Helper Class to generate a unique key from the values of an array. I have a home page search form where user selects different option to go next page. If I save the search in session User cannot make multiple orders be opening in a new tab.The only solution is to pass the search fields in the url. Since there is a limitation of the url length . I want to generate a hash value of the search data and pass it on to the url. Is there a better way to generate the hash value.
Only simple solution I have found is woocommerce cart key generation which uses md5 to generate the key.
class HashKey extends Object
{
public $model;
public $hashkey;
public function __construct($model)
{
$attributes = $model->getAttributes();
if ( is_array( $attributes ) && ! empty( $attributes ) ) {
$hashkey = '';
foreach ( $attributes as $key => $value ) {
if ( is_array( $value ) ) $value = http_build_query( $value );
$hashkey .= trim($key) . trim($value);
}
$id_parts[] = $hashkey;
}
$this->hashkey = md5( implode( '_', $id_parts ) );
}
/**
* String magic method
* @return string the DB expression
*/
public function __toString()
{
return $this->hashkey;
}
}
