I'm trying to generate a csv-file from a database in wordpress.
The generated CSV-file contains the generated database array AND the HTML-sourcecode of the page.
Any idea what a solution could be to get rid of the HTML-Code?
The strategy with ob_start() / ob_end_clean(); seems not to work.
Thanks for your help.
<?php
ob_start();
$filename = 'provider.csv';
$headers = array('ID', 'Name', 'Location');
$handle = fopen('php://memory', 'w');
fputcsv($handle, $headers, ',', '"');
$results = $wpdb->get_results("SELECT * FROM provider");
foreach($results as $results1)
{
$row = array(
$results1->provider_id,
$results1->provider_name,
$results1->provider_location
);
fputcsv($handle, $row, ',', '"');
}
ob_end_clean();
fseek($handle, 0);
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename="' . $filename . '";');
fpassthru($handle);
fclose($handle);
?>

Please use below code I think it will work for you.
<?php
global $wpdb;
$filename = 'provider.csv';
$headers = array('ID', 'Name', 'Location');
$handle = fopen('php://output', 'w');
fputcsv($handle, $headers, ',', '"');
$results = $wpdb->get_results("SELECT * FROM provider");
foreach($results as $results1)
{
$row = array(
$results1->provider_id,
$results1->provider_name,
$results1->provider_location
);
fputcsv($handle, $row, ',', '"');
}
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename="' . $filename . '";');
exit;
?>
Not outputting anything in csv file. Please help!!
This print_r($list).
outputs everything in the database in the right format But when i try to put the into a csv file only one line gets outputted.
$sql = "select * from " . TABLE_ORDERS . "";
$result = $db->Execute($sql);
if ($result->RecordCount() > 0) {
while (!$result->EOF) {
$file_date = date("d_m_Y_G_i_s");
$filename = "../weight/weightExport_".$file_date .".csv";
$customers_Name = $result->fields['customers_name'];
$list = array($customers_Name);
//print_r($list)."<br/>";
$handle = fopen($filename, 'w+');
fputcsv($handle, array('Username'));
fputcsv($handle, $list);
fclose($handle);
$result->MoveNext();
}
}
Change $handle = fopen($filename, 'w+');
to $handle = fopen($filename, 'a+');
It's only one line, because w+ is doing a truncate on that file.
a+ is the append mode.
This is my script:
<?php
ini_set('display_errors',1);

$result = mysql_query('SHOW TABLES');

The only debugging info I get in php are
Notice: Undefined variable: return in /var/www/vhosts/domain.com/httpdocs/scripts_and_crons/internetlead_backup.php on line 38
and
Deprecated: Function ereg_replace() is deprecated in /var/www/vhosts/domain.com/httpdocs/scripts_and_crons/internetlead_backup.php on line 50 x infinity
The only attachment I receive in the email is ATT00001.
echo '<pre>';
echo $return;
echo '</pre>';
Prints out the correct data.
Even doing
echo '<pre>';
echo file_get_contents($backup_file);
echo '</pre>';
Prints out the correct data so the file is being written to but for some reason the script fails at attaching it to the email.
Can't see what could be wrong, any ideas?
Martin
UPDATE
Found the answer in another SO question - PHP mail() attachment problems
That is the correct way to do it.
If your php version is higher than 5.2 you should replace ereg_replace with preg_match and change (“ parts as (“/
I want to export mysql table into pdf format. Please help me
I have tried this code. Here Is my code
My.php
<?php
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("jass12", $con);
$result = mysql_query("SHOW COLUMNS FROM ja");
$i = 0;
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_assoc($result))
{
#$csv_output .='"'.$row['Field'].'","';
$i++;}
}
$csv_output .= "\n";
$values = mysql_query("SELECT * FROM ja");
while ($rowr = mysql_fetch_row($values)) {
for ($j=0;$j<$i;$j++) {
$csv_output .= $rowr[$j].",";
}
$csv_output .= "\n";
}
#$filename = $file."_".date("d-m-Y_H-i",time());
header("Content-type: application/vnd.ms-excel");
header("Content-disposition: xls" . date("Y-m-d") . ".xls");
header( "Content-disposition: filename=".$filename.".xls");
print $csv_output;
exit;
?>
It produces error & also give as output as xls file.
I want to get the exact coding which convert the database file into pdf.
Please help me
try using FPDF http://www.fpdf.org/.
Is there some tool that can store for me the database structure, say in some xml file or something like that.
And later from the code it can generate for me the sql query for this database creation ?
Currently I am working with MySQL , but it probably does not matter .
Just I not want to maintain my self all those things.
In my experience I have used MySQL Workbench to take care of issues like this. If you download Workbench (assuming you don't have it already) from http://wb.mysql.com/ you will have the option to "Create an EER diagram from an existing database." This will create an EER diagram which is a good visual presentation of the database with which you are working. The .mwb file that you can then save can be loaded and then "forward engineered" into local/external database.
Mysqldump is another alternative to use at the command line. It will, by default, dump out the entire schema structure and contained data. However, if you are just looking for database structure including views and routines and you do not care about the data itself then you need to throw some extra parameters into the command.
In my experience Mysqldump is quick and easy whereas EER diagrams are easier to share with others and then forward engineer back onto other DBs from the Workbench application.
EDIT
You should note that just because you export the database create table queries to a .sql file or .mwb file that you can't just copy and paste the text into another platform (Microsoft SQL, Oracle, etc) and expect it to work. Syntax across different versions of SQL is (obviously) different.
THE FOLLOWING ANSWER USES PHP, I am keeping it here for future users.
I wrote code specifically to do that (in PHP):
$db = mysql_connect($dbhost, $dbuser, $dbpass) or die("MySQL Error: " . mysql_error());
mysql_select_db($dbname) or die("MySQL Error: " . mysql_error());
$allTables = Array
(
//put all table names in this array
);
foreach($allTables as $tbl){
define($tbl, $tbl);
}
$clm = '$columns';
$inds = '$indexes';
$query = "SHOW TABLES IN {$dbname}";
$tables = array();
$result = mysql_query($query) or die("ERROR ONE:".mysql_error());
while($row = mysql_fetch_array($result)){
$tables[] = $row["Tables_in_{$dbname}"];
}
//TO GET ARRAY FOR TABLE DISPLAY:
$cols = array();
foreach($tables as $tbl){
// echo "<br/>".
$query = "SHOW COLUMNS FROM $tbl";
$cols[$tbl] = array();
$result = mysql_query($query) or die("ERROR ONE:".mysql_error());
while($row = mysql_fetch_array($result)){
$cols[$tbl][] = array('Field'=>$row['Field'],
'Type'=>$row['Type'],
'Null'=>$row['Null'],
'Default'=>$row['Default'],
'Extra'=>$row['Extra'],
);
}
}
$index = array();
$query = "SELECT * FROM information_schema.statistics

You can export your database with Mysqldump. The web page has all the details on how to use it.
If you want the SQL to create the table, you can use:
SHOW CREATE TABLE tblname
If you have data, foreign keys, stored procedures and views in your database then the MySQL Workbench can forward reverse all that for you.
For MySQL and others, you might want to try the DESCRIBE TABLE.
You might want to look into the mysqldump utility. It will create a copy of your database in SQL format. (Note to avoid a problem I ran into: Be sure to run it with --routines if you want to also capture your stored functions and procedures!)
A typical command would look something like this:
mysqldump --routines -Q --opt -p -u username databasename >savefile.sql
Also, for large databases, these files can get quite large. You might also want to consider gzipping them or otherwise compressing them on the fly, using something like:
mysqldump --routines -Q --opt -p -u username databasename | gzip >savefile.sql.gz
use phpMyAdmin u can export your structure to XML,SQL,CSV and many other by using export option
