update sql record using javascript - php

Question

I have a simple form before:
<form method="post" action="firstbillsubmitbal.php?id=#COL1#">
<input name="currentbal" type="text" id="currentbal" class="input-mini" />
<input type="submit" id="submit" value="Save" class="btn btn-success" />
</form>
Which calls this page for processing firstbillsubmitbal.php
$dealID = $_GET["id"];
$currentbal = mysql_real_escape_string(stripslashes($_POST['currentbal']));
$sql = mysql_query("UPDATE deals SET
currentbal = '$currentbal',
currentbalDone = 'Yes'
WHERE deals.dealID = '$dealID'") or die (mysql_error());
It was working fine for single transactions. But I need to edit it a bit since I am displaying my data in a table now. I now have this js code when I click on a btn on my table per row, passes my row_id and currentbal calue, I got it working but I would like to know from this js code how do I process my form?
function funcEdit(row_id){
var currentbal = document.getElementById('currentbal' + row_id).value;
var r=confirm("Are You Sure You Want To Proceed?");
if(r==true) {
alert("Record is saved");
} else {
alert("Cancelling Transaction");
}
}
The js code has two variables only at the moment which is
row_id = this is basically the ID of the db row and
currentbal = which is the value I want to upload to my db
My question basically is how do I call my firstbillsubmitbal.php file and what/how do I edit on my php file so that my row_id and currentbal are uploaded on my db since I am no long using POST.
Thank you for the replies. So I went thru some SO answers and some tutorials I found on google and this is what happened to my js code.
function funcEdit(row_id){
var currentbal = document.getElementById('currentbal' + row_id).value;
var dealID = row_id;
//organize the data properly
var data = 'currentbal=' + currentbal.val() + '&dealID=' + dealID.val();
//start the ajax
$.ajax({
url: "firstbillsubmitbal.php",
type: "GET",
data: data,
cache: false,
success: function() {
$('#message').html("<h2>Current balance has been updated!</h2>")
}
});
}
And this is what happened to my firstbillsubmitbal.php page
$dealID = $_GET['dealID']
$currentbal = $_GET['currentbal']
$sql = mysql_query("UPDATE deals SET
currentbal = '$currentbal',
currentbalDone = 'Yes'
WHERE deals.dealID = '$dealID' LIMIT 1") or die (mysql_error());
But nothing happens when I click on the button to call my function. What am I missing?
Also, here is how I call my function. #COL1# is my row ID value.

Answer 1

Are your function getting called correctly with row_id data ?
if so then might be this will give you a trick,
function funcEdit(row_id){
var currentbal = document.getElementById('currentbal' + row_id).value;
var dealID = row_id;
//start the ajax
$.ajax({
url: "firstbillsubmitbal.php",
type: "GET",
//pass data like this
data: {currentbal:currentbal.val(),dealID: dealID.val()},
cache: false,
success: function(data) {
if (data=="1")
$('#message').html("<h2>Current balance has been updated!</h2>")
}
});
}
and in php file
$dealID = $_GET['dealID']
$currentbal = $_GET['currentbal']
$sql = mysql_query("UPDATE deals SET
currentbal = '$currentbal',
currentbalDone = 'Yes'
WHERE deals.dealID = '$dealID' LIMIT 1") or die (mysql_error());
echo "1" ; // if update successful
else echo "0" // if update unsuccessful

HTML :
<form method="post" action="firstbillsubmitbal.php">
<input name="currentbal" type="text" id="currentbal" class="input-mini" />
Update
</form>
JS :
function funcEdit(row_id){
var currentbal = $("#currentbal").val();
//organize the data properly
var data = 'currentbal=' + currentbal + '&dealID=' + row_id;
//start the ajax
$.ajax({
url: "firstbillsubmitbal.php",
type: "GET",
data: data,
cache: false,
success: function() {
$('#message').html("<h2>Current balance has been updated!</h2>")
}
});
}
Hope it works for you!
