I am getting a Notice in a wordpress theme, but i think its a general PHP warning.
Notice: Undefined index: saved in ..\functions.php on line 255
The line 255 reads as:
if ( $_REQUEST['saved'] ) echo '<div id="message" class="updated fade"><p><strong>'.$themename.' settings saved.</strong></p></div>';
Any suggestion, how i can fix it?
Thanks.
Change to:
if(isset($_REQUEST['saved']))
You should consider using a method specific super-array like $_GET or $_POST instead of the more general $_REQUEST array.
if ( isset($_REQUEST['saved']) && $_REQUEST['saved'] ) ...
Yes, this is a general php notice. You should use "empty" function like this:
<?php
if (!empty($_REQUEST['saved']))
echo '<div id="message" class="updated fade"><p><strong>'
. $themename
. ' settings saved.</strong></p></div>';
This function will save you from "false", "0" and other "empty" values.
You can also check if a variable is set using isset(). Not sure if this applies to your specific situation.
if ( isset($_REQUEST['saved']) ) {
echo '<div id="message" class="updated fade"><p><strong>'.$themename.' settings saved.</strong></p></div>';
}
