mysql - Dynamic CSS with PHP based on database -

found couple answers here on stackoverflow , used them models, must missing something. i'm trying set couple of background colors dynamically in css based on in database, it's not working - when check inspect element in chrome, background-color has line through , warning mark 'invalid property value'.

here's code; it's in 2 separate files - first in header include file, , second in linked .php / css-esque file.

header include: [edited 4/29 include session code]

session_start(); // check if $_session set before if (!isset($_session['email'])) { header("location: bad_login.php"); exit(); }  $_session['companyid'] = $_post['companyid']; $companyid = $_session['companyid']; $email = $_session['email'];  require_once('../includes/_connection.inc.php');  $connect = dbconnect('read'); $sql = 'select colorone, colortwo, logo         companies         companyid = ' . $companyid; $result = $connect->query($sql) or die(mysqli_error()); $row = $result->fetch_assoc(); $colorone = '#' . $row['colorone']; $colortwo = '#' . $row['colortwo']; $carrierlogo = '/companylogos/' . $row['logo']; 

php/css file:

<?php header("content-type: text/css");   ?>  #main {     width: 85%;     margin: 0 auto;     padding: 0.75em 0; }  #colorone {     width: 100%;     height: 12px;     background-color: <?php echo $colorone; ?>; }  #colortwo {     width: 100%;     height: 7px;     background-color: <?php echo $colortwo; ?>; } 

edit 4/29:

this css generated:

#main {     width: 85%;     margin: 0 auto;     padding: 0.75em 0; }  #colorone {     width: 100%;     height: 12px;     background-color: ; }  #colortwo {     width: 100%;     height: 7px;     background-color: ; } 

i echoed variable in html know there should in variable. should opening database , assigning variable inside css.php file?

css/php linked way in header:

<link type="text/css" rel="stylesheet" href="../css/carrier.php"> 

instead of using .css file extension, use .php

in html file: linked .php?

<link rel='stylesheet' type='text/css' href='css/style.php' /> 

in style.php add

<?php     header("content-type: text/css; charset: utf-8"); ?> 

now can set variables whatever like:

source

edit:

don't forget session_start(); since you're using sessions (i don't understand how, since nothing gets posted css/carrier.php should rather have in session different file & use $companyid = $_session['companyid']; $email = $_session['email'];).

is way code looks?

        <?php     session_start();         header("content-type: text/css; charset: utf-8");     $_session['companyid'] = $_post['companyid'];     $companyid = $_session['companyid'];     $email = $_session['email'];      require_once('../includes/_connection.inc.php');      $connect = dbconnect('read');     $sql = 'select colorone, colortwo, logo             companies             companyid = ' . $companyid;     $result = $connect->query($sql) or die(mysqli_error());     $row = $result->fetch_assoc();     $colorone = '#' . $row['colorone'];     $colortwo = '#' . $row['colortwo'];     $carrierlogo = '/companylogos/' . $row['logo'];     ?>  #main {     width: 85%;     margin: 0 auto;     padding: 0.75em 0; }  #colorone {     width: 100%;     height: 12px;     background-color: <?php echo $colorone; ?>; }  #colortwo {     width: 100%;     height: 7px;     background-color: <?php echo $colortwo; ?>; }
