Issue with SugarSmarty unknown modifier sugar_escape

Kim Nguyen

Hi,

Has anyone experience issue with not being abled to create a customised field in Sugar?

Sugar log displays issue as:

Wed Jan 14 15:17:44 2026 [25][1][FATAL] Exception in Controller:  --> Smarty Compiler: Syntax error in template "file:/var/www/html/sugar/modules/DynamicFields/templates/Fields/Forms/varchar.tpl"  on line 20 "<input type="text" name="default" id="default" value="{$vardef.default|sugar_escape:'html':'UTF-8'}"" unknown modifier 'sugar_escape' <--

When I checked the folder Include/SugarSmarty, there was not any file with name modifier.sugar_escape.php. I added the file in manually but still the issue persist and Sugar log shows as the above.

Sugar version: 25.2.0

Pls reach out if you have any idea.

Thank you

Vy

    I am on 25.1.0 and do have a file 

    include/SugarSmarty/plugins/modifier.sugar_escape.php

    I don't know if it was removed in 25.2.0 (we are on-site and that release is not for on-site customers).

    FWIW This is what it looks like in 25.1

function smarty_modifier_sugar_escape($string, $esc_type = 'html', $char_set = null, $double_encode = true)
{
    do {
        $oldData = $string;
        $string = htmlspecialchars_decode($string, ENT_QUOTES);
    } while ($string !== $oldData);
    require_once 'vendor/smarty/smarty/libs/plugins/modifier.escape.php';
    return smarty_modifier_escape($string, $esc_type, $char_set, $double_encode);
}

    Hope this helps you,
