I think I have a simple bug somewhere but I can't see it!
In my view, I have the following javascript to create a form:
$.ajax({
url:"<?php echo site_url('mycontroller/methodX/'.$ip.'/'.$hardwaremodel);?>",
type:'POST',
dataType:'json',
success: function(returnDataFromController) {
var htmlstring;
var submitFormHTML;
htmlstring = "<br><br><B>To reassign the port to a new vlan, click on a VlanId below and then click on the OK button</B><br><table class='table table-bordered table-striped'>";
htmlstring = htmlstring + "<th>VlanId</th><th>Name</th>";
for(i = 0; i < returnDataFromController.length; i++) {
}
submitFormHTML = "<form method='post' accept-charset='utf-8' action='/myapp/index.php/controllerABC/methodABC/"+ $('#ip').val() +"/" + $('#hardwaremodel').val() +"/" + $('#port').val() + "'><input type='text' id='newVlanID' style='width:5em;height:1.5em'/> <button type='submit' class='btn' id='saveVlan' style='width:10em;height:2em'>Reassign Vlan</button></form>";
//alert(submitFormHTML);
$('#clientajaxcontainer').html(htmlstring);
$('#newvlanform').html(submitFormHTML);
It's the "submitFormHTML" string that builds the form.
And in my controller I have the following logic to check for the input:
public function methodABC()
{
if($_POST){
echo 'I am here';
$form = $this->input->post();
var_dump($form);
exit();
}
else {
echo "false";
}
It always print the "false". I've also tried using:
print_r($this->input->post());
and
echo $this->input->post('newID');
But I can't seem to get the data from my view into the controller.
Can you see where I'm going wrong? Thanks for the help.
Edit:
The page when rendered, creates the following HTML for the form:
<form method="post" action="/myapp/index.php/switches/changeportvlan/11.11.11.11 /">
<input type='text' id='newVlanID' style='width:5em;height:1.5em'/>
<button type="submit" class='btn' id='saveVlan' style='width:10em;height:2em'>Reassign Vlan</button>
</form>"
The problem was that the textbox is missing a "name" attribute. "id" is not enough!
You need
if ($this->input->post(Null, False)) {
echo "I am here";
$form = $this->input->post(Null, True); ## True for XSS-cleaning, which you probably want.
exit();
}
else {
echo "False";
}
You have to give $this->input->post() arguments. Moreover, never use $_POST in CodeIgniter.
Good luck

I am using graph API to get access tokken using a reference "pagename?fields=picture" for my facebook page to be used on my website.
This is the function that I am using;
function get_facebook_post_pic_full_url($feed_id)
{
echo "<script>console.log( 'Debug Objects: " . $feed_id . "' );</script>";
$ursls = 'https://graph.facebook.com/'.$feed_id.'/?fields=full_picture,picture&access_token="Access Tokken"';
$fb_act = json_decode(file_get_contents($ursls));
return $fb_act;
}
function get_facebook_page_feed($fts_limiter='')
{
if(!$fts_limiter)
{
$fts_limiter = 1;
}
$pageid = get_field('facebook_page_id','option');
//If there's no Access Token then use a default
$access_token_array = array(
'sampleaccess tokken'
'sampleaccess tokken'
'sampleaccess tokken'
);
$access_token = $access_token_array[rand(0, 11)];
$graph_data = 'https://graph.facebook.com/'.$pageid.'/posts?fields=id,from,message,story,story_tags,link,source,name,caption,description,type,status_type,object_id,attachments,created_time&access_token='.$access_token.'&limit=1&locale=en_US';
$fb_activity = json_decode(file_get_contents($graph_data));
return $fb_activity;
}
And this is used to fetch and display image and caption and date;
<div class="col-xs-12 col-sm-6 col-md-4 no-padding">
<div class="facebook_img">
<?php
$fb_feeds = get_facebook_page_feed();
if(!empty($fb_feeds)):
$feeds = $fb_feeds->data[0];
$created_time = $feeds->created_time;
$link = $feeds->link;
$feed_id = $feeds->id;
$full_arr = get_facebook_post_pic_full_url($feed_id);
$full_picture = $full_arr->full_picture;
$message = $feeds->message;
$submessage = substr($message,0,75);
?>
<!--<?php var_dump($full_arr);?> -->
<img style="width:405px;height:341px" src="<?php echo $full_picture; ?>" alt="facebook"/>
<div class="fb_content"> <a target="_blank" href="<?php echo $link; ?>"><?php echo $submessage; ?></a>
<dt><?php echo date('d/m/Y', strtotime($created_time)); ?></dt>
</div>
<?php endif; ?>
</div>
The issue is that I am getting this error when I run; $ursls = 'https://graph.facebook.com/'.$feed_id.'/?fields=full_picture,picture&access_token="Access Tokken"';
{
"error": {
"message": "(#100) Tried accessing nonexisting field (full_picture) on node type (Page)",
"type": "OAuthException",
"code": 100,
"fbtrace_id": "traceid"
}
}
The code and everything was working fine and it has stopped 2 months ago. Can anyone please tell me why full_picture is nonexisting field? Does that mean that we can not use full_picture parameter for page anymore? Any help is appreciated! :)
The code and everything is working fine and facebook has not changed any parameters that are used in the above post. My access tokken was having some issues, I generated a new one and it started to work now. Thank you!
My business functionality is to format JSON code returned from database and then use AJAX to process the JSON content and need to use only ".getJSON" instead of ".ajax"
The point where i was struck up is: how to sent the parameters using .getJSON to another page (customer.php) as i need to search for the customer data from database and return result in JSON formate.[The "data" parameter which holds key&value pair that needs to be sent to the server.]
Code from ajaxcall.php(where .getJSON is used)
<head>
<script>
$(document).ready(function(){
function search(){
var x=$("#srh").val();
if(x!=""){
$.getJSON({
url:'/customer.php',
data:{value:"x"},
success:function (data)
{
content= data;
$("#result").html(content[0].cust_id);
}
});
}
}
$("#button").click(function(){
search();
});
});
</script>
</head>
<body>
<input type="text" id="srh" placeholder="Enter the Name of the Customer"/>
<input type="button" id="button" value="search" />
<div id="result"></div>
</body>
Here, i need to pass the X parameter to customer.php using getJSON.The way i am passing is not working!
Code from customer.php(where i need to get search term (X parameter as input) $var=$_POST["value"]
and fetch the data from database using X parameter in where condition and return data in JSON content)
<?php
$conn = new mysqli("localhost", "xyz", "12345", "cust");
$var=$_GET['value'];
if (mysqli_connect_errno())
{ echo 'connect not possible to database: ' . mysqli_connect_error($conn); }
else
{
$query="SELECT cust_fname,cust_lname,cust_id,cust_addresa,cust_phone
from customer where UPPER(cust_lname) like UPPER('%" . $x. "%') ";
$result = mysqli_query($conn, $query);
if (!$result) { die("Not Found ! " . mysqli_error($conn)); }
else
{
$rows = mysqli_fetch_all($result, MYSQLI_ASSOC);
$json = json_encode($rows);
}
mysqli_free_result($result);
mysqli_close($conn);
print $json;
}
} ?>
Appreciate your pointer on this! Thanks in Advance.
I am creating new pages for each of my categories in wordpress. The post editor has a custom field that allows the selection of a sector type, this gets applied to the post on update. The custom field key is: sector, for custom field meta value options lets use SectorA, SectorB and SectorC. I am using a custom post type called projects.
I followed the advice at this link http://weblogtoolscollection.com/archives/2008/04/13/how-to-only-retrieve-posts-with-custom-fields/
How can I change the query line in the code below so that it filters the loop by a Sector name, lets use SectorA. I'll then reuse the code on each template page changing the value to SectorB and SectorC on the other pages.
I think this needs changing somehow:
$customPosts->query('showposts=5§or=sectorA&post_type=projects' );
Currently it echos the sector value and description value successfully but is showing all the posts. So my attempt to limit it to sectorA using sector=sectorA doesn't seem to work?
This code is in functions.php:
function get_custom_field_posts_join($join) {
global $wpdb, $customFields;
return $join . " JOIN $wpdb->postmeta postmeta ON (postmeta.post_id = $wpdb->posts.ID and postmeta.meta_key in ($customFields)) ";
}
function get_custom_field_posts_group($group) {
global $wpdb;
$group .= " $wpdb->posts.ID ";
return $group;
}
And this code is on the Template Page:
<?php /* Begin Custom Field Posts */ ?>
<h2>Custom Posts</h2>
<ul>
<?php
global $customFields;
$customFields = "'sector', 'description'";
$customPosts = new WP_Query();
add_filter('posts_join', 'get_custom_field_posts_join');
add_filter('posts_groupby', 'get_custom_field_posts_group');
$customPosts->query('showposts=5§or=sectorA&post_type=projects' );//Uses same parameters as query_posts
remove_filter('posts_join', 'get_custom_field_posts_join');
remove_filter('posts_groupby', 'get_custom_field_posts_group');
while ($customPosts->have_posts()) : $customPosts->the_post();
$sector = get_post_custom_values("sector");
$description= get_post_custom_values("description");?>
<li><?php echo $sector[0]; ?></li>
<li><?php echo $description[0]; ?></li><br />
<?php endwhile; ?>
</ul>
<?php /* End Custom Field Posts */ ?>
Thanks for your help
May be this what you want
function get_custom_field_posts_join($join) {
global $wpdb, $customSector;
return $join . " JOIN $wpdb->postmeta postmeta ON (postmeta.post_id = $wpdb->posts.ID and postmeta.meta_key = 'sector' and postmeta.value = '$customSector') ";
}
and modification of page
$customSector='sectorA';//<--- insert this
add_filter('posts_join', 'get_custom_field_posts_join');
Try using this code.
<?php
$sector = get_post_meta($post->ID, "sector", false);
if ($sector[0]=="") { ?>
<!-- If there are no custom fields, show nothing -->
<?php } else { ?>
<div class="sector">
<h3>Title</h3>
<?php foreach($sector as $sector) {
echo '<blockquote><p>'.$sector.'</p></blockquote>';
} ?>
</div>
<?php } ?>
I've been trying to use the JsPush Zend progress bar in a Zend MVC application, but have not been successful. I've used the JsPush.php example found on github to create a standalone progress bar test application, but this does not use the Zend MVC framework. When I apply the CSS, HTML, JavaScript, and PHP code from the JsPush example program, I see my progress bar appear (the CSS works) but I don't get any results during my socket write process. I've used the JsPush CSS code verbatim in a css file that is linked to my application so I won't repeat that here. Below are exerpts from my MVC application, the controller code:
protected function _sendFile($job)
{
$fp = fopen($job->source_file, "rb");
if($fp == null || $fileData['size'] == 0) {
$this->view->errorMessage = 'Error - file open failed for ' . $job->source_file;
return false;
}
$this->totalXmitSize = $fileSize;
$this->currentXmitSize = 0;
$progressMessage = '';
$adapter = new Zend_ProgressBar_Adapter_JsPush(array
('updateMethodName' => 'Zend_ProgressBar_Update',
'finishMethodName' => 'Zend_ProgressBar_Finish'));
$progressBar = new Zend_ProgressBar($adapter, 0, $this->totalXmitSize);
while(!feof($fp)) {
$blkSize = ($fileSize > 1024) ? 1024 : $fileSize;
$xmitBuf = fread($fp, $blkSize);
if($xmitBuf === false || !strlen($xmitBuf)) {
$this->view->errorMessage = 'Error - file open failed for ' . $job->source_file;
return false;
}
if($this->_writeData($xmitBuf, $blkSize) == false) {
return false;
}
$fileSize -= $blkSize;
$this->currentXmitSize += $blkSize;
$progress = $this->_calculateXmitProgress();
if($progress < 25) {
$progressMessage = 'Just beginning';
} elseif($progress < 50) {
$progressMessage = 'less than half done';
} elseif($progress < 75) {
$progressMessage = 'more than half done';
} else {
$progressMessage = 'almost done';
}
$progressBar->update($this->currentXmitSize, $progressMessage);
if($fileSize <= 0) {
break;
}
}
fclose($fp);
$xmitBuf = '';
$bufLen = 0;
if($this->_readData($xmitBuf, $bufLen) === false) {
return false;
}
$progressBar->finish();
if(strncmp($xmitBuf, MSG_STATUS_OK, strlen(MSG_STATUS_OK)) != 0) {
$this->view->errorMessage = 'Error - invalid response after file transfer complete';
return false;
}
return true;
}
The view code:
<?php
$this->title = "My Title";
$this->headTitle($this->title);
$this->layout()->bodyScripts = 'onload="startProgress();"';
?>
<p class="errors"> <?php echo $this->errorMessage ?> </p >
<?php echo $this->form->setAction($this->url());
?>
<div id="progressbar">
<div class="pg-progressbar">
<div class="pg-progress" id="pg-percent">
<div class="pg-progressstyle"></div>
<div class="pg-invertedtext" id="pg-text-1"></div>
</div>
<div class="pg-text" id="pg-text-2"></div>
</div>
</div>
<div id="progressBar"><div id="progressDone"></div></div>
The layout.phtml code:
function startProgress()
{
var iFrame = document.createElement('iframe');
document.getElementsByTagName('body')[0].appendChild(iFrame);
iFrame.src = 'MyController.php';
}
function Zend_ProgressBar_Update(data)
{
document.getElementById('pg-percent').style.width = data.percent + '%';
document.getElementById('pg-text-1').innerHTML = data.text;
document.getElementById('pg-text-2').innerHTML = data.text;
}
function Zend_ProgressBar_Finish()
{
document.getElementById('pg-percent').style.width = '100%';
document.getElementById('pg-text-1').innerHTML = 'done';
document.getElementById('pg-text-2').innerHTML = 'done';
}
</script>
</head>
<body <?php echo $this->layout()->bodyScripts ?>>
<div>
<h1><?php echo $this->escape($this->title); ?></h1>
<?php echo $this->layout()->content; ?>
</div>
When this runs I get a ton of JavaScript in the page source, but no progress results:
<script type="text/javascript">parent.Zend_ProgressBar_Update({"current":0,"max":3397,"percent":0,"timeTaken":0,"timeRemaining":null,"text":null});</script><br />
<script type="text/javascript">parent.Zend_ProgressBar_Update({"current":1024,"max":3397,"percent":30.14424492199,"timeTaken":0,"timeRemaining":0,"text":"less than half done"});</script><br />
<script type="text/javascript">parent.Zend_ProgressBar_Update({"current":2048,"max":3397,"percent":60.28848984398,"timeTaken":0,"timeRemaining":0,"text":"more than half done"});</script><br />
<script type="text/javascript">parent.Zend_ProgressBar_Update({"current":3072,"max":3397,"percent":90.43273476597,"timeTaken":0,"timeRemaining":0,"text":"almost done"});</script><br />
<script type="text/javascript">parent.Zend_ProgressBar_Update({"current":3397,"max":3397,"percent":100,"timeTaken":0,"timeRemaining":0,"text":"almost done"});</script><br />
<script type="text/javascript">parent.Zend_ProgressBar_Finish();</script><br />
All of this JavaScript pushes my form out of view. I have spent days on the Zend documentation site and scouring the web to find examples of someone successfully using Zend ProgressBar in a MVC framework application, but can not find any working examples. Thanks in advance for any help.
Well I have been successful in getting a JsPush progress bar to work to some degree, but not 100% correct for my application.
The progressbar works, but the form results end up in the hidden iframe. There is no way to get to the submit buttons on that iframe, so my user has to use the back button to get out of the form.
The only way to get the progress bar to work is to use the target attribute in the form and assign it to the name attribute of the iframe. If I don't use the target attribute, the form scrolls for every call to progressBar->update;. So my form results end up on the parent page several hundred lines scrolled down and the scroll bar never works.
I've tried using the example from the Zend documentation, but it doesn't work. This is my first venture into the Zend framework and it has been very frustrating and disappointing. Not a single response to my original question from 28 days ago.
I had same problem. For me it worked since I did the following steps.
Go to the php.ini and check if the following Data is set in your php.ini.
output_buffering = Off
;output_handler =
zlib.output_compression = Off
;zlib.output_handler =
Then go to class Zend_ProgressBar_Adapter_JsPush and find the Method - which is at the bottom - _outputData. Delete everything in this Method and input
// 1024 padding is required for Safari, while 256 padding is required
// for Internet Explorer. The <br /> is required so Safari actually
// executes the <script />
echo str_pad($data . '', 1024, ' ', STR_PAD_RIGHT) . "\n";
echo(str_repeat(' ',256));
if (ob_get_length()){
#ob_flush();
#flush();
#ob_end_flush();
}
#ob_start();
I am struggling with a bit of dojo that is needed to upload a file. Now the file upload form sits within a dojo dialog box, so is hidden until the user selects an 'upload file' button.
This button can be clicked on anywhere on the site, so I've created a controller to handle the upload.
At the moment I am just trying to get it to work, and in my head script I have the following:
<?php $this->headScript()->captureStart(); ?>
function sendForm(){
//Hide the file input field
dojo.style('inputField',"display","none");
//Show the progress bar
dojo.style('progressField',"display","inline");
dojo.byId('preamble').innerHTML = "Uploading ...";
dojo.io.iframe.send({
url: "<?php echo $this->baseUrl(); ?>/fileprocssing/loadfile/",
method: "post",
handleAs: "text",
form: dojo.byId('StartFrm'),
handle: function(data,ioArgs){
var fileData = dojo.fromJson(data);
if (fileData.status == "success"){
//Show the file input field
dojo.style(dojo.byId('inputField'),"display","inline");
dojo.byId('fileInput').value = '';
//Hide the progress bar
dojo.style(dojo.byId('progressField'),"display","none");
dojo.byId('uploadedFiles').innerHTML += "success: File: " + fileData.details.name
+ " size: " + fileData.details.size +"<br>";
dojo.byId('preamble').innerHTML = "File to Upload: ";
}else{
dojo.style(dojo.byId('inputField'),"display","inline");
dojo.style(dojo.byId('progressField'),"display","none");
dojo.byId('preamble').innerHTML = "Error, try again: ";
}
}
});
}
<?php $this->headScript()->captureEnd() ?>
With the the basic upload for like this
<form id="StartFrm" enctype="multipart/form-data"
name="cvupload"
action="<?php echo $this->baseUrl();?>/fileprocssing/loadfile/"
method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="500000">
<!-- wrapping these in spans to be able to modify
parts of this form depending on what the
dojo.io.iframe.submit() does -->
<span id="preamble">File to Upload:</span><br>
<span id="inputField">
<input type="file" id="fileInput" name="uploadFile">
</span>
<span id="progressField" style="display:none;">
<div dojoType="dijit.ProgressBar" style="width:200px" indeterminate="true"></div>
</span>
<br/>
<button value="upload" dojoType="dijit.form.Button"
onclick="sendForm()">Upload</button>
</form>
What I would like to know is how I can get the JSON data object from /fileprocssing/loadfile/ that contains upload data information if the form is called from /somecontroller/someaction/ ?? and when the file has been processed automatically redirect to something like /fileprocesing/reviewdata/
At the moment the action that I have looks like this
public function loadfileAction() {
$log = Zend_Registry::getInstance()->get('log');
$log->log('in loadfileaction', Zend_Log::DEBUG);
$log->log($_FILES['uploadFile']['name'], Zend_Log::DEBUG);
$uploadedFile = array(
'details' => $_FILES['uploadFile'],
'status' => 'success'
);
$log->log($fileUploadData->toJson(), Zend_Log::DEBUG);
$foo = "{'status':'success',details: {name:'".
$_FILES['uploadFile']['name'].
"',size:".
$_FILES['uploadFile']['size'].
"}}";
$log->log($foo, Zend_Log::DEBUG);
$this->view->fileData = $foo;
}
I've handcrafted the JSON data for the time being but will use Zend_Dojo_Data but at the moment I am just trying to get this working.
I have to confess that I don't know dojo that well, but trying to get my head around it in the shortest possible time.
Thanks in advance.
dojo.io.iframe.send requires the response data to be wrapped in a TEXTAREA tag. This is the only/easiest cross browser way to successfully access and load the response data, and is a requirement. It looks like you are sending plain JSON back from the action.
You can also adjust your handleAs to be "json" and skip the intermediate dojo.fromJson(data) call, it will be passed to you as a JSON object (provided the response is wrapped in the aforementioned TEXTAREA)
