Comparing Two Arrays

[Anon]

I have 3 columns for a HTML table. Each row represents an individual data entry and the first two columns are labeled "accept" and "reject" while the third column shows a description of the row.

What I've done is have checkboxes that goes down the first and second column. The user has the option to select all (reject or approve). The problem that I have now is that the user will more than likely select both "reject" and "approve" checkboxes for a particular row which could wreck things.

I couldn't find a PHP function that will compare for duplicates within two arrays because that is how my script is handling "accept" and "rejects". Each "accept" entry is part of the accept array and all the "reject" entries are part of the reject array.

The script will then go through the accept array and validate them then run through the reject. So if a user selects both the accept and reject checkboxes, I will have duplicates and really don't want to code a function to go through the array and perform a comparison if a PHP function exists since it might take a while if the array of rejects and accepts are large for a comparison.

Any suggestions?

Why not use radio buttons instead of checkboxes?

Well, I also need to supply a checkbox that will perform a "select all" on the form depending on the operation they choose.

Let's say I got 10 rows of data that can either be selected reject or accept.

If I use radio buttons, I wasn't able to find any JS code which can select all accept radio buttons if the user was to check off the "select all accept" button.

The JS code I'm using will check off an entire group of checkboxes, but if I'm using radio buttons, there will be 10 different groups of radio buttons. I'm not sure I'm explaining my delima very well, but hopefully you can understand it. 🙂

Actually, you know what. I found this function array_diff()

$array1 = array ("a" => "green", "red", "blue", "red");
$array2 = array ("b" => "green", "yellow", "red");
$result = array_diff ($array1, $array2);

What I could do is compare the accept and reject arrays and get the differ array. Then I can run a test on whether the count of $array1 plus the count of $array2 is equal to the count of $result. Let me go and try that out now. . 🙂
