 Posted: Tue Jun 10, 2003 4:03 pm Post subject: insert tag |
 |
|
Hello All,
Not really new to smarty, as an user, but now trying to go further, I have a pb with the insert tag. I looked everywhere to find something but ...
In the documentation, I noticed I can call a function with an insert tag
For instance:
<img src={insert name="getImage" image=#$urlimage#}>
$urlimage had been defined above, with a $smarty->assign("urlimage", "urlimage");
Does not work, it seems $urlimage is already in the cache.
I noticed in the documentation, I can "pass $smarty in my function as a second parameters", I dont see how !
Some help ?
Thanks

Hi mozaia:
It looks like your syntax is a little bit off:
| Quote: | | <img src={insert name="getImage" image=#$urlimage#}> |
#$urlimage# ?? Does that work? It LOOKS like you are trying to dynamically select a configuration field value, though I never tried that myself. Are you really trying to do this:
<img src={insert name="getImage" image=$urlimage}> ??

I assume you mean in the API. Smarty provides prototypes for PHP functions that you can register allowing you to customize how Smarty works. Most of the functions accept &$Smarty as a parameter, allowing for a lot of flexibility in your custom functions. Do you have an example of what you are trying to do?

Hi boots,
Ok, I understand, #var# is only from var coming from configuration files. Yes, I am trying to use the second image=$urlimage
So I correct it in my script, but I still have pb.
I am trying to use the cache system, with a dynamic part in my page. That $urlimage is coming for a php above. It seems like, eventhough insert tag is done for that, that the variable $urlimage is a part of the cache, so, when it is modified, the cache does not consider it. If I use #urlimage#, it works like it should.

That is what I look for, and I dont understand how I pass it to the function. Anyway I notice I can use a "global $Smarty;" in my function, the I have access to it.
In fact, I am just trying to study smarty, I have a new development to do, and I want do use: smarty, xhtml and css files, a kind of training 
Thanks for the help. |

hello,
1. if you want to access a config-var dynamically you can do {$smarty.config.$urlimage} or in your case {insert name="getImage" image=$smarty.config.$urlimage}
(see: http://smarty.php.net/manual/en/language.variables.smarty.config.php )
2. your assumption is correct: the parameters to insert a cached, so that insert always receives the same on each call.
3. if you want to use template-vars dynamically inside an insert function you can do sth. like:
| Code: |
function smarty_insert_getImage($params, &$smarty) {
$image = $smarty->get_template_vars('urlimage');
/* $image is the currently assinged $urlimage now, not the one it was when the cached template was generated */
}
|
(see: http://smarty.php.net/manual/en/api.get.template.vars.php )
just a few $0.02 from me  |

Ok then I'm going to check with the configuration files.
