With this code, it can retrieve the values from the database with a checkbox on each row. What I want for it to do is to update the unchecked values (namely 0) in the database with 1 for each checkbox checked.
Here's the query for the database and some sample rows.
CREATE TABLE IF NOT EXISTS `job_order` (
`ID` int(255) NOT NULL AUTO_INCREMENT,
`SI_no` varchar(12) NOT NULL DEFAULT '1',
`Date_Issued` date NOT NULL,
`Date_completed` date DEFAULT NULL,
`checked` int(1) NOT NULL DEFAULT '0',
PRIMARY KEY (`ID`)
) ENGINE=MyISAM AUTO_INCREMENT=5 DEFAULT CHARSET=latin1;
INSERT INTO `job_order` (`ID`, `SI_no`, `Date_Issued`, `Date_completed`,
`checked`) VALUES
(1, '2', '2018-12-19', '2018-12-26', 1),
(2, '5', '2018-11-06', '2018-12-04', 1),
(3, '7', '2018-12-01', '2018-12-13', 0),
(4, '8', '2018-12-20', '2018-12-12', 0);

I'm mostly having problems with the function complete_orders, which doesn't return anything on button press of the submit button. Nor does it check if the checkboxes are ticked.
Here's the HTML layout file
jobrequestfilter.php

$dbc = new db_c();
$msg = '';
if(isset($_POST) && isset($_POST['process_orders'])){

if(is_array($process) && !empty($process)){
$msg = '<tr><td colspan="3">Successfully Processed '.count($process).' Orders</td></tr>';
}
else{
echo '<script>console.log("Nothing processed at jobrequestfilter")</script>';
}

$data = $dbc->orders_2_table();

The isset button returns the echo statement I put, however, most seems to be working fine except for the process order button. Is it wise to just use javascript for the checkbox on update?
Try this one
db_c.php
It should not be
$order['order-complete']
But
$orders
Because the array variable name from post already stored in variable $orders.
It should not be
$id
But
$ids
Because you declare it as
foreach($orders as $ids)
<?php
define ( 'DB_HOST', 'localhost' );
define ( 'DB_USER', 'root' );
define ( 'DB_PASS', '' );
define ( 'DB_NAME', 'your_db_name' );

Please replace below complete_orders function code
function complete_orders($orders){
$processed = array();
if(is_array($orders) && !empty($orders)){
if(isset($orders['order-complete'])){
foreach($orders['order-complete'] as $id){
$sql = "UPDATE `job_order` SET `checked`= 1 WHERE `ID` = ?";
if($stmt = $this->mysqli->prepare($sql)){
$stmt->bind_param("i", $id);
if($stmt->execute()){
array_push($processed, $id);
}
}
}
return $processed;
}else{
echo '<script>console.log("Nothing returned line 32")</script>';
return 0; //No orders selected
}
}else{
echo '<script>console.log("Nothing processed")</script>';
return 0; //Nothing to process
}
}
Two problem in code:
Function argument $orders you are passing but while process you using order. So it's was not going inside into loop
in foreach iteration your are using ids but while updating query you using id. so change variable accordingly. Please check

I am looking for answers on Stack Overflow and Google, have read about 50 same questions, every time its different, my head is already boiling. I have a simple PHP CRUD application with OOP.
It has a connection to the database (it works, my data is fetched from the database and I could see it at my index.php in Opera/Safari), has 'add' action (it doesn't work - white page), 'edit' action (it doesn't work - white page), 'delete' action (it works).
UPDATE2:
I have changed cli interpreter to 5.6. Now I see some errors (if I add this line to .ini file 'always_populate_raw_post_data' to '-1' errors are disappear, but I see a white page again):
Deprecated: Automatically populating $HTTP_RAW_POST_DATA is .
deprecated and will be removed in a future version. To avoid this
warning set 'always_populate_raw_post_data' to '-1' in php.ini and
use the php://input stream instead. in Unknown on line 0

Seems you want to put an array variable data directly into table which is supposed to throw error,
Here is the solution.
For adding all value of an array directly into table you have to use first convert array into json and then need to insert it into database. like this..
$resultJson = json_encode($result);
$query = mysql_query("Insert into tbl_attendence (StudentRollNumber,SubjectId,Attendence,Date)VALUES(".$stud.", ".$resultJson.", ".$present.", ".$date.")");
AND if you want to add all array value into database for each value per row separately then you have to make sure run the loop and then insert each value into database for each record.
If I understand you right you want to upload something like this:
Array([1] => '1', [2] => '2')
into a table, which would not work. So you'd have to use JSON to stringify the array. Example:
<?php
$value = 'Some string';
$value2 = 'Some other string';
$values = Array('String 1', 'String 2', 'String 3');
$json_values = json_encode($values);
$mysqli = new mysqli('HOSTNAME', 'USERNAME', 'PASSWORD', 'DATABASE'); // Connecting to SQL Server
// Checking if connection was successfull
if( $mysqli->connect_errno ){
echo 'There was an error connection to the SQL Server<br>';
echo '(' . $mysqli->connect_errno . ') ' . $mysqli->connect_error;
exit; // FAIL
}
// Preparing a statement
$stmt = $mysqli->prepare('INSERT into TABLENAME(value, value2, values) VALUES(?, ?, ?)');
// Checking if php prepared the statement successfully
if(!$stmt){
echo 'There was an error preparing the statement!';
exit;
}
if( !$stmt->bind_param('sss', $value, $value2, $json_values) ){
echo 'There was an error binding params to the statement!';
exit;
}
$stmt->execute();
?>
to post arrays into DB I use this approach:
//database connection class
class Database{
// specify your own database credentials
private $host = "YOUR HOST";
private $db_name = "DATABASE NAME";
private $username = "USERNAME";
private $password = "PASSWORD";
public $conn;
// get the database connection
public function getConnection(){ $this->conn = null;
try{
$this->conn = new PDO("mysql:host=" . $this->host . ";dbname=" . $this->db_name, $this->username, $this->password);
}catch(PDOException $exception){
echo "Connection error: " . $exception->getMessage();
}
return $this->conn;
}
}
//model class
class Model{
// database connection
private $conn;
// constructor with $db as database connection
public function __construct($db){
$this->conn = $db;
}
// add info to db
function create($fieldset){
$this->conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// query to insert record
$query = "INSERT INTO
tbl_attendence
SET
$fieldset";
// prepare query
$stmt = $this->conn->prepare($query);
// execute query
if($stmt->execute()){
return true;
}else{
return false;
}
}
}
//part that will handle the post
// get database connection
$database = new Database();
$db = $database->getConnection();
//instatiate model
$model = new Model($db);
//function that will filter posted values
function filter($value){
$value = trim($value);
$value = strip_tags($value);
$value = stripslashes($value);
$value = htmlentities($value);
return $value;
}
if(!empty($_POST)){
//Get Variables
foreach($_POST as $key => $value){
//this part will tackle values which are arrays
if(is_array($value)){
$val=implode(",",filter($value));
$groupVal[] = $val;
$groupKeys[] = $key;
}
else{
$groupVal[] = $this->filter($value);
$groupKeys[] = $key;
}
}
//count items in array to establish a limit
$limit = count($_POST);
//arranges the data into "key = value" format
for($i=0;$i<$limit;$i++){
$prepFieldset[$i] = "$groupKeys[$i] = $groupVal[$i]";
}
//prepares the fieldset to be used in SQL query
$fieldset = implode(",",$prepFieldset);
//process them in the model
$status = $model->create($fieldset);
//show response
if($status == true){
$response = 'Data saved';
}
else{
$response = 'Error when saving data';
}
}

SO where is the problem..the image is not being inserted.
this is the html
<form action="slider.php" method="post" enctype="multipart/form-data">
<div class="form-group">
<label>Slider Image input</label>
<input type="file" name="sliderimage"> </input>
</div>
<button type="submit" name="btnSubmit" class="btn btnsuccess">Submit</button>
<button type="reset" class="btn btn-danger">Reset </button>
</form>
There was a typo or rather variable misplacement in your code. Where you were supposed to do $slider->image=... You did $slider->sliderimage=... of which public $image and not public $sliderimage was declared on your Slider Class. See the Corrected version of your code below:ยจ
<?php
if(isset($_POST['btnSubmit'])){
$errror = array();
$slider = new Slider;
if(!empty($_FILES['sliderimage']['name'])){
// YOU PROBLEM IS RIGHT HERE... NOT $slider->sliderimage
// RATHER $slider->image AS IT IS IN YOUR SLIDER CLASS
$slider->image = $_FILES['sliderimage']['name'];
move_uploaded_file($_FILES['sliderimage']['tmp_name'], 'images/' . $_FILES['sliderimage']['name']);
}else{
$error['image']= "Image required";
}
I hope you are doing great. I'm having a problem where I cannot insert data into my database. There are multiple reasons to why that happens so don't consider it a duplicate question please. I checked my code. For one table it saves the data but for this table. It displays that the same page was not found and no data is saved on the local database. I hope you can help me guys. Thanks in advance. :)
Here are some useful pieces of code:
<?php
include 'Header.php';
?>
<style>
#first {
//margin-right: 100%;
//clear: both;
}
#first > img {
display: inline-block;
//float: left;
}
#first > p {
//float: left;
display: inline-block;
//margin-left: 60px;
//margin-bottom: 120px;
}
</style>

Output show when I click insert button:
Not Found
The requested URL /IndividualProject/Comment.php was not found on this server.
Apache/2.4.17 (Win64) PHP/5.6.16 Server at localhost Port 80
I encountered this kind of issue when working on a staging site because webhosting may have different kinds of restrictions and strict. Now what I did is changing the filename for example:
Class name should match the filename coz it's case sensitive.
Comment.php
class Comment extends DBConn {
function __construct () {
parent::__construct ();
}
//code here..
}
I can upload images as a serialized array no problem, but all I need is to store the raw filename string on my database and I'm not sure where to start editing my pre-existing code get this to work. This should be easier but as a PHP novice I can't get it to work.
Essentially, I want to be able to upload images then display them on the front end of my site doing something like this:
<img src="img/<php echo $config->photo_a ?>"/>
My existing code is:
<?php
//connect to db //
session_start();
include('../config.php');
// check for login to use //
if (!$user->authenticated)
{
header('Location: login.php');
die();
}
//post form as array using class photo_loader//
if (isset($post->form_action))
{
$a = new photo_loader(false, $db);
$a->name = $post->name;
$image_files = array();
for ($i=1; $i<10; $i++)
{
if (isset($_FILES['file'.$i]['name']) && $_FILES['file'.$i]['name'] != "")
{
$img = new upload($_FILES['file'.$i], M_ENV_SITE_URL, M_ENV_SITE_ROOT);
$img->set_upload_target("/img/");
$n = $img->do_upload();
if (!$n)
{
$err = "Image file ".$i." too big or wrong file type.";
}
else
{
$image_files[] = $n;
$img->batchResize("/img/", "/img/", $n, array("320x240", "800x600"));
}
}
}
if (empty($image_files)) $err = "You must include at least one image.";
$a->value = $image_files;
if (!$err)
{
$a->create();
$succ = "Success!";
}
}
?>
Using a simple form like this:
<form action="" method="post" enctype="multipart/form-data">
<div class="control-group"><label for="file" class="control-label">Attach Slideshow Images:</label><div class="controls">
<?php
for ($i=1;$i<10;$i++)
{
echo "<input name=\"file".$i."\" type=\"file\" value=\"\" id=\"file".$i."\" />";
} ?>
</div></div>
<input type="hidden" name="name" value="photo_a">
<div class="form-actions">
<input type="submit" name="form_action" class="btn btn-large btn-primary" value="Save" />
</div>
</form>
and photo_loader.class.php looks like this:
<?php
class photo_loader
{
private $properties;
var $db;
function __construct($id, $dbase)
{
$this->db = $dbase;
if (is_numeric($id))
{
$sql = sprintf(
"SELECT * FROM minty_config
WHERE ID=%d",
$this->db->clean($id)
);
$result = $this->db->query($sql);
$fields = $this->db->fetch_array($result);
foreach ($fields as $k => $v)
{
$this->properties[$k] = $v;
}
$this->value = unserialize($this->value);
}
}
function __get($k)
{
return $this->properties[$k];
}
function __set($k, $v)
{
$this->properties[$k] = $v;
}
function update()
{
$sql = sprintf(
"UPDATE minty_config SET
name='%s',
value='%s'
WHERE ID=%d",
$this->db->clean($this->name),
serialize($this->value),
$this->ID
);
$this->db->query($sql);
}
function create()
{
$sql = sprintf(
"INSERT INTO minty_config
(name, value)
VALUES('%s', '%s')",
$this->db->clean($this->name),
unserialize($this->value)
);
$this->db->query($sql);
}
function delete()
{
$sql = sprintf(
"DELETE FROM minty_config
WHERE ID=%d",
$this->ID
);
$this->db->query($sql);
}
}
?>
I presume I need to remove the $image_files = array(); section but I don't know what to replace with! Seemingly keep making mistakes and returning blank pages with errors or not uploading the image. I can't see it being too diffuclt but I presume I'm going the wrong way about it. Many thanks in advance!!
