Question

My problem is a little bit complicate. (I use PHP)

I have two arrays, (simple arrays array[0] = string, array[1] = string…) OK, now I will display the content of two arrays in a webpage. The first array contain names and the second images URL.

Images and names are already displayed (my problem isn’t here).

But now I want to do something else, add a check box near every image, those checkbox r active by default. Ok, now the user can uncheck some inbox;

The final aim, is to get a new array containing only the values of the names and images that had been checked.

I have thought of something simple, crawl the keys (number) of unchecked checkboxes and unset them from my array. But the problem that I didn’t know how to deal with the check boxes

Answer 1

first of all i recomend having just one array:

$array = array (0 => array('name' => '....', 'url' => '....')) 

i think this will make your life much easier. Also in the HTML you could also send the array key

foreach ($yourArray as $key=>$value) {     ...     <INPUT type='checkbox' name='chkArr[<?php echo $key ?>]' value='1' checked/>           

then in your form action you itarate the intial array and remove the unchecked ones.

foreach ($yourArray as $key=>$value) {        if (!isset($_POST['chkArr'][$key]) OR $_POST['chkArr'][$key]!='1') {         unset($yourArray[$key]);       } }
