为什么上传到数据库时会收到 PDO 异常

Question

I am trying to upload some data to a MySQl DB using a PDO object. However, whenever I attempt to submit the query it throws a PDOException. I have followed multiple tutorials by the book and this should be a simple task. I have no idea why it throws an exception.

Here is my code:

    // Add a new image data to db and return ID (ID column of pelagicsschema.images)
    public  function addImage(string $name, string $species, string $rarity, string $description){
    //Global PDO Object
    global $pdo;
    //trim strings to remove extra spaces
    $name = trim($name);
    $species = trim($species);
    $rarity = trim($rarity);
    $description = trim($description);



   // Add the new Image

   /* Insert query template */
   $query = 'INSERT INTO pelagicsSchema.images (Name,Species,Rarity,Description) VALUES    (:name,:species,:rarity,:description)';
   /* Values array for PDO */
   $values = array(':name'=>$name, ':species'=>$species, ':rarity'=>$rarity, ':description'=>$description);
   /* Execute the query */
   try
   {
       $res = $pdo->prepare($query);
       $res->execute($values);
   }
   catch (PDOException $e)
   {
      /* If there is a PDO exception, throw a standard exception */
      throw new Exception('Database query error');
   }

       /* Return the new ID */
        return $pdo->lastInsertId();
    }

To Note: The query executes perfectly if I use exec() instead of prepare/execute, but as this request will be made multiple times with different data, I believe prepare/execute is the way to go.

EDIT: The Exception that I am receiving is:

SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column 'Name' at row 1

Does this mean I need to change the datatype for that column in my DB? Currently it is set to VARCHAR(30).

Answer 1

It looks like you are trying to insert data that is longer that the column definition's maximum size.

If you wanna store strings bigger than 255 characters, you should use another type for the name column definition, text for example.
