Keeping Square Brackets Intact When Outputting TV Content

Template variables are often used for simple text, image paths, or settings. Problems begin when a TV stores JavaScript fragments or array-like structures that contain square brackets. When those values are output directly, the parser may interpret part of the content as Evo tags and strip or distort it.

Why it happens

Evolution CMS uses square-bracket syntax for its own tags. If your TV contains nested brackets that resemble parser syntax, rendering it as plain template output can produce incomplete results.

Safer approaches

• store structured data as JSON and decode it in a snippet before output
• escape or transform the content before sending it into the template
• move JavaScript configuration into a chunk or snippet that explicitly controls output

Practical recommendation

Do not treat a textarea TV as a raw code transport unless you fully control how it is rendered. For configuration arrays, JSON is usually the safest option because it is easier to validate and easier to process in both PHP and JavaScript.
