  • How can I split a PHP form into two sections, before submission to a database?

    - by Daniel Smith
    Hi guys, I have set up a PHP form for a competition, for users to enter and all information to be stored in a database. I used the following NetTut+ tutorial to do so: http://tr.im/SwAd. I've got the form submitting to the database as required, but with so many additional questions being asked, I would like to split the form into two separate sections. Obviously the first page would say continue to the next step before the second step allowing for the form to be submitted to the database. The content that the user sees should be split, but should all be a part of the same form. Step 1 Step 2 before submission. Would anyone know of or recommend any methods to do this? I'm a beginner so please be nice. :) Cheers, Daniel

  • What are some good ways to store performance statistics in a database for querying later?

    - by Nathan
    Goal: Store arbitrary performance statistics of stuff that you care about (how many customers are currently logged on, how many widgets are being processed, etc.) in a database so that you can understand what how your servers are doing over time. Assumptions: A database is already available, and you already know how to gather the information you want and are capable of putting it in the database however you like. Some Ideal Attributes of a Solution Causes no noticeable performance hit on the server being monitored Has a very high precision of measurement Does not store useless or redundant information Is easy to query (lends itself to gathering/displaying useful information) Lends itself to being graphed easily Is accurate Is elegant Primary Questions 1) What is a good design/method/scheme for triggering the storing of statistics? 2) What is a good database design for how to actually store the data? Example answers...that are sort of vague and lame... 1) I could, once per [fixed time interval], store a row of data with all the performance measurements I care about in each column of one big flat table indexed by timestamp and/or server. 2) I could have a daemon monitoring performance stuff I care about, and add a row whenever something changes (instead of at fixed time intervals) to a flat table as in #1. 3) I could trigger either as in #2, but I could store information about each aspect of performance that I'm measuring in separate tables, opening up the possibility of adding tons of rows for often-changing items, and few rows for seldom-changing items. Etc. In the end, I will implement something, even if it's some super-braindead approach I make up myself, but I'm betting there are some really smart people out there willing to share their experiences and bright ideas!

  • boost::shared_ptr in Objective-C++

    - by John Smith
    This is a better understanding of a question I had earlier. I have the following Objective-C++ object @interface OCPP { MyCppobj * cppobj; } @end @implementation OCPP -(OCPP *) init { cppobj = new MyCppobj; } @end Then I create a completely differently obj which needs to use cppobj in a boost::shared_ptr (I have no choice in this matter, it's part of a huge library which I cannot change) @interface NOBJ -(void) use_cppobj_as_shared_ptr { //get an OCPP obj called occ from somewhere.. //troubling line here } @end I have tried the following and that failed: I tried synthesising cppobj. Then I created a shared_ptr in "troubling line" in the following way: MyCppobj * cpp = [occ cppobj]; bsp = boost::shared_ptr<MyCppobj>(cpp); It works fine first time around. Then I destroy the NOBJ and recreate it. When I for cppobj it's gone. Presumably shared_ptr decided it's no longer needed and did away with it. So I need help. How can I keep cppobj alive? Is there a way to destroy bsp (or it's reference to cppobj) without destroying cppobj?

  • Grouping php array items based on user and created time

    - by Jim
    This is an array of objects showing a user uploading photos: Array ( [12] => stdClass Object ( [type] => photo [created] => 2010-05-14 23:36:41 [user] => stdClass Object ( [id] => 760 [username] => mrsmith ) [photo] => stdClass Object ( [id] => 4181 ) ) [44] => stdClass Object ( [type] => photo [created] => 2010-05-14 23:37:15 [user] => stdClass Object ( [id] => 760 [username] => mrsmith ) [photo] => stdClass Object ( [id] => 4180 ) ) ) However instead of showing: mr smith uploaded one photo mr smith uploaded one photo I'd like to display: mr smith uploaded two photos by grouping similar items, grouping by user ID and them having added them within, let's say 15 minutes of each other. So I'd like to get the array in this sort of shape: Array ( [12] => stdClass Object ( [type] => photo [created] => 2010-05-14 23:36:41 [user] => stdClass Object ( [id] => 760 [username] => mrsmith ) [photos] => Array ( [0] => stdClass Object ( [id] => 4181 ) [1] => stdClass Object ( [id] => 4180 ) ) ) ) preserving the first item of the group and it's created time, and supplementing it with any other groupable photos and then unsetting any items that were grouped (so the final array doesn't have key 44 anymore as it was grouped in with 12). The array contains other actions than just photos, hence the original keys of 12 and 44. I just can't figure out a way to do this efficiently. I used to use MySQL and PHP to do this but am trying to just use pure PHP for caching reasons. Can anyone shed any insights? I thought about going through each item and seeing if I can group it with the previous one in the array but the previous one might not necessarily be relevant or even a photo. I've got total brain freeze :(

  • Why won't SWFUpload execute the upload.aspx code, and why is it saving all files to the root directo

    - by Nathan Fast
    I am using SWFUpload v2.2. In IE (8):   If I upload a very tiny file (16kb):      1) The file appears in the root directory where upload.aspx is located.      2) Page_Load on upload.aspx.cs is executed.      3) The file is actually processed by the Page_Load procedure, and the processed file is saved in the correct location.   If I upload a normal file (1.5 MB):      1) The file appears in the root directory where upload.aspx is located. In Firefox (3.5.7):   No matter what size the file is, it:      1) The file appears in the root directory where upload.aspx is located. I have maxRequestLength="30000" executionTimeout="3000" in the web.config just to be sure. In the setting object for the constructor I have:   file_size_limit: "10 MB",   file_types: ".",   file_types_description: "All Files", So my questions are:   How is the file getting saved in the root directory (and why)?   Why does Page_Load only execute when I am using IE and uploading very tiny files?

  • Prevent find from printing .git folders

    - by Nathan Neff
    I have a find command that I run, to find files named 'foo' in a directory. I want to skip the ".git" directory. The command below works except it prints an annoying ".git" any time it skips a .git directory: find . ( -name .git ) -prune -o -name '*foo*' How can I prevent the skipped ".git" directories from printing to stdout?

  • Use a non-coalescing parser in Axis2

    - by Nathan
    Does anyone know how I can get Axis2 to use a non-coalescing XMLStreamReader when it parses a SOAP message? I am writing code that reads a large base64 binary text element. Coalescing is the default behaviour, and this causes the default XMLStreamReader to load the entire text into memory rather than returning multiple CHARACTERS events. The upshot of this is that I run out of heap space when running the following code: reader = element.getTextAsStream( true ); The OutOfMemory error occurs in com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl.next: java.lang.OutOfMemoryError: Java heap space at com.sun.org.apache.xerces.internal.util.XMLStringBuffer.append(XMLStringBuffer.java:208) at com.sun.org.apache.xerces.internal.util.XMLStringBuffer.append(XMLStringBuffer.java:226) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanContent(XMLDocumentFragmentScannerImpl.java:1552) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDriver.next(XMLDocumentFragmentScannerImpl.java:2864) at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.next(XMLDocumentScannerImpl.java:607) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.next(XMLNSDocumentScannerImpl.java:116) at com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl.next(XMLStreamReaderImpl.java:558) at org.apache.axiom.util.stax.wrapper.XMLStreamReaderWrapper.next(XMLStreamReaderWrapper.java:225) at org.apache.axiom.util.stax.dialect.DisallowDoctypeDeclStreamReaderWrapper.next(DisallowDoctypeDeclStreamReaderWrapper.java:34) at org.apache.axiom.util.stax.wrapper.XMLStreamReaderWrapper.next(XMLStreamReaderWrapper.java:225) at org.apache.axiom.util.stax.dialect.SJSXPStreamReaderWrapper.next(SJSXPStreamReaderWrapper.java:138) at org.apache.axiom.om.impl.builder.StAXOMBuilder.parserNext(StAXOMBuilder.java:668) at org.apache.axiom.om.impl.builder.StAXOMBuilder.next(StAXOMBuilder.java:214) at org.apache.axiom.om.impl.llom.SwitchingWrapper.updateNextNode(SwitchingWrapper.java:1098) at org.apache.axiom.om.impl.llom.SwitchingWrapper.<init>(SwitchingWrapper.java:198) at org.apache.axiom.om.impl.llom.OMStAXWrapper.<init>(OMStAXWrapper.java:73) at org.apache.axiom.om.impl.llom.OMContainerHelper.getXMLStreamReader(OMContainerHelper.java:67) at org.apache.axiom.om.impl.llom.OMContainerHelper.getXMLStreamReader(OMContainerHelper.java:40) at org.apache.axiom.om.impl.llom.OMElementImpl.getXMLStreamReader(OMElementImpl.java:790) at org.apache.axiom.om.impl.llom.OMElementImplUtil.getTextAsStream(OMElementImplUtil.java:114) at org.apache.axiom.om.impl.llom.OMElementImpl.getTextAsStream(OMElementImpl.java:826) at org.example.UploadFileParser.invokeBusinessLogic(UploadFileParser.java:160)

  • IOS where to put the configuration of facebook sdk

    - by Carol Smith
    I am trying to integrated my IOS 7 application with Facebook SDK I following this official tutorial https://developers.facebook.com/docs/ios/getting-started which states Configure the .plist Follow these three steps: Create a key called FacebookAppID with a string value, and add the app ID there. Create a key called FacebookDisplayName with a string value, and add the Display Name you configured in the App Dashboard. Create an array key called URL types with a single array sub-item called URL Schemes. Give this a single item with your app ID prefixed with fb. This is used to ensure the application will receive the callback URL of the web-based OAuth flow. The finished .plist should look something like this: My question is where to put these values? They already put this image, maybe it helps you to answer me Edit The problem that I don't have any plist file in my framework in xcode and I can't add a new one because if i did, I would have to add all the variables that you see in the image but the tutorial just stated about some of them

  • C# dictionary and lookup add / update

    - by freddy smith
    I am sick of doing blocks of code like this for various bits of code I have: if (dict.ContainsKey[key]) { dict[key] = value; } else { dict.Add(key,value); } and for lookups (i.e. key - list of value) if (lookup.ContainsKey[key]) { lookup[key].Add(value); } else { lookup.Add(new List); lookup[key].Add(value); } Is there another collections lib or extension method I should use to do this in one line of code no matter what the key and value types are? e.g. dict.AddOrUpdate(key,value) lookup.AddOrUpdate(key,value)

  • SVN Serve, Missing a Directory

    - by Ryan Smith
    I'm sure this is an asinine question, and I blame myself for not fully understanding how the SVNSERVE process works. I have an SVN repo, but it needs to be moved to a server within a clients cloud. I did this a while back and ran into the issue of the SVNSERVE.exe process not getting set to the right directory. I have the SVNSERVE.exe process running as a windows service and pointing to the right directory. There are two other repos there that are serving out fine in the same directory. I copied out the new directory just like I did with the others, but I'm getting the error "No repository found". I thought that SVNSERVE just looked at that directory and served out the repositories that were there, but I have had a hard time finding more information about that. I thought it was a Windows permission problem, but I set the whole folder to be full control to EVERYONE, so that's not it. I feel horrible I didn't fully understand this problem the first time I fought it, but it's late on a Sunday night and clients are yelling. Anyone know what I'm missing? Thanks. EDIT: It's specific to the repository. I tested the same process with some of the other repos we have on our server and when I copied them up, they worked just as expected. This bug is breaking me and I wish I could provide more details, but that's all I know. I'm going to try to do an SVN Dump instead of an XCopy and see how that goes. I'll let you know.

  • Should I invest time in learning about OR\M or LINQ?

    - by Peter Smith
    I'm a .NET web developer primarily who occasionally writes console applications to mine data, cleanup tasks, etc. Most of what I do winds up involving a database which I currently design via sql server management studio, using stored procedures, and query analyzer. I also create a lot of web services which are consumed via AJAX applications. Do these technologies really help you in speeding up development times? Do you still have to build the database or object code first?

  • Need to work out database structure

    - by jim smith
    Hi, Just need a little kickstart with this. I have Mysql/PHP, and I have 5,000 products. I have 30 companies I need to store some data for those 30 companies for each product as follows: a) prices b) stock qty I also need to store data historically on a daily basis. So the table... It makes sense that the records will be the products because there's 5000, and if I put the companies as the columns, I can store the prices, but what about the stock quantities? I could create two columns for each compoany, one for prices, one for qty. Then make the tablename the date for that day...so theer would be a new table for every day with 5000 products in it? is this the correct way? Some idea on how I'll be retreiving data the top 5 lowest prices (and the company) by product for a certain date the price and stock changes in the past 7 days by product

  • Chart for deciphering terms in different programming languages

    - by Nathan Adams
    This has been bugging me every since I started to use Python - in PHP you have this ability to use a string as a key in an array. PHP calls these associative arrays. Python calls these dictionaries. Does anyone know of a premade chart that will let me see what the different terminology is in different languages. For example: PHP             | Python Assosicative array | Dictionary

  • Push or Pull to Excel for reporting data

    - by Nathan Fisher
    I am unsure which is the best way to go here. I have a third party Excel 2003 spreadsheet that needs to be filled in on a monthly basis and emailed. Currently it is a manual process and I am in the process of automating the generation of the spreadsheet. I have been throwing around different ideas of how to get the data into the spreadsheet. I have thought of using SSRS to create a report that is in a similar format and get the user to cut and past. Alternatively writing a VBA addin that retrieves that data from a webservice and then adds the data to the spreadsheet. Or using the third party spreadsheet as a template and open it on the server via oledb and adding the data then serving it as a downloadable file. Which is better or are the better solutions out there?

  • Placement of command line options in bash

    - by Nathan Rambeck
    I just starting using a Mac and have been frustrated that command line options are required immediately following the command so that this works: ls -la /usr but this doesn't: ls /usr -la ls: -la: No such file or directory Is there any way to change this? Or can someone tell me why the placement of options is agnostic on most Linux platforms, but not on Mac?

  • Flash uploader that can handle >2GB files?

    - by Alvin SMith
    Is there an open source Flash uploader that can handle files larger than 2 GB? ASP.net implementations like SlickUpload are not an option, and SWFUpload (and others that I've seen) do not handle files larger than 2 GB. Nor is requiring the user to have Java installed to run applets. This would be for both IE and Firefox. I've seen a couple "large file transfer" sites that have a Flash uploader and claim to go past the 2GB limit (which is the limit for http uploads for most browsers) so I know it is technically possible.

  • Is there any way to disable Erubis from printing "** Erubis 2.6.5" when starting the Rails environme

    - by Nathan
    I have several frequent Cron jobs that are run via Rake and the output of those jobs are e-mailed (via a MAILTO). Due to the fact that these tasks load the Rails environment (which includes Erubis) they always prints out "** Erubis 2.6.5" on startup. This means that an e-mail is always generated since Cron receives output. Is there any way to configure Erubis to cease printing this startup message to the console?

  • PHP: Next Available Value in an Array, starting with a non-indexed value

    - by Erik Smith
    I've been stumped on this PHP issue for about a day now. Basically, we have an array of hours formatted in 24-hour format, and an arbitrary value ($hour) (also a 24-hour). The problem is, we need to take $hour, and get the next available value in the array, starting with the value that immediately proceeds $hour. The array might look something like: $goodHours = array('8,9,10,11,12,19,20,21). Then the hour value might be: $hour = 14; So, we need some way to know that 19 is the next best time. Additionally, we might also need to get the second, third, or fourth (etc) available value. The issue seems to be that because 14 isn't a value in the array, there is not index to reference that would let us increment to the next value. To make things simpler, I've taken $goodHours and repeated the values several times just so I don't have to deal with going back to the start (maybe not the best way to do it, but a quick fix). I have a feeling this is something simple I'm missing, but I would be so appreciative if anyone could shed some light. Erik
