I'm exprting my databse in csv format, but I can't figure out how to export the mysql table columns names as well. Here is the code:
public function save($query)
{
$stmt = $this->db->prepare($query);
$stmt->execute();
/* header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");
var_dump($stmt->fetch(PDO::FETCH_ASSOC));
$data = fopen('/tmp/db_user_export_".time().".csv', 'w');
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){
echo "Success";
fputcsv($data, $row);
} */
$list = array ();
// Append results to array
array_push($list, array("## START OF USER TABLE ##"));
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
array_push($list, array_values($row));
}
array_push($list, array("## END OF USER TABLE ##"));
// Output array into CSV file
$fp = fopen('php://output', 'w');
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="file.csv"');
foreach ($list as $ferow) {
fputcsv($fp, $ferow);
}
}
for the query:
include_once 'dbconfig.php';
$query = "SELECT * FROM users";
$crud->save($query);
The file.csv exports correctly but I would like to also include the names of the mysql table columns from where the values are being taken out from.
Thanks in advance!
I was having issues posting my table head into the csv so I took another approach. Hope it helps anyone that's trying to do what I'm doing:
public function export($table)
{
$stmt2 = $this->db->prepare("DESCRIBE ".$table);
$stmt2->execute();
if ($stmt2->rowCount()>0) {
while ($row = $stmt2->fetch(PDO::FETCH_ASSOC)) {
$csv_output .= $row['Field'].", ";
$i++;
}
}
$csv_output .= "\n";
$stmt3 = $this->db->prepare("SELECT * FROM ".$table);
$stmt3->execute();
while ($rowr = $stmt3->fetch(PDO::FETCH_BOTH)) {
for ($j=0;$j<$i;$j++) {
$csv_output .= $rowr[$j].", ";
}
$csv_output .= "\n";
}
$filename = "raport_proiecte_".date("Y-m-d_H-i",time()).".csv";
header("Content-Type: application/xls");
header("Content-Disposition: attachment; filename=$filename");
header("Pragma: no-cache");
header("Expires: 0");
print $csv_output;
exit;
}

Check your bindValue calls: You give 1 parameter (a long string). It needs at least two. Check all the '
for example, it should be:
$_stmt->bindValue(':'.$field, $val, PDO::PARAM_INT);
i want to update all row's alternativegroups with $id value.
the action getting error: coldchain can not be null.
when i search the db for pk = $a, It's coldchain value is boolen(false). and db is postgresql
how can i set $q->attributes without posting other values?
public function actionUpdate($id){
if (isset($_POST['forms'])){
$arr = explode(',', $_POST['forms']);
foreach ($arr as $a){
$q = MedicineDrugform::model()->findbypk($a);
$q->alternativegroup = $id;
if ($q->save()){
echo $q->id."q saved <br />";

echo $quu->id."qu saved <br />";
}
}

$this->render('/site/messages', array('message'=>'formsaved'));

maybe it cant find the corresponding record for

Is it possible, when saving a Zend_Db_Table_Row, to make ZF apply a SQL function on one column?
For example, if $row->save() generates by default this SQL query:
UPDATE table SET field = ? WHERE id = ?;
I would like it to automatically apply the GeomFromText() function on this field:
UPDATE table SET field = GeomFromText(?) WHERE id = ?;
Thanks for any hint on how to do this with Zend_Db!
Define a custom update method in your class that inherits from Zend_Db_Table (not from the Zend_Db_Table_Row) and use a Zend_Db_Expr to set the column to the function return value.
See the docs here: http://framework.zend.com/manual/en/zend.db.table.html#zend.db.table.extending.insert-update.
I am just guessing but you could try this:
<?php
class MyTable extends Zend_Db_Table_Abstract
{
protected $_name = 'my_table';
public function update(array $data, $where) {
/**
* Build "col = ?" pairs for the statement,
* except for Zend_Db_Expr which is treated literally.
*/
$set = array();
$i = 0;
foreach ($data as $col => $val) {
if ($val instanceof Zend_Db_Expr) {
$val = $val->__toString();
unset($data[$col]);
} else {
if ($this->_db->supportsParameters('positional')) {
$val = ($col == 'field') ? 'GeomFromText(?)' : '?';
} else {
if ($this->_db->supportsParameters('named')) {
unset($data[$col]);
$data[':col'.$i] = $val;
$val = ($col == 'field') ? 'GeomFromText(:col'.$i.')' : ':col'.$i;
$i++;
} else {
/** #see Zend_Db_Adapter_Exception */
require_once 'Zend/Db/Adapter/Exception.php';
throw new Zend_Db_Adapter_Exception(get_class($this) ." doesn't support positional or named binding");
}
}
}
$set[] = $this->_db->quoteIdentifier($col, true) . ' = ' . $val;
}
$where = $this->_whereExpr($where);
/**
* Build the UPDATE statement
*/
$sql = "UPDATE "
. $this->_db->quoteIdentifier($this->_name , true)
. ' SET ' . implode(', ', $set)
. (($where) ? " WHERE $where" : '');
/**
* Execute the statement and return the number of affected rows
*/
if ($this->_db->supportsParameters('positional')) {
$stmt = $this->_db->query($sql, array_values($data));
} else {
$stmt = $this->_db->query($sql, $data);
}
$result = $stmt->rowCount();
return $result;

i have a protected directory where only user on .htpasswd can access, but sometimes it requires the user to change password or username, edit a specific username password to his username him self
sample users
kevien : kka

And same thing goes to password

$oldpass > Option: Add more security, user must known old password to change it.

Demo of crypt_apr1_md5() is available here.
Note that as of Apache 2.4, bcrypt is supported, so you can (and SHOULD) just use password_hash() on newer versions of Apache for this purpose.
Ofc this is just a sample, that will read your current file, find the given username and change either it is password of username.
Please keep in mind that this code is not safe and you would still need to parse the username and password so it does not break your file.
$username = $_POST['user'];
$password = $_POST['pass'];
$new_username = $_POST['newuser'];
$new_password = $_POST['newpass'];
$action = $_POST['action'];
//read the file into an array
$lines = explode("\n", file_get_contents('.htpasswd'));
//read the array and change the data if found
$new_file = "";
foreach($lines as $line)
{
$line = preg_replace('/\s+/','',$line); // remove spaces
if ($line) {
list($user, $pass) = split(":", $line, 2);
if ($user == $username) {
if ($action == "password") {
$new_file .= $user.':'.$new_password."\n";
} else {
$new_file .= $new_username.':'.$pass."\n";
}
} else {
$new_file .= $user.':'.$pass."\n";
}
}
}
//save the information
$f=fopen(".htpasswd","w") or die("couldn't open the file");
fwrite($f,$new_file);
fclose($f);
Don't. Store your authdb in a database instead, via e.g. mod_auth_mysql.
Googled "php generate htpasswd", got this article: How to create a password for a .htpasswd file using PHP.
The key line seems to be:
$password = crypt($clearTextPassword, base64_encode($clearTextPassword));
So I imagine you'd read in the file contents with file_get_contents, parse it into an associative array, modify the relevant entries (encrypting the password as shown above), write the array back into a string, and use file_put_contents to write the file back out.
This is most definitely not standard practice, however. Sounds like the job for a database. If you feel weird about setting up a whole database server, and your host supports it, SQLite might be a good choice.
Just in case someone is just looking for a working script, here is a solution.
It is the script published here by Kavoir with a minor change: http://www.kavoir.com/backyard/showthread.php?28-Use-PHP-to-generate-edit-and-update-htpasswd-and-htgroup-authentication-files
<?php
/*
$pairs = array(
'username' = 'password',
);
*/
// Algorithm: SHA1
class Htpasswd {
private $file = '';
public function __construct($file) {
if (file_exists($file)) {
$this -> file = $file;
} else {
return false;
}
}
private function write($pairs = array()) {
$str = '';
foreach ($pairs as $username => $password) {
$str .= "$username:{SHA}$password\n";
}
file_put_contents($this -> file, $str);
}
private function read() {
$pairs = array();
$fh = fopen($this -> file, 'r');
while (!feof($fh)) {
$pair_str = str_replace("\n", '', fgets($fh));
$pair_array = explode(':{SHA}', $pair_str);
if (count($pair_array) == 2) {
$pairs[$pair_array[0]] = $pair_array[1];
}
}
return $pairs;
}
public function addUser($username = '', $clear_password = '') {
if (!empty($username) && !empty($clear_password)) {
$all = $this -> read();
// if (!array_key_exists($username, $all)) {
$all[$username] = $this -> getHash($clear_password);
$this -> write($all);
// }
} else {
return false;
}
}
public function deleteUser($username = '') {
$all = $this -> read();
if (array_key_exists($username, $all)) {
unset($all[$username]);
$this -> write($all);
} else {
return false;
}
}
public function doesUserExist($username = '') {
$all = $this -> read();
if (array_key_exists($username, $all)) {
return true;
} else {
return false;
}
}
private function getHash($clear_password = '') {
if (!empty($clear_password)) {
return base64_encode(sha1($clear_password, true));
} else {
return false;
}
}
}
You can use this script like:
$htp = new Htpasswd('.htpasswd');
$htp -> addUser('username1', 'clearpassword1'); // this will add or edit the user
$htp -> deleteUser('username1');
// check if a certain username exists
if ($htp -> doesUserExist('username1')) {
// user exists
}
