PHP CodeIgniter Batch Insert Not Accepting My Array

Question

I'm unable to get the following code to work, and it has something to do with the forming of the array. The array is actually build after a foreach() loop runs a few times, then I want to batch insert, but it comes up malformed. Why?

    foreach ($results as $r) {
$insert_array = array(
                            'ListingRid' => $r['ListingRid'],
                            'StreetNumber' => $r['StreetNumber'],
                            'StreetName' => $r['StreetName'],
                            'City' => $r['City'],
                            'State' => $r['State'],
                            'ZipCode' => $r['ZipCode'],
                            'PropertyType' => $r['PropertyType'],
                            'Bedrooms' => $r['Bedrooms'],
                            'Bathrooms' => $r['Bathrooms'],
                            'YearBuilt' => (2011 - $r['Age']),
                            'Status' => $r['Status'],
                            'PictureCount' => $r['PictureCount'],
                            'SchoolDistrict' => $r['SchoolDistrict'],
                            'ListedSince' => $r['EntryDate'],
                            'MarketingRemarks' => $r['MarketingRemarks'],
                            'PhotoUrl' => (!empty($photo_url) ? $photo_url : 'DEFAULT'),
                            'ListingAgentFirstName' => $r['ListingAgentFirstName'],
                            'ListingAgentLastName' => $r['ListingAgentLastName'],
                            'ContactPhoneAreaCode1' => (!empty($a['ContactPhoneAreaCode1']) ? $a['ContactPhoneAreaCode1'] : 'DEFAULT'),
                            'ContactPhoneNumber1' => (!empty($a['ContactPhoneNumber1']) ? $a['ContactPhoneNumber1'] : 'DEFAULT'),
                            'ListingOfficeName' => (!empty($r['ListingOfficeName']) ? $r['ListingOfficeName'] : 'DEFAULT'),
                            'OfficePhoneComplete' => (!empty($o['OfficePhoneComplete']) ? $o['OfficePhoneComplete'] : 'DEFAULT'),
                            'last_updated' => date('Y-m-d H:i:s')
                        );

                        $insert[] = $insert_array;

}

                        $this->db->insert_batch('listings', $insert);

Here's the errors:

A PHP Error was encountered

Severity: Warning

Message: array_keys() [function.array-keys]: The first argument should be an array

Any ideas? Thanks!

Answer 1

Looks like you need to wrap your array in a second array. You're supposed to provide an array of row arrays.

$insert_array = array(array(...));

Answer 2

I've reduced your code to the bare minimum and it seems to work.

        $i = 0;
        while ($i <= 10) {

            $insert_array = array(
                                        'code' => 'asd'
            );

            $insert[] = $insert_array;
            $i++;
        }


        $this->db->insert_batch('group', $insert);

You should check the elements of the array, comment them all and de-comment them one by one until you got the culprit.
