![]() ![]() To get the example working this will suffice as order_item. Order_item.php would add the item to cart and just echo whatever message you would like displayed. This runs the php script and loads whatever message it returns into. $('#resultMsg').load('path/to/php/script/order_item.php') And I would agree, but it happens that the generated Javascript needs to use PHP variable and when I try to do so, Javascript thinks that I am giving him a string, as he should. However, assuming your script needs to do some server-side processing such as adding the item to a cart, you may like to check out jQuery's - use jQuery to load the path to the php script which does the processing. I have a PHP program that needs to generate Javascript, nothing original in that you might say. If you just want to echo a message from PHP in a certain place on the page when the user clicks the button, you could do something like this: Order nowĭocument.getElementById('resultMsg').innerHTML('') ![]() Using it via onClick() instead of onLoad()Īn example could be provided in the Sample_Dynamic_Frame.zip for your inspection, but didn't find a means to attach it To be resolved: calling updateContent() with a filename and Notice:- use single quotes in the outer javascript and ONLY double quotes in the dynamic php data.PHP is a server-side scripting language that is executed on the server before the page is. and we drop in/outof PHP as necessary to access the dynamic data No, you cannot include a PHP file directly inside JavaScript code.the javascript to use the dynamic data must be in this same file.the php data MUST contain its own css styling (if content is in a frame).the first thing in that file MUST be the.the webpage to be modified MUST be a phtml or some php file.Now our javascripts can get to the PHP globals like this: $textMsgPHP = returnContent('dummy_frame_data_1.txt') $msg2 = returnContent('dummy_frame_data_0.txt') $msg1 = returnContent('dummy_frame_data.txt') preload the dynamic contents now for use later in the javascript (somewhere) Into globals for later access - like this: Error opening source file :(\n' # $filename!\n" Static files of JavaScript would survive most applications but sometimes the ability to include PHP code inside JavaScript scripts and generate the content of the script files on the fly by PHP is a better option. To the content: **foo.html becomes foo.phtml**Īnd we add to the top of that page. We change the webpage in question into a PHTML type to allow the server side PHP access The form of contents can be accessed through the GET and POST actions in PHP. Golly gee we don't need PHP to do that now do we! But that creates a structure for Method 1: This example uses form element and GET/POST method to pass JavaScript variables to PHP. Then we can alter the display with a simple Y.="#00ee00" // visual confirmation that the updateContent() was effectiveĪssuming we have an html file with the ID="frameContent" somewhere, create a default, simplistic alteration usinga fixed string. Y.="red" // demonstration of failure to alter the display Var frameObj = document.getElementById("frameContent") The objective is to get some dynamic info (say server configuration items) from the server into the Javascript environment so it can be used when needed - typically this implies DHTML modification to the presentation.įirst, to clarify the DHTML usage I'll cite this DHTML example: CLEARLY the two just cant interact.īut - good news it can be made to work and here's how. One final point to note is that when working outside of function bodies, at a global level, let does not create a property on the global object, whereas var does.We all grew up knowing that Javascript ran on the Client Side (ie the browser)Īnd PHP was a server side tool (ie the Server side). Aside from Header and Footer scripts, you can also use WPCode to insert custom PHP code snippets, JavaScript code snippets, CSS code snipets, HTML code. The more recently introduced let keyword allows for more precise and predictable variable scoping, and allows programmers to safely reuse names for temporary variables within the same function. From time to time we are mixing different programming languages in one file. The behavior of var can be useful in some cases, but is quite different from other programming languages, and can cause difficult-to-resolve bugs. Tutorial: Highlighting PHP syntax inside JavaScript Last modified: 11 January 2023 In this tutorial, we'll explore using Template Data Language for working with mixed syntax in PhpStorm. This works because the var declaration of functionVariable is hoisted to the top level of nestedScopeTest() before execution, but the let declaration of blockVariable is not. Console.log(functionVariable) // will print 1Ĭonsole.log(blockVariable) // will print 2Ĭonsole.log(blockVariable) // will throw an error ![]()
