  • Inserting only unique values into an array

    - by karl
    I have a set of values that I'm pushing into an array in the order they occur $valsArray = array(); //I process each value from a file (code removed for simplicity) //and then add into the array $valsArray[] = $val; How do I turn this into an associative array instead where the value gets inserted (as $key of associative array) only if it doesn't exist. If it does exist increment its count ($value of associative array) by 1. I'm trying to find a more efficient way of handling those values compared to what I'm doing now.

    - by sergiobuj
    Hi, i have this piece of code that is giving me trouble. I know all the threads are reading the same struct. But i have no idea how to fix this. #include <pthread.h> #include <stdio.h> #include <stdlib.h> typedef struct { int a,b; } s_param; void * threadfunc(void *parm) { s_param *param2 = parm; printf("ID:%d and v:%d\n",param2->a,param2->b); pthread_exit(NULL); } int main(int argc, char **argv) { pthread_t thread[3]; int rc=0,i; void * status; for(i=0; i<3 ; ++i){ s_param param; param.b=10; param.a=i; rc = pthread_create(&thread[i], NULL, threadfunc, &param ); // !!!! if(rc){ exit(1); } } for(i=0; i<3 ; ++i){ pthread_join(thread[i],&status); } return 0; } output: ID:2 and v:10 ID:2 and v:10 ID:2 and v:10 and what i need: ID:0 and v:10 ID:1 and v:10 ID:2 and v:10 Thank you.

  • Symfony custom route works with frontend_dev.php but not with index.php

    - by dazhall
    Am I missing something or should my custom route work with the index.php (or nothing) instead of frontend_dev.php? I'm getting a 500 error when I go to the model, and a 404 for the show page. My route is: project_show: url: /project/:slug class: sfDoctrineRoute options: { model: Project, type: object } param: { module: project, action: show } Any help would be much appreciated! Thanks! Darren.

  • Using javascript to limit survey choices to three unique values

    - by leanne
    I'm required to use a limited survey application, and have to adapt the provided code to meet more advanced functionality. I need to create a weighted ranking question, so users can select their top three choices and the data will go into the survey application and be accessible in the survey reports. The application only supports 2 types of questions (text fill & multiple choice) but I can alter the code, as long as it still sends the form data back to the survey application. The code is set up so it will show a drop-down menu of 0-3 for each option. Now I want to limit the user's choices so they can only select one "1" "2" or "3", three choices total. Ideally, if the user already had "2" selected for one option and they tried to select it for another option, it would set the first "2" as "0" or blank. Is this possible to do with javascript? If so, does anyone know of a site that might show code like this, or provide similar enough examples that I could adapt it? Current code here: <html> <head><title>Survey</title></head> <!-- Changes - remove br to put dropdown next to text for each item. Switch text & dropdown order for each item. - add comments to separate each question - removed blue title font - add instructions Goals - limit choices to one 1 one 2 and one 3, three choices total. --> <link href="---" rel="stylesheet" type="text/css"> <body bgcolor="#3c76a3"> <!-- TRANSITIONAL DIALOG BOX --> <table border="0" align="center" cellpadding="0" cellspacing="0" style="background-attachment: scroll; background-color: #3c76a3; background-repeat: no-repeat; background-position: left top;" bgcolor="#3c76a3" topmargin="0" marginwidth="0" marginheight="0" width="100%" height="100%"> <tr> <td> <table border="0" align="center" cellpadding="0" cellspacing="0" id="survey"> <tr> <td><p>&nbsp;</p> <!-- HEADER END --> <!-- FORM START TAG --><form name="survey" action="---" method="POST"> <FONT face="Verdana, Arial, Helvetica, sans-serif"> <b>survey</b><hr> <!-- 1 --> <input type=hidden name="Buy R.J. a DeLorean_multiple_answers" value="one"> <font size=2><select name="Buy R.J. a DeLorean" SIZE=1> <option value=""> <option value="0">0 <option value="1">1 <option value="2">2 <option value="3">3 </select></font> <input type="hidden" name="Buy R.J. a DeLorean_help" value=""> <b><font size=2>Buy R.J. a DeLorean</font></b> <hr size=1> <!-- 2 --> <input type=hidden name="Fill Lisa's office with marshmallows._multiple_answers" value="one"> <font size=2><select name="Fill Lisa's office with marshmallows."

  • index 'enabled' fields good idea?

    - by sibidiba
    Content of a website is stored in a MySQL database. 99% of the content will be enabled, but some (users, posts etc.) will be disabled. Most of the queries end as WHERE (...) AND enabled Is it a good idea to create an index on the field 'enabled'?

  • Algorithm - combine multiple lists, resulting in unique list and retaining order

    - by hitch
    I want to combine multiple lists of items into a single list, retaining the overall order requirements. i.e.: 1: A C E 2: D E 3: B A D result: B A C D E above, starting with list 1, we have ACE, we then know that D must come before E, and from list 3, we know that B must come before A, and D must come after B and A. If there are conflicting orderings, the first ordering should be used. i.e. 1: A C E 2: B D E 3: F D result: A C B D E F 3 conflicts with 2, therefore requirements for 2 will be used. If ordering requirements mean an item must come before or after another, it doesn't matter if it comes immediately before or after, or at the start or end of the list, as long as overall ordering is maintained. This is being developed using VB.Net, so a LINQy solution (or any .Net solution) would be nice - otherwise pointers for an approach would be good.

  • Check for a unique value within a count, but get all results

    - by pedalpete
    I'm trying to create a single query which, similar to stack overflow, will give me the number of votes, but also make sure that the currently viewing user can't upvote again if they've already upvoted. my query currently looks like SELECT cid, text, COUNT(votes.parentid) FROM comments LEFT JOIN votes ON comments.cid=votes.parentid AND votes.type=3 WHERE comments.type=0 AND comments.parentid='$commentParentid' GROUP BY comments.cid But I'm completely stumpted on how to add the check to see if the userid is in the votes table. The other option is to add a seperate query where SELECT COUNT(*) FROM votes WHERE userid='$userid' AND parentid='$commentParentid' AND type=3 I'm just realizing I'm so lost with this that I don't even really know what tags to provide.

  • How to select only the first rows for each unique value of a column

    - by nuit9
    Let's say I have a table of customer addresses: CName | AddressLine ------------------------------- John Smith | 123 Nowheresville Jane Doe | 456 Evergreen Terrace John Smith | 999 Somewhereelse Joe Bloggs | 1 Second Ave In the table, one customer like John Smith can have multiple addresses. I need the select query for this table to return only first row found where there are duplicates in 'CName'. For this table it should return all rows except the 3rd (or 1st - any of those two addresses are okay but only one can be returned). Is there a keyword I can add to the SELECT query to filter based on whether the server has already seen the column value before?

  • Show users a list of unique items on Java Google App Engine

    - by James
    I've been going round in circles with what must be a very simple challenge but I want to do it the most efficient way from the start. So, I've watched Brett Slatkin's Google IO videos (2008 & 2009) about building scalable apps including http://www.youtube.com/watch?v=AgaL6NGpkB8 and read the docs but as a n00b, I'm still not sure. I'm trying to build an app on GAEJ similar to the original 'hotornot' where a user is presented with an item which they rate. Once they rate it, they are presented with another one which they haven't seen before. My question is this; is it most efficient to do a query up front to grab x items (say 100) and put them in a list (stored in memcache?) or is it better to simply make a query for a new item after each rating. To keep track of the items a user has seen, I'm planning to keep those items' keys in a list property of the user's entity. Does that sound sensible? I've really got myself confused about this so any help would be much appreciated.
