  • What's the easiest and safest way to record data being inputted by a user on a web site

    - by fred august
    Apologies, this is a tragically simple question that will bore most of you. I need to implement the simplest "leave your email and we'll contact you" web page. The simplest thing I could think of is doing an HTML form which calls a PHP script which appends the data in some file on the server. Easy to implement, but now I'm wondering if it's totally hackable. Is it? Are there obvious better ways that are still simple? thanks f

  • Django & custom auth backend (web service) + no database. How to save stuff in session?

    - by Infinity
    I've been searching here and there, and based on this answer I've put together what you see below. It works, but I need to put some stuff in the user's session, right there inside authenticate. How would I store acme_token in the user's session, so that it will get cleared if they logged out? class AcmeUserBackend(object): # Create a User object if not already in the database? create_unknown_user = False def get_user(self, username): return AcmeUser(id=username) def authenticate(self, username=None, password=None): """ Check the username/password and return an AcmeUser. """ acme_token = ask_another_site_about_creds(username, password) if acme_token: return AcmeUser(id=username) return None ################## from django.contrib.auth.models import User class AcmeUser(User): objects = None # we cannot really use this w/o local DB def save(self): """saving to DB disabled""" pass def get_group_permissions(self): """If you don't make your own permissions module, the default also will use the DB. Throw it away""" return [] # likewise with the other permission defs def get_and_delete_messages(self): """Messages are stored in the DB. Darn!""" return []

  • Using PHP5s SOAP Client to send data to an ASP/.NET based SOAP server.

    - by user325143
    I am trying to write a snippet of PHP to connect to a third party's API via SOAP to enter some data into their database. The API requires me to pass several mandatory fields for every call (username, password, companyid, entitytype) in addition to the mandatory data fields. It also requires me to call the "ValidateEntity" funciton before calling the "CreateEntity" function. Documentation can be found here: http://wiki.agemni.com/Getting_Started/APIs/Database_API I have never worked with SOAP before, so I am very new to this. Here is what I have so far: error_reporting(E_ALL); ini_set('display_errors', '1'); $client = new SoapClient("http://agemni.com/AgemniWebservices/service1.asmx?WSDL", array('trace'=> true)); $options = array( 'username' => "myuser", 'password' => "mypassword", 'companyid' => myID, 'entitytype' => 2 ); $params = array( 'fname' => "John", 'lname' => "Doe", 'phone' => "859-333-3333", 'zip' => "40332", 'area id' => "12345", 'lead id' => "28222", 'contactdate' => "4/10/2010" ); $validate = $client->__soapCall("ValidateEntity", array($params), array($options)); $client->__soapCall("CreateEntity", array($params), array($options)); echo "<pre>"; var_dump($client-> __getLastRequestHeaders()); var_dump($client-> __getLastRequest()); var_dump($client-> __getLastResponseHeaders()); var_dump($client-> __getLastResponse()); var_dump($result); echo "</pre>"; Upon executing this code, I get the following error: Fatal error: Uncaught SoapFault exception: [Client] SOAP-ERROR: Encoding: object hasn't 'objecttype' property in /www/tmp/index-soap.php:24 Stack trace: #0 /www/tmp/index-soap.php(24): SoapClient->__soapCall('ValidateEntity', Array) #1 {main} thrown in /www/stealth/tmp/index-soap.php on line 24 I guess my question is.. am I even going about doing this the right way? I know this is a very broad question, but I appreciate any advice you can give me about making this work. Please let me know if you require more detail. Thanks!

  • How to Automatically Refresh Data on Page Using Ajax on an Interval?

    - by Karnak
    I would like to load an XML file every 30 seconds and display its contents inside an HTML page. So far I know how to load the file, but I don't know how to automatically refresh it and display its updated contents. It would also be great if it did some error checking and if it displayed error.png image when it's not able to load data.xml file. Here is my code: <head> <script> window.XMLHttpRequest { xmlhttp = new XMLHttpRequest(); } xmlhttp.open("GET", "data.xml", false); xmlhttp.send(); loadXMLDoc = xmlhttp.responseXML; f = loadXMLDoc.getElementsByTagName("foo") function buildBar(i) { qux = (f[i].getElementsByTagName("qux")[0].childNodes[0].nodeValue); document.getElementById("displayBar").innerHTML = qux; } </script> </head> <body> <script> document.write("<ul>"); for (var i = 0; i < f.length; i++) { document.write("<li onclick='buildBar(" + i + ")'>"); document.write(f[i].getElementsByTagName("bar")[0].childNodes[0].nodeValue); document.write("</li>"); } document.write("</ul>"); </script> <div id="displayBar"> </div> </body> After searching the internet for a few hours I found many examples on how to do this, but I didn't know how to implement it in my particular case. I am not a programmer, so please be kind. I would really appriciate any help. It would mean a lot.

  • Converting a C++ Checksum function to Java

    - by user1897599
    I'm trying to convert this C++ checksum to Java but for the time being I've failed. What am I doing wrong? What is it supposed to do? It is supposed to return a positive checksum for a buffer in OpenGL Here's the C part. DWORD QuickChecksum(DWORD *data, int size){ if(!data) { return 0x0; } DWORD sum; DWORD tmp; sum = *data; for(int i = 1; i < (size/4); i++) { tmp = data[i]; tmp = (DWORD)(sum >> 29) + tmp; tmp = (DWORD)(sum >> 17) + tmp; sum = (DWORD)(sum << 3) ^ tmp; } return sum; } And here is what I have tried in Java. As far As I know DWORD is 32bit so I use int in a long to get a unsigned int which should be done in java with ? I've been looking at this problem so much now that I've grown blind to it. public static long getChecksum(byte[] data, int size) { long sum, tmp; sum = getInt(new byte[]{data[0], data[1], data[2], data[3]},true) & 0xFF; for(int I = 4; I < data.length; I += 4) { tmp = getInt(new byte[]{data[I],data[I+1],data[I+2],data[I+3]},true) & 0xFF; tmp = (sum >>> 29) + tmp; tmp = (sum >>> 17) + tmp; sum = (sum << 3) ^ tmp; } return sum & 0xFF; } private static int getInt(byte[] bytes, boolean big) { ByteBuffer bb = ByteBuffer.wrap(bytes); return bb.getInt(); } Thank you all for your help!

  • emacs: interactively search open buffers

    - by Data
    Is there a way to search all the open buffers for a particular pattern. C-s interactively searches current buffer. Similarly, is there something, that searches all the open buffers. I know I can use "occur", but "Occur" brings a new buffer and changes/messes the buffer organization.

    - by Data-Base
    Hi, we are building a PHP script that we need at work to create reports in PDFs the reports will be created by using templates from postgrSQL. so far I found that it can be done with the use of php and odt (openoffice) files [http://www.odtphp.com/] (do you have any other suggestions?) now how I can convert the results to PDF so teachers will get the final reports as PDF any tips? the server has no GUI and I want to make it as simple as possible we tried using PHP to PDF directly with FPDF [http://www.fpdf.org/] but it is really a CPU killer! cheers

  • OSGI bundle (or service)- how to register for a given time period?

    - by Alec
    Hello, all! Search did not give me a hint, how can i behave with the following situation: I'd love to have 2 OSGI implementations of the same interface: one is regular, the other should work (be active/present/whatever) on the given time period (f.e for Christmas weeks :)) The main goal is to call the same interface without specifying any flags/properties/without manual switching of ranking. Application should somehow switch implementation for this special period, doing another/regular job before and after :) I'm a newbie, maybe i do not completely understand OSGI concept somewhere, sorry for that of give me a hint or link, sorry for my English. Using Felix/Equinox with Apache Aries.

  • How can i share data/text with other apps that will accept it?

    - by kefs
    I have an app that creates a new data entry in a sqlite db with several columns. I would like to have a simple share button on the final activity so they can share the results (or even a simple text field) with apps that accept it (email, mms, twitter, etc..). I did some reading on ContentProviders but the more I read, the more I'm thinking i'm heading down the wrong path. Any help is appreciated. Thanks!
