I have image url in js variable /w/s/wsh10-black_main.jpg.
Question: How can I get media cache url in js, like: https://mydomain.test/media/catalog/product/cache/c687aa7517cf01e65c009f6943c2b1e9/?
As result I want get full url, like https://mydomain.test/media/catalog/product/cache/c687aa7517cf01e65c009f6943c2b1e9/w/s/wsh10-black_main.jpg
You need to get base url in order to have the complete url you want. You can do this by defining a function that returns base url so,
<?php $baseUrl = $this->getBaseUrl() ; ?>
<script type="text/javascript">
function getBaseUrl() { return '<?php echo $baseUrl; ?>'; }
</script>
then use it in JavaScript:
var urrl = 'http://'+getBaseUrl()+'/w/s/wsh10-black_main.jpg';
You can also refer to this link

Hope it helps!

Face problem when writing PHP syntax in javascript syntax.
var id = $("#data-1").val();
var url = '<?= base_url('home/alone/'); ?>.'id'';
console.log(url);
I need to place the id at the end of url. But my code is not working. What is wrong?
Thank you in advance.
use " instead of ' like this:
var id = $("#data-1").val();
var url = "<?= base_url('home/alone/'); ?>" + id;
console.log(url)
I'm navigating through the site by doing this
$('.account-nav a').on('click', function (e) {
e.preventDefault(e);
var url = this.href;
console.log(url);
$('.account-nav a> .account-tab-current').removeClass('account-tab-current');
$(this).children('.account-tab').addClass('account-tab-current');
$('#user-page-content').remove();
$('#user-page-container').load(url + ' #user-page-content').hide().fadeIn('fast');
var url = $(this).attr('href');
if (url != window.location){
window.history.pushState({path: url}, '', url);
}
Problem is, one of the pages contains a script that doesn't get loaded. that page. I also pass in a php variable. It looks something like this:
<div id ='user-page-container>
<div id ='user-page-content>
//content with $variable
<script>
var myVariable =
'<?php
if (isset($variable)) {
echo $variable;
}
//some jquery animation stuff here
?>';
</script>
</div>
</div>
Nothing inside the script get loaded when the html is loaded through jquery.
I'm trying to retrieve multiple $_GET variables within PHP. Javascript is sending the URL and it seems to have an issue with the '&' between variables.
One variable works:
//JAVASCRIPT
var price = "http://<site>/realtime/bittrex-realtime.php?symbol=LTC";
//THE PHP END
$coinSymbol = $_GET['symbol'];
echo $coinSymbol
OUTPUT: LTC
With two variables:
//JAVASCRIPT
var price = "http://<site>/realtime/bittrex-realtime.php?type=price&symbol=LTC";
//THE PHP END
$coinSymbol = $_GET['symbol'];
$type = $_GET['type'];
echo $coinSymbol
echo $type
OUTPUT: price
It just seems to ignore everything after the '&'. I know that the PHP end works fine because if I manually type the address into the browser, it prints both variables.
http://<site>/realtime/bittrex-realtime.php?type=price&symbol=LTC
OUTPUT ON THE PAGE
priceLTC
Any ideas? It's driving me nuts - Thanks
UPDATE - JAVASCRIPT CODE
jQuery(document).ready(function() {
refresh();
jQuery('#bittrex-price').load(price);
});
function refresh() {
setTimeout( function() {
//document.write(mintpalUrl);
jQuery('#bittrex-price').fadeOut('slow').load(price).fadeIn('slow');
refresh();
}, 30000);
}
Separate the url and the data that you will be sending
var price = "http://<site>/realtime/bittrex-realtime.php";
function refresh() {
var params = {type:'price', symbol: 'LTC'};
setTimeout( function() {
//document.write(mintpalUrl);
jQuery('#bittrex-price').fadeOut('slow').load(price, params).fadeIn('slow');
refresh();
}, 30000);
}
And in your PHP use $_POST or you can do it like this
$coinSymbol = isset($_POST['symbol']) ? $_POST['symbol'] : $_GET['symbol'];

The following code is supposed to make an array from pictures found in a directory that end in .png using php, then allow buttons to change the pointer on the array and allow the page to display the current picture that the pointer is on. This doesnt seem to be working at all. Am I doing this correctly?
<!DOCTYPE HTML>
<html>
<head>
<style type="text/css">
img {float:left; }
</style>
</head>
<body>
<?PHP
$pages = array ();
$dirname = "assets/pictures/";
$images = glob($dirname."*.png");
foreach($images as $image) {
$pages[] = $image;
}
?>
<?PHP
echo '<img src="'.current($pages).'" class="photo"/>';
function shownext() {
$mode = next($pages);
}
function showprev() {
$mode = prev($pages);
}
function showfirst() {
$mode = reset($pages);
}
function showlast() {
$mode = end($pages);
}
?>
first
previous
next
last
</body>
</html>
onclick will allow you to call a javascript function, while your showprev...showlast functions are all php functions. They are not available in javascript's scope.
Also, in your php code:
You are closing the loop right after $pages[] = $image, I think you intend to display (print/echo) all images.
You don't need a loop to copy $pages to $images. You can easily copy it: $pages = $images.
You should be aware that current only makes sense inside a loop and you are calling it after loop is closed.
I think though, that you are confusing server-side (i.e. php) and client-side (i.e. javascript) execution environments.
onclick , uses to trigger javascript functions.
You cant directly put your php functions on onclick="" events. Alternatively, if you want to use jQuery, you could use $.ajax to request the values on PHP. From there, after you got the image paths, manipulate the next, prev, first, last on the client side. Consider this example:
<?php
if(isset($_POST['getimages'])) {
$dirname = "assets/pictures/";
$images = glob($dirname."*.png");
// collect the images
foreach($images as $image) {
$pages[] = $image;
}
echo json_encode($pages);
exit;
}
?>
<img src="" alt="" id="images" width="200" height="200" />

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
var current_pointer = 0;
var images = [];
$.ajax({
url: 'index.php', // call the php file that will process it, i just used this in the same page
type: 'POST',
dataType: 'JSON',
data: {getimages: true},
success: function(response) {
// after a successful response from PHP
// use that data and create your own array in javascript
images = response;
$('#images').attr('src', images[current_pointer]);
}
});
// simple pointer to navigate the array you got from PHP
$('a.navigate').on('click', function(){
var current_val = $(this).attr('id');
switch(current_val) {
case 'first':
current_pointer = 0;
break;
case 'last':
current_pointer = images.length-1;
break;
case 'next':
current_pointer = (current_pointer >= images.length-1) ? images.length-1 : current_pointer+1;
break;
case 'previous':
current_pointer = (current_pointer < 0) ? 0 : current_pointer-1;
break;
}
$('#images').attr('src', images[current_pointer]);
});
});
</script>
The problem is echo '<img src="'.current($pages).'" class="photo"/>';
This will get echoed once, no matter howoften you change $pages afterwards. You also can't call PHP functions with JavaScript's onclick.
PHP will generate the page on server side! On a fully laoded page, most interaction with the user is done via JavaScript.
To achieve your desired result, you have to export the array to JavaScript and change the image src via JavaScript, a little research will help you.
Stuck on a jquery/javascript function that is attempting to .load a set PHP script but passing get variable parameters. As an aside this is set to happen automatically after 5 seconds. New to posting here but have read a lot of posts and can't seem to find exactly what I am doing wrong.
This function works:
function LoadMyPhpScript()
{
$('#MyDiv').load('hello.php');
}
setTimeout(LoadMyPhpScript,5000);
This function does not work:
function LoadMyPhpScript2(cPhpParamString)
{
var strURL = 'hello.php';
strURL = strURL + cPhpParamString;
$('#MyDiv2').load(strURL);
}
setTimeout(LoadMyPhpScript2('?MyVar1=0&MyVar2=1'),5000);
Here's the hello.php
<?php
echo '<p>Hello, I am loaded with get values of MyVar1=' . $_GET['MyVar1'] . ', MyVar2=' . $_GET['MyVar2'] . '</p>';
?>
Note: this is just a mock-up, would use regex to validate gets, etc in production.
RESOLVED
Here is what I ended up with, thank you!
function LoadMyPhpScript1(cPhpParamString)
{
$('#MyDiv1').load('hello.php'+cPhpParamString);
}
setTimeout(function() { LoadMyPhpScript1('?MyVar1=0&MyVar2=1'); },5000);
When you do this:
LoadMyPhpScript2('?MyVar1=0&MyVar2=1')
You are executing the function and passing the result to setTimeout
Try this:
setTimeout(function() { LoadMyPhpScript2('?MyVar1=0&MyVar2=1'); },5000);
However, sending the url querystring like that is an odd way of doing it. Something like this might be better:
function LoadMyPhpScript2(myVar1, myVar2)
{
var strURL = 'hello.php';
$('#MyDiv2').load(strURL, { myVar1: myVar1, myVar2: myVar2 });
}
setTimeout(function() { LoadMyPhpScript2(0, 1); },5000);
Better try this way:
File help3.html:
<html>
<head>
<script type='text/javascript' src='http://code.jquery.com/jquery-1.8.3.js'></script>
<script type='text/javascript'>
function LoadMyPhpScript2(cPhpParamString)
{
var strURL = 'help3.php';
strURL = strURL + cPhpParamString;
$.ajax({
url: strURL
}).done(function(data) { // data what is sent back by the php page
$('#MyDiv').html(data); // display data
});
}
setTimeout(LoadMyPhpScript2('?MyVar1=0&MyVar2=1'),5000);
</script>
</head>
<body>
<div id="MyDiv">
</div>
</body>
</html>
File help3.php:
<?php
echo '<p>Hello, I am loaded with get values of MyVar1=' . $_GET['MyVar1'] . ', MyVar2=' . $_GET['MyVar2'] . '</p>';
?>
Test on my localhost, and both files on the same folder.
