Fatal error: Call to a member function isError() on null

[mahmoud-m-abadi]

Hi,

I'm using PHRETS2, but sometimes I got the error below when I used GetObject to get images and I put this code "if(!$images->first()->isError())" after that. Error: "Fatal error: Call to a member function isError() on null"

Why this happened?

Regards,

I'm guessing that for your $images, there aren't actually any, so calling first() returns null and then you call isError() on that. It's probably best to wrap that in an if (count($images)) check before proceeding

@steveheinsch Yes, actually I already used this method. Thanks!

Hey sir.

We have a problem that can not be solved, so we ask you for help 。

First of all, we have MLS accounts that you got from them. They are:

  $rets_login_url = "https://pt.rets.crmls.org/contact/rets/login";
    $rets_username = "**FANG";
    $rets_password = '**!y$jTv'; 

I can make sure this account is available，I can make sure this account is available, because I can get the data through this account(That is the basic information Housing)，

I got the data through this phprets 1.x and put it in the CSV, which is what we need。

I see your document is using this method: GetObject ("property", "photo", "*", "1") ,to get the picture.

There are a lot of mlsid fields involved in CSV, but I don't know which field to associate to get the corresponding picture.

So please help me, thank you very much!!!

     Good nice to you!!!

Hi @1014825794 Actually CRMLS returns the images in another resource called Media, rather than 'property'. So you need to get 'ListingKeyNumberic' and make a search in MLS data with 'Media' in resource and class parameters.

Thank you very much, and I need to use that method in order to get the picture. I've got the data and put it in the CVS. It has ListingKeyNumberic, Thanks!!!

@1014825794 Maybe the relevant listing has just one image! send me what you made for searching images.

[1014825794]

There shouldn't be only one. All you get is just one. I get it in CVS by getting what media has. Can you tell me how you did it? Here is the information I pulled to get the media:

$property_classes = array("Media"); foreach ($property_classes as $class) {

    echo "+ Property:{$class}\n";

    $file_name = strtolower("property_{$class}.csv");
    $fh = fopen($file_name, "w+");

    $maxrows = true;
    $offset = 1;
    $limit = 1000;
    $fields_order = array();

    while ($maxrows) {

            $query = "(MediaType=Image),(TimestampModified=2000-01-01T00:00:00+),(ClassKey=8+)";

            // run RETS search
            echo "   + Query: {$query}  Limit: {$limit}  Offset: {$offset}\n";
            $search = $rets->SearchQuery("Media", $class, $query, array('Limit' => $limit, 'Offset' => $offset, 'Format' => 'COMPACT-DECODED', 'Count' => 1));

            if ($rets->NumRows() > 0) {

                    if ($offset == 1) {
                            // print filename headers as first line
                            $fields_order = $rets->SearchGetFields($search);
                            fputcsv($fh, $fields_order);
                    }

                    // process results
                    while ($record = $rets->FetchRow($search)) {
                            $this_record = array();
                            foreach ($fields_order as $fo) {
                                    $this_record[] = $record[$fo];
                            }
                            fputcsv($fh, $this_record);
                    }

                    $offset = ($offset + $rets->NumRows());

            }

            $maxrows = $rets->IsMaxrowsReached();
            echo "    + Total found: {$rets->TotalRecordsFound()}\n";

            $rets->FreeResult($search);
    }

    fclose($fh);

    echo "  - done\n";

}

Thank you very much!!!

@1014825794 Actually I just did search in Media class with this query: (ListingKeyNumberic=123456) And it returns all images.

[1014825794]

Thank you very much for your help. I have been able to get the picture, but I have a new problem,I have access to relevant information listings, but in the acquisition of the contents inside, but not listing the longitude, and the broker and contact head, and so on, I would like to ask what is the reason I can't get these contents, how can I get the information, ask you to tell me what to do??? Thank you very much.
