Class

DatabaseSelectTestCase

Test the SELECT builder.

Code

function testVulnerableComment() {
  $query = db_select('test')->comment('Testing query comments */ SELECT nid FROM {node}; --');
  $name_field = $query->addField('test', 'name');
  $age_field = $query->addField('test', 'age', 'age');
  $result = $query->execute();

  $num_records = 0;
  foreach ($result as $record) {
    $num_records++;
  }

  $query = (string) $query;
  $expected = "/* Testing query comments SELECT nid FROM {node}; -- */ SELECT test.name AS name, test.age AS age\nFROM \n{test} test";

  $this->assertEqual($num_records, 4, 'Returned the correct number of rows.');
  $this->assertEqual($query, $expected, 'The flattened query contains the sanitised comment string.');
