 |
|
Hello, I've created a plugin called {json} that reads JSON data from a file (URL), decodes it and assigns it to a Smarty template variable.
It's also possible to assign only certain branches of nested arrays/objects to template variables which may be useful in cases where a single JSON file is used as some kind of configuration file for an entire project.
JSON objects can be converted to PHP objects or to associative arrays (default), using the obj2obj parameter.
Using the function:
| Code: | | {json file="filename.json" assign="data"} |
assigns the decoded JSON data to $data, converting JSON objects to PHP associative arrays.
| Code: | | {json file="filename.json" assign="data" obj2obj=true} |
does the same, but this time JSON objects arre converted to PHP objects.
If the data passed to $data would have a property called 'languages', it is also be possible to assign only that property to a variable like this:
| Code: | | {json file="filename.json" lang="languages"} |
$lang would now have the same value as $data.languages did in the first example (and $data->languages in the second).
And you can have more of these in one statement: | Code: | | {json file="filename.json" lang="languages" coun="countries"} |
More info and the plugin itself can be found at: http://jlix.net/extensions/smarty/json

|

The {json} plugin is updated to version 1.0.1
Smarty doesn't work with true booleans. It uses the value 1 instead of true. Therefore identical comparison (type checking) is dropped for equality comparison for the debug and obj2obj parameters' values.
This means that as of version 1.0.1 the following example will work the way you might expect:
| Code: | | {json file="filename.json" assign="data" debug=$smarty.get.debug} |
This will print the decoded data in the template if &debug=true is added to the URL.
The plugin can be found at: http://jlix.net/extensions/smarty/json

Hmmm, that's weird.
I just downloaded a copy from my own site to test whether the file could have become corrupt, but it just seems to work as it should.
I tried to reproduce the same output you're getting: "August has days" and without any error messages (I assume). This seems to happen when the JSON object is invalid. So perhaps you've missed a character while copying. The JSON example object on my site is valid. You can validate yours on http://www.jsonlint.com/.
Cheers,
Sander

| FYI, please note that JSON library for PHP works only after php 5.2.0. If you own a server with old php version, happen to read this forum and surprise, why this does not work; upgrade |

That's correct and therefor it is stated on the download page that json_decode() support is a requirement.
json_decode() is part of PHP, version 5.2.0 and up. In older versions the PECL extension can be used.
