php - Using $_get on URL that is linked to id in database row -

-

i'm trying $_get part of url in href. want happen when click link redirected specific link. if makes sense.

i have 2 functions:

first function, list of links:

function showposts() {     $sql = ("select * blog");     $query = mysql_query($sql);      while ($row = mysql_fetch_array($query)) {         $listid = $row["blog_id"];         $showtitle = $row["title"];         $showcontent = $row["content"];         $showtimestamp = $row["timestamp"];          echo'             <div>             <a href="index.php?option=blog&task=view&id='$listid'"><h3>'.$showtitle.'</h3></a>                 <div>'.$showcontent.'</div>                 <p>'.$showtimestamp.'</p>             </div>         ';     } }

second function, redirect link:

function viewpost() {      if(empty($_get['id']) ) {         $listid = '';        } else {         $listid = $_get['id'];     }      $sql = ("select title, content, timestamp blog blog_id='$listid'");     $query = mysql_query($sql);      while ($row = mysql_fetch_array($query)) {         $showtitle = $row["title"];         $showcontent = $row["content"];         $showtimestamp = $row["timestamp"];          echo'             <div>                 <h2>'.$showtitle.'</h2>                 <p>'.$showtimestamp.'</p>                 <div>'.$showcontent.'</div>             </div>         ';     } }

as can see i'm using $_get['id'] here , read $_get can used retrieve passed url parameters.

the way have set url defined set of variables in switch.

if(empty($_get['task']) ) {     $task = 'show';  } else {     $task = $_get['task']; }   switch ($task){     case "create":         createpost();                break;     case "save":         savepost();         break;     case "show":         showposts();         break;     case "view":         viewpost();         break;     default:    echo'something went wrong!'; }

currently when click link, redirects of content related id not there.

edit

i figured out wrong in code. in sql statement used dots(.) inside apostrophes(') separate themselfes variable. when removed dots worked fine. 

blog_id='.$listid.'

not sure why used dots in first place? :/

also removed die's in switch per instruction 1 answer.

you misusing die() command in switch. die command used handle errors, stops script execution , returns error message set argument. try removing it.

C# random value from dictionary and tuple -

i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
