PHP - Need Some Help With Json /jquery
Hi, I am working on a project to help me learn more about JSON and JQuery and how they interact. I am able to pull in my JSON data fine and it displays in an HTML table. What isn't working is I want the tables rows to be striped, and normally this works, but I didn't know if it isn't working b/c it is AJAX or if I have something wrong with my JQuery. Also, I was hoping to add a reference to an image path in the JSON file as well, but wasn't sure how that is done or if it could be done at the JSON level.
Here is my code that I am working on:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>JSON Presidents</title>

padding:10px;
margin:0 5px 0 5px;

})(jQuery);
</script>
<script>
$.getJSON('data.json', function(data) {
var output="<table id='data'><tr><th>First Name:</th><th>Last Name:</th><th>Month of Inauguration:</th><th>Year of Inauguration:</th></tr>";
for (var i in data.Presidents) {
output+="<tr><td>" + data.Presidents[i].firstName + "</td><td>" + data.Presidents[i].lastName + "</td><td>" + data.Presidents[i].YearInauguratedPresident.month + "</td><td>" + data.Presidents[i].YearInauguratedPresident.year + "</td></tr>";
}
output+="</tr></table>";
document.getElementById("PresidentInfo").innerHTML=output;
});
</script>

Similar Tutorialshi, I was going through this tutorial: http://www.electrictoolbox.com/json-data-jquery-php-mysql/ here is my HTML Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Untitled Document</title> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script> <script language="javascript" type="text/javascript"> function populateFruitVariety() { $.getJSON('search-by.php', {fruitName:$('#fruitName').val()}, function(data) { var select = $('#fruitVariety'); var options = select.attr('options'); $('option', select).remove(); $.each(data, function(index, array) { options[options.length] = new Option(array['variety']); }); }); } $(document).ready(function() { populateFruitVariety(); $('#fruitName').change(function() { populateFruitVariety(); }); }); </script> </head> <body> <form> Search by: <select name="name" id="fruitName"> <option>Please Select</option> <option id="Town" value="Town">Town</option> <option id="County" value="County">County</option> </select> Variety: <select name="variety" id="fruitVariety"> </select> </form> </body> </html> here is my PHP Code: [Select] $dbhost = "xxx"; $dbname = "xxx"; $dblogin = "xxx"; $dbpass = "xxx"; function dbConnect() { global $dbhost; global $dbname; global $dblogin; global $dbpass; $db = mysql_connect($dbhost, $dblogin, $dbpass) or die("could not connect to database: ".mysql_error()); mysql_select_db($dbname) or die("could not select database"); return $db; } function dbClose($db) { mysql_close($db); } // basis code ^^ $db = dbConnect(); $rows = array(); if(isset($_GET['Town'])) { $query = "SELECT DISTINCT rsCounties FROM pubs"; $result = mysql_query($query) or die(mysql_error()); while($row = mysql_fetch_array($result, MYSQL_ASSOC)) { echo json_encode($rows); } } if(isset($_GET['County'])) { $stmt = $pdo->prepare("SELECT rsCounty FROM pubs"); $stmt->execute(array($_GET['rsCounty'])); $rows = $stmt->fetchAll(PDO::FETCH_ASSOC); } echo json_encode($rows); Can someone please help? I have the JQuery working but not the PHP?! here is a link to what I have at the moment: http://www.mypubspace.com/dashnew/index.html thanks Ok I have a unique issue I have a decent sized database for a fix up and modify project I just landed. My problem is my client has a table with plain html, flash, javascript it in. Which generally speaking isn't to much a problem if I we're going the straight php route to get the data from the database. However I'm not so lucky. These people wish to have the element being built by me to use AJAX to give the site a "2.0" feel, which again to a point fine. So all this said and done, I am going using jQuery as my frame for the javascript. The landing page for the script is PHP it handles any potential user input checks before it works its way into the javascript variables to then use JSON through the javascript to another php file which in turn double checks the inputs just incase someone wants to go in to the source find the way to the file its gathering the data from an all else. Then based on the data forms its output. Which I don't know why Ive wasted my time explaining that, we all know how JSON works in concept at least. My issue with this all is, a single column or 2 but ill stick with just the one for now... with these people having stored plain html, javascript, and object tags for flash in the column without any htmlspecialchars or stripslash's or really any security per say in mind. In other words I can go into any column and just copy and paste the code and have it work in an HTML file as if it were typed out for use in HTML alone. So with that, my JSON requests are failing due to the extra quotes, double quotes, slashes, and all else. What I am trying to figure out is, what is my best method to phrase the output of the DB so its friendly for for the JSON request yet can be repieced back together via javascript/jquery. Any takers on that idea? I have a submit.php file that includes the following jQuery code:
<script> [...] request.done(function( json ) { jQuery('input[name=thumbnail-url]').val(json.thumbnail_url); jQuery('input[name=job_title]').val(json.title); jQuery('textarea[name=htmlcode]').val(json.html); [...] </script>
I need to remove
jQuery('textarea[name=htmlcode]').val(json.html);
and pass the "json.html" value into a PHP variable in another php file (functions.php). The code in the functions.php file is already there. The thing i need to do (and i am seriously struggling with it) is placing the value of json.html into a $phpvariable that i can then call from the function.php file. Do you need any more info for this issue? Thanks. Hello, I can't get a json call to work in my php... Hope some one can see where I am going wrong and push me in the right direction. I have 3 values I am trying to send from the php file to the html. The output looks as if it should work, but is does not... So here is the php variable that does give me a result, but I have no idea why it does not show in the div. <?php $choice = (isset($_POST['choice'])) ? date("Y-m-d",strtotime($_POST['choice'])) : date("Y-m-d"); $con = mysql_connect("localhost","root","xxxxxx"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("inverters", $con); $sql = "SELECT sum(power/1000) AS choice FROM feed WHERE date = '".$choice."' group by date"; $res = mysql_query($sql) or die('sql='.$sql."\n".mysql_error()); $row = mysql_fetch_assoc($res); $dayPowerP = array( $row['choice']); ?> <?php $choice = (isset($_POST['choice'])) ? date("m",strtotime($_POST['choice'])) : date("m"); $con = mysql_connect("localhost","root","xxxxxx"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("inverters", $con); $sql = "SELECT sum(power/1000) AS choice FROM feed WHERE month(date) = '".$choice."'"; $res = mysql_query($sql) or die('sql='.$sql."\n".mysql_error()); $row = mysql_fetch_assoc($res); $monthPowerP = array($row['choice']); ?> <?php $choice = (isset($_POST['choice'])) ? date("Y",strtotime($_POST['choice'])) : date("Y"); $con = mysql_connect("localhost","root","xxxxxx"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("inverters", $con); $sql = "SELECT sum(power/1000) AS choice FROM feed WHERE year(date) = '".$choice."'"; $res = mysql_query($sql) or die('sql='.$sql."\n".mysql_error()); $row = mysql_fetch_assoc($res); $yearPowerP = array( $row['choice']); ?> <?php $outarr['dayPowerP'] = $dayPowerP; $outarr['monthPowerP'] = $monthPowerP; $outarr['yearPowerP'] = $yearPowerP; echo json_encode($outarr); ?> Now there are no errors, and this is what the output is so I would assume it should work as the right values are there and the right id..... Code: [Select] {"dayPowerP":["12.7240"],"monthPowerP":["145.0460"],"yearPowerP":["941.0370"]} I do not understand. Now the Jquery should be working as well... the ajax should be sending the post with json to carry the key data to make a clear result from the php and json should be doing it's job in the php file and the Jquery is do basic to have any issues, so that leaves my focus on the PHP at this time, but I do not see a proplem. Code: [Select] $(document).ready(function () { $('#datepicker').datepicker({maxDate: 0, dateFormat: 'yy-mm-dd', onSelect: function(dateText) { var myDate = $(this).datepicker('getDate'); $('#apDiv1').html($.datepicker.formatDate('DD, d', myDate)); $('#apDiv5').html($.datepicker.formatDate('MM', myDate)); $('#apDiv7').html($.datepicker.formatDate('yy', myDate)); $.ajax({ type: "POST", url: "clickdates.php", data: {choice: dateText}, dataType: "json", success: function(json_data) { $('#apDiv2').html(json_data['dayPowerP']); $('#apDiv6').html(json_data['monthPowerP']); $('#apDiv8').html(json_data['yearPowerP']); } }) }}); }); The one thing that is odd. When I use 3 different php files, it works perfect, but that is not using json. Now that I am using json to return 1 call from the php, I am lost at this point, does anyone see what I can't... Thanks, Alan Hi, I have two select boxes on my site like this: Language - Level and the user can keep adding more sets of select boxes. I need the data posted to be JSON encoded like this: {"LANG1":["German","Beginner"],"LANG2":["Polish","Advanced"]} etc How can i make this happen? Hey guys I am Posting data over to a server file in Json and I need to know how I can add to the XML file. here is both codes.
function validate() {
$xml = simplexml_load_file("stock.xml");
$sxe = new SimpleXMLElement($xml->asXML());
for($i = 1; $i < 801; $i++)
{
$newItem->addChild("name" , "null");
}
$sxe->asXML("stock.xml");
echo $sxe->asXML();
$response = $_POST;
$response["items"] = "Test output";
$response["description"] = "test 42 ";
$response["json"] = json_encode($response);
echo json_encode($response);
}
The red text is what I want this json script to do. Do I have to return back to my form to add to the XML file? Can json add to a xml file on its own? Thanks for your time! have a good day!
how can i also output $pages number into the json as well so i can use it for jquery Code: [Select] <?php // Start Buffer ob_start(); // Load Settings require '../../includes/config.inc.php'; // Require the database connection: require(MYSQL); // Number of records to show per page: $display = 6; // Determine how many pages there are... if (isset($_GET['p']) && is_numeric($_GET['p'])) { // Already been determined. $pages = $_GET['p']; }else{ // Need to determine. // Default Query $count_q = "SELECT COUNT(id) FROM deals"; // Count the number of records: $r = @mysqli_query ($dbc, $count_q); $row = @mysqli_fetch_array ($r, MYSQLI_NUM); $records = $row[0]; // Calculate the number of pages... if ($records > $display) { // More than 1 page. $pages = ceil ($records/$display); } else { $pages = 1; } } // End of p IF. // Determine where in the database to start returning results... if (isset($_GET['s']) && is_numeric($_GET['s'])) { $start = $_GET['s']; } else { $start = 0; } // Make the query: $q = "SELECT id, url, views, deal_img, title, savings, DATE_FORMAT(expiry, '%a, %d %b %Y') AS expr FROM deals ORDER BY created_on DESC LIMIT $start, $display"; $r = @mysqli_query ($dbc, $q); // Run the query. if (mysqli_num_rows($r) > 0) { // Available. /* create one master array of the records */ $offers = array(); while ($offer = mysqli_fetch_array($r, MYSQLI_ASSOC)) { $offers[] = array("id" => $offer["id"], "url" => BASE_APP_URL.'offer/'.$offer["url"].'/', "views" => $offer["views"], "image" => BASE_URL.'niftyuk-deal/'.$offer["deal_img"], "title" => $offer["title"], "savings" => $offer["savings"], "expr" => $offer["expr"]); } // End of WHILE loop. } /* output in necessary format */ header('Content-type: application/json'); echo json_encode($offers); ?> My script is not acting like it should.

The photos you display must not be deceptive, false or misleading any way that infringes on third party intellectual property. You must also not encourage of incentivize other fellow users, friends or business associates to display the same cover image as yours on personal Timelines.<\/p>\r\n<p>To sum up we are extremely excited about the latest Facebook feature release this week.

im trying to access code in Code: [Select] array(1) { [0]=> object(stdClass)#4 (1) { ["error"]=> array(1) { [0]=> object(stdClass)#5 (2) { ["message"]=> string(33) "no results found (error code 458)" ["code"]=> string(3) "458" } } } } ive tryed echo $blog_posts[0]->error->code; but all i get is Notice: Trying to get property of non-object in /home/sites/inspiredanceacademy.com/public_html/sno-blog-test/lib/social_news_office.php on line 173 Okay so i know this is going to sound really stupid i just got out of school and now im in the real world here is the problem I dont know very much about how to work with JSON via PHP all i am trying to do is have the Script read data into an array from some text boxes then from the array into a JSON file the reading and the listing is all fine and dandy but only if i want the entire file how do i read data from a JSON file and only have it display data according to what i want so for example if i wanted to return data that matched an ID like you would do in MySQL like this ("SELECT * FROM catagories WHERE ID = '$id'") so how do i do that without a Database using a JSON File as a source for the data Hi all, I am sure this is simple, but I just can't wrap my head around a suitable way of doing this! Basically I have my JSON result as something like : Code: [Select] Array ( [result] => success [source] => gotBits [success] => 64 ) What I simply want to do is get the [success] output and store it as a variable. I have been looking at json_decode, but I cant find any examples for arrays, just strings? Can you push me in the right direction? I was pointed in this direction by a friend so firstly, hello
I'm having some teething problems (basically can't get my head around it) and wondered if anyone would be able to have a look at a script for me (beer money may be provided)
I'm currently using a php script which grabs information from a API with curl (JSON format). I'm limited to a number of requests an hour so my plan was to read the file, insert the data into a mysql table so that I could re-read over and over again with no limitations. Then use a script to run every few hours to grab the data.
The script I created works however it's a bit buggy with regards to what it does if information is already in the table. If there isn't a previous entry then it inserts everything fine.
The JSON data is a multi depth array, and deals with images as well as data so for me, it's rather complex.
What I want the script to do is this. Each item is a property (letting agent website)
Check to see if the property exists in the database and the JSON. If there is no record in the database, then insert in. If there is a record in the database, update that record. If there is a property in the database which isn't in the JSON file, then delete it from the database.
This is basically the same plan for each sub array (pictures, floorplans, etc) however the images are copied from the url given (hosted on amazon) to my own host in order to speed up loading times, etc.
i've added a copy of the code but obviously its going to be stupidly hard to understand.
Is there any way this could be split into different functions to try and sort it out? haha

Edited by Jam0r, 08 December 2014 - 10:51 AM. Hi, here is my script to get the usernames of a few members. I'm trying to encode it using JSON. Code: [Select] <?php require("connect.php"); $date = date("Y-m-d"); $picarray = array(); $handle = opendir ('pqimages/'.$date.'/'); while (false !== ($file = readdir($handle))) { if($file != "." && $file != "..") { $getusername = mysql_query("SELECT * FROM users WHERE lastupload='pqimages/".$date."/".$file."'"); while ($row = mysql_fetch_assoc($getusername)){ $usernames= $row['username']; $people = array(); $people[] = $usernames; echo json_encode($people); } } } ?> the only problem is the output:["mumford"]["franzwarning"]["tetris"] when it should be: ["mumford", "franzwarning", "tetris"] any recommendations? Thanks, George I'm trying to write a zend restful api and am return a json result. Everything works excepts when I am encoding a very large string such as a article with multiple paragraphs. The result is null in this case. Do I need to do something with the text before performing a json encode. Code: [Select] $this->getResponse() ->appendBody($this->_helper->json($article)); I am writing a simple connector for an android application and my json_encode is outputting enclosing the array with []. This is throwing an error during the decode process because the array needs to start with a {. I know this has to do with the $output[] in the loop, but I dont know how to pass the values into the array any other way. I even tried to trim after doing the encode. Here is my code: Code: [Select] <?php require_once ('includes/config.php'); require_once ('includes/connect.php'); $agency= mysql_query("SELECT agencyname FROM agency WHERE status ='Prospect' ORDER BY agencyname DESC")or die(mysql_error()); while($ageinfo = mysql_fetch_assoc($agency)) { $output[] = $ageinfo; } print(json_encode($output)); ?> help required for noobie(no hair left) all i want to be able to do is use the individual elements of the array in javascript eg companyname or companyimage but just getting my head in my hand. mysql_select_db("herefordinfo") or die(mysql_error()); echo "Connected to Database"; $dbQuery = 'SELECT * FROM companies'; $dbResult = mysql_query($dbQuery) or die ("Could not read data because " . mysql_error()); $RowCount = mysql_numrows($dbResult); while ($pubs = mysql_fetch_assoc($dbResult)) { $array[] = "{ {$pubs['id']}, {$pubs['companyname']}, {$pubs['companyinfo']}, {$pubs['companyimage']} }"; } echo 'var pub = [' . implode(', ', $array) . '];'; // this ?> <html> <head> <script type="text/javascript"> var jsArray = <?php echo json_encode($array); ?>; document.write(jsArray); //this </script> </head> <boby></body> </html> both php and javescritp output the results below { 1, lichfield vaults, 10 church street hereford , lich.jpg },{ 2, Black Lion, bridge street, blacklion.jpg },{ 3, Saracens Head, st martins street, saracens.jpg } im trying to get this ajax function working but for some reason it runs the error function...I've corresponded with the manual and I can't see a fault...any advise would be great...thanks
$(document).ready(function()
{
$.ajax(
{
url: "items.php",
dataType: "json",
data: '<?php echo $data; ?>',
timeout: '2000',
cache: false,
error: function(data)
{
alert('error');
},
success: function(data)
{
$.each(data, function()
{
$("#table").append('<div class="row"><span class="cell">'+ data.title +'</span><span class="cell"></span><span class="cell"></span></div>');
});
}
});
});
