POHow to handle erroneous argument type in this situation?
text
Body
copied!<p>I'd like to use stdClass to store options for some methods, instead of passing huge lists of variables (inspired by javascript-style coding) </p> <p>However, I'd like to make sure I'm always getting an instance of stdClass as an argument. I know I can add a hint in the argument (gb::search below) but when I deliberately try to break it, I'm not sure how to handle the error.</p> <p>Any tips?</p> <pre><code>class gb extends CI_Model { protected $searchtypes = array('full','partial'); protected $endpoint = "https://local.endpoint"; function __construct() { parent::__construct(); // sample search $options = new stdClass(); $options->term = 'sample search'; $options->type = 'full'; $this->search($options); } function clean_term($term){ $term = trim($term); return $term; } function search(stdClass $options){ $term = $options->term; $type = $options->type; // make sure we're doing a valid search if (!$term || !in_array($type, $this->searchtypes)) { return false; } $term = $this->clean_term($term); // etc } </code></pre> <p>The error it throws is something like:</p> <pre><code>A PHP Error was encountered Severity: 4096 Message: Argument 1 passed to gb::search() must be an instance of stdClass, null given, called in /application/models/gb.php on line 20 and defined Filename: models/gb.php Line Number: 29 A PHP Error was encountered Severity: Notice Message: Trying to get property of non-object Filename: models/gb.php Line Number: 31 A PHP Error was encountered Severity: Notice Message: Trying to get property of non-object Filename: models/gb.php Line Number: 32 </code></pre> <p>Any ideas how to approach this from a CodeIgniter point of view?</p>
