Low Events - PHP error on non-date info in url.

Phil Brienesse 20 Apr 2014 19:39 problem, complete

Hi, trying to create an events filter for a given date range using url segments such as

website.com/2014-04-01/2014-05-25

This would display events between April 1 and May 25. This works fine unless someone enters url segments which are not dates for example.

website.com/nothing/nothing

that returns the following error

Message: DateTime::__construct() [datetime.--construct]: Failed to parse time string (nothing) at position 0 (n): The timezone could not be found in the database

Filename: libraries/Low_date.php

Line Number: 448

I have tried using both

{exp:low_events:entries channel="events" date_from="{segment_1}" date_to="{segment_2}" unit="custom" limit="2" show_future_entries="yes" status="open|no_board_display" dynamic_parameters="category" paginate="bottom"}

and

{exp:low_events:entries channel="events" date="{segment_1}; {segment_2}" unit="custom" limit="2" show_future_entries="yes" status="open|no_board_display" dynamic_parameters="category" paginate="bottom"}

Any ideas on how to work around this?

   Right now, the only fix is editing the core file. Open up libraries/Low_date.php and look up line #448, which reads:
   
   

   $date = new DateTime($str);

   
   
   Change that to:
   
   

   try 
    { 
     $date = new DateTime($str); 
    } 
    catch (Exception $x) 
    { 
     $date = new DateTime; 
    }

   
   
   ...which should suppress the error and fall back to today as the date.

   That change causes a 500 internal server error. Running php 5.2.17 if that makes a difference.
   
   I was also considering checking the segments with switchee and a regex to make sure they were valid but I am horrible at regex and trying to come up with something that works.

   Hmm, that code does work in php 5.3, so that's looking like some sort of php issue that I cannot work around.
   
   The regex for the date pattern is this:
   
   

   \d{4}-\d{2}-\d{2}

   
   
   So you could try that with Switchee.

   Or try and use this code as the replacement instead:
   
   

   if ( ! $date = date_create($str)) 
    { 
     $date = date_create('now'); 
    } 
   
    return date_format($date, 'Y-m-d');

   Yes that works. Returns events from today. That will work. I figured out why regex wasn't working for me too has to do with encoding EE's special characters such as | and }. Did alot of research and came up with this for a date regex. Works well.
   
   {case value="#^((20|21)\d\d)-(0?[1-9]|1[012])-(0?[1-9]|[12][0-9]|3[01])$#"}
   
   Thanks for the help didn't expect any resolution on Easter Sunday.
