 Posted: Tue Apr 11, 2017 10:34 am Post subject: function "substr" |
 |
|
Hello,
I encountered a problem with the "substr:" function.
I want to use this function to delete the last character of the string.
Here is how I write my variable:
| Code: | {capture assign="loop_moderators"}
{foreach name=moderators from = $session.programme_moderators item=moderator}
{$moderateur.formatage_programme},
{/foreach}
{/capture}
{$loop_moderators|substr:0:-1}
|
When I test, the last character is not deleted ??
Would you see why it does not work?
Thank you for your help |

{$loop_moderators|bin2hex}
{$loop_moderators|substr:0:-1|bin2hex} |

"It doesn't work" is a ridiculous statement. It conveys essentially no information.
Please state clearly, what you are doing, what results you expect, and what you actually observe. |

Ok sorry for that answer!
Here are more details:
Currently the result of this variable "{$ loop_moderators | substr: 0: -1}" is:
| Quote: | | P. Coulom (Toulouse / FRANCE), C. Silvain (Poitiers / FRANCE), P. Seksik (Paris / FRANCE) |
The last character is not deleted because the last character is the "comma"
With your variable "{$ loop_moderators | bin2hex}" or "{$ loop_moderators | substr: 0: -1 | bin2hex}" here is the result:
| Quote: | {$ Loop_moderators | bin2hex}
...292c0a090909090909090909
|
| Quote: | {$loop_moderators|substr:0:-1|bin2hex}
...292c0a0909090909090909 |
To recall here is the loop that I use to display the data of my variable
| Code: | {capture assign="loop_moderators"}
{foreach name=moderators from = $session.programme_moderators item=moderators}
{$moderateur.formatage_programme},
{/foreach}
{/capture} |
Thanks |

Sooo... evidently, the code works as intended. It properly strips the last character off the provided string.
Your problem is that your source data is full of whitespaces. Either provide a clean source data, or change code logic to remove unnecessary whitespaces. |
