Keep in mind that when using normal articulation at Limesurvey, these always must start as well as finish with a reduce (“& ldquo;/ & rdquo;-RRB-.

rdquo; and also & ldquo; email2 & rdquo;:((! is_empty( email1.NAOK) as well as! is_empty( email2.NAOK) )) This equation must right now be extended so that the alerting only turns up if both text inputs put on’& rsquo; t fit and the excellence notification is merely revealed if each strands are equal:
Alert information: (( email1.NAOK!= email2.NAOK and also! is_empty( email1.NAOK) and! is_empty( email2.NAOK)))

; t suit To cease the individual from continuing a questionnaire even when the email and email verification handle don’& rsquo; t match our team have to develop our very own recognition function. Due to the fact that Limesurvey 1.92 this can be performed by utilizing the Expression Supervisor and also the “& ldquo; Whole question validation formula“& ldquo;. Our experts can easily even generate our very own mistake information.
The distinction at the questionnaire layout is that our company are now using a multiple brief text message question type to have two text areas within the exact same inquiry for later question validation.
The recognition formula we desire to establish should check
- if message was actually suggestionsed at industry 1 (email deal with) -> > area might certainly not be unfilled
- if message was actually suggestionsed at field 2 (email proof) -> > field might certainly not be actually empty
- if the inputted text message strands match the normal expression for valid email handles
- if each message areas have the same strands -> > emails_1 == emails_2
Thinking that the concern code of our question is “& ldquo; emails & rdquo; as well as the sub-question codes are actually “& ldquo; 1”& rdquo; as well as & ldquo; 2 & rdquo;, we can easily make use of the “complying with string at the & ldquo; Question recognition equation & rdquo; field which can be discovered at the enhanced question environments:
(! is_empty( emails_1. NAOK). AND. regexMatch('/ ^.+? @.+? \.+$/', emails_1. NAOK). AND ALSO. (! is_empty( emails_2. NAOK). or. regexMatch('/ ^.+? @.+? \.+$/', emails_2. NAOK)). As Well As. ( emails_1. NAOK == emails_2. NAOK))
To reveal different mistake messages depending on to the current state of both input fields, our team can place the following equations in to the “& ldquo; Concern validation idea” & rdquo; listed below:
^.+? @.+? \.+$ ^. +? @. +? \. + $ if(! is_empty (emails_1. NAOK ). as well as. ! is_empty (emails_2. NAOK). and also. emails_1. NAOK = = emails_2. NAOK,. 'Em ail deals with match!',. 'Em ail address and also email verification do CERTAINLY NOT match!')
