Ajax :: Adding Record To Database

Jul 26, 2011

I'm trying to add a single test record (a comment item) to my MySQL database.The double f:ajax tags in commandLink body are to solve a problem, where I had to double click the button to reload content div.And now here comes similar problem:After loading the page, the first click of comment adding button never works - nothing happens. I was adding some logging methods into the addComment method and it is not executed at all on first click. I suspect it's caused by my Ajax reloaded div code, because when I launch such button on a plain page, it works good.Alternatively are there other ways of realizing panel refreshing instead of using ui:include tag, which might be causing the problem here?

Drop Down To Pull Record From Database

Apr 1, 2011

I am trying to create a form to edit existing data in my database. I have 2 drop down boxes( category then item) they do not work correctly. I am using php to populate the drop down boxes but there is nothing dynamic about doing this. I think I need to totally rewrite the page using java script or Ajax but I don't know what parts.So I want the user to select a category from a drop down list populated by database then have it populate the item list(so I think both of these need to be java script in case they change the category it will re populate the item list). Then I just want the selection of the item to pull the information to my form so they can update it and save the update(which I am pretty sure I can save the update as a php function but need to populate the item editable information in java script). I am really looking for help on how to setup the page with java script to make database queries and use the results to update parts of the page.In case you confused here is my flow:page loads

-User selects catagory query database for item list (on change event it think)
-User selects item.Item information is pulled and displayed from database(cost, serial number, quantity(another on change event)
-User is able to edit information and save updated results(run an update.php...)

Newline - Does Not Working After Retrieve A Record That Contains Square Symbol In The Database?

Dec 10, 2009

my javascript does not working after I retrieve a record that contains square symbol in the database. The square symbol should be a newline in a textarea. This is how the record "looks" in the table: [URL]

I am inserting the record using ASP and the value with square symbol is the value from a textarea with newline/enter. After that I retrieve the value using ASP and pass it to javascript and then the page is not working. If I retrieve other record which contain no square symbol then the script is working.

Use Ajax To Write To Database?

Oct 6, 2005

I know its primary function is to request information from the server, but can it also submit information? For example I have a page in which the user can drag and drop objects around (using DHTML) and I'd like to be able to dynamically store the coordinates of where they place the objects in the database without them having to click a "Save Changes" button ......

Ajax :: Call To Database Before Closing Row

May 17, 2009

I have a table with a list of games in rows. I want the user to be able to close/hide the game they don't want to play. At the moment I am using this;

Code:
<script language="JavaScript" type="text/JavaScript">
function removeR(r){
r.parentNode.removeChild(r);
}
</script>
<table>
<tr>
<td>Game 1</td>
<td><input name="button" type="button" onclick="removeR(this.parentNode.parentNode)" value="Close" /></td>
</tr>

<tr>
<td>Game 2</td>
<td><input name="button" type="button" onclick="removeR(this.parentNode.parentNode)" value="Close" /></td>
</tr>

<tr>
<td>Game 3</td>
<td><input name="button" type="button" onclick="removeR(this.parentNode.parentNode)" value="Close" /></td>
</tr>
</table>

This hides the games the user doesnt want to see on the page. But before the game is hidden I want to make an Ajax call to the database and add the user's preference into the table so next time the user comes to the page I can hide the game from the start. How can I do this?

Ajax :: Populating A Select Box From Database In IE

Feb 21, 2011

I am having an issue getting my select boxes working in IE. My current situation is that I have 2 select boxes, 1 for Styles and another for Substyles. Not all Styles have a Substyle, but each Style has a different Substyle, so when should happen is when you select a Style AJAX go and gets all of the matching Substyes for that Style.This actually works in Firefox, Google Chrome, Opera and so on, but does not work in IE.Just to clarify, all of my PHP is working 100% and as far as I am aware my HTML is also fine, I have done some checks with the JavaScript and im 80% sure that the problem lies on line 47.

Ajax :: Retrieve A Password Hint From Database

Nov 16, 2009

I have an ajax script that I would like to use to retrieve a password hint from a database.Both the ajax script and the php retrieval script are stored on the same domain (we'll call it domain1.com), but the ajax script runs on another domain (domain2.com).All the scripts are working fine, individually, but when I try to integrate them, I'm getting a ready state of 4, but an HTTP status of 0. I've traced the code flow and the retrieval script is being called by the ajax script OK and it's echoing all the right stuff, but it's just not getting back to calling ajax routine.

I've read that an ajax routine can only call a script that resides on the same domain that it runs on. Is this correct and, if so, does anyone know of a work around, because I really need to be able to store the ajax script on domain1 and run it on domain2?If not, then can anyone suggest why I'm getting an HTTP status of 0, when all the individual components are working fine?

Ajax - Handles Retrieving Data From A Database

Sep 2, 2009

Im having the weirdest problems with my ajax. Now first off i have horrible coding convention!! I have one Ajax.js file which handles all my ajax requests and one ajax.php file which handles retrieving data from a database. The problem I am having is when ever I call a certain method which contains a if statement and runs the respective ajax function, it sometimes evaluates the if statement wrong. The weirdest thing of all is when I use FireFox's firebug and step through the javascript code to see why its evaluating the if statement wrong, it evaluates it correctly.

So basically if I don't step through the javascript code it evaluates the if statement wrong which means one of my variables are not being set in time for it to be used in the if statement. BUT if i step through the code with firebug it evaluates the if statement correctly! Now I have tried this is all the browsers and sometimes it evaluates the if statement correctly and when i keep refreshing the page it will sometimes evaluate the if statement correctly! Now I know this makes no sense, but I'm just as confused! The only reason I can think why this is happening is that one of my variables are not being set in time for the if statement to use it!!

AJAX :: Auto Update Depending On Database Value?

May 13, 2010

I have a been developing an Online auction website using PHP and Mysql for the last few weeks. I have implemented everything including the 'bidding', 'buy it now' options of the auction etc.

I don't know much about AJAX to be honest, but I think it is the technology I need for this... My requirement is to devise a way of updating (in real-time) the current price of a particular auction product as more and more users bid on the item. Once a user bids on the item, the bid table of the database is updated with the highest bidders price. So once this value changes in the database, would it be possible to update the price on the webpage? Obviously, it is important for this update to be as accurate as possible to maintain the integrity of the auction.

SQL Syntax Error AFTER AJAX Updates Database

Apr 13, 2011

I want to have a textarea update a database column and then pull down the info from that column and display it, without refreshing. I'm using JQuery and AJAX and PHP and SQL to do this. So far I've been able to update the database row using my $.post() call. The strange thing is, my variables don't seem to be passing to the page - when I try to echo them or look at them they don't show up. Here is my simple index page and call (page names aren't indicative of what I'm trying to do, just placeholders):

<head>
<script src = "https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.js" type="text/javascript"></script>
<script type = "text/javascript">
$(document).ready(function() {
$("#updatefield").click(function(){
$.post(
'crud.php',
{
[Code]...

Ajax :: Query Database If Email Already Registered?

Nov 29, 2010

I'm making a little CMS, and I need to use AJAX to query the DB to see if an email is already registered. Here's my code so far:

The javascript:
Code:
<script>
function getEmail(){
var ajaxRequest;
try{
ajaxRequest = new XMLHttpRequest();
} .....

I'll test it by entering javascript:alert(getEmail()) in my browser, and it returns undefined. When I replace return 'valid/taken' to alert valid/taken, it will alert the values correctly, but for some reason it has to be entered twice (I have to hit enter twice in javascript:getEmail() for it to be correctly outputted). I'm relatively new to ajax and I think it might have something to do with the readyState not being correct.

Ajax :: Form Retrieves Results From A Mysql Database

This form retrieves results from a mysql database. It works fine but when I click submit it shows the result only for a second. When I hold down submit the result stays there. How do I get the result to stay on the screen after I hit submit? Even better how do I get it to spit out results without having to hit a submit button or press enter?

Ajax :: Check New Entries In Database And Send Response?

Apr 5, 2011

I have a simple AJAX chat room and it's taking too much local bandwidth when it downloads. What I want to do is call a page with AJAX that checks for new entries in the database and sends a response if there are new ones. But if there's nothing new it just doesn't respond. That way a user won't have to download a response with no new material. Is this okay to do? Am I correct in assuming this will have a positive affect on bandwidth?

AJAX: Populating Text Boxes With Values From Database?

Jun 18, 2006

I have a dropdown (picklist) on the page, and when the user selects one of the company names in the list the onChange event fires and kicks in some AJAX to get the company's details from the database. The details are just the various locations of each company.

The way I am doing it now I have a simple div on the page below the picklist and I am using PHP to draw out the entire HTML, including the values sought from the database, and then just using innerHTML on the div to dump the info in there.

So I have PHP which concats text like:

"<input type="text" name="city" value="$city">"
"<input type="text" name="state" value="$state">"

and then the JS innerHTML's it into the div.

But it strikes me this is not really an efficient way to do this. Should I just have the PHP form an XML doc and then use that to populate the form fields?

If so how do I use the DOM to create text fields on the page, and then populate them with the info returned from the DB?
