Json Formatter

This extension saves input fields and markdown textareas to a Json encoded string (escaping invalid characters: single quote, quotes, backslash, and control characters like \n or \t), to make easier the output of a Json page.

Three text formatters are available:

• Json String for input fields (string formatter)
• Json Title for input fields (string formatted with title case)
• Json CommonMark for textareas (markup formatter)

Dependencies to use all formatters and output a Json page

• Text Box Field to apply string text formatters to an input field
• Content Type Mapping to set up a json page type with the right header

Output a Json Page from Symphony CMS

Make sure to install the Content Type Mapping extension to create a new page with a json type, and set your xsl template as a pure text output:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output
    method="xml"
    omit-xml-declaration="yes"
    encoding="UTF-8"
    indent="yes" />

<xsl:template match="data">{
    "yourdata" : <xsl:value-of select="xpath/to/your/Json/formatted/field/value"/>
}</xsl:template>
