PHP - Pdo Output To Json
Hi there, Hoping some one can help. I am new to using PDO and i am trying to get data from my db to json I can get the data down to my $result so i know that part is working, my issue is with encoding it to json, if i pull a single record then it works if i pull all records then it doesn't, an i am not sure why
$result = $page->read($_GET['pageid']);
//check for data
if ($result) {
//page array
$page_arr['pages'] = array();
while ($row =$result->fetch(PDO::FETCH_ASSOC)) {
extract($row);
$page_item = array(
'id'=> $id,
'title' => $title,
'pageid' => $pageid,
'pagecontent' =>html_entity_decode($pagecontent),
'mdkeywords' => $mdkeywords,
'description' =>$description,
'date_added' =>$date_added,
'hasAudio' => $hasAudio,
'excludeSearch' =>$excludeSearch
);
//push to data
array_push($page_arr['pages'], $page_item);
}
//print_r($page_arr['pages']); //If i enable this then i can see all the data
//turn to json
echo json_encode($page_arr['pages'], JSON_FORCE_OBJECT);
//This is where my page is blank.
}
} else {
echo json_encode(array('message'=>'nothing here!.'));
}
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 I am returning the following through JSON: Code: [Select] $this->view->lead_query=$lead_query->fetchALL(); header('OK', true, 200); header('Content-type: application/json'); echo json_encode($this->view->lead_query); I am getting the results in this format: [{"client_name":"Steve Harris","state":"TX"}] Now if the above output was displayed without the square brackets [] I can populate the values in my form correctly. Is there a way i can return the output without the square brackets? I am using multiple levels of JSON data coming into php from a C# application, as in:
return new RootObject() { ID_Project = 4, Name_Project = "Test", Receiver_ID = 4, Receiver_Name = "ABCDE", UserID = 20, UserRole = new User_Role() { ID_User = 20, Role_User = "level 3", User_Role_Description = "U", UserGroup = new List<user_group>() { new User_Group() { ID_UserGroup = 30, Name_UserGroup = "usergroup8", UserID = 20 }, new User_Group() { ID_UserGroup = 31, Name_UserGroup = "usergroup9", UserID = 21 }, new User_Group() { ID_UserGroup = 32, Name_UserGroup = "usergroup10", UserID = 22 } } } }; i am having troubles accessing the second level: UserRole and 3rd level: User_Group in my php script. im currently trying like this: foreach ($phpArray as $key => $value) { echo "<h2>$key</h2>"; foreach ($value as $k => $v) { echo "$k | $v "; foreach ($v as $key1) { echo "$key1 "; } } } does anyone have an idea? Thanks, Revathy Hello all, I have yet again trouble finding a logical solution to my problem. I'm fetching an array which can hold 1 or more values. The problem is, I want these values to ouput in my json_encode function, but this also needs to happen dynamically depending on the amount of values. I can't explain it further, so here's the code so far: Code: (php) [Select] $files = mysql_fetch_array($get_files); $a = count($files); $i = 1; while ($files) { $variablename = 'fileName' . $i; $$variablename = $files['fileName']; $i++; } $output = array( OTHER VALUES , 'fileName1' => $fileName1, 'fileName2' => $fileName2, 'fileName3' => $fileName3, ............); // How do I add the fileNames dynamically depending on how many there are? This got me thinking, I also need to dynamically GET the values with jQuery. How would I do that, when the above eventually works? Thank you. Well I have a script that executes a scan on a system set to run infinitely, and I need it to echo out a message each time it loops through, but I don't want it to echo out the message with the next loop message below it, and the next one below that etc... I've tried using the flush(); function and been messing around with that with no luck. For security reasons I don't want to release any of the processing code, but here is the basic construction of the script: <?PHP ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** $RepeatIt = -1; for($g=1; $g!=$RepeatIt+1; $g++) { ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** $ScanMessage = ":.:.: SCANNING THE HITLIST FOR MOBSTER: ".$MobName." (SCAN #$g) :.:.:"."<br/><br/>"; echo $ScanMessage; ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** } ?> At the moment it's returning: :.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #1) :.:.: :.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #2) :.:.: :.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #3) :.:.: :.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #4) :.:.: So what I want it to do is just delete the scanning message and replace it with the next scan message so while running this script you would see just the number increment on the same line. Any suggestions? Thanks. 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 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!
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? I have some PHP which sends some user provided data to the client:
<?php
header('Content-type: application/json');
$data=array(
array('id'=>10,'firstname'=>'John','lastname'=>'Doe'),
array('id'=>14,'firstname'=>'Jane','lastname'=>'Doe'),
array('id'=>19,'firstname'=>'XSS!','lastname'=>'XSS!'),
);
echo(json_encode($data));
?>
The client then displays the data:
$.getJSON('getJSON.php', {
something: 123
},
function(list) {
var string = '';
for (var i in list) {
string += '<li>< a href = "index.php?id=' + list[i]['id'] + '">' + list[i]['firstname'] + '</a></li>';
}
$("#MyElem").html(string);
});
Does this represent any XSS risk? If so, how do I prevent it?
My script is not acting like it should. I believe its because of the recent change in the api, (the new error array)? Before there was only one.... <?php $gamertag = 'l RaH l'; $url = "http://api.xboxleaders.com/user_api.php?gamertag=".str_replace(' ', '%20', $gamertag); $output = file_get_contents($url); // try to convert the response into a PHP object $obj = json_decode($output); if(!is_object($obj)) die("Error parsing JSON response\n"); //define variables $avatar = ($obj->user->avatar); $gold = ($obj->user->gold); print $avatar; print $gold; ?> if you print_r $object; it displays this {"error":{"code":200,"desc":"OK"}},{"user":{"gold":1,"gamertag":"l RaH l","avatar":"http:\/\/avatar.xboxlive.com\/avatar\/l%20RaH%20l\/avatarpic-l.png","gamerscore":12508,"reputation":20},"recent_games":[{"recent_game":{"title":"Halo: Reach","link":"http:\/\/gamercard.xbox.com\/en-US\/GameCenter\/Achievements?titleId=1297287259&compareTo=l%20RaH%20l","image":"http:\/\/tiles.xbox.com\/tiles\/ih\/ew\/0Wdsb2JhbA9ECgR8GgMfVlohL2ljb24vMC84MDAwIAAAAAAAAP6fF5U=.jpg"}},{"recent_game":{"title":"Halo 3","link":"http:\/\/gamercard.xbox.com\/en-US\/GameCenter\/Achievements?titleId=1297287142&compareTo=l%20RaH%20l","image":"http:\/\/tiles.xbox.com\/tiles\/Us\/3e\/1Wdsb2JhbA9ECgR8GgMfWSpVL2ljb24vMC84MDAwIAAAAAAAAPrxzU0=.jpg"}},{"recent_game":{"title":"AC Brotherhood","link":"http:\/\/gamercard.xbox.com\/en-US\/GameCenter\/Achievements?titleId=1431504989&compareTo=l%20RaH%20l","image":"http:\/\/tiles.xbox.com\/tiles\/oK\/tp\/1Wdsb2JhbA9ECgUNGgMfVlonL2ljb24vMC84MDAwIAAAAAAAAPpGq78=.jpg"}},{"recent_game":{"title":"Fighters Uncaged","link":"http:\/\/gamercard.xbox.com\/en-US\/GameCenter\/Achievements?titleId=1431504974&compareTo=l%20RaH%20l","image":"http:\/\/tiles.xbox.com\/tiles\/v+\/Au\/0Wdsb2JhbA9ECgUNGgMfVlsmL2ljb24vMC84MDAwIAAAAAAAAP4B4KA=.jpg"}},{"recent_game":{"title":"Assassin's Creed","link":"http:\/\/gamercard.xbox.com\/en-US\/GameCenter\/Achievements?titleId=1431504852&compareTo=l%20RaH%20l","image":"http:\/\/tiles.xbox.com\/tiles\/L3\/mu\/0Wdsb2JhbA9ECgUNGgMfWStXL2ljb24vMC84MDAwIAAAAAAAAP6BeTA=.jpg"}}]} 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); ?> 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...

Facebook itself recommends using a photo of a popular menu item, album artwork or an image of your product being used by someone. You need to experiment with a number of different images that your audience responds positively to. Few key elements of Cover Images:<\/p>\r\n<p><strong>Each Cover image must be at least 399 pixels wide and must not contain the following:<\/strong><\/p>\r\n<ul>\r\n<li>Prices \/ Purchase information and displaying offers such as \"60% off this month\" are not permitted. Also 'Download this from our website' is not allowed.<\/li>\r\n<li>No email addresses, web addresses and any other contact information.<\/li>\r\n<li>References to clicking on or the use of Facebook interface elements such as Like or Share or any other Facebook Features.<\/li>\r\n<li>\"Tell your friends\" or \"Get it now\" or any other calls to action are not allowed in the latest version of Facebook Timeline.<\/li>\r\n<\/ul>\r\n<p>All Timeline cover imagery is public and therefore means anyone visiting your Page will be able to see exactly which image you have chosen. 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.

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.

There are two nice script which are advanced for me to understand. There is a Knockout tournament scheduler class that makes image of the bracket. and there is a code that makes html of the bracket with jquery. I want to use the class with jquery. but I don't know how to do that and where to start. the class below needs to implement to this http://whileonefork.blogspot.com/2010/10/jquery-json-to-draw-elimination-single.html I attached the php script. please help me!

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)); ?> 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? Hello, I am trying to understand how to post several actions and return 1 call. I am new to this so I thank you for your understanding. Here is the full story, I have the Jquery working now that 1 "onSelect" will post to 6 php files, but it takes forever for all the calls to return to the div. From my reading, I need to put the 6 php files into one php file, and then return this with JSON... here is where my trouble begins. Now here is the current php file that I have put into 1 php file (placed as they were working when in 6 files to the Jquery below) <?php $choice = (isset($_POST['choice'])) ? date("Y-m-d",strtotime($_POST['choice'])) : date("Y-m-d"); $con = mysql_connect("xxxxxx","xxxxxx","xxxxxx"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("inverters", $con); $sql = "SELECT sum(power/1000) AS choice FROM feed WHERE date = '".$dayPower."' group by date";$res = mysql_query($sql) or die('sql='.$sql."\n".mysql_error()); $d = array(); while($row = mysql_fetch_assoc($res)) {; echo json_encode($d); } ?> <?php $choice = (isset($_POST['choice'])) ? date("Y-m-d",strtotime($_POST['choice'])) : date("Y-m-d"); $con =$con = mysql_connect("xxxxxx","xxxxxx","xxxxxx"); mysql_connect("localhost","root","mackie1604"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("inverters", $con); $sql = " SELECT HOUR(time) as h, power FROM feed WHERE date = '".$choice."'

How do I get JSON to send and return from the one PHP file. Thank You, Alan |
