I have set of questions have you ever encounter some issues when multiple save on database?my problem is this, i have a database called "album" where fields are 'album_id,album_title,album_user'.
The html output would be there is a login section where there is a input type file where you want to add more and once you have uploaded it. and array of set of names will be stored and that array will be our que to save the file on the multiple format the problem is that. it says and error on the database whichs is sql specified twice.Do you have an idea on how to save in multiple using php?
code will be like this.
<?php
class Album extends olib{
function __construct(){
parent::olib();
}
function upload_submit() {
$allow = array("jpg","png","gif");
$directory = "upload";
$pictures = array();
$counter = 0;
$error = '';
if($this->jpost('upload')) {
for($getupload = 0;$getupload<count($_FILES['uploadpictures']['name']);$getupload++){
$extension = end(explode(".",$_FILES['uploadpictures']['name'][$getupload]));
if(in_array(strtolower($extension),$allow)){
if(move_uploaded_file($_FILES['uploadpictures']['tmp_name'][$getupload],$directory."/".$_FILES['uploadpictures']['name'][$getupload])){
$pictures[$getupload] = $_FILES['uploadpictures']['name'][$getupload];
$counter++;
// $this->save_user_album($_FILES['uploadpictures']['name'][$getupload],$this->setSession('user_id'));
}else{
$error[$getupload] = "Sorry seems some of the data invalid";
}
}else{
$error = '1';
}
}
print_r($pictures);
print_r($error);
foreach($pictures as $urpics){
$this->save_user_album($urpics,$this->setSession('user_id'));
}
}
}
function save_user_album($albumtitle,$session){
$_firewall = ($this->setSession('user_id') !=="") ? $this->setSession('user_id') : "";
$this->jfields('album_pics_title',$albumtitle);
// $this->jfields('album_pics_user',$session);
return $this->jSave('album_pics');
}
}
any response will greatly appreciated!!
Hi I'm sorry seems i have a solution for this i have unset after it has been save..
unset($this->jfields); problem has been solved

I've an application in PHP 4.3.9 and I've a problem with SESSION.
When I put a variable SESSION in an other variable, like this :
$tempInsInscription = $_SESSION['ins_inscription'];
$_SESSION['ins_inscription'] content is removed.
I don't understand why. Is a PHP4 particularity ?
EDIT
I tried many case to found where exactly I lose my content and this is in a foreach :
reset($tempInsInscription);
foreach($tempInsInscription as $key => $ins_inscription){
if(is_array($ins_inscription)){
reset($ins_inscription);
foreach($ins_inscription as $key_etape => $etape){
$_SESSION["dossier"][$key_etape]=$etape;
}
}else{
$_SESSION["dossier"][$key]=$ins_inscription;
}
}
SOLUTION
I found a solution to solve my problem. here my new code & it's works perfectly :
$tempInsInscription = $_SESSION['ins_inscription'];
$_SESSION['ins_inscription'] = $tempInsInscription;
reset($tempInsInscription);
while(list($key, $ins_inscription) = each($tempInsInscription)) {
if(is_array($ins_inscription)){
reset($ins_inscription);
while(list($key_etape, $value_etape) = each($ins_inscription)) {
$dossier[$key_etape]=$value_etape;
}
}else{
$dossier[$key]=$ins_inscription;
}
}

i have a script that keeps reloading every 2 seconds, i made a code to create a txt file for each user IP and write the user name $name inside it. my problem is that everytime my script reloads it will write the $name of the specific IP again with every reload.
the code is
$ip_file = "ips/".$ip.".txt";
$logip = fopen($ip_file,"a", 1);
$name = $name."\n";
fwrite($logip, $name);
fclose($logip);
return;
i need some way to verify if the name is already in the $ip_file and if it's there then not to write it again.
the idea behind this is to check if the same IP is used by more than one $name and then create a function to check all the $ip_file files for more than 1 $name and if so ban the violating $ip
thanks in advance
$ip_file = "ips/".$ip.".txt";
$names = file_get_contents($ip_file); //read names into string
if(false === strpos($names,$name)) { //write name if it's not there already
file_put_contents($ip_file,"$name\n",FILE_APPEND);
}
Is this what you need?
<?php
$ip_file = "ips/".$ip.".txt";
$name = $name."\n";
if (file_exists($ip_file)) {
$valueInFile = file_get_contents($ip_file, true);
if ($valueInFile == $name) {
//Do something
}
} else {
$logip = fopen($ip_file,"a", 1);
fwrite($logip, $name);
fclose($logip);
}
return;
?>

I am a newbie and trying to implement a simple validation script after reading up, but I can't see how I can have multiple Ifs that will only do an sql insert if all required fields are met. Rather than having the multiple else statements, what is a syntax approach for having all the form validation Ifs together and if one of them fails, then the correct error is shown and the sql is not execute?
if(isset($_POST ['submit'])){
$user_ID = get_current_user_id();
$catErr = $ratingErr = $titleErr = $textErr = "";
if (empty($_POST["category"])) {
$catErr = "Category is required";
} else {
//DO THE INSERT BELOW!
}
if (empty($_POST["rating"])) {
$ratingErr = "Rating is required";
} else {
//DO THE INSERT BELOW!
}
if (empty($_POST["post_name"])) {
$postErr = "Title is required";
} else {
//DO THE INSERT BELOW!
}
if (empty($_POST["text"])) {
$textErr = "Text is required";
} else {
//DO THE INSERT BELOW!
}
//PDO query begins here...
$sql = "INSERT INTO forum(ID,
category,
rating,
post_name,
text
Use one variable for all the error messages and concatenate to it in the branches, so in the end if that variable is still empty string you won't do the insert. (And you don't need any of the empty else blocks that contain nothing but a comment.)
$err = "";
if (empty($_POST["category"])) {
$err .= "<br/>Category is required";
}
if (empty($_POST["rating"])) {
$err .= "<br/>Rating is required";
}
if (empty($_POST["post_name"])) {
$err .= "<br/>Title is required";
}
if (empty($_POST["text"])) {
$err .= "<br/>Text is required";
}
//PDO query begins here...
if($err=='')
{
$sql = "INSERT INTO forum(ID,
category,
rating,
...";
...
}
There are many solutions to your problem. Here are 3 methods of solving your issue.
You could combine all of your if statements like so:
if (empty($_POST['rating']) || empty($_POST'rating']) || ... ) { ... }
and separate them by double pipes.
You could also check the entire array:
if (empty($_POST)) $error = "There was an error!";
You could set a universal error variable and then output it.
A third solution could keep your current syntax but cut down on the amount of lines. You could save lines by doing without brackets. You can create an array and push your errors to the array.
Note: You can use empty() or isset().
// create an array to push errors to
$errors_array = array();
// if a particular field is empty then push the relevant error to the array
if(!isset($_POST['category'])) array_push($errors_array, "Category is required");
if(!isset($_POST['rating'])) array_push($errors_array, "Rating is required");
...
Once you have an array full of errors you can check for them like so:
// if the array is not empty (then there are errors! don't insert!)
if (count($errors_array) > 0) {
// loop through and echo out the errors to the page
for ($i = 0; $i < count($errors_array); $i++) {
echo $errors_array[i];
}
} else {
// success! run your query!
}
You should use javascript to validate the page before it is even processed into a post. This script will run client-side when they hit submit and catch errors before they even leave the page.
Here's a tutorial on how to do something like that: tutorial
Each field can have its own validation parameters and methods, and it will also make the page's code look a lot nicer.
I got it to go with this approach after showdev got me thinking that way. It's not very elegant perhaps, but does the trick, although all the user is taken to a blank page if there are errors and it simple says: Missing category (or whatever). Wondering if I can echo a link or something back to the page with the form from there so the user has an option like "go back and resubmit". Otherwise I will have to handle and display the errors alongside the form which will require a different approach altogether...
if(isset($_POST ['submit'])){
$errors = false;
if(empty($_POST['category'])) {
echo 'Missing category.<br>';
$errors = true;
}
if(empty($_POST['rating'])) {
echo 'Missing rating.<br>';
$errors = true;
}
if(empty($_POST['post_name'])) {
echo 'Missing title.<br>';
$errors = true;
}
if(empty($_POST['text'])) {
echo 'Missing text.<br>';
$errors = true;
}
if($errors) {
exit;
}
// THEN ADD CODE HERE. But how display form again if user makes errors and sees nothing but error message on page if they miss something (which is how it works now)
Generally, if you find yourself repeatedly writing very similar statements, using some sort of loop is probably a better way to go about it. I think what you said about "handling and displaying the errors alongside the form" is really what you need to do if you want the process to be user-friendly. If you put your validation script at the top of the file that has your form in it, then you can just have the form submit to itself (action=""). If the submission is successful, you can redirect the user elsewhere, and if not, they will see the form again, with error messages in useful places.
if (isset($_POST['submit'])) {
// define your required fields and create an array to hold errors
$required = array('category', 'rating', 'post_name', 'text');
$errors = array();
// loop over the required fields array and verify their non-emptiness
foreach ($required as $field) {
// Use empty rather than isset here. isset only checks that the
// variable exists and is not null, so blank entries can pass.
if (empty($_POST[$field])) {
$errors[$field] = "$field is required";
}
}
if (empty($errors)) {
// insert the record; redirect to a success page (or wherever)
}
}
// Display the form, showing errors from the $errors array next to the
// corresponding inputs
I am new in this json chapter.I have a file named mysql_conn.php .This file have a php function to call data from mysql database.So can anyone help me to create one json file to get data from mysql_conn.php.Below is my code
mysql_conn.php
function getWrkNoTest($wrkno){
$conf = new BBAgentConf();
$log = new KLogger($conf->get_BBLogPath().$conf->get_BBDateLogFormat(), $conf->get_BBLogPriority() );
$connection = MySQLConnection();
$getWrkNoTest ="";
$lArrayIndex = 0;
$query = mysql_query("
SELECT
a.jobinfoid,
a.WRKNo,
a.cate,
a.det,
a.compclosed,
a.feedback,
a.infoID,
b.callerid,
b.customername
FROM bb_jmsjobinfo a
LEFT JOIN bb_customer b
ON a.customerid = b.customerid
WHERE a.WRKNo = '$wrkno';"
);
$result = mysql_query($query);
$log->LogDebug("Query[".$query."]");
while ($row = mysql_fetch_array($result)){
$getWrkNoTest = array("jobinfoid"=>$row['jobinfoid'],
"WRKNo"=>$row['WRKNo'],
"cate"=>$row['cate'],
"det"=>$row['det'],
"compclosed"=>$row['compclosed'],
"feedback"=>$row['feedback'],
"infoID"=>$row['customerid'],
"customerid"=>$row['infoID'],
"callerid"=>$row['callerid'],
"customername"=>$row['customername']);
$iList[$lArrayIndex] = $getWrkNoTest;
$lArrayIndex = $lArrayIndex + 1;
}
$QueryResult = print_r($getWrkNoTest,true);
$log->LogDebug("QueryResult[".$QueryResult."]");
closeDB($connection);
return $iList;
}
json.php
if ($_GET['action']=="getJsonjms"){
$wrkno = $_GET["wrkno"];
if($wrkno != ""){
$jms = getWrkNoTest($wrkno);
if(!empty($jms)){
echo json_encode($jms);
}else{
echo "No data.";
}
}else{
echo "Please insert wrkno";
}
}
I dont know how to solve this.Maybe use foreach or something else.Sorry for my bad english or bad explanation.I'm really new in this json things. Any help will appreciate.Thanks
If I understand your question right, you want to convert the results you receive from your MySQL query into JSON and then store that data into a file?
If this is correct, you can build off of what you currently have in json.php. In this block here, you use json_encode():
if(!empty($jms)){
echo json_encode($jms);
}
We can take this data and pass it to file_put_contents() to put it into a file:
if (!empty($jms)) {
$json = json_encode($jms);
// write the file
file_put_contents('results.json', $json);
}
If this is a script/page that's visited frequently, you'll want to make the filename (above as results.json) into something more dynamic, maybe based on the $wrkno or some other schema.
well i'm writing a php code to edit tags and data inside those tags but i'm having big trouble getting my head around the thing.
basically i have an xml file similar to this but bigger
<users>
<user1>
<password></password>
</user1>
</users>
and the php code i'm using to try and change the user1 tag is this
function mod_user() {
// Get global Variables
global $access_level;
// Pull the data from the form
$entered_new_username = $_POST['mod_user_new_username'];
$entered_pass = $_POST['mod_user_new_password'];
$entered_confirm_pass = $_POST['mod_user_confirm_new_password'];
$entered_new_roll = $_POST['mod_user_new_roll'];
$entered_new_access_level = $_POST['mod_user_new_access_level'];
// Grab the old username from the last page as well so we know who we are looking for
$current_username = $_POST['mod_user_old_username'];
// !!-------- First thing is first. we need to run checks to make sure that this operation can be completed ----------------!!
// Check to see if the user exist. we just use the normal phaser since we are only reading and it's much easier to make loop through
$xml = simplexml_load_file('../users/users.xml');
// read the xml file find the user to be modified
foreach ($xml->children() as $xml_user_get)
{
$xml_user = ($xml_user_get->getName());
if ($xml_user == $entered_new_username){
// Set array to send data back
//$a = array ("error"=>103, "entered_user"=>$new_user, "entered_roll"=>$new_roll, "entered_access"=>$new_access_level);
// Add to session to be sent back to other page
// $_SESSION['add_error'] = $a;
die("Username Already exist - Pass");
// header('location: ../admin.php?page=usermanage&task=adduser');
}
}
// Check the passwords and make sure they match
if ($entered_pass == $entered_confirm_pass) {
// Encrypt the new password and unset the old password variables so they don't stay in memory un-encrytped
$new_password = hash('sha512', $entered_pass);
unset ($entered_pass, $entered_confirm_pass, $_POST['mod_user_new_password'], $_POST['mod_user_confirm_pass']);
}
else {
die("passwords did not match - Pass");
}
if ($entered_new_access_level != "") {
if ($entered_new_access_level < $access_level){
die("Access level is not sufficiant to grant access - Pass");
}
}
// Now to load up the xml file and commit changes.
$doc = new DOMDocument;
$doc->formatOutput = true;
$doc->perserveWhiteSpace = false;
$doc->load('../users/users.xml');
$old_user = $doc->getElementsByTagName('users')->item(0)->getElementsByTagName($current_username)->item(0);
// For initial debugging - to be deleted
if ($old_user == $current_username)
echo "old username found and matches";
// Check the variables to see if there is something to change in the data.
if ($entered_new_username != "") {
$xml_old_user = $doc->getElementsByTagName('users')->item(0)->getElementsByTagName($current_username)->item(0)->replaceChild($entered_new_username, $old_user);
echo "Username is now: " . $current_username;
}
if ($new_pass != "") {
$current_password = $doc->getElementsByTagName($current_user)->item(0)->getElementsByTagName('password')->item(0)->nodeValue;
//$replace_password = $doc
}
}
when run with just the username entered for change i get this error
Catchable fatal error: Argument 1 passed to DOMNode::replaceChild() must be an instance of DOMNode, string given, called in E:\xampp\htdocs\CGS-Intranet\admin\html\useraction.php on line 252 and defined in E:\xampp\htdocs\CGS-Intranet\admin\html\useraction.php on line 201
could someone explain to me how to do this or show me how they'd do it.. it might make a little sense to me to see how it's done :s
thanks
$entered_new_username is a string so you'll need to wrap it with a DOM object, via something like$doc->createElement()
$xml_old_user = $doc->getElementsByTagName('users')->item(0)->getElementsByTagName($current_username)->item(0)->replaceChild($doc->createElement($entered_new_username), $old_user);
This may not be quite right, but hopefully it points you in the correct direction.
alright got it writing and replacing the node that i want but i have ran into other issues i have to work out (IE: it's replacing the whole tree rather then just changing the node name)
anyway the code i used is
// For initial debugging - to be deleted
if ($old_user == $current_username)
echo "old username found and matches";
// Check the variables to see if there is something to change in the data.
if ($entered_new_username != "") {
try {
$new_node_name = $doc->createElement($entered_new_username);
$old_user->parentNode->replaceChild($new_node_name, $old_user);
}
catch (DOMException $e) {
echo $e;
}
echo "Username is now: " . $current_username;
}
if ($new_pass != "") {
$current_password = $doc->getElementsByTagName($current_user)->item(0)->getElementsByTagName('password')->item(0)->nodeValue;
//$replace_password = $doc
}
$doc->save('../users/users.xml');
