I'm trying to update a sql table from mi php Ajax web page, which stores dynamically a table into the page by table.appendChild(row) , so that the user can verify the information he is inserting before the actual database update.
How do I do this with ajax?
This jquery code pulls in an XML file, then passes the contents down to the nested POST call to add all of the records from the XML into a database table (which is handled by the saveSenatorRecord.asp file). This all works fine.. except that when the POST is called for "EACH" of the member nodes I expected the success: function to be called once after each of the records are added to the table. But what appears to be happening is that when function is called in the EACH property... it adds all of the records to the database table at one time, THEN it calls the success function once for each individual record.. but AFTER they have all been added.
View 1 Replies View RelatedWhat I'd like to do is have a dropdown box populated with data from a
database. Based on what you select from the drop down a table will be
generated (in this case a 3 column table) from another query to the
database. I will eventually want a way to select one of the rows from
the table, but for now I'd be happy with just generating the table.
I know it will have to deal with DHTML, dom documents, getElementID,
removeNode, recreating the node. What I am not sure about is how to
1) Dynamically create a table
2) Step 1 with data from a database (recordset)
Like I said, I'd also like to be able to select a row from the table.
I'd be happy with making the ros a radio group, though it would be
interesting to be able to select the row. I take it I'd use CSS to
highlight the row selected then.
I have a table in a database that gets populated by a client application. Whenever an entry is written to the table I want to fetch the data (which contains the longitude and latitude) and display a marker on Google Maps. I am using the Google Maps Javascript V3 API. Reading the tuples from the database is currently done through a PHP script. How can I update the map each time a tuple is written to the database?
View 1 Replies View RelatedI am working on a chat program. When a user logs in, a value in the database is set to 1 (online), and when he/she logs out it is set to 0 (offline). The problem is, when the user exits the browser, naturally the value is still set to 1.
I was wondering if it is possible using AJAX or otherwise to update the database on the event of browser close? I have tried onbodyunload in the body tags pointing to a file with a JavaScript function containing the PHP code (query to update the field) but cant get it to work.
we are developing an web application. In this user has an option to comment or mark a video. After user commented or marked it has to shown automatically on the page with out refreshing the page.

View 2 Replies View RelatedI 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.
I was wondering if someone could help me out with the following.I'm developing a webshop CMS in which you can create categories. By using jquery's ajax method I'm making a POST request to a PHP script which then handles all the data supplied to it. This works good and all except for the fact that after the query is being executed my HTML doesn't get updated, at least not as well as I want it to.I understand that the common way of working here is to update HTML in the success callback of the ajax method. But the thing is that every category is being displayed as a list item with an id attribute, this id corresponds to the id the category has in the database.If$.ajax tells me that everything went down smoothly and my query has been executed then there's still no way for me to know which id this new category has been given so that I can update the HTML accordingly.
What would be a "smart" way to tackle this? The first thing that comes to my mind is simply calling another script which figures out the last inserted id on the db but that would mean doing an ajax request in the callback of another ajax request? That doesn't sound right to me..
im trying to add a star rating system to a website. id like to do something elegant graphically instead of just using a drop down... the javascript framework im using is mootools and i found a great rating system here, but have no idea how to adjust it so that it updates the database with the new rating vote from the user and it calculates the new average rating.
the way i have the database set up for this is with the following fields: id (the rating's unique id) listingid (the listing that the rating corresponds to) userid (the user that entered the rating) rating (the rating itself)
i use php to communicate with a mysql database. the file im going to write will check to see if there is already a rating entered in from the logged in user. if there is, it will update it. if not, it will insert it, then it will calculate the average of all votes for that listing (rounded up) and return the new rating to the page and set the stars to reflect that rating... ive tweaked the code a bit to represent a 5 star system instead of a 10 star system and also so it can be used multiple times on a page.
heres what ive been playing with:

I have a problem, I am by no means new to PHP/Javascript but am finding an error that I cannot ridicule how to stop.Ok Ill try and explain it in simple terms:I have two divs, div1 and div2,In div1 there are links whitch are fetched from the databaseIn div2, content from links href ? in div1 is collected through AJAX.No I have a php preg_replace function that replaces it to look like <a href='#' onclick=\"showTopic(0,$char,'$1');\">$1</a> Now when you click this, it inserts into the "tpm" table in the database,(this table holds the links for div1) But it will not update the links unless i refresh the page? I would like to knoe how to update the links in div1 without refreshing, because refreshing = going back to the start of the code i am working on.
View 3 Replies View RelatedI am trying to create a web page in which the contents of one selection list
depends upon which element in another selection list is chosen, but where
the information to populate the first selection list comves from an SQL
database on the web server.
There are a couple of these situations in my application but, for example,
the first list might be a list of counties, and the second list a list of
states/provinces. Obviously the names of counties depend upon which
state/province is chosen, but there are too many possibilities to be able to
embed them within the web page itself. So when the user selects a
state/province I need to go to the server to ask for the list of counties.
I have seen a number of posts that sort of address this issue. For example
it is suggested to use <script src="a URL"/> to ask the server side code to
send up data of type "text/javascript". However the examples do not seem to
address how the server side code would know which state/province the user
had selected.
If there is a web site that addresses this sort of thing, I would appreciate
any pointers.

View 6 Replies View RelatedI'm trying to create a webpage where users can click on a dynamically generated set of questions:

and by clicking on a particular question, there will be an update for their particular listing of personal questions in a MySql database. I know how to create the database update part, but I think that I would need to javascript to:
1) tell my page that it's time to update (i.e. add a particular question as soon as they click it)
2) pass along the correct variable to the database update portion of the page.
Environment is PHP - MYSQL When the user changes the value of a select drop-down, I want to use Ajax and query one table of my database, retrieve three pieces of data, and place the data in three separate text fields in my form. Is there a simple tutorial out there that explains this?
I get the general concept of the separate php file for the query, but I'm pretty much lost.
I have a dynamic HTML table which gets populated by coldfusion and displayed in the page, I have a column called performace which holds numeric values. I need to select the top 3 best performace value in the column and then highlight the entire row in different colours (top 3 values for performance). Can any one help me in doing it?My server can run only Javascript and coldfusion, No Ajax/PHP.I need a complete set of code which such that I will add the script and it performs the calculating and highlighting part.

i am currently working on aptana studio nokia wrt plugin to develop a mobile widget where i need to retrieve data from database. i've created a java servlet in eclipse to connect and execute query to the ms sql server 2005 database. in aptana, i am using js file and html file, i'm able to connect to the servlet to retrieve and process the data (split the data) into an array and display the retrieved value (array) on screen. but now i need to put the retrieved value (array) into a drop down list for selection, how could i do that?
for the drop down list, i cannot define the list, it need to be able to read from the servlet as the database is updated, it need to reflect.
I'm working on a project which requires a small portion from a large table of information to be displayed on a webpage (sort of like a magnifying glass). The display will be a table of fixed size (m by n cells). Some of the cells will be merged. When the table updates, different sets of cells may be merged.
It needs to be coded in HTML5, which I assume includes the use of JavaScript and CSS (The specs of this is rather unclear at the moment, so I'm going to cover all bases).
Anyhow, looking through the HTML5 and JavaScript tutorials, I found two ways to solve this problem. One way would be to have a script to parse out the relevant information, and have it output into a table (dynamically generating the HTML required).
The second way would be to have the script draw the table on its own in a canvas.
User events (such as arrow keys on the keyboard) will change the position of the focus (move the magnifying glass in a cardinal direction).
I hit a small snag with the first solution - Is it possible to update the table on the page (including changing the structure of it) without having to refresh?
I've created some jQuery which remove many tr rows from my table and inserts new via AJAX. This indicate that the page is scrolling because first the table increase after elements is removed and afterwards it grows when the new content is inserted. Is there a way to let jQuery update this table without doing so? Eg. by first refreshing the DOM after I finish my manipulation. Here is a bit of my code:
$j(".bookingViewRow").each(function() {
$j(this).remove();
});
$j.get('cajax.php', {}, function(html) {
$j("#bookingView").append(html);
});
I have a table with rows and in each row there is a cell which shows the status of the row item.<a href="#" id="<?php id ?>" class="status_button">Online</a>When I click the link in a row the next code is activated (found it somewhere on the net).
$(".status_button").click(function() {
var id = $(this).attr("id");
var dataString = 'id='+ id ;

I have been trying to figure out how to go about making a table of comments auto-refresh when someone inserts from a comment form without refreshing the whole page.I've tried looking into AJAX for this, but everything I have looked at, in terms of tutorials, just flies right over my head, and I can't really make much sense of it.

I would like to be able to generate a table from which I can easily edit the contents of a mySQL database (similar to phpMyAdmin.) In that table I would like to have a button that will open a pop-up, allowing me to edit - and maintain formatting such as apostrophes and line breaks - a long description field. That popup will then populate a hidden input field on its parent with the modified description.
I've got the pop-up opening and its fields are populated using php's GET function (see line 11). The special characters, particularly carriage returns, are messing me up; I can remove them using php's str_replace, but I want to retain them for formatting.
