  • Submit WordPress form programmatically

    - by songdogtech
    How can I let a user access a WordPress protected page with a URL that will submit the password in the form below? I want to be able to let a user get to a password protected WordPress page without needing to type the password, so when they go to the page, the password is submitted by a POST URL on page load. This not intended to be secure in any respect; I'll need to hardcode the password in the URL and the PHP. It's just for simplicity for the user, and once they're in, the cookie will let them in for 10 more days. I will select the particular user with separate PHP function that determines their IP or WordPress login status. I used Wireshark to find the POST string: post_password=mypassword&Submit=Submit but using this URL mydomain.com/wp-pass.php?post_password=mypassword&Submit=Submit gives me a blank page. This is the form: <form action="http://mydomain.com/wp-pass.php" method="post"> Password: <input name="post_password" type="password" size="20" /> <input type="submit" name="Submit" value="Submit" /></form> This is wp-pass.php: <?php require( dirname(__FILE__) . '/wp-load.php'); if ( get_magic_quotes_gpc() ) $_POST['post_password'] = stripslashes($_POST['post_password']); setcookie('wp-postpass_' . COOKIEHASH, $_POST['post_password'], time() + 864000, COOKIEPATH); wp_safe_redirect(wp_get_referer()); ?> What am I doing wrong? Or is there a better way to let a user into a password protected page automatically?

  • Why use bin2hex when inserting binary data from PHP into MySQL?

    - by Atli
    I heard a rumor that when inserting binary data (files and such) into MySQL, you should use the bin2hex() function and send it as a HEX-coded value, rather than just use mysql_real_escape_string on the binary string and use that. // That you should do $hex = bin2hex($raw_bin); $sql = "INSERT INTO `table`(`file`) VALUES (X'{$hex}')"; // Rather than $bin = mysql_real_escape_string($raw_bin); $sql = "INSERT INTO `table`(`file`) VALUES ('{$bin}')"; It is supposedly for performance reasons. Something to do with how MySQL handles large strings vs. how it handles HEX-coded values However, I am having a hard time confirming this. All my tests indicate the exact oposite; that the bin2hex method is ~85% slower and uses ~24% more memory. (I am testing this on PHP 5.3, MySQL 5.1, Win7 x64 - Using a farily simple insert loop.) For instance, this graph shows the private memory usage of the mysqld process while the test code was running: Does anybody have any explainations or reasources that would clarify this? Thanks.

  • Grails UrlMappings with .html

    - by Glennn
    I'm developing a Grails web application (mainly as a learning exercise). I have previously written some standard Grails apps, but in this case I wanted to try creating a controller that would intercept all requests (including static html) of the form: <a href="/testApp/testJsp.jsp">test 1</a> <a href="/testApp/testGsp.gsp">test 2</a> <a href="/testApp/testHtm.htm">test 3</a> <a href="/testApp/testHtml.html">test 4</a> The intent is to do some simple business logic (auditing) each time a user clicks a link. I know I could do this using a Filter (or a range of other methods), however I thought this should work too and wanted to do this using a Grails framework. I set up the Grail UrlMappings.groovy file to map all URLs of that form (/$myPathParam?) to a single controller: class UrlMappings { static mappings = { "/$controller/$action?/$id?"{ constraints { } } "/$path?" (controller: 'auditRecord', action: 'showPage') "500"(view:'/error') } } In that controller (in the appropriate "showPage" action) I've been printing out the path information, for example: def showPage = { println "params.path = " + params.path ... render(view: resultingView) } The results of the println in the showPage action for each of my four links are testJsp.jsp testGsp.gsp testHtm.htm testHtml Why is the last one "testHtml", not "testHtml.html"? In a previous (Stack Overflow query) Olexandr encountered this issue and was advised to simply concatenate the value of request.format - which, indeed, does return "html". However request.format also returns "html" for all four links. I'm interested in gaining an understanding of what Grails is doing and why. Is there some way to configure Grails so the params.path variable in the controller shows "testHtml.html" rather than stripping off the "html" extension? It doesn't seem to remove the extension for any other file type (including .htm). Is there a good reason it's doing this? I know that it is a bit unusual to use a controller for static html, but still would like to understand what's going on.

  • How to get list of declared functions with their data from php file?

    - by ermac2014
    I need to get list of functions with their contents (not only the function name) from php file. I tried to use regex but it has lots of limitations. it doesn't parse all types of functions. for example it fails if the function has if and for loop statements. in details: I have around 100 include files. each file has number of declared functions. some files has functions duplicated in other files. so what I want is to get list of all functions from specific file then put this list inside an array then I will be using array unique in order to remove the duplicates. I read about tokenizer but I really have no idea how to make it grab the declared function with its data. all I have is this: function get_defined_functions_in_file($file) { $source = file_get_contents($file); $tokens = token_get_all($source); $functions = array(); $nextStringIsFunc = false; $inClass = false; $bracesCount = 0; foreach($tokens as $token) { switch($token[0]) { case T_CLASS: $inClass = true; break; case T_FUNCTION: if(!$inClass) $nextStringIsFunc = true; break; case T_STRING: if($nextStringIsFunc) { $nextStringIsFunc = false; $functions[] = $token[1]; } break; // Anonymous functions case '(': case ';': $nextStringIsFunc = false; break; // Exclude Classes case '{': if($inClass) $bracesCount++; break; case '}': if($inClass) { $bracesCount--; if($bracesCount === 0) $inClass = false; } break; } } return $functions; } unfortunately, this function lists only the function names.. what I need is to list the whole declared function with its structure.. so any ideas? thanks in advance..

  • php user authentication libraries / frameworks ... what are the options?

    - by es11
    I am using PHP and the codeigniter framework for a project I am working on, and require a user login/authentication system. For now I'd rather not use SSL (might be overkill and the fact that I am using shared hosting discourages this). I have considered using openID but decided that since my target audience is generally not technical, it might scare users away (not to mention that it requires mirroring of login information etc.). I know that I could write a hash based authentication (such as sha1) since there is no sensitive data being passed (I'd compare the level of sensitivity to that of stackoverflow). That being said, before making a custom solution, it would be nice to know if there are any good libraries or packages out there that you have used to provide semi-secure authentication? I am new to codeigniter, but something that integrates well with it would be preferable. Any ideas? (i'm open to criticism on my approach and open to suggestions as to why I might be crazy not to just use ssl). Thanks in advance. Update: I've looked into some of the suggestions. I am curious to try out zend-auth since it seems well supported and well built. Does anyone have experience with using zend-auth in codeigniter (is it too bulky?) and do you have a good reference on integrating it with CI? I do not need any complex authentication schemes..just a simple login/logout/password-management authorization system. Also, dx_auth seems interesting as well, however I am worried that it is too buggy. Has anybody else had success with this? I realized that I would also like to manage guest users (i.e. users that do not login/register) in a similar way to stackoverflow..so any suggestions that have this functionality would be great

  • How do I create JavaScript escape sequences in PHP?

    - by ordinarytoucan
    I'm looking for a way to create valid UTF-16 JavaScript escape sequence characters (including surrogate pairs) from within PHP. I'm using the code below to get the UTF-32 code points (from a UTF-8 encoded character). This works as JavaScript escape characters (eg. '\u00E1' for 'á') - until you get into the upper ranges where you get surrogate pairs (eg '??' comes out as '\u1D715' but should be '\uD835\uDF15')... function toOrdinal($chr) { if (ord($chr{0}) >= 0 && ord($chr{0}) <= 127) { return ord($chr{0}); } elseif (ord($chr{0}) >= 192 && ord($chr{0}) <= 223) { return (ord($chr{0}) - 192) * 64 + (ord($chr{1}) - 128); } elseif (ord($chr{0}) >= 224 && ord($chr{0}) <= 239) { return (ord($chr{0}) - 224) * 4096 + (ord($chr{1}) - 128) * 64 + (ord($chr{2}) - 128); } elseif (ord($chr{0}) >= 240 && ord($chr{0}) <= 247) { return (ord($chr{0}) - 240) * 262144 + (ord($chr{1}) - 128) * 4096 + (ord($chr{2}) - 128) * 64 + (ord($chr{3}) - 128); } elseif (ord($chr{0}) >= 248 && ord($chr{0}) <= 251) { return (ord($chr{0}) - 248) * 16777216 + (ord($chr{1}) - 128) * 262144 + (ord($chr{2}) - 128) * 4096 + (ord($chr{3}) - 128) * 64 + (ord($chr{4}) - 128); } elseif (ord($chr{0}) >= 252 && ord($chr{0}) <= 253) { return (ord($chr{0}) - 252) * 1073741824 + (ord($chr{1}) - 128) * 16777216 + (ord($chr{2}) - 128) * 262144 + (ord($chr{3}) - 128) * 4096 + (ord($chr{4}) - 128) * 64 + (ord($chr{5}) - 128); } } How do I adapt this code to give me proper UTF-16 code points? Thanks!

  • What's the difference between the input type "text" and "password" in an html form?

    - by Domingo
    Hi everybody, this question might seem stupid, but here's the situation: I'm trying to create an auto login page for my mail using jquery's post request, but it's not working, it works with all other pages except with webmail. So, trying to figure out what was wrong, I recreated the login form, here's the code: <form id="form1" name="form1" method="post" action="https://login.hostmonster.com/"> <label>User <input type="text" name="login" id="user" /> </label> <label>Pass <input name="password" type="password" id="pass" /> </label> <input name="doLogin" type="submit" id="doLogin" value="Login"> </form> The strange thing is when you change the input type of pass to text, the form doesn't work! I can't figure out why. Anyway, if you can tell me what's the real difference between the input type text and password (and not what it says everywhere on the net that the only difference is that when you type stars appear instead of characters) I would appreciate it. Also, do you think this is affecting my jquery's post? Here's the code for it: $j.post('https://login.hostmonster.com/', { login: '[email protected]', password: 'xxx' }, function(data, text){ if (text=='success') { alert('Success '+data); } else { alert('Failed'); } }); Thanks a lot!

  • Python: Is there a way to get HTML that was dynamically created by Javascript?

    - by Joschua
    As far as I can tell, this is the case for LyricWikia. The lyrics (example) can be accessed from the browser, but can't be found in the source code (can be opened with CTRL + U in most browsers) or reading the contents of the site with Python: from urllib.request import urlopen URL = 'http://lyrics.wikia.com/Billy_Joel:Piano_Man' r = urlopen(URL).read().decode('utf-8') And the test: >>> 'Now John at the bar is a friend of mine' in r False >>> 'John' in r False But when you select and look at the source code of the box in which the lyrics are displayed, you can see that there is: <div class="lyricbox">[...]</div> Is there a way to get the contents of that div-element with Python?

  • Can you have multiple clipping regions in an HTML Canvas?

    - by emh
    I have code that loads a bunch of images into hidden img elements and then a Javascript loop which places each image onto the canvas. However, I want to clip each image so that it is a circle when placed on the canvas. My loop looks like this: $$('#avatars img').each(function(avatar) { var canvas = $('canvas'); var context = canvas.getContext('2d'); var x = Math.floor(Math.random() * canvas.width); var y = Math.floor(Math.random() * canvas.height); context.beginPath(); context.arc(x+24, y+24, 20, 0, Math.PI * 2, 1); context.clip(); context.strokeStyle = "black"; context.drawImage(document.getElementById(avatar.id), x, y); context.stroke(); }); Problem is, only the first image is drawn (or is visible). If I remove the clipping logic: $$('#avatars img').each(function(avatar) { var canvas = $('canvas'); var context = canvas.getContext('2d'); var x = Math.floor(Math.random() * canvas.width); var y = Math.floor(Math.random() * canvas.height); context.drawImage(document.getElementById(avatar.id), x, y); }); Then all my images are drawn. Is there a way to get each image individually clipped? I tried resetting the clipping area to be the entire canvas between images but that didn't work.

  • Are there any libraries for showing diffs between two web pages?

    - by Chad Johnson
    I am looking for a library in any language--preferably PHP though--that will display the difference between two web pages. The differences can be displayed side-by-side, all in one document, or in any other creative way. Examples of what this would look like: http://1.bp.blogspot.com/_pLC3YDiv_I4/SBZPYQMDsPI/AAAAAAAAADk/wUMxK307jXw/s1600-h/wikipediadiff.jpg http://www.rohland.co.za/wp-content/uploads/2009/10/html_diff_output_text.PNG I am NOT looking for raw code diffing, like this: http://thinkingphp.org/img/code_coverage_html_diff_view.png. I do NOT want to show the difference between two sets of HTML. I want to show differences in rendered, WYSIWYG form. Every solution I tried suffered from one or more of the following problems: If I change the attribute of an element (eg. change [table border="1"] to [table border="2"]), then I'll have an extra table tag in the output (eg. [table border="1"][table border="1"][tr][td]...). And, one table tag will have a del tag around it, while the other will have an ins tag around it, and that will obviously cause problems. If I change [html][body][b]some content here[/b][/body][/html] to [html][body][i]some other content here[/i][/body][/html] then it looks like [html][body][b][del]original[/del][i][ins]new[/ins] content here[/b][/i][/body][/html] I'm looking for out-of-the-box ideas. Any ideas are welcome.

  • Copy a multi-dimentional array by Value (not by reference) in PHP.

    - by Simon R
    Language: PHP I have a form which asks users for their educational details, course details and technical details. When the form is submitted the page goes to a different page to run processes on the information and save parts to a database. HOWEVER(!) I then need to return the page back to the original page, where having access to the original post information is needed. I thought it would be simple to copy (by value) the multi-dimensional (md) $_POST array to $_SESSION['post'] session_start(); $_SESSION['post'] = $_POST; However this only appears to place the top level of the array into $_SESSION['post'] not doing anything with the children/sub-arrays. An abbreviated form of the md $_POST array is as follows: Array ( [formid] = 2 [edu] = Array ( ['id'] = Array ( [1] = new_1 [2] = new_2 ) ['nameOfInstitution'] = Array ( [1] = 1 [2] = 2 ) ['qualification'] = Array ( [1] = blah [2] = blah ) ['grade'] = Array ( [1] = blah [2] = blah ) ) [vID] = 61 [Submit] = Save and Continue ) If I echo $_SESSION['post']['formid'] it writes "2", and if I echo $_SESSION['post']['edu'] it returns "Array". If I check that edu is an array (is_array($_SESSION['post']['edu])) it returns true. If I echo $_SESSION['post']['edu']['id'] it returns array, but when checked (is_array($_SESSION['post']['edu]['id'])) it returns false and I cannot echo out any of the elements. How do I successfully copy (by value, not by reference) the whole array (including its children) to an new array?

  • how do I insert an hidden token in my form to prevent double posts? (PHP)

    - by jpjp
    I want to prevent users from accidentally posting a comment twice. I use the PRG (post redirect get) method, so that I insert the data on another page then redirect the user back to the page which shows the comment. This allows users to refresh as many times as they want. However this doesn't work when the user goes back and clicks submit again or when they click submit 100 times really fast. I don't want 100 of the same comments. I looked at related questions on SO and found that a token is best. But I am having trouble using it. //makerandomtoken(20) returns a random 20 length char. <form method="post" ... > <input type="text" id="comments" name="comments" class="commentbox" /><br/> <input type="hidden" name="_token" value="<?php echo $token=makerandomtoken(20); ?>" /> <input type="submit" value="submit" name="submit" /> </form> if (isset($_POST['submit']) && !empty($comments)) { $comments= mysqli_real_escape_string($dbc,trim($_POST['comments'])); //how do I make the if-statment to check if the token has been already set once? if ( ____________){ //don't insert comment because already clicked submit } else{ //insert the comment into the database } } So I have the token as a hidden value, but how do I use that to prevent multiple clicking of submit.
