XF 2.0 ACP : user search criteria - strange exception

[Jean-Baptiste]

Hello,

I would like to add a custom search user criteria.

I added the following code in the helper_user_search_criteria template :

    <xf:formrow rowtype="input"
    label="{{  phrase('referal_date')  }}">

    <div class="inputGroup">
        <xf:dateinput name="criteria[referal_date][start]" value="{$criteria.referal_date.start}" size="15" readonly="{$readOnly}" />
        <span class="inputGroup-text">-</span>
        <xf:dateinput name="criteria[referal_date][end]" value="{$criteria.referal_date.end}" size="15" readonly="{$readOnly}" />
    </div>
       
    </xf:formrow>

And the following user_criteria listener :

        switch ($rule)
        {
            case 'have_used_mobile_app':
                if ($user['referal_date'] > 1)
                {
                    $returnValue = $user['referal_date'];
                }
                break;
        }

But it's not working, I got the following exception when I hit the search button in my ACP :
