Question

I’ll try and be brief but concise.

I have a PHP form page that populates a drop-down box with data (magazine names) from an array, and then, if posted, outputs it to another page.

However, I have a second array within the form (containing subscription links), that I also need to send to the output page, depending on what was chosen from the drop-down box. If that makes sense.

For example, if the value for for $arrayOne[7] is chosen from the drop-down box, I need to post_GET the value for $arrayTwo[7] over to the output page automatically, as well.

Can anyone help?

default.php:

$arrayOne[0] = "magazineA";
$arrayOne[1] = "magazineB";
etc...

$arrayTwo[0] = "subscriptionLinkA";
$arrayTwo[1] = "subscriptionLinkB";
etc...

<form action="index2.php" method="get">
<?php

echo '<select name="publication">';
foreach ($magazine as $publication)
{
    echo '<option name="publication" value="' . $publication . '">' . $publication . '</option>';
}
echo '</select>';

?>
<input type="submit">
</form>

index2.php:

<p>
If you have subscribed to <?php echo $_GET["publication"]; ?>,
you will receive your hard-copy in due course. If you are not a current subscriber,
<a href="#">click here</a> to subscribe.

Answer 1

Since the value from $array2 is completely dependant on the value of $array1, $_GET['a1'] can act as a lookup for the other value. ie you don’t have to pass $a2 at all.

On index2.php, you’d have something like this:

$arr2= array( 'magazineA' => 'subscriptionLinkA',
              'magazineB' => 'subscriptionLinkB');

$pub= $_GET['a1']; //you'd want to sanitize this value of course
$link= $arr2[$pub];

echo  <<< EOT
<p>
If you have subscribed to $pub
you will receive your hard-copy in due course. If you are not a current subscriber,
<a href="$link">click here</a> to subscribe.
</p>
EOT;
