  • SQL returns non-array value in PHP

    - by DeadMG
    $request = 'SELECT * FROM flight WHERE Id = \''.$_SESSION['LFLightRadio'].'\''; $data = mysql_fetch_array(mysql_query($request, $SQL)); echo '<table class="table">'; foreach($data as $key => $value) { echo '<th class="head" align="center" height="19">'.$key.'</th>'; } echo '<tr>'; foreach($data as $key => $value) { echo '<td class="cell" align="center" height="19">'.$value.'</td>'; } echo '</tr></table>'; I know that the LFlightRadio value is set, and is a value returned by the Id value of a previously returned row from the flight database. So within "flight", a record definitely exists with this Id. But, this still gives me a non-array result, so that when I try to use foreach on it, it errors out. Suggestions?

  • seo value of duplicating content externally

    - by Don
    I run a website that includes a blog which was hand-coded by myself and is hosted on the same domain. My partner in this endeavour thinks it would be a good idea to open up a blogger/wordpress blog and duplicate the on-site blog on this off-site blog. AFAIK the main reason for doing this is the SEO benefits of the inbound links that this off-site blog will create. I think this is a bad idea, because: Effectively what we're doing is creating a (very small scale) link farm We're more likely to be punished than rewarded (in SEO terms) for duplicating our content across domains This introduces a problem of synchronising our content across domains. For example, if a blog post is edited on the on-site blog, then ideally the off-site blog should be similarly updated. I know very little about SEO, so would be interested to hear what more informed readers have to say.

  • PHP: Safe way to store decryptable passwords

    - by Jammer
    I'm making an application in PHP and there is a requirement that it must be possible to decrypt the passwords in order to avoid problems in the future with switching user database to different system. What encryption/decryption algorithm would you suggest? Is it good idea to just store the encrypted value and then compare the future authentication attempts to that value? Are the passwords still as safe as MD5/SHA1 when the private key is not available to the attacker (Hidden in USB drive for example)? I should still use salting, right? What encryption libraries should I use for PHP?

  • Store children in database preserving information about their order

    - by GUZ
    I am designing database tables for a master-detail scenario. The specific requirement is that it is necessary to store information about the order of children. I see some possible solutions (like adding a column representing a position in the sequence, or a column with foreign key to the previous child) but I would like to know the best practices how to solve such problems. Best regards Lukasz Glaz

  • App store for the PC?

    - by Chris
    So I've spent a lot of time making an iPhone game and have recently realized that I don't have to limit myself to just Apple - I know there are app stores for Palm and Android, but does anybody know of a good "app store" for the plain old PC? I would like to have one where individual developers can publish an app and not have to worry about all the billing and piracy issues!

  • Not getting key value from Identity column back after inserting new row with SubSonic ActiveRecord

    - by mikedevenney
    I'm sure I'm missing the obvious answer here, but could use a hand. I'm new to SubSonic and using version 3. I've got myself to the point of being able to query and insert, but I'm stuck with how I would get the value of the identity column back after my insert. I saw another post that mentioned Linq Templates. I'm not using those (at least I don't think I am...?) TIA ... UPDATE ... So I've been debugging through my code watching how the SubSonic code works and I found where the indentity column is being ignored. I use int as the datatype for my ID columns in the database and set them as identity. Since int is a non-nullable data type in c# the logical test in the Add method (public void Add(IDataProvider provider)) that checks if there is a value in the key column by doing a (key==null) could be the issue. The code that gets the new value for the identity field is in the 'true path', since an int can't be null and I use ints as my identity column data types this test will never pass. The ID field for my object has a 0 in it that I didn't put there. I assume it's set during the initialization of the object. Am I off base here? Is the answer to change my data types in the database? Another question (more a curiosity). I noticed that some of the properties in the generated classes are declared with a ? after the datatype. I'm not familiar with this declaration construct... what gives? There are some declared as an int (non key fields) and others that are declared as int? (key fields). Does this have something to do with how they're treated at initialization? Any help is appreciated! --BUMP--

  • Underlying Concept Behind Keyboard Mappings

    - by ajay
    I am frustrated with key mapping issues. On my Linux box, if I type Home/End in Vim, then the cursor actually moves to the beginning/end of the line. On my Mac when I am on TextEdit, if I do Fn + Left or Fn + Right, it takes me to beginning/end of the line. But if I am on Vim on my Mac terminal, then the same key combinations don't work. Why? I see online all the different cryptic settings that I have to paste in .vimrc to make this work, but I can't find any explanation for those cryptic map, imap settings. What is the underlying issue here, and how can I fix it? Thanks!

  • Reasons to store users' data in LDAP instead of RDBMS

    - by Ancymon
    It is often said that using LDAP is a good way to store data about users. That's beacause users' "directory" is hierarchical and it changes rarely. But in my opinion that doesn't exclude using RDBMS. What might be reasons to use LDAP? I guess that storing multi-valued fields or adding custom fields in LDAP might be easier but it can be done in database too (unless you have many records)

  • Change the value of a dropdown if it is equal to something

    - by Jake Neal
    Sorry if this question has already been asked and answered, but I couldn't find anything specifically for my needs. I have a form that has placeholders and javascript to make sure the form isn't submitted with the placeholders still there. There is a dropdown box that has the value of 'Best time to call'. What I want to do is if this value is passed as the default, I want it to change to something like "n/a" or a blank value. I have achieved this with the comments box using the following javascript, but it doesn't seem to work the same for the dropdown: var comments=document.getElementById('comments').value; if (comments=="Comments") { document.getElementById('comments').value=""; } This isn't a required field so I can't have an alert come up, so I just need to value to be changed if submitted as 'Best time to call'. Hope I have explained everything correctly

  • Store password temporarily in memory

    - by Nils
    Hello, I'm looking for a way in an Android application to store a password within the memory as long as the application is running (cf. different activities). I was first thinking about the SharedPreferences, but then it's saved in the flash memory, which isn't that good for a password, I guess. I'm unsure, what's the best way. What would you recommend me?

  • Object pointer value as key into dictionary

    - by Ranking Stackingblocks
    I want to use the object's reference value as a key into a dictionary, as opposed to a copy of value of the object. So, I essentially want to store an object associated with a particular instance of another object in a dictionary and retrieve that value later. Is this possible? Is it completely against the idea of NSDictionary? I can tell that I am probably approaching this the wrong way because the dictionary wants me to implement NSCopying on the object itself, which doesn't really make sense in terms of what I'm doing. I can see that what I should really be doing is wrapping the pointer value, but that seems a little mad. Advice would be appreciated.

  • strlen returns incorrect value when called in gdb

    - by alesplin
    So I'm noticing some severely incorrect behavior from calls to standard library functions inside GDB. I have the following program to illustrate: #include <stdio.h> #include <stdlib.h> #include <string.h> int main(int argc, char *argv[]) { char *s1 = "test"; char *s2 = calloc(strlen("test")+1,sizeof(char)); snprintf(s2,strlen("test")+1,"test"); printf("string constant: %lu\n", strlen(s1)); printf("allocated string: %lu\n", strlen(s2)); free(s2); return 0; } When run from the command-line, this program outputs just what you'd expect: string constant: 4 allocated string: 4 However, in GDB, I get the following, incorrect output from calls to strlen(): (gdb) p strlen(s1) $1 = -938856896 (gdb) p strlen(s2) $2 = -938856896 I'm pretty sure this is a problem with glibc shipped with Ubuntu (I'm using 10.10), but this is a serious problem for those of us who spend lots of time in GDB. Is anyone else experiencing this kind of error? What's the best way to fix it? Build glibc from source? (I'm already running a version of GDB built from source)

  • C Question: How to store data inside the executable file

    - by michael
    Hello all, complete newbie here, I need to find a way to store 250 KB of plain text numbers inside my program's executable file. Usually, I would put the data in a separate file and let the program read it while it is running, but that's not an option here. Instead, the program and the data need to be in one executable file. I have absolutely no idea how to do it (except writing 250.000 #defines :-) and I'd appreciate any suggestions. Thank you very much!

  • Store NSArray In Core Data Sample Code?

    - by Stunner
    Ey guys, I have been searching for some sample code on how to store an NSArray in Core Data for awhile now, but haven't had any luck. Would anyone mind pointing me to some tutorial or example, or better yet write a simple sample as an answer to this question? I have read this but it doesn't show an example of how to go about implementing a transformable attribute that is an NSArray. Thanks in advance!
