Is it possible to create a multiple verification about one variable? Like this:
<?php
$name = null;
if(isset($name)){
$name = null;
//Ah the name is again null, let's retry
if(isset($name)){
$name = "Arthur";
//Great! The name is arthur !
}
}
?>
Not sure the application you will give to the script, but this should do. Remember PHP will run the script first, then return the page. You cannot have an infinite loop running like JavaScript.
<?php
$name = null;
while (false === isset($name)) {
// Your code in here
}

I have two forms that sends data using ajax. Both forms have their own scripts and I thought that I would be able to access the same $_POST[] variables on the separate scripts, but this is not working. I tried using session_start() and include_once and for some reason I can't figure out why the variables are not passing from script to script. I've been at it for three days researching for a solution so if you know what I'm doing wrong or have an alternative please let me know thanks.
javascript.
$('.test-input').load("test.php", {
'sendTo':sendTo,
'carrier':carrier,
'testSubmit':testSubmit
})
$('#error-display').load("textsms.php", {
'date':scheduleDate,
'firstname':firstName,
'number':number,
'message':message,
'time':time,
'service':service,
'submit':submit
})
test.php
if (isset($_POST['testSubmit'])) {
$sendTo = $_POST['sendTo'];
$carrier = $_POST['carrier'];
$sendToInvalid = false;
$testEmpty = false;
$sendTo = "";
if (!preg_match('/^\(?\b\d{3}[-.)\s]?\s?\d{3}[-.)\s]?\d{4}\b$/', $sendTo) and $sendTo !== '') {
$sendToInvalid = true;
} elseif (empty($sendTo) || empty($carrier)) {
$testEmpty = true;
} else {
$sendTo = preg_replace('/[-.()\s]/','',$sendTo).$carrier;
$_SESSION['sendTo'] = $sendTo;
}
}
Trying to get $sendTo to pass to textsms.php down below.
else {
include 'test.php';
$sendTo = $_SESSION['sendTo'];
$number = preg_replace('/[-.()\s]/','',$number);
$number = "(".substr($number,0,3).") ".substr($number,3,3)."-".substr($number,6,4);
if ($sendTo !== "contactme#aboutryansam.com") {
$header = $name."\r\n#: ".$number;
$sendMsg = $userMsg."\r\nOn: ".$date.$time."\r\nService: ".$service;
//mail($sendTo, "You win!", $sendMsg, $header);
echo $sendTo;
echo "it worked";
}
Of course, on the page you initialize the ajax, include the "header.php" file that has inside session_start(). include_once('header.php') in the test.php as well. It should do the trick.
It's not a good practice nowadays, I better suggest you to use cookies and access them with $_COOKIE. Even better, use a library that takes care of cookies like this one. JQuery also has very good cookie management.
I'm currently putting together a small web-based GUI to generate kickstart-scripts. I got a confirmation page that's sending the relevant data via POST to the PHP-page where the actual shell script is called to build the iso. So far it's working, but the page seems to execute the script before it outputs anything else (for example, the 'echo' I put in at the beginning of the page ...), and I'm absolutely clueless why. Would anyone care to enlighten me?
Here's the code to the PHP-page that's executing the shell script ...
echo 'Generating your ISO; this might take a while...';
sleep(20);
if (!isset($_POST['auth'])) {
$ad = 'N';
}
else {
$ad = 'Y';
}
if (!isset($_POST['oracle'])) {
$oracle = 'N';
}
else {
$oracle = 'Y';
}
if ((!isset($_POST['ip'])) or (!isset($_POST['hostname'])) or (!isset($_POST['rhsel'])) or (!isset($_POST['submit'])) or (!isset($_POST['gw'])) or (!isset($_POST['nm']))) {
die('Please use the correct form !');
}
if (isset($_POST['ip'])) {
$ip = trim($_POST['ip']);
}
if (isset($_POST['gw'])) {
$gw = trim($_POST['gw']);
}
if (isset($_POST['nm'])) {
$nm = trim($_POST['nm']);
}
if (isset($_POST['hostname'])) {
$hostname = trim($_POST['hostname']);
}
if (isset($_POST['rhsel'])) {
$rhsel = $_POST['rhsel'];
}
passthru("/usr/bin/sudo /data/skripte/webconfig.sh $rhsel $oracle $ad $ip $gw $nm $hostname 2>&1");
PHP scripts accessed via a browser are request-response, meaning all processing is done on the server prior to headers and content being sent to the client. This means you will not get a continually updating output like you would see on the command line. There is no way around this. Sorry.
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 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 have this code:
<?php
foreach($items as $item) {
$site = $item['link'];
$id = $item['id'];
$newdata = $item['data_a'];
$newdata2 = $item['data_b'];
$ch = curl_init($site.'updateme.php?id='.$id.'&data1='.$newdata.'&data2='.$newdata2);
curl_exec ($ch);
// do some checking here
curl_close ($ch);
}
?>
Sample input:
$site = 'http://www.mysite.com/folder1/folder2/';
$id = 512522;
$newdata = 'Short string here';
$newdata = 'Another short string here with numbers';
Here the main process of updateme.php
if (!$id = intval(Tools::getValue('id')))
$this->_errors[] = Tools::displayError('Invalid ID!');
else
{
$history = new History();
$history->id = $id;
$history->changeState($newdata1, intval($id));
$history->id_employee = intval($employee->id_employee);
$carrier = new Carrier(intval($info->id_carrier), intval($info->id_lang));
$templateVars = array('{delivery}' => ($history->id_data_state == _READY_TO_SEND AND $info->shipping_number) ? str_replace('#', $info->shipping_number, $carrier->url) : '');
if (!$history->addWithemail(true, $templateVars))
$this->_errors[] = Tools::displayError('an error occurred while changing status or was unable to send e-mail to the employee');
}
The site will always be changing and each $items will have atleast 20 data inside it so the foreach loop will run atleast 20 times or more depending on the number of data.
The target site will update it's database with the passed variables, it will probably pass thru atleast 5 functions before it is saved to the DB so it could probably take some time too.
My question is will there be a problem with this approach? Will the script encounter a timeout error while going thru the curl process? How about if the $items data is around 50 or in the hundreds now?
Or is there a better way to do this?
UPDATES:
* Added updateme.php main process code. Additional info: updateme.php will also send an email depending on the variables passed.
Right now all of the other site are hosted in the same server.
You can have a php execution time problem.
For your curl timeout problem, you can "fix" it using the option CURLOPT_TIMEOUT.
Since the cURL script that calls updateme.php doesn't expect a response, you should make updateme.php return early.
http://gr.php.net/register_shutdown_function
function shutdown() {
if (!$id = intval(Tools::getValue('id')))
$this->_errors[] = Tools::displayError('Invalid ID!');
else
{
$history = new History();
$history->id = $id;
$history->changeState($newdata1, intval($id));
$history->id_employee = intval($employee->id_employee);
$carrier = new Carrier(intval($info->id_carrier), intval($info->id_lang));
$templateVars = array('{delivery}' => ($history->id_data_state == _READY_TO_SEND AND $info->shipping_number) ? str_replace('#', $info->shipping_number, $carrier->url) : '');
if (!$history->addWithemail(true, $templateVars))
$this->_errors[] = Tools::displayError('an error occurred while changing status or was unable to send e-mail to the employee');
}
}
register_shutdown_function('shutdown');
exit();
You can use set_time_limit(0) (0 means no time limit) to change the timeout of the PHP script execution. CURLOPT_TIMEOUT is the cURL option for setting the timeout, but I think it's unlimited by default, so you don't need to set this option on your handle.
