title: Set background color of cells based on MySQL query output
body: <p>I am new to PHP and trying to learn enough to do some basic functions.  I've been able to create a table for my users to edit themselves, and redisplay but I've come across a question. 
  Using the script below, users can input their skill level for various products.  I wanted to be able to highlight each cell in which they input "0" or blank.  User's input will be between 0-5 (or blank if they haven't filled it in yet).</p>
  
  <p>This is all being done on my localhost so I'll admit all the security measures are not quite there.  </p>
  
  <p>I've read a lot of posts and tried to figure it out myself, but I'm doing something fundamentally wrong I believe.  </p>
  
  <p>Any assistance on this would be greatly appreciated.  I've been known to buy a beer (via paypal) for those who help me with coding :)</p>
  
  <p>Here is my existing code for printing out the results of the database:</p>
  
  <pre><code>&lt;?php
  //This will connect to the database in order to begin this page
  mysql_connect("localhost", "root", "time2start") or die (mysql_error());
  //Now we will select the database we need to talk to
  mysql_select_db("joomla_dev_15") or die (mysql_error());
  $query = "SELECT * FROM enterprise_storage WHERE id=1";
  $result = mysql_query($query) or die (mysql_error());
  echo "&lt;table border='1'&gt;";
  echo "$row";
  echo "&lt;tr&gt; &lt;th&gt;Product&lt;/th&gt; &lt;th&gt;Wayne Beeg&lt;/th&gt; &lt;th&gt;Paul Hamke&lt;/th&gt; &lt;th&gt;Steve Jaczyk&lt;/th&gt;       &lt;th&gt;David Jontow&lt;/th&gt; &lt;th&gt;Ed MacDonald&lt;/th&gt; &lt;th&gt;Michael Munozcano&lt;/th&gt; &lt;th&gt;Ron Shaffer&lt;/th&gt;  &lt;th&gt;Luke Soares&lt;/th&gt;  &lt;th&gt;Josh Wenger&lt;/th&gt; &lt;/tr&gt;";
  // keeps getting the next row until there are no more to get
  while($row = mysql_fetch_array( $result )) {
  // Print out the contents of each row into a table
  echo "&lt;tr&gt;&lt;td&gt;"; 
  echo $row['model'];
  echo "&lt;/td&gt;&lt;td&gt;"; 
  echo $row['beeg'];
  echo "&lt;/td&gt;&lt;td&gt;"; 
  echo $row['hamke'];
  echo "&lt;/td&gt;&lt;td&gt;"; 
  echo $row['jaczyk'];
  echo "&lt;/td&gt;&lt;td&gt;"; 
  echo $row['jontow'];
  echo "&lt;/td&gt;&lt;td&gt;"; 
  echo $row['macdonald'];
  echo "&lt;/td&gt;&lt;td&gt;"; 
  echo $row['munozcano'];
  echo "&lt;/td&gt;&lt;td&gt;"; 
  echo $row['shaffer'];
  echo "&lt;/td&gt;&lt;td&gt;"; 
  echo $row['soares'];
  echo "&lt;/td&gt;&lt;td&gt;"; 
  echo $row['wenger'];
  echo "&lt;/td&gt;&lt;/tr&gt;"; 
  } 
  echo "&lt;/table&gt;";
  ?&gt;
  &lt;FORM&gt;
  &lt;INPUT TYPE="BUTTON" VALUE="Return to the Home Page"       ONCLICK="window.location.href='http://localhost/~user/joomla15/custom/skilldisplay.php'"&gt; 
  &lt;/FORM&gt;
