Examples

All examples are written using HJSON, but if you want you can use vanilla JSON instead.

Get the pagetitle of current document

[[ddGetDocumentField?
	&dataProviderParams=`{
		resourceFields: pagetitle
	}`
]]

Get the introtext of document which ID is 7 and return from chunk

[[ddGetDocumentField?
	&dataProviderParams=`{
		resourceId: 7
		resourceFields: introtext
	}`
	&outputterParams=`{
		tpl: testChunk
	}`
]]

testChunk code:

<div class="test">[+introtext+]</div>

Get the longtitle of a document or pagetitle if longtitle is empty

<title>[[ddGetDocumentField?
	&dataProviderParams=`{
		resourceFields: longtitle
		resourceFieldsAlternative: pagetitle
	}`
]]</title>

Get a few phones from TVs and join them with comma

[[ddGetDocumentField?
	&dataProviderParams=`{
		resourceId: 7
		resourceFields: phone1,phone2
	}`
	&outputterParams=`{
		docFieldsGlue: ", "
	}`
]]

Additional data into result chunk

For example, we are getting something with the Ditto snippet. Into Ditto chunk outputterParams->tpl we need to get phone number & fax, if phone is not empty or nothing. Chunk code:

<div class="test_row">
	[+content+]
	[[ddGetDocumentField?
		&dataProviderParams=`{
			resourceId: "[+id+]"
			resourceFields: phone
		}`
		&outputterParams=`{
			tpl: test_row_phone
			placeholders: {
				fax: "[+fax+]"
				someTitle: Call me!
			}
		}`
	]]
</div>

The test_row_phone chunk code:

<p class="phone" title="[+someTitle+]">[+phone+], [+fax+]</p>

Using field aliases while returning the results in the outputterParams->tpl chunk

[[ddGetDocumentField?
	&dataProviderParams=`{
		resourceFields: pagetitle=title,pub_date=date
	}`
	&outputterParams=`{
		tpl: testChunk
	}`
]]

The testChunk chunk code:

<p>[+title+], [+date+]</p>

Using field aliases with JSON format

[[ddGetDocumentField?
	&dataProviderParams=`{
		resourceFields: pagetitle=title,introtext=text,content
	}`
	&outputter=`object`
]]

Returns:

{
	"title": "The title of a document",
	"text": "The annotation",
	"content": "The content"
}

Remove resource fields with empty values from result

Let that document pagetitle is set and longtitle is empty.

[[ddGetDocumentField?
	&dataProviderParams=`{
		resourceFields: pagetitle,longtitle
	}`
	&outputter=`object`
]]

Returns:

{
	"pagetitle": "The title of a document",
	"longtitle": ""
}

If fields with empty values is no needed, just set outputterParams->removeEmptyFields to true:

[[ddGetDocumentField?
	&dataProviderParams=`{
		resourceFields: pagetitle,longtitle
	}`
	&outputter=`object`
	&outputterParams=`{
		removeEmptyFields: true
	}`
]]

Returns:

{
	"pagetitle": "The title of a document"
}

Return resource fields as a JSON array

[[ddGetDocumentField?
	&dataProviderParams=`{
		resourceFields: pagetitle,longtitle
	}`
	&outputter=`object`
	&outputterParams=`{
		format: stringJsonArray
	}`
]]

Returns:

[
	"The title of a document",
	"The long title of a document"
]

Use templates for fields in JSON

[[ddGetDocumentField?
	&dataProviderParams=`{
		resourceFields: pagetitle,id=link
	}`
	&outputter=`object`
	&outputterParams=`{
		templates: {
			pagetitle: <h1>[+value+]</h1>
			link:
				'''
				<a href="[~[+value+]~]">[+pagetitle+]</a>
				'''
		}
	}`
]]

Returns:

{
	"pagetitle": "<h1>KINO</h1>",
	"link": "<a href=\"bands/timeless/kino\">KINO</a>"
}

Run the snippet through \DDTools\Snippet::runSnippet without DB and eval

\DDTools\Snippet::runSnippet([
	'name' => 'ddGetDocumentField',
	'params' => [
		//Can be set as a native PHP array
		'dataProviderParams' => [
			'resourceId' => 42,
			'resourceFields' => 'pagetitle,question',
		],
	],
]);

Return resource fields as a native PHP array

\DDTools\Snippet::runSnippet([
	'name' => 'ddGetDocumentField',
	'params' => [
		'dataProviderParams' => [
			'resourceId' => 42,
			'resourceFields' => 'pagetitle,question',
		],
		'outputter' => 'object',
		'outputterParams' => [
			'format' => 'objectArray',
		],
	],
]);

Returns:

array(
	'pagetitle' => 'The title of a document',
	'question' => 'What is the meaning of life?',
)
