php - Control user access and relations to nodes and their authors in Drupal 7 -


i trying following in drupal 7:

users in website post ads , others pay in touch author of ad. users buying contact information have see of content of ad(node), except author. after pay, should see field in ad, telling them author is.

my question is: how can control user access per node , per user specific part of node? there modules this? also, relation between user , ad nice, since later have list ads user, etc..

i found many plugins, seem deny or allow access entire node , functionality should different.

thanks in advance

in order allow specific users or roles view specific nodes, module can you:

https://www.drupal.org/project/nodeaccess

also, want restrict permission field, field permissions module can work you:

https://www.drupal.org/project/field_permissions

of course might need write custom code or use rules module grant permission users going allowed see nodes/fields based on actions on website.

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 .
