html - Handling post and session values in form submit PHP -


i have code this. i'm trying is:

  1. check whether post values there, if yes - execute query , display result.
  2. or check session value, if session there play session value , display result.

when print session value, getting printed (i.e author_id there in session) not coming inside if loop. why?

in other words, want check post values or session value, , display record accordingly.

ps: if remove || condition (i.e isset ( $_session ['author_id'] ) ) code words perfect. 

    <?php      session_start();     print_r($_session);     if (isset ( $_post ['submit'] )  ||  isset ( $_session ['author_id'] )) {             .. post values or session values ..      }     ?>      <form method="post" id="myform1" name="myform1">     ........... form fields..............     <input type="submit" name="submit" value="submit" />     </form>

important: instead of using session or cookie, there way handle form input field values in same page?

try check $_post

if (isset( $_post)||isset ( $_session ['author_id'] )) {             .. post values or session values ..      }

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
