This lib has moved to become part of the larger BlueUtils and is not being maintained. It will be removed soon.

Super-Simple framework for making AJAX easier to deal with on the PHP side. It also includes some JS objects for communicating with an AJAX php script built using this lib.

##Getting Started

We recommend you install the package with Composer:

composer require bluepost/blueajax

Alternatively you can download the Latest Release, unzip it, and upload the src folder to your environment. Then require it for every file for which you need it.

require_once ('BlueAjax.php');

The javascript components are all in JS/BlueAjax.js file.

• Make all AjaxResponse functions use respond()

The framework is set up to use "success" and "error" to communicate data. Both the php and js sides rely on this. The data is a string, so we recommend that you use them to communicate the status of the request. This allows for human readable response messages without an unnecessary booleans being passed back and forth.

    <?php
    require_once '../BlueAjax.php';
    //Create a response object
    $response = new BluePost\AjaxResponse();
    //Check if the GET index "q" isset, if not, die with an error: '{"error":"q not set"}'
    $response->assert(GETisset("q"), error("q not set"));
    //Check if $_GET["q"] is a correct value (1 or 2), if not die with an error: '{"error":"q invalid"}'
    $response->isGoodVal($_GET["q"], [1,2], error("q invalid"));
    //If $_GET["q"] is 1, then make sure that the GET index "text" is set. If not, die with an error: '{"error":"text not set"}'
    $response->condAssert($_GET["q"] == 1, GETisset("text"), error("text not set"));
    //Respond with an "All good!" message
    $response->respond(success("All good!"));

    <script src = "https://code.jquery.com/jquery-2.2.1.min.js"></script>
    <script src = "/JS/BlueAjax.js"></script>
    <script>
        var req = new GetAjaxRequest ("/src/tests/test.php", {"q": 1, "text":"Text here"})
                .onError(function (f) {console.log(f)})
                .onSuccess(function (s) {console.log(s)})
                .execute()
        
        var AjaxRequest = AjaxRequestFactoryFactory("/src/tests/", 
                //OnError
                function (f) {console.log(f)},
                //OnSuccess
                function (s) {console.log(s)}
            );
        var req = AjaxRequest("test.php", {"q": 1, "text":"Text here"}).execute()
    </script>

• __construct($baseArray = Array())
  • The constructor function takes an optional $baseArray which will form the inner response object (see respond, addResponse)
• assert($test, $error, $json = TRUE)
  • If $test is FALSE then the function will die with $error. If $json is TRUE, then the function will json_encode $error.
• isGoodVal($needle, $haystack, $error, $json = TRUE)
  • If $needle isn't in $haystack the function will die with $error. If $json is TRUE, then the function will json_encode $error.
• isGoodKey($needle, $haystack, $error, $json = TRUE)
  • If $needle isn't a valid key for the array $haystack the function will die with $error. If $json is TRUE, then the function will json_encode $error.
• condAssert($cond, $test, $error, $json = TRUE)
  • If $cond is true then the function will call assert($test, $error, $json).
• addResponse($key, $value)
  • This will add the key-value pair to the inner response object which is used when the respond function is called.
• respond($response=Array(), $add=TRUE)
  • This will die with the json_encoded value of $response merged with the inner response array (see addResponse). If $add is False then the inner array won't be used.

• GETisset($index, $harsh = TRUE)
  • This function will return TRUE if $_GET[$index] isset. If $harsh is TRUE then the function will use strictIsset
• POSTisset($index, $harsh = TRUE)
  • See GETisset but with $_POST
• strictIsset($test, $notZero = FALSE, $notEmptyString = TRUE, $notNull = TRUE)
  • An isset that has a number of extra tests, controlled by the boolean variables
• laxIsset ($test, $NES = FALSE)
  • This uses strictIsset with all optional params set to FALSE, except $notEmptyString, which is set to $NES
