[MODx] 8. Snippet get data, chunk display

Simple Example:

Lets process this chunk and output its value. We have this Chunk, called "Welcomechunk":

< P > Welcome [[+name]]! </ P >

We ' ll put this on our Snippet:

$output $modx->getchunk (' Welcomechunk ',array(   ' name ' = ' John ',)); return $output;

So every key in the associative array passed to the getChunk method corresponds to an available placeholder Insid e the chunk, e.g. [[+name]

< P > Welcome john! </ P >

Nested $properties

In our Chunk:

<href= "http://site.com/profile?user_id=[[+user.id]]!" > User Details</a>

In our Snippet:

$output $modx->getchunk (' Userlink ',   Array (' id ' = + 123);  return $output;

parsing a String

Sometimes you need to parse a string using the MODX parser–this does isn't use GetChunk, but it's related. Using the MODX parser is a bit slower than using a simple str_replace function, but it does let's use complex Placeholde RS (e.g to include another Chunk) and output filters etc. The trick is to create a temporary Chunk object and then run the process method on it.

//The formatting String$TPL= ' Hello, my name is [[[+name]] '; //Properties$props=Array(' name ' = ' Bob '); //Create the temporary chunk$uniqid=uniqid();$chunk=$modx->newobject (' Modchunk ',Array(' name ' = ' = ' {tmp}-{$uniqid}"));$chunk->setcacheable (false); $output=$chunk->process ($props,$TPL);
