I am trying to query a mysql database and display data in a table.I now want to take the table and make a button that allows you to export it to an excel file.now you were able to export to excel,but its showing an error Notice: Undefined variable: data
Below is my code:
<?php
$mysql_hostname = "localhost";
$mysql_user = "root";
$mysql_password = "";
$mysql_database = "export";
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Could not connect database");
mysql_select_db($mysql_database, $bd) or die("Could not select database");
$values =mysql_query( "SELECT name,email,phone,nationality,dob FROM users order by id");
$header = "Name" . "\t";
$header .= "Email" . "\t";
$header .= "Phone" . "\t";
$header .= "Nationality" . "\t";
$header .= "DOB" . "\t";
while( $row = mysql_fetch_assoc($values)){
$row1 = array();
$row1[] = $row['name'];
$row1[] = $row['email'];
$row1[] = $row['phone'];
$row1[] = $row['nationality'];
$row1[] = $row['dob'];
$data .= join("\t", $row1)."\n";
}
header("Content-type: application/x-msdownload");
header("Content-Disposition: attachment; filename=expot.xls");
header("Pragma: no-cache");
header("Expires: 0");
print "$header\n$data";
exit();
?>
Because you never initialize the $data variable.
Put:
$data = '';
at the beginning of your code, before the while cycle.
Your code contains the statement:
$data .= join("\t", $row1)."\n";
This is where you're concatenating a string to an existing variable $data. However, no such variable exists. You should add somewhere near the top of your code:
$data = "";
to initialize the $data variable.

I have an php script, which i want to use to automatically export data from a certain mysql table, to a CSV file in a directory. The script is working fine and the files are saved in the right directory, but u want, that every order, exports to a separate CSV file.
Like:
12-09-2016-05-21_csvexport_1.CSV < data from order 1
12-09-2016-05-21_csvexport_2.CSV < data from order 2
And so on..
I want to run the script automatically with a cronjob. The orders to be exported as a separate csv file, can be selected with a date range. Like only create csv files from the last 2 days. It doesn't matter if the CSV files are going to overwrite.
The order table looks like this:
id_order date customer
1 01-01-2016 1223
2 01-02-2016 1224
3 01-03-2016 1225
4 01-04-2016 1226
5 01-05-2016 1227
And the php script looks like this:
<?php
error_reporting(E_ALL ^ E_DEPRECATED);
$host = 'localhost';
$user = 'user';
$pass = 'pass';
$db = 'database';
$table = 'columns';
$file = 'csvexport';
$dir = 'csv';
$link = mysql_connect($host, $user, $pass) or die("Can not connect." . mysql_error());
mysql_select_db($db) or die("Can not connect.");
function escape_csv_value($value) {
$value = str_replace('"', '""', $value);
if ( preg_match( '/\\r|\\n|,|"/', $value ) ) {
return '"' . str_replace( '"', '""', $value ) . '"';
} else {
return $value;
}
}
$result = mysql_query("SHOW COLUMNS FROM ".$table."");
$i = 0;
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_assoc($result)) {
$csv_output .= $row['Field']."; ";
$i++;
}
}
$values = mysql_query("SELECT id_order, date, customer FROM orders");
while ($rowr = mysql_fetch_row($values)) {
for ($j=0;$j<$i;$j++) {
$csv_output .= escape_csv_value($rowr[$j]).';';
}
$csv_output .= "\n";
}
header("Content-type: application/vnd.ms-excel");
header("Content-disposition: csv" . date("Y-m-d") . ".csv");
header( "Content-disposition: attachment; filename=".$filename.".csv");
$filename = date("d-m-Y-i-s_", time()) . $file.".csv";
print $csv_output;
file_put_contents($dir ."/".$filename, $csv_output);
}
?>
I hope someone can help me. Thanks in advance.
I created the file using PHPExcel at say C:\path\goes\here\filename.xls
When I try to access it using header(), it creates a file filename(1) , filename(2) and so on.
(PS : When i say overwrite, I mean to erase previous content and add new data).
<?php
include 'PHPExcel.php';

Hi write your filename in header function using this
header('Content-Disposition: attachment; filename="filename.xls"');
you can use php basename() function to get the file names at that specific path and then check if the file you are creating already exists.
if it already exists then delete the old file and create the new file.
https://www.w3schools.com/php/func_filesystem_basename.asp
and this should be done before you call header("Content-Disposition: attachment; filename=$filename");
I am trying to bug fix a PHP script that should export values from a MySQL database to a CSV file.
The PHP file is returning a blank CSV file & I can't figure out why & I've been stuck on this for quite a while, so any help would be much apprwciated.
Code below:
<?
include('../../../inc/config.php');
$period = $_GET['pid'];
$psql = "SELECT month, year FROM survey_period WHERE sid = " . $period;
$pres = mysql_query($psql, $dcon);
$prow = mysql_fetch_array($pres);
$pmonth = $prow['month'];
$pyear = $prow['year'];
$query="SELECT
sid,
date,
stove_id,
name,
gender,
marital_status,
occupation_of_household,
cz_stove AS km_stove,
happy_with_cz_stove AS happy_with_km_stove,
cz_stove_in_use AS km_stove_in_use,
know_how_to_use,
FROM survey_usage WHERE period = " . $_GET['pid'];
$result = mysql_query($query, $dcon);
//header('Content-Disposition: attachment;filename=export.csv');
$filename = 'usage-'.$pid.'-'.$pmonth.'-'.$pyear;
header('Content-Type: text/csv');
header("Content-disposition: csv" . date("Y-m-d") . ".csv");
header( "Content-disposition: filename=".$filename.".csv");
$row = mysql_fetch_assoc($result);
if ($row) {
echocsv(array($title));
echo "\r\n";
echocsv(array_keys($row));
}
while ($row) {
echocsv($row);
$row = mysql_fetch_assoc($result);
}
function echocsv($fields)
{
$separator = '';
foreach ($fields as $field) {
if (preg_match('/\\r|\\n|,|"/', $field)) {
$field = '"' . str_replace('"', '""', $field) . '"';
}
echo $separator . $field;
$separator = ',';
}
echo "\r\n";
}

hey i have a code you can use it like this
<?PHP
// Define database connection variable dynamically
$DB_Server = "localhost"; //MySQL Server
$DB_Username = "root"; //MySQL Username
$DB_Password = ""; //MySQL Password
$DB_DBName = "test1"; //MySQL Database Name
$DB_TBLName = "tabletest"; //MySQL Table Name
$filename = "excelfilename"; //File Name
//create MySQL connection
$sql = "Select * from csvtable";
$Connect = #mysqli_connect($DB_Server, $DB_Username, $DB_Password) or die("Couldn't connect to MySQL:<br>" . mysqli_error() );
//select database
$Db = #mysqli_select_db( $Connect,$DB_DBName) or die("Couldn't select database:<br>" . mysqli_error() );
//execute query
$result = #mysqli_query( $Connect,$sql) or die("Couldn't execute query:<br>" . mysqli_error() );
function cleanData(&$str)
{
if ($str == 't')
$str = 'TRUE';
if ($str == 'f')
$str = 'FALSE';
if (preg_match("/^0/", $str) || preg_match("/^\+?\d{8,}$/", $str) || preg_match("/^\d{4}.\d{1,2}.\d{1,2}/", $str)) {
$str = "'$str";
}
if (strstr($str, '"'))
$str = '"' . str_replace('"', '""', $str) . '"';
}
// filename for download
$filename = "file_" . date('Ymd') . ".csv";
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Type: text/csv;");
$out = fopen("php://output", 'w');
$flag = false;
while ($row = mysqli_fetch_assoc($result))
{
if (!$flag)
{
// display field/column names as first row
fputcsv($out, array_keys($row), ',', '"'); $flag = true;
}
array_walk($row, 'cleanData');
// insert data into database from here
fputcsv($out, array_values($row), ',', '"');
}
fclose($out);
exit;
//end
?>
The issue is that you are not writing anything to the csv file before opening it.
Use this code
$fp = fopen($filename, 'w');
$result = mysql_query($query);
$num_fields = mysql_num_fields($result);
$headers = array();
for ($i = 0; $i < $num_fields; $i++) {
$headers[] = mysql_field_name($result , $i);
}
fputcsv($fp, $headers);
while($row = mysql_fetch_assoc($result)) {
fputcsv($fp, $row);
}
fclose($fp);
header('Content-Type: text/csv');
header( "Content-disposition: filename=".$filename);
readfile($filename);
Thanks to everyone for your suggestions, problem now solved, turned out to be a simple comma in the wrong place - "know_how_to_use," changed to " know_how_to_use" solved the problem. Thanks #Tintu C Raju for pointing me in the right direction
I'm trying to get my MySQL data to Excel file, but I'm having problems with Excel cells. All my text goes to one cell, I would like to have each row value in separate Excel cell. Here is my code:
$queryexport = ("
SELECT username,password,fullname FROM ecustomer_users
WHERE fk_customer='".$fk_customer."'
");
$row = mysql_fetch_assoc($queryexport);
$result = mysql_query($queryexport);
$header = '';
for ($i = 0; $i < $count; $i++){
$header .= mysql_field_name($result, $i)."\t";
}
while($row = mysql_fetch_row($result)){
$line = '';
foreach($row as $value){
if(!isset($value) || $value == ""){
$value = "\t";
}else{
$value = str_replace('"', '""', $value);
$value = '"' . $value . '"' . "\t";
}
$line .= $value;
}
$data .= trim($line)."\n";
$data = str_replace("\r", "", $data);
if ($data == "") {
$data = "\nno matching records found\n";
}
}
header("Content-type: application/vnd.ms-excel; name='excel'");
header("Content-Disposition: attachment; filename=exportfile.xls");
header("Pragma: no-cache");
header("Expires: 0");
// output data
echo $header."\n".$data;
mysql_close($conn);`
Just Try With The Following :
PHP Part :
<?php

I think this may help you to resolve your problem.
Try this code. It's definitly working.
<?php
// Connection
$conn=mysql_connect('localhost','root','');
$db=mysql_select_db('excel',$conn);
$filename = "Webinfopen.xls"; // File Name
// Download file
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Type: application/vnd.ms-excel");
$user_query = mysql_query('select name,work from info');
// Write data to file
$flag = false;
while ($row = mysql_fetch_assoc($user_query)) {
if (!$flag) {
// display field/column names as first row
echo implode("\t", array_keys($row)) . "\r\n";
$flag = true;
}
echo implode("\t", array_values($row)) . "\r\n";
}
?>
If you just want your query data dumped into excel I have to do this frequently and using an html table is a very simple method. I use mysqli for db queries and the following code for exports to excel:
header("Content-Type: application/xls");
header("Content-Disposition: attachment; filename=filename.xls");
header("Pragma: no-cache");
header("Expires: 0");
echo '<table border="1">';
//make the column headers what you want in whatever order you want
echo '<tr><th>Field Name 1</th><th>Field Name 2</th><th>Field Name 3</th></tr>';
//loop the query data to the table in same order as the headers
while ($row = mysqli_fetch_assoc($result)){
echo "<tr><td>".$row['field1']."</td><td>".$row['field2']."</td><td>".$row['field3']."</td></tr>";
}
echo '</table>';
This is new version of php code
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "your_dbname";
//mysql and db connection
$con = new mysqli($servername, $username, $password, $dbname);
if ($con->connect_error) { //error check
die("Connection failed: " . $con->connect_error);
}
else
{
}
$DB_TBLName = "your_table_name";
$filename = "excelfilename"; //your_file_name
$file_ending = "xls"; //file_extention
header("Content-Type: application/xls");
header("Content-Disposition: attachment; filename=$filename.'.'.$file_ending");
header("Pragma: no-cache");
header("Expires: 0");
$sep = "\t";
$sql="SELECT * FROM $DB_TBLName";
$resultt = $con->query($sql);
while ($property = mysqli_fetch_field($resultt)) { //fetch table field name
echo $property->name."\t";
}
print("\n");
while($row = mysqli_fetch_row($resultt)) //fetch_table_data
{
$schema_insert = "";
for($j=0; $j< mysqli_num_fields($resultt);$j++)
{
if(!isset($row[$j]))
$schema_insert .= "NULL".$sep;
elseif ($row[$j] != "")
$schema_insert .= "$row[$j]".$sep;
else
$schema_insert .= "".$sep;
}
$schema_insert = str_replace($sep."$", "", $schema_insert);
$schema_insert = preg_replace("/\r\n|\n\r|\n|\r/", " ", $schema_insert);
$schema_insert .= "\t";
print(trim($schema_insert));
print "\n";
}

Posts by John Peter and Dileep kurahe helped me to develop what I consider as being a simpler and cleaner solution, just in case anyone else is still looking. (I am not showing any database code because I actually used a $_SESSION variable.)
The above solutions invariably caused an error upon loading in Excel, about the extension not matching the formatting type. And some of these solutions create a spreadsheet with the data across the page in columns where it would be more traditional to have column headings and list the data down the rows. So here is my simple solution:
$filename = "webreport.csv";
header("Content-Type: application/xls");
header("Content-Disposition: attachment; filename=$filename");
header("Pragma: no-cache");
header("Expires: 0");
foreach($results as $x => $x_value){
echo '"'.$x.'",' . '"'.$x_value.'"' . "\r\n";
}
Change to .csv (which Excel instantly updates to .xls and there is no error upon loading.)
Use the comma as delimiter.
Double quote the Key and Value to escape any commas in the data.
I also prepended column headers to $results so the spreadsheet looked even nicer.
Try the Following Code Please.
just only update two values.
1.your_database_name
2.table_name
<?php
$host="localhost";
$username="root";
$password="";
$dbname="your_database_name";
$con = new mysqli($host, $username, $password,$dbname);
$sql_data="select * from table_name";
$result_data=$con->query($sql_data);
$results=array();
filename = "Webinfopen.xls"; // File Name
// Download file
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Type: application/vnd.ms-excel");
$flag = false;
while ($row = mysqli_fetch_assoc($result_data)) {
if (!$flag) {
// display field/column names as first row
echo implode("\t", array_keys($row)) . "\r\n";
$flag = true;
}
echo implode("\t", array_values($row)) . "\r\n";
}
?>
This is baes on John Peter's answer above. The code is working perfectly but I needed it for WordPress. So, I did something like this:
<?php

$file_name = "registered-users";
$args = array( 'role' => 'client',
'meta_query' => array( array(
'key' => '_dt_transaction_archived',
'compare' => 'NOT EXISTS'
) ),
'order' => 'DESC',
'orderby' => 'ID'
);
$users = get_users( $args );
$file_ending = "xls";
// Header info for browser
header( "Content-Type: application/xls" );
header( "Content-Disposition: attachment; filename=$file_name.$file_ending" );
header( "Pragma: no-cache" );
header( "Expires: 0" );
/*******Start of Formatting for Excel*******/

$sep = "\t"; //tabbed character
// start of printing column names as names of MySQL fields
print( "First Name" . $sep );
print( "Last Name" . $sep );
print( "E-Mail" . $sep );
print( "\n" );
// end of printing column names
// start foreach loop to get data
$schema_insert = "";
foreach ($users as $user) {
if ( $user ) {
$schema_insert = "$user->first_name" . $sep;
$schema_insert .= "$user->last_name" . $sep;
$schema_insert .= "$user->user_email" . $sep;
print "\n";
$schema_insert = str_replace( $sep . "$", "", $schema_insert );
$schema_insert = preg_replace( "/\r\n|\n\r|\n|\r/", " ", $schema_insert );
$schema_insert .= "\t";
print( trim( $schema_insert ) );
}
}
I am attempting to add a function that will create a csv for download from a certain table in the db. I have got it partially working but cannot figure out how to exclude certain columns from the rows section of the csv. Here is my code so far,
$host = 'xxx';
$user = 'xxxx';
$pass = 'xxxx';
$db = 'xxxx';
$table = 'headers';
$file = 'export';
$filename = $file."_".date("Y-m-d_H-i",time());
header("Content-type: application/vnd.ms-excel");
header("Content-disposition: csv" . date("Y-m-d") . ".csv");
header( "Content-disposition: filename=".$filename.".csv");
$link = mysql_connect($host, $user, $pass) or die("Can not connect." . mysql_error());
mysql_select_db($db) or die("Can not connect.");
$result = mysql_query("SHOW COLUMNS FROM ".$table." WHERE Field NOT IN ('invhead_id', 'note');");
$i = 0;
if (mysql_num_rows($result) > 0)
{
while ($row = mysql_fetch_assoc($result))
{
$csv_output .= $row['Field'].", ";
$i++;
}
}
$csv_output .= "\n";
$values = mysql_query("SELECT * FROM ".$table."");
while ($rowr = mysql_fetch_row($values))
{
for ($j=0;$j<$i;$j++)
{
$csv_output .= $rowr[$j].", ";
}
$csv_output .= "\n";
}
print $csv_output;
exit;
I have excluded the columns invhead_id and note from the $result output but also need to exlude them from the $values output as well however this is the bit I cannot get to work. Can anyone point me in the right direction?
Thanks
The easiest way is to select your columns by name instead of select *
There is no easier way, but you could also write a php function that compares your two arrays and discards the ones you don't want based on the first array and....you should just use my first idea.
SELECT field1, field2, field7 FROM table
