editing my database

rakennedy75

i have features stored in my db and I want to let the user edit them but i am having a problem displaying them correctly. These features are items such as:
fax, cable, tv, vcr, dvd, etc....

I am able to allow the user to add them using checkboxes and to keep the db consistent I want them to use the checkboxes to edit them as well. So when I display current features I would like the ones that are already selected to be checked and the ones that are not selected to be unchecked. I have an array that is hard coded with all the available features. The info is pulled out of the db and put into an array and I want these checked against the hardcoded array.

a basic example would be:
$hardcoded = Array("fax, "cable", "tv", "vcr", "dvd");
$infoFromDb = Array("fax", "tv", "dvd");

so all of the $hardcoded would be listed with checkbox and the only ones that would be checked would be the ones in the $infoFromDb array. So each element of the $infoFromDb array needs to be checked against each element of the $hardcoded array and listed as i have stated above. I don't exactly know how to go about this. I am assuming I will have to use multi-dimensional arrays but I have no idea where to start with this. Any help would be appreciated. Thanks for your time.

take a look at

array_diff() returns an array containing all the values of array1 that are not present in any of the other arguments. Note that keys are preserved. array_diff

i think thats what you are looking for?

For simplcity, does each user have its own table ie account? The reason why I ask is because it would be easier for you to input the values of hardcoded into each database. In other words, if the user opens his account for the 1st time, the variables of hardcoded should be included int the database 1st. However, if the user decided not to have some items included is not selected. Simply, let them UPDATE. After the update create a loop or soemthing that retrieves the values from the database such as fax tv ect, and let those be unchecked. All and all, there is HTML and PHP involved.

$hardcoded = Array("fax, "cable", "tv", "vcr", "dvd");
$infoFromDb = Array("fax", "tv", "dvd");

Thanks for the replies, I think the array_diff will work. The only other question, is there a way to remove the keys or at least omit them for displaying purposes.

Thanks for your time guys.
