通过数据库查询进行Drupal 6表单迭代

Question

I'm trying to run a foreach over an array pulled from a db query but for some reason it isn't working. Is this a simple syntax error or something else?

  global $user
  $ras = db_query("SELECT * FROM {table} WHERE id='%s'", $user->name); 
  $sas = db_fetch_array($ras);  
  $arr = array("one",2,3,"four",5);

  $form['questionnaire'] = array (
    '#type'=>'fieldset', 
    '#title'=> 'test', );

  foreach ($arr as $id => $value){ 
  $form['questionnaire']['fill'.$id] = array(
    '#type'=>'textfield',
    '#title'=> $value,
  );
  }

However, the following wont work:

  foreach ($sas as $id => $value){ 
  $form['questionnaire']['fill'.$id] = array(
    '#type'=>'textfield',
    '#title'=> $value,
  );
  }

Answer 1

Unless your query returns a single result, which I doubt since you're expecting an array of results, your syntax is missing something. db_fetch_array will only fetch one row. So you need to do something like this.

$form['questionnaire'] = array(
  '#type' => 'fieldset',
  '#title' => 'test',
);

global $user;
$result = db_query("SELECT * FROM {table} WHERE id='%s'", $user->name);

// Remember that $row is an array where the key names map the column names in your table
// So if you have a column 'id' and another one 'value' you can access the
// value for one row like this $row['id] and $row['value']
while ($row = db_fetch_array($result)) {
  $form['questionnaire']['fill' . $row['id']] = array(
    '#type' => 'textfield',
    '#title' => $row['column_name'],
  );
}

Update 07.02.2013 : Using a foreach() loop instead of while()

foreach (db_fetch_array ($row) as $row) {
    echo $row['name'];
}

The syntax looks right but the obvious answer is that the query isn't returning any data. Is it possible thst you've forgotten global $user? Devel module can help with this.
