Question

I am currently plowing my way through IBM’s tutorial on CakePHP

At one point I run into this snippet of code:

<?php class Dealer extends AppModel {     var $name = 'Dealer';     var $hasMany = array (         'Product' => array(             'className' => 'Product',             'conditions'=>, // is this allowed?             'order'=>, // same thing here             'foreignKey'=>'dealer_id'         )     ); } ?> 

When I run it I get the following error-message: ‘Parse error: syntax error, unexpected ‘,’ in /Applications/MAMP/htdocs/cakephp/app/models/product.php on line 7′

I’m a n00b at PHP so my question is: is it allowed to make an array with keys without assigned values? Has anybody played around with this tut and know what is up?

Answer 1

Assign the value null instead of leaving anything out. The manual says

isset() will return FALSE if testing a variable that has been set to NULL

<?php     class Dealer extends AppModel     {         var $name = 'Dealer';         var $hasMany = array(             'Product' => array(                 'className' => 'Product',                 'conditions' => null,                 'order' => null,                 'foreignKey' => 'dealer_id'             )         );     } ?> 

This works fine.
