Question

I am trying to insert a string of given tags into a MySQL table, but it’s not quite working out.

  $tags = array explode (", ", $_POST["tags"]);
  $tag_array = implode(", ", $tags); 

My table has the columns tag_id(auto increment) and tag_name(where each item of array needs to go into)

How do I cycle through my array and make MySQL insert a blank value into tag_id (as it’s auto incremented) and each of my array values into the tag_name column?

You don’t mention how you’re accessing MySQL from within PHP, but using PDO you could do something like this:

$dbh = new PDO("mysql:dbname=$dbname", $username, $password);
$dbh->setAttribute(PDO::ATTR_EMULATE_PREPARES, FALSE);

$insert = $dbh->prepare('INSERT INTO my_table (tag_name) VALUES (:tag)');
$insert->bindParam(':tag', $tag, PDO::PARAM_STR);

foreach ($tags as $tag) $insert->execute();
