A user accesses the Calculation.html first and enters two numbers following message. Then, select the operation from the drop-down box. When the user clicks the button, the web page displays the correct result by sending the data to the PHP file for evaluating the result. I have the PHP code here and whenever I run the code I keep getting an error.
<!doctype html>

esleif( $operator == 'subtract') {

I have had issues with this until now.
What you want is to check your .env file and make sure your database parameters are right, but also you want these:
CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync
For some reason I got these to have empty fields. And then it worked for me!
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.
So im getting a blank page when loading this page within an iFrame on Internet explorer, every other browser works fine..
I have also tried using p3p headers as other people have suggested, but to no avail.

You're probably missing p3p headers causing your browser not to accept cookies from Facebook on your site.
See http://www.hanselman.com/blog/TheImportanceOfP3PAndACompactPrivacyPolicy.aspx
or http://www.admon.org/how-to-implement-p3p-http-headers-for-cross-site-cookies/ for more information.
Try removing the line that references your external css file and see if your page loads?
I just solved a similar problem I had. I had the correct p3p headers set up and I narrowed the problem down to css.
The problematic css style was a position:relative; on the html,body element - removing this fixed the problem of Facebook showing my iframe as a blank page.
If removing all the CSS displays something on your page, then you may need to add your CSS step-by-step to find out the culprit as some other kind of css sytle may break the page.
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'm trying to keep track of some custom behaviour on our Facebook Canvas App. I need to send custom variables to Google Analytics but the fb:google-analytics tag is too limited.
Do you know a way of working around this?
I'm tracking the normal page view but I also need to track Ajax calls and custom variables.
Thanks,
Diogo
Ok, based on Denis suggestion but considering the fact we can't completely switch our App to run as an iFrame, we fixed the problem using 'invisible' iFrames in the beginning of the page.
The code is very similar to this:
<?php
$variable = $_GET[ 'var' ];
$value = $_GET[ 'value' ];
$slot = array_key_exists( 'slot', $_GET ) ? $_GET[ 'slot' ] : 1;
$level = array_key_exists( 'level', $_GET ) ? $_GET[ 'level' ] : 3;
if ( empty( $variable ) || empty( $value ) )
{
$variable = 'BadRequest';
$value = '1';
$slot = 1;
$level = 3;
}
assert( 'is_string( $variable )' );
assert( 'is_numeric( $slot )' );
assert( 'is_numeric( $level )' );
$customParamStr = "'$slot', '$variable', '$value', '$level'";
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<head>
<title>Analytics Frame</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript">
var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-XXXXXXXX-X']);
_gaq.push(['_setCustomVar', <?php echo $customParamStr ?>]);
_gaq.push(['_trackPageview']);
(function() {
var ga = document.createElement('script');
ga.type = 'text/javascript';
ga.async = true;
ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
var s = document.getElementsByTagName('script')[0];
s.parentNode.insertBefore(ga, s);
})();
</script>
</head>
<body>
</body>
</html>
And to use it, we add this iFrame to a canvas page using:
<iframe class="analyticsFrame" id="analyticsCode"
src="???/analyticsFrame.php?var=varname&value=valuename&slot=1&level=3" ?>" width="0px" height="0px" />
We still have to improve the code, for example, we could add support for multiple variables in the same iFrame...
I hope this helps someone and I hope we'll be able to switch totally to iFrame very soon :)
p.s. You can use this technique to run pretty much any javascript but keep in mind that, if you need it a lot, you should project switch completely to iFrame right now :)
Thanks for your help once more :)
Cheers,
Diogo
