Here's my problem: When someone creates a new ad, they can upload an image. If they upload an image, but end up not creating the ad, I need to delete the image. Do you think this is the best way to do it? [/quote] Its ok to have a clean-up process on an aborted transaction. Another solution is that, because it sounds like an image is optional, only allow image to ads that have been already been created.

    A couple of ways that you can use. [b]1) Put your html in print statements:[/b] [code]    print "<htm>" .         "<head><title> $pageTitle </title></head>" .         "<body>"; /* etc */ [/code] [b]2) Use place holders and then parse your text.[/b] [code]$html = <<< HTML <h2>[TITLE]<h2> Posted [DATE] by [AUTHOR] HTML; $search = array($postTitle, $postDate, $postAuthor); $repace = array('[TITLE]', '[DATE]', '[AUTHOR]'); $html = str_replace($search,$replace,$html); print $html; [/code] The good thing about the second method is that you can read that from a file. I typically have html files with variable place holders for different sections of the page (header, footer, navbar, etc). The best thing about this method is that you are separating your content from your code. If you do it properly, you can adjust one without messing up the other. Also works well when you start working with someone who has little or no programming knowledge.

    The problem is that you arent handling the case of when youve found the parent array. Youre only looking for correct values. You have to be able to single all the way up the stack that its succeeded. [code] function getNavItemIndex($navItem, $haystack) {    $thisIndex = false; //default case    foreach ($haystack as $k => $v)    {       if (is_array($v))       {          $recurNdx = getNavItemIndex($navItem, $v);          if ($recurNdx !== false) //found in recursive call             return "[$k]$recurNdx";       } else          if ($v == $navItem) //found here.             return "[$k]";    }    return $thisIndex; } [/code] Should return "[2][name]"

[/quote] The other problem is this: $num=mysql_numrows($result); Theres no such thing as mysql_numrows() its mysql_num_rows(). This will make $num = null which is why that loop is never entered. Dont you have error messages turned on?

I have classifieds php script. When a user registers it works fine, they can place an ad and it all gets stored in mysql database. But when they try to update their ad it lets them do it but when we go back and look at the ad it is still the same. In mysql nothing has been changed. Why isnt it updating? What should i look for? If i post that specific php file here would anyone be able to figure out? Would anyone like to take a look at my script and see. [/quote] Yeah, post the part where you are updating the database.

[/quote] Thats not redefinition, its concatenation. Notice the .=? Its like saying $form = $form . "string"; The problem is actually in your html, not your php. A submit button isnt of type button, its of type submit. <input type="Submit" name="Submit" />

[/quote] Ok, when I remove the clutter of the <? ?> tags, you get this: [code] $user = "user"; $pass = "pass"; $dbase = "localhost"; $uname = $_POST['user']; $upass = $_POST['pass']; $connection = mysql_connect("localhost",$user,$pass) or die ("Error Connecting to DBase"); mysql_select_db($dbase,$connection) or die ("Error Connecting to table"); $result = mysql_query("SELECT * FROM usertb",$connection) or die ("Error querying DBase"); $i = 0; while($result_ar = mysql_fetch_assoc($result)) {    mysql_close();    ob_start();    if ($upass == $result_ar['upass'] && $uname == $result_ar['uname'])    {       header("Location: clients/myoxy/index.html");    }    else       header("Location: index.html");    $i+=1; } [/code] I don't really know why youre using an ob_start() (especially without a ob_flush()) and you are also closing your connection multiple times. I'm not sure of the effect on the ob_start() and multiple header() calls, but there is no way that the results you will get from that are what you are actually looking for. Try something like this: [code]$found = false; while ($result_ar = mysql_fetch_assoc($result)) {    if (($upass == $result_ar['upass']) && ($uname == $result_ar['uname']))    {       $found = true;       break;    } } if ($found) { //valid login    header("Location: clients/myoxy/index.html"); } else { //invalid login    header("Location: index.html"); } [/code]

    If theyre numbers, SELECT * FROM activity WHERE time BETWEEN 2006030700000 AND 2006070700000 If theyre dates, then you can use BETWEEN TO_DATE(start) AND TO_DATE(end). etc.

Does anything else seem like it could be causing a problem? [/quote] It definately has to be something with that database query. The only way for mysql_result to fail when asking for the 0th paramater is for either no rows to be returned or an invalid query. Because $name is the only thing that isnt hardcoded into that query, and the fact that it works once, you have to be able to track it to that (or the database connection settings.) Why not do a print $query at that point and see what the output is at run-time.
