 Posted: Sat Dec 19, 2009 1:59 pm Post subject: Apache crash on custom plugin |
 |
|
Hello all,
In smarty 2 this used to work:
| Code: |
Function Smarty_Function_Header($Params, &$Template)
{
Return $Template->Fetch(header.tpl');
}
|
Now I have transformed this to Smarty 3:
| Code: |
Function Smarty_Function_Header($Params, $Smarty, $Template)
{
Return $Template->Fetch('header.tpl');
}
|
But now Apache crashes with the error:
| Code: | | Parent: child process exited with status 255 -- Restarting. |
That usually means an infinte loop somewhere.
Am I doing something wrong in the new version?
Thanks |

No nothing, just crash.
But I tried this (stupid that I didn't try that before)
| Code: |
Function Smarty_Function_Header($Params, $Template)
{
Return $Template->Fetch('header.tpl');
}
|
So the signature has changed only from &$Template to $Template, and that works.
I don't know why the Smarty plugins use:
| Code: |
function smarty_function_html_image($params, $smarty, $template)
{
|

In Smarty 3 the template object is passed as third parameter. You did call the fetch methode on the wrong object.
Wrong:
| Code: | Function Smarty_Function_Header($Params, $Smarty, $Template)
{
Return $Template->Fetch('header.tpl');
} |
Right:
| Code: | Function Smarty_Function_Header($Params, $Smarty, $Template)
{
Return $Smarty->Fetch('header.tpl');
} |
The template object does have also a fetch methode which was called in wrong context and did indead result in an endless loop.
Another note:
Why do you not use {include file='header.tpl'} but a fuction plugin?
You will lose some of Smarty's features like compile checking of subtemplates for cached pages and other when loading subtemplates by plugins. |

Because this is a stripped down version, I add different kind of things like checking if somebody is loggedin, but also adding javascript and CSS files etc.
But what is the 3rd param used for? |

| There are plugins thinkable which may need access to the properties and methodes of the template objects because of the new structure of Smarty 3. |
