Why url parameter is indexed at 'named' instead of 'pass' in cakephp?

My url is: http://localhost/intranet/customers/search/1/1A%3A79%3A32%3A97%3AF2/1 I am printing the params object as follows:

print_r($this->params);

This print the following array:

[params] => Array
        (
            [plugin] => 
            [controller] => customers
            [action] => search
            [named] => Array
                (
                    [1A] => 79:32:97:F2
                )

            [pass] => Array
                (
                    [0] => 1
                    [1] => 1
                )

        )

but it should print:

[params] => Array
        (
            [plugin] => 
            [controller] => customers
            [action] => search
            [named] => Array
                (

                )

            [pass] => Array
                (
                    [0] => 1
                    [1] => 1A:79:32:97:F2
                    [2] => 1
                )
        )

But when I change the url like: http://localhost/intranet/customers/search/1/abc/1

[params] => Array
        (
            [plugin] => 
            [controller] => customers
            [action] => search
            [named] => Array
                (

                )

            [pass] => Array
                (
                    [0] => 1
                    [1] => abc
                    [2] => 1
                )
        )

Which problem with 1A:79:32:97:F2 as parameter in url?

Solution

You need to disable the greediness of named parameter parsing, by default all parameters that look like named parameters are being parsed as such (that is values that contain the : separator).

In your routes configuration, use the second argument of Router::connectNamed() to pass further options, something along the lines of this, which would enable only the default CakePHP pagination paramters:

Router::connectNamed(
    false, // no custom named parameters
    array(
        'default' => true, // default pagination parameters
        'greedy' => false  // no greediness
    )
);
