• Parse error: syntax error, unexpected T_PUBLIC in ..... ?

  - by tonsils

  Hi, I am new to php and trying out this tutorial at : http://css-tricks.com/php-for-beginners-building-your-first-simple-cms/ Unfortunately I am getting the following error and can't seem to track down the reason: Parse error: syntax error, unexpected T_PUBLIC in ../simpleCMS.php on line 56 My code for simpleCMS.php is as is in the tutorial link above. FYI, my line 56 is the following line of code in simpleCMS.php public function display_admin() { Above this line is public function display_public() Can anyone possibly see what I could be doing wrong and again, my code is the same code from the tutorial website and have downloaded the files that came with it? Hoping someone can point me in the right direction. Furthermore, I am using Mac OS X MAMP to run my Apache/MySQL Server locally. My other question is, when I using the following command: mysql_connect($this->host,$this->username,$this->password) is my hostname 'localhost' alone or do I also have to include port alongside the localhost? Thanks again.

• Ruby Error: "No such file or directory -- script/generate (LoadError)"

  - by Jenius

  Hey all, I know that this error has been discussed elsewhere on the web, and this may seem like a stupid question, but I've got a very strange situation on my hands here. I'm running on Snow Leopard, with fully updated ruby and rails gems. I created a new rails project (ruby new testing), then navigated into that folder (cd ~/testing), and tried to create a basic scaffolding (ruby script/generate scaffold newtest name:string), and I got this error back: "ruby: No such file or directory -- script/generate (LoadError)" I have searched google thoroughly and tried to implement every solution that I could, but nothing has been working. I don't understand why I have this error or how to fix it. Can anyone help me, please?

• How do you diagnose a 500 error on Heroku when there is no error message in the logs?

  - by lala

  I have a Rails app on Heroku that is serving 500 errors at random intervals. Web pages will display "Internal server error" in plain text, instead of the usual "We're sorry. Something went wrong." page. When I refresh the page, it works fine. The logs don't show me an error message, just » 14:20:34.107 2013-10-11 12:20:33.763690+00:00 heroku router - - at=info method=HEAD path=/ host=www.mydomain.com fwd="184.73.237.85/ec2-184-73-237-85.compute-1.amazonaws.com" dyno=web.1 connect=1ms service=63ms status=200 bytes=0 » 14:21:03.957 2013-10-11 12:21:03.561867+00:00 heroku router - - at=info method=GET path=/ host=www.mydomain.com fwd="50.112.95.211/ec2-50-112-95-211.us-west-2.compute.amazonaws.com" dyno=web.1 connect=0ms service=1ms status=500 bytes=21 Support has told me to look at request queuing in New Relic, but New Relic only shows a big red mark saying the server is down (even though the site works fine when refreshed). With no error messages, I'm at a loss for how to diagnose this issue.

• Displaying custom error message for a blank field in a simple JSF application

  - by 29b5k

  Hi all, I was trying out a simple JSF application, in which I need to check if the "name" field is blank, then display an error message. The code which takes the field's value is: <h:outputLabel value="Name"></h:outputLabel> <h:inputText value="#{greeting.name}" required = "true"> <f:validator validatorId="NumValidator"></f:validator> </h:inputText> The control of the program does not go into the validator class, if the field is submitted without entering anything, and it displays the default error message: j_id_jsp_869892673_1:j_id_jsp_869892673_4: Validation Error: Value is required. How do i display a custom message for this ?

• MYSQL: Error: Cannot add or update a child row: a foreign key constraint fails

  - by DalivDali

  Hi all, Using MySQL on Windows OS, and am getting an error upon attempting to create a foreign key between two tables: CREATE TABLE tf_traffic_stats ( domain_name char(100) NOT NULL, session_count int(11) NULL, search_count int(11) NULL, click_count int(11) NULL, revenue float NULL, rpm float NULL, cpc float NULL, traffic_date date NOT NULL DEFAULT '0000-00-00', PRIMARY KEY(domain_name,traffic_date)) and CREATE TABLE td_domain_name ( domain_id int(10) UNSIGNED AUTO_INCREMENT NOT NULL, domain_name char(100) NOT NULL, update_date date NOT NULL, PRIMARY KEY(domain_id)) The following statement gives me the error present in the subject line (cannot add or update a child row: a foreign key constraint fails): ALTER TABLE td_domain_name ADD CONSTRAINT FK_domain_name FOREIGN KEY(domain_name) REFERENCES tf_traffic_stats(domain_name) ON DELETE RESTRICT ON UPDATE RESTRICT Can someone point me in the right direction of what may be causing the error. I also have a foreign key referencing td_domain_name.domain_id, but I don't think this should be interfering... Appreciate it!

• [BUG] Bus Error - What causes this in Ruby?

  - by viatropos

  I have run into this error 5 or 10 times over the past few years and have never found a clear answer to this problem. Here is the error: $ rake db:migrate /usr/lib/ruby/gems/1.8/gems/libxml-ruby-0.9.5/lib/libxml_ruby.bundle: [BUG] Bus Error ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin9.7.0] Abort trap The app I am running this in is using RMagick. I have run into this problem when installing ImageMagick a while ago, and when installing Nokogiri, and when installing MySQL. For Nokogiri it was because I needed a more recent version of libxml. What are your thoughts on this? Any fixes? How can I check the version of RMagick the project is loading? I am on a Mac, 10.5.8. Thanks for the help, Lance

• PhysX SDK - error LNK2019: unresolved external symbol when compiling "wavefront.cpp"

  Hi all, I'm using the PhysX SDK and I'm trying to load an .obj file with the WavefrontObj object which is defined by the files "wavefront.h/.cpp", localized in the samples directory.

• Graceful DOS Command Error-Handling w/PHP popen()

  - by Captain Obvious

  PHP 5.2.13 on Windows 2003 I am using the DOS Start /B command to launch a background application using the PHP popen() function: popen("start /B {$_SERVER['HOMEPATH']}/{$app}.exe > {$_SERVER['HOMEPATH']}/bg_output.log 2>&1 & echo $!", 'r'); The popen() function launches a cmd.exe process that runs the specified command; however, if the command fails (e.g. the {$app}.exe doesn't exist or is locked in the above example), the cmd.exe process never returns, and PHP hangs indefinitely as a result. Calling the failing DOS command directly using the Command Prompt results in an Error prompt that requires clicking the OK button. I assume this error confirmation requirement is what's preventing the cmd.exe process from returning to PHP both from the Command Prompt (using both CGI and CLI) and the web (using Apache 2.0 handler w/Apache 2.2). Is there a way to configure PHP, Apache, and/or Win 2003 to return the DOS error to the originating call rather than waiting for confirmation?

• C++ Operator overloading - 'recreating the Vector'

  - by Wallter

  I am currently in a collage second level programing course... We are working on operator overloading... to do this we are to rebuild the vector class... I was building the class and found that most of it is based on the [] operator.

• Error debugging - Conversion from String to Double

  - by Jamie Taylor

  I'm doing some error debugging trying to get the errors on our website down to a minimum and there seems to be an error that is popping up quite a lot Conversion from string "" to type 'Double' is not valid. I'm unable to replicate this problem but I can see that it is happening. I've been looking through the code in one of the pages and strolled across this Dim varWeek As String If varWeek < 10 Then 'Do something' End If Could this be causing the problem as it is trying to see if a String is less than 10 which is an Integer? As I said before as I am unable to see this error in the first place so changing this to an Integer doesn't change anything on my system. Thanks.

• Asp.Net : IHttpModule + m_context.Server.Transfer = session state error

  - by tinky05

  I have an IHttpModule that implements IRequiresSessionState. The session state is at "on" on the page directive and I also added it to the web.config. In the method "OnBeginRequest" in the IHttpModule, I make a Server.Transfer but I get the error : Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. When I access the page directly or with a Response.Redirect, there is no error. Any idea? Update : The error occur in a page extending System.Web.UI.Page in the method InitializeCulture() which is an override.

• Change the text of a gcc compiler error

  - by NSA

  Hello, At my company we have recently done some tricky stuff with C++ and templates, making use of some features of the compiler. When working with this code people need to take a few setup steps otherwise they get some rather cryptic compiler errors, what I would like to do is determine if there is a way to tell the compiler to inject, and or swap out the message published for an error when compiling? so that I either get a friendly message that instructs the person in conjunction with the cryptic error or instead of the cryptic error. Thank you.
