php foreach

[romank]

Hi,

I have the following issue.

I am passing a checkbox values to array and adding commas to separate the values. Then I am removing the last comma from the string. The problem is that the $cityid never shows more than one value. For some reason the foreach loop does not get propageded into the echo $cityid = substr_replace ($city_ids,"",-1);

Any ideas? Thanks. Roman

<?

$city_id = $_POST["city_id"];

foreach ($city_id as $value)
  {
  echo $city_ids = ''.$value.','; 
  }

echo $cityid = substr_replace ($city_ids,"",-1);
?>

Never mind. I figured it out. Quite simple..

 $cityid = implode(",", $city_id);

now I can pass my values to my SQL statement

echo $city_sql = "AND e.city_id IN (".$cityid.")";
