  • Trigger file download on a page with content

    - by jeffreyveon
    I have seen many websites triggering a file save-as dialog on a page with existing HTML content. How do they do this? I know about setting the right headers such as Content-disposition etc. but when I do that, the content of the page does not load, and immediately the file download is triggered...

  • Reverse wildcard search in codeigniter

    - by Andy Platt
    I am implementing a snippet-based content management system into my current project. Snippets can be associated with a page either by exact match of the full url falling back to a wildcard match on a partial url or finally a default snippet. To implement this I have a created table of page associations with a wildcard flag, the system first checks the current url against the non-wildcard associations and if it doesn't find a match it checks against the partial url's where the wildcard flag is set. In order to achieve this I am getting all the partial url's from the database and putting them into an array then walking the array to check for a match against the current url: protected function _check_wildcard($url = NULL) { if($url) { $q = $this->db->where('wildcard' ,'Y') ->from('content') ->get(); $wildcards = $q->result_array(); foreach($wildcards AS $wildcard) { if(strpos($url,$wildcard['url']) > 0) { return $wildcard['snipppet_id']; } } } else { return NULL; } } Can anyone suggest a better way to do this - preferably one that doesn't involve having to constantly download the full list of all the wildcards each time I load a page as I am afraid that this will have a negative effect on the scalability of the system down the line?

  • Some pro regular expressions help needed here

    - by Camran
    I need a special regular expression, have no experience in them whatsoever so I am turning to you guys on this one: I need to validate a classifieds title field so it doesn't have any special characters in it, almost. Only letters and numbers should be allowed, and also the swedish three letters å, ä, ö, and also not case sensitive. Besides the above, these should also be allowed: The "&" sign. Parenthesis sign "()" Mathematical signs "-", "+", "%", "/", "*" Dollar and Euro signs Accent sign or whatever it's called, for example in "coupé" the apostrophe above the "e". Double quote and singel quote signs. The comma "," and point "." signs Thanks

  • Zend Framework: How to handle exceptions in Ajax requests?

    - by understack
    Normally when an exception is thrown, Error controller takes command and displays error page with regular common header and footer. This behavior is not wanted in Ajax request. Because in case of error, whole html page is sent over. And in cases where I'm directly loading the content of http response in a div, this is even more unwanted. Instead in case of Ajax request, I just want to receive 'the actual error' thrown by exception. How can I do this? I think, one dirty way could be: set a var in ajax request and process accordingly. Not a good solution.

  • detect a string contained by another discontinuously

    - by SpawnCxy
    Recently I'm working on bad content(such as advertise post) filter of a BBS.And I write a function to detect a string is in another string not continuously.Code as below: $str = 'helloguys'; $substr1 = 'hlu'; $substr2 = 'elf'; function detect($a,$b) //function that detect a in b { $c = ''; for($i=0;$i<=strlen($a);$i++) { for($j=0;$j<=strlen($b);$j++) { if($a[$i] == $b[$j]) { $b=substr($b,$j+1); $c .=$a[$i]; break; } } } if($c == $a) return true; else return false; } var_dump(detect($substr1,$str)); //true var_dump(detect($substr2,$str)); //false Since the filter works before the users do their posts so I think the efficiency here is important.And I wonder if there's any better solution? Thanks!

  • select field information with min time value

    - by Scarface
    Hey guys quick question, I thought I was doing the right thing but I keep getting the wrong result. I am trying to simply find the id of the entry with the min time, but I am not getting that entry. $qryuserscount1="SELECT id,min(entry_time) FROM scrusersonline WHERE topic_id='$topic_id'"; $userscount1=mysql_query($qryuserscount1); while ($row2 = mysql_fetch_assoc($userscount1)) { echo $onlineuser= $row2['id']; } That is my query, and it does not work. This however does work which does not make sense to me SELECT id FROM scrusersonline WHERE topic_id='$topic_id' ORDER by entry_time LIMIT 1, can anyone quickly point out what I am doing wrong?

  • Submit multiple forms as one

    - by Stephen Sarcsam Kamenar
    I have two forms on the page. To the user it looks like 1 form, and I actually wish it was one form. But the way I'm trying to reuse code and include things, I can't avoid two forms in the source code... trying to act as one. I don't want to do ajax submit, I want a normal post submit, my form handler has redirects in it. How can I submit both of these, and get values that make sense on the server side. something like $_POST['form1]['whatever'] $_POST['form2]['thing'] Maybe take all the inputs from form 2, rename all of them with a prefix, and append them to form 1? I can't find a non-messy way of doing this. I don't think I need code, just a plan. Least messy idea wins.

  • How come this relative positioned div is displayed differently in IE?

    - by Camran
    What is with these microsoft browsers? Does microsoft ever do a good job at anything... Anyways, I have a relative positioned div inside another div. The inside-div is positioned with percentage (left: 0%; top:13%). My problem is that in all IE versions the div is displayed some pixels further down than where it is displayed in Chrome, or FF... Anybody recognize this? <div class="nav_container" id="nav_container"> <div id="nav_container2" style="position: relative; left: 0%; top: 13%;"></div> </div> Also, I am just about to browser adjust my website so some article about most common problems with IE is appreciated. Thanks UPDATE: Here is the style for the primary div. .nav_container { background-image: url(../Graphics/menu_lvl1.gif); height: 101px; width: 720px; }

  • Location of DB models in Zend Framework - want them centralized

    - by jeffkolez
    Maybe I've been staring at the problem too long and it's much simpler than I think, but I'm stuck right now. I have three websites that are going to share database models. I've structured my applications so that I have an application directory for each site and a public directory for each site. The DB models live in a directory in the library along with Zend Framework and my third party libraries. I use the Autoloader class and when I try to instantiate one of my DB classes, it fails. The library directory is in my include path, but for whatever reason it refuses to instantiate my classes. It will work if I have my models in my application directory, but that's not the point. They're supposed to be shared classes in a Library. $model = new Model_Login(); $model->hello_world(); This fails when its in the library. The class is just a test: class Model_Login { public function hello_world() { echo "hello world"; } } Everything works until I try to instantiate one of my models. I've even tried renaming the class to something else (Db_Login), but that doesn't work either. Any ideas? Thanks in advance.

  • User's possibilities on site

    - by Lari13
    I want to build a system on the website, that allows users to do some things depend on their rating. For example I have rule for rating value X: 1 post in 3 days 10 comments in 1 day 20 votes in 2 days for rating value Y, rule may be following: 3 post in 1 day 50 comments in 1 day 30 votes in 1 day Each night I recalculate users' ratings, so I know what each user is able to do. Possibilities don't sum or reset on each rating's recalculation. One more important thing is that admin can fill concrete user's possibilities at any time. What is optimal database (MySQL) structure for desired? I can count what concrete user has done: SELECT COUNT(*) FROM posts WHERE UserID=XXX AND DateOfPost >= 'YYY' SELECT COUNT(*) FROM comments WHERE UserID=XXX AND CommentOfPost >= 'YYY' But how can I do admin filling possibilities in this case?

  • How to get the ID of the last insert.

    - by James Jeffery
    I have an application and around 20 accounts are created per minute (on average). I need to implement a new feature which requires the ID of the last insert. I am using PDO. The question is, lets say 5 users create accounts at exactly the same time. Will it return the ID from the database for that users profile that was just created, or will it return the last insert? If you get what I mean.

  • Check directory exists and if it doesnt choose an image

    - by Andy
    I have this code so far which perfectly but relies on there being a directory in place: $path = '/home/sites/therealbeercompany.co.uk/public_html/public/themes/trbc/images/backgrounds/'.$this->slug; $bgimagearray = array(); $iterator = new DirectoryIterator($path); foreach ($iterator as $fileinfo) { if ($fileinfo->isFile() && !preg_match('\.jpg$/', $fileinfo->getFilename())) { $bgimagearray[] = "'" . $fileinfo->getFilename() . "'"; } } I need to work in a bit at the top so that if the directory doesnt exist it defaults to the images sat in the root of the background directory... Any help would be appreciated.

  • How can I handle this kind of exceptions (in Doctrine)

    - by ppavlovic
    Can you tell me how can I handle this kind of exceptions: Fatal error: Uncaught exception 'Doctrine_Connection_Exception' with message 'PDO Connection Error: SQLSTATE[HY000] [2013] Lost connection to MySQL server at 'reading initial communication packet', system error: 110' in ... It happens when connection with MySQL is lost during query. I need to handle this exception so I can show 500 error page so the crawlers do not cache page, and to redirect user to appropriate "Try again" page. P.S. I have a lot's of code, so I can not go trough all code to put try/catch block. I need something simple and yet effective.
