There is an array of user states stored in the session. This works:
<?php if ($_SESSION['_app_user']['data']['state']['1']) { ?>
<p>User has state 1</p>
<?php } ?>
But, selecting multiple states doesn't:
<?php if ($_SESSION['_app_user']['data']['state']['1,6,10']) { ?>
<p>User has state 1 or 6 or 10</p>
<?php } ?>
How can you check on multiple states?
By checking multiple.
You may find it easier to store the least common denominator to a temporary variable:
$s = $_SESSION['_app_user']['data']['state'];
if(isset($s[1]) || isset($s[6]) || isset($s[10])) {
echo 'Tahdah!';
}
unset($s);
Also, please use quotes for your strings. It makes code clearer, and saves the PHP interpreter a bit of effort guessing that you mean a string instead of, say, a constant named _app_user :)
May be it's better to use "array_key_exists" function to check if the given index exists in the array. See Example #2 array_key_exists() vs isset(). https://www.php.net/manual/en/function.array-key-exists.php
array_key_exists with the example I posted? Or are you saying I should use Matchu's solution with array_key_exists instead of isset?
You could also use array_intersect to check an array of states against your user states. For example:
$user_states = $_SESSION['_app_user']['data']['state'];
$check_states = array( 1, 6, 10 );
$matches = array_intersect(array_keys($user_states), $check_states);
if(!empty($matches))
{
echo "User has valid states: \n";
foreach($matches as $_state)
{
echo " - {$_state}\n";
}
}
else
{
echo "Sorry. Not found.";
}
The function checks whether any two elements in the arrays match, and returns all the matches. Meaning that in that code, the $matches array would be a list of all the states that the user has and are in your list.
