Convert excel file to HTML table in Symfony2 - html

I just want to display a Excel file in a twig view with a Symfony2.5 Controller.
With PHPExcel, I can do this trick and it works :
<?php
error_reporting(E_ALL ^ E_NOTICE);
require_once '/../Classes/PHPExcel.php';
$filename = 'filename.xlsx';
$reader = PHPExcel_IOFactory::createReaderForFile($filename);
$excel = $reader->load($filename);
$writer = PHPExcel_IOFactory::createWriter($excel, "HTML");
?>
<html>
<head>
</head>
<style>
<?php
echo $writer->generateStyles(true);
?>
</style>
<body>
<?php
echo $writer->generateSheetData();
?>
</body>
</html>
How can I do the same thing in my Controller in Symfony 2.5 ?
Actually i have this :
public function newAction()
{
$filename = 'filename.xls';
$reader = \PHPExcel_IOFactory::createReaderForFile($filename);
$excel = $reader->load($filename);
$writer = \PHPExcel_IOFactory::createWriter($excel, "HTML");
echo $writer->generateStyles();
echo $writer->generateSheetData();
}
What should i have in my render view ?
Thanks for help !

Real time html editor for download

I like solution in this post Real-Time Html editor with Javascript or editor on this site. Just simple solution without extra functionalities.
How to edit the code to add SAVE/LOAD option? Is there somethin like "downloadable little CMS" to play with HTML/CSS? I want upload it to my hosting, easy access from home/phone/work, I do not want use online services like codepen or Liveweave.
thanks!
EDIT: Due to comments, I will clarify my question. I have some hosting, mySite.com. There is folder with this magic editor, mySite.com/xxx where i have some sample images and some basic css etc.. Im learning html/css, so I developing some basic html temapltes. HTML editor I linked is just fine. Only I need add 3 buttons, NEW/OPEN/SAVE which make new html file/can open it in live editor/and save it. AND I WANT HAVE THIS EASY SOLUTION ON MY OWN HOSTING.
<?php
$fileName = "page.html";
$fileContent = fopen($fileName, "r") or die("Unable to open file!");
if (isset($_POST['text'])) {
file_put_contents($fileName, $_POST["text"]);
}
?>
<!DOCTYPE html><html lang="cs"><head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1">
<style>
.error {background-color: red; color: white;}
</style>
</head><body>
<form method="POST">
<textarea name="text" class="form-control" rows="20" id="pure">
<?php echo fread($fileContent,filesize($fileName)); ?>
</textarea><br>
<input type="submit" value="submit" />
</form>
<hr>
<div id="compiled"></div>
</body>
</html>
<?php
fclose($fileContent);
?>
<script type="text/javascript">
var h = document.getElementById("pure");
var compiled = document.getElementById("compiled");
h.onkeyup = function() {
compiled.innerHTML = h.value;
pure.classList.toggle("error",
compiled.innerHTML !== h.value);
};
h.onkeyup();
</script>
Its my actual work, real-time html editor from link in my question. File "page.html" must exist.
Added func. to load content from "page.html" file into textarea when page loads..
Added button to save textarea content to "page.html" when done..
Probably not perfect code, and for multiple projects must copy into diferent folders and load one by one :( no popup or form to choose diferent filename easily.. but for now it fits my requirements. I can learn/try/work on html template from home/work/mobile on my own hosting without login into third party service.
Ok, I'm done. Here is my final solution.
real-time html editor
Load/save buttons
automatically load files from /projects/ folder into dropdown list
you can upload files to make new project
no need to modify anything, you can just use it.
Index.php
<?php
$fileName = $_POST['project']?? 'index.html';
$fileContent = fopen("./projects/" . $fileName, "r") or die("Unable to open file!");
if (isset($_POST['text'])) {
file_put_contents("./projects/" . $fileName, $_POST["text"]);
}
?>
<!DOCTYPE html><html lang="cs"><head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1">
<style>
.error {background-color:red; color:white;}
.dib {display:inline-block;}
</style>
</head><body>
<?php
echo "<form class='dib' method='POST'><select name='project'>";
$path = './projects/';
$files = scandir($path);
$files = array_diff(scandir($path), array('.', '..'));
foreach($files as $file){
echo "<option" . (($fileName == $file)?' selected':'') . ">" . $file . "</option>";
}
echo "</select> <input type='submit' value='Load!'></form>";
?>
<input type='submit' form='content' value='Save!'>
<form class="dib" style="float:right;" action="fileUploadScript.php" method="post" enctype="multipart/form-data">
Upload a File:
<input type="file" name="the_file" id="fileToUpload">
<input type="submit" name="submit" value="Start Upload">
</form>
<p style='margin:auto; text-align:center; width:20%; text-transform:uppercase; font-weight: bold;'><?php echo $fileName?></p>
<br>
<form id="content" method="POST">
<textarea name="text" rows="40" id="pure" style="width:100%;margin-top:8px;" wrap="off">
<?php echo fread($fileContent,filesize("./projects/" . $fileName)); ?>
</textarea><br>
<input type="hidden" name="project" value="<?php echo $fileName; ?>">
</form>
<hr>
<div id="compiled"></div>
</body>
</html>
<?php
fclose($fileContent);
?>
<script type="text/javascript">
var h = document.getElementById("pure");
var compiled = document.getElementById("compiled");
h.onkeyup = function() {
compiled.innerHTML = h.value;
pure.classList.toggle("error",
compiled.innerHTML !== h.value);
};
h.onkeyup();
</script>
fileUploadScript.php
<?php
$currentDirectory = getcwd();
$uploadDirectory = "/projects/";
$errors = []; // Store errors here
$fileExtensionsAllowed = ['jpeg','jpg','txt','bmp','html','htm','rar','zip','7z','doc','docx','xls','xlsx','ppt','pptx','pdf','pptm','png','gif']; // These will be the only file extensions allowed
$fileNamee = $_FILES['the_file']['name'];
$fileSize = $_FILES['the_file']['size'];
$fileTmpName = $_FILES['the_file']['tmp_name'];
$fileType = $_FILES['the_file']['type'];
$tmp = explode('.',$fileNamee);
$fileExtension = strtolower(end($tmp));
$uploadPath = $currentDirectory . $uploadDirectory . basename($fileNamee);
if (isset($_POST['submit'])) {
if (! in_array($fileExtension,$fileExtensionsAllowed)) {
$errors[] = "This file extension is not allowed. Please upload a JPEG or PNG file";
}
if ($fileSize > 4000000) {
$errors[] = "File exceeds maximum size (4MB)";
}
if (empty($errors)) {
$didUpload = move_uploaded_file($fileTmpName, $uploadPath);
if ($didUpload) {
echo "The file " . basename($fileNamee) . " has been uploaded";
} else {
echo "An error occurred. Please contact the administrator.";
}
} else {
foreach ($errors as $error) {
echo $error . "These are the errors" . "\n";
}
}
}
?>
After you save these two files, dont forget make new folder named "projects" and default file called "index.html" in this folder..

problem with redirect page on Facebook login

I am trying to use Facebook login on my website with inserting Facebook user data on my database.
I have those files as shown below :

$query = "UPDATE Users SET Ffname='$fbfullname', Femail='$femail' where Fuid='$fbid'";
and it is work now

Showing images from path in mysql database

I'm trying to get an understanding of how to retrieve an images from a path stored in mysql database. I have the path as sumple images
Here's the code that I have tried so far.
<?php include 'database.php'; ?>
<!Doctype html>
<html>
<head>
<title>The Image</title>
</head>
<body>
<?php
$sql = 'Select * from images';
$result = mysql_query($sql) or die('Crazy man');
while($row = mysql_fetch_assoc($result))
{
$url = 'http://localhost/image_path/'. $row[image_path];
echo "<img src='$url' height='200' width='200' />";
}
?>
</body>
</html>
Based on your code below
while($row = mysql_fetch_assoc($result))
{
$url = 'http://localhost/image_path/'. $row[image_path];
echo "<img src='$url' height='200' width='200' />";
}
I think you need to change it to something like this
while($row = mysql_fetch_assoc($result))
{
$url = 'image_path/'. $row[image_path];
echo "<img src='$url' height='200' width='200' />";
}
Take note that I removed the http://localhost/
in your $url = 'http://localhost/image_path/'. $row[image_path];
Whenever you try to load images the default directory is automatically loaded so you can just put /image_path/blah-blah directly.

dompdf not creating pdf correctly

I'm using dompdf to try and convert html into a pdf file. The file was created no problem but when I tried to open the file, it was corrupt. When I opened the file in notepad, I could see it was just the raw html. So it hadn't converted anything at all, it had just put it in a file with an extension of pdf.
Here is my code:
include_once '/files/dompdf/dompdf_config.inc.php';
$files = glob("/files/dompdf/include/*.php");
foreach($files as $file) include_once($file);
ob_start();
?>
<!DOCTYPE html>
<html lang="en">
<head>
<title>
Title
</title>
</head>
<body>
<div><p>Hello World</p></div>
</body>
</html>
<?php
$html = ob_get_clean();
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("sample.pdf");
This just grabs the html exactly as it is written here and saves it as sample.pdf but its not a proper pdf file. Am I missing something?
I fixed it by stripping slashes. This is the updated:
$html = ob_get_clean();
if ( get_magic_quotes_gpc() )
$html = stripslashes($html);
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("sample.pdf");

How to escape HTML elements when fetching an array in PHP using Javascript?

I think the problem is in the "aif.php" file"
I am trying to fetch and display an array using PHP but the HTML element <br> is showing up in my result from the following scrip. I know I have to escape the HTML tags but I'm just not sure how! Also, any other advice on this code would be greatly appreciated (i.e. is there any redundancy or areas to improve? Thanks.

Javascript
$('input#grab').on('click', function() {
var name = $('input#name').val();
if ($.trim(name) !='') {
$.post('aif.php', {name: name}, function(data) {
$('div#content').text(data);
});
}
});
If you want to html encode a line like this:
this is <br /> a test
into a line like this:
this is <br /> a test
Use the nifty little function described here: HTML-encoding lost when attribute read from input field
I made a simple error in the Javascript. I wanted to pass back HTML and not TEXT.
With the following change, the PHP is rendered properly:
$('div#content').text(data);
to
$('div#content').html(data);
