FlowQuery groupBy operation to group arrays by EEL discriminator
Once upon a time I had a list of persons nodes, and I needed to group them by first letter. So I decided there should be a generic way to group array of nodes into subgroups, based on an EEL expression... And here it is!
TL;DR
Install: composer require dimaip/groupby
Use:
groupedNodesByFirstLetterOfLastName = ${q(nodes).groupBy('String.substring(node.properties.lastName, 0, 1)')}
Full example
Once you have grouped the nodes, you can render them any way you like: with Fluid (yikes!) or with Fusion (yay!).
prototype(Name.Space:GroupedList) < prototype(TYPO3.TypoScript:Collection) {
@process.tmpl = ${'<div class="grouped-list">' + value + '</div>'}
@context.nodes = ${q(site).find('[instanceof Name.Space:Person]')}
collection = ${nodes.groupBy('String.substring(node.properties.lastName, 0, 1)')}
itemName = 'nodes'
itemKey = 'firstLetter'
itemRenderer = TYPO3.TypoScript:Collection {
@process.tmpl = ${'<div><h2>' + firstLetter + '</h2><ul>' + value + '</ul></div>'}
collection = ${nodes}
itemName = 'node'
itemRenderer = ${'<li>' + node.properties.firstName + ' ' + node.properties.lastName + '</li>'}
}
}
In a similar way you can group nodes based on a very complex EEL expressions, let your imagination fly!
