Ajax :: Php Pull Unique Url From Database To Match Data On Screen
Jun 9, 2010
we have product pages; example page: [URL]
there is a selection of menus on the screen that you can change select different options to show you a price.
issue is as follows; i want to be able to create url's for every product in the database for google adword purposes; for example if they click on the google ad they come direct to the page/selection from the table/drop downs that is what they want. currently we have got as far as creating the below link;
[URL]
this link will take you to the product, but the drop downs from the menus haven't changed, just the price and the quantity.
i need to know of a way of selecting from the database and it be able to change the drop downs from a specific url.
our problem is we need to populate a select option in order of the one we send.
I'm trying to pull data from multiple database tables and output them into a table which I've done fine, but I'm having trouble trying to filter the rows by specific values like colour and size selected from select boxes without reloading the page.
After more than a day of looking though I have made no progress, If this was to be done with just PHP and MySQL reloading the page I'd have no problem but having problems with the AJAX side.
I'm very new to jQuery, only picked it up yesterday, so there is very little I understand at the moment. I have a website on which I would like to display a real time, time-series chart displaying results from a database that is constantly updated. how to pull live data from my database and display it in an alert box on my sight. One of the replies said I should use jquery to achieve this.
i am trying to build my form to submit without reloading the screen. I am using jquery and it inserts the data but it also reloads the screen and two database records get inserted. It appears that one is being inserted by jquery and the other is being inserted by the normal form submission. How do I remove/override the normal form submission? My html code is as follows:
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!!
I want to build-up ajax based friends system. though i no nothing about ajax (would like to learn but) actually i have form where user can add his friend. on very next page of this page he/she can see what he/she is entered and where
they should probably see the add and remove button(which i want to build up using ajax)
how to start for this? till now i have code where user can write his friend name and to the next page he/she can see the value he has written. on submit button it all goes in to database. means i have devloped php form for this.
I have got some code working below which creates a nice effect when shopping on a website. Basically i have a large image, and 4 thumbnails below, when i hover over the thumbnails the main image changes to match etc..Now i would expect this to work, but i dont know how to change the JS at the top of the page to match my requirements? The JS at the top is also selecting images 2,12,11 and 13, but again i want this to be linking to my table from database..
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...)
could someone please point me in the right direction for creating an AJAX page that displays "live" data from a mysql database? I need the page to update its self every time data changes in a mysql table.
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.
I am following the following example to create predictive text pull out of the database.[URL]... Seemed quite easy but it seems like it's not working for me, maybe because i'm doing something wrong?
This is the page:[URL]... If you start typing in the big search box the suggestions box appears in the wrong place, and it should be returning some results but it's not.
I have an ajax function which passes form field values to a PHP script which in turn saves the data to my database. all works great.
I now need to add a file input to my form and pass the file upload ot the same PHP script.
I have read an article [url] which explains how to do this but this would suggest it is a completely separate function.
My question is, is there anyway I can expand my existing function (below) to inlude the file upload process to save having 2 functions doing the same process?
there's a line in my Javascript program that makes a change in the appearance of an area of the screen. it is a game program, so there are a cascade of changes after the user makes a move. these are carefully sequenced and timed in a loop which contains the "action" statement
document.images[k].src = offGIF[currNode];
unfortunately, the *actual* screen updating appears to be 1) asynchronous and 2) faulty!
_asynchronou_s in that things change in the wrong order, as if each has its own thread and they run at random.
_faulty_ in that occasionally an area that would change from, say, picture1.gif to picture2.gif and back again (according to game logic) lands up showing picture2.gif. even though the internal game logic has it recorded (and i assume document.images[k].src would be correct, even though the screen is not) as picture1. so.
is there a way to wait or surrender control to the system until the program statement's intent has actually been rendered to the screen? something i can test to see if the unerlying system mechanism has caught up with all changes to document.images?
I'm having some issues with my code. I'm trying to pull data from one array and use it to populate a new array. With my initial array I can get the results of certain properties using 'servos[i].application'. Any servos that share their value with that of my filter box should be put into a new array called matches and allow me to referance them in a similar way 'matches[i].application'. At the minute I've got my code to populate the new matches array, i'm pretty sure, but when I try to get data out of the second array using the 'matches[i].application' style of query it says its undefined. I already have an array called servos which is full of 49 different servo objects. I've added the function containing this code and commented it too.
PHP Code: function dataPull(){ //create servoStore to build page for display //var servoStore=""; // search and get servos meeting application filter settings // create new array called matches with set properties var matches = new Array("application", "sclass", "type", "motor", "bearings", "gears", "modelno", "name", "speed", "v3_3", "v4_8", "v6_0", "v7_2", "weight", "dimensions", "opvoltage", "image", "description"); .....
I am writing a small data entry screen that will post the form data to a page and return a message. But i cannot get the Success or Error functions working properly.
Here's the code where strData is the posted querystring of:
I'm not sure whether it should be in a form and using the onsubmit or click of a button.
I would like to use jQuery to prepopulate a form - ie make a call to a php program to get data from a database and pre-populatea form with appropriate data for the user. Can anyone point me in the right direction for some examples on the simplest way to do this?
For the first time in a long time, I've encountered a project with a single image that has many regions.Each region is a polygon, and will bind to a unique rollover event. That rollover event will pull back data for each region.I've thought of using a hidden image in a canvas with a black background, and a different color foreground for each region. Then, mapping the color the proper region data on the backend.I've thought of passing a huge Javascript object with keys that relate to a position in the image, and values that define the region data.Initially, I dismissed the idea of a good, old-fashioned image map, in an attempt to find something sleeker and sexier. But perhaps this is the best solution?
I know it's messy and all to send data this way, but it's what was decided on, so here's what I need to do with it. I want to take all the info from the query string and post it into the corresponding form fields in the document. So I need to somehow isolate the query string (maybe a global JS variable? maybe another method?) and then I was thinking it would work to somehow pull each piece of information delimited with &= and put them into a simple array (split() method?). Once I have the info pulled from the URL into an array, I thought I could simply update the field's value attribute with basic javascript like this:
form1.SubscriberID.value=1523;
Then, all the values would be automatically loaded into the correct form fields. But, since I'm a js newbie, I really dont know how to go about this. Ideas? Examples? Remember I'm new, so explaining every process might be in order.
what i want to do is have a selection from 'tst' trigger an input into 'choose' from the data inputted into the 'fname' and 'lname' fields.
for example, i want option '1', when selected to draw the input from 'fname' and place it into 'choose'
or i might want to select the data in 'lname' instead, so i will tie option 2 to it, so when the user selects option 2 the contents of 'lname' go into 'choose' instead.
I have a bunch of dynamically created divs which I need to loop through and then display text inside which is obtained via AJAX.
<div class="appStatus" id="appStat_1>TEXT FROM PHP PAGE</div> <div class="appStatus" id="appStat_2>TEXT FROM PHP PAGE</div> <div class="appStatus" id="appStat_3>TEXT FROM PHP PAGE</div>
Basically, I want to loop through all divs where class = appStatus and on each iteration pull data from a PHP page (via AJAX) to display in the DIV. I need to send the value after the _ of the id (which I can obtain using substring) with the AJAX request in order to return the correct text.For some reason.I know that I need to do something with
I have some form fields that the user can either type in or he can check a checkbox so that MySQL data for an option selected from a dynamically generated (PHP/MySQL) select menu is filled in. How can this be implemented? I have the code for the select menu.
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.
