FormIt: required validation of a field depending on an other field value

[halftrainedharry]

Here is an example of a custom validator from another thread:

Formit, require at least one of two fields

Something like this should work: [[!FormIt? ... &customValidators=`myCustomValidator` &validate=`field1:myCustomValidator` ]] <form id="myform" action="[[~[[*id]]]]#myform" method="post"> [[!+fi.error.field1]] <input type="text" name="field1" value="[[!+fi.field1]]"> <input type="text" name="field2" value="[[!+fi.field2]]"> ... </form> Snippet myCustomValidator <?php $success = true; if (empty(trim($value))){ // field1 is empty if (isset($validator->fields["field2"…

In the snippet code you can access the value of the field (the validator is attached to) with $value, to get the values of other fields use $validator->fields["your_field_name"].
