Ajax :: Pass Variables To Php - Use $POST But It Is Not Working ?
May 4, 2011
how can I make ajax pass variables to php, I been trying to use $POST but it�s not working for me, I have this script
Code JavaScript:
function get_school_data()
{
var xmlhttp;[code]....
What I am trying to achieve is to send the value of country to php and have it stored in a variable so I can then select a different table in the database, but when I do it the way I am, it does not work, as it gives me an undefined variable
Alright, I'm trying to make these variables pass through as a post, but it's not receiving any posts through the other side. When I use the GET method though, it picks it up.
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.
Now i have a doubt, how i can pass the variables $var and $var1 with ajax to a PHP file? to make sql querys and replace the values of $var and $var1[code]...
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 have acollection of local variables populated via Flash movies and scripts, and now I need to submit an ajax post (can also be get, but prefer post). I have tried:
The problem with this is the encoding of the localParam1 and localParam2 sometimes breaks the normal & delimeters. An even more problem is I sometimes haveupwards of 25+ local variables that I need to submit. These inline +s makes it feel, and look, like one huge hack - not to mention the encoding. One last restriction: I cannot use any jquery plugins due to the company's policy. So, I'm looking for something small and light as a solution - not a plug-in. Isn't there an easy way to do this? ONe thought I had was to create a new <form> on the page, and insert the variables as new <input /> fields - and then finally submit the entire form. Again, a big hack + css
IE does not seem to make the post using the following code:
$(function(){ $("#update").click(function(ev) { var target = $(ev.target); if (!target.hasClass("add_btn")) { return false ; } var li = target.parents("li"); var _title = li.attr("data-title");
I am building a web app that uses alot a jquery including a function that reaches out to a webservice using $.ajax to grab data and return to tdata to the web app. The function that makes the call is outside the ready block but is called in the ready block to make it run on the load. After the load I use a timer to keep calling the function to keep things up to date. But after the first run the function does not seam to work. This might sound wierd, but the ajax function appears to run after the initial go, but it always returns the original request, it does not make new request to the server. I use fiddler and watch what going on and after the initial run method it doesnt make any other calls even though I see the ajax method being stepped through using debugging software and see the AJAX call being attempted and returned successfully.
var REQUESTURL = '/citizenQuestionWCF.svc/'; var prOptions = ''; $(document).ready(function () { getQuestions();
When i override the ajax method with $.ajaxSetup and set the type:'post', then consecutive calls to fetch data from the server, by Ajax Tabs (url), the tab stays Loading... forever. Firebug shows that a POST request was made and it completed successfully, however, the Tab stays Loading... forever. If i set it back to type:'get', the Tabs work fine. is it a bug, restriction? if it's a restriction, then why? workarounds?
Heres the code for sub-account-ajax.php: <?php if (isset($_POST['email_address'])){ echo 'youre set'; }else{ echo 'nothing set'; }?>
When this code is executed I do not get any alerts or any error messages whatsoever. I've been pretty good with figuring things out so far with jQuery, but this is the first I'm stumped with.
I have something that runs on a server with no PHP or any of those widgets.
A user submits a form with 6 fields. Clicks "Go". A page appears that displays what he just entered, with a form of his data in hidden fields, and a link with document.form.submit() that takes you to a CGI program. It must be 2 different page loads.
Is displaying what he entered in the form in the next page possible with JavaScript? If so, what are the JS variables that would let me access that data?
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 have a div on my page that is populated by a php calendar. The calendar also has month and year input fields so that the user can browse to different months. I would like to create a jquery function so that, when a user changes the month or year field, the div reloads the calendar and passes the selected month and year variable back to the php script. Here is what I have on my page:
<head> <script type="text/javascript"> function startCalendar(month, year) {
There are different ways by which values of variables can be passed between forms. One of the ways is to use the setTimeout to pass the values or data. Here the biggest advantage is we can pass data to a different site even running automatically.I would need from someone a bit of help to pass the variable links from form1 to variable strLink in form2 using SetTimeout.We have the following schema:An options select menu where value of the option, sent with a submitted form, is specified with the value attribute. In the absence of a VALUE attribute, the value is the content of the option element.
How can I send POST variables to a new window on form submit. I tried the below but what happens is the new window "foo.php" opens but no POST variables are present and also the parent page refreshes when I want it to remain static. Code:
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.
