Through my research, I think the best solution if your data is in array format then try this => Stackoverflow: How to trim white spaces of array values in php

While, if your data is not an array then you can simply use:

$data = trim($data);

The best place to remove whitespace from user input i.e. trim() is in the beforeFilter() callback at the Controller level. For PHP5+ the array function array_walk_recursive() makes this job very easy.

For example:

public function beforeFilter()
{
    parent::beforeFilter();

    // remove leading and trailing whitespace from posted data
    if (!function_exists('trimItem')) {
        function trimItem(&$item,$key){
            if (is_string($item)){
                $item = trim($item);    
            }
        }
    }       
    array_walk_recursive($this->request->data, 'trimItem');                     
}

Drop this code into AppController and user input will be trimmed on all forms

Hope this helps

Just as an addition to @Prasantn Bebdra's answer and since the asker doesn't know where and how to use trim().

To trim all the data that is comming from POST in your controller (just before the call to Model->save()) do:

foreach ($this->data as $key => $value) {
    $this->data[$key] = trim($value);
}

You can also use this in the Model by utilizing one of it's callbacks for example beforeValidate() or beforeSave() where in your case it should be better to use beforeValidate since you'd probably also want to validate this data afterwards.

You should also notify the user that the input will be trimmed and maybe also do such trimming on the client-side (before the POST) - check this StackOverflow answer out.
