'selected' : '' ?> value="true">                         <?php echo $lang['enabled']; ?>                     </option>                     <option <?php echo ($customoptions == true) ? 'selected' : '' ?> value="false">                         <?php echo $lang['disabled']; ?>                     </option>                 </select>             </td>         </tr>         <?php         if ($customoptions)         {             ?>             <tr>                 <td>primary color</td>                 <td><input name="primarycolor" type="text" id="primarycolor" value="<?php echo $primarycolor; ?>"></td>             </tr>             <tr>                 <td>background color</td>                 <td><input name="adminbg" type="text" id="adminbg" value="<?php echo $adminbg; ?>"></td>             </tr>             <?php         }         ?>     </table>     <input type="submit" name="submit" value="<?php echo $lang['ok']; ?>"> </form>

ps: know isn't way save settings in php file test, never go live.

ok, try has top says if (isset($_post['submit'])) try , give default value if isn't set. if (!(isset($_post['submit']))) i'm referrin $customoptions variable $primarycolor , $adminbg

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
