  • Should one use PHP to print all of a page's HTML?

    - by Mala
    Hi So I've always developed PHP pages like this: <?php goes at the top, ?> goes at the bottom, and all the HTML gets either print()ed or echo()ed out. Is that slower than having non-dynamic html outputted outside of <?php ?> tags? I can't seem to find any info about this. Thanks! --Mala UPDATE: the consesus seems to be on doing it my old way being hard to read. This is not the case if you break your strings up line by line as in: print("\n". "first line goes here\n". "second line goes here\n". "third line"); etc. It actually makes it a lot easier to read than having html outside of php structures, as this way everything is properly indented. That being said, it involves a lot of string concatenation.

  • How to perform COUNT() or COUNT(*)

    - by ninumedia
    I have a list of tags in a database. Ex: villan hero spiderman superman superman I wanted to obtain a sorted list of the tag names in ascending order and the number of times the unique tag appeared in the database. I wrote this code: Ex: SELECT hashtag.tag_name, COUNT( * ) AS number FROM hashtag GROUP BY hashtag.tag_name ORDER BY hashtag.tag_name ASC This yields the correct result: hero - 1 spiderman - 1 superman - 2 villan - 1 How can I obtain the full COUNT of this entire list. The answer should be 4 in this case because there are naturally 4 rows. I can't seem to get a correct COUNT() without the statement failing. Thanks so much for the help! :)

  • How to select DISTINCT rows without having the ORDER BY field selected

    - by JannieT
    So I have two tables students (PK sID) and mentors (PK pID). This query SELECT s.pID FROM students s JOIN mentors m ON s.pID = m.pID WHERE m.tags LIKE '%a%' ORDER BY s.sID DESC; delivers this result pID ------------- 9 9 3 9 3 9 9 9 10 9 3 10 etc... I am trying to get a list of distinct mentor ID's with this ordering so I am looking for the SQL to produce pID ------------- 9 3 10 If I simply insert a DISTINCT in the SELECT clause I get an unexpected result of 10, 9, 3 (wrong order). Any help much appreciated.

  • etree.findall: 'OR'-lookup?

    - by piquadrat
    I want to find all stylesheet definitions in a XHTML file with lxml.etree.findall. This could be as simple as elems = tree.findall('link[@rel="stylesheet"]') + tree.findall('style') But the problem with CSS style definitions is that the order matters, e.g. <link rel="stylesheet" type="text/css" href="/media/css/first.css" /> <style>body:{font-size: 10px;}</style> <link rel="stylesheet" type="text/css" href="/media/css/second.css" /> if the contents of the style tag is applied after the rules in the two link tags, the result may be completely different from the one where the rules are applied in order of definition. So, how would I do a lookup that inlcudes both link[@rel="stylesheet"] and style?

  • Struts 2 how to display messages saved in a Interceptor which would redirec to another action?

    - by mui13
    in my interceptor, if user doesn't have enough right, there would be a warn message: public String intercept(ActionInvocation invocation) throws Exception { ActionContext actionContext = invocation.getInvocationContext(); Map<String, Object> sessionMap = actionContext.getSession(); User loginUser = (User) sessionMap.get("user"); Object action = invocation.getAction(); if (loginUser != null && loginUser.getRole().getId() != Constant.AUTHORITY_ADMIN) { ((ValidationAware) action).addFieldError("user.authority", ((DefaultAction) action).getText("user.action.authority.not.enough")); return DefaultAction.HOME_PAGE; } return invocation.invoke(); } then, it would redirect to "HOME_PAGE" action, if success, display information in the jsp. So how to display the warn message? i have used two interceptors configed in strust.xml, for admin right requirment: <interceptor-stack name="authorityStack"> <interceptor-ref name="authority" /> <interceptor-ref name="defaultStack" /> <interceptor-ref name="store"> <param name="operationMode">STORE</param> </interceptor-ref> </interceptor-stack> default is: <interceptor-stack name="default"> <interceptor-ref name="login" /> <interceptor-ref name="defaultStack" /> <interceptor-ref name="store"> <param name="operationMode">AUTOMATIC</param> </interceptor-ref> </interceptor-stack>

  • how to check whether some entered InnerText is present in an XML or not and to give an exception?

    - by Damodar
    Hey all, I have written a code in C# - XML which checks whether a value is there or not in a given XML document and prints the value and the particular tag associated with the value. When we enter the Value of the Inner Text it will look for the value in the document and find it. I dont understand what exception to catch when the entered value is not there in the document. I tried doing like this but it is not working. 1. if (inpXMLString != AppChildNode.InnerText) throw new InvalidDataException("The entered value" + " " + inpXMLString + " " + "doesnot exist"); Here : inpXMLstring = entered value; AppChildNode.InnerText = value of the tags searched. 2. catch (System.Xml.XmlException e1) { Console.WriteLine(e1.Message); } this does not give any exception when the entered value is not there in the XML document. Please help me in this regard.

  • How to send argument securely using Process class?

    - by Sebastian
    Hello, I'm using System.Diagnostics.Process to execute an svn command from a windows console application. This is the configuration of the process: svn.StartInfo.FileName = svnPath; svn.StartInfo.Arguments = string.Format("copy {0}/trunk/ {0}/tags/{1} -r head -q --username {3} --password {4} -m \"{2}\"", basePathToRepo, tagName, message, svnUserName, svnPassword); svn.StartInfo.UseShellExecute = false; svn.Start(); svn.WaitForExit(); My problem is that those arguments, which include the svn credentials, are sent (I suppose) in an unsecure way. Is there a way to send these arguments in a secure way using the Process class? Thanks!

  • Using struts.xml with convention plugin

    - by David Alt
    This seems like it should be easy to do, but I just can make it work. I'm hooked on the convention plugin in Struts 2.1. However, I need to define some package-level configuration such as a new interceptor stack and exception mappings. I'd like to use the struts.xml file for this, but I can't get the convention-based packages matched to the struts.xml packages. My struts.xml looks like: <struts> <constant name="struts.convention.default.parent.package" value="default"/> <package name="default" extends="struts-default"> </package> <package name="root" namespace="/" extends="struts-default"> <action name="index"> <result>/index.jsp</result> </action> </package> <package name="my.package.actions.myaccount" namespace="/myaccount" extends="struts-default"> <interceptors> <interceptor name="authenticationInterceptor" class="my.package.interceptors.AuthenticationInterceptor"/> <interceptor-stack name="secureStack"> <interceptor-ref name="authenticationInterceptor"/> <interceptor-ref name="defaultStack"/> </interceptor-stack> </interceptors> <default-interceptor-ref name="secureStack"/> </package> </struts> I have my interceptor in: /src/my/package/interceptors and my actions in: /src/my/package/actions/myaccount

  • How to remove one instance of one string in PHP?

    - by Jane
    I have a open source editor on the cms that I am making that automatically inserts a <br /> tag at the beginning of the post it submits to the database. This makes validation a pain, since even though there is no real text being submitted, the form still accepts the break tag as input and prevents the "Please enter some text" error from showing. So I tried to remove the opening break tag by filtering my input like this: substr($_POST['content'], 6); This works as long as the user doesn't press the backspace a couple of times which removes the break tag in which case the first 8 characters of the post gets removed even if they are not a break tag. So how can I remove the first 6 characters of the input ONLY if those first 6 characters are composed of the break tag. Also I don't want to remove all break tags, only the one at the very beginning of the post.

  • Implementing tagging in JDO

    I am implementing a tagging system for a website that uses JDO . I would like to use this method. However I am new to relationships in JDO. To keep it simple, what I have looks like this: @PersistentCapable class Post { @Persistent String title; @Persistent String body; } @PersistentCapable class Tag { @Persistent String name; } What kind of JDO relationships do I need and how to implement them? I want to be able to list all Tags that belong to a Post, and also be able to list all Posts that have a given Tag.

  • HTML5 offline video caching in mobile safari

    - by jj
    Sorry if this gets posted twice, but Safari crashed while posting the first version, and I don't see it in my profile. Anyway I can't seem to get Safari on the iPhone or iPad to offline cache videos. Everything else gets cached just fine when I go offline. The video file is obviously in the manifest, but I just get the broken arrow. Works fine in Safari desktop. Any clues? I've tried both object embed and the video tags.

  • Check for a unique value within a count, but get all results

    - by pedalpete
    I'm trying to create a single query which, similar to stack overflow, will give me the number of votes, but also make sure that the currently viewing user can't upvote again if they've already upvoted. my query currently looks like SELECT cid, text, COUNT(votes.parentid) FROM comments LEFT JOIN votes ON comments.cid=votes.parentid AND votes.type=3 WHERE comments.type=0 AND comments.parentid='$commentParentid' GROUP BY comments.cid But I'm completely stumpted on how to add the check to see if the userid is in the votes table. The other option is to add a seperate query where SELECT COUNT(*) FROM votes WHERE userid='$userid' AND parentid='$commentParentid' AND type=3 I'm just realizing I'm so lost with this that I don't even really know what tags to provide.

  • Career Choice in JEE, are EJBs standard?

    - by John Baker
    I have chosen to go the JEE route for a career path but I have been having a hard time determining which core technologies that I need to be most familiar with. I'm at the point I can write web apps without a problem with JSP's and regular servlets using JDBC or some basic Hibernate stuff (I know, HTML, CSS and have used MVC extensively on a number of different platforms). What I'm trying to find out is if there is some standard as far as J2EE technologies go. When I look at most of the Job listings, occasionally you will see someone mention Struts or Spring but rarely do I see any mention of EJB's. So my question is really, are EJB's basically required by most JEE employers? Or are most of them working with POJO's? Is it a mix? I have a hard time figuring out if I should put the majority of my time into Struts, Spring/Hibernate, EJB's, etc. And if I do need to master EJB's what version should I learn? 2.1 or 3.0. 3.0 has some obviously better features but I figure a lot of companies probably chose to write their apps in 2.1 just because it was the standard of the time and now migrating would be a big deal. Any advice on this is greatly appreciated.

  • Action property of interface type

    - by Daniel
    Hi, guys. With my understading, the nature of a Action is that properties can be pushed w/ request parameter values. And, one wonderful feature is that Struts2 allows you to directly populate parameter values against Class type property ;) Assuming there exists a Action and property class as below, class Action extends ActionSupport { User user; @Action(value="hello" {@result=(.......)}) public void execute() { ........ } ..... public void setUser(User user) { this.user = user; } public User getUser() { return this.user; } } class User { String name; ..... public void setName(String name) { this.name = name; } public String getName() { return this.name; } } you could populate User class property by doing like this. http://...../hello.action?user.name=John or via jsp page Then, I realize that there are actually people make an Action property as a Interface type. My question is what is the reason behind this. If there is a sample code demonstrating it will be great. Thanks in advance!

  • Best library to parse HTML with Python 3 and example?

    - by TMC
    I'm new to Python completely and am using Python 3.1 on Windows (pywin). I need to parse some HTML, to essentially extra values between specific HTML tags and am confused at my array of options, and everything I find is suited for Python 2.x. I've read raves about Beautiful Soup, HTML5Lib and lxml, but I cannot figure out how to install any of these on Windows. Questions: What HTML parser do you recommend? How do I install it? Do you have a simple example on how to use the recommended library to snag HTML from a specific URL and return the value out of say something like this: fooLink (say we want to return "/blahblah")

  • Why is nodeName sometimes all-caps in javascript DOM?

    - by harpo
    So I have a DOM document that looks essentially like this <categories> <category id="1"/> <category id="2"/> </categories> This is how the document previews in Firebug, as I would expect. However, when I POST this to the server, I get <categories> <CATEGORY id="1"/> <CATEGORY id="2"/> </categories> Indeed, doc.documentElement.firstChild.nodeName returns "CATEGORY". The nodes are added using jQuery.append('<category/>'). Why are the child tags returned in all caps?

  • Regular Expression find a phrase not inside an HTML tag

    - by James Buckingham
    Hi there, I'm struggling a bit with this regular expression and wondered if anyone was about to help me please? What I need to do is isolate the 1st phrase inside a string which is NOT inside an HTML tag. So the examples I have at the moment are: This is some test text about ITS for the ITS department. Also worth mentioning ABS as well I guess.ITS, ... and ... This is some ITS test text about ITS for the ITS department. Also worth mentioning ABS as well I guess So in the first example I want it to ignore the wrapped ITS and give me the ITS at the end of the 1st sentence. In the second example I want it to return the ITS at the start of the 2nd sentence. The aim is to replace these with my own custom wrapped acronym tags in a ColdFusion application I'm writing. Thanks a lot, James

  • Construct a LPCWSTR on WinCE in C++ (Zune/ZDK)

    - by James Cadd
    What's a good way to construct an LPCWSTR on WinCE 6? I'd like to find something similar to String.Format() in C#. My attempt is: OSVERSIONINFO vi; memset (&vi, 0, sizeof vi); vi.dwOSVersionInfoSize = sizeof vi; GetVersionEx (&vi); char buffer[50]; int n = sprintf(buffer, "The OS version is: %d.%d", vi.dwMajorVersion, vi.dwMinorVersion); ZDKSystem_ShowMessageBox(buffer, MESSAGEBOX_TYPE_OK); That ZDKSystem_ShowMessageBox refers to the ZDK for hacked Zunes available at: http://zunedevwiki.org This line of code works well with the message box call: ZDKSystem_ShowMessageBox(L"Hello Zune", MESSAGEBOX_TYPE_OK); My basic goal is to look at the exact version of WinCE running on a Zune HD to see which features are available (i.e. is it R2 or earlier?). Also I haven't seen any tags for the ZDK so please edit if something is more fitting!
