[Resolved] Cannot create required field

I am trying to:
I created some "Add Custom Post Forms" with these options >> Are you interested to: 1) BUY / 2) SELL. I need the customer to be forced to click on one of them (buy or sell, not both - just one) and I don't know how to make the selection required.

From your support forum I tried this function:

function my_validation($field_data, $form_data)
{
//field data are field values and errors
list($fields,$errors)=$field_data;

//uncomment this if you want to print the field values
//print_r($fields);

//validate if specific form
if ($form_data['id']==25559)
{

//check if field is selected
if (empty($fields['wpcf-type_of_proposal']['value']))
{
//set error message for featured image
$errors['wpcf-type_of_proposal'] = 'Please Specify if you are looking to Buy or Sell';
}
}

//return result
return array($fields,$errors);
}

This works only with one form. When I try to create a similar function for other forms (with other ID's) it does not work.

Link to a page with the form:
hidden link

Please advice.
Thank you!

Hi Valentine,

Thank you for contacting our support forum.
Could you let me know which field on this form here below you are trying to make required ?
hidden link

Thanks,

I need the user to check only one of those two fields (image attached), I need the selection to be required.
For you to see that page you must create a free account.

Hi Valentine,

I'm actually not seeing the exact same thing as you have in your screenshot.

Perhaps I need to be logged in?

If so i've enabled the private fields for your next response.

Thanks,
Shane

Yes , you need to create a free account (from that page that you see) and then you need to login.

Hi Valentine,

Based on what I see here your form ID is incorrect in the Hook.

It should be 25621

Thanks,
Shane

That is what I'm telling you. I created that function and it only works with one form (the form with the ID 25621). How can I make that function to work on multiple forms?

Hi Valentine,

Thank you for the clarity. This is actually quite a simple fix.

Change this here

//validate if specific form
if ($form_data['id']==25559)
{

To

$form_ids = array(1,2,3,4,5)

//validate if specific form
if (in_array($form_data['ids'],$form_ids))
{

Now you just need to put your ids in the id array separated by commas.

Please let me know if this helps.
Thanks,
Shane

It still does not work.

Hi Valentine,

Could you paste to me exactly what you have now ?

Try this

$form_ids = array(1,2,3,4,5)
 
//validate if specific form
if (in_array($form_data['id'],$form_ids))
{

I made a simple error in the ID call for the form.

Thanks,
Shane

When I try to save the functions file I get this message:
"
Changes you made to the PHP code have been canceled due to an error on line 227 of the wp-content / themes / kleo-child / functions.php file. Please correct and try saving again.

syntax error, unexpected 'if' (T_IF)

"

This is what I have now:

function my_validation($field_data, $form_data)
{
//field data are field values and errors
list($fields,$errors)=$field_data;

//uncomment this if you want to print the field values
//print_r($fields);

$form_ids = array(25559,25621,25640)

//validate if specific form
if (in_array($form_data['id'],$form_ids))
{

//check if field is selected
if (empty($fields['wpcf-type_of_proposal']['value']))
{
//set error message for featured image
$errors['wpcf-type_of_proposal'] = 'Please Specify if you are looking to Buy or Sell';
}
}

//return result
return array($fields,$errors);
}

Hi Valentine,

There was a missing semi-colon

$form_ids = array(25559,25621,25640);

That should work now

[valentinP-3]

It still does not work. 🙁

Hi Valentin,

That is odd as it should now work.

Would you mind allowing me to have admin access to the site so I can see what is happening here?

Thanks,
Shane

Hi Valentine,

I believe i know what the issue is.

The field you are trying to validate, it's a custom taxonomy and not a custom field.

We actually don't have a way to set the taxonomy as required through our api. What you can do is to use JS to set the field as required.

Take a look at this here.

This should be able to help you with this issue.
