Anti Spam Question

Protect your frontend forms by asking random questions.

This extension for Symphony CMS offers an interface to create a set of questions and answers that help protect your frontend forms against spam. It comes with an event filter and a datasource that let you include a random question in your form and return an error if the answer doesn't match.

1. Installation

1. Upload the /anti_spam_question folder in this archive to your Symphony /extensions folder.
2. Go to System → Extensions in your Symphony admin area.
3. Enable the extension by selecting 'Anti Spam Question', choose 'Enable' from the 'With Selected…' menu, then click 'Apply'.

2. Configuration & Usage

1. Go to System → Anti Spam Question and create a few questions and answers.
2. Create an event for your frontend form and include the Anti Spam Question Filter.
3. Attach your created event to your frontend page.
4. Also attach the Anti Spam Question Datasource to your frontend page.
5. Include the following markup in your frontend form.

Example Frontend Form Markup:

<label>
    <xsl:value-of select="//anti-spam-question/entry" />
    <input name="anti-spam-question[answer]" type="text" />
    <input name="anti-spam-question[id]" type="hidden" value="{//anti-spam-question/entry/@id}" />
</label>

Now your frontend form will be populated with a random question and will only succeed if the matching answer will be found in the submitted data. Otherwise the Anti Spam Question Filter will return an error.
