How to display the average value of two field in postbit
 
Asume that my user table has two columns .One is votetotal and the other is votenum.I can print the value of them in postbit just using : post[votetotal],and post[votenum].However,i only want to print the average value of them when votenum>0 and 0 when votenum<0.
How can i do that?

Are you using a plugin to get the votetotal and votenum? If so, just add the php to get the average. If you aren't using a plugin, you may be able to do the math in the template just take a look at this article - Perform simple calculations inside templates!. If you can't do it in the template, then you'll have to add a plugin.

I tried to do it in the templates.
Quote:
<if condition="$post[votenum]!=0">
<if condition="$rateave = $post[votetotal]/$post[votenum]"></if>
$rateave
</if>
It's okey.However the result is not good looking.
Example if the votetotal is 11,the votenum is 3.It will print 3.6666666666667 .
I just want to get the value 3.67 or 4.

Quote:
<if condition="$post[votenum]!=0">
<if condition="$rateave = $post[votetotal]/$post[votenum]"></if>
<if condition="$rateave >0 && $rateave < 1.5"><if condition="$rateave1=1"></if></if>
<if condition="$rateave >=1.5 && rateave< 2.5"><if condition="$rateave1=2"></if></if>
<if condition="$rateave >=2.5 && rateave<3.5 "><if condition="$rateave1=3"></if></if>
<if condition="$rateave >=3.5 &&rateave<4.5"><if condition="$rateave1=4"></if></if>
<if condition="$rateave >=4.5 "><if condition="$rateave1=5"></if></if>
$rateave1
</if>
Because the maximum rated score is 5 (5 star)I tried to use this and it works.
However,if i want to use the plugin,how can i do that?
Thanks.

You would write the php to do this and probably use a hook location like postbit_display_complete. Plugin System
