how to get the value of list field type (check boxes) $node=node_load(18);
$logo_img = file_create_url($node-&gt;field_site_logo[$node-&gt;language][0]['uri']); //origional image path
$show_logo = $node-&gt;field_options_site_logo['value']; //original image path
if(isset($logo_img)) {
  $web_logo = theme('image_style', array('path' =&gt; $node-&gt;field_site_logo[$node-&gt;language][0]['uri'], 'style_name' =&gt; 'site_logo'));
  print $web_logo;
}


I created CMS option of uploading site logo. I also added an option of show/hide this logo (form in node 18). Using the above code, I am able to load the image but don't know how to hide it if this option is not selected. I just want to know how to get the value of this check box. I can write the condition to show or hide this. Please help. Also, please let me know how to include alt option to the above image.
Where do you put this PHP code? If it's in the page.tpl.php, then you can use the $logovariable to display the field or not.

Otherwise, this configuration is available in your theme. So you need to get your theme configuration, with theme_get_setting. You should have a variable 'toggle_logo' or something like this. The full code would be

$test = theme_get_setting("toggle_logo");
if($test) {
   //Put your code here
}


If you're using different theme, or you need to get this value for a specific theme, then you need to pass your theme name as second parameter of the function, for example:

$test = theme_get_setting("toggle_logo", "my_custom_theme");


[EDIT FULL ANSWER]

So you just need to check the value of the field field_options_site_logo before outputing the image:

$node=node_load(18);
if(isset($node-&gt;field_options_site_logo['und'][0]['value']) &amp;&amp; $node-&gt;field_options_site_logo['und'][0]['value'] == 'yes') {
  $logo_img = file_create_url($node-&gt;field_site_logo[$node-&gt;language][0]['uri']); //origional image path
  $show_logo = $node-&gt;field_options_site_logo['value']; //original image path
  if(isset($logo_img)) {
    $web_logo = theme('image_style', array('path' =&gt; $node-&gt;field_site_logo[$node-&gt;language][0]['uri'], 'style_name' =&gt; 'site_logo'));
    print $web_logo;
  }
}
