Live Number Inputs

When using live inputs we need to have the following option types on our section: L ,

When using number fields it is important to set inputType as "number" and add a few attributes, like step and min. Step allows decimals, in the following example 2 decimals, one decimal at a time. 

For Decimals

addField([
   'type'=>'live',  //required
   'inputType' =>'number', //required
   'label'=>'Amount', //required
   'name' => 'cost', //required (column name)
   'attributes'=> 'min="0" step=".01"', //this allows 2 decimals (9.99)
   'value' => '' //optional, it can be left empty or add the value from the database
   'ID'=>'amount_to_pay', //optional, name is used by default
   'encdata'=>[  //optional unless $dbtable, $idfield and $idvalue are not declared, 
      'TYPE'    =>'LIVE',
      'DBTABLE' =>$dbtable,
      'IDFIELD' =>$idfield,
      'IDVALUE' =>$idvalue
   ],
   callback => 'location.reload()' //optional
]);

For Integers:
If we only want to allow integers step should be equal to 1 and to prevent decimals add the following JS to the attributes: onkeypress="return event.charCode >= 48 && event.charCode <= 57"

addField([
   'type'=>'live',  //required
   'inputType' =>'number', //required
   'label'=>'Amount', //required
   'name' => 'cost', //required (column name)
   'attributes'=> 'min="0" step="1" onkeypress="return event.charCode >= 48 && event.charCode <= 57"', //this doesn't allow decimals
   'value' => '' //optional, it can be left empty or add the value from the database
   'ID'=>'amount_to_pay', //optional, name is used by default
   'encdata'=>[  //optional unless $dbtable, $idfield and $idvalue are not declared, 
      'TYPE'    =>'LIVE',
      'DBTABLE' =>$dbtable,
      'IDFIELD' =>$idfield,
      'IDVALUE' =>$idvalue
   ]
]);
