But instead of __FIRST__ we should use another prefix convention, like #VARNAME for variables internal to the template. So $varname for environment variables, %varname for config file variables and #varname for internal template variables. Some variable ideas for sections: #FIRST boolean, true if in the first section loop #INNER boolean, true if after #FIRST #LAST boolean, true if in the last section loop #PREV int, value of previous loop row #LOOP int, value of current loop row #NEXT int, value of next loop row #EVEN boolean, true if current #LOOP value is even #ODD boolean, true if current #LOOP value is odd #TOTAL int, value of total number of rows Also, we may want to define variables within sections, in the case of nested sections with {#sectionname:varname} By default, the current section will be assumed. So an example, we want to color every other row different, and output the total at the bottom: <TABLE> {:section myrows} <TR> <TD bgcolor={:if #EVEN}#ff0000{:else}#00eeff{:/if}> table cell data </TD> </TR> {:/section myrows} There were {#myrows:TOTAL} rows of data. </TABLE>
