  • Foolproof way to check for nonzero (error) return code in windows batch file

    - by Pat
    Intro There's a lot of advice out there for dealing with return codes in batch files (using the ERROLEVEL mechanism), e.g. Get error code from within a batch file ERRORLEVEL inside IF Some of the advice is to do if errorlevel 1 goto somethingbad, while others recommend using the %ERRORLEVEL% variable and using ==, EQU, LSS, etc. There seem to be issues within IF statements and such, so then delayedexpansion is encouraged, but it seems to come with quirks of its own. Question What is a foolproof (i.e. robust, so it will work on nearly any system with nearly any return code) way to know if a bad (nonzero) code has been returned? My attempt For basic usage, the following seems to work ok to catch any nonzero return code: if not errorlevel 0 ( echo error level was nonzero )

  • Add links to specific words within span tag in PHP

    - by dazhall
    I have a list of words that I'd like to add a link to, I can do this fairly easily using preg_match_all and preg_replace: $str = "<span class=\"cz\">Dám si jedno pivo prosím.</span> = I'll have a beer please."; preg_match_all('/[a-ztúuýžácdéeínórš]+/i',$str,$matches); $matches = array_unique($matches[0]); foreach ($matches as $match) { if(!empty($words[$match])) { $str = preg_replace("/(^|[^\w]){1}(".preg_quote($match,"/").")($|[^\w]){1}/i", '\\1<a href="#">\\2</a>\\3', $str); } } echo $str; What I'd like to do is restrict the linking to only within the span tag. My brain is all regex-ed out, so any help would be appreciated! Thanks! Darren.

  • Bash Scripting: I want to open a set of .php files, and add line before html tag

    - by Bashn00b
    Hi guys, I have a set of .php files in a folder, I want to add text just before these lines: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" > What i want is to insert just before these lines in the html file. So just want to prepend that file before each docType declaration. However the DOCTYPE declaration is never on line 1, as there is loads of php lines before. I have this current script (where FE is the folder containing all the scripts i want to edit): for file in ${fe}*; do echo "$file" done Thanks,

  • Populate FILE field with default text

    - by dclowd9901
    I'm trying to reutilize code that generates FILE fields for use when something is to be added to the database, and grayed out (and disabled) with data already in the database when the item in question is being edited or viewed in detail. However, I can't seem to get the text to fill the field. I'm using this: echo '<input type="file" name="small[]" value="' . $value_from_database . '" DISABLED><br>'; Am I missing anything? If not, are there any decent workarounds?

  • Re-execute target when specified as dependency to multiple rules

    - by andrew
    I have the following GNU makefile: .PHONY a b c d a: b c b: d c: d d: echo HI I would like the target 'd' to be run twice -- since it is specified as a dependency by both b & c. Unfortunately, the target 'd' will be executed only once. The output of running make will simply be 'HI', instead of 'HI HI'. How can I fix this? Thanks! To Clarify, the goal is something like this: subdirs = a b c build: x y x: target=build x: $(subdirs) y: target=prepare y: $(subdirs) $(subdirs): $(make) -f $@/makefile $(target)

  • PHP eval() code in between <?php ?> from database

    - by kr1zmo
    Some of you may be annoyed with this question, and claim it's unsafe blah blah. I want to be able to put php into the database and run it. I have to do this because I store page layouts in the database and each our different for each other, however in some cases I want to use dynamic content for some of the pages. assume $query_from_db is the string returned from the database. php should only eval() the code in between <?php and ?> $query_from_db = '<div> <?php //php to run function dosomething() { //bleh } ?> </div> '; php echo eval($query_from_db);

  • modx revo snippet variable in query

    - by Meddie
    I noticed something weird when using a query in a snippet. When I have a query like this: $sql = 'SELECT * FROM table WHERE colomn = ' . $variable; And I echo $sql, the query reads: SELECT * FROM table WHERE colomn = <code class="php plain">2</code> .. wich will result in an error because the sql is no longer valid. So for now I use strip_tags to remove the code tag, but I find it not a very clean method. I couldnt find anything about this, so maybe someone can shed some light on this for me?

    - by fusion
    i'm calling the search.php page via ajax to search.html. the problem is, since i've implemented paging, the textbox with the search keyword from search.html 'disappears' when the user clicks the 'Next' button [because the page goes to search.php which has no textbox element] i'd like the textbox with the search keyword to be there, when the user goes through the records via paging. how'd i achieve this? search.html: <body> <form name="myform" class="wrapper"> <input type="text" name="q" onkeyup="showPage();" class="txt_search"/> <input type="button" name="button" onclick="showPage();" class="button"/> <p> <div id="txtHint"></div> <div id="page"></div> </form> </body> search.php [the relevant part]: $self = $_SERVER['PHP_SELF']; $limit = 5; //Number of results per page $numpages=ceil($totalrows/$limit); $query = $query."

  • Using md5_file(); doesn't return the md5 sometimes?

I can't figure out why. Any ideas?

  • Decoding and caching json every 60 minutes

    - by Gary
    Hi, How do I do this on a php webpage? I want to get and decode a json string and display the results as html on my page, however, I don't want it hotlinking back to the source. If I could write the decoded string to a txt file say weather.txt on the server and keep the html formatting and do it so that the page won't fetch the json script until 60 minutes has passed since the last time it was fetched regardless of how many times the page is opened during that 60 minute period and the weather.txt is viewed. All I can come up with is a simple script that hotlinks, everything else I have tried simply failed. $file = file_get_contents('http://sample.com/weather'); $out = (json_decode($file)); echo $out-mainText; Will appreciate any help with this.

  • different explanation

    - by Delirium tremens
    The following code echoes 5, not 10: $global_obj = null; class my_class { var $value; function my_class() { global $global_obj; $global_obj = &$this; } } $a = new my_class; $a->my_value = 5; $global_obj->my_value = 10; echo $a->my_value; "Upon first examination, it would seem that the constructor of my_class stores a reference to itself inside the $global_obj variable. Therefore, one would expect that, when we later change the value of $global_obj-my_value to 10, the corresponding value in $a would change as well. Unfortunately, the new operator does not return a reference, but a copy of the newly created object." Please, give me a different explanation.

  • INET_ATON() and INET_NTOA() in PHP?

    - by blerh
    I want to store IP addresses in my database, but I also need to use them throughout my application. I read about using INET_ATON() and INET_NTOA() in my MySQL queries to get a 32-bit unsigned integer out of an IP address, which is exactly what I want as it will make searching through the database faster than using char(15). The thing is, I can't find a function that does the same sort of thing in PHP. The only thing I came across is: http://php.net/manual/en/function.ip2long.php So I tested it: $ip = $_SERVER['REMOTE_ADDR']; echo ip2long($ip); And it outputs nothing. In the example they gave it seems to work, but then again I'm not exactly sure if ip2long() does the same thing as INET_ATON(). Does someone know a PHP function that will do this? Or even a completely new solution to storing an IP address in a database? Thanks.
