• How can I convert HTML to pdf?

  - by Walkman

  I want to read and annotate internet articles like books on my iPad so I would like to convert HTML to PDF.

I have tried some converters I have found online but none fit the criteria above.

• Best practice PHP Form Action

  - by Rob

  Hi there i've built a new script (from scratch not a CMS) and i've done alot of work on reducing memory usage and the time it takes for the page to be displayed (caching HTML etc) There's one thing that i'm not sure about though. Take a simple example of an article with a comments section. If the comment form posts to another page that then redirects back to the article page I won't have the problem of people clicking refresh and resending the information. However if I do it that way, I have to load up my script twice use twice as much memory and it takes twice as long whilst i'm still only displaying the page once. Here's an example from my load log. The first load of the article is from the cache, the second rebuilds the page after the comment is posted. Example 1 0 queries using 650856 bytes of memory in 0.018667 - domain.com/article/1/my_article.html 9 queries using 1325723 bytes of memory in 0.075825 - domain.com/article/1/my_article/newcomment.html 0 queries using 650856 bytes of memory in 0.029449 - domain.com/article/1/my_article.html Example 2 0 queries using 650856 bytes of memory in 0.023526 - domain.com/article/1/my_article.html 9 queries using 1659096 bytes of memory in 0.060032 - domain.com/article/1/my_article.html Obviously the time fluctuates so you can't really compare that. But as you can see with the first method I use more memory and it takes longer to load. BUT the first method avoides the refresh problem. Does anyone have any suggestions for the best approach or for alternative ways to avoid the extra load (admittadely minimal but i'd still like to avoid it) whilst also avoiding the refresh problem?

• ajax html vs xml/json responses - perfomance or other reasons

  - by pedalpete

  I've got a fairly ajax heavy site and some 3k html formatted pages are inserted into the DOM from ajax requests. What I have been doing is taking the html responses and just inserting the whole thing using jQuery. My other option is to output in xml (or possibly json) and then parse the document and insert it into the page. I've noticed it seems that most larger site do things the json/xml way. Google Mail returns xml rather than formatted html. Is this due to performance? or is there another reason to use xml/json vs just retrieving html? From a javascript standpoint, it would seem injecting direct html is simplest. In jQuery I just do this jQuery.ajax({ type: "POST", url: "getpage.php", data: requestData, success: function(response){ jQuery('div#putItHear').html(response); } with an xml/json response I would have to do jQuery.ajax({ type: "POST", url: "getpage.php", data: requestData, success: function(xml){ $("message",xml).each(function(id) { message = $("message",xml).get(id); $("#messagewindow").prepend(""+$("author",message).text()+ ": "+$("text",message).text()+ ""); }); } }); clearly not as efficient from a code standpoint, and I can't expect that it is better browser performance, so why do things the second way?

• Center aligned form with equal width labels

  - by James Goodwin

  I have a very simple web form which consists of labels and input fields, however I can not seem to find a way of aligning the form in the center of the page and for the labels to have an equal width so that they appear neatly next to each other, one under the other. The structure of my page is basically: <body> <div class="form"> <form method="post"> <fieldset> <label>Mobile:</label><input type="text" name="msisdn"><br/> <label>Code:</label><input type="text" name="code"><br/> <br/> <input type="image" src="submit-button.gif" alt="Submit"> <br/> <input type="checkbox" name="ts_and_cs"><label> Accept Terms and Conditions</label> <br/><br/> </fieldset> </form> </div> </body> Usually I would fix this by doing float:left on the label fields and setting a width on the labels, however for this I need the labels and input fields to be centered on the page. Also I am not able to set the width of the page (or any containing divs) as the page will be displayed on mobile devices with different screen sizes. Any suggestions as to how best style the form? Thanks

• Form submit capture into database not working

  - by kielie

  Hi guys, I have a form that has two buttons on it, one yes, one no, and at the moment I capture the clicked button into a database, but for some reason, it doesn't always capture the clicked button, I have gone through all my code and everything seems fine, here is the form <div id="mid_prompt"> <form action="refer.php" method="post" onsubmit="return submit_form()" > <div class="prompt_container" style="float: left;"> <span class="prompt_item"><input type="image" src="images/yes.jpg" alt="submit" name="refer" value="yes" /></span> </div> </form> <form action="thank_you.php" method="post" onsubmit="return submit_form()" > <div class="prompt_container" style="float: right;"> <span class="prompt_item"><input type="image" src="images/no.jpg" alt="submit" name="refer" value="no" /></span> </div> </form> </div> I am using sessions to carry the variables all the way to the end of the forms where I then write all the data to a database, I have checked my sessions and they seem to be working fine, the only one that is giving problems is the yes/no. So basically I need it to capture that yes/no everytime. Thanx in advance!

• Can I include a robots meta tag outside of the head in HTML snippets indeded to be SSIed?

  - by Dan

  I have a number of files in my site which are not intended for independent viewing, but rather to be AJAXed into content within the site. They obviously don't meet HTML standards (no body, head, etc.) as independent entities. I would like to prevent search engines from indexing these pages, but do not have access to /robots.txt (which would be much more ideal). My question is, could I include the following at the top of these partial HTML files and get the desired results? <meta name="robots" content="noindex, noarchive"> I guess there are two parts to this question. Will this cause any rendering issues in any browsers? Will search engines (at least Google & Bing) interpret this as intended?

  This is a question about the website www.blogger.com. I am trying to modify my active template like this: I want to add a github ribbon to my template page, like the ones seen here: https://github.com/blog/273-github-ribbons I have tried pasting in the templates in the head tag and in the body tag, but in both cases I get error messages like this from the blogger site: Is it possible to add such a ribbon to a blogger site by editing the template html, and in that case, where is the correct place to paste in the code snippet?

• Should I Use Anchor, Button Or Form Submit For "Follow" Feature In Rails

  - by James

  I am developing an application in Rails 3 using a nosql database. I am trying to add a "Follow" feature similar to twitter or github. In terms of markup, I have determined that there are three ways to do this. 1) Use a regular anchor. (Github Uses This Method) <a href="/users/follow?target=Joe">Follow</a> 2) Use a button. (Twitter Uses This Method) <button href="/friendships/create/">Follow</button> 3) Use a form with a submit button. (Has some advantages for me, but I haven't see anyone do it yet.) <form method="post" id="connection_new" class="connection_new" action="/users/follow"> <input type="hidden" value="60d7b563355243796dd8496e17d36329" name="target" id="target"> <input type="submit" value="Follow" name="commit" id="connection_submit"> </form> Since I want to store the user_id in the database and not the username, options 1 and 2 will force me to do a database query to get the actual user_id, whereas option 3 will allow me to store the user_id in a hidden form field so that I don't have to do any database lookups. I can just get the id from the params hash on form submission. I have successfully got each of these methods working, but I would like to know what is the best way to do this. Which way is more semantic, secure, better for spiders, etc...? Is there a reason both twitter and github don't use forms to do this? Any guidance would be appreciated. I am leaning towards using the form method since then I don't have to query the db to get the id of the user, but I am worried that there must be a reason the big guys are just using anchors or buttons for this. I am a newb so go easy on me if I am totally missing something. Thanks!

• Lazarus Form Recovery for Safari?

  - by Cawas

  I use Lazarus a lot on Chrome and FireFox. Well, not a lot, but it's great for crashing when you're writing something online in a form that doesn't automatically save what you're writing. Plus, this should be default in every browser ANYway, and not built-in any web site (such as gmail). So, is there any such option for Safari? Does Saft do that? Just by looking at the home page, it seems to me like bloatware to Safari 4.

• How to convert a really big HTML file to PDF in Windows

  - by PeterStrange

  We have a few really large HTML files (60-100 MB) that we cannot convert to PDF with any reliability. Adobe Acrobat 9 crashes - hits the 2GB limit for applications. Open Office converts, but removes some of the anchors (). ActivePDF webgrabber crashes. Is using a 64 bit situation an option for this type of thing? I see a bunch of options out there, but can they do better than Adobe Acrobat 9 itself?

• Multiple use of a form before it is submitted

  - by OregonTrail

  I'm new to JavaScript, and trying to figure out the canonical way to do the following. I have a form with some checkboxes and a selector. Let's say the checkboxes are styles of music and the selector is for people's names. I'd like the user to be able to select the styles of music for each of the people's names and then submit the form with all of the data. For example, the user might first check off Classical, Jazz, Rock, and Pop and choose "Joe", then select Jazz, Pop, Country, and Electronica and choose "Jane". So there would have to be two different buttons for "submit person" and "submit form". I would like to: Have a list of the names and their chosen styles populate below the form, for feedback Allow the user to use the form as much as they want, and then submit all the data at the end I get the feeling that using jquery and JSON is perfect for this, but I'm not sure what search terminology to use to figure out how to do this. If it matters, the form will be processed by a Django view in Python.

• php form submit and the resend infromation screen

  - by Para

  Hello, I want to ask a best practice question. Suppose I have a form in php with 3 fields say name, email and comment. I submit the form via POST. In PHP I try and insert the date into the database. Suppose the insertion fails. I should now show the user an error and display the form filled in with the data he previously inserted so he can correct his error. Showing the form in it's initial state won't do. So I display the form and the 3 fields are now filled in from PHP with echo or such. Now if I click refresh I get a message saying "Are you sure you want to resend information?". OK. Suppose after I insert the data I don't carry on but I redirect to the same page but with the necessary parameters in the query string. This makes the message go away but I have to carry 3 parameters in the query string. So my question is: How is it better to do this? I want to not carry around lots of parameters in the query string but also not get that error. How can this be done? Should I use cookies to store the form information.

• jQuery ajax form submit - how to ensure dynamically loaded form's action is used

  - by kenny99

  Hi, i'm having a problem with dynamically loaded forms - instead of using the action attribute of the newly loaded form, my jquery code is still using the action attribute of the first form loaded. I have the following code: //generic ajax form handler - calls next page load on success $('input.next:not(#eligibility)').live("click", function(){ $(".form_container form").validationEngine({ ajaxSubmit: true, ajaxSubmitFile: $(this).attr('action'), success : function() { var url = $('input.next').attr('rel'); ajaxFormStage(url); }, failure : function() { } }); }); But when the next form is loaded, the above code does not pick up the new action attribute. I have tried adding the above code to my callback on successful ajax load (shown below), but this doesn't make any difference. Can anyone help? Many thanks function ajaxFormStage(url) { var $data = $('#main_body #content'); $.validationEngine.closePrompt('body'); //close any validation messages $data.fadeOut('fast', function(){ $data.load(url, function(){ $data.animate({ opacity: 'show' }, 'fast'); '); //generic ajax form handler - calls next page load on success $('input.next:not(#eligibility)').live("click", function(){ $(".form_container form").validationEngine({ ajaxSubmit: true, ajaxSubmitFile: $(this).attr('action'), success : function() { var url = $('input.next').attr('rel'); ajaxFormStage(url); }, failure : function() { } }); }); }); });

• C# regular expression for finding forms with input tags in HTML?

  - by johnrl

  Hi all. I have a simple problem: I want to construct a regex that matches a form in HTML, but only if the form has any input tags. Example: The following should be matched (ignoring attributes): .. <form> .. <input/> .. </form> .. But the following should not (ignoring attributes): .. <form> .. </form> .. I have tried everything from look-arounds to capture groups but it quickly gets complicated. I want to believe there is a simple regex to capture the problem. Please note that it is important that the regex pairs the opening and closing tags according to the HTML code which means the following does not work: <form>.+<input/>.+</form> because it matches wrongly like this: .. <form> <--- This is wrongly matched as the opening tag .. </form> <form> <-- This is the correct opening tag of the correct form .. <input/> .. </form> <--- This is matched as the closing tag ..

• Is it practical to have perfect validation score on HTML?

  - by Truth

  I was in a heated discussion the other day, about whether or not it's practical to have a perfect validation score on any HTML document. By practical I mean: Does not take a ridiculous amount of time compared to it's almost-perfect counterpart. Can be made to look good on older browsers and to be usable on very old browsers. Justifies the effort it may take to do so (does it come with some kind of reward on SEO/Usability/Accessibility that cannot be achieved in a simpler way with almost-perfect validation) So basically, is perfect validation score practical on any HTML document?

• Do I have to learn html and javascript to create web applications?

  - by vainolo

  I am an experienced Java programmer, and I want to create a complex web application requiring dynamic pages, drawings, etc (take SO as an example). Do I have to learn javascript/html in order to create such an application? It is not that I don't want to learn another language (I've done this before), but technology on the javascript environment seems to change so fast that when you finish learning one framework it is already obsolete. I have checked a number of java framework for web development (spring, play), but not deeply. So can these frameworks (or other possible java frameworks that I'm not aware of) be used without learning html/javascript? I also have some python experience. So if I can do the app in python it is also an option.

• Zend Framework Form Element Validators - validate a field even if not required

  - by Jeremy Hicks

  Is there a way to get a validator to fire even if the form element isn't required? I have a form where I want to validate the contents of a texbox (make sure not empty) if the value of another form element, which is a couple of radio buttons, has a specific value selected. Right now I'm doing this by overriding the isValid() function of my form class and it works great. However, I'd like to move this to either its on validator or use the Callback validator. Here's what I have so far, but it never seems to get called unless I change the field to setRequired(true) which I don't want to do at all times, only if the value of the other form element is set to a specific value. // In my form class's init function $budget = new Zend_Form_Element_Radio('budget'); $budget->setLabel('Budget') ->setRequired(true) ->setMultiOptions($options); $budgetAmount = new Zend_Form_Element_Text('budget_amount'); $budgetAmount->setLabel('Budget Amount') ->setRequired(false) ->addFilter('StringTrim') ->addValidator(new App_Validate_BudgetAmount()); //Here is my custom validator (incomplete) but just testing to see if it even gets called. class App_Validate_BudgetAmount extends Zend_Validate_Abstract { const STRING_EMPTY = 'stringEmpty'; protected $_messageTemplates = array( self::STRING_EMPTY => 'please provide a budget amount' ); public function isValid($value) { echo 'validating...'; var_dump($value); return true; } }

• How to wrap Ruby strings in HTML tags

  - by Jason H.

  Hi all: I'm looking for help on two things. 1) I'm looking for a way for Ruby to wrap strings in HTML. I have a program I'm writing that generates a Hash of word frequencies for a text file and I want to take the results and place it into an HTML file rather than print to STDOUT. I'm thinking each string needs to be wrapped in an HTML paragraph tag using readlines() or something, but I can't quite figure it out. Then, once I've wrapped the strings in HTML 2) I want to write to an empty HTML file. Right now my program looks like: filename = File.new(ARGV[0]).read().downcase().scan(/[\w']+/) frequency = Hash.new(0) words.each { |word| frequency[word] +=1 } frequency.sort_by { |x,y| y }.reverse().each{ |w,f| puts "#{f}, #{w}" } So if we ran a text file through this and received: 35, the 27, of 20, to 16, in # . . . I'd want to export to an HTML file that wraps the lines like: <p>35, the</p> <p>27, of</p> <p>20, to</p> <p>16, in</p> # . . . Thanks for any tips in advance!

• How can I theme custom form(drupal 6.x)

  - by Andrew

  DRUPAL 6.X I have this custom form constructor inside my custom module which is invoke through ajax request. I’m attempting to theme this form with the template file reside in my theme directory. For that matter, I’ve registered my theme inside template.php file which reside in my theme folder. Here’s how this file looks – function my_theme() { return array( 'searchdb' => array( 'arguments' => array('form' => NULL), 'template' => 'searchform', ) ); } And the following is the excerpt of module code – function test_menu() { $my_form['searchdb'] = array( 'title' => 'Search db', 'page callback' => 'get_form', 'page arguments' => array(0), 'access arguments' => array('access content'), 'type' => MENU_CALLBACK, ); return $my_form; } function get_form($formtype){ switch($formtype){ case 'searchdb' : echo drupal_get_form('searchdb'); break; } } function searchdb(){ $form['customer_name'] = array( '#type' => 'textfield', '#title' => t('Customer Name'), '#size' => 50, '#attributes' => array('class' => 'name-textbox'), ); return $form; } As you can imagine, this is not working at all. Just to test if my theme is even registered, I’ve also tested with theme function but, it’s not called. I've checked template file name and form-id(through the outputted html source) and everything seems ok. I would be glad if anyone could point me to the right direction.

• html in do_GET() method of a simple Python webserver

  - by Meeri_Peeri

  I am relatively new to Python but have been doing a lot of different things with it recently and I am liking it a lot. However, I ran into trouble/block with the following code. import http.server import socketserver import glob import random class Server(http.server.SimpleHTTPRequestHandler): def do_GET(self): self.send_response(200, 'OK') self.send_header('Content-type', 'html') self.end_headers() self.wfile.write(bytes("<html> <head><title> Hello World </title> </head> <body>", 'UTF-8')) images = glob.glob('*.jpg') rand = random.randint(0,len(images)-1) imagestring = "<img src = \"" + images[rand] + "\" height = 1028 width = 786 align = \"right\"/> </body> </html>" self.wfile.write(bytes(imagestring, 'UTF-8')) def serve_forever(port): socketserver.TCPServer(('', port), Server).serve_forever() if __name__ == "__main__": Server.serve_forever(8000) What I am trying to do here is grab a random image from multiple images in the directory and add it into the response to a web request. The code works fine but when I access the server via browser, the image is not displayed. The html of the page is as intended though. The permissions on the files are 755. Also I tried to create an index.html file in the do_GET method. That didn't work either. I mean the index.html was generated fine, but the response in the browser this time did not show anything (not even the hello world in the title). Am I missing anything very simple here? I was thinking should I overload the handle_request of the underlying SocketServer.BaseServer as the documentation says you should never override BaseHTTPServer's handle() method and should rather override the corresponding do_* method?
