JQuery :: Send Variable Using Ajax To A Php File And Insert It To Database?
Dec 24, 2011
i am trying to create a form that where the page will not refresh if the form is submitted specially if the user inputs any errors in the form my problem is i do not know how to send multiple variables using jquery to a php file i saw somewhere that in order to do this you need to concatenate the variables you will be sending this is the code i am using
<html>
<head>
<style type="text/css">
#add(display: none;}
[code]....
the jquery successfully sends the variable to the php file the problem is once i insert it into a database all the variables i sent are concatenated for example in the column stud_no once you send the form this is what will be inserted "123123name=asdasd"

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:

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....

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?

I too have a problem with Ajax POST method and Send. I have set up a Site Search using the Google Ajax Search API, and it works fine. The search term is stored in the variable (?) query. Just to make sure, I have set up a new variable (searchTerm) to read the value of query, and a temporary Alert box shows that this variable does indeed contain the search term.
I want to store the search terms in a database so I can see what people are searching for. So I set up a POST method to send the searchTerm to a php file, which uses if (isset($_POST['searchTerm'])) to obtain the searchTerm and then insert it into a MYSQL database. But it doesn't work.
When I couldn't insert into the database, I added a second (temporary) insert using a dummy value as the else part of the above if statement, to test (1) if the Ajax file was actually setting the php file going, and (2) to check my Insert code was working. Both work.
So the problem is clearly that either the Ajax code doesn't Send correctly, or the php isn't receiving it. I am stumped to find what is wrong. Here are the two relevant sections of code:

To repeat, the php is running and always loads the dummy variable from the else section, indicating that isset($_POST['searchTerm']) is null.

I've used a few jquery things before, but I haven't a clue when it comes to javascript, so I've mainly just modified variables here and there. This is my first attempt at actually writing something, and well.....its not working
Im trying to send an ajax post to an external file, which simply returns 'Complete' after updating the db. My html gives me an ul, with li elemnts, representing names of comics.
Anyway heres my code:

Ok, so I've built a member search using ajax to change the results each time a filter is changed. It works great, except one minor issue that I'm struggling with...I just can't specify dynamically in the parent file that linkclass$id opens linkclasscontent$id as I don't know of any way to pass that $id variable back over to the parent.

I've the following AJAX code:
[Code]...
This code works to insert a MySQL record to a Database using AJAX. It works fine on IE, but it's not working on FF or Chrome. When I test it on FF/Chrome, i just get the text "Just a second..." and it doesn't advance from there.

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.

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?

I wanna send a file thru the JQuery.load, I want it to work exactly like the regular post without the JQuery. So I can check the $_FILES['file']['error'] in PHP and all its features like I do without using JQuery.
$("#load").load('gerenciar_itens.php',{/* This is where I wanna pass the file. */}, function(data){
alert(data);
});

I have a function which has two URLs that need to be posted via php onto a database. I had them as individual functions and they work fine but ideally I would like them to be done in the same function. For example, like the following...
if (request !== null){
request.onreadystatechange = loginsuccess; //function to check RS=4 & Status = 200.
request.open("GET", urllogonsubmit, urlrecieveemail,true);
request.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
request.send(null);
}

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 have this table:CREATE TABLE IF NOT EXISTS Assignments (uid TEXT PRIMARY KEY ON CONFLICT REPLACE, instruction TEXT, start TEXT, stop TEXT, createdTimestamp TEXT, theTimestamp TEXT, taskID TEXT, resID TEXT, flowID TEXT, flowDefID TEXT, currentState TEXT, iconRef TEXT, colorRef TEXT, dispatched BOOLEAN, inStartState INTEGER, inStopState INTEGER, writeLock INTEGER, workItemID TEXT, companyID TEXT, metadata INTEGER)
The thing is that when making a insert and then going to the development toolbar in chrome and look at the storage tab and look at my table. Depending on what is in the table chrome crashes.I drop the table between the executions.The difference here is that "theTimestamp" is something rather then empty. If I set theTimestamp to '10/15/10 3:07 P' it works. But just adding that last M or any other letter will make chrome crash when you try to look at the table. Whether it is by navigating to the table with mouse clicks or writing a select * from Assignments statement.
