I use a mySQL database and have to create some lists in Excel format (xlsx). The Excel sheets must be formated. For csv export I use phpExcel (I know, it is obsolete but still working).
Which add on do I need to create formated Excel sheets from my mySQL database. I use php to create the frontend.
Thanks,
Markus
This is just a copy of the function i use. It just launches the function when a specific $_GET isset. The function creates a xlsx file. If you want to export the file as .csv you can just change the file extension and edit text/xlsm to text/csv
$gg = $db->prepare("SELECT * FROM beta_mails ORDER BY created DESC");
$gg->execute();
$ggg = $gg->get_result();
$gg->store_result();
while ($row = $ggg->fetch_assoc()) {
$data[] = $row;
}
function getprelaunchCSV(){
global $data;
header('Content-Type: text/xlsx; charset=utf-8');
header('Content-Disposition: attachment; filename=data.xlsx');
// create a file pointer connected to the output stream
$output = fopen('php://output', 'w');
// output the column headings
fputcsv($output, array('ID', 'EMAIL', 'OPRETTET'));
foreach ($data as $rowCSV){
fputcsv($output, [$rowCSV["id"], decrypt($rowCSV["email"]), $rowCSV["created"]]);
}
fclose($output);
die();
}
if (isset($_GET["getlist"]) && $_GET["getlist"] == "1") {
echo getprelaunchcsv();
header("Location:admin?success=1");
}
I'm trying to generate a CSV file on the fly, depending on what the user selects as report output. Retrieving the data and writing it to a file using CakeResponse is done, however I'm struggling to set the file extension to '.csv', the file get downloaded as a normal text file.
CakePHP documentation suggests I do this:
$this->response->type('csv');
..but even this is not working, I'm still getting a text file. Can anyone shed some light? Please note, I'm not looking for new methods to generate a CSV file, I just want to change the extension. Thank you.
This is how I download the file:
$this->response->body($this->constructFileBody($logs));
return $this->response;
This is the method 'constructFileBody', although I think its beyond the scope of this question:
public function constructFileBody($logs = array()){
$content = "";
for($i = 0; $i < count($logs); $i++){
$row = $logs[$i]['EventLog'];
$line = $row['description'] . "," . $row['user'] . "," . $row['affected_user'] . "," . $row['report_title'] . "," . $row['date_created'] . "\n";
$content = $content . $line;
}
return $content;
}
As i saw your code, I don't think you used the header anywhere, try this code:
//create a file
$filename = "export_".date("Y.m.d").".csv";
$csv_file = fopen('php://output', 'w');
header('Content-type: application/csv');
header('Content-Disposition: attachment; filename="'.$filename.'"');
$results = $this->ModelName->query($sql); // This is your sql query to pull that data you need exported
//or
$results = $this->ModelName->find('all', array());
// The column headings of your .csv file
$header_row = array("ID", "Received", "Status", "Content", "Name", "Email", "Source", "Created");//columns you want in csv file
fputcsv($csv_file,$header_row,',','"');
// Each iteration of this while loop will be a row in your .csv file where each field corresponds to the heading of the column
foreach($results as $result)
{
// Array indexes correspond to the field names in your db table(s)
$row = array(
$result['ModelName']['id'],
$result['ModelName']['received'],
$result['ModelName']['status'],
$result['ModelName']['content'],
$result['ModelName']['name'],
$result['ModelName']['email'],
$result['ModelName']['source'],
$result['ModelName']['created']
);
fputcsv($csv_file,$row,',','"');
}
fclose($csv_file);
Now look at your code and get the line of code mine which needs to be replaced.
I need to export the results of a MySQL query to an Excel file. I picked up some code to achieve this, but there is one issue. The code sends the header information to the browser with the .xls content type and the query results following the headers. The code for the called page is as follows:
<?php
function cleanData(&$str)
{
$str = preg_replace("/\t/", "\\t", $str);
$str = preg_replace("/\r?\n/", "\\n", $str);
if(strstr($str, '"')) $str = '"' . str_replace('"', '""', $str) . '"';
}
// filename for download
$filename = "customer_inventory_" . date('Ymd') . ".xls";
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Type: application/vnd.ms-excel");
$flag = false;
$query = "SELECT customer_id,sku,qtyoh,date FROM sims_customer_inventory WHERE customer_id=$customer_id and date=(select max(date) from sims_customer_inventory)";
$result = mysql_query($query, $conn) or die(mysql_error());
while(false !== ($row = mysql_fetch_assoc($result))) {
if(!$flag) {
// display field/column names as first row
echo implode("\t", array_keys($row)) . "\r\n";
$flag = true;
}
array_walk($row, 'cleanData');
echo implode("\t", array_values($row)) . "\r\n";
?>
The problem is that when the page is called in this form:
<form action="inventory_download.php" method="get" onsubmit="return validateInventoryform();">
The file does not automatically download. However, when I refresh the page the file downloads. My problem is that when the page is called this should automatically execute the code to download the file. It does not do that. I have looked all over the internet to solve the problem, but I can't find out why it does not work.
This problem is caused by the passing of ajax data to the external page that creates the .xls data. The answer is to turn off the ajax data in the link:
<a href="something.php" data-ajax="false">
That will allow the php code to work properly. There is still the problem that this is not actually a valid Excel file. This code creates a header and follows it with data that is interpreted as an Excel file. It is not an Excel file, but it does open in Excel and then it can be saved as an Excel file. That is an important distinction. If you are in need of an actual Excel file then PHPExcel is what you should use. That is probably the best option.
I want to download a .csv file through link.For that a Download link is defined in a template file.
To generate .csv file I have written a piece of code as follows.
public function loadPartnerApplicantData() {
$inboundBo = BoFactory::getInboundHttpRequestBo();
$fileType = $inboundBo->getSanitizedGetParam('f');
$formId = $inboundBo->getSanitizedGetParam('fid');
ServiceFactory::getFormService()->loadFormDetails($formId);
$dbTable = BoFactory::getFormBo()->getFormDbTable($formId);
$formName = slugify(BoFactory::getFormBo()->getFormName());
$fileName = $formName . "." . time();
$fieldMasterSqlQuery = "SELECT field_name,field_label FROM" . FORM_FIELDS_MASTER_v2 . "where form_id='$formId' order by serial_no";
$fieldMasterSqlQueryStatus = mysql_query(mysql_fetch_assoc($fieldMasterSqlQuery));
$csvHeader = "";
$fieldNameArray = array();
foreach ($fieldMasterSqlQueryStatus as $key => $value) {
if ($value['field_name'] == 'declaration' || $value['field_name'] == 'docPicture') {
continue;
}
$csvHeader.= "\"{$value['field_label']}\";";
$fieldNameArray[] = $value['field_name'];
}
$queryString = implode(",", $fieldNameArray);
$dbTableSqlQuery = "SELECT $queryString FROM `$dbTable`";
$dbTableSqlQueryStaus = mysql_query(mysql_fetch_assoc($dbTableSqlQuery));
ef_clearBuffer();
// To generate csv
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=$fileName.csv");
header("Pragma: no-cache");
header("Expires: 0");
echo($csvHeader);
foreach ($dbTableSqlQueryStaus as $applicantData) {
echo "\n";
foreach ($fieldNameArray as $fieldName) {
echo "\"$applicantData[$fieldName]\";";
}
echo "\n";
}
}
And the required .csv is generated .
But at the end of .csv file HTML tags of the browser is getting displayed. which should not be there.
Please suggest me to remove the html content from the generated .csv file.
Thanks in advance.
Since your function handles the request till the end (i.e., delivers all data), and you don't want the framework (whichever you're using) to continue processing, add
exit(0);
as last line of your function. That will halt the processing after the content is delivered and prevent the framework/environment from sending additional data.
Maybe you already had some echo commands before the header manipulation, then the .csv file which you want to download will contains all strings you have written before.
I have some PHP code that runs a query on a database, saves the results to a csv file, and then allows the user to download the file. The problem is, the csv file contains page HTML around the actual csv content.
I've read all the related questions here already, including this one. Unfortunately my code exists within Joomla, so even if I try to redirect to a page that contains nothing but headers, Joomla automatically surrounds it with its own navigation code. This only happens at the time of download; if I look at the csv file that's saved on the server, it does not contain the HTML.
Can anyone help me out with a way to force a download of the actual csv file as it is on the server, rather than as the browser is editing it to be? I've tried using the header location, like this:
header('Location: ' . $filename);
but it opens the file in the browser, rather than forcing the save dialog.
Here's my current code:
//set dynamic filename
$filename = "customers.csv";
//open file to write csv
$fp = fopen($filename, 'w');
//get all data
$query = "select
c.firstname,c.lastname,c.email as customer_email,
a.email as address_email,c.phone as customer_phone,
a.phone as address_phone,
a.company,a.address1,a.address2,a.city,a.state,a.zip, c.last_signin
from {$dbpre}customers c
left join {$dbpre}customers_addresses a on c.id = a.customer_id order by c.last_signin desc";
$votes = mysql_query($query) or die ("File: " . __FILE__ . "<br />Line: " . __LINE__ . "<p>{$query}<p>" . mysql_error());
$counter = 1;
while ($row = mysql_fetch_array($votes,1)) {
//put header row
if ($counter == 1){
$headerRow = array();
foreach ($row as $key => $val)
$headerRow[] = $key;
fputcsv($fp, $headerRow);
}
//put data row
fputcsv($fp, $row);
$counter++;
}
//close file
fclose($fp);
//redirect to file
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=".$filename);
header("Content-Transfer-Encoding: binary");
readfile($filename);
exit;
EDITS
Full URL looks like this:
http://mysite.com/administrator/index.php?option=com_eimcart&task=customers
with the actual download link looking like this:
http://mysite.com/administrator/index.php?option=com_eimcart&task=customers&subtask=export
MORE EDITS
Here's a shot of the page that the code is on; the generated file still is pulling in the html for the submenu. The code for the selected link (Export as CSV) is now
index.php?option=com_eimcart&task=customers&subtask=export&format=raw
Now here is a screenshot of the generated, saved file:
It shrank during the upload here, but the text highlighted in yellow is the html code for the subnav (list customers, add new customer, export as csv). Here's what my complete code looks like now; if I could just get rid of that last bit of html it would be perfect.
$fp= fopen("php://output", 'w');
$query = "select c.firstname,c.lastname,c.email as customer_email,
a.email as address_email,c.phone as customer_phone,
a.phone as address_phone, a.company, a.address1,
a.address2,a.city,a.state,a.zip,c.last_signin
from {$dbpre}customers c
left join {$dbpre}customers_addresses a on c.id = a.customer_id
order by c.last_signin desc";
$votes = mysql_query($query) or die ("File: " . __FILE__ . "<br />Line: " . __LINE__ . "<p>{$query}<p>" . mysql_error());
$counter = 1;
//redirect to file
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=customers.csv");
header("Content-Transfer-Encoding: binary");
while ($row = mysql_fetch_array($votes,1)) {
//put header row
if ($counter == 1){
$headerRow = array();
foreach ($row as $key => $val)
$headerRow[] = $key;
fputcsv($fp, $headerRow);
}
//put data row
fputcsv($fp, $row);
$counter++;
}
//close file
fclose($fp);
UPDATE FOR BJORN
Here's the code (I think) that worked for me. Use the RAW param in the link that calls the action:
index.php?option=com_eimcart&task=customers&subtask=export&format=raw
Because this was procedural, our link was in a file called customers.php, which looks like this:
switch ($r['subtask']){
case 'add':
case 'edit':
//if the form is submitted then go to validation
include("subnav.php");
if ($r['custFormSubmitted'] == "true")
include("validate.php");
else
include("showForm.php");
break;
case 'delete':
include("subnav.php");
include("process.php");
break;
case 'resetpass':
include("subnav.php");
include("resetpassword");
break;
case 'export':
include("export_csv.php");
break;
default:
include("subnav.php");
include("list.php");
break;
}
So when a user clicked on the link above, the export_csv.php file is automatically included. That file contains all the actual code:
<?
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=customers.csv");
header("Content-Transfer-Encoding: binary");
$fp= fopen("php://output", 'w');
//get all data
$query = "select
c.firstname,c.lastname,c.email as customer_email,
a.email as address_email,c.phone as customer_phone,
a.phone as address_phone,
a.company,a.address1,a.address2,a.city,a.state,a.zip, c.last_signin
from {$dbpre}customers c
left join {$dbpre}customers_addresses a on c.id = a.customer_id order by c.last_signin desc";
$votes = mysql_query($query) or die ("File: " . __FILE__ . "<br />Line: " . __LINE__ . "<p>{$query}<p>" . mysql_error());
$counter = 1;
while ($row = mysql_fetch_array($votes,1)) {
//put header row
if ($counter == 1){
$headerRow = array();
foreach ($row as $key => $val)
$headerRow[] = $key;
fputcsv($fp, $headerRow);
}
//put data row
fputcsv($fp, $row);
$counter++;
}
//close file
fclose($fp);
This is a piece of sample code that I just cooked up to help you out. Use it as an action method in your controller.
function get_csv() {
$file = JPATH_ADMINISTRATOR . DS . 'test.csv';
// Test to ensure that the file exists.
if(!file_exists($file)) die("I'm sorry, the file doesn't seem to exist.");
// Send file headers
header("Content-type: text/csv");
header("Content-Disposition: attachment;filename=test.csv");
// Send the file contents.
readfile($file);
}
This alone will not be enough, because the file you download will still contain the surrounding html. To get rid of it and only receive the csv file's contents you need to add format=raw parameter to your request. In my case the method is inside the com_csvexample component, so the url would be:
/index.php?option=com_csvexample&task=get_csv&format=raw
EDIT
In order to avoid using an intermediate file substitute
//set dynamic filename
$filename = "customers.csv";
//open file to write csv
$fp = fopen($filename, 'w');
with
//open the output stream for writing
//this will allow using fputcsv later in the code
$fp= fopen("php://output", 'w');
Using this method you have to move the code that sends headers before anything is written to the output. You also won't need the call to the readfile function.
Add this method to your controller:
function exportcsv() {
$model = & $this->getModel('export');
$model->exportToCSV();
}
Then add a new model called export.php, code below. You will need to change or extend the code to your situation.

Then go to your default view.php and add a custom buttom, e.g.
// custom export to set raw format for download
$bar = & JToolBar::getInstance('toolbar');
$bar->appendButton( 'Link', 'export', 'Export CSV', 'index.php?option=com_ttvideo&task=export&format=raw' );
Good luck!
You can use Apache's mod_cern_meta to add HTTP headers to static files. Content-Disposition: attachment. The required .htaccess and .meta files can be created by PHP.
Another way to output CSV data in a Joomla application is to create a view using CSV rather than HTML format. That is, create a file as follows:
components/com_mycomp/views/something/view.csv.php
And add content similar to the following:
<?php
// No direct access
defined('_JEXEC') or die;
jimport( 'joomla.application.component.view');
class MyCompViewSomething extends JViewLegacy // Assuming a recent version of Joomla!
{
function display($tpl = null)
{
// Set document properties
$document = &JFactory::getDocument();
$document->setMimeEncoding('text/csv');
JResponse::setHeader('Content-disposition', 'inline; filename="something.csv"', true);
// Output UTF-8 BOM
echo "\xEF\xBB\xBF";
// Output some data
echo "field1, field2, 'abc 123', foo, bar\r\n";
}
}
?>
Then you can create file download links as follows:
/index.php?option=com_mycomp&view=something&format=csv
Now, you would be right to question the 'inline' part in the Content-disposition. If I recall correctly when writing this code some years ago, I had problems with the 'attachment' option. This link which I just googled now seemed familiar as the driver for it: https://dotanything.wordpress.com/2008/05/30/content-disposition-attachment-vs-inline/ . I've been using 'inline' ever since and am still prompted to save the file appropriately from any browsers I test with. I haven't tried using 'attachment' any time recently, so it may work fine now of course (the link there is 7 years old now!)
