This extra is discontinued. It was originally built by Sterc and distributed by modmore as a Premium Extra, however in 2020 Sterc decided they can no longer offer the support required. It is no longer available from modmore, but may be available elsewhere.
Unfortunately modmore cannot provide standard support for this extra. You may request support from Sterc directly or consider booking Premium MODX Support if you need help with it.
To prevent spam, you can use the Math hook that ships with FormIt.
Create a custom field
Go to Extras > Formalicious and click on Admin Panel in the top right. On the Field Types tab, create a new field type, providing the following information:
- Name: a name of your choosing to describe the field, for example
- Chunk Template:
customMathFieldTpl(we’ll create this chunk momentarily)
- Leave the values question unchecked and define no chunk for values
- Leave validators empty as well. While the Math hook docs mention making the math field required, that does not work by specifying the validator on the field type in Formalicious. (Formalicious uses
field_IDnames for the fields, while the Math hook expects a hardcoded
Save, and create a new chunk called
customMathFieldTpl with the following:
<div class="row"> <div class="form-group col-xs-12"> <label>[[!+fi.op1]] [[!+fi.operator]] [[!+fi.op2]]?</label> [[!+fi.error.math]] <input type="text" name="math" value="[[!+fi.math]]" /> </div> </div>
Now you’re ready to use the field.
Add the field to a form
Go to Extras > Formalicious and edit your form.
Add the newly created
Math Captcha field to your form. You can give it a title, but that’s not currently used in the
customMathFieldTpl, so is only shown in the form management.
Next open the Advanced tab, and add
math to the Posthooks. This makes sure the field is validated and that error messages are shown.
Important: the math hook only works with forms that only have a single step.
