Conditional Statements for XenForo 2

[AcidCat]

As far as I know, that's not possible only with template conditionals.

javascript it is then.

Great!

Should this:

6. How can I show different content to members and guests?

Code:
<xf:if is="!$xf.visitor.user_id">
Show only members
<xf:else />
Show only guests
</xf:if>

not be:

6. How can I show different content to members and guests?

Code:
<xf:if is="$xf.visitor.user_id">
Show only members
<xf:else />
Show only guests
</xf:if>

?

The "!" could be too much?

How to check if user watching thread is admin or moderator? I tried with this code:

3. How can I show content to Administrators and Moderators?

<xf:if is="$xf.visitor.is_admin OR $xf.visitor.is_moderator">
Show content...
</xf:if>

I need it for this example: https://xenforo.com/community/threads/last-seen-date.196828/post-1571980

To the best of my knowledge this should work; i don't see a reason why it wouldn't..

To the best of my knowledge this should work; i don't see a reason why it wouldn't..

This is error I get:

Line 28: Found a contentcheck tag without a contentcheck-based if tag. - Template modifications: public:message_macros

And I used it like this for example I mentioned:

$0

                    <xf:if is="$xf.visitor.is_admin OR $xf.visitor.is_moderator">
                    <dl class="pairs pairs--justified">
                        <dt>{{ phrase('last_seen') }}</dt>
                        <dd dir="auto">
                            <xf:contentcheck><xf:useractivity user="$user" class="pairs--plainLabel" /></xf:contentcheck>
                        </dd>
                    </dl>
                    </xf:if>

The error message says all

You can try adding 2 lines:

$0

                    <xf:if is="$xf.visitor.is_admin OR $xf.visitor.is_moderator">
<xf:if contentcheck="true">
                    <dl class="pairs pairs--justified">
                        <dt>{{ phrase('last_seen') }}</dt>
                        <dd dir="auto">
                            <xf:contentcheck><xf:useractivity user="$user" class="pairs--plainLabel" /></xf:contentcheck>
                        </dd>
                    </dl>
</xf:if>
                    </xf:if>

Thanks, this solved this problem.

Hi, how would you handle an apostrophe when writing an if conditional statement, example, if the data was "Jack's iPhone", that apostrophe would conflict with the statement:< xf:if is="{$xf.visitor.Profile.custom_fields.PhoneName} == 'Jack's iPhone'">

Just wondering how to correctly fix this.

 

[Old Nick]

Did you try <xf:if is="{$xf.visitor.Profile.custom_fields.PhoneName} == 'Jack\'s iPhone'"> ?
It's really random... no certainty on that.

I just tried that, unfortunately it didn't work, I originally tried putting a back slash before and after it.

How about...

<xf:if is="{$xf.visitor.Profile.custom_fields.PhoneName} == 'Jack'\''s iPhone'">

 

[Dragonfruit]

How about...

<xf:if is="{$xf.visitor.Profile.custom_fields.PhoneName} == 'Jack'\''s iPhone'">

Unfortunately not

 

[nocte]

Try this:

<xf:set var="$var" value="Jack's iPhone" />
<xf:if is="{$xf.visitor.Profile.custom_fields.PhoneName} == $var">

untested, but may work.

No luck, but thanks for trying!

Why is it not working in XenForo?

If I do that via PHP it works:

if (!(FALSE OR TRUE OR TRUE)) {
    echo "5)\n";
}

if (!(FALSE AND TRUE AND TRUE)) {
    echo "6)\n";
}

Result:
6)

but in Xenforo not:

<xf:if is="(!(FALSE OR TRUE OR TRUE))">
FTT.
</xf:if>

<xf:if is="(!(FALSE AND TRUE AND TRUE))">
FTT and.
</xf:if>

Result:
FTT.
FTT and.

and why does array_intersect do not work.

<xf:if is="(array_intersect([3,4], [3,4,5,6]))">
Result
</xf:if>

Template code is not a substitute for PHP.

The is attribute supports logical operators:

• OR / || - used to link alternative conditions
• AND / && - used to link additional conditions
• ! - place before a condition to invert it
• XOR - returns true if only one of two conditions is true

Look at src/XF/Template/Templater.php to see what filters and functions are available - array_intersect is not.

! - place before a condition to invert it

Thanks for your feedback, and how do I get the examples above to work with inverting?

Interesting question!

I gave your code a test run and it was compiled to:

    if (!(false OR true) OR true) {
        $__finalCompiled .= '
FTT.
';

Template code is not a substitute for PHP.

Yeah, but this seems to be a bug in XF core, because the template code is translated to something different.

Bug-report:

Fixed - Templates: "if" conditions in some cases not translated correctly into PHP

If you have this if condition in a template: FTT. then the compiled PHP code looks like this: if (!(false OR true) OR true) { $__finalCompiled .= ' FTT. '; It would be expected that nothing was printed, but because of falsely set brackets (!(false OR true), the outcome is...

How did you get the compiled code?

How did you get the compiled code?

I searched for the string FTT.. You can find the compiled templates in internal_data/code_cache/templates.
