Why Submit Is Automatic ?

[Skayfer]

Hi,

 

I am working with my simple module and i have next problem, that i can't understand.

 

In module config page i have to forms. First display something from db in inputs and works great. When i change something in input and not click save (submit this form), change wouldn't be save in db, when i click save all inputs are update, great. But in second form, that i use to add new rows in db is problem.

 

When i am in new tab in this config page and realod my page nothing happens. But when i only once type something to inputs second form, click this submit, it looks like vars are not cleared. Now if i reload page 10 times i will have 10 new field, although i don't click submit.

 

code from get Content function:

 

$new_field_title = null;
            $new_field_value = null;


            if (Tools::isSubmit('add_new_field')){
                $new_field_title = strval(Tools::getValue('new-field-title'));
                $new_field_value = strval(Tools::getValue('new-field-value'));
                
                if( !$new_field_value
                    || empty($new_field_value)
                    || !Validate::isGenericName($new_field_value)
                    ||!$new_field_title
                    || empty($new_field_title)
                    || !Validate::isGenericName($new_field_title) ){
                }
                else{
                    $sql = "INSERT INTO "._DB_PREFIX_."fields (title, value) VALUES ('".$new_field_title."','".$new_field_value."')";        
                    Db::getInstance()->Execute($sql);    
                }
            }
