im trying to insert multiple JSON files into a database(about 20-30 in total, im using 2 for now to test). All the files will have the same format. I inserted the files into an HTML table previously so i used the same loop so my script inserts any JSON file found in the directory into the database. I am however getting some errors 1) "Undefined index : Comments" and 2) Table 'serverd.serverd' doesn't exist. Any guidance would be appreciated. I have moved my brackets around but no luck.
'<?php
$connect =mysqli_connect("reservation","-----","-----","serverD") or
die("could not connect");
$dir = "/Users/-----/Desktop/reserve/sql";
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
foreach(glob("*.json") as $filename) {
$jsondata = file_get_contents($filename);
$data = json_decode($jsondata, true);
$Manufacturer = $data['Comments']['Manufacturer'];
$Model = $data['Comments']['Model'];
$BIOSFamily = $data['Comments']['BIOSFamily'];
$BIOSDATE = $data['Comments']['BIOSDate'];
$SerialNumber = $data['Comments']['SerialNumber'];
$sql= " INSERT INTO serverD(Manufacturer, Model, BIOSFamily, BIOSDate, SerialNumber)
VALUES('$Manufacturer' , '$Model' , '$BIOSFamily' , '$BIOSDate' , '$SerialNumber')";
$query=mysqli_query($connect, $sql) or die (mysqli_error($connect));
}
}
}
?>'

I need to add query logging in Symfony and in csv file. Sometime database can be busy or not available but I want to log all queries.
This log should be in csv format with columns:
-url
-datasource name
-SQL content
-parameters
-username
-start time of query execution (accuracy in ms)
-end time of query execution (accuracy in ms)
Is any help how can I do this? or what can be done for this?
Maybe Custom Function In which I can create the csv file with the current login user info with the url and time to execute the query to access that particular url?
In Symfony If you have a common SQL function which runs when each
query executes then this one helpful for you.
This is the thing I have implemented in my case. Hope This may help you.
public function execute($parameters = null)
{
if ($this->executed) {
return $this;
}
$executionStartTime = microtime(true);
$stmt = $this->execute($parameters);
$this->result = $stmt->fetchAll();
// Close cursor to allow query caching.
$stmt->closeCursor();
$this->executed = true;;
$executionEndTime = microtime(true);
//below code is added to logging for SQL queries to web server in csv format
$execution_time = $executionEndTime - $executionStartTime;
$getpageParameter = $parameters;
$getusername = $this->getUser()->getUsername();
$url = $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
$parms = json_encode($getpageParameter);
$data = array(
date ("Y-m-d H:i:s")."|".$url."|".$getusername."|".$parms."|".$executionStartTime."|".$executionEndTime,
);
if(!file_exists('/../../app/logs/querylog.csv')){
$column = array(
"DATE & TIME|URL|USERNAME|PARAMETERS|START TIME|END TIME"
);
$fp = fopen('/../../app/logs/querylog.csv', 'a+');
foreach ( $column as $line ) {
$val = explode("|", $line);
fputcsv($fp, $val);
}
fclose($fp);
}
$fp = fopen('/../../app/logs/querylog.csv', 'a+');
foreach ( $data as $line ) {
$val = explode("|", $line);
fputcsv($fp, $val);
}
fclose($fp);
return $this;
}
The Code i tried is
$source = fopen('filename.csv', 'r') or die("Problem open file");
while (($data = fgetcsv($source, 1000, ",")) !== FALSE)
{
$name = $data[0];
`$mobile = $data[1];
mysql_query("INSERT INTO `table` (`name`,`mobile`) VALUES ('".$name."','".$mobile ."') ");
}
fclose($source);
but it takes only last record...
Why not just add the whole file using MySQL rather than breaking it up by line? Something like
LOAD DATA INFILE 'filename.csv' INTO TABLE table FIELDS TERMINATED BY ',';
or if you've got specific columns that need to go into specific fields,
LOAD DATA INFILE 'filename.csv' INTO TABLE table FIELDS TERMINATED BY ',' (#c1, #c2)
set name = #c1, mobile = #c2;
Here is an easy way to do it, using PHP fgetcsv() and mysqli():
1. Connect to mysqli:
$mysqli = new mysqli("localhost", "my_user", "my_password", "my_db");
2. Open your CSV file:
$source = fopen('filename.csv', 'r') or die("Problem open file");
3. With a loop read the CSV and put your inserts queries in a variable:
$query="";
do {
if ($fields[0]) {
$query.="INSERT INTO `table_name` (`name`, `mobile`) VALUES
(
'".addslashes($fields[0])."',
'".addslashes($fields[1])."'
)
;";
}
} while ($fields = fgetcsv($source,1000,",","'"));
4. Excute your query and close mysqli:
if($mysqli->multi_query($query)) echo "Data successfuly added";
$mysqli->close();

I would like to ask some help in inserting data from texfile to a database table....i created a php code to execute in inserting the files to the table but i have no luck in importing it...can anyone know to do this?help me please.
current php code:
<?php
$host= "localhost";
$user= "root";
$pass= "";
$db="klayton";
$connect= mysql_connect($host,$user,$pass);
if (!$connect)die ("Cannot connect!");
mysql_select_db($db, $connect);
$file = fopen("tblApplicants.txt","r");
while( $applicants = fgets($file) )
{
$sql = "INSERT INTO tb_applicants( aic,name ) VALUES ('$applicants')";
mysql_query($sql);
}
?>
Read each line from this file,skip every second line $i%2 == 0 do break;
explode it at " | " and get second ( $row[1] ) and nextone ( $row[2] ), then trim it, and make sql insert.
Try to do at this way
Recently I was making an upload component for joomla 3.1 back-end.
based on How to Save Uploaded File's Name on Database
I was successful in moving the file to the hard-drive,
however I just cant get the update query to work based on the posted post above.
I don't get any SQL errors and saving works, but somehow ignores the database part.
I really hope I missed something obvious. (btw I don't know the joomla way of queries very well)
In phpmyadmin the following query works:
UPDATE hmdq7_mysites_projects
SET project_file = 'test'
WHERE id IN (3);
I have tried the following queries:
$id = JRequest::getVar('id');
$db =& JFactory::getDBO();
$sql = "UPDATE hmdq7_mysites_projects
SET project_file =' " . $filename. "'
WHERE id IN (".$id.");";
$db->setQuery($sql);
$db->query();
$colum = "project_file";
$id = JRequest::getVar('id');
$data = JRequest::getVar( 'jform', null, 'post', 'array' );
$data['project_file'] = strtolower( $file['name']['project_file'] );
$db =& JFactory::getDBO();
$query = $db->getQuery(true);
$query->update('#__mysites_projects');
$query->set($column.' = '.$db->quote($data));
$query->where('id'.'='.$db->quote($id));
$db->setQuery($query);
$db->query();
Here is the current code:
class MysitesControllerProject extends JControllerForm
{
function __construct() {
$this->view_list = 'projects';
parent::__construct();
}
function save(){
// ---------------------------- Uploading the file ---------------------
// Neccesary libraries and variables
jimport( 'joomla.filesystem.folder' );
jimport('joomla.filesystem.file');
$path= JPATH_SITE . DS . "images";
// Create the gonewsleter folder if not exists in images folder
if ( !JFolder::exists(JPATH_SITE . "/images" ) ) {
JFactory::getApplication()->enqueueMessage( $path , 'blue');
}
// Get the file data array from the request.
$file = JRequest::getVar( 'jform', null, 'files', 'array' );
// Make the file name safe.
$filename = JFile::makeSafe($file['name']['project_file']);
// Move the uploaded file into a permanent location.
if ( $filename != '' ) {
// Make sure that the full file path is safe.
$filepath = JPath::clean( JPATH_SITE . "/images/" . $filename );
// Move the uploaded file.
JFile::upload( $file['tmp_name']['project_file'], $filepath );
$colum = "project_file";
$id = JRequest::getVar('id');
$data = JRequest::getVar( 'jform', null, 'post', 'array' );
$data['project_file'] = strtolower( $file['name']['project_file'] );
$db =& JFactory::getDBO();
$query = $db->getQuery(true);
$query->update('#__mysites_projects');
$query->set($column.' = '.$db->quote($data));
$query->where('id'.'='.$db->quote($id));
$db->setQuery($query);
$db->query();
}
// ---------------------------- File Upload Ends ------------------------
JRequest::setVar('jform', $data );
return parent::save();
}

The OP wrote:
Solved: after reviewing the post update record in database using jdatabase I made up some fixed test values. It turns out the query is correct but $data variable in the query had no data. $data['project_file'] = strtolower( $file['name']['project_file'] ); removed the array from first part and variable worked.
I am trying to export my MySQL tables from my database to a JSON file, so I can list them in an array.
I can create files with this code no problem:
$sql=mysql_query("select * from food_breakfast");
while($row=mysql_fetch_assoc($sql))
{
$ID=$row['ID'];
$Consumption=$row['Consumption'];
$Subline=$row['Subline'];
$Price=$row['Price'];
$visible=$row['visible'];
$posts[] = array('ID'=> $ID, 'Consumption'=> $Consumption, 'Subline'=> $Subline, 'Price'=> $Price, 'visible'=> $visible);
}
$response['posts'] = $posts;
$fp = fopen('results.json', 'w');
fwrite($fp, json_encode($response));
fclose($fp);
Now this reads a table and draws it's info from the fields inside it.
I would like to know if it is possible to make a JSON file with the names of the tables, so one level higher in the hierarchy.
I have part of the code:
$showtablequery = "
SHOW TABLES
FROM
[database]
LIKE
'%food_%'
";
$sql=mysql_query($showtablequery);
while($row=mysql_fetch_array($sql))
{
$tablename = $row[0];
$posts[] = array('tablename'=> $tablename);
}
$response['posts'] = $posts;
But now i am stuck in the last line where is says: $ID=$row['ID']; This relates to the info inside the Table and I do not know what to put here.
Also as you can see, I need to filter the Tables to only list the tables starting with food_ and drinks_
Any help is greatly appreciated:-)
There is no 'table id' in MySQL and therefore the result set from SHOW TABLES has no index id. The only index in the resultset is named 'Tables_in_DATABASENAME'.
Also you should use the mysqli library as the good old mysql library is depreacted. Having prepared an example:
<?php
$mysqli = new mysqli(
'yourserver',
'yourusername',
'yourpassword',
'yourdatabasename'
);
if ($mysqli->connect_errno) {
echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") "
. $mysqli->connect_error;
}
$result = $mysqli->query('SHOW TABLES FROM `yourdatabasename` LIKE \'%food_%\'');
if(!$result) {
die('Database error: ' . $mysqli->error);
}
$posts = array();
// use fetch_array instead of fetch_assoc as the column
while($row = $result->fetch_array()) {
$tablename = $row[0];
$posts []= array (
'tablename' => $tablename
);
}
var_dump($posts);
