选择值数组

Question

So basically, I have an array of Modules and I want to have a drop-down menue that users can then select what grade they got. This works fine, however, I would like the results to be stored inside of an array, to however many values they selected. So for example:

If someone selected "40" in Mod1 and in Mod2 they selected "20" then the array would be like this:

mod1=>40

mod2=>20

...

Here is the code so far, it's probably something stupid, I just cannot get my head around it.

<?php

$modules = array('Mod1', 'Mod2', 'Mod3');   

if(!isset($_POST['submitted']))
{
    echo '<form method="post">';

    echo 'Please enter the grades you got for each Module: <br />';
    foreach($modules as $module)
    {
        echo $module . ': <input type="text" name="grades[]" value=""> <br />';
    }
    echo '<br /><input type="submit" name="submit" value="Go!">';
    echo '<input type="hidden" name="submitted" value="TRUE">';

}else{

    $input = $_POST['score[]'];
    foreach($modules as $i => $module){
        $input[$module] = $input[$i];
        var_dump($input[$module] = $i);
        //unset($input[$i]);
    }
    //var_dump($input);

}

?>

Answer 1

<select name="score[<?php echo $module; ?>]">

should get you going :)
the array will look exactly like you narrowed it down in the intro.

Answer 2

just change your name attribute to an array:

echo '<select name="score[]">';

the the $_POST variable will be in an array

Answer 3

You could use a name that groups the values of the select s in POST into one array:

echo '<select name="score[]">';

You can then use:

$input = $_POST['score[]'];
foreach($modules as $i=>$module){
    $input[$module] = $input[$i];
    unset($input[$i]);
}
var_dump($input);
