This library provides for developer-friendly ways to query for or delete Caldera Forms entry data.

Why?

• To provide the types of queries we need for reporting and deleting data in order to add GDPR compliance to Caldera Forms
• To provide the types of queries we need for improving Caldera Forms features such as entry viewer, entry export, entry editing and Connected Forms.

Install

composer require calderawp/caldera-forms-query

Requires

• WordPress - tested with 4.8, latest and trunk
• PHP 5.6+ - tested with PHP 7.1 and 7.2
• Caldera Forms 1.6.0+ - tested with Caldera Forms 1.6.1 beta 1

Status

• Works
• Does not yet select/delete by date range
• Prepared SQL needs to be sanitized better.

Usage

Basic Queries

/**
 * Examples of simple queries
 *
 * Using the class: \calderawp\CalderaFormsQuery\Features\FeatureContainer
 * Via the static accessor function: calderawp\CalderaFormsQueries\CalderaFormsQueries()
 */

/** First make the function usable without a full namespace */
use function calderawp\CalderaFormsQueries\CalderaFormsQueries;

/** Do Some Queries */
//Select all data by user ID
$entries = CalderaFormsQueries()->selectByUserId(42);

//Select all entries that have a field whose slug is "email" and the value of that field's value is "delete@please.eu"
$entries = CalderaFormsQueries()->selectByFieldValue( 'email', 'delete@please.eu' );

//Select all entries that do not have field whose slug is "size" and the value of that field's value is "big"
$entries = CalderaFormsQueries()->selectByFieldValue( 'size', 'big', false );

//Delete all data by Entry ID
CalderaFormsQueries()->deleteByEntryIds([1,1,2,3,5,8,42]);

//Delete all data by User ID
CalderaFormsQueries()->deleteByUserId(42);

Paginated Queries

The selectByFieldValue feature method defaults to limiting queries to 25. You can set the page and limit with the 4th & 5th arguments.

/**
 * Examples of simple queries
 *
 * Using the class: \calderawp\CalderaFormsQuery\Features\FeatureContainer
 * Via the static accessor function: calderawp\CalderaFormsQueries\CalderaFormsQueries()
 */

/** First make the function usable without a full namespace */
use function calderawp\CalderaFormsQueries\CalderaFormsQueries;

/** Do Some Queries */
//Select all entries that have a field whose slug is "email" and the value of that field's value is "delete@please.eu"
//The first 25 entries
$entries = CalderaFormsQueries()->selectByFieldValue( 'email', 'delete@please.eu' );
//The second 25 entries
$entries = CalderaFormsQueries()->selectByFieldValue( 'email', 'delete@please.eu', true, 2 );
//Get 5th page, with 50 results per page
$entries = CalderaFormsQueries()->selectByFieldValue( 'email', 'delete@please.eu', true, 5, 50 );

Constructing Other Queries

The feature container provides helper methods that allow for simple queries like those listed above. It also exposes the underlying query generators.

You can access any of the generators using the getQueries() method. For example:

 $featureContainer = \calderawp\CalderaFormsQueries\CalderaFormsQueries();
    $fieldValue = 'X@x.com';
    $formId = 'CF5afb00e97d698';
    $count = Caldera_Forms_Entry_Bulk::count($formId );

    $entrySelector = $featureContainer
        ->getQueries()
        ->entrySelect();

is() Helper Method

This is a more complete example showing a selection of entry values where the field with the slug primary_email is roy@hiroy.club and the field with the slug of first_name is Mike. It is also using the is() method to add WHERE statements, as well as the addPagination() method to query for the second page of results with 50 results per page.

    $featureContainer = \calderawp\CalderaFormsQueries\CalderaFormsQueries();
    $entrySelector = $featureContainer
        ->getQueries()
        ->entrySelect()
        ->is( 'primary_email', 'roy@hiroy.club' )
        ->is( 'first_name', 'Mike' )
        ->addPagination(2,50 );

in() Helper Method

This example shows selection of all entry values where the entry ID is in an array of entry IDs.

    $featureContainer = \calderawp\CalderaFormsQueries\CalderaFormsQueries();
    $entrySelector = $featureContainer
        ->getQueries()
        ->entrySelect()
        ->in( 'entry_id', [ 42, 3 ] );

Query Generators

All query generators extend the \calderawp\CalderaFormsQuery\QueryBuilder class and impairment \calderawp\CalderaFormsQuery\CreatesSqlQueries.

Query generators are responsible for creating SQL queries. They do not perform sequel queries.

Select Query Generators

Select query generators extend \calderawp\CalderaFormsQuery\Select\SelectQueryBuilder and impliment \calderawp\CalderaFormsQuery\Select\DoesSelectQuery and \calderawp\CalderaFormsQuery\Select\DoesSelectQueryByEntryId.

Useful Methods of SelectQueryBuilders

Using Query Generators To Perform SQL Queries

SELECT

The getQueries() method of the FeatureContainer returns a calderawp\CalderaFormsQuery\Features\Queries instance. This provides us with a select method when passed a SelectQueryBuilder returns an array of stdClass object of results.

        $featureContainer = \calderawp\CalderaFormsQueries\CalderaFormsQueries();
        $entryValueSelect = $featureContainer
            ->getQueries()
            ->entryValuesSelect()
            ->is( 'size', 'large' );

       $featureContainer->getQueries()->select( $entryValueSelect );

You can also access the generated SQL as a string.

  $featureContainer = \calderawp\CalderaFormsQueries\CalderaFormsQueries();
        $sql = $featureContainer
            ->getQueries()
            ->entryValuesSelect()
            ->is( 'size', 'large' )
            ->getPreparedSql();

DELETE

The Queries class also has a delete method we can pass a DeleteQueryBuilder to perform a DELETE query against the database.

WordPress and Caldera Forms Dependency

For now, this library is dependent on Caldera Forms and WordPress (for \WPDB.) This will change, possibly with breaking changes, when caldera-interop is integrated with this tool.
