 |
|
Hello,
I have a variabel {$getRow.date} (comes from a foreach loop) who contains a mysql datestamp and a second variable {$getRow.time} who contrains a string (example: 11 [min.]).
How can i now subract '11 minutes' from the first variable and get the new timestamp that i can formate with date_format?
PS. Sorry for my bad english i hope you understand me 
Thanks in advance. |

You can try:
| Code: | | {"`$getRow.date` -`$getRow.time`"|strtotime|date_format:"%c"} |
You will need to make sure the 'time' string is understandable to PHP.
I think "11 [min]" is not understandable, but "11 minutes" is understandable.
Everything starts as a string, but embedded Smarty variables are escaped with backticks. |

Hello,
Thanks for you reply.
$getRow.time CONTAINS ONLY a number = 11
Maybe somthing like that is possible?:
| Code: | | {"`$getRow.date` -`$getRow.time` minutes"|strtotime|date_format:"%c"} |
I will give it a try this evening or tomorrow. |

Write a wrapper function that uses DateTime and DateInterval classes to manipulate times.

It is possible, but very dirty and prone to failures.. |

Hi,
After some testings i think i have found a better way to do this with math function:
| Code: | | {math equation="a - (60 * b)" a=$getRow.date|strtotime b="10" assign="finalTime"}{$finalTime|date_format:"%H:%M"} |
Here i get the correct results of that row -10 minutes.
What do you think about?
EDIT: After do the script all works like a charm |

| I already said what I think about it. Dirty hack built on presumptions. |
