Hi all, i want to validate form text field that is generated by CHtml::textfield that does not have any model.

<?php echo CHtml::textField(‘page_size’, ‘25’, array(‘size’=>3,‘maxlength’=>3,‘value’=>25)); ?>

It should accept only integer fields.How can i do this?

Either you can use jquery validation plugin.

use client side validators

  1. If you do need to validate the user input, for example before you store the value to database, then using a model is the right choice. It will make things quite easy for you.

Remember the client side validation is not enough. We have to validate it in the server side.

Consider using CFormModel if ‘page_size’ is not an attribute of some CActiveRecord.

  1. If you are working with the page size of a CGridView or CListView, then you can simplify the validation by using intval(), without using a model.



$pageSize = isset($_GET['page_size']) ? intval($_GET['page_size']) : $defaultPageSize;

if ($pageSize <= 0) {

    $pageSize = $defaultPageSize;

}

By forcing the conversion to an integer, you’ll be free from the danger of a malicious input.
