View 24 Repliesi'm having the user input their state (from a drop down list) and type in a zipcode (there are 1,143 zip codes in the database to match to)..
what i want to happen is once the user selects the state they live in, and type in a zip code, i need the page to query the database if the user selected Ohio, and match the counties in the database with the zip code they entered, and then create a drop down list of the counties for them to select the one they live in Code:
If I want to show the result of a database query, every second or so, is the best method using javascript/ajax with a set interval of a second to call a PHP script and update the DOM, or is there some other method better suited to this that would not have the cpu overhead if there were many users on the site.

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.
I am making a webpage that can query a database table of employees
and return them in a html table. Currently I have submit buttons beside
each employee to open the page to edit their details. I have been using
php/HTML to do this, but wondered if it is safe to use javascript to
just click on the name of the employee to jump to the edit page. I've
been looking on the web for sometime about how to do this without any
luck. Any thoughts?
I am starting to find more web pages that are using a query parameters
after the JavaScript file.
Example can be found at www.opensourcefood.com. Within the source
you'll see: <script src="/shared/scripts/common.js?revision=1.6"
type="text/javascript">.
I am trying to see if there is any big deal to this or a best practice
that is starting to creep up in the JavaScript community. If this is
used only as a way to distinguish what file of JavaScript being used
why not append something inside the file? Has anyone else seen this
or know of more reasons to do this?

View 4 Replies View RelatedI have a website that uses javascript to communicate with the database for the CMS system.
I had a programmer develop a website who refuses to add a logical function to which I am going to have to do myself now.
When you delete an image or file on a page of a website, it does not delete it from the server. It just deletes it from the website and database only and I can see how this will eventually cause problems when files accumilate in the server.
Can someone give me some samples, direction or instructions how I would implement a function so that when the admin deletes the image on a website, it also deletes it from the server itself.
I'm in the process of building a web application designed that allows users to embed it into their site using XSS (like adsense, Digg, Reddit, etc). Since XSS requires a Javascript file, I'm having difficulty figuring out how to implement information from a database. In a nutshell, what I'd like to be able to do is allow for accepted users to run my application on their webpage. Which means I will need to pull a client ID from a database, and only allow the user to run the file if their client ID is valid.
However, I haven't the slightest clue how I can perform this since there doesn't seem to be any means of running PHP inside my JS file and have that transfer over to the other user's site. I'd also like to avoid having every single valid ID directly listed in the JS file if possible for the sake of security and avoiding massive clutter and file size. Does anyone know a good way to achieve this, or an alternative way to achieve essentially the same result?
i'm busy making a site for a audiovisual company and i'm stuck at the CMS system by adding pictures to a project page. Adding one single photo isn't the problem but I want a button to add a new file input field and insert that second (or thirth, fourth etc etc) into a new row in the database.... The script that i'm using right now, clones the input field but doesn't "activates" it.... You can't select a file....

View 6 Replies View RelatedI 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?
