PHP - What Types Of Problems Are Appropriately Solved By Create_function() ?
I searched the forums and the Internet as a whole looking for more information on this, but all I've turned up is a lot of information on /how/ to use create_function(), not /when/ to use it. For instance: http://en.wikipedia.org/wiki/Lambda_calculus
Let me reiterate that I understand how it works in general. However, in several years of PHP programming, even through the development of fairly complex, robust systems, I can only think of one case where I recall creating a dynamic function and even here I feel like it was a design mistake. Of course, I use anonymous functions all the time in JavaScript for callback code. It seems to be used from time-to-time to iterate over and apply transformations to sets, but I don't understand the advantage over foreach() for such a task. So, if someone is so-inclined, would you mind listing a general scenario or two where create_function() is the correct and appropriate solution to the problem? Similar TutorialsEDIT: I solved it! I'm having problems everything is working fine I have an Include code for php and I put a <div> code in it working with css. It comes up on the page just fine the problem is a strange text that shows up on the page, There was other strange text that it was printing out on the page that I deleted but these two character I can't seem to find where they are in the code looked in the html file, css file and php file: }} maybe it's coming from the css file but I don't know. It shows up on the webpage and kind of is in the way of perfection on the leveling of the page. Anyone have this problem? What should I do? Should I move around the include code in the <body> I just don't know could you help me? I'm sure this is just a stupid mistake, but can someone please help me figure it out? I have one page with a dropdown that is populated from our database, I have submit to pull through to the next page but nothing shows up on the next page (app/approval). I've tried adding some echo statments, but they all show up blank. Code: [Select] <? require ('includes/getconfig.inc'); require ('includes/auth.inc'); require ('includes/dbfunctions.inc'); include (dirname(__FILE__).'/../includes/menuhead.inc'); include ('apptable_functions.inc'); $sql="SELECT pol_id, pol_policy_number FROM policies"; $result=myload($sql); $items = count($result); $options=""; for($x=0; $x<=$items; $x++) { $id=$result[$x]['pol_id']; $thing=$result[$x]['pol_policy_number']; $options.="<OPTION VALUE=\"$id\">".$thing; } ?> Select a case number to see the payout approval. <br> <form action="app/approval.php" method='post'> <SELECT NAME=pol_policy_number> <?=$options?> </SELECT> <input name="Submit" type="submit" Value="Submit Policy Number"/> </form> <br> Code: [Select] <? require ('includes/getconfig.inc'); require ('includes/auth.inc'); require ('includes/dbfunctions.inc'); $pol_number = $_POST['pol_policy_number']; echo "$pol_number"; ?> [Edit: Sorry I found my answer by searching for "period", then finding out that it is a string operator, then read about that. Doesn't seem easy to search for ".=" in Google. Thanks] I got some help here earlier, and I can pretty much understand everything, except I don't understand why there is Code: [Select] $recordOptions .= "<option value=\"{$row['id']}\">"; $recordOptions .= " {$row['firstname']} {$row['lastname']}, {$row['gender']}, {$row['dob']}"; $recordOptions .= "</option>\n"; Why does this whole thing break without .= ? I am new to PHP so, sorry if the answer is really obvious. Code: [Select] $recordOptions = ''; $query = "SELECT * FROM people"; $result = mysql_query($query); if(!$result) { $recordOptions = "<option>Error Retrieving Records</option>\n";; } else { while($row=mysql_fetch_assoc($result)) { $recordOptions .= "<option value=\"{$row['id']}\">"; $recordOptions .= " {$row['firstname']} {$row['lastname']}, {$row['gender']}, {$row['dob']}"; $recordOptions .= "</option>\n"; } } ?> <html> <body> <?php echo $confirmMsg; ?><br /> <form action ='' method='post'> I put a snippet up yesterday, and thought it had been solved. It had a typo error, but there is still something wrong. The whole page follows, because it might be easier to see what I am doing. The form successfully inserts a new record OK, but it will not update a record that already exists as is intended. Instead, it always creates another new record. Where can I be wrong? <?php session_start(); // See if logged in member by checking session data if (isset($_SESSION['recid'])) { // Put stored session variables into local php variable $userid = $_SESSION['recid']; $username = $_SESSION['name']; $school = $_SESSION['college']; $payer_email = $_SESSION['payer_email']; $group1 = $_SESSION['group1']; $group2 = $_SESSION['group2']; $group3 = $_SESSION['group3']; $group4 = $_SESSION['group4']; $group5 = $_SESSION['group5']; $group6 = $_SESSION['group6']; } else { ?> <!-- make login box --> <html> <tr> <td> <p> <p> <p></td> </tr> <table style= border align="center" border="1" width="400" height="200"> <td align="center" valign="center">You need to<a href="login_allocate_quiz.php">log in</a>as an administrator to<br /> allocate quizzes to student groups.</td> </table> </html> <?php exit(); } // Set error message as blank upon arrival to page $errorMsg = ""; // Check to see if the form has been submitted if (isset($_POST['equip'])){ //Connect to the database through include include_once "demo_conn.php"; //set variables $equip = $_POST['equip']; $egroup1 = $_POST['egroup1']; $egroup2 = $_POST['egroup2']; $egroup3 = $_POST['egroup3']; $egroup4 = $_POST['egroup4']; $egroup5 = $_POST['egroup5']; $egroup6 = $_POST['egroup6']; //create variables to manipulate filenames in database $lowquip = strtolower($equip); $wordquip = str_replace (" ", "", $lowquip); $bigpic = $wordquip.'big'; $smallpic = $wordquip.'small'; $bigpic = $bigpic.'.jpg'; $smallpic = $smallpic.'.jpg'; $errorMsg = '<font size="-1"><u>ERROR:</u> You have not entered the following required information.'; $nogroup = ((!$egroup1) && (!$egroup2) && (!$egroup3) && (!$egroup4) && (!$egroup5) && (!$egroup6)); $noequip = (!$equip); if ($nogroup) {$errorMsg .= "--- Student Group.

<h2><a href='viewthread.php?id='{$row['id']}'> {$row['Title']} </a></h2> Post {$row['id']}<br>
If I set the query to an ID that exists the page loads fine $query = mysqli_query($conn, "SELECT * FROM Threads where id='156'") however if I set the id to the GET command the page doesn't load (which should've got the id) $query = mysqli_query($conn, "SELECT * FROM Threads where id=$_GET['id']") I tried casting this to a variable first too $Number = "$_GET['id']" $query = mysqli_query($conn, "SELECT * FROM Threads where id='$Number'") Edited April 2 by Fishcakes What types of data can the $_SESSION cookie store? Objects? Resources? And how are these stored in text form? Is it possible to define a variable's type at the start of your code? I believe you can "cast" a variable, but can I do something like this... Code: [Select] name string; age integer; gender string; children array; single: boolean; I know some people say PHP is better suited for the web because it is loosely-typed, but I'm anal-retentive and like my structure!! TomTees I have a scenario where users are downloading files from a legacy system and uploading the files into a new system that I am supporting. Many of the files do not have an extension (most are tiffs).
The issue we have is that the new system doesn't know how to open these files (we have them open in a preview window in the new system). I have tried numerous solutions, including finfo_file() and the depreciated mime_content_type() funcitons), but all they seem to return is "application/octet-stream".
Thanks.
This topic has been moved to Application Design. http://www.phpfreaks.com/forums/index.php?topic=353735.0 I've asked this question before but still haven't really figured out how best to implement it, and have found myself hitting another roadblock. I have multiple types of charts (i.e. bar, pie, etc), and various endpoints to access them. I like to keep my routing script uncluttered, and feel the following does so.
$app->get('/chart', function (Request $request, Response $response) {
//List of chart with optional filtering
$this->chartService->index($request->getQueryParams());
return $this->chartResponder->index($response, $index);
});
$app->post('/chart', function (Request $request, Response $response) {
//Create a new chart of type (i.e. bar, pie, etc) specified by type parameter
$chart=$this->chartService->create($request->getParsedBody());
return $this->chartResponder->create($response, $chart);
});
$app->get('/chart/{id:[0-9]+}', function (Request $request, Response $response, $args) {
//View chart of given ID
$chart=$this->chartService->detail((int)$args['id']);
return $this->chartResponder->delete($response, $chart);
});
$app->delete('/chart/{id:[0-9]+}', function (Request $request, Response $response, $args) {
//Delete chart of given ID
$this->chartService->delete((int)$args['id']);
return $this->chartResponder->delete($response, null);
});
$app->post('/chart/{id:[0-9]+}/series', function (Request $request, Response $response, $args) {
//Add a new series to the collection for chart with given ID
$chart=$this->chartService->addSeries((int)$args['id'], $request->getParsedBody());
return $this->chartResponder->update($response, $chart);
});
$app->put('/chart/{id:[0-9]+}/series/{seriesPosition:[0-9]+}', function (Request $request, Response $response, $args) {
//Modify series of given position in the collection for chart with given ID
$chart=$this->chartService->updateSeries((int)$args['id'], (int)$args['seriesPosition'], $request->getParsedBody());
return $this->chartResponder->update($response, $chart);
});
//More endpoints for chart of given ID...
I then created the following service to support the endpoints. Off topic, but is this a service or a controller? My index() method is chart type agnostic. My create() method needs a means to determine what type of chart to create, and does so using the received chart "type" passed in the body to get the applicable repository. All the other methods receive the chart ID in the URL path and use it to first get the chart entity and then get the applicable repository based on the object. All seems good!
<?php

Until... I find myself needing to put non-database related functionality in the repository and violating the single responsibility principle. I am not a complete purist and might be willing to do so, however, there does not appear to be a clean way to inject dependencies in a Doctrine repository. One thought I had was to create specialized services maybe as follows:
$c['chartService'] = function ($c) {
return new ChartService(
$c[EntityManager::class],
[
'bar'=>function ($c) {return new BarChartService($c[EntityManager::class]);},
'pie'=>function ($c) {return new PieChartService($c[EntityManager::class], $c['someOtherObject']);},
//add more types...
]
);
};
class ChartService
{
protected $em, $subServices=[];
public function __construct(\Doctrine\ORM\EntityManager $em, $subServices)
{
$this->em = $em;
$this->subServices = $subServices;
}
public function index(array $params=[]):array {/* no change */}
public function create(array $params):Chart {/* maybe no change */}
public function __call($name, $args) {
$chart=$this->em->getRepository(Chart::class)->find($args[0]);
$subservice=$this->getSubservice($chart);
$args[0]=$chart;
return $subservice->$name(...$args);
}
}
abstract class AbstractSpecificChartService
{
protected $em;
public function __construct(\Doctrine\ORM\EntityManager $em)
{
$this->em = $em;
}
public function __call($name, $args) {
throw new \Exception("Method $name not supported");
}
protected function getSubservice(Chart $chart):self {
//Haven't figured out but can do so if needed.
}
public function delete(Chart $chart):void {
//Include methods common to all charts here
$this->em->remove($chart);
$this->em->flush();
}
protected function helperMethods($foo) {
//If necessary.
}
}
class BarChartService extends AbstractSpecificChartService
{
//Override __construct if necessary
public function updateSeries(Chart $chart, int $position, array $params):Chart {
//Note that Chart and not $id is passed.
//implement code as needed
return $chart;
}
}
So, after this long story, how should I implement this? Thank you Hi all, I'm new to PHP and just looking for any advice anyone might have on the following problem I'm having. I have created a database and tables for registering and logging in users. Each record has three different User Types (or roles): 1, 2 and 3. Once the session has started, I would like to make certain menu items available to certain User Types. I suppose it is some sort of if...elseif statement such as: <?php if($UserType==1) echo {"<p>Menu1</p>"} elseif($UserType==2) echo {"<p>Menu2</p>"} elseif($UserType==3) echo {"<p>Menu3</p>"}; ?> Would anybody be able to point me in the right direction? I'd really appreciate any help at all. I am getting this error: Fatal error: Unsupported operand types. Code: [Select] <?php $new_player_credits = $player_credits + $game_credits; $new_player_exp = $player_exp + $game_exp; ?> I have absolutely no clue why I'm getting the error. Both of my variables are integers. can someone explain to me why PHP returns so many different variants when throwing out visitor info using this piece of code? $ip = gethostbyaddr($_SERVER['REMOTE_ADDR']); here are some examples I have seen recently: planetlab24.gino-research.net.in.tum.de 10.32.64.124 49.129.197.35.bc.googleusercontent.com abts-north-dynamic-142.110.68.182.airtelbroadband.in 173-20-152-84.client.mchsi.com now, obviously i can understand the google one, and a few others. but, given the info and insight on these pages: https://www.php.net/manual/en/function.gethostbyaddr.php , and https://www.php.net/reserved.variables.server , why are the returns so different for different people? why does PHP see all different kinds of things? is the cause the way the user’s server is configured? some identifying info OF the server? and what about reserved IPs? like the “10.xx…” one I listed above? I’ve seen hundreds from that pool, and other blocks of reserved ones, and they have never had alpha-chars included in their captures. it’s always only the IP numbers. there a reason for that? really, all I’m looking for is why I see what I see. anyone help? furthermore, does anyone know if other server-side languages like c#, python, ruby or any js frameworks return different results than PHP ever would? thanks. Hello PHP mates! I am having some doubts and I am going to share them with you so maybe someone can help. Okay, I know how to make signup and login page. And here is the problem. How to make signup page for multiple types of users? For example, type A user has its own signup form, user type B also has its own and same goes for C type of user. How can I make that? Thanks in advance PHP freaks! I'm working on a two-file upload form and want to be able to check the mime types of two filenames in a string variable.
The code below was working when the variable @resume_path contained just one filename. How can I modify this to accommodate two files?
when I echo $resume_path, I get, for example: cover_letter_centerline.doc, cover_letter_ctg.doc
Thanks!
//DO NOT TRUST $_FILES['upfile']['mime'] VALUE !!

friends my url is like this Category=Love&ID=1 now in url if i do something like this Category4637=Hate19203&ID=1 the details are still showing, how can i fix this? if someone type Capegory instead of Category and a wrong category name which do not exist with that id in db send them to index.php? I am in the process of creating a script where only certains video types can be uploaded but at the moment am stuck.
Here is my code -
<?php
$title = isset($_POST['title']) ? $_POST['title'] : null;
$desc = nl2br(isset($_POST['description'])) ? $_POST['description'] : null;
$name = isset($_POST['fullname']) ? $_POST['fullname'] : null;
$email = isset($_POST['email']) ? $_POST['email'] : null;
$country = isset($_POST['country']) ? $_POST['country'] : null;
$video = isset($_FILES['video']);
$videoname = isset($_FILES['video']['name']);
$videotmp = isset($_FILES['video']['tmp_name']);
$videosize = isset($_FILES['video']['size']);
$videotype = isset($_FILES['video']['type']);
$videoacceptable = array(
"video/mp4",
"video/ogg",
"video/quicktime",
);
$videopath = "/videos/";
$videofile = $videopath . $video;
if(isset($_POST['submit'])) {
//ERROR MESSAGES / VALIDATION
if(empty($title)) {
$errors[] = "A title is required";
echo "<style type=\"text/css\"> #title { background-color:#F5A9A9;border:1px solid #DF0101; } </style>";

}

So whats happening is when i go to upload a file, im uploading a .mov file but the error message that pops up is "The file type is not allowed, only allowed .mp4, .ogg and .mov" but the .mov mime is in the videoacceptable array so im a bit stuck at the moment, any know whats the problem?
Hey Guys, How are custom Mime Types achieved? Had a quick search through the forums, and most of the posts relate to mail() questions. Did a google search and found a completely useless article that told me to edit a non-existent text box. Quick example, the file type I want is .WAgame, I got this far before I realised what I was doing didn't make sense. So I looked up mime types, knowing that this file would not exist. if ($_FILES["file"]["type"] != "file/WAgame") { naughty! } Help! Edit: |
