• How to insert the recently inserteddata of a table to others DB's Table? See description...

  - by Parth

  I am using MySQL DB and I have created a PHP script for the following, now i need the idea for the below asked question.... please help... I have a table called audit trail whose structure is: id, trackid, table, operation, newvalue, oldvalue, field, changedone I have created triggers for insert/update/delete for every table of same DB, now whenever there is change in ny DB the triggers get activated and updates the Audit trail table accordingly.. I am tracking these changes so that i can use these changes to be done on production DB which is of same structure as of this test DB. Also when the admin finds that he does not need the changes recently he did for production DB then he can rollback it using the Old Data it stored in Ausittrail table of test db. Now here in audit trail table structure, there will be an insert for every single field change like-wise if a table has 4 fields then the change in that tavle will insert 4 rows in audit trail.. Coming to the question now, How can i find the latest change done from the Audit table so that I can insert these changes in Production DB.

• How to hide URL from users when submitting this form?

  - by Camran

  I have a form with many many fields... When submitting these fields, I use the POST method which hides the actual variables passed along to the PHP page. However, I can't get rid of the complete link. Changing from GET to POST did make all the form fields invisible in the URL, but this part is still visible: mydomain.com/bin/query# I want it to be invisible, or say: mydomain.com/search I have mod_rewrite enabled so there is a possibility to do this with mod_rewrite I think, but I am new to mod_rewrite so I need your help... How should I hide this URL? If you need more input let me know...

• client-side vs server-side

  - by amalafrida

  In general, should one design in order to place processing load on client-side? More specifically, a search engine to locate subscriber information requires a fair amount of parsing (multiple phone numbers to sort and format, hour of day, timezone, comparisons for possible substitutions of user information, etc.). Again, in general, is it preferred that one have client-side do the work? It seems to me 'yes' in a situation in which one will have many thousands of hits per minute. Use php for quick database queries ... process retrieved data client-side. yes ... no?

• AS or not to AS, queries

  - by zeMinimalist

  I'm fairly new to PHP/MySql and using queries in general. I was just wondering if there's any benefit to using "AS" in a query other than trying to make it look cleaner? Does it speed up the query at all? I probably could have figured this out by a google search but I wanted to ask my first question and see how this works. I WILL select an answer (unlike some people...) with: SELECT news.id as id news.name as name FROM news without: SELECT news.id news.name FROM news A more complex example from a many-to-many relationship tutorial I found: SELECT c.name, cf.title FROM celebrities AS c JOIN ( SELECT icf.c_id, icf.f_id, f.title FROM int_cf AS icf JOIN films AS f ON icf.f_id = f.f_id ) AS cf ON c.c_id = cf.c_id ORDER BY c.c_id ASC

• Form POST or sessions?

  - by eddienotizzard

  If you have an item where you allow users to add comments, how can you pass which item the user is replying too? I've though of using a hidden field in a form, however this can be easily changed using plugins such as firebug: <form method="post" action="blah"> <input type="hidden" name="item_id" value="<?php echo $item_id; ?>"> <!-- other form data here --> <input type="submit" name="submit"> </form> Or just simply using a session: $_SESSION['item_id'] = $item_id Is there a safe way to send the item data in a form?

  Something that bugs me for a long time: I want to convert this Array: // $article['Tags'] array(3) { [0] => array(2) { ["id"] => string(4) "1" ["tag"] => string(5) "tag1" }, [1] => array(2) { ["id"] => string(4) "2" ["tag"] => string(5) "tag2" }, [2] => array(2) { ["id"] => string(4) "3" ["tag"] => string(5) "tag3" }, } To this form: // $extractedTags[] array(3) { [0] => string(4) "tag1", [1] => string(4) "tag2", [2] => string(4) "tag3", } currently i am using this code: $extractedTags = array(); foreach ($article['Tags'] as $tags) { $extractedTags[] = $tags['tag']; } Is there any more elegant way of doing this, maybe a php built-in function?

• How do I display/compare a dynamic value of a mysql row in a if statement?

  - by Ralph The Mouf

  I have a checkboxes on my site that when unchecked, update their row in in the db as unchecked, and if checked,update their row in the db as checked. I am creating an ifstatement that will commence with its command if checked, and not if unchecked. I have echoed the variable and it is holding the proper value (checked or unchecked) but not sure if I am syntactically correct on displaying the state of the row in the db. This is what I am trying and will not work. I am new at php still and thank you very much for any help. if($auth->check_prof == 'checked'){// do the stuff in here}

  - by spyhunterx

  I'm planning on developing my own web 2.0 application from scratch, using Yii Framework, JQuery, and HTML5 Boilerplate or Boots Strap. But I have huge dilemma.

• Is there a limitation to the length of the query in mysql?

  - by Bakhtiyor

  I am asking this question because I need to know this limitation as I am generating SELECT query in my PHP script and the part of WHERE in this query is generated inside the loop. Precisely it looks like this $query="SELECT field_names FROM table_name WHERE "; $condition="metadata like \"%$uol_metadata_arr[0]%\" "; for($i=1; $i<count($uol_metadata_arr); $i++){ $condition.=" OR metadata like \"%$uol_metadata_arr[$i]%\" "; } $query.=$condition; $result=mysql_query($query); So, that's why I need to know how long my $query string can be, because the array *$uol_metadata_arr* could contain many items.

• How do I escape a new line character in a .ini file so that Zend_Config_Ini reads it literally?

  - by Nick

  I am trying to store a multiple line e-mail in an ini file using PHP/Zend Framework. My string has new lines characters in it, and when I use Zend_Config_Ini to parse the ini file, the new line characters come back escaped, so they are printed out on screen, instead of a line feed. Example: // ini file message = Hi {0},\n\nThis is a test message.\nGoodbye! is parsed by Zend_Config_Ini as: Hi {0},\\n\\nThis is a test message.\\nGoodbye! which then is printed out in the email as: Hi John,\n\nThis is a test message.\nGoodbye! Instead I want the e-mail to look like this: Hi John, This is a test message. Goodbye! Does anybody know how to achieve this? Thanks!

• Mongo: Finding from multiple queries

  - by waxical

  New to Mongo here. I'm using the PHP lib and trying to work out how I can find in a collection from multiple queries. I could do this by repeating the query with a different query, but I wondered if it can be done in one. I.e. $idsToLookFor = array(2124,4241,5553); $query = $db->thisCollection->find(array('id' => $idsToLookFor)); That's what I'd like to do. However it doesn't work. What I'm trying to do is find a set of results for all the id's at one time. Possible or just do a findOne on each with a foreach/for?

• Offer access to a private page without login

  - by dccarmo

  So I've been struggling with a nice and easy way to allow users to access a private page without asking them to fill out a login/password form. What I'm thinking about using right now is for each private page I generate a uniqueid (using php uniqid function) and then send the URI to the user. He would access his private page as "www.mywebsite.com/private_page/13ffa2c4a". I think it's relatively safe and user friendly, without asking too much of information. I thought maybe when the user access this page it would ask for it's e-mail just to be sure, but the best would be nothing at all. Is this really safe? I mean not internet banking safe, but enough for a simple access? Do you think there's a better solution? Thanks. :)

• passing array fields to jquery ajax

  - by Rob Brandt

  I have a form I am submitting via jquery ajax. Early in the form, I have this field: <select name="inquirymodule[]" id="inquirymodule"> The user can add as many as they like, and all the selects go into the inquirymodule[] array. The jQuery looks like this: jQuery.ajax({ type: 'POST', url: 'ajax.php', dataType: 'json', data: { inquirymodule: jQuery("select[name='inquirymodule[]']").serialize(), }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert('error'); } }); That works fine. Trying to do the same thing with a date, like this: <input class="formInput" type="text" id="startBreak0" name='startbreak[]' /> adding startbreak: jQuery("select[name='startbreak[]']").serialize() to the ajax call. It doesn't work, I cannot see why. Suggestions?

• MySql database design for a quiz

  - by Mark

  I'm making an online quiz with php and mysql and need a bit of help deciding how to design the database for optimal insert of questions/answers and to select questions for the quiz. The table will hold 80 questions each with 4 possible options plus the correct answer. When retrieving the questions and options from the database I will randomly select 25 questions and their options. Is it better to make a single column for all questions, options, and correct answers? For example: ID | Q | OPT1 | OPT2 | OPT3 | OPT4 | ANS Or would it be better to make a column for each individual question, option, and correct answer? For example: Q1 | Q1_OPT1 | Q1_OPT2 | Q1_OPT3 | Q1_OPT5 | Q1_ANS | Q2 | Q2_OPT1 | Q2_OPT2...

• Can I load lots of data only once and use it on each request?

  - by eikes

  Is there a way to load a big data object into the memory, which usually has to be loaded at each request, only once? In Java you can instantiate an object in a servlet when this servlet is loaded, but once it's there you can use it in any request. Example is below. Can this be done in PHP? public class SampleServlet extends HttpServlet { private static HugeGraphObject hgo; public void init() { hgo = HugeGraphObjectFactory.get(); } protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String param = request.getParameter("q"); response.getWriter().write(hgo.getSomeThing(param)); } }

• mysql result for pagination

  - by Reteras Remus

  The query is: SELECT * FROM `news` ORDER BY `id` LIMIT ($curr_page * 5), ( ($curr_page * 5) + 5 ) Where $curr_page is a php variable which is getting a value from $_GET['page'] I want to make a pagination (5 news on each page), but I don't know why the mysql is returning me extra values. On the first page the result ok: $curr_page = 0 The query would be: SELECT * FROM `news` ORDER BY `id` LIMIT 0, 5 But on the second page, the result from the query is adding extra news, 10 instead of 5. The query on the second page: SELECT * FROM `news` ORDER BY `id` LIMIT 5, 10 Whats wrong? Why the result has 10 values instead of 5? Thank you!

• How to automatically reflect the new Updates (on Database) to User Pages

  - by user296436

  I am trying to create a new Notice Alert using PHP and Javascript. Suppose that a 100 users are currently logged into to the Online Notice Board Application and any One user posts a new notice. I want an immediate alert signal on all the users screen. I know, that the simplest way of doing it is to constantly Ping the server but I don't want to do it as it will slow down the server. Moreover, I am on a shared host. So I don't have access to any Socket Port. That means, I cannot establish any direct Socket Communication Channel from the Server to the User Machine. Can any one suggest me some other solution to this kind of problems???

Here's the controller code excerpt: $data['query'] = $this->db->query('SELECT role_id, role_privilege FROM role'); $this->load->view('welcome_message', $data); And a view code excerpt: <?php echo count($query->result_array())."<br/>"; foreach ($query->result() as $row){ echo $row->role_id . '<br/>'; echo $row->role_privilege . '<br/>'; } echo 'Total result '.$query->num_rows(); ?> And what I get is next: 0 Total result Running query from a command line gives a 2 rowed output. Can someone point out what i'm missing?
