Checkboxes and arrays

[tail]

I'm working on a script to add users to a database. To set their permissions, I'm using checkboxes named news[], users[], etc. In my database, the permissions are set up as follows: "view,add,edit,delete". For example, in the news field, if a user can only view, add, and delete news, it would look like this: "1,1,0,1".

 

I'm using implode() to put the values into a string. However, if a box is not checked, it simply won't show up in the string instead of putting a "0" in it's spot. For example if I check view,edit,delete, the string will come up as "1,1,1" instead of the desired "1,0,1,1". My question is, how can I format the string to reflect the unchecked boxes? Thanks in advance for any help you may be able to give me!

you should have specific values for specific actions so say 1 for edit, 2 for delete, 3 view just as an example then you will be able to identify what was checked.

OK so now I'm using in_array to see if the values exist in the array like this:

$news = $_POST['news'];
if (in_array(1,$news)) {
$perms = '1,';
} else {
$perms = '0,';
} if (in_array(2,$news)) {
$perms = $perms.'1,';
} else {
$perms = $perms.'0,';
} if (in_array(3,$news)) {
$perms = $perms.'1,';
} else {
$perms = $perms.'0,';
} if (in_array(4,$news)) {
$perms = $perms.'1';
} else {
$perms = $perms.'0';
}

 

But I feel there should be a more efficient way to do this (there are 8 different permission settings). Is there?

try this a bit long way around can be shortened but works with 4 permission sets

 

<?php
// view = 1,add = 2,edit = 3,delete = 4

$_POST['news'] = array(1,3,4); // comes in from post
echo getInsertString($_POST['news']);
function getInsertString($arr) {
$array = array_diff(array(1,2,3,4), $arr);
$array = array_fill_keys($array, 0);
$array_post = array_fill_keys($arr, 1);

$array_result = $array + $array_post;
ksort($array_result);

return implode(',', $array_result);
}



?> 

 

hope its helpful

Wow that worked perfectly! I've shortened it up and will implement it in my script soon. Thank you very much for the quick responses and great deal of help.
