  • PHP - How to display other values, when a query is limited by 3?

    - by Dodi300
    Hello. Can anyone tell me how to display the other values, when a query is limited my 3. In this question I asked how to order and limit values, but now I want to show the others in another query. How would I go about doing this? Here's the code I used before: $query = "SELECT gmd FROM account ORDER BY gmd DESC LIMIT 3"; $result = mysql_query($query); while($row = mysql_fetch_array($result, MYSQL_ASSOC)) { } Thanks!

  • In PHP can I check a boolean on a function call?

    - by Chris
    I have a function which checks the passed value and returns false or true, if false I want it to add something to an array. The code I've written is below. if(!check_input($_POST['username'])){ $errors[] = "Username"; } Right now it adds to my array anyway, regardless of what is entered in the form. Is the way I've written that the correct way to check if the return from check_input() is false? I've checked the function's logic by altering the returns to echoes and it's returning the correct value, I'm just not sure if I'm checking it wrong. I'd previously attempted to write it as $X=check_input etc, and then if(check_value == false) but that doesn't seem to give me the desired result either. Hmmm a quick pointer please!

  • jQuery slider to load content one at a time

    - by Barrett
    I have a slider that load all of my content at once. Into a div. Like so: external page.php $get_users = mysql_query("SELECT * FROM user WHERE id!='$user_id'"); while ($rows = mysql_fetch_assoc($get_users)) { $id = $rows['id']; $firstname = $rows['firstname']; $display_info .= ' <div class="f_outer" id="' . $id . '"> <div class="f_name likeu">' . $firstname . '</div> </div>'; } echo $display_info; I call this page from my find.php page using bxslider Here is my find.php page below. <script type="text/javascript"> $(function() { var slider = $("#slider1").bxSlider(); $("#slider-like").live('click', function() { slider.goToNextSlide(); return false; }); }); </script> <div id="slider-like>Yes</div> <div id="slider1"> <?PHP include ("external.php"); ?> </div> So what I get is all of my .f_outer div on the find.php page. I have hundreds of user and they will all be loaded at once. I would like to only load one slide at a time. So when I click #slider-like it load one of my dive from my external page.

  • How to pass a parameter in a Javascript confirm function?

    - by Miles M.
    I have something like that in my code: <?php foreach($clients as $client): ?> <tr class="tableContent"> <td onclick="location.href='<?php echo site_url('clients/edit/'.$client->id ) ?>'"><?php echo $client->id ?></td> <td><a class='Right btn btn-danger' onClick="ConfirmMessage('client', <?php $client->id ?>,'clients')"> <i class="icon-remove-sign icon-white"></i> </a></td> </tr> <?php endforeach ?> that's actually the view. So when the user click on the delete button (thr one with the btn-danger class) I'd like him to confirm his choice with a javascript confirmation box message. You can find that script in the header <script> function ConfirmMessage(type, id, types) { if (confirm("Are you sure you want to delete this ",type," ?")) { // Clic sur OK document.location.href='<?php echo site_url(); ?>',types,'/delete/',id; } } </script> So here is my question: I would like the $type to be replaced by a paramenter (like client, article, post .. ) that I'll pass to the function. And i would like to get the $client-id parameter as well. I'm bad in javascript and as you already have guess, It is obviously not working at all.

  • PHP - get MySQL query results as their native data type?

    - by redidas
    I've tried fetching MySQL query results using mysql_fetch_row() mysql_result() and numeric values are being returned as strings. Is there any way to fetch the data as its datatype stored in the table? The application will be querying many different queries so I will be unable to cast the values as the intended datatype on a 1 by 1 basis.

  • How to calculate Content-Length for a file download within Kohana PHP?

    - by moritzd
    I'm trying to send a file from within a Kohana model to the browser, but as soon as I add a Content-Length header, the file doesn't start downloading right away. Now the problem seems to be that Kohana is already outputting buffers. An ob_clean at the begin of the script doesn't help this though. Also adding ob_get_length() to the Content-Length isn't helping since this just returns 0. The getFileSize() function returns the right number: if I run the script outside of Kohana, it works. I read that exit() still calls all destructors and it might be that something is outputted by Kohana afterwards, but I can't find out what exactly. Hope someone can help me out here... This is the piece of code I'm using: public function download() { header("Expires: ".gmdate("D, d M Y H:i:s",time()+(3600*7))." GMT\n"); header("Content-Type: ".$this->getFileType()."\n"); header("Content-Transfer-Encoding: binary\n"); header("Last-Modified: " . gmdate("D, d M Y H:i:s",$this->getCreateTime()) . " GMT\n"); header("Content-Length: ".($this->getFileSize()+ob_get_length().";\n"); header('Content-Disposition: attachment; filename="'.basename($this->getFileName())."\"\n\n"); ob_end_flush(); readfile($this->getFilePath()); exit(); }

  • How do I turn a PDF email attachment to an image (jpg) in a PHP page?

    - by user351630
    Hi guys. Long time viewer, first time question asker. I'm trying to have my personal website parse through my mail box for attachments from a certain subscription list, and then be able to view the PDF attachments as images, preferably jpg. With the help of this: http://www.linuxscope.net/articles/mailAttachmentsPHP.html I'm currently using imap_base64() to decode the MIME data and create the PDF. However, I hate using PDF readers in general and I thought it would be a lot more streamlined if I could just view it as an image instead. I've heard for convert with ImageMagick, but would I need to actually write the PDF to a directory before using this, or can I convert somehow directly from the MIME data in the email? Thanks in advanced!

  • PHP: Collect all variables passed to a function as array?

    - by Industrial
    Hi everybody, I was thinking about the possibility of accessing all the variables that are passed into an function, and merge them into an array. (Without passing variables into an array from the beginning) Pseudo-code: // Call function newFunction('one', 'two', 'three' ) ;// All values are interpreted as a one rray in some way // Function layout newFunction( ) { // $functionvariables = array( All passed variables) foreach ($functionvariable as $k => $v) { // Do stuff } }

  • How do I generate an Array string from an array in memory (php).

    - by Itay Moav
    I need to create a big array in my code, I have the values in several tables (for easy management). I select it and now I have all the values in an array, in memory in the way I want. My problem, I need to write this array down, into the code. Is there a way to take an array which sits in the memory and translate it into a string "array('g'='h','b'='d'....)" which I can then echo and just copy-paste into my code?

  • PHP: How to know if a user is currently downloading a file?

    - by metrobalderas
    I'm developing a quick rapidshare-like site where the user can download files. First, I created a quick test setting headers and using readfile() but then I found in the comments section there's a way to limit the speed of the download, which is great, here's the code: $local_file = 'file.zip'; $download_file = 'name.zip'; // set the download rate limit (=> 20,5 kb/s) $download_rate = 20.5; if(file_exists($local_file) && is_file($local_file)) { header('Cache-control: private'); header('Content-Type: application/octet-stream'); header('Content-Length: '.filesize($local_file)); header('Content-Disposition: filename='.$download_file); flush(); $file = fopen($local_file, "r"); while(!feof($file)) { // send the current file part to the browser print fread($file, round($download_rate * 1024)); // flush the content to the browser flush(); // sleep one second sleep(1); } fclose($file);} else { die('Error: The file '.$local_file.' does not exist!'); } But now my question is, how to limit the number of downloads at the same time? How can I check there's still a connection with some user's IP? Thanks.
