Question

I have a function that takes in 2 params ($group, $array)

$group = the ‘name’ of the input attribute
$array = the array of checkbox values

function checkboxes($group, $array) {
    $string = NULL;
    $group = (string)$group."[]";
    foreach($array as $key => $value) {
        $string .= "<br /><input type='checkbox' id=".$value." name='".$group."'        value='".$value."' /><label for=".$value.">$value</label>";
    }
    return $string;
}

What I’m trying to do is convert that into proper HTML, so that I can process the value in a script.

here is the input:

checkboxes("class", array("Warrior","Mage","Priest","Rogue"));


$boxes = $_POST['class'];
for ($i=0; $i<count($boxes); $i++) {
    echo $boxes[$i];
}

Output: “R” (when more than one are checked as well)

Any help would be great, sorry if I forgot anything.

This is homework, so don’t give me answers that break the stackoverflow terms/my schools honor code please!

Answer 1

Try this. It seems to print all checked boxes.

<?php
function checkboxes($group, $array) {
    $string = NULL;
    $group = (string)$group."[]";
    foreach($array as $key => $value) {
        $string .= "<br /><input type='checkbox' id=".$value." name='".$group."'        value='".$value."' /><label for=".$value.">$value</label>";
    }
    return $string;
}

if( isset( $_POST[ 'class' ] ) ) {
    $boxes = $_POST['class'];
    for ($i=0; $i<count($boxes); $i++) {
        echo $boxes[$i] . '<br />';
    }

}
?>
<form action="t23.php" method="POST">
    <?php
    echo checkboxes("class", array("Warrior","Mage","Priest","Rogue"));
    ?>
    <input type="submit"  name="btnOutput" value="submit"/>
</form>
