This tweak will change the “All Posts” page in the administration section of a WordPress site.
It adds the ability to filter the post list based on a custom field that has been used in any of the posts at any time. Continue reading “WordPress tweak to manage posts admin, filter and show custom field”
If you have a function that takes an optional parameter – e.g.
function blah($xx,$yy='Default',$zz){ ....
You can use the function and ensure that the optional parm always takes the correct default (even if the definition changes) by passing a “NULL” to it. e.g.
... $mydate=blah($something,NULL,$more); ...
# Handle web parms (Call as: myParms('report');)
# Ensures that the given parm is always set
function myParms($var) {
global $$var;
if(isset($_REQUEST[$var])){
$$var=$_REQUEST[$var];
} else {
$$var='';
}
}
