Next Entry/Previous Entry code?

I found a Japanese blog post explaining how to do it.

You can use this example in mt:Entries or Entry Archive.

<mt:IfNonEmpty tag="EntryCategory">
    <$MTEntryCategory setvar="entcat"$>
    <$MTEntryDate format="%Y%m%d%H%M%S" setvar="curdate"$>
 
    <$mt:SetVar name="entall" value="0"$>
    <MTEntries category="$entcat">
        <mt:SetVarBlock name="entdate[$entall]"><$MTEntryDate format="%Y%m%d%H%M%S"$></mt:SetVarBlock>
        <mt:SetVarBlock name="entname[$entall]"><$MTEntryTitle$></mt:SetVarBlock>
        <mt:SetVarBlock name="entlink[$entall]"><$MTEntryPermalink$></mt:SetVarBlock>
        <$mt:SetVar name="entall" value="1" op="+"$>
    </MTEntries>
 
    <ul>
    <mt:For var="x" from="0" to="$entall" increment="1">
        <mt:If name="entdate[$x]" eq="$curdate">
            <mt:SetVarBlock name="idx"><$mt:GetVar name="x" value="1" op="+"$></mt:SetVarBlock>
            <mt:If name="idx" lt="$entall">
                <li class="list_entry">Prev Page: <a href="<mt:GetVar name="entlink[$idx]">" title="Previous"><mt:GetVar name="entname[$idx]"></a></li>
            </mt:If>
 
            <mt:SetVarBlock name="idx"><$mt:GetVar name="x" value="1" op="-"$></mt:SetVarBlock>
            <mt:If name="idx" ge="0">
                <li class="list_entry">Next Page: <a href="<mt:GetVar name="entlink[$idx]">" title="Next"><mt:GetVar name="entname[$idx]"></a></li>
            </mt:If>
            <mt:SetVar name="x" value="$entall">
        </mt:If>
    </mt:For>
    </ul>
<mt:Else>
    <ul>
    <MTEntryPrevious><li class="list_entry">Prev Page: <a href="<$MTEntryPermalink$>" title="Previous"><$MTEntryTitle encode_html="1"$></a></li></MTEntryPrevious>
    <MTEntryNext><li class="list_entry">Next Page: <a href="<$MTEntryPermalink$>" title="Next"><$MTEntryTitle encode_html="1"$></a></li></MTEntryNext>
    </ul>
</mt:IfNonEmpty>

Great! That code works well! Thank you.

I doesn't go to the next category when it gets to the end of the current one, but I like what it is doing with the next and previous posts within the same category.

Thanks!

I have some similar (but shorter) code on my blog:
