Smarty local Shutdown cache configuration _php Tutorial

There are several ways to invalidate the cache in some areas (only for the desired cache):

First,Inser:

Defines a handler function to be used for a inser tag, with the format of the function name: insert_xx (array $params, Object & $smarty) where xx is the name of the insert, that is, if you define a function as Insert_ ABC, the method used in the template is {insert Name=abc}

Parameters passed through $params

can also be made into insert plug-in, file name named: insert.xx.php, Function named: Smarty_insert_aa ($params,& $smarty), xx definition ibid.

Second,Register_block:

Defines a block:smarty_block_name ($params, $content, & $smarty) {return $content;}//name represents the domain name of the zone

Register BLOCK: $smarty->register_block (Name, Smarty_block_name, false); The third parameter, False, indicates that the zone is not cached

Template notation: {name} content {/name}

Written as Block plugin:

(1) Define a plug-in function: block.cacheless.php, placed in the Smarty plugins directory

The contents of block.cacheless.php are as follows:

function smarty_block_cacheless ($param, $content, & $smarty) {

return $content;

}

?>

(2) Writing programs and templates

Example program: testcacheless.php

Include (Smarty.class.php);

$smarty = new Smarty;

$smarty->caching=true;

$smarty->cache_lifetime = 6;

$smarty->display (CACHE.TPL);

?>

Template used: CACHE.TPL

Already cached: {$smarty. Now}

{cacheless}

Not cached: {$smarty. Now}

{/cacheless}

Run it now and find that it's not working, and both lines are cached.

(3) Rewrite Smarty_Compiler.class.php (Note: This file is important, please back up first to restore if necessary)

Find $this->_plugins[block][$tag _command] = Array ($plugin _func, NULL, NULL, NULL, TRUE); //My Line in 705

Modified to:

if ($tag _command = = cacheless) $this->_plugins[block][$tag _command] = Array ($plugin _func, NULL, NULL, NULL, FALSE);

else $this->_plugins[block][$tag _command] = Array ($plugin _func, NULL, NULL, NULL, TRUE);

You can also directly change the last parameter of the original sentence to false, I do not understand the internal mechanism of smarty, so add a judgment, as long as the block is cacheless not cache

(4) OK, now clear the Template_c in the compilation file, re-run, it worked?
