  • Porting some PHP to ColdFusion

    - by Oscar Godson
    OK, I'm working with converting some very basic PHP to port to a dev server where the client only has CF. Ive never worked with it, and I just need to know how to port a couple things: <?php $pageTitle = 'The City That Works'; $mainCSSURL = 'header_url=../images/banner-home.jpg&amp;second_color=484848&amp;primary_color=333&amp;link_color=09c&amp;sidebar_color=f2f2f2'; require('includes/header-inc.php'); ?> I know: <cfinclude template="includes/header-inc.cfm"> but how to i get the var to be passed to the include and then how do I use it on the subsequent included file? Also in my CSS (main.php) I have (at the top): <?php header('Content-type: text/css'); foreach($_GET as $css_property => $css_value) {define(strtoupper($css_property),$css_value);} ?> and im using those constants like this: #main-content a {color:#<?= LINK_COLOR ?>;} How can I get that to work also with CF? Never thought I'd be working with CF :)

  • PHP include by name

    - by Adrian M.
    Hello, I have "content" folder which is full of other sub-directories named in the following way: "id1_1","id1_2", "id1_3" and other "id2_1", "id2_2" etc. Each of these folders contains a file "template.php", same name in all sub-directories. The number of folders is dynamic so I need to find a way to import in "index.php" only the "template.php" from all the folders starting with "id_1_". How can I do it? Thanks!

  • Intermittent "No Database Selected" in PHP/MySQL?

    - by ANE
    Have a PHP/MySQL form with a dropdown box containing a list of 350 names. When any random name is selected, sometimes it works & displays info about that name from the database, and sometimes the form gives the error "No Database Selected". Here's what I've tried, pretty much grasping at straws as I'm not a programmer: Increasing max_connections in /etc/my.cnf from 200 to 2000 (even though only 4-5 connections are made and it's a lightly used server) Changing mysql_pconnect to mysql_connect Adding the word true to this connection string: $mysql = mysql_pconnect($hostname_mysql, $username_mysql, $password_mysql, true) or trigger_error(mysql_error(),E_USER_ERROR); Changing the word require_once to require on this line: [?php require('/home/user/Connections/mysql.php'); ?] Enabling MySQL & PHP query & error logging. (no errors logged) Here is the code: [removed old bad code] Update: Working answer from Rob Apodaca below.

  • Calling Excel from PHP 5 through COM fails on Windows 7 when Apache started through Task Planner

    - by Stefan Pantke
    I currently write an application, which controls Excel through COM: The app creates a COM-based Excel instance, opens some XLS files and reads their contents. Scenario I On Windows 7, I start Apache and mySQL using xmapp-control with system administrator rights. All works as expected. The PHP-based controller script interacts with Excel as expected. Scenario II A problem appears, if I start Apache and mySQL as 'background jobs'. Here is how: I created two jobs using Windows 7 Task Planner. One runs apache_start.bat, the other runs mysql_start.bat. Both tasks run as SYSTEM with elevated privileges when Windows 7 boots. Apache and mySQL work as expected. Specifically, Apache serves HTTP request from clients and PHP is able to talk to mySQL. When I call the PHP controller, which calls and interacts with Excel using COM, I do receive an error. The error seems to come from Excel [not COM itself] and reads like this: Excel can't read the XLS-file Excel failed to save the file due to an ill-name worksheet Interestingly, during the first run of the PHP-based controller script, it takes a few seconds to render the error message. Each subsequent run immediately renders the error message. Windows system logs didn't show a single problem report entry. Note, that the PHP program and the Apache instance didn't change - except the way Apache was started. At least the PHP controller script is perfectly able to read the file-system, since it provides the pathes to the XLS-file through scandir() of a certain directory. Concurrency issues can't be the cause of the problem. A single instance of the specific PHP controller interacts with Excel. Question Could someone provide details, why this happens?

  • Using a string inside the DocumentBuilder parse method (need it for parsing XML using XPath)

    - by dierre
    Hi guys! I'm trying to create a RESTful webservice using a Java Servlet. The problem is I have to pass via POST method to a webserver a request. The content of this request is not a parameter but the body itself. So I basically send from ruby something like this: url = URI.parse(@host) req = Net::HTTP::Post.new('/WebService/WebServiceServlet') req['Content-Type'] = "text/xml" # req.basic_auth 'account', 'password' req.body = data response = Net::HTTP.start(url.host, url.port){ |http| puts http.request(req).body } Then I have to retrieve the body of this request in my servlet. I use the classic readline, so I have a string. The problem is when I have to parse it as XML: private void useXML( final String soft, final PrintWriter out) throws ParserConfigurationException, SAXException, IOException, XPathExpressionException, FileNotFoundException { DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance(); domFactory.setNamespaceAware(true); // never forget this! DocumentBuilder builder = domFactory.newDocumentBuilder(); Document doc = builder.parse(soft); XPathFactory factory = XPathFactory.newInstance(); XPath xpath = factory.newXPath(); XPathExpression expr = xpath.compile("//software/text()"); Object result = expr.evaluate(doc, XPathConstants.NODESET); NodeList nodes = (NodeList) result; for (int i = 0; i < nodes.getLength(); i++) { out.println(nodes.item(i).getNodeValue()); } } The problem is that builder.parse() accepts: parse(File f), parse(InputSource is), parse(InputStream is). Is there any way I can transform my xml string in an InputSource or something like that? I know it could be a dummy question but Java is not my thing, I'm forced to use it and I'm not very skilled.

  • Segmentation fault when accessing a PHP page

    - by Justin Ethier
    Sometimes when one of our Apache web servers is restarted, we experience segmentation faults when any PHP page is subsequently accessed. The following line is printed in the httpd error_log: [Wed Jun 16 10:59:33 2010] [notice] child pid 31513 exit signal Segmentation fault (11) There will be one of these lines for each PHP page that is accessed. This appears to happen randomly - the "workaround" to-date is to restart httpd, which eventually fixes the problem (almost always after a single restart). Although we only see this happen rarely, it still happens frequently enough to be of concern. So my question is, why is this happening in the first place? Is this a known bug with the version of Apache / PHP / Linux / etc that we are using? Any ideas? The environment is: Fedora 11 Apache 2.2.15 (Default settings) PHP 5.2.13 I can provide more information if that would help narrow things down, since this error message is rather generic... Any help is appreciated.

  • Extremely basic PHP and Mysql

    - by fighella
    Background: I am more of a designer than a programmer, but have hacked templates for many open source CMS's (Drupal, Joomla, Wordpress) I want to start from scratch in regards to the relations of php and a mysql database. Lets assume I have a working database and php engine locally. What would be my first step to connecting to my database and creating a table... (im happy to be led to an appropriate tutorial...) Many of the tutorials I have seen start with basic php, but I would rather explore the connection between the db and the php.

  • XML-RPC over SSL with Ruby: end of file reached (EOFError)

    - by Michael Conigliaro
    Hello, I have some very simple Ruby code that is attempting to do XML-RPC over SSL: require 'xmlrpc/client' require 'pp' server = XMLRPC::Client.new2("https://%s:%d/" % [ 'api.ultradns.net', 8755 ]) pp server.call2('UDNS_OpenConnection', 'sponsor', 'username', 'password') The problem is that it always results in the following EOFError exception: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/protocol.rb:135:in `sysread': end of file reached (EOFError) So it appears that after doing the POST, I don't get anything back. Interestingly, this is the behavior I would expect if I tried to make an HTTP connection on the HTTPS port (or visa versa), and I actually do get the same exact exception if I change the protocol. Everything I've looked at indicates that using "https://" in the URL is enough to enable SSL, but I'm starting wonder if I've missed something. Note that Even though the credentials I'm using in the RPC are made up, I'm expecting to at least get back an XML error page (similar to if you access https://api.ultradns.net:8755/ with a web browser). I've tried running this code on OSX and Linux with the exact same result, so I have to conclude that I'm just doing something wrong here. Does anyone have any examples of doing XML-RPC over SSL with Ruby?

  • Choose a XML node in SQL Server based on max value of a child element

    - by Jay
    I am trying to select from SQL Server 2005 XML datatype some values based on the max data that is located in a child node. I have multiple rows with XML similar to the following stored in a field in SQL Server: <user> <name>Joe</name> <token> <id>ABC123</id> <endDate>2013-06-16 18:48:50.111</endDate> </token> <token> <id>XYX456</id> <endDate>2014-01-01 18:48:50.111</endDate> </token> </user> I want to perform a select from this XML column where it determines the max date within the token element and would return the datarows similar to the result below for each record: Joe XYZ456 2014-01-01 18:48:50.111 I have tried to find a max function for xpath that would all me to select the correct token element but I couldn't find one that would work. I also tried to use the SQL MAX function but I wasn't able to get it working with that method either. If I only have a single token it of course works fine but when I have more than one I get a NULL, most likely because the query doesn't know which date to pull. I was hoping there would be a way to specify a where clause [max(endDate)] on the token element but haven't found a way to do that. Here is an example of the one that works when I only have a single token: SELECT XMLCOL.query('user/name').value('.','NVARCHAR(20)') as name XMLCOL.query('user/token/id').value('.','NVARCHAR(20)') as id XMLCOL.query('user/token/endDate').value(,'xs:datetime(.)','DATETIME') as endDate FROM MYTABLE

  • PHP specifying a fixed include source for scripts in different directories

    - by Extrakun
    I am currently doing unit testing, and use folders to organize my test cases. All cases pertaining to managing of user accounts, for example, go under \tests\accounts. Over time, there are more test cases, and I begin to seperate the cases by types, such as \tests\accounts\create, \tests\account\update and etc. However, one annoying problem is I have to specify the path to a set of common includes. I have to use includes like this: include_once ("../../../../autoload.php"); include_once ("../../../../init.php"); A test case in tests\accounts\ would require change to the include (one less directory level down). Is there anyway to have them somehow locating my two common includes? I understand I could set include paths within my PHP's configurations, or use server environment variables, but I would like to avoid such solutions as they make the application less portable and coupled with another layer which the programmer can't control (some web-host doesn't allow configuration of PHP's configuration settings, for example)

  • Android - Loop Through strings.xml file

    - by Alexis Cartier
    I was wondering if there is anyway to loop through the strings.xml file. Let's say that I have the following format: <!-- FIRST SECTION --> <string name="change_password">Change Password</string> <string name="change_server">Change URL</string> <string name="default_password">password</string> <string name="default_server">http://xxx:8080</string> <string name="default_username">testPhoneAccount</string> <!-- SECOND SECTION --> <string name="debug_settings_category">Debug Settings</string> <string name="reload_data_every_startup_pref">reload_data_every_startup</string> <string name="reload_data_on_first_startup_pref">reload_data_on_first_startup</string> Now let's say I have this: private HashMap<String,Integer> hashmapStringValues = new HashMap<String, Integer>(); Is there a way to iterate only in the second section of my xml file? Maybe wrap the section with a tag like <section2> and then iterate through it? public void initHashMap(){ for (int i=0;i< ???? ;i++) //Here I need to loop only in the second section of my xml file { String nameOfTag = ? // Here I get the name of the tag int value = R.string.nameOfTag // Here I get the associated value of the tag this.hashmapStringValues.put(nameOfTag,value); } }

  • php simplexmlelement get first element in one line

    - by Senica Gonzalez
    Just trying to figure a shorter way to do this: I'm using simpleXMLElement to parse an xml file and it's aggravating to have to call two lines to process an array when I know what node I want. Current code: $xml = new SimpleXMLElement($data); $r = $xml->xpath('///givexNumber'); $result["cardNum"] = $r[0]; What I would like to do would be something like I can do with DomX $result["cardNum"] = $xml->xpath('///givexNumber')->item(0)->nodeValue; Any ideas? I didn't really see that simplexmlelement can do this, but thought someone might know a trick or two.

  • Duplicate elements when adding XElement to XDocument

    - by Andy
    I'm writing a program in C# that will go through a bunch of config.xml files and update certain elements, or add them if they don't exist. I have the portion down that updates an element if it exists with this code: XDocument xdoc = XDocument.Parse(ReadFile(_file)); XElement element = xdoc.Elements("project").Elements("logRotator") .Elements("daysToKeep").Single(); element.Value = _DoRevert; But I'm running into issues when I want to add an element that doesn't exist. Most of the time part of the tree is in place and when I use my code it adds another identical tree, and that causes the program reading the xml to blow up. here is how I am attempting to do it xdoc.Element("project").Add(new XElement("logRotator", new XElement("daysToKeep", _day))); and that results in a structure like this(The numToKeep tag was already there): <project> <logRotator> <daysToKeep>10</daysToKeep> </logRotator> <logRotator> <numToKeep>13</numToKeep> </logRotator> </project> but this is what I want <project> <logRotator> <daysToKeep>10</daysToKeep> <numToKeep>13</numToKeep> </logRotator> </project>

  • Newsletter send using AJAX to avoid PHP timeout

    - by simPod
    I need to send newsletters. I have already a PHP script that sends mass emails but it won't work for long as email database is growing because of PHP max script run time. So, to avoid it I came up with a solution: I would call my PHP script using AJAX in javascript and I will give it $_GET parameter with a count 20 so the script would sent only 20 emails. Than AJAX would receive success response, and call my script again and again till all emails are send. Is it possible? I'm asking because I have never seen such a solution so I'm wondering if it is real (It's kinda hard to implement this into my PHP framework so I'm asking experts here first) To sum it up here's a code skeleton: <script> var emailCount = 1000; //would get this from DB var runCount = 20; //number of emails sent in one cycle var from = 0; //start number function sendMail(){ if(from<emailCount){ jQuery.ajaxfunction({ path: 'script.php?from='+from+'&count='+runCount successFc: function(){ from+=runCount; sendMail(); } }) } } sendMail(); </script> So, are there any obstacles? Thanks a lot.

  • Write permissions on uploaded files - Linux, Apache, PHP

    - by letseatfood
    I am working on a PHP script that transfers files using FTP functions. It has always worked on my production server (which is a hosting service). The development server I have just setup (I am a novice to servers) is Debian Lenny with Apache2, PHP5, and MySQL5. The file transfer works correctly, but once the file has been written to the server, it has permissions of 600. This makes it impossible for me to view the file (JPEG) in the web browser, as permission is denied. I have scoured the internet and even broken my server installation and reinstalled it trying to figure this out (which has been fun, nonetheless!). I know it is unwise to set 777 permissions on public accessible files, but even that will not solve the problem. The only thing that works is if I chmod 777 thefile.jpg after it has been transferred, which is not a working solution. I tried changing the owner of my site files to www-data per this post, but that also does not work. My user is mike, and it still does not work whether the owner of the files is mike or root. Would somebody point me in the right direction? Thanks! And, of course, let me know if I can clarify anything.

  • File based caching under PHP

    - by azatoth
    I've been using http://code.google.com/p/phpbrowscap/ for a project, and it usually works nice. But a few times it's cache, which is plain php-files (see http://code.google.com/p/phpbrowscap/source/browse/trunk/browscap/Browscap.php#372 et. al.), has been "zeroed", i.e. the whole cache file has become large blob of NULLs. Instead of trying to find out why the files become NULL, I though perhaps it might be better to change the caching strategy to something more resilient. So I do wonder if you has any good ideas what would be a good solution; I've been looking at http://www.jongales.com/blog/2009/02/18/simple-file-based-php-cache-class/ and http://www.phpclasses.org/package/313-PHP-Cache-arbitrary-data-in-files-.html and I also though of just saving an serialized array to the file instead of pure php as it's been doing now; But I'm uncertain what approach I should target here. I'm grateful for any insight into this area of technology, as I know it's complex from a performance point of view.

  • Downloading a file from a PHP page in C#

    - by FoxyShadoww
    Okay, we have a PHP script that creates an download link from a file and we want to download that file via C#. This works fine with progress etc but when the PHP page gives an error the program downloads the error page and saves it as the requested file. Here is the code we have atm: PHP Code: <?php $path = 'upload/test.rar'; if (file_exists($path)) { $mm_type="application/octet-stream"; header("Pragma: public"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Cache-Control: public"); header("Content-Description: File Transfer"); header("Content-Type: " . $mm_type); header("Content-Length: " .(string)(filesize($path)) ); header('Content-Disposition: attachment; filename="'.basename($path).'"'); header("Content-Transfer-Encoding: binary\n"); readfile($path); exit(); } else { print 'Sorry, we could not find requested download file.'; } ?> C# Code: private void btnDownload_Click(object sender, EventArgs e) { string url = "http://***.com/download.php"; WebClient client = new WebClient(); client.DownloadFileCompleted += new AsyncCompletedEventHandler(client_DownloadFileCompleted); client.DownloadProgressChanged += new DownloadProgressChangedEventHandler(ProgressChanged); client.DownloadFileAsync(new Uri(url), @"c:\temp\test.rar"); } private void ProgressChanged(object sender, DownloadProgressChangedEventArgs e) { progressBar.Value = e.ProgressPercentage; } void client_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e) { MessageBox.Show(print); }
