This topic has been moved to PHP Applications. http://www.phpfreaks.com/forums/index.php?topic=357747.0 I don't know, it seemed simple but it turns out I don't know what to do.
I was told that storing a photo as a blob was much harder than simply storing a photo's url or directory location...
So... when a file has been selected through the browse-file manager triggered by
<input type="file"...>and the file selected is shown, when a person pusehs "upload" what is supposed to happen? Do I need some kind of FTP client to access the server and place the photo in there? It seems so easy in a way like the built in filemanager in cPanel... What am I missing? Thanks for any help. I need to reach Win server, scan shared folder and find out what is last created file name on this folder, and than copy this file to local folder. BUT main problem is smb, never used it before, and this is what i came up with, but no luck.
require_once('smbclient.php');
$latest = null;
$smbc = new smbclient ('//10.1.1.10/Share/Address Verification/', 'domain\\username', 'password');
if ($handle = opendir($smbc)) {
$latest = null;
while (($cur = readdir($handle) !== false)) {
if ($latest == null || filectime($cur) > filectime($latest)) {
$latest = $cur;
}
}
closedir($handle);
}
return $latest;
please help, returns Warning: opendir() expects parameter 1 to be string
Hello, We've been working on a page that allows users to create their own avatar to be displayed on their page. We can get the script working but the only way to show the image is to save it to a temp folder, we want to just save the string in the database and let the php show this wehen required here are the file http://test.digitaldemocracy.org.uk/test_avatar.php <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="author" content="John Munro, Democratise Ltd" /> <meta name="copyright" content="Democratise Ltd 2010" /> <meta name="description" content="Digital Democracy -" /> <meta name="keywords" content=" add here" /> <meta name="robots" content="index, follow" /> <meta name="revisit-after" content="1 week" /> <meta http-equiv="Page-Exit" content="blendTrans(Duration=0.5)" /> <link rel="SHORTCUT ICON" href="http://www.digitaldemocracy.co.uk/favicon.ico" /> <title>Digital Democracy -</title> <link href="css/site.css" rel="stylesheet" type="text/css" /> <link href="css/basic.css" rel="stylesheet" type="text/css" /> <link rel="stylesheet" href="avatars/avatar.css" type="text/css" /> <script type="text/javascript" src="avatars/avatar.js"></script> <style type="text/css"> /*<![CDATA[*/ <!-- body { background-image: url(images/background_paper.jpg); background-repeat: repeat; } --> /*]]>*/ </style> <script type="text/javascript"> //<![CDATA[ var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-15681567-1']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ?

I am using php for coding. My php code is not able to read the files from /var/tmp folder. If apache itself creates some files in /var/tmp folder then php code is able to read it. Why this permission denied issues are there though full access permissions are given to each file?
I am very new to PHP and haven't wriiten an update program except in the class I took about 4 years ago using MYSQL.
The company I work for is using PDO so I am having a little bit of a learning curve.
I have a table with a checkbox at the end and I want to insert the records from the table into a new file I created called
OPPSHEDT
SHEDORD Order Number 14 Char
SHEDBORD BackOrder Number 2 Char
SHEDPKD Picked Cases 9,0 Decimal
SHEDSHP Shipped Cases 9,0 Decimal
I'm just not sure how to write the update program to read the array of records and run through the loop and insert the items checked. I saw some other examples on here and all over the internet but they were using mysql. I have a copy of the code to create my table below.
I'd appreciate the help if you can.
Thanks.

How to self check what event i am using, my event : <checkout_cart_product_add_after> how to print, i tried : $event = $observer->getEvent()->getName(); Mage::log($event, null, 'logfile.log'); its not printing Hi guys, I want my application to run a triggered process based on time to execute some tasks, what is the best approach? Thanks I found it helpful to configure all my objects in one or several bootstrap scripts. Before doing so, I would often find myself forgetting that I already had written some class which is located deep in some script and recreating it for some other need (granted, composer definitely helped in this regard, but using it wasn't always applicable).
<?php
$c=new Pimple\Container(getMySettings());
$c['pdo'] = function ($c) {
$db = $c['settings']['mysql'];
return new \PDO(bla);
};
$c['foo'] = function ($c) {
return new Foo(
$c->get('pdo')
);
};
$c['bar'] = function ($c) {
return new Bar(
$c->get('foo')
);
};
It is all good until I find myself needing to create some new instance of some class instead of just passing some common instance to whoever needs it.
class Foo
{
private $pdo;
public function __construct(\PDO $pdo)
{
$this->pdo=$pdo;
}
public function getSomething():SomeClass
{
return new SomeClass($this->getAllDataFromDB($GET['id']));
}
}
class SomeClass
{
private $arr;
public function __construct(array $records)
{
foreach($records as $record) {
$arr[]=new SomeOtherClass($record);
}
}
}
I've read that one shouldn't create new objects in a given class's constructor, and while I could instead do so in some class's method and pass the object to the given class's constructor, to me it seems to really be the same thing. The three issues I have with this scenario a Needing to remember that these classes exist as they are hidden deep in some classes. Makes it more difficult to replace one of the classes with some other class in the future. Some duplication of code.Are there other compelling reasons not to do so? Is it worth the effort to do differently? If so, how would you recommend doing so? My thoughts would either to use Pimple's factory() method are create my only factory which also relies on anonymous functions. Maybe something else?
$c['someClass'] = $c->factory(function (array $record, Container $c) {
return new SomeClass($record);
});
Thanks Hello! http://tutudragon3.info/maths_problem_image.php My problem is: I want to get the link to this image...but in .jpg, see what I mean? a file_get_contents of that page gets me some weird binary text and stuff. Is it possible? Thanks ! How can I save an image created on-the-fly on the server? For example, $img = "<img src=ChessImager/ChessImager.php?ds_color=(176,144,112)&ls_color=(224,200,160)&coordinates=on&square_size=$square_size&fen=" . urlencode($fen) . ">"; I can display the diagram, but I want to save these images with PHP. Hi,
I'm a newbie learning web development in my spare time. I've built a LAMP server from scratch on an old PC as a learning exercise and I think the basic install and setup of that is fine as I installed PHPBB previously and that runs and is working. I've backed the server up at that point and restored so everything up to there is pretty much out of the box. I'm now coding my own web pages, so I've setup virtual hosting so I can hit them and start learning PHP, MySQL etc using quite an old book (PHP4 days) so yes things have changed. I've got an issue right at the start with sessions. It's a basic user authorisation exercise setting a session value authorising the user, and then when you click on a link, the authorised user session variable is tested to determine whether the user is allowed to view the page. This is not working and I've worked out what is happening. I can see the first being created containing the authorised user variable, and then a second empty session being created with just the session id. The session folder group is www-data with rwx permissions. The session file owner and group is www-data with rw permissions ...
-rw------- 1 www-data www-data 13 Nov 29 21:29 sess_bgih8hu82plbrvo0f9naledmdd I don't think permissions is the issue as I can read and display the $_SESSIONID in each page – which also confirms different sessions are being used. I'm also seeing the following error in the apache error log when the second page is requested ... [Fri Nov 29 20:58:27.829382 2019] [php7:notice] [pid 1065] [client x.x.x.x:x] PHP Notice: Undefined index: authuser in /var/www/licks/moviesite.php on line 22, referer: http://licksdev.com/moviemain.php There's hardly any code, it's a very basic exercise, but here you go, this is the main page ...
<?php Here is the second page. when I hit this page I get the not authorised error message:

Ubuntu 18.04. Thanks for any help you can give. I'm using the following code to create a folder from a text field and works fine. I would like to upload 3 files in the created folder. <?php // set our absolute path to the directories will be created in: $path = $_SERVER['DOCUMENT_ROOT'] . '/uploads/'; if (isset($_POST['create'])) { // Grab our form Data $dirName = isset($_POST['dirName'])?$_POST['dirName']:false; // first validate the value: if ($dirName !== false && preg_match('~([^A-Z0-9]+)~i', $dirName, $matches) === 0) { // We have a valid directory: if (!is_dir($path . $dirName)) { // We are good to create this directory: if (mkdir($path . $dirName, 0775)) { $success = "Your directory has been created succesfully!<br /><br />"; }else { $error = "Unable to create dir {$dirName}."; } }else { $error = "Directory {$dirName} already exists."; } }else { // Invalid data, htmlenttie them incase < > were used. $dirName = htmlentities($dirName); $error = "You have invalid values in {$dirName}."; } } ?> <html> <head><title>Make Directory</title></head> <body> <?php echo (isset($success)?"<h3>$success</h3>":""); ?> <h2>Make Directory on Server</h2> <?php echo (isset($error)?'<span style="color:red;">' . $error . '</span>':''); ?> <form name="phpMkDIRForm" method="POST" action="<?php echo $_SERVER['PHP_SELF']; ?>"> Enter a Directory Name (Alpha-Numeric only): <input type="text" value="" name="dirName" /><br /> <input type="submit" name="create" value="Create Directory" /> </form> </body> </html> is there a way to save a field in a session or variable while its being inserted into the data base? with out having to select it using another query $mail2 = "INSERT INTO pm SET pm_id = '', (turn pm_id into a $variable or session) WHERE blah blah blah the problem im having is Im creating two rows right after each other where each row is in differant tables and I need them to match ids and I have nothing to compare it to. only option i can think of is making a fast toggle switch or telling my select to grab in order which would work. Hi, I'm not sure if this is the right forum to post this question, but I'll still post it. I'm a newbie programmer, have 1 year experience of php, mysql and html and know how to make a basic website, but I've never actually uploaded the already written code on the internet.So my question is, if you use vertrigo serv and have folders full of php files, what do you do after getting a domain? I read that dreamweaver does that for you, but i also read that it is a closed source software with limitations if you get the free version.The other choice is using FileZilla(which I don't fully understand yet ) i presume.
Is it possible to remember the last created random number with PHP or do I need to make use of MySQL? I want to generate an equation with submit button 1 and echo it out, and then I want the script to calculate the printed out equation with submit button 2. The problem: As soon as I click submit button 2, the numbers change into different random numbers, since the PHP starts scanning from the top of the file again as soon as the second button has been pressed. $gen = $_POST['gen']; $calc = $_POST['calc']; $x1 = random_number (); $x2 = random_number (); $op = random_op (); echo " <form action='' method='POST'> <input type='submit' name='gen' value='Generate' /><br /> <input type='submit' name='calc' value='Calculate' /> </form> "; if ($gen) { echo "$x1 $op $x2 = ? <br /><br />"; } if ($calc) { switch ($op) { case '+' : $row_1 = $x1 + $x2; break; case '-' : $row_1 = $x1 - $x2; break; case '*' : $row_1 = $x1 * $x2; break; case '/' : $row_1 = $x1 / $x2; break; } echo "$x1 $op $x2 = $row_1"; } I could of course insert the generated numbers into the database and fetch it out again, but I was wondering if it's possible to remember the numbers (even when the 2nd submit buttons has been pressed) within PHP as well? thanks. |
