  • PHP save a page then redirect to previous page(ajax)

    - by Shiro
    Dear all, I would like to ask for how to redirect to previous page (ajax paging). Example, Let's say currently I am in page 5, then I click on one record, after I edit it, I would like to go back to that page 5 not page 1. The problem is my paging is using ajax, http://domain/photo/#5 I try to use $_SERVER[http_referer], but I only get http://domain/photo , I not able to get # and the value. What is the best way to redirect back to the previous paging. My last choice is using $_SESSION. Hope I can get better answer here. Thx.

  • PHP Count the lenght of each value in a array/string (tags)

    - by 2by
    Users writing an article have the option to write some tags, tags are written like this: tag1, tag2, tag3 So tags are stored like: $tags = "tag1, tag2, tag3"; I want to make sure, every tag has a minimum of 3 characters, so i need to validate the tags. I have tried this: $tagsstring = explode(",", $tags); $tagslength = array_map('strlen', $tagsstring); if (min($tagslength) < 3) { echo "Error... Each tag has to be at least 3 characters."; } It seems to work, sometimes... But of you write: tag1, df It wont give an error. Any suggestions?

  • 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.

  • '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.

  • PHP Game weapon accuracy

    - by noko
    I'm trying to come up with a way for players to fire their weapons and only hit for a certain percentage. For example, one gun can only hit 70% of the time while another only hits 34% of the time. So far all I could come up with is weighted arrays. Attempt 1: private function weighted_random(&$weight) { $weights = array(($weight/100), (100-$weight)/100); $r = mt_rand(1,1000); $offset = 0; foreach($weights as $k => $w) { $offset += $w*1000; if($r <= $offset) return $k; } } Attempt 2: private function weapon_fired(&$weight) { $hit = array(); for($i = 0; $i < $weight; $i++) $hit[] = true; for($i = $weight; $i < 100; $i++) $hit[] = false; shuffle($hit); return $hit[mt_rand(0,100)]; } It doesn't seem that the players are hitting the correct percentages but I'm not really sure why. Any ideas or suggestions? Is anything glaringly wrong with these? Thanks

  • PHP / Windows - Opendir() fails opening subdirectories within symbolic linked directories

    - by John Himmelman
    Does anyone know a solution to this problem? I'm unable to open a subdirectory within a symboliclink'd directory. I've confirmed that the paths are correct (even copy & pasted the path into explorer, which parsed it fine). This is a strange, annoying, bug :|. Example: C:\folder\symbolic_link\dir1\dir2 - opening dir2 fails. C:\folder\symbolic_link\dir1 - works C:\folder\real_directory\dir1\dir2 - works C:\folder\real_directory\dir1 - works

  • php extending but with a new constructor...possible?

    - by Patrick
    I have a class: class test { function __construct() { print 'hello'; } function func_one() { print 'world'; } } what I would like to do is a have a class that sort of extends the test class. I say 'sort of', because the class needs to be able to run whatever function the test class is able to run, but NOT run the construct unless I ask it to. I do not want to override the construct. Anyone has any idea how to achieve this?

  • 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?

  • Referral System PHP

    - by Liam
    I have a membership based website and im planning on implementing a referral system. My website is credit based, the idea is that if User X refers User Y, then User X gets 100 bonus credits. Has anybody built a referral system before and if so what obstacles should I bear in mind? I've had a snoop round SO tonight but couldn't find any suitable answers. My theory is to give each user a random string which is generated and stored in the DB when they sign up, The user will then be presented with a URL incl. that string which when they pass to somebody (User Z), User Z is then sent to a page, the page then uses the GET method to gather the Random string and update the DB Row they currently occupy, does this sound feasible or could it easily be breached? Thanks

  • PHP sleep accuracy

    - by Abs
    Hello all, I use the following code to see how long a user is on a particular page. I use a hidden image with a src attribute to this script: $timer_seconds = 1; while(!connection_aborted()) { echo "\n"; flush(); sleep(1); $timer_seconds++; } I sometimes find this can be off by 5-10 seconds! I am guessing its the load of the server that effects the timing?? Is there anyway I can make this accurate? Thanks all for any help.

  • PHP - Using strcpsn() to protect against SQL injection?

    - by MichaelMitchell
    I am making a sort of form validation system and I need to check the SQL database to see if the username is already there. So, my question, is it effective to use a little if statement like this to protect against an attack? if (strcspn($string, "/\?!@#$%^&*()[]{}|:;<>,.\"\'-+=" == strlen($string)){ return true; } So essentially, if the string contains any of these characters, "/\?!@#$%^&*()[]{}|:;<>,.\"\'-+=", then the length will not equal that of the original $string. I am just wondering if this is sufficient to protect, or if there is more that I must do. Thanks.

  • Help with PHP MySQL join

    - by kester martinez
    Please help me to understand proper join syntax. I have table named inventory which has: trans_id trans_items items -> item_id trans_user employees -> person_id trans_date trans_comment trans_inventory As you can see above, trans_items is a foreign key in items table, and trans_user is a foreign key in employees table. Now what I want to do is to display in HTML the inventory table, but instead of displaying the item id, I want the ITEM NAME to be displayed. Here is what I have done. Please note I'm using CodeIgniter. public function getData(array $inputs) { $this->db->select('trans_items, trans_user, trans_date, trans_inventory, trans_comment'); $this->db->from('inventory'); $this->db->order_by('trans_date desc'); return $this->db->get()->result_array(); }

  • Sum of a PHP Array

    - by user1879415
    The following code displays the ordered products individual weight: $weightsql = 'select op.products_name, op.products_quantity , p.products_weight from ' . TABLE_ORDERS_PRODUCTS . ' op left join ' . TABLE_PRODUCTS . ' p on op.products_id = p.products_id where op.products_id = '.$pro['products_id']; $weightq = tep_db_query( $weightsql ); while ($weight = tep_db_fetch_array( $weightq )){ if($category_parent_id != 0)$list_items[] = $weight['products_weight'].'&nbsp;&nbsp;&nbsp;'; } This shows the wieght for each of the products ordered. What I am stuck on is instead of showing seperate weights, I need to show a total weight. For example, if the product was ordered three times, and it weighs 7kg, the code at the moment is showing: Product 7.00 7.00 7.00 How would I make it show the total weight, 21kg?
