  • how to get something to display only once in a while loop

    - by Matt Nathanson
    I've got a mysql query running and it checks to see if an iterator is equal to 1, then display this div title... if ($this->dliterator == 1) {echo "<div class='clientsection' id='downloads'>Downloads</div><br/>";}; The problem is, is that the dl iterator may not necessarily start at 1. (it is directly related to a downloadid from the database). How can I get this to display only for the first time through the loop ONLY? while ($row = mysql_fetch_assoc($result)) { if ($row['download'] != null){ if ($this->dliterator == 1) {echo "<div class='clientsection' id='downloads'>Downloads</div><br/>";}; if ($editDownload == 1) { echo "<div class='clientlink' style='margin-top: 15px;'>"; echo "<input name='downloads[$this->dliterator][name]' type='text' id='download$this->dliterator' value='" . $row['download'] . "'/>"; echo "<input name='downloads[$this->dliterator][title]' type='text' id='downloadtitle$this->dliterator' value='" . $row['downloadtitle'] . "'/>"; echo "<img class='removelink' src='/images/deletelink.png' width='15' />"; echo "<input id='downloadid' name='downloads[$this->dliterator][id]' type='hidden' value='".$row['downloadid']."' style='display: none'/>"; echo "<br/><img id='uploaddownload$uploaditerator' class='uploaddownload' src='../images/upload.png' width='80'/>"; echo "</div>"; }; }; $this->dliterator++; $uploaditerator++; };

  • detect a string contained by another discontinuously

    - by SpawnCxy
    Recently I'm working on bad content(such as advertise post) filter of a BBS.And I write a function to detect a string is in another string not continuously.Code as below: $str = 'helloguys'; $substr1 = 'hlu'; $substr2 = 'elf'; function detect($a,$b) //function that detect a in b { $c = ''; for($i=0;$i<=strlen($a);$i++) { for($j=0;$j<=strlen($b);$j++) { if($a[$i] == $b[$j]) { $b=substr($b,$j+1); $c .=$a[$i]; break; } } } if($c == $a) return true; else return false; } var_dump(detect($substr1,$str)); //true var_dump(detect($substr2,$str)); //false Since the filter works before the users do their posts so I think the efficiency here is important.And I wonder if there's any better solution? Thanks!

    - by Sahal
    How can i see how many number of connections are opened in one request. (mysql_connect) I know that if i call mysql_connect function 100 times, function will return the connection link which is already opened only if parameters of the function is same. It will not request for new connection if connection is already exists. But i just want to make sure mysql_connect is not requesting new. I am working with a legacy system which contains so many "mysql_connect" function. Is there any setting in apache or is there any way i can log this number of connection value in apache or mysql log file? Please help.

  • How can I split a list with multiple delimiters?

    - by Rob
    Basically, I want to enter text into a text area, and then use them. For example variable1:variable2@variable3 variable1:variable2@variable3 variable1:variable2@variable3 I know I could use explode to make each line into an array, and then use a foreach loop to use each line separately, but how would I separate the three variables to use?

  • WordPress [img] tags

    - by Lokheed
    Hey guys, I'm trying to allow that standard BB [img] [/img] tags on my WordPress blog. I got this snippet from the net, but it only works on lower case [img] tags. I'd like it to apply to both [img] and [IMG]. As you can tell, I'm totally not a coder. function embed_images($content) { $content = preg_replace('/\[img=?\]*(.*?)(\[\/img)?\]/e', '"<img src=\"$1\" alt=\"" . basename("$1") . "\" />"', $content); return $content; } add_filter('comment_text', 'embed_images'); I know '||' is 'or' but don't know enough coding to make the changes. Any help is greatly appreciated. Thanks.

  • For securing forms, when do I issue the token?

    - by AQuestionADayKeepsTheDrAway
    So, I have a form, to make it a little more secure and potentially help prevent CSRF attacks I want to add a random token value in a hidden field that value is also stored server side in my session data. When should I issue a new token? Per form? Per page load where there is any form? Per session? I can render it invalid as soon as a form is successfully submitted but I'm wondering when to generate one. I ask as if I issue it per form or per page do I not risk the chance of a duplicate token value overwriting the existing (valid) token if a user opens a separate window but submitting the first form (with the now overwritten value)?
