Variables assigned from PHP
Variables assigned from PHP are referenced by preceding them with a dollar ( $ ) sign.
index.tpl source:
This above would output:
Associative arrays
You can also reference associative array variables by specifying the key after a dot "." symbol.
this will output:
Array indexes
You can reference arrays by their index, much like native PHP syntax.
This will output:
Properties of objects assigned from PHP can be referenced by specifying the property name after the -> symbol.

How to parse or decode a JSON object in a Smarty template?
@ consuelo
Smarty is a template engine for PHP, and it doesn't have built-in functionality for parsing JSON objects. However, you can use PHP functions to parse JSON in a Smarty template.
Here's an example of how to parse a JSON object in a Smarty template using the json_decode() function in PHP:
In this example, we first define a JSON string, and then we use the json_decode() function to convert it into a PHP object. We then assign this object to a Smarty variable called json_object .
Finally, we can access the properties of this object using the -> operator in the Smarty template. In this case, we output the name, age, and city properties of the JSON object.
Note that in order to use the {php} tag in Smarty, you need to have the allow_php_tag option enabled in your configuration. This option is disabled by default for security reasons, so use it with caution.

Php – How to display json data in a smarty template
json jsonresult php smarty
I'm using smarty and php for my website. There is some code which converts the data into json. I want to use that data in a smarty template. That data is a set of error messages and I want to display those messages in a assigned smarty template at desired ID. I'm not able to get that in smarty template. Actually what is happening is the error messages are displayed on a plain page instead in the desired tag. Following is my smarty and PHP code: Following is the smarty code where I want to display the error messages:
Now following is my PHP code:
Use JavaScript to parse the JSON, then put the errors in the div.
To make this easier, let's give your div an id :
Alternatively, you could just the pass the message itself from PHP:
This may not be 100% correct, as I don't have your data to test with, but I believe that's right. You get the idea at any rate.

Android – building and running app via gradle and android studio is slower than via eclipse.
I'm sorry, but upgrading development station to SSD and tons of ram has probably a bigger influence than points below combined.
Tools versions
Increasing build performance has major priority for the development teams, so make sure you are using latest Gradle and Android Gradle Plugin .
Configuration File
Create a file named gradle.properties in whatever directory applies:
- /home/<username>/.gradle/ (Linux)
- /Users/<username>/.gradle/ (Mac)
- C:\Users\<username>\.gradle (Windows)
Gradle properties works local if you place them at projectRoot\gradle.properties and globally if you place them at user_home\.gradle\gradle.properties . Properties applied if you run gradle tasks from console or directly from idea:
IDE Settings
It is possible to tweak Gradle-IntelliJ integration from the IDE settings GUI. Enabling "offline work" (check answer from yava below) will disable real network requests on every "sync gradle file".
Native multi-dex
One of the slowest steps of the apk build is converting java bytecode into single dex file. Enabling native multidex (minSdk 21 for debug builds only) will help the tooling to reduce an amount of work (check answer from Aksel Willgert below).
Dependencies
Prefer @aar dependencies over library sub-projects.
Search aar package on mavenCentral , jCenter or use jitpack.io to build any library from github. If you are not editing sources of the dependency library you should not build it every time with your project sources.
Consider to exclude project and cache files from antivirus scanning. This is obviously a trade off with security (don't try this at home!). But if you switch between branches a lot, then antivirus will rescan files before allowing gradle process to use it, which slows build time (in particular AndroidStudio sync project with gradle files and indexing tasks). Measure build time and process CPU with and without antivirus enabled to see if it is related.
Profiling a build
Gradle has built-in support for profiling projects . Different projects are using a different combination of plugins and custom scripts. Using --profile will help to find bottlenecks.
Vba – Check if a string contains another string
Use the Instr function (old version of MSDN doc found here )
will return 15 in pos
If not found it will return 0
If you need to find the comma with an excel formula you can use the =FIND(",";A1) function.
Notice that if you want to use Instr to find the position of a string case-insensitive use the third parameter of Instr and give it the const vbTextCompare (or just 1 for die-hards).
will give you a value of 14.
Note that you have to specify the start position in this case as stated in the specification I linked: The start argument is required if compare is specified.

Basic assigning Let's revisit the example from the basics section. The following script assigns a value to the 'companyName' variable and renders the template: <?php use Smarty\Smarty; $smarty = new Smarty(); $smarty->assign('companyName', 'AC & ME Corp.'); $smarty->display('footer.tpl'); footer.tpl: <small>Copyright {$companyName|escape}</small>
{assign} is used for assigning template variables during the execution of a template . Note Assignment of variables in-template is essentially placing application logic into the presentation that may be better handled in PHP. Use at your own discretion. Note See also the short-form method of assigning template vars. Attributes: Option Flags:
To access {assign} variables from a php script use getTemplateVars (). Here's the template that creates the variable $foo. {assign var="foo" value="Smarty"} {* or *} {$foo="Smarty"} The template variables are only available after/during template execution as in the following script.
void assign ( string varname, mixed var) You can explicitly pass name/value pairs, or associative arrays containing the name/value pairs. Example 13-1. assign()
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.
Properties of objects assigned from PHP can be referenced by specifying the property name after the -> symbol. name: {$person->name}<br /> email: {$person->email}<br /> this will output: name: Zaphod Beeblebrox <br /> email: [email protected] <br />
Variable modifiers can be applied to variables , custom functions or strings. To apply a modifier, specify the value followed by a | (pipe) and the modifier name. A modifier may accept additional parameters that affect its behavior. These parameters follow the modifer name and are separated by a : (colon). Also, all php-functions can be used as ...

In a Smarty template file, you can assign an array to a variable using the assign function. The first parameter is the variable name, and the second parameter is the array. The first parameter is the variable name, and the second parameter is the array.
