$reg_csv_array is an associative array, using array_push() will add the element using the last index, so it will add [0] => 'myConstantValue' to the array, which is why you see ‘0’ in the column header.

Use $reg_csv_array[$key] => $value; to add to the array.

So in the example you gave, you would have:

$reg_csv_array['MyConstant'] => 'myConstantValue';
return $reg_csv_array;

Sorry, I assumed based on your opening thread you were comfortable with PHP.

The reason my example crashes the site is because I made a schoolboy error.

Remove the > so its:

$reg_csv_array['MyConstant'] = 'myConstantValue';

Now, I’m wanting to do something in reverse. My assumption is that the second parameter is also an associative array. So, why would this code cause a crash?

Because that assumption is incorrect 🙂

I’m not sure what made you come to that conclusion, but $reg_csv_array is an associative array where each key is a string and each value is a single value.

For example, when we did this:

$reg_csv_array['MyConstant'] = 'myConstantValue';

We add an element to the array with a key ‘MyConstant’ and a value ‘myConstantValue’. That’s included directly in the CSV and as it’s a string (integers and floats also work) it worked correctly. So if you wanted the user ID to be included in the CSV, the value you add to the array is 6404, not array/object containing that value.

We actually have methods within EE that help you do all of this much easier:

//Any fields you add to the CSV must be added to all, if even if the value is empty, so initialize the 'User ID' key:
$reg_csv_array['User ID'] = ''; 

//Do we have a wp_user for this attendee record?
$user_id = EE_WPUsers::get_attendee_user($reg_row['Registration.ATT_ID']);
        
if (!empty($user_id)) {
    //You have a user id saved to $user_id.
    $reg_csv_array['User ID'] = $user_id;  
}

EE_WPUsers::get_attendee_user({ATT_ID}) pulls a user id for the contact’s ATT_ID you pass to it, it returns the user id as an int (whole number) if there is one, or null if not. So we check if user_id is not empty, and if not, add it to the array.

As you have the $user_id in the variable, I’m assuming from your first question your going to pull details fro user meta, again you need to add each value to the array individually as key => value so you’ll need to check which data types you have first.

Not currently, you would need to look through the code itself.

Hi,

WordPress actually has a function you can use to get a specific user meta field. You’ll find some examples of how to use the function in its documentation:

Although data from wp_usermeta is from field meta_value which is only one data type.

This isn’t actually true, get_user_meta() will return either a string or array, with your setup it’s a string.

However, when plugins add fields types such as checkboxes to user meta, they’ll store the values in a serialized array, which when returned, it still a string.

Try something like this:

$value = maybe_unserialize(get_user_meta($user_id, $key, true));
if( is_array($value) ) {
    $value = implode(', ', $value);
}
$reg_csv_array[$key] = $value;

Pull the value, unserialize if needed (it will just be returned to $value if not needed), if it’s an array piece them together and return as a string, then set the value.

I installed Ultimate member to test this and got the same issue with both registrants, I’m not sure why your only getting it on the second. Does the first definitely have those checkboxes checked in their profile?

Glad to hear. If you have a moment, perhaps you can share a brief note about your support experience here:
