    resolved [RESOLVED] mysql_query is performing several queries instead of just one

    Hi all,

    I have been writing my website and have ended up starting a sort of MVC (model-view-controller) framework, which has made lots of sense to write.
    The problem I have is in my basic model. When I want it to insert a new record, instead of inserting one row, it inserts about five, all with the same properties (except the IDs, which is dealt with by MySQL itself). I checked the SQL query, and it is correct. I tested it by writing it directly into PHPMyAdmin and it only inserted one row.

    The model's method looks like this:
    PHP Code:
    function insert() {
            
    $sql "INSERT INTO " $this->table "
            ("
    ;
            foreach(
    $this->fields as $attr) {
                if(!
    $this->blacklisted($attr) && $attr != $this->primaryKey) {
                    
    $sql .= $attr ", ";
                }
            }
            
    $sql substr_replace($sql"", -2);
            
    $sql .= ") VALUES (";
            foreach(
    $this->fields as $attr) {
                if(!
    $this->blacklisted($attr) && $attr != $this->primaryKey) {
                    
    $sql .= "'" $this->{$attr} . "', ";
                }
            }
            
    $sql substr_replace($sql"", -2);
            
    $sql .= ")";
            
            
    $this->con->query($sql);
        } 
    The connector class for the database has a query() method which looks as follows:
    PHP Code:
    function query($sql null) {
            
    $sql str_replace(array("\"""\\"), array("'"""), $sql);
            
    $this->result mysql_query($sql) or $this->error("Unable to query database: " mysql_error($this->con) . ".");
            return 
    $this->result;
        } 
    The SQL produced (using die($sql)) looks like this:

    Code:
    INSERT INTO artworks (name, date, modified, type, category, collection, comment, public, keywords) VALUES ('test1', '2009-08-12', '2009-08-12', '1', '', '', 'This is a test.', '', 'test, first')
    This really is quite confusing, any help would be much appreciated.
