Load JSON Data With PHP And MySQL?
Jan 25, 2011
{URL]
and I changed it round slightly, I would like the first select box to be Search by either Town or County - Having links would easier?! [URL]
So, when a user selects Town, the PHP selects the Towns or if the user selects County, then show the Counties list
I am currently getting the following error: $ is not defined [Break On This Error] $(document).ready(function() {
here is my HTML
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

I have a html file that I want to load, loop through the json data and for each json entry I want to add a new block of the html and insert the json data into the matching div/class of the html. json looks like this:
{"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
html looks like this:
<div class="Name"></div><div class="Age"></div>
So for each json entry of name/age, I want to insert that into the html, and then add another row, until all json data has been fetched. After this I want to insert all of this into #box, which is just a divthat should contain that html. Looping like this obviously does not work, since I just keep replacing the same html through the loop.
var jsonData = {"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
$.each(json.Super, function() {
$('#box .Name').html(this.Name);
$('#box .Age).html(this.Age);
});

I am doing some development using jQuery $.getJson lately and found the following weird scenario.
1. open google chrome without any argument then load a local html file.
2. the local html file will need to have $.getJson[url] .... bla bla bla and jQuery.support.cors = true.
3. data will get loaded
But if you try to load the exact same json data from other domain or localhost, it wouldn't works.

I have a JSON structure in API.When I call the API in my code it returns as the same JSON .I have to print this JSON result as table with pagination in Javascript. The table should be dynamic with previous and next buttons and the table should populate the results according to the JSON and each page should have 20 entries and then the remaining entries should go on the next page and I should be able to go back and forth in the table using previous and next respectively.tell me the exact code of how to start with getting JSON from the API and then write the JSON data in the form of dynamic table with pagination.

Your table-driven application has a MySQL table on the server side and you want a Javascript associative array on the client side to do rapid look-ups.For example: My application uses the value selected from the form’s drop-down menu to choose which other form fields to hide or show. This choice of a 'Long Form' is table-driven from product data in a MySQL table.
Convert the MySQL table to an associative array in JavaScript.I am using the jQuery library to manage the presentation and form validation on the client side and PHP and MySQL on the server side.Since a JavaScript Object is an associative array and the MySQL table is being used as a look-up table (associative array) I use the PHP function json_encode to create a JSON string - JSON is JavaScript Object Notation - on the server which is then evaluated as a JavaScript Object on the client. The two parts (server and client) of the code are listed below.All very straightforward then. So why the blog?This is what I do (here's the PHP code):
do { $key = $row['ProductKind'];
$value = ($row['LongForm'] ? True : False);
$arr[$key] = $value;
[code]...
As a newcomer to jQuery this is a good opportunity to show my appreciation to John Resig and the people that have contributed to the jQuery library ... not forgetting those who have integrated all the MySQL and JSON stuff into PHP. It's all very neat ... when you get to understand it!You could just eval(data) to turn the JSON string into a JavaScript Object (a.k.a. associative array), but JSON.parse protects your code against evaluating malicious scripts that could be embedded in the JSON string. This function is found in the json2.js downloadable until included in native browser JavaScript engines.The PHP Booleans translate automatically into JavaScript Boolean types.
[Skip this: My application has a MySQL table of product categories that tell me whether I need to present the administrator with a long form or a short form in the HTML. So, as products are added over time, I want to the administrator to choose whether a new product category can take the short form plus some default values or will require the explicit input of all product values in the long form. As the administrator assigns a category to a new product - and changes his mind half a dozen times - I don’t want to keep on going to the server to do the look-up but want to have the table in Javascript to keep the form presentation responsive. Also, the MySQL tables are on a third party’s server remote from the web server.]

I have just started to learn about JQuery and wanted to learn how to retrieve data from an API.
I used the Flickr example provided here [url] and just changed the relevant code to point to the 500px api.
<body>
If I launch the following URL I do get the results properly [url]
Here's a sample of what the result looks like:-
I don't get any results when I run my code page. What am I doing wrong?

I'm trying to compare incoming JSON data to the existing data to see if there are any changes, but for giant objects like:
Code:
[{"date":"2011-09-03 23:06:03","notifier_id":"1","type":"1","unread":"0"},{"date":"2011-09-05 00:37:46"}]
if (JSON.stringify(oldData) == JSON.stringify(newData))
This doesn't seem to work. I've tried using:
Code:
escape("'" + JSON.stringify(W.notification.list + "'"))
but that ignores the objects properties and returns something like 22%5Bobject%20Object%5D%2C%5Bobject

I have a database holding roughly 20 fields of data per entry. I want to make only one request to the database, store this information in some manner on my client, and then use javascript to deliver this information to the user. Initially the user will be presented with just a list describing each entry, when clicked upon, all corresponding fields will populate. I know how to do this with javascript fairly easily, but I'm not confident in my methods for getting that data from my database ala php to javascript.
The first thing that comes to mind is to write some PHP code to pull from my DB and then echo out a two dimensional javascript array. I have seen posted elsewhere that this method is not ideal... And I can see why as I always run into issues with attempting this... plus it is ugly as all hell. What is clean way to get all this information onto my client so no subsequent server requests must be made?

i have a script which i found on the internet. i modify that script according to my needs. what is in that script is there are three form fields with two buttons. one button is "Give me more fields" clicking on this button will give you more fields. and second button is submit so the data goes to server side and will be added to db. the problem is when i click give me more fields it gives me three more fields which is right but when i fill all these fields and click submit button it adds to the db but the data in the first three fields adds in the one row and the other three fields data adds in separate row which is not fine for me. so how can i do this so all the data will be added to only one row.
here is js code
Code:
var counter = 0;
//Start a counter. Yes, at 0
function add_phone() {
counter++;
[Code]....

I am trying to set up a web based tool for my wife and I to use to balance our checkbook together. I am using HTML, Javascript (Ajax), PHP and MYSQL. I have read beginner books on all of these subjects, I can get data out of MYSQL, BUT can't do it the way I want to do it. If someone could point me to a book, or even the name of what I need to study it would be very helpful. The top line will always be input. But as you submit the top line it refreshes the "growing list" beneath it. (kind of like on-line banking, where you can look at 50 or so lines and then go back further if necessary) The catch is within the "growing list" I want to show Bank and book balance running totals and have three buttons next to each transaction ... EDIT DELETE SUBMIT. If edit is clicked, I want to be able to change that line and then resubmit it to MYSQL.
[Code]...
This way we can both input our transactions as we spend money and know at all times how much money is in the account. What do I need to study to be able to program this?

I have a database listing of properties down the page. Each property row has a date selector and a time selector. I need to somehow validate that if one of the dates is selected the time must be selected per property record before the bulk save can happen (or visa versa), if neither are selected it cane be left blank and addressed later. How I can go about validating this using jquery?
The field names are as follows:
DATE - data[Property][777][entry_date]
TIME - data[Property][777][entry_time]
NOTE: 777 is the property ID and changes per record down the screen.
I basically need something such as within a function to run dynamically:
if(data[Property][$id][entry_date] <> NULL) {
data[Property][$id][entry_time] is required
} else if (data[Property][$id][entry_time ] <> NULL) {
data[Property][$id][entry_date ] is required
}

I want to query a MySQL table when a php webpage initially loads and display the data. Is there a way of executing a php script using the onload() function directly other than using Ajax?

I am having a problem sending my form to MySQL on my application page (when you click GameTime! it should send the data to a MySQL table.)-[URL]
It sends the form data here: [URL] however, it just won't seem to work in facebook. Obviously there is something wrong with my FBML/FBJS.
This is the JS I use to do this:
function getPicks(){
var j;
for(j=0; j<5; j++){
var div=document.getElementById("li"+j);

I have a .load that executes a php mysql query from another page. This query displays all the data of the database. Each result is wrapped around a div.
<div id ="post<? echo $row['post_id']; ?>">
the id of the div depends on the post id of the result. How do I put the data of $row['post_id'] in my javascript?

I'm trying to dynamically retrieve data from database and stuff all these data into an empty select list thru javascript. But I can't get it to work
PHP Code:
while( $row = mysql_fetch_array( $sql ) )
{
$getChildren .= 'var newCElem = document.createElement("OPTION");'
$getChildren .= 'newCElem.value = "' . $row['id'] . '";'
$getChildren .= 'newCElem.text = "' . $row['label'] . '";'
$getChildren .= 'allPaths.add(newCElem);'
}
$getChildren will be spit out to my javascript code part where I've place <%getChildren%>. When I try to manually type in the output into the javascript code, it works but not when dynamically.

Not sure if this is the correct forum as it covers data retrieved from mysql in a .js file...
I need to grab the last 5 rows from my database (2 fields per row) and list all 5 in a table but from within a .js file that I can externally link to.
I can manage the php / mysql and the output to a .php page but how can this be contained within a .js file?
I believe it is possible but after 2 days of searching on google I'm appealing for assistance.
I realise this could be done with a php include or iframe but that isn't an option and the only way available to import this data is via an external javascript script.

I have my doubts if this question belongs to the javascript side since it's all good until the data from MySQL comes in, but since the javascript is the one breaking I'll take my chances.
The external js (portada.js)
Code:
$(document).ready(function(){
var currentPosition = 0;
var currentPosition2 = 0;
var currentPosition3 = 0;
[Code]....
As you can see I have three divs with different slideshows (slideshow, slideshow2 and slideshow3), they have products that slide to the left. When I was testing to make sure it all looks good the sliding feature was working fine, but I lost this feature when the data was being retrieved from MySQL (at the moment on <div class="slide">).
