Making radio buttons sticky in a foreach array loop

[sh89]

Hello all. I have tried to figure out why I can't make a certain part of my code sticky. I am attempting to save the user's input for the radio button section. I am using a foreach loop for everything in my array. When I try to use if isset, it returns the last item in the array instead of what was selected by the user. Here is the code:

 

<?php

 

//Creating foreach loop for magazine selection

foreach ($magSubs as $mag => $SUB_PRICE)

{

    echo "<input type='radio' name='magtype' value='$mag' />$mag $$SUB_PRICE per month<br> ";

}

?>

 

Again, I want to make this part sticky.

try addiing checked="checked" to your input

I tried that, but unfortunately all that does is check the last item in the array. I also tried that with if isset, to no avail.

This is what I've come up with, but I still have the issue of it checking the last item in the array and not the button that was selected:

<?php

 

//Creating foreach loop for magazine selection

foreach ($magSubs as $mag => $SUB_PRICE)

{

    echo "<input type='radio' name='magtype' value='$mag' ";

    if (isset($_GET['magtype']))

    {

        echo "checked='checked'";

    }

    echo " >$mag $$SUB_PRICE per month<br>";

}

?>

For multiple radio buttons, the HTML name attribute needs to represent/produce an array. name="magtype[]". In your loop, you need to check for the value in the array:

 

//Creating foreach loop for magazine selection
foreach ($magSubs as $mag => $SUB_PRICE)
{
    echo "<input type='radio' name='magtype[]' value='$mag' ";
    if (isset($_GET['magtype'])) {
        if (in_array($mag, $_GET['magtype'])) {
            echo "checked='checked'";
        }
    }
    echo " >$mag $$SUB_PRICE per month<br>";
    // WHAT IS   ^^ THIS? Is that supposed to be a variable-variable?
}
