Immoscout24 Import for Contao

This bundle allows you to import real estate objects from Immoscout24 into your Contao application (4.8+) and display them as native content.

Warning: This is an early release. There might be features missing. Use at your own risk.

How to get going

Setup

1. Install the bundle and update your database. There is no further configuration necessary.

   composer require derhaeuptling/contao-immobilienscout24-import-bundle

2. Add at least one Immoscout24 Account in the backend and enter your API credentials.

3. Setup a cron job that executes the immoscout24:sync command or run it yourself to import real estate objects from the API into your application. You can pass an account's id or description as a parameter to only sync this one account and --dry-run to only see what would be updated without persisting the changes. Use the option --purge to clear the database table and all downloaded files completely beforehand.

4. We are using Contao's Virtual Filesystem feature. If you also want to adjust where the downloaded attachments should be stored, simply mount the immoscout24 directory at another place. See the Contao developer docs for more information about this topic.

5. Add one or more Immoscout24 modules in your theme and use it in the frontend:

   • The Real estate list displays a list of real estate objects. If you want to generate a teaser list with 'read more' links, make sure to specify a 'jump to' page with the appropriate reader.

   • The Real estate reader displays a single real estate object based on the url parameter (id).

   • List items can be constrained individually by using a filter expression.
     Some filter expression examples:

     • one object by its ID realEstateId == 111111111
     • some objects by its IDs realEstateId in [111111111,222222222,333333333]
     • all active objects state == STATUS_ACTIVE
     • all objects published to the homepage channel 'Homepage' in publishChannels
     • all objects with empty API-Searchfield1 apiSearchData1 != null
     • all objects that match a KEYWORD in the title field title matches "/KEYWORD/"
     • combine filter 'Homepage' in publishChannels && priceMarketingType == "Kauf"

Templates and values

The real estate listings contain lots of fields - most likely you'll want to adapt the templates to your needs and only output some of the fields. To do this, there are some helpers for your convenience.

A) Real estate data comes in the form of an entity instance, you can type hint against it to get IDE auto-completion in your templates:

  /** var Derhaeuptling\ContaoImmoscout24\Entity\RealEstate $realEstate */
  $realEstate

B) You can also obtain a list of all available attributes:

  $this->attributes

  // array [name => label] of publicly accessible fields of the real estate objects
  // e.g. 'descriptionNote' that can be accessed via $realEstate->descriptionNote

C) To retrieve and format data, you can use these helper functions:

  $this->hasData(RealEstate $realEstate, string $attribute) : bool
  // will return wether $realEstate holds data for the $attribute

  $this->getFormatted(RealEstate $realEstate, string $attribute) : string
  // will return the formatted value of $attribute - enumerations, dates and
  // booleans will resolved to a string representation based on the language
  // files

D) If you want to resolve enumerations yourself you can find all of them as public constants in the RealEstate entity.

Some enumeration values can occur multiple times per value. In this case they are implemented as binary flags:

  FLAG__TYPE_A = 1;
  FLAG__TYPE_B = 2;
  FLAG__TYPE_C = 4;
  FLAG__TYPE_D = 8;
  FLAG__TYPE_E = 16;

  // n-of-value selecting 'type A' and 'type E'
  $value = -(FLAG__TYPE_A | FLAG__TYPE_E); // = 17

Note that flagged values are stored as negative numbers, so that they can easily be differentiated from regular enumeration values.

Attachments

Real estate objects can have multiple attachments. Note: that currently only images are supported attachment types.

To render an attachment (as an image) you can utilize the getFigureFromAttachment() function present in the templates. It allows passing in an alternative image size as second argument:

  $figure = $this->getFigureFromAttachment($realEstate->getTitlePictureAttachment());

  $figure = $this->getFigureFromAttachment(
      $realEstate->getTitlePictureAttachment(),
      $this->alternativeImageSize
  );

To output the Figure, pass its data to the template you want render. In case of the legacy image template, make sure to expand the image data beforehand by calling getLegacyTemplateData():

  $this->insert('image', $titlePictureFigure->getLegacyTemplateData());

Here is the full example how to output the title picture with the default image size in a failure-tolerant way:

    <div>
        <h2>Title Picture</h2>
        <?php if(null !== ($titlePictureFigure = $this->getFigureFromAttachment($this->realEstate->getTitlePictureAttachment()))): ?>
            <?php $this->insert('image', $titlePictureFigure->getLegacyTemplateData()); ?>
        <?php else: ?>
            <span>There is no title picture.</span>
        <?php endif; ?>
    </div>
