  • Scraping non-absolute URL

    - by cooldude
    I am trying to scrape www.weather.bm. I want all 10 radar images, but I can only get one (the image updates regularly) and it's not a absolute image url. I was hoping I could use the image as a image slideshow like the link but dont know how. Also, how can I remove images/Radarlegend.png? I just need the radar images. Here is my code: include('simple_html_dom.php'); $html = file_get_html('http://www.weather.bm/radarMobile.asp'); foreach($html->find('img') as $element) echo $element->src . '<br>' My output is: <div id="main"> images/Radar/CurrentRadarAnimation_100km_sri/100km_sri-radar-2011-01-04-1556.jpg<br>images/Radarlegend.png<br></div> </div>

  • Want to open Shadowbox gallery directly through Wordpress Navigation Menu

    - by Kevin A.
    I want to be able to open my shadowbox gallery in wordpress by directly clicking the portfolio link in the navbar. Right now it either opens the portfolio page I made with the gallery in it or opens images separately (without shadowbox), this was because I tried adding html to the Nav Label in the wordpress dashboard. Basically want to be able to add this html to the link in the menu dashboard while having the one PORTFOLIO link: <a href="/portfolio_images/fashion/01.jpg" rel="shadowbox[fashion]"> <a href="/portfolio_images/fashion/02.jpg" rel="shadowbox[fashion]"> <a href="/portfolio_images/fashion/03.jpg" rel="shadowbox[fashion]"> Thanks Main page with nav links

  • Placing .htaccess file in var/www folder messes my website up...

    - by Camran
    I am playing with mod_rewrite now, and have successfully enabled it. However, I need to put a htaccess file inside var/www/ in order to achieve what I want, which is to rename Urls simply... When I place it my website becomes very strange and nothing basically works... Is there any code I need to put into the htaccess file in order for things to act normally? Here is the htaccess file I have so far: Options +FollowSymLinks Options +Indexes RewriteEngine On RewriteCond %{REQUEST_URI} !^/ad\.php RewriteRule ^(.*)$ ad.php?ad_id=$1 [L] My DocumentRoot is also set to var/www/ and my entire website root is there... (index.html etc etc)... What am I missing about the htaccess? If you need more input let me know...

  • Submit form without page reloading

    - by Camran
    I have a classifieds website, and on the page where ads are showed, I am creating a "Send a tip to a friend" form... So anybody who wants can send a tip of the ad to some friends email-adress. I am guessing the form must be submitted to a php page right? <form name='tip' method='post' action='tip.php'> Tip somebody: <input name="tip_email" type="text" size="30" onfocus="tip_div(1);" onblur="tip_div(2);"/> <input type="submit" value="Skicka Tips"/> <input type="hidden" name="ad_id" /> </form> When submitting the form, the page gets reloaded... I don't want that... Is there any way to make it not reload and still send the mail? Preferrably without ajax or jquery... Thanks

  • Form Login Error

    - by ilp
    I'm having issues with a login form for my website. At the top of the login.php form I have this <?php if (isset($_SESSION['username'])){ header("Location: http://myurl/"); die;}?> <?php require 'includes/dbconnect.php' ; ?> <?php require 'includes/header.php'; ?> and when login is successful I redirect them to header('Location: http://myrul/'); Header.php has <?php session_start(); ?> at the top. When I tried to login, I get this error message: Warning: Cannot modify header information - headers already sent by (output started at /path/to/file/login.php:7) in /path/to/file/login.php on line 39. login.php:7 == <?php require 'includes/header.php'; ?> while Line 39 in login.php is == header('Location: http://myrul/'); Please where is the problem

  • Long connection times from PHP to MySQL on EC2

    - by Erik Giberti
    I'm having an intermittent issue connecting to a database slave with InnoDB. Intermittently I get connections taking longer than 2 seconds. These servers are hosted on Amazon's EC2. The app server is PHP 5.2/Apache running on Ubuntu. The DB slave is running Percona's XtraDB 5.1 on Ubuntu 9.10. It's using an EBS Raid array for the data storage. We already use skip name resolve and bind to address 0.0.0.0. This is a stub of the PHP code that's failing $tmp = mysqli_init(); $start_time = microtime(true); $tmp-options(MYSQLI_OPT_CONNECT_TIMEOUT, 2); $tmp-real_connect($DB_SERVERS[$server]['server'], $DB_SERVERS[$server]['username'], $DB_SERVERS[$server]['password'], $DB_SERVERS[$server]['schema'], $DB_SERVERS[$server]['port']); if(mysqli_connect_errno()){ $timer = microtime(true) - $start_time; mail($errors_to,'DB connection error',$timer); } There's more than 300Mb available on the DB server for new connections and the server is nowhere near the max allowed (60 of 1,200). Loading on both servers is < 2 on 4 core m1.xlarge instances. Some highlights from the mysql config max_connections = 1200 thread_stack = 512K thread_cache_size = 1024 thread_concurrency = 16 innodb-file-per-table innodb_additional_mem_pool_size = 16M innodb_buffer_pool_size = 13G Any help on tracing the source of the slowdown is appreciated. [EDIT] I have been updating the sysctl values for the network but they don't seem to be fixing the problem. I made the following adjustments on both the database and application servers. net.ipv4.tcp_window_scaling = 1 net.ipv4.tcp_sack = 0 net.ipv4.tcp_timestamps = 0 net.ipv4.tcp_fin_timeout = 20 net.ipv4.tcp_keepalive_time = 180 net.ipv4.tcp_max_syn_backlog = 1280 net.ipv4.tcp_synack_retries = 1 net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 net.ipv4.tcp_rmem = 4096 87380 16777216 net.ipv4.tcp_wmem = 4096 87380 16777216 [EDIT] Per jaimieb's suggestion, I added some tracing and captured the following data using time. This server handles about 51 queries/second at this the time of day. The connection error was raised once (at 13:06:36) during the 3 minute window outlined below. Since there was 1 failure and roughly 9,200 successful connections, I think this isn't going to produce anything meaningful in terms of reporting.

We had been running the default value (50) and increased it to 150. We also raised the kernel value /proc/sys/net/core/somaxconn (maximum socket connections) to 256 on both the application and database server from the default 128. We did see some elevation in processor utilization as a result but still received connection timeouts.

  • As a web designer, which language should I learn first for my feature career? (PHP or JavaScript) [closed]

    - by kdevs3
    Possible Duplicates: Best Programming Language for Web Development How can I choose a web development language? What language will you choose if you are going to build something big? What is the right option of programming languages and tools for building our website? What is the easiest web programing language at....? Well, I'm more of a basic web designer. I know the easy stuff pretty well. (Ya know, html, css) But I've been trying to take it to the next step and I'm contemplating about what I should learn that will help me out the most in my future web design/programming career, should it be JavaScript or maybe I should try to learn a back end programming language such as PHP. Lately, I have been hearing about a lot how JavaScript is so great and useful now, because of libraries such as jQuery and what possibility's it can bring by using Node.js and other frameworks. I've only learned the most basic of JavaScript and used some jQuery (mostly plugins) so i wouldn't know at all of what it can actually do. Would JS being so popular as it is now and useful, be a reason to stick with JavaScript and only learn it that for now? Or as a web designer, how important would it be to learn how to make a web application/website operate and functional, and know how to work with servers, etc? (Such as getting forms to work and sending data to the server and back) I've took a look at frameworks such as Code Igniter before, and looks really simple to get started with if I try to learn PHP, But I'm not sure how important it is for my career and what I would gain out of it. I'm asking because I can't decide what I should learn first. When I select it, I really want to take my time and learn the language. I don't want to spend time on learning multiple languages at the same time, so I need to pick wisely. I'm trying to turn the right direction so my career can hopefully be successful in the feature. (If money/gaining a job asked if its important, then its a yeah, it is a bit) I'm hoping I can get opinions and suggestions on this question, thanks for giving me your thoughts also.

  • web vs desktop? (php vs c++?)

    - by Dhaivat Pandya
    I need to write a simple file transfer mechanism (that isn't ftp). Firstly, it must have a GUI. Secondly, it must not be dropbox. Third, it may not use any paid libraries, and hopefully, it uses open source components. The question that came to my mind is, where is everyone moving, from desktop to web, or from web to desktop? Would it be more useful to be experienced in say, C++ than in PHP (or vice versa)?

  • Ideal web application framework for newcomers and whether it is better to use Java or PHP based framework?

    - by Pawan
    My primary question is whether a Java based web application framework is better or a PHP based one and why? Moreover, if I were just starting web development then what would be some ideal frameworks to start with, considering I may want to make a full CMS out of it later? I am not looking for a 'best', rather some good recommendations as I understand that CodeIgnitor has not got a long way to go from here : http://heybigname.com/2012/05/06/why-codeigniter-is-dead/

  • Are SQL Injection vulnerabilities in a PHP application acceptable if mod_security is enabled?

    - by Austin Smith
    I've been asked to audit a PHP application. No framework, no router, no model. Pure PHP. Few shared functions. HTML, CSS, and JS all mixed together. I've discovered numerous places where SQL injection would be easily possible. There are other problems with the application (XSS vulnerabilities, rampant inline CSS, code copy-pasted everywhere) but this is the biggest. Sometimes they escape inputs, not using a prepared query or even mysql_real_escape_string(), mind you, but using addslashes(). Often, though, their queries look exactly like this (pasted from their code but with columns and variable names changed): $user = mysql_query("select * from profile where profile_id='".$_REQUEST["profile_id"]."'"); The developers in question claimed that they were unable to hack their application. I tried, and found mod_security to be enabled, resulting in HTTP 406 for some obvious SQL injection attacks. I believe there to be sophisticated workarounds for mod_security, but I don't have time to chase them down. They claim that this is a "conceptual" matter and not a "practical" one since the application can't easily be hacked. Their internal auditor agreed that there were problems, but emphasized the conceptual nature of the issues. They also use this conceptual/practical argument to defend against inline CSS and JS, absence of code organization, XSS vulnerabilities, and massive amounts of repetition. My client (rightly so, perhaps) just wants this to go away so they can launch their product. The site works. You can log in, do what you need to do, and things are visibly functional, if slow. SQL Injection would indeed be hard to do, given mod_security. Further, their talk of "conceptual vs. practical" is rhetorically brilliant, considering that my client doesn't understand web application security. I worry that they've succeeded in making me sound like an angry puritan. In many ways, this is a problem of politics, not technology, but I am at a loss. As a developer, I want to tell them to toss the whole project and start over with a new team, but I face a strong defense from the team that built it and a client who really needs to ship their product. Is my position here too harsh? Even if they fix the SQL Injection and XSS problems can I ever endorse the release of an unmaintainable tangle of spaghetti code?

  • Is there any free host which supports php and mySQL in utf-8? [closed]

    Possible Duplicate: How to find web hosting that meets my requirements? Is there any free host which supports php and mySQL queries in utf-8? I've already tried to use x10hosting and 000webhosting, but they don't support utf8 mysql queries (got mojibake). The default encoding of mysql in both sites is latin-1, and you're not able to change that. Is there any other free host that fully supports utf-8?

  • Is there a Railstutorial-quality tutorial for a PHP framework?

    - by tnorthcutt
    Is there a tutorial along the lines of Michael Hartl's Rails Tutorial for a (widely used) PHP framework? Obviously there are tons of tutorials for e.g. Codeigniter, CakePHP, Symfony, etc., but I haven't been able to find one that is as extensive as Rails Tutorial is. Ideally, I'd like something that takes you from nothing to building a complete, functioning application with at least a decent amount of complexity.

  • Should I close database connections after use in PHP?

    - by Sprottenwels
    I wonder if I should close any unnecessary database connection inside of my PHP scripts. I am aware of the fact that database connections are closed implicitly when the block stops executing and 'manually' closing the connections could kinda bloat the codebase with unnecessary code. But shouldn't I do so in order to make by code as readable and as easy understandable as possible, while also preventing several possible issues during run time? Also, if I would do, would it be enough to unset() my database object?

  • Need Java Swing HTML canvas with support for integrated swing controls

    I would like to create an application in swing in the style of web 2.0 but have the power and functionality of a thick client. I know substance and some other look and feels help with this some, but I was wondering if there is a way I can actually use some kind of html panel / canvas to create the content in html, embedding swing controls in the rendering so as to still use listeners and get the functionality. Anybody know of a way to do this?
