PHP - Get An Image Created By Php
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 ! Similar TutorialsI 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 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. 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 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.
Hey, I'm writing an application that tracks attendance. There are multiple events ('events' table), in which members that are present will be found. (When an event file is uploaded, it has all members that attended the event, and adds the event entry in 'events', as well as adding each member to the 'attendance' table, with event_id(eid) and the 'did_attend' value as '1'. When the event is edited, it needs to find the other members that AREN'T in the events table, and add them to the 'attendance' table. When I use this code, it apparently keeps adding the same members. Will a LIMIT 1 stop this? I has about 65,000+ entries added before I stopped the execution of the script. Thanks! Code: [Select] $sql2 = mysql_query("SELECT * FROM members WHERE status=1 ORDER BY mid ASC"); while($row = mysql_fetch_assoc($sql2)){ $sql3 = mysql_query("SELECT * FROM attendance WHERE event='$eid' ORDER BY member ASC"); while($row2 = mysql_fetch_assoc($sql3)){ if($row2[mid] == $row[mid]){ // if the member is in the attendance db, skip }else{ //if member is not in attendance, write zero--- causing multiple entries (50,000+) $qry = mysql_query("INSERT INTO attendance (member,event,did_attend) VALUES ('$row[mid]','$eid','0')"); if(!$qry){ die("SQL: ".mysql_error()); }else{ $msg = "<br />Member ".$row[mid]." marked as absent."; } } } } I have heard there is a way to convert an html document to pdf with fpdf. I will need to pull information from a database though so it will be a php file instead. Does anyone know of a way to convert a php output to pdf in the same way? 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 .

Below is a short script of two buttons created with php, how can I use the buttons to link to a new web page (similar to using "href" in html)? I would like to use the php created buttons to keep the general look and feel to my site the same through. In advance, thank you for the support... This is the part in my normal page that shows the buttons: echo "<form action='processButtonsDdr.php' method='POST'> <input type='submit' name='display_button' value='homepage' /> <input type='submit' name='display_button' value='new entry' /> This is a snippet from my two button process page: <?php if($_POST['display_button'] == "home page") { ????????????????? // what do I enter in this area to point the button to another webpage? } else { ????????????????? } ?> 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');

Hi all I have a form with a few textareas and a bunch of input fields. The input fields are dynamically created from querying a country table. $query = $DB->query("SELECT country_code, country_id, IF(country_code = '".$country_code."', '', '') AS sel FROM countries WHERE site = 'test' ORDER BY country_name ASC"); foreach ($query->result as $row) { $options .= '<label>' . 'Phrase for ' . $this->settings['countries'][$row['country_code']] . '</label>' . '<br />'; $options .= '<input style="width: 100%; height: 5%;" id="country_data" type="text" name="' . $row['country_id'] . '" />' . '<br /><br />'; $options .= '<input type="hidden" name="country_id" id="country_id" value="' . $row['country_id'] . '" />'; } This is fine and outputs all the input fields I need. The problem comes when I need to get the value of each field input field and pass it into a query. The 'value' field of the inputs are numbers, such as 68, 70, 124, 108 etc so I can't get them in a for loop etc What's the easiest way to get all of these input field values? Can I use $_POST? I have the following code which displays images and captions from a directory. I would like the images to be displayed in the order they were created. Somebody suggested I use glob(), but I have no idea how. <?php $dir = "exclusive_images/"; if ($opendir = opendir($dir)) { //read directory while(($file = readdir($opendir)) !==FALSE) { if ( file_exists($dir.'/'.$file) && in_array( strtolower(pathinfo($file,PATHINFO_EXTENSION )), array('png','jpg','jpeg','gif'))) { if (file_exists($dir.'/'.$file. '.txt')) $caption = file_get_contents($dir.'/'.$file. '.txt'); else $caption = ucwords(str_replace(array('-','_'),' ', substr($file, 0, (strlen ($file)) - (strlen (strrchr($file,'.')))))); echo '<tr><td><img src="' . $dir.'/'.$file .'" alt="'. $file .'" title="' . $file . '" width="200"></td><td>' . $caption . '</td></tr>'; } } } ?> 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. 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 trying to make a gallery, and it more or less works. But I don't like having to load so many images for the user to view.
What happens is I have a very basic method of loading the images into the index file using require.
<?php
foreach (glob("*.jpg") as $filename) {
echo "<div class='itemContainer'><img src='" . $filename . "' class='item' id='" . $filename . "' /></div>";
}
?>
Pretty simple. but it just loads everything in the directory. What I'd like to do is make it so 30 images load, and then it creates a new "div container" and loads the next 30 in. As well as a page counter, and a next and previous button.
I'm not too sure how to control the flow of information from PHP to the index file when using require. Or if this is even the right way of doing it.
My thoughts are sorta like this
$imageCounter = 0;
$newPageStandard = 30;
foreach($imageDir as $image){
// echo image;
$imageCounter++
if($imageCounter == $newPageStandard){
$newPageStandard += $newPageStandard; // increase standard for next page if there are enough images
//create new image container(div)
//somehow re-direct the echo into this new image container
}
// continue echoing images
}
Something Along those lines. Is this at all on the right path, or should I be grabbing all the images, and stuffing them into an multidimensional array and breaking each array into segments of 30? Or perhaps another completely different method? (yeah I dont have a clue what Im doing atm)
Edited by 7blake, 10 November 2014 - 06:37 AM. I'm trying to create a table form that pulls in "Extra" choices from a table and allows users to select a number of days and number of guests for each choice. I started creating it a a checkbox field but am thinking just using the name as a label and setting days and guests to default "0" might be a better bet. Guidance from someone more experienced with this? Also, how do I store the submission (db structure - in the "reservations" table, another?). I'm new to this and feel kind of lost with this challenge. //Extras $query = "select * from extras"; $data = mysqli_query($db, $query); $num = mysqli_num_rows($data); echo "<p><b>Extras:</b></p>"; for ($i=0; $i<$num; $i++) { $row = mysqli_fetch_array($data); $extra_id = $row['extra_id']; $extra_name = $row['extra_name']; $extra_rate = $row['extra_rate']; echo "<p><input type='checkbox' name='extra_id[]' value = '$extra_id' />$extra_name <i>\$$extra_rate</i> Num Days<input type='text' name='d$extra_id' /> Num Guests<input type='text' name='g$extra_id' />"; } Hi, I've written a script for a client which creates a folder on the server using mkdir. The client wanted this folder to be created for them (don't ask why, it's complicated!), then they wanted to be able to FTP in and add files into the folder using FTP. The problem is that the script creates the file with a group of 99. When the client tries to FTP in and add their files, they get the following error: '550 Can't create directory: Permission denied', presumably because they're in a different group. What I need to be able to do is get the script to create a folder with a different group, so that my client can FTP their files into it. I thought I would be able to use PHP's chgrp after mkdir, as follows: mkdir($filepath, 0777) chgrp($filepath, 501); However then I get "Warning: chgrp() [function.chgrp]: Operation not permitted". I realise from reading the manual that I need to be a superuser to do this, which my web script obviously isn't. My question is, how can I get around this? Is there some setting in Apache that I can set? Thanks in advance for any help! Willo I haven't worked with TCPDF yet (PHP class for creating PDFs) but if anyone has, I'm just curious if you can reference an external CSS file to format the HTML that gets created in the PDF? Or can you only use inline CSS? Basically, I have a nicely formatted HTML table using a somewhat complicated external CSS file and I want to output that same table to a PDF and have it look essentially the same. If TCPDF cannot do this, do you know of any other PDF PHP libraries that can? Thanks, Greg my name is fairooj and ama new to php and jquery. i have a proplam. i want your help.
