  • cakePHP paginate with post data without sessions, serialization or post to get

    - by openprojdevel
    I have created a small search and filter form method post in controller/index, which posts to it self the conditions and fields to paginate ( $this-paginate($conditions) ) However that is good for the first page, the subsequent pages the filer conditions are lost. pagination passArgs supports get variables well. Is there an un complex way to pass the post conditions to the other paginated pages? The method I have looked at is pass the $conditions in session , which isnt without complexity of assigning session and unset the session on submitting the form again (more refinements to the filter criteria by the user ) The other method is passing the $conditions as serialized string url_encode as an get parameter. Is there an good cake way to do this more like passArgs, sessions and url encode do not look like cake style. Thanks

  • How to optimize this algorithm?

    - by Bakhtiyor
    I have two sets of arrays like this for example. $Arr1['uid'][]='user 1'; $Arr1['weight'][]=1; $Arr1['uid'][]='user 2'; $Arr1['weight'][]=10; $Arr1['uid'][]='user 3'; $Arr1['weight'][]=5; $Arr2['uid'][]='user 1'; $Arr2['weight'][]=3; $Arr2['uid'][]='user 4'; $Arr2['weight'][]=20; $Arr2['uid'][]='user 5'; $Arr2['weight'][]=15; $Arr2['uid'][]='user 2'; $Arr2['weight'][]=2; The size of two arrays could be different of course. $Arr1 has coefficient of 0.7 and $Arr2 has coefficient of 0.3. I need to calculate following formula $result=$Arr1['weight'][$index]*$Arr1Coeff+$Arr2['weight'][$index]*$Arr2Coeff; where $Arr1['uid']=$Arr2['uid']. So when $Arr1['uid'] doesn't exists in $Arr2 then we need to omit $Arr2 and vice versa. And, here is an algorithm I am using now. foreach($Arr1['uid'] as $index=>$arr1_uid){ $pos=array_search($arr1_uid, $Arr2['uid']); if ($pos===false){ $result=$Arr1['weight'][$index]*$Arr1Coeff; echo "<br>$arr1_uid has not found and RES=".$result; }else{ $result=$Arr1['weight'][$index]*$Arr1Coeff+$Arr2['weight'][$pos]*$Arr2Coeff; echo "<br>$arr1_uid has found on $pos and RES=".$result; } } foreach($Arr2['uid'] as $index=>$arr2_uid){ if (!in_array($arr2_uid, $Arr1['uid'])){ $result=$Arr2['weight'][$index]*$Arr2Coeff; echo "<br>$arr2_uid has not found and RES=".$result; }else{ echo "<br>$arr2_uid has found somewhere"; } } The question is how can I optimize this algorithm? Can you offer other better solution for this problem? Thank you.

  • Using a database class in my user class

    - by Josh
    In my project I have a database class that I use to handle all the MySQL stuff. It connects to a database, runs queries, catches errors and closes the connection. Now I need to create a members area on my site, and I was going to build a users class that would handle registration, logging in, password/username changes/resets and logging out. In this users class I need to use MySQL for obvious reasons... which is what my database class was made for. But I'm confused as to how I would use my database class in my users class. Would I want to create a new database object for my user class and then have it close whenever a method in that class is finished? Or do I somehow make a 'global' database class that can be used throughout my entire script (if this is the case I need help with that, no idea what to do there.) Thanks for any feedback you can give me.

  • Cassandra or mysql 5

    - by saturngod
    Should I use cassandra in 100,000 users project ? In mysql 5 have full text search and partition table. I'm starting to make Question and answer system like stackoverflow with CodeIgniter. It's move from vbulletin to new system. In old vbulletin have around 100,000 users and total post is around 80,000. In next 3 or 4 year, users and posts will be more and more. So, Should I use cassandra instead of mysql 5 ? If I use cassandra, I need to change gridserver in mediatemple to DV server in mediatemple. Cassandra is not built in hosting system. So, I must use VPS or DV server. If I use mysql 5, hosting is not problem but how about speed and search. Btw, What database using in Stack Over ?

  • Preventing $.POST hijack

    - by Jamie
    I'm currently building a facebook application. Lets say I have a variable $uid that identifies the user so I can store this in my database along with their submitted data. I pass $uid and $data via json encoded values using $.post. However, this doesn't prevent someone changing $uid to save data as someone else. I have been thinking about how to overcome this, so far I haven't found a solution apart from: create database with $uid $secretkey on first page load. When $.post send $secretkey with the post and then retrieve the $uid from the database. Would this be the correct approach to use?

  • How to execute with /bin/false shell

    - by Amar
    I am trying to setup per-user fastcgi scripts that will run each on a different port and with a different user. Here is example of my script: #!/bin/bash BIND=127.0.0.1:9001 USER=user PHP_FCGI_CHILDREN=2 PHP_FCGI_MAX_REQUESTS=10000 etc... However, if I add user with /bin/false (which I want, since this is about to be something like shared hosting and I don't want users to have shell access), the script is run under 1001, 1002 'user' which, as my Google searches showed, might be a security hole. My question is: Is it possible to allow user(s) to execute shell scripts but disable them so they cannot log in via SSH?

  • Suggest me solution to track the change in test DB and replicate in Another DB

    - by Parth
    Suggest me solution to track the change in test DB and replicate in Another DB... My Client need a script or any solution, if he has two Database, One Test DB in which he tests his data on test portal and if he find it appropriate he can use those changes to be done in main DB to display on Live site.. Fior this he needs the solution to record or track all updation/deletion/insertion, so that he can do the same in main DB if found appropriate, ** NOTE: ** we hav only on server, no separate server, hence binary log replication doesnt seems to be working for my case...

  • Need to parse HTML document for links-- use a library like html5lib or something else?

    - by Luinithil
    I'm a very newbie webpage builder, currently working on creating a website that needs to change link colours according to the destination page. The links will be sorted into different classes (e.g. good, bad, neutral) by certain user input criteria-- e.g. links with content the user would find of interest is colored blue, stuff that the user (presumably) doesn't want to see is colored as normal text, etc. I reckon I need a way to parse the webpage for links to the content (stored in MySQL database), change the colors for all the links on the page (so I need to be able to change the link classes in the HTML as well) before outputting the adapted page to the user. I read that regex is not a good way to find those links-- so should I use a library, and if so, is html5lib good for what I'm doing?

  • optimize query: get al votes from user's item

    - by Toni Michel Caubet
    hi there! i did it my way because i'm very bad getting results from two tables... Basically, first i get all the id items that correspond to the user, and then i calculate the ratings of each item. But, there is two different types of object item, so i do this 2 times: show you: function votos_usuario($id){ $previa = "SELECT id FROM preguntas WHERE id_usuario = '$id'"; $r_previo = mysql_query($previa); $ids_p = '0, '; while($items_previos = mysql_fetch_array($r_previo)){ $ids_p .= $items_previos['id'].", "; //echo "ids pregunta usuario: ".$items_previos['id']."<br>"; } $ids = substr($ids_p,0,-2); //echo $ids; $consulta = "SELECT valor FROM votos_pregunta WHERE id_pregunta IN ( $ids )"; //echo $consulta; $resultado = mysql_query($consulta); $votos_preguntas = 0; while($voto = mysql_fetch_array($resultado)){ $votos_preguntas = $votos_preguntas + $voto['valor']; } $previa_r = "SELECT id FROM recetas WHERE id_usuario = '$id'"; $r_previo_r = mysql_query($previa_r); $ids_r = '0, '; while($items_previos_r = mysql_fetch_array($r_previo_r)){ $ids_r .= $items_previos_r['id'].", "; //echo "ids pregunta usuario: ".$items_previos['id']."<br>"; } $ids = substr($ids_r,0,-2); $consulta_b = "SELECT valor FROM votos_receta WHERE id_receta IN ( $ids )"; //echo $consulta; $resultado_b = mysql_query($consulta_b); $votos_recetas = 0; while($voto_r = mysql_fetch_array($resultado_b)){ $votos_recetas = $votos_recetas + $voto_r['valor']; } $total = $votos_preguntas + $votos_recetas; return $total; } As you can si this is two much.. O(n^2) Feel like thinking? thanks!

  • Complex SQL query... names of returned variables

    - by Andrew P.
    Excuse me for what I'm sure is an elementary question for most of you, but I have an issue with table columns from separate tables having the same name as one another, and trying to select from both tables in the same query. Okay, so this is my code: $q_value = $mdb2->quote($_POST['query']); $field = $_POST['field']; $sql = "SELECT m.*, l.name FROM memberlist m, mail_lists l WHERE m.$field=$q_value AND l.id = m.list ORDER BY m.id"; $l_list = $mdb2->queryAll($sql, '', 'MDB2_FETCHMODE_ASSOC'); The table memberlist has the following columns: id, email, list, sex, name and the table mail_lists has the following columns: id, name After running the query, I later loop through the results with a foreach like so: foreach ($l_list as $l){ //blahblah } The problem is that the column 'name' in mail_lists refers to the names of the list, while the column 'name' in memberlist refers to the name of the member. When I later access $l-name (within the foreach), will I get m.name, or l.name? Furthermore, how do I get access to the other? Or will I just have to do two separate queries?

  • OpenID Authentication 2.0 in Joomla 1.0.x

    - by Michael Pliskin
    Is there any easy way to bring OpenID authentication into a Joomla 1.0.x website? I am particularly interested in Google authentication (so I'll want OAuth &/or OpenID Attribute Exchange as well later), but for now just authentication will work. I know Joomla 1.5.x supports OpenID natively but I have to stick with 1.0.x for now. Any ideas? There are some traces of com_openid component on the net but I cannot find anything to look at.. EDIT I managed to find a J-OpenID component, gonna give it a try.

  • How do I prevent duplicate entrys to mySQL?

    - by ggfan
    On my site, I have a form that users fill out to become a member. They fill out name, bday, email, etc. Then when they click submit, the data gets into mySQL. But sometimes when a user clicks submit many times or refreshes the page, the data gets inputted to the database more than once. How can I prevent this? Is there a code I can use to only let one set of data get into the database? This is also a problem in my comment section. I allow uses to put comments on people's profiles. But when they abuse the refresh button or submit button, I get like 10 of the same comments. Thanks.
