You have two ways to do that
1- Through Template modification option under Appearance in your ACP
2- Direct edit of reigester_macros template which I do not recommend because every time you are going to upgrade to newest xf version your edit will be overwritten.
To do step 1 first you have to enable development mode by adding this to your config file
$config['development']['enabled'] = true;
A- Navigate to Apperance> Template modification> add template modifcation.
B- in Template field call the template you are going to modify in this case register_macros
C- in Modification key which is the second field > add something that identifies your modification of your choice for example lets put:
email_notice
D- scroll down to the (find) box and place this code
HTML:
<xf:macro name="email_row"
arg-fieldName="email"
arg-value="">
<xf:textboxrow name="{$fieldName}" value="{$value}" type="email" autocomplete="email" required="required"
maxlength="{{ max_length($xf.visitor, 'email') }}"
label="{{ phrase('email') }}"
hint="{{ phrase('required') }}" />
</xf:macro>
E- go to the replace box and add this code. Change this sentence
with your notice. Make sure not to remove the brackets.
HTML:
<xf:macro name="email_row"
arg-fieldName="email"
arg-value="">
<xf:textboxrow name="{$fieldName}" value="{$value}" type="email" autocomplete="email" required="required"
maxlength="{{ max_length($xf.visitor, 'email') }}"
label="{{ phrase('email') }}"
hint="{{ phrase('required') }}"
explain="{{ ('put your notice here.') }}"/>
</xf:macro>
$1
hit save and you are good to go.
Method number 2
go to template register macros and find this
HTML:
label="{{ phrase('email') }}"
hint="{{ phrase('required') }}" />
replace with this. do not forget to replace this sentence
put your notice here
with your notice.
HTML:
label="{{ phrase('email') }}"
hint="{{ phrase('required') }}"
explain="{{ ('put your notice here.') }}"/>
save.
if you choose method 1 do not forget to disable development mode after you are done by removing
$config['development']['enabled'] = true;
from your config file.
