AJAX :: Pass PHP Multiple Variables?
Oct 19, 2010
I've recently begun using AJAX on my website and have ran into a problem.My webpage: catalogue.php contains a category variable named $cid which the page GETS in order to display products from the correct category. This works fine.I now want to implement a drop-down box to sort by price, name, newest etc...I have tested the AJAX out with a dropdown box for changing the category and it works fine, this is because it is only passing one variable which it gets via the javascript "this.value".
The sort by price box requires two variables to be passed .I can pass the "this.value" which tells the javascript function I want to sort by price/newest/etc but I cannot figure out how to pass the category variable ($cid) so that when the xmlhttp.open calls the url: getSort.php it passes both pieces of info.My javascript is:
Code:
function showSort(str)
{
var cat = <?php echo $cid ?>;[code].....

I'm using AJAX to, on the click of a button, run a PHP script that dynamically generates a new line of text, and passes that to the script.The PHP script, new_sentence.php, just echos out the sentence.This works fine.But what I would like to do is for the PHP script to dynamically change JavaScript variables.how to pass multiple variables from PHP to JS.I can, of course, pass one by having the PHP script echo anything, and then use JS to set the variable to the PHP output. But what if I wanted to set two or three JavaScript variables at once?Here's my code in the HTML page that contacts new_sentence.php:
Code:
function ajaxRefresh(){
var ajaxRefresh;
ajaxRequest = new XMLHttpRequest();[code].....
When I press the "Refresh" button on the HTML page, it runs the ajaxRefresh function, which calls new_sentence.php. Then, once it gets the response, it changes the text of the element named "div" to whatever text the new_sentence.php echos.I'd like to figure out how to get a couple of variables.I would imagine this is simple. how to set the variables in PHP and then how to retrieve them in JS.

I have multiple triggers and I am trying to pass variables via a "rel=" tag (which are unique id's) for each trigger I can get most of it working, problem is that since there are multiple triggers with id="newsTrigger" only the first listed trigger works Using PHP/mySQL. An example trigger is:
while loop{
echo '<span id="newsTrigger" style="font-size:0.8em;" rel="'.
$rowNewsid[$counter].'"><a href="'.$rowNewsPermalink
[$counter].'">'.substr($rowNewsHeadline[$counter],0,40).'</a></span>';
}
The above outputs a large number of rows with the same span id of "newsTrigger". When a user mousesover any of the newsTrigges I am trying to get an ajax dialog to load up content based on the id that is being passed through the rel tag. How do I do this? The javascript so far is:
<script>
$(document).ready(function(){
$("#newsTrigger").mouseover(function() {
var newsid = $(this).attr("rel");
[Code].....

I have used AJAX lots before and I wondered if it was possible to set variables from an AJAX file E.g. an ajax file could set
var set1 = 10;
var set2 = 55;
with both variables coming from an external file called by AJAX. Which JS side perform the request and the format of the file that is requested.

I'm sure there is a really, really simple way to solve this issue. I'm just not a programmer so I don't know it off the top of my head. I have this script ext.php that accepts a variable ref.[URL]..The problem is that there is also a '?' in the variable ref that I'm using. Like so:[URL]...I suspect because there is another '?' in variable ref, ext.php has a problem with it. I cannot change ext.php or sitename.asp.
So my question is, how can I make this work properly via the url? I've tried using %26 for the '?' as well as the & html escape code, but it still doesn't work.

I am new to Javascript and have searched the forums and can't seem to find the missing link. I have 3 radio groups, each button has a $ value, and I merely want to display the amounts that are selected from each group. I have the page up that you can view it to get a better idea code...
When I press the submit button I want it to tell me if a button has been pushed in a certain group the amount that was selected. When I press the button now nothing happens.
Looking at the preview I have used the [CODE] tags but it appears it is only allowing it on one continuous line. Please tell me how to fix that and I can change it before someone trys to debug the code.

function get_states(country_element,state_element){
countryElementIDHash = "#" + country_element;
stateElementIDHash = "#" + state_element;
$(stateElementIDHash).empty();
var geonameId = $(countryElementIDHash).val();
$.getJSON("[URL]",
{ 'geonameId': geonameId },
function(data) {
if (data.geonames == null) alert('No regions');
$.each(data.geonames, function(i,item){
$(stateElementIDHash).append($('<option>' + item.name + '</option>'));
});
});
}
I'm writing a function to populate a SELECT based on the select value of another SELECT. I can't figure out why this isn't working. It has something to do with not having "'s in my $(). for example: If this function wasn't dynamic.
The code:
$(countryElementIDHash).val(); could simply be
$("#country option:selected").val();
How can I pass dynamically assigned names into a $() ?
