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 :: Display Mysql Php Result?

Nov 20, 2011

I am not a javascript programmer, however are checking as I would like to investigate if I can do following:

I have a calculator that check the price for the properties for a choosen date, I use php and mysql to get the result and the result are displayed on the same page refreshing the page using this in the form: action="<?=$_SERVER['SCRIPT_NAME']?>#formdestination">

I know you can print the result using ajax or other javascripts to do this without having to refresh the page and jump to the result.

Was doing a research and I quckly found this link:[URL]..It does not look so complicated, however as I can see the form is done in javascript so I suppose if you have javascript disabled you cant use the calculator.

I would like to have a non javascript solution with the way I am doing it to work if javascript is disabled. An exampel of the calculator can be viewed on this link for exampel:[URL]..

AJAX :: Pull Back MYSQL Table

Aug 4, 2010

I am trying to use AJAX to pull back mysql table information. I tried to alter an example I found (w3 schools) where they showed how use a selection table to pull a specific line out of a mysql table, using the "q" (not really sure if the "q" character is important or not). xmlhttp.open("GET","xxxxxxx.php?q="+str,true) I follow what they were doing there, but I want to pull the entire table back not just specific lines. (So I got rid of the Q)

Here is a snipit of HTML. The showdata function is part of the testpull.js code. You click the button and it should run the javascript to pull back the entire table and place it in the "placedata" div section.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html lang="en" xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">

Ajax :: Form Field Validation Using PHP, And MySQL?

Nov 25, 2011

Ajax and jQuery is something I'm new to, but PHP, Javascript, and MySQL I'm pretty well seasoned with.For starters, I want to create a simple form where there are these fields:Name (text field)E-mail (text feld)Zip Code (text field)Cell Phone Number (text field)Phone Carrier (dropdown menu)Thing is, I want to check the database to see if an e-mail address has already been entered. I'd like for that to happen after they enter the email address and tab or click out of the e-mail text field. For instance, after they enter an e-mail address and tab to the Zip Code field, the script queries the database to see if that e-mail exists already. If it does, it notifies the user and greys out the submit button. If not, they're allowed to finish filling the form out and submit. It'll be a huge time saver if this Ajax script is in place.

AJAX :: Auto Refresh Data From MySQL

Dec 13, 2011

I am attempting to create a profile page with PHP utilizing AJAX technologies as well. I need profile data to auto-refresh on the page when a change is made in the database but every 15-30 seconds intervals are fine too. I would really like to use AJAX/PHP for this because I think it will be good for me to know and learn.

I have checked the internet for this and all of the examples show a form select/combobox where you select a "User" and then it populates the information automatically in a div below.

But... I need AJAX or PHP to READ THE VARIABLE FROM THE URL instead of a form(Combobox) and ultimately refresh the data on the page with the results from the DB query in the php file.

Ajax :: Form Retrieves Results From A Mysql Database

Jun 22, 2011

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 :: Synchronize A File Upload With An Insert In MySQL Through PHP?

Sep 17, 2009

I'm using AJAX for all the updates to the web site I'm building and it works very well. But now I face the need to:

1) Upload a file (an image or video) to a folder in the server.

2) Insert a row in MySQL with the name of the file plus some other information (year and a comment).

The user would upload the file and fill in the information in the same window, and should have a single message (if possible) saying that the file was added or not (meaning both the upload and the insert).I have been doing some googling and found information as how to simulate and AJAX upload, since it seems AJAX does not support file uploads (hope I'm wrong). This is what I found: [URL]

So following that example I could upload the file, and I'd have all the information from the form, in the PHP, and I could synchronize the upload and the insert, but then I can't figure out how to send the OK from the PHP to a Javascript (i guess) to update the html and display the message in the web site.

Ajax :: Dropdown Menu Pulling Info From MYSQL Database?

Jun 20, 2009

I need to create three dropdown boxes (box 1:colour, box 2: price, box 3:brand) and when the user presses "GO" they are returned with the correct information, pulled from corresponding fields in my MYSQL database.

For example, colour: silver, price 100-200, brand:samsung...should return 5 items on the page. I do not need the dropdown boxes to populate depending on ther previous selection - they are static, so to speak. If possible, I would like the information to be retuned to my page without the URL changing, which leads me to think I will need to be ausing ajax....?

Ajax :: Combobox Autocomplete - When The Client Types On The Drop Down, The Records Appear From MySQL Database?

Apr 14, 2010

I am looking for an Ajax combobox (drop down, not a text box) auto complete script. I searched for it on Google and only result which seems similar to what I am looking for, is dhtmlxCombo. And that one is too complicated for me. What I basicly need is:

When the client types on the drop down, the records appear from MySQL database and when the client chooses one and submits the form, I want the ID (not the text written) to be posted.

AJAX :: User To Be Able To Edit The Data Set And Have Those Changes Written Directly Back To The MySQL Database?

Jul 11, 2010

I have a form.On the form I have a drop down box that allows the user to select a data set to work with (A or B). The table loads just fine and all is right with the world. No problems there.What I need is for the user to be able to edit the data set and have those changes written directly back to the mySQL database. They also need the option of deleting a record entirely.I know how to do all the database queries, updates, etc. I just don't know how to write the ajax forms to accomplish this.

Ajax :: JQuery Return Value Always Has A Zero (0)

May 21, 2010

I have researched this error/bug/mistake thoroughly with no success. I must be the only one experiencing it. Also, this takes place on every site I develop with jQuery ajax. It happens regardless of whether I use .get, .post, .ajax etc. Problem: The result returned to my ajax function always has a zero (0) appended to it.

Ajax.Request Return Value

Sep 12, 2006

Anyone know how to return true or false to an event handler based upon the results that come back from a Prototype Ajax.Request call?

I have a link with an onclick handler that calls a function getLoggedIn(), which looks like the following:

function getLoggedIn(type) {
ajax = new Ajax.Request(
'includes/checkloggedin.php',
{
method: 'get',
parameters:'&type='+type,
onComplete: checkLoginResult
});
}

As any analysis of request.responseText occurs in checkLoginResult(), not getLoggedIn(), how can I pass an Ajax-response-determined return value back to the event handler?

Return Html In Ajax

Nov 27, 2006

I'm new to ajax and coded a script that returns the result of a php file. It is fine if it is just text, but if it has html included it prints out the tags instead of treating it like html. How do you treat it as html? I've heard of innerHTML but was told it isn't viewed as standard compliant and some browsers don't even support it.

JQuery :: Getting A Return From .ajax Function?

Nov 14, 2011

I'm trying to make a call to .ajax and as a result set a value in a hash (for another call to jquery-ui)

I get the data coming back fine, could put in in a text field in html but not the hash where I want it.

Here below are the parts of my code that I'm using

//setting up datepicker
$(courseStartDateHtmlId).datepicker({
.....
defaultDate : ($(courseStartDateHtmlId).val() != "") ?

[Code].....

I thought that the value of startDate would end up as the defaultDate param for datepicker. No luck. Only an obscure little message in firebug console: "missing: before statement"
