• 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...

• How can I give a color to imagecolorallocate?

  - by Roman

  I have a PHP variable which contains information about color. For example $text_color = "ff90f3". Now I want to give this color to imagecolorallocate. The imagecolorallocate works like that: imagecolorallocate($im, 0xFF, 0xFF, 0xFF); So, I am trying to do the following: $r_bg = bin2hex("0x".substr($text_color,0,2)); $g_bg = bin2hex("0x".substr($text_color,2,2)); $b_bg = bin2hex("0x".substr($text_color,4,2)); $bg_col = imagecolorallocate($image, $r_bg, $g_bg, $b_bg); It does not work. Why? I try it also without bin2hex, it also did not work. Can anybody help me with that?

• Can I include a view in Kohana 3 that is not within `application/views`?

  - by alex

  I am building a staff area for a website, which is completely different to the main brochure style site. I have 2 Kohana systems setup. I realise they can both share the same system and modules folder. Now, with the second one, I want to make the main template view a view in a different folder. I tried this in my base controller $this->template = DOCROOT . '../~new2/application/views/template.php'; But Kohana is looking for it in its own views folder as evident by the error I received. I even put a var_dump(file_exists($this->template)); // true to be sure it was finding the correct file. Is there a way to add a template file that is not within the views folder, without hacking the core Kohana code (and if I'm lucky not extending and overloading the view class).

• An efficient way to store view counts for objects?

  - by Nick Brooks

  I maintain an application where users are able to store images, and then share them. The system is powered by MongoDB at the back end. Most of the image depiction pages are cached as flat HTML files, but I can run some code just before loading the file. I've decided to implement a view count for the system. I am wondering what is the best storage place for that. It should be like Memcached but it should save the viewcounts every hour or so, so even if our server has to be restarted we won't lose the view counts. What is the best solution for that (preferably with a PHP extension as a client)?

• My company is a Rackspace Cloud client (provided to us for free) and I'm trying to find some way to set up version control

  - by Nick S.

  As the title says, my (small) business is provided a free Rackspace Cloud client account. We receive a decent amount of traffic but I haven't been able to put together a business case to move to our own server yet. However, we are developing some complex apps and I'm frustrated with not having the ability to even ssh into the remote server. Ultimately, I'd like to set up some sort of version control (at this point, I'll take anything, git or otherwise). I have control over databases, can FTP, set up cron jobs, and perform a few other basic functions. I can't think of any way to set up git or something similar without ssh access. A thought went through my mind that maybe some sort of PHP version control exists that I might be able to set up, but I haven't had any luck finding it yet. Do you guys have any ideas, thoughts, or advice?

• Site works perfect in Mozilla but not in IE. Is my js file not compatible with IE

  - by Bonkers

  I'm working on a site written in PHP/MySQL. We have a form to reserve time on a calendar and it works great in Mozilla and stores the reservation to our database, but in IE you fill out the form and when you click the "Reserve" button to submit it and nothing happens. All I can think of is that my javascript is not working with IE. I have these lines in my .js file: resLenT = document.getElementById(resLenElem); resLenI = resLenT.selectedIndex; resLen = resLenI + 1; where resLenElem is a drop-down box. These are the only lines that I can think of at the moment that might be causing trouble in IE. Does this all sound like I'm on the right track or am I way off base?

• 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.

• Twitter URL encoding

  - by Rich

  Hi, We're about to launch a little twitter Christmas competition, and I've run into a little snag. To enter, people will need to post a tweet in the following format: @user blah, blah, blah #hashtag Currently, I have a form where they enter their answer (the blah, blah, blah) and a PHP script which encodes the entire statement and adds on the twitter url: http://www.twitter.com/home?status=%40user%20blah%2Cblah%2Cblah%20%23hashtag Then takes the user to twitter and puts the status in the update field. However, whilst the spaces (%20) are decoded fine the @ and # characters remain as %40 & %23 respectively, even when the tweet is posted. I cannot put the actual characters in the url as twitter mistakes this for a search. Is there any way to solve this? I'd like to do it without requiring username & password etc if possible. Any help will be greatly appreciated.

• Creating non-framework calsses in CakePHP

  - by Affian

  I'm making a tournament manager in CakePHP 1.3 and I have a tournament controller which is fine but I want to implement a interface that can be used to define how a tournament runs. the controller needs to load a concrete class that implements the TournamentStyle interface that defines how the tournament works. At the end of a round the TournamentStyle is used to calculate the scores and winners and generate the next round of matches. That gives me a .php file for the interface and other files for the various styles. My question is: where would I put these files and how would I load them into my tournament controller?

• Script Doesnt Run All the Way Through

  - by Chris

  I have a php script that should execute 2 for loops. Both take awhile to run. I have called ignore_user_abort(true) and set_time_limit(0). The interesting thing is, the first for loop completes, then the script dies without calling the next line of code. ignore_user_abort(true); set_time_limit(0); for($i=0; $i<10500; ++$i) { //do work } mail('[email protected]', 'First loop done', 'None'); for($j=0;$j<12500; ++$j) { //do work } mail('[email protected]', 'Second loop done', 'None'); The first loop will finish after about 20 minutes, but the mail function is never called, the script just ends. Any ideas why this might be happening other than a timeout (I have run other scripts for days on my current configuration)?

• Community based translating system

  - by mike

  Since we don't funds to hire translators for getting multiple languages translated we want the community to do the translation for us. Its a social network. I can't find any good open souce framework to auto do this. Thinking something like: User selects a language, system displays random sentences and user will translate it. Then other users can vote on how good it is. If it's 100 votes + with 95% yes then it becomes official. Site is in PHP. Any ideas?

• Picking encryption cipher for mcrypt

  - by Autolycus

  I have few questions about this code: <?php $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB); $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND); $key = "This is a very secret key"; $text = file_get_contents('path/to/your/file'); echo strlen($text) . "\n"; $crypttext = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, $text, MCRYPT_MODE_ECB, $iv); file_put_contents('path/to/your/file', $crypttext); ?> It encrypts the file just fine, however it adds additional nulls at the end, so if I encrypt: a test string is this one and here is a new line once decrypted becomes: a test string is this one and here is a new line 000000000000000 What's going on? Second, is MCRYPT_RIJNDAEL_256 compatible with AES-128? Finally, how would I let another party decrypt a file I've encrypted? They would need to know which encryption was used and I am not sure what to tell them.

• 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...

I want to be able to sort out my content in my websites by most viewed, most commented, most popular, best rating, etc...with a drop down list, check box, etc... but I don't know how "sort by" works?

• Want to 'sandbox' user form submitted HTML

  - by pmmenneg

  Hi all. I have a user form with a textarea that allows users to submit html formatted data. The html itself is limited by PHP strip_tags, but of course that does no completion checking etc. My basic problem is that should a user leave a tag unclosed, such as the tag, then all the content following that, including page content that follows that is 'outside' the user content display area, could now be malformed. Checking for proper tag completion is one solution I will look at, but ideally I'd like to firewall the user htmlified content away from the rest of the site somehow. Any suggestions on the best approach? Thanks!
