  • How could I parse this HTML file?

    - by Sergio Tapia
    <div id="main"> <style type="text/css"> </style> <script language="JavaScript"> </script> <p style="margin: 0pt 0pt 0.5em;"><b>Media from&nbsp;<a onclick="(new Image()).src='/rg/find-media-title/media_strip/images/b.gif?link=/title/tt0087538/';" href="/title/tt0087538/">The Karate Kid</a> (1984)</b></p> <style type="text/css"> </style> <table style="border-collapse: collapse;"> </table> </div> I need to somehow extract the href value of the (new Image()). How exactly would I accomplish this with HtmlAgilityPack? I'm new to it, and so far I haven't found a useful tutorial on how to effectively use it for parsing. Thanks for the help!

  • PHP and curl for fetching currency rate from Yahoo Finance

    - by gregj
    Hello, I wrote the following php snippet to fetch the currency conversion rate from Yahoo Finance.Im using curl to fetch the data. Suppose, i want to convert from US dollars (USD) to Indian National Rupee (INR),then the url is http://in.finance.yahoo.com/currency/convert?amt=1&from=USD&to=INR&submit= and the Indian Rupee value is shown as 45.225. However,if i run my code, the value im getting is 452.25. Why this discrepancy ? <?php $amount = $_GET['amount']; $from = $_GET['from']; $to = $_GET['to']; $url = "http://in.finance.yahoo.com/currency/convert?amt=".$amount."&from=".$from."&to=".$to; $handle = curl_init($url); curl_setopt ($handle, CURLOPT_RETURNTRANSFER, true); $data = curl_exec($handle); if(preg_match_all('/<td class="yfnc_tabledata1"><b>(?:[1-9]\d+|\d)(?:\.\d\d)?/',$data,$matches)) { print_r($matches[0][1]); } else { echo "Not found !"; } curl_close($handle); ?> Is there something wrong with my regex ? Please help. Thank You.

  • Flash As3.0 PHP Variables?

    - by user311421
    Is it possible to make php variables public and accessible anywhere on the timeline? The script I included works fine if I set it as the document class only (it won't work if I try importing it). The variables pass the text to dynamic text fields on the main timeline. The problem: It will pull the information and display it when the SWF first loads but if I move to my second frame and then back it erases the information. It also will not pass any variables to the second frame. The only way to see the variables after going back to the first frame is to reload the whole SWF. I'm pretty much stuck at this point trying to make the variables persistent through all frames. this is my code: package { import flash.display.MovieClip; import flash.events.*; import flash.net.*; import flash.display.Stage; public class Main extends MovieClip { public function Main() { var request:URLRequest = new URLRequest("http://localhost/mytest2/dataLayer.php"); request.method = URLRequestMethod.GET; var loader:URLLoader = new URLLoader(); loader.dataFormat = URLLoaderDataFormat.VARIABLES; loader.addEventListener(Event.COMPLETE, completeHandler); loader.load(request); function completeHandler(evt:Event) { var username = evt.target.data.username; var pclass = evt.target.data.pclass; var hpoints = evt.target.data.hpoints; var spoints = evt.target.data.spoints; username_txt.text = username; class_txt.text = pclass; hpoints_txt.text = hpoints; spoints_txt.text = spoints; } } } }

  • Making alpha PNGs with PHP GD

    - by WiseDonkey
    Hello, I've got a problem making alpha PNGs with PHP GD. I don't have imageMagik etc. Though the images load perfectly well in-browser and in GFX programs, I'm getting problems with Flash AS3 (actionscript) understanding the files. It complains of being an unknown type. But, exporting these files from Fireworks to the same spec works fine. So I'm suggesting it's something wrong with the formatting in PHP GD. There seems to be a number of ways of doing this, with several similar functions; so maybe this isn't right? $image_p = imagecreatetruecolor($width_orig, $height_orig); $image = imagecreatefrompng($filename); imagealphablending($image_p, false); ImageSaveAlpha($image_p, true); ImageFill($image_p, 0, 0, IMG_COLOR_TRANSPARENT); imagealphablending($image_p, true); imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width_orig, $height_orig, $width_orig, $height_orig); imagepng($image_p, "new2/".$filename, 0); imagedestroy($image_p); This just takes files it's given and puts them into new files with a specified width/height - for this example it's same as original but in production it resizes, which is why I'm resampling.

  • Getting text at clicked location in an HTML element

    - by Marc
    I have a div element containing some text. When the user clicks a word inside that div I'd like to highlight just that word. In order to do this I need to know what character position in the text the click occurred at, so I can then locate nearby whitespace and insert some formatting around the word. Finding out where the click occurred within the text is the trick here. Is that kind of thing possible?

  • Help a Beginner with a PHP based Login System

    - by Brian Lang
    I'm a bit embarrassed to say, but I've run into issue with creating a PHP based login system. I'm using a site template to handle the looks of the the login process, so I will spare you the code. Here is my thought process on how to handle the login: Create a simple login.php file. On there will be a form whose action is set to itself. It will check to see if the submit has been clicked, and if so validate to make sure the user entered a valid password / username. If they do, set a session variable save some login info (username, NOT password), and redirect them to a restricted area. If the login info isn't valid, save an error message in a session variable, display error message giving further instruction, and wait for the user to resubmit. Here is a chunk of what I have - hopefully one of you experts can see where I've gone wrong, and give me some insight: if(isset($_POST['submit'])) { if(!empty($_POST['username']) AND !empty(!$_POST['password'])) { header("Location: http://www.google.com"); } else { $err = 'All the fields must be filled in!'; } } if($err) { $_SESSION['msg']['login-err'] = $err; } ? Now the above is just an example - the intent of the above code is to process user input, with the script validating simply that the user has given input for username and password. If they have, I would like them, in this case, to be redirected to google.com (for the sake of this example). If not, save an error message. Given my current code, the error message will display perfectly, however if the user submits and has something entered for the username and password, the page simply doesn't redirect. I'm sure this is a silly question, but I am a beginner, and well, to be honest, a bit buzzed right now. Thanks so much!

  • PHP autoloader: ignoring non-existing include

    - by Bart van Heukelom
    I have a problem with my autoloader: public function loadClass($className) { $file = str_replace(array('_', '\\'), '/', $className) . '.php'; include_once $file; } As you can see, it's quite simple. I just deduce the filename of the class and try to include it. I have a problem though; I get an exception when trying to load a non-existing class (because I have an error handler which throws exceptions). This is inconvenient, because it's also fired when you use class_exists() on a non-existing class. You don't want an exception there, just a "false" returned. I fixed this earlier by putting an @ before the include (supressing all errors). The big drawback with this, though, is that any parser/compiler errors (that are fatal) in this include won't show up (not even in the logs), resulting in a hard to find bug. What would be the best way to solve both problems at once? The easiest way would be to include something like this in the autoloader (pseudocode): foreach (path in the include_path) { if (is_readable(the path + the class name)) readable = true; } if (!readable) return; But I worry about the performance there. Would it hurt a lot? (Solved) Made it like this: public function loadClass($className) { $file = str_replace(array('_', '\\'), '/', $className) . '.php'; $paths = explode(PATH_SEPARATOR, get_include_path()); foreach ($paths as $path) { if (is_readable($path . '/' . $file)) { include_once $file; return; } } }

  • Printing HTML blocks

    - by Lem0n
    I have a page with a few tables that I want to be printable. I want the following behaviour: 1) Add a page break if the next table fits in a single page, but won't fit in the current page (because of other stuff already printed on this page) 2) Print the "table header" again in case it's needed to break a table (I guess it's the default behaviour) Any ideas specially on the first issue? Maybe some CSS can help? I'll give on example. I have a page with 4 tables. All of them with 10 lines, except the third one, with 50 lines. The first and second goes on the first page. Since the third one won't fit in the same page, but will fit in a page alone, it's printed on a page alone... and then the forth table is printed on the third page (in case it doesn't fit together in the second page). But, if the third page had 300 lines and would be broke anyway, it could have started to be print in the first page.

  • Pass checkbox values with Jquery to PHP and display result in div

    - by user1343955
    I want to filter realtime results with jQuery (just like on this site http://shop.www.hi.nl/hi/mcsmambo.p?M5NextUrl=RSRCH). So when someones checks a checkbox the results should update realtime (in a div). Now I'm a newbie with jQuery and I've tried lots of examples but I can't get it to work. Here's my code, could anyone tell what I'm doing wrong? Thank you very much! HTML <div id="c_b"> Kleur:<br /> <input type="checkbox" name="kleur[1]" value="Blauw"> Blauw <br /> <input type="checkbox" name="kleur[2]" value="Wit"> Wit <br /> <input type="checkbox" name="kleur[3]" value="Zwart"> Zwart <br /> <br /> Operating System:<br /> <input type="checkbox" name="os[1]" value="Android"> Android <br /> <input type="checkbox" name="os[2]" value="Apple iOS"> Apple iOS <br /> </div> <div id="myResponse">Here should be the result</div> jQuery function updateTextArea() { var allVals = []; $('#c_b :checked').each(function() { allVals.push($(this).val()); }); var dataString = $(allVals).serialize(); $.ajax({ type:'POST', url:'/wp-content/themes/u-design/filteropties.php', data: dataString, success: function(data){ $('#myResponse').html(data); } }); } $(document).ready(function() { $('#c_b input').click(updateTextArea); updateTextArea(); }); PHP //Just to see if the var passing works echo var_export($_POST);

  • PHP Unicode character questions

    - by user271619
    Here's a link I found, which even has a character I need to play with for other projects of mine. http://www.fileformat.info/info/unicode/char/2446/index.htm There is a box with the Title of: "Encodings" on that page. And I am wondering about some of the rows. I obviously need a course on this sort of thing, but I'm wondering what the difference is between "HTML Entity (decimal)" and "HTML Entity (hex)". The funny thing is, which confuses me, I throw those characters on a web page, and they display fine. But I haven't specified any UTF-8 encoding in the php page. <?php $string1 = '&#x2446;'; $string2 = '&#9286;'; echo $string1; echo '<br>'; echo $string2; ?> Does the browser know how to display both automatically? And to make it weirder, I can only see those characters on my Mac, in Firefox. But my windows box doesn't want to show them. I've tested it in chrome, and firefox. Do I need to tell the browsers to view them correctly? Or is it an operating system modification?

  • How to Avoid PHP Object Nesting/Creation Limit?

    - by Will Shaver
    I've got a handmade ORM in PHP that seems to be bumping up against an object limit and causing php to crash. Here's a simple script that will cause crashes: <? class Bob { protected $parent; public function Bob($parent) { $this->parent = $parent; } public function __toString() { if($this->parent) return (string) "x " . $this->parent; return "top"; } } $bobs = array(); for($i = 1; $i < 40000; $i++) { $bobs[] = new Bob($bobs[$1 -1]); } ?> Even running this from the command line will cause issues. Some boxes take more than 40,000 objects. I've tried it on Linux/Appache (fail) but my app runs on IIS/FastCGI. On FastCGI this causes the famous "The FastCGI process exited unexpectedly" error. Obviously 20k objects is a bit high, but it crashes with far fewer objects if they have data and nested complexity. Fast CGI isn't the issue - I've tried running it from the command line. I've tried setting the memory to something really high - 6,000MB and to something really low - 24MB. If I set it low enough I'll get the "allocated memory size xxx bytes exhausted" error. I'm thinking that it has to do with the number of functions that are called - some kind of nesting prevention. I didn't think that my ORM's nesting was that complicated but perhaps it is. I've got some pretty clear cases where if I load just ONE more object it dies, but loads in under 3 seconds if it works.

  • Error handling in PHP

    - by Industrial
    Hi guys, We're building a PHP app based on Good old MVC (codeigniter framework) and have run into trouble with a massive chained action that consists of multiple model calls, that together is a part of a big transaction to the database. We want to be able to do a list of actions and get a status report of each one back from the function, whatever the outcome is. Our first initial idea was to utilize the exceptions of PHP5, but since we want to also need status messages that doesnt break the execution of the script, this was our solution that we came up with. It goes a little something like this: $sku = $this->addSku( $name ); if ($sku === false) { $status[] = 'Something gone terrible wrong'; $this->db->trans_rollback(); return $status; } $image= $this->addImage( $filename); if ($image=== false) { $error[] = 'Image could not be uploaded, check filesize'; $this->db->trans_rollback(); return $status; } Our controller looks like this: $var = $this->products->addProductGroup($array); if (is_array($var)) { foreach ($var as $error) { echo $error . '<br />'; } } It appears to be a very fragile solution to do what we need, but it's neither scalable, neither effective when compared to pure PHP exceptions for instance. Is this really the way that this kind of stuff generally is handled in MVC based apps? Thanks!

  • random data using php & mysql

    - by Prakash
    I have mysql database structure like below: CREATE TABLE test ( id int(11) NOT NULL auto_increment, title text NULL, tags text NULL, PRIMARY KEY (id) ); data on field tags is stored as a comma separated text like html,php,mysql,website,html etc... now I need create an array that contains around 50 randomly selected tags from random records. currently I am using rand() to select 15 random mysql data from database and then holding all the tags from 15 records in an array. Then I am using array_rand() for randomizing the array and selecting only 50 random records. $query=mysql_query("select * from test order by id asc, RAND() limit 15"); $tags=""; while ($eachData=mysql_fetch_array($query)) { $additionalTags=$eachData['tags']; if ($tags=="") { $tags.=$additionalTags; } else { $tags.=$tags.",".$additionalTags; } } $tags=explode(",", $tags); $newTags=array(); foreach ($tags as $tag) { $tag=trim($tag); if ($tag!="") { if (!in_array($tag, $newTags)) { $newTags[]=$tag; } } } $random_newTags=array_rand($newTags, 50); Now I have huge records on the database, and because of that; rand() is performing very slow and sometimes it doesn't work. So can anyone let me know how to handle this situation correctly so that my page will work normally.

  • Problems with utf-8 encoding in php

    - by Addsy
    Hi, Another utf-8 related problem I believe... I am using php to update data in a mysql db then display that data elsewhere in the site. Previously I have run into utf-8 problems before where special characters are displayed as question marks when viewed in a browser but this one seems slightly different. I have a number of records to enter that contain the è character. If I enter this directly in the db then it appears correctly on the page so I take this to mean that utf-8 content is being output correctly. However when I try and update the values in the db through php, then the è character is replaced. What appears instead is & Atilde ; & uml ; (without the spaces) which appears in the browser as è I have the tables in the database set to use UTF-8. I believe this is correct cos, as mentioned, if I update the db through phpMyAdmin, its all ok. Similarly I have set the character encoding for the page which seems to be correct. I am also running the sql statement "SET NAMES 'utf8';" before trying to update the db. Anyone have any other ideas as to where the problem may lie? Many thanks

  • php - sort and delete duplicates?

    - by c41122ino
    I've got an array that looks like this: Array ( [0] => Array ( num => 09989, dis => 20 ) [1] => Array ( num => 09989, dis => 10 ) [2] => Array ( num => 56676, dis => 15 ) [3] => Array ( num => 44533, dis => 20 ) [4] => Array ( num => 44533, dis => 50 ) ) First, I'm trying to sort them by num, and can't seem to get the usort example from php.net working here. It simply doesn't appear to be sorting... I'm also trying to delete the array element if it's a duplicate and whose dis value is higher than the other one. So, based on the example above, I'm trying to create: Array ( [0] => Array ( num => 09989, dis => 10 ) [1] => Array ( num => 44533, dis => 20 ) [2] => Array ( num => 56676, dis => 15 ) ) This is the code from php.net: function cmp($a, $b) { if ($a == $b) { return 0; } return ($a < $b) ? -1 : 1; }
