Question

Im trying to figure this out but code isnt working inside of a function on my custom functions page. even if it does run the values arent returned to my reports to add to my $html for later echoing. ideas????

Thanks!!

//**************** page reports.php***********//

include 'db_connect.php';
include 'functions.php';
include 'custom_functions.php';

sec_session_start();
if(login_check($mysqli) == true) {

if($sub_val ==='Jobs In This Week'){ // if week report jobs

            $table = 'jobs';
            $op = 'in';
            $start ='';
            $end = '';

            mkwk();
            sql_prepare($table,$op,$start,$end,$mysqli);


    } // end if jobs report week
        elseif($sub_val ==='Jobs In This Month'){ // if month report jobs
            // functoin to make current month

            mkmth();
            sql_prepare($table,$op,$start,$end);

    } // end if jobs report month

Answer 1

so I figured it out for anyone who doesnt know how to do this either.

the function was working but simply i was not figuring the return values. basicly i needed to set

return $html;

this would send back the html i wanted to be returned and on the other page i would want to either set a value to equal the return or echo the return like so.

$html = sql_prepare(...insert values sent here,$html);

or

 echo sql_prepare(...insert values sent here,$html);

this did the work. thanks for replies
