  • PHP/Codeigniter processing a list with javascript

    - by user270797
    I have a list of items that the user can select. I want it to be more user friendly than standard checkboxes so I have seperate div's each with a unique id. When user clicks an item, I use javascript to display a tick on top of that item and change the style to show that it is highlighted. Im trying to work out how I can pass the list of id's when the form is submitted. Remember, if the user unticks an item, it should be removed from the list, I was thinking of using comma seperated values in a hidden text field but couldnt work out how to remove items from the start of the list if they were deselected

  • help with converting javascript function to php

    - by Haroldo
    My javascript isnt so great, but i found a brilliant looking function here I'm not sure what to do with this bit: var ranges = [], rstart, rend; full function: function getRanges(array) { var ranges = [], rstart, rend; for (var i = 0; i < array.length; i++) { rstart = array[i]; rend = rstart; while (array[i + 1] - array[i] == 1) { rend = array[i + 1]; // increment the index if the numbers sequential i++; } ranges.push(rstart == rend ? rstart+'' : rstart + '-' + rend); } return ranges; } getRanges([2,3,4,5,10,18,19,20]); // returns ["2-5", "10", "18-20"] getRanges([1,2,3,5,7,9,10,11,12,14 ]); // returns ["1-3", "5", "7", "9-12", "14"] getRanges([1,2,3,4,5,6,7,8,9,10]) // returns ["1-10"]

  • How to change file contents in PHP ?

    - by Misha Moroshko
    I save in a file some info about users (like number of times user passed the login page, last visited time, and so on). I want to read this info from the file, and update it (add 1 to the counter, and change the last visited time). My question is: can I do it without opening the file twice ? I open the first time to read the contents, and then open it again to overwrite the contents with the updated ones. Thanks !

  • PHP/codeigniter - use of exit()

    - by Patrick
    I have a few pages that require login, so all controllers that link to these pages start with $this->checkSession(); //...rest of the code CheckSession should verify the session is still live, otherwise display a message and stop the execution of the rest of the code in the controller: function checkSession() { if (!$this->session->userdata('is_logged_in')) { //the session has expired! $data['main'] = 'confirmation_message'; $data['title'] = "Session expired"; $this->load->vars($data); $this->load->view('template'); exit(); } } . I was expecting these instructions to happen in sequence, but I only get a blank page. How can I make sure exit() gets executed only after all views are loaded?

  • Sort multidimension array in php by more than two fields

    - by Ankita Agrawal
    I want to sort array by two fields. I mean to say I have an array like :- Array ( [0] => Array ( [name] => abc [url] => http://127.0.0.1/abc/img1.png [count] => 69 [img] => accessoire-sets_1.jpg ) [1] => Array ( [name] => abc2 [url] => http://127.0.0.1/abc/img12.png [count] => 73 [img] => ) [2] => Array ( [name] => abc45 [url] => http://127.0.0.1/abc/img122.png [count] => 15 [img] => tomahawk-kopen_1.png ) [3] => Array ( [name] => zyz [url] => http://127.0.0.1/abc/img22.png [count] => 168 [img] => ) [4] => Array ( [name] => lmn [url] => http://127.0.0.1/abc/img1222.png [count] => 10 [img] => ) [5] => Array ( [name] => qqq [url] => http://127.0.0.1/abc/img1222.png [count] => 70 [img] => ) [6] => Array ( [name] => dsa [url] => http://127.0.0.1/abc/img1112.png [count] => 43 [img] => ) [7] => Array ( [name] => wer [url] => http://127.0.0.1/abc/img172.png [count] => 228 [img] => ) [8] => Array ( [name] => hhh [url] => http://127.0.0.1/abc/img126.png [count] => 36 [img] => ) [9] => Array ( [name] => rrrt [url] => http://127.0.0.1/abc/img12.png [count] => 51 [img] => ) [10] => Array ( [name] => yyy [url] => http://127.0.0.1/abc/img12.png [count] => 22 [img] => ) [11] => Array ( [name] => cxz [url] => http://127.0.0.1/abc/img12.png [count] => 41 [img] => ) [12] => Array ( [name] => tre [url] => http://127.0.0.1/abc/img12.png [count] => 32 [img] => ) [13] => Array ( [name] => fds [url] => http://127.0.0.1/abc/img12.png [count] => 10 [img] => ) ) array WITHOUT images (field "img" )should always be placed underneath array WITH images. After this there will be sorted on the amount of products (field count) in the array. Means I have to show sort array first on the basis of img then count. I am using usort( $childLinkCats, 'sortempty' );` function sortempty( $a, $b ) { return empty( $a['img'] ); } it will show array with image value above the one who contains null value. and to sort through count Im using usort($childLinkCats, "_sortByCount"); function _sortByCount($a, $b) { return strnatcmp($a['count'], $b['count']); } It will short by count But I am facing problem that only 1 working is working at a time, but I have to use both, please help me.

  • SQL-How to retrieve the correct data using php

    - by Programatt
    I am new to SQL so please excuse my question if it is simple. I have a database with a few tables. 1 is a users table, the others are application tables that contain the users preferences for receiving notifications about that application based on the country they are interested in. What I want to do, is retrieve the e-mail address of all users that have an interest in that country. I am struggling to think about how to do this. I currently have the following query constructed, and the code to populate the values function check($string) { if (isset($_POST[$string])) { $print = implode(', ', $_POST[$string]); //Converts an array into a single string $imanageSQLArr = Array(); if (substr_count($print,'Benelux') > 0) { $imanageSQLArr[0] = "checked"; } else { $imanageSQLArr[0] = "off"; } if (substr_count($print, 'France') > 0) { $imanageSQLArr[1] = "checked"; } else { $imanageSQLArr[1] = "off"; } if (substr_count($print, 'Germany') > 0) { $imanageSQLArr[2] = "checked"; } else { $imanageSQLArr[2] = "off"; } if (substr_count($print, 'Italy') > 0) { $imanageSQLArr[3] = "checked"; } else { $imanageSQLArr[3] = "off"; } if (substr_count($print, 'Netherlands') > 0) { $imanageSQLArr[4] = "checked"; } else { $imanageSQLArr[4] = "off"; } if (substr_count($print, 'Portugal') > 0) { $imanageSQLArr[5] = "checked"; } else { $imanageSQLArr[5] = "off"; } if (substr_count($print, 'Spain') > 0) { $imanageSQLArr[6] = "checked"; } else { $imanageSQLArr[6] = "off"; } if (substr_count($print, 'Sweden') > 0) { $imanageSQLArr[7] = "checked"; } else { $imanageSQLArr[7] = "off"; } if (substr_count($print, 'Switzerland') > 0) { $imanageSQLArr[8] = "checked"; } else { $imanageSQLArr[8] = "off"; } if (substr_count($print, 'UK') > 0) { $imanageSQLArr[9] = "checked"; } else { $imanageSQLArr[9] = "off"; } and the query $tocheck = $db->prepare( "SELECT users.email FROM users,app WHERE users.id=app.userid AND BENELUX=:BENELUX AND FRANCE=:FRANCE AND GERMANY=:GERMANY AND ITALY=:ITALY AND NETHERLANDS=:NETHERLANDS AND PORTUGAL=:PORTUGAL AND SPAIN=:SPAIN AND SWEDEN=:SWEDEN AND SWITZERLAND=:SWITZERLAND AND UK=:UK"); $tocheck->execute($country); $row = $tocheck->fetchAll(); This does retrieve data, but only people who's preferences match EXACTLY what is put (so what they haven't selected is taken into account as much as what they have). Any help would be greatly appreciated.

  • 'Previous' Button in HTML/PHP

    - by vlad
    Hi there, I thought hours about that problem but I didn't come to any conclusion. My problem here is that I need a 'Previous' Button added to a form. The user should fill out a formular that is splitted up in 13 parts. Every part is an own formular having a 'Next' button for submitting everything to a database and redirecting to the next page. How do I integrate a 'Previous' button there? ... I don't if it might be usefull for you to know that I'm using cakePHP, and well I'm pretty new to it.

  • My IF statement is changing variables in PHP

    - by user1902509
    I am fairly new to the whole programming thing, so forgive me if this is a stupid question. It seems odd that I haven't run into it before. I am trying to make an order form for a cake. You fill out the form, submit it, and it will then display the order in a new window, where you then hit "submit," and upload it to the Database. I have a series of If Statements to check for errors in the form before submitting it. Here is a simplified version of the code. Writing means any writing you want on the cake, Name is your name, and cake is what type of cake you want (the default is "None"). try { $name = trim($params->name); $cake = trim($params->cake); $writing = trim($params->writing); if (strlen($name) < 3){ throw new Exception("Please enter Your name."); } if ($cake = "None") { throw new Exception("Please select a Cake" } if ($cake = "Caramel Apple Pie" or $cake = "Pumpkin Pie" or $cake = "Eggnog Pie" and strlen($writing) > 1) { throw new Exception("We are sorry, but you can't write on any of our specialty pies."); } } catch(Exception $x) { $error = $x->getmessage(); } So what is happening is that when I go and hit submit the first time, the correct cake type comes up, but when you submit it the second time, the error comes up saying that I have "None" selected. All the other values are there and remain the same. I think the problem is that the first "IF" statement (Where it says "If($cake = "None")) is automatically changing $cake to "None" because I have tried commenting just that statement out, and it will then change the cake to be "Caramel Apple Pie," which is in the top of the next IF statement. Anyone know why it is doing this? And how to fix it?

  • Inheriting database connection in PHP OOP

    - by vrode
    My abstract class Database is made for database interaction and any child of this class (UserDatabase, ActionDatabase, EventDatabase) inherits its database connection which is defined as static. `abstract class Database { static $connection = mysql_connect( ); } class UserDatabase extends Database { ... public function __construct( ) { $connection ? "connected" : "not connected"; $this-table = "users"; mysql_query( "FROM " . $this-table . " SELECT *" ); } } ` Does that mean, that my database connection is only set up and stored in memory once and passed on to subclasses as reference without being replicated for each instance? Is this how you would implement you OOP-correct database interface?

  • php regex to split invoice line item description

    - by user1053700
    I am attempting to split strings like the following: An item (Item A) which may contain 89798 numbers and letters @ $550.00 4 of Item B @ $420.00 476584 of Item C, with a larger quantity and different currency symbol @ £420.00 into: array( 0 => 1 1 => "some item which may contain 89798 numbers and letters" 2 => $550.00 ); does that make sense? I am looking for a regex pattern which will split the quantity, description, and price (including symbol). the strings will always be: qty x description @ price+symbol so i assume the regex would be something like: `(match a number and only a number) x (get description letters and numbers before the @ symbol) @ (match the currency symbol and price)` How should I approach this?

  • Read part of a file in PHP

    - by Johan
    I would like to read the last 1 megabyte of a MP3 file and calculate SHA1 checksum for just that part of the file. The reason that I would want this is that when I'm looking for duplicate MP3's, the header info (song title, album etc.) can differ even though it's the exakt same audio file, so I figured I would be better of to checksum a part of the file at the end instead of the whole one. Is there an efficient way of doing this?

  • Encryption in PHP leaves unwanted characters

    - by MichaelH
    I have made an encryption function which encrypts a simple value and stores it in the database. Here is the code to encrypt and decrypt: public function encrypt($string){ $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_ECB); $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND); $value = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $this->key256, $string, MCRYPT_MODE_ECB, $iv); $value = base64_encode($value); return $value; } public function decrypt($string){ $value = base64_decode($string); $value = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $this->key256, $value, MCRYPT_MODE_ECB); return $value; } When I encrypt a simple value such as 'Michael' and decrypt again, I get the value: Michael????????? Is there a reason I get all those question marks or a way to get rid of them?

  • In PHP + MySQL, How do I join many tables with conditions

    - by Moe
    Hi, I'm trying to get the users full activity throughout the website. I need to Join many tables throughout the database, with that condition that it is one user. What I currently have written is: SELECT * FROM comments AS c JOIN rphotos AS r ON c.userID = r.userID AND c.userID = '$defineUserID'; But What it is returning is everything about the user, but it repeats rows. For instance, for one user he has 6 photos and 5 comments So I expect the join to return 11 rows. Instead it returns 30 results like so: PhotoID = 1; CommentID = 1; PhotoID = 1; CommentID = 2; PhotoID = 1; CommentID = 3; and so on... What am i doing wrong?

  • PHP Header redirection problem within page called by cURL

    - by Das123
    I have a site that uses cURL to access some pages, stores the returned results in variables, and then uses these variables within its own page. The script works well except where the target cURL page has a header('Location: ...') command inside it. It seems to just ignore this header command. The cURL command is as follows... //Load result page into variable so portions can be allocated to correct variables $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); # URL to post to curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 ); # return into a variable curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields); $loaded_result = curl_exec( $ch ); # run! curl_close($ch); I've tried changing the CURLOPT_HEADER to 1 but it doesn't do anything. So how can I allow script redirection within the target urls using cURL to grab the results? By the way, the pages work fine if accessed other than via cURL but iFrames are not an option in this instance.
