How to enforce safe search with google search cse

Enforce Safe Search by passing name=safe value=vss

I assume VSS stands for Very Safe Search

This will disable the ability for a user to change their safe search settings from strict to off.

Here is an example for you

<form action="http://www.google.com/cse" id="cse-search-box">
  <div>
  <input type="hidden" name="cx" value="000753778363423014722:xie0vouxf9m" />
    <input type="hidden" name="ie" value="UTF-8" />
    <input type="hidden" name="filter" value="1" />
    <input type="text" name="q" size="35" style="font: normal 25px Arial; line-height:25px;" id="q"/>
    <input type="hidden" name="safe" value=vss />
    <input type="submit" name="sa" value="Safe Search" style="font: normal 25px Arial; line-height:25px;" onClick="checksearch()"/>
  </div>
</form>
