I have a form with a multi field that determines the price. The choice is based on age of the signed in user and the current date. I want the php code to select the appropriate price. Having selected the choice, I want to make the proper choice be checked and only it is available to the user. In my code shown below, I continually get the message
Cannot use object of type stdClass as array. It is distinctly from this line of code :
foreach ($form as $option) {
$optionArray = (array) $option; }
var_dump tells me $form is a stdClass - How can I loop through the options within the multi_field [pass_type] to pre-select the one I want.? I have 2 versions of the code - both give the error on the initial foreach.
code1:
foreach ($form as $option) {
$optionArray = (array) $option;

if (isset($optionArray) && trim($optionArray) === $choice) {
$optionArray = 1;
echo 'we found ' . $optionArray('text');
$filtered[] = $optionArray;
$matched = true;
break;
}
}
code2:
foreach ($form as $option) {
if ($option->text === $desiredLabel ) {
$form = [
'0' => [
'value' => $option,
'text' => $option,
'amount' => $option,
'tax' => $option,
'checked' => 1
]
];
break;
}
}
I would really appreciate any help or suggestions. Although I have an account with rsJoomla they seem to feel this is custom code!

Use JavaScript, I have a membership form where we have rates for UK, Europe , and Rest of the world. With Javascript you can use the country the user has enterd to 'grey out' the UK and Europe member rates leaving the correct optons available. That seems similar to what you are trying to achieve. You can see it in action at this site, just change the country and watch the membership rates
