Never mind - figured out that I needed to add a "return false;" so that the script wouldn't move past that button. :)

Hi all, I have a form that uses CAPTCHA as a means of verification that the submitter is not spambot, or anything similar.  I have a button next to the place where the user is supposed to input the letters/numbers in the image: <button onclick="NewVerifyImage();">New image</button> ...and the NewVerifyImage() function looks like this: <script language="javascript" type="text/javascript"> var nReload = 5; function NewVerifyImage() {     if (nReload <= 2)         if (nReload <= 0)         {             alert("Sorry, too many reloads.");             return;         }         else             alert("Only " + nReload + " more reloads are allowed");     nReload--;     document.vimg.src = "verifyimg.php"; } // --> </script> This calls a script called verifyimg.php, which would generate a new CAPTCHA image and place it in the image called "vimg" - however, when I click this "New Image" button, it's as though I've clicked submit - the form goes to the page I redirect the user to when info has been submitted. Does anyone have any idea why it seems like this button is not calling the function properly? Thanks!

Okay, so I finally was able to echo my path, piece by piece, and this code: [code]echo $_GET['issue'].'/'.$_GET['article'].'.html'[/code] ...gave this result: sp06/1.html (when my URL was www.mydomain.com/articles.php?issue=sp06&issue=1) Still no dice - as I said before, the problem is (I believe) coming in the part of the code below that is the ELSE branch to the "file_exists" function: [code]<?php     if (isset($_GET['article']))     {         if (file_exists($_GET['issue'].'/'.$_GET['article'].'.html'))             include($_GET['issue'].'/'.$_GET['article'].'.html');         else             echo $_GET['issue'].'/'.$_GET['article'].'.html';     }     else     {         include($_GET[issue].'/default.html');     } ?>[/code] Since it's echoing the path correctly, that must mean that "file_exists" is having a problem with it. Unfortunately, I'm newbie enough to PHP that that doesn't help me. [b]EDIT:[/b] Okay, it definitely is "file_exists", because if I remove that, it includes correctly. However, now I've just left a huge hole in my site...sheesh. Does anyone know why this function is giving me so much trouble?

It looks like the file that will be included will be something like this: public_html/issue_dir/article_html.html I am assuming the public_html. At any rate, the problem I see is that you're GET[ ] needs to have 's around the strings, so $_GET['article'] instead of $_GET[article]. Otherwise I'm not sure what else is wrong. [/quote] The scary thing is that there is no error - it's just a blank page (with my main CSS layout). I tried adding 's around the variable names in $_GET[], but that didn't seem to help.

[/quote] Unfortuantely, that ALSO gives a blank page...it's baffling, because that should be right. I'm assuming it's incorrect because the desired results aren't appearing. :( I noticed that it echoes output in the ELSE part of the branch to check if the file exists or not...if that helps at all.

Hi all, I have this bit of code: [code]<?php     if (isset($_GET[article]))     {         if (file_exists($_GET[issue].'/'.$_GET[article].'.html'))             include($_GET[issue].'/'.$_GET[article].'.html');         else             include($_GET[issue].'/default.html');     }     else     {         include($_GET[issue].'/default.html');     } ?>[/code] What I need is this: if I have a URL that's something like - www.mydomain.com/articles.php?issue=sp06&article=1 - I want to use both the "issue" and "article" variables to descend into my directory structure and include the necessary article. The directory is something like this: articles.php sp06 -> 1.html 2.html ... fl06 -> 1.html 2.html ... ...and so on. The above implementation is incorrect - perhaps my knowledge of concatenation in PHP is flawed... Can anyone point me in the right direction? Let me know if the above info is not adequate. Thanks.

All you need do is check the file and querystring exist, if it does, include it, otherwise load a default. eg; [code] if (isset($_GET[article])) {   if (file_exists($_GET[article]."html")) {     include $_GET[article]".html";   } else {     include "default.html";   } } else {   include "default.html"; } [/code] PS: All this can easily be done in asp also. [/quote] How would I accomplish the above in ASP? For whatever reason, ASP is slightly more confusing to me...

Hi all, I'm fairly new to PHP, and I have a question about dynamic content that's loaded through a URL variable. My site uses a line like this: <?php include("$_GET[article].html") ?> ...to dynamically include text into a laid out page (in a URL like www.mysite.com/articles.php?article=34). I like this, because it's simple (whereas, in ASP, I would have to have a large case statement with every possible article). However, I'm wondering if it's possible to have "default content" should someone enter something like: www.mysite.com/articles.php (no variable on the end). Is this possible, while STILL keeping intact my one-line inclusion from above? Or is something like a case statement the only way to have "default content?" Thanks! :)
