $SchoolChoices );
$School = '';
while( list( , $Choice ) = each( $SchoolChoices )) {
if( 'on' == $_get( School$Choice )) {
$School .= ',' . $Choice;
}
}
$School = substr( $School, 1 );
Now you can INSERT/UPDATE the database with $School to set the enum field.
You can create the checkbox fields from $SchoolChoices with the following:
reset( $SchoolChoices );
while( list( , $Choice ) = each( $SchoolChoices )) {
$VarName = 'School' . $Choice;
echo INPUT Type=\checkbox\ Name=\$VarName\ Value=\$$VarName\;
}
For extra credit, figure out how you can create the $SchoolChoices array
from the output of the following query:
DESCRIBE TableName School;
(Yes you can send this to mysql_query, and get the possible values of the
enum.)

RE: [PHP] Enum table entry
There should really be another table for all of this information. Say you're tracking school information for a specific person. That person would have an ID number and you'd store the school information in a separate table that stores the user's ID and the school ID. You could even expand this to track other items by adding a third column that says the item being tracked is a school, spell, item, etc. This may seem like a pain now, but it's going to be the most scalable solution. Using serialize, what happens when someone has all 40 schools and it's over 255 characters? Do you make them all text columns? An ideal solution would involve a variety of tables. Table 1: Users. This would store user information such as name, rank, etc, and assign each one a unique ID. Table 2: Schools. This would list all of the possible schools that someone can take and assign each one a unique ID. Table 3: Spells. This would list all of the possible spells and assign each one a unique ID. Table 4: Call it what you want but this table is going to link the user IDs to school and magic IDs. If a user (User_ID=1) has schools abjuration (ID=2) and conjuration (ID=5), then you'd have two rows in this linking table, 1-2 and 1-5. Okay... I've blabbered enough. ---John Holmes... -Original Message- From: Shiloh Madsen [mailto:shiloh_madsen;nsc-support.com] Sent: Saturday, October 19, 2002 12:48 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: [PHP] Enum table entry Have a question that im trying to figure out how to resolve.
