  • Why doesn't this piece of php code work?

    - by Sam Gabriel
    Hey guys, I have a mysql database which stores an id for each picture, as well as the picture's url and its thumbnail url. the thumbnail url is something like thumbs/pic.jpg and the page I'm creating has the folder thumbs in the same place it is created. But when I run this piece of code, nothing shows up: <?php ini_set('display_errors', 'On'); error_reporting(E_ALL | E_STRICT); mysql_connect("localhost", "***", "***") or die(mysql_error()); mysql_select_db("pics") or die(mysql_error()); $results = mysql_query("select id from classpics") or die(mysql_error()); $data=mysql_fetch_array($results); foreach($data as $uno) { echo '<td valign="middle" align="center"><a class="neutral" href="../images.php?id=' . $uno['id'] . '"><img src="'. $uno['thumbs'].'" border="0" /></a></td>'; } ?>

  • Favicon to PNG in PHP

    - by sailtheworld
    I need a PHP script to convert favicons to PNGs while keeping their original dimensions. I know Google has it's secret icon converter - http://www.google.com/s2/favicons?domain=http://facebook.com/ but this converts favicons to 16x16 even if they they were originally larger. So basically I need this, minus the shrinking effect. I've also seen this - http://www.controlstyle.com/articles/programming/text/php-favicon/ but I couldn't get it to work after hours of messing around with it. Basically I am trying to automatically grab the icon for a link that will be as large as possible - automatically 48x48 png based on a URL would be the perfect scenario, but I don't know of any humanly possible way to do this given that no websites happen to keep a 48x48 icon in a publicly accessible spot. Does anybody know of a script/service or have a suggestion? Thanks!

  • PHP MVC Learning Suggestions

    - by Noah Goodrich
    Can someone recommend some good resources for learning about MVC in PHP? It doesn't have to be specific to MVC in PHP. In fact, I'm looking for recommendations of materials that focus on the higher level concepts with examples that could port well to any language so even ASP.net books will be tolerated ;-) Any recommendations for books, websites, blogs, etc would be excellent. UPDATE: I have reviewed the MVC Learning Resources post but all of the references there seemed to be ASP.net specific. I was hoping to gather suggestions that were broader than a single language.

  • paypal IPN php script

    - by pol
    I just realized that my paypal ipn handler in php doesn't work anymore (and I change nothing), I use the sample php script provided by paypal. I tried to isolate the problem by making several test, and at this time I can say that the problem is not the "VERIFIED" or the "INVALID" thing but comes from these lines: [...] fputs ($fp, $header . $req); while (!feof($fp)) { $res = fgets ($fp, 1024); if (strcmp ($res, "VERIFIED") == 0) { // check the payment_status is Completed [...] Anyone know if paypal change something or why it doesn't work? thanks' ps: if I put my code before all the paypal tests (before the line "if (!$fp)") it just works fine

  • jQuery Ajax form submit, to call php login script

    - by Stevie Jenowski
    Thanks for checking out my problem... I'm having trouble submitting a login form via Ajax for a php script to run and return a new set of html items which will be replacing the HTML in #userlinks.... heres what I have so far $("#login_form").submit(function() { return false; }); $('#login_button').click(function(event) { $form = $(this).parent("form"); $.post($form.attr("action"), $form.serialize(), function(data){ $('#userlinks').html(data); }); }); The php script checks for post data of username && password, yet all I'm getting is a page refresh and no changes. Nothing returns unless I turn login_button into a link and change the script a bit... Any help would be appreciated!

  • How to define and work with an array of bits in C?

    - by Eddy
    I want to create a very large array on which I write '0's and '1's. I'm trying to simulate a physical process called random sequential adsorption, where units of length 2, dimers, are deposited onto an n-dimensional lattice at a random location, without overlapping each other. The process stops when there is no more room left on the lattice for depositing more dimers (lattice is jammed). Initially I start with a lattice of zeroes, and the dimers are represented by a pair of '1's. As each dimer is deposited, the site on the left of the dimer is blocked, due to the fact that the dimers cannot overlap. So I simulate this process by depositing a triple of '1's on the lattice. I need to repeat the entire simulation a large number of times and then work out the average coverage %. I've already done this using an array of chars for 1D and 2D lattices. At the moment I'm trying to make the code as efficient as possible, before working on the 3D problem and more complicated generalisations. This is basically what the code looks like in 1D, simplified: int main() { /* Define lattice */ array = (char*)malloc(N * sizeof(char)); total_c = 0; /* Carry out RSA multiple times */ for (i = 0; i < 1000; i++) rand_seq_ads(); /* Calculate average coverage efficiency at jamming */ printf("coverage efficiency = %lf", total_c/1000); return 0; } void rand_seq_ads() { /* Initialise array, initial conditions */ memset(a, 0, N * sizeof(char)); available_sites = N; count = 0; /* While the lattice still has enough room... */ while(available_sites != 0) { /* Generate random site location */ x = rand(); /* Deposit dimer (if site is available) */ if(array[x] == 0) { array[x] = 1; array[x+1] = 1; count += 1; available_sites += -2; } /* Mark site left of dimer as unavailable (if its empty) */ if(array[x-1] == 0) { array[x-1] = 1; available_sites += -1; } } /* Calculate coverage %, and add to total */ c = count/N total_c += c; } For the actual project I'm doing, it involves not just dimers but trimers, quadrimers, and all sorts of shapes and sizes (for 2D and 3D). I was hoping that I would be able to work with individual bits instead of bytes, but I've been reading around and as far as I can tell you can only change 1 byte at a time, so either I need to do some complicated indexing or there is a simpler way to do it? Thanks for your answers

  • PHP: deleting files – permission denied – chmod?

    - by mathiregister
    hi guys, i want to delete files from a directory via php. Somehow my php_errorlog always tells me: [06-Jun-2010 19:38:46] PHP Warning: chmod() [function.chmod]: Operation not permitted in /Users/myname/htdocs/ if ($_POST) { echo "yeah!!!"; print count($_POST['deletefiles']); chmod($path, 0777); //server rights foreach ($_POST['deletefiles'] as $value) { print $value; unlink($path .'/' . $value); } //chmod($path, 0666); //server rights } what am I doing wrong? Thank you

  • PHP Include Paths

    - by Keiron Lowe
    Hi, I'm new to PHP and I'm having a problem when trying to link my CSS files using include. Basically I need my files to link back to a certain directory no matter how far down the file is. I have tried using <?php include $_SERVER['DOCUMENT_ROOT'] . '/sysprogs/required/header.html'; ?> But header.html contains the links to my css files so the directory it ends up looking for the css files in is http://localhost/SysProgs/software/CSS/style.css instead of where I want it to go to which is http://localhost/SysProgs/required/CSS/style.css I hope that made sense and I hope you can help me

  • Are there any open source SimpleTest Test Cases that test PHP SPL interfaces

    - by JW
    I have quite a few objects in my system that implement the PHP SPL Iterator interface. As I write them I also write tests. I know that writing tests is generally NOT a cut 'n paste job. But, when it comes to testing classes that implement Standard PHP Library interfaces, surely it makes sense to have a few script snippets that can be borrowed and dropped in to a Test class - purely to test that particular interface. It seems sensible to have these publicly available. So, I was wondering if you knew of any?

  • is PHP itself transforming into a framework?

    - by Elzo Valugi
    At the beginning PHP was a scripting language. But after the introduction and improvement of OOP I see more and more objects added to the core. They started with SPL which grew a lot, now we have DOMDocument family, DateTime family which should be part of PECL, Pear or Zend Framework or implemented by each one of us. Shouldn't be php only for build-in functions and all these objects passed to something else? Example. DateTime class is part of the core and I see it very similar with Zend_Date.

  • Loading .sql files from within PHP

    - by Josh Smeaton
    I'm creating an installation script for an application that I'm developing and need to create databases dynamically from within PHP. I've got it to create the database but now I need to load in several .sql files. I had planned to open the file and mysql_query it a line at a time - until I looked at the schema files and realised they aren't just one query per line. So, please.. how do I load an sql file from within PHP? (as phpMyAdmin does with it's import command).

  • How to flush data in php and disconnect user but keep the script alive

    - by Rodrigo
    This is a trick question, while developing a php+ajax application i felt into some long queries, nothing wrong with them, but they could be done in background. I know that there's a way to just send a reply to user while throwing the real processing to another process by exec(), however it dosen't feels right for me, this might generate exploits and it's not pratical on making it compatible with virtual servers and cross platform. PHP offers the ob_* functions although they help on flushing the cache, but the user will keep connected until the script is running. I'm wondering if there's an alternate to exec to keep a script running after sending data to user and closing connection/thread with apache, or a less "dirty" way to have processing data sent to another script.

  • Obtaining photo 'stars' rating using PHP

    - by DarwinIcesurfer
    I am trying to extract the photo 'stars' rating from .jpg files using php code. My intent is to show the highest rated images as part of a slideshow. I found that using the PHP_JPEG_Metadata_Toolkit_1.11 I am able to get the rating of the file if the rating is set from within Vista (Right click - Properties - Details - Set rating by clicking on stars) by reading the array returned by the Metadata_Toolkit $exif = get_EXIF_JPEG( $photodir . "/" . $filename ); $rating = $exif[0][18246]['Data'][0]; However if I set the rating using Adobe Bridge, I can see the 'stars' in Vista, but the $exif[0][18246]['Data'][0] returns a null value. Is PHP code available to read the ratings applied by both Windows Vista AND Adobe Bridge?

  • MySQL PHP incompatibility.

    - by Evernoob
    Ok maybe I've overlooked something really simple here, but I can't seem to figure this out. I'm running WAMP locally, but connecting to a remote MySQL database. The local version of PHP is the latest 5.3.0. One of the remote databases, being version 5.0.45 works fine. However, the other remote database I'm trying to connect to, which is version 5.0.22 throws the following error before dying: Warning: mysql_connect() [function.mysql-connect]: OK packet 6 bytes shorter than expected. PID=5880 in ... Warning: mysql_connect() [function.mysql-connect]: mysqlnd cannot connect to MySQL 4.1+ using old authentication in ... WTF? UPDATE: Reverting to PHP 5.2.* i.e. anything lower than 5.3.0 resolves the problem completely. As long as I am not running 5.3.0 I can connect to both databases. I'm not sure what the explanation is for this weirdness.

  • php mail function cannot send to [email protected] ??i

    - by user333216
    I'm having trouble when sending emails thorough the mail() function. I have a script that works perfectly fine for an email address like [email protected] but when the first part of the email is something with a dot like [email protected] it doesn't work and returns this error : Warning: mail() [function.mail ]: SMTP server response: 554 : Recipient address rejected: Relay access denied in confirmed.php on line 119 I am using real email address but have changed it in the above example. Any thoughts - I'm not a php master but surely there is an easy way to send emails to address with a 2 part first section?? Thanks in advance Ali

  • Problem passing variables in php form.

    - by Joshxtothe4
    I have the following php form. I am trying to make it so that when the form is loaded, the values will be assigned the appropriate check- variable. This variable will contain either "checked or "". If it contains checked, the way it is displayed with the html should cause the relevant checkbox to be checked. As it is, the variables do not seem to be being passed. When I echo out $deleted or $notice from within the submitinfo branch, they are blank. Furthermore, nothing is being inserted into the database, and I am not getting any database error. How can I check this? <?php if (isset($_GET["cmd"])) $cmd = $_GET["cmd"]; else if (isset($_POST["cmd"])) $cmd = $_POST["cmd"]; else die("Invalid URL"); if (isset($_GET["pk"])) { $pk = $_GET["pk"]; } if (isset($_POST["deleted"])) { $deleted = $_POST["deleted"]; } if (isset($_POST["notice"])) { $notice = $_POST["notice"]; } $con = mysqli_connect("localhost","user","password", "db"); if (!$con) { echo "Can't connect to MySQL Server. Errorcode: %s\n". mysqli_connect_error(); exit; } $con->set_charset("utf8"); $getformdata = $con->query("select * from STATUS where ARTICLE_NO = '$pk'"); $checkDeleted = ""; $checkNotice = ""; while ($row = mysqli_fetch_assoc($getformdata)) { $checkDeleted = $row['deleted']; $checkNotice = $row['notice']; } if($cmd=="submitinfo") { $statusQuery = "INSERT INTO STATUS VALUES (?, ?)"; if ($statusInfo = $con->prepare($statusQuery)) { $statusInfo->bind_param("ss", $deleted, $notice); $statusInfo->execute(); $statusInfo->close(); echo "true"; } else { echo "false"; } print_r($con->error); } if($cmd=="EditStatusData") { echo "<form name=\"statusForm\" action=\"test.php\" method=\"post\" enctype=\"multipart/form-data\"> <h1>Editing information for auction: ".$pk."</h1> Löschung Ebay: <input type=\"checkbox\" name=\"deleted\" value=\"checked\" ".$checkDeleted." /> <br /> Abmahnung: <input type=\"checkbox\" name=\"notice\" value=\"checked\" ".$checkNotice." /> <br /> <input type=\"hidden\" name=\"cmd\" value=\"submitinfo\" /> <input name=\"Submit\" type=\"submit\" value=\"submit\" /> </form>"; } else { print_r($con->error); }
