PHP Error when trying to insert a collections into MongoDB with CodeIgniter and MongoDB driver

Question

I'm building a simple Admin system for an Honours level University project.

Build on Codeigniter with MongoDB using the Alex Bible driver. I'm and trying to carry out a simple insert with hard coded values at the moment.

My Model

$username = "William";
        $email = "Test";
        
        $registerdata = array(
                "username"   => $username,
                "email"      => $email);
        
        $collection = 'students';
        
        $this->mongo_db->insert($collection, $registerdata);

Throwing the following errors:

PHP Error was encountered

Severity: Notice

Message: Undefined variable: insert

Filename: libraries/Mongo_db.php

Line Number: 456

And:

A PHP Error was encountered

Severity: Warning

Message: MongoCollection::insert(): expects parameter 1 to be an array or object, null given

Filename: libraries/Mongo_db.php

Line Number: 456

Any ideas?

It calls this function in the library if that helps any:

     * Insert a new document into the passed collection
     *
     *  @usage = $this->mongo_db->insert('foo', $data = array());
     */
    
     public function insert($collection = "", $data = array()) {
        if(empty($collection))
            show_error("No Mongo collection selected to insert into", 500);
        if(count($data) == 0 || !is_array($data))
            show_error("Nothing to insert into Mongo collection or insert is not an array", 500);
        
        try {
            $this->db->{$collection}->insert($insert, array('safe' => TRUE));
            if(isset($insert['_id']))
                return($insert['_id']);
            else
                return(FALSE);
        } catch(MongoCursorException $e) {
            show_error("Insert of data into MongoDB failed: {$e->getMessage()}", 500);
        }
        
     }

That insert method looks a bit odd. It references a variable called $insert but I cannot see where it gets it from. Did you write that method? If so, maybe you meant $data instead? — halfer

The insert method I'm using comes from the MongoDB driver here : github.com/alexbilbie/codeigniter-mongodb-library/blob/v2/… — user3439929

Your method signature is wrong - I wonder if you have copied and pasted version 2 of this library without installing the whole thing? The new method is:

public function insert($collection = '', $insert = array(), $options = array())

Reinstall the library in your application and check the library files have been pulled in their entirety.

Great. It's worth regarding libraries as "non-editable" - having them as Git submodules or Composer dependencies helps avoid these library+edits problems :).
