Can't seem to get this working.

navpath.php

<br><br><img src='./images/nav.png'> <a href='./index.php?act=idx'><? echo FORUM_NAME; ?></a>
<?
    if ($act != idx) {
    if ($act == viewforum) {
        $forumId = $_GET['forumid'];
        $PathQuery = "SELECT * FROM "+FORUM_NAME_TABLE+" WHERE forum_id='"+$forumId+"'";
        $PathResult = mysql_query($PathQuery, $db);
        $CatID = mysql_result($PathResult, 0, 'cat_id');
        $ForumTitle = mysql_result($PathResult, 0, 'forum_name');
        $CatQuery = "SELECT cat_name FROM "+FORUM_CAT_TABLE+" WHERE cat_id='"+$CatID+"'";
        $CatResult = mysql_query($CatQuery, $db);
        $CatName = mysql_result($CatResult, 0, 'cat_name');
        ?>
        · <a href='./index.php?act=viewcat&catid="<? echo $CatID; ?>"'> <? echo $CatName; ?>
        · <a href='./index.php?act=viewforum&forumid="<? echo $forumId; ?>"'><? echo $ForumTitle; ?>
            <?
    }

This is meant to select the information from the address bar with $_GET and then read relavent information from the db.

Basically what i'm doing is making a forum system from scratch using 1 file that users will access. Heres the index page:

<?php include("headers.php"); ?>

<table width="760" border="0" align="center" cellpadding="3" cellspacing="0" bgcolor="#979797" height="100%" bordercolor="#000000" bordercolordark="#000000" bordercolorlight="#000000">
<tr> 
<td width="100%" height="100%" bgcolor="979797" bordercolor="#000000" bordercolorlight="#000000" bordercolordark="#000000" valign="top">
    
<!-- Header/Logo Section -->
<div id="logostrip">
    <center><a href="./index.php?act=idx"><img src="./images/logo.png" alt="Forum Index" Border="0"></a></center>
</div>
<!-- End Head/Logo -->
        
<!-- Navigation -->      
<?php include("navigation.php"); ?>
<!-- End Navigation -->
<div align='center' style='margin-bottom:3px;'></div>

<!-- User Nav -->
<?php include("usernav.php"); ?>

<!-- Navigation Path -->
<?php include("navpath.php"); ?>
</td>
</tr>
</table>
</body>
</html>
<?php
mysql_close($db);
?>

if (!isset($_GET['act'])) {
    if (!isset($_POST['act'])) {

    }
    if (isset($_POST['act'])) { 
        $act = $_POST['act']; 
    }
}
if (isset($_GET['act'])) { $page = $_GET['act']; }
if (isset($_SESSION['SESS_MEMBER_ID'])) {
    $memid = $_SESSION['SESS_MEMBER_ID'];
}
if (isset($memid)) {
    $db = mysql_connect(MSQL_HOST, MYSQL_USER, MYSQL_PASS);
    mysql_select_db(MYSQL_DB_NAME);
    $query_meminfo = "SELECT * FROM " + MYSQL_DB_NAME + "." + MYSQL_PROFILE_TABLE + " WHERE `user_id`="+ $memid;
    $query_result = mysql_query($db, $query_meminfo);
    $MemName = mysql_result($query_result, 0, 'display_name');
    $MemGroup = mysql_result($query_result, 0, 'Group');

What it is doing so far is everything in index.php/headers.php and then when it gets to navpath.php it only displays the forum name with the initial image. Why won't it get the whole navigation path if I use adress.com/index.php?act=viewforum&forumid=1

Do you have display_errors = On and error_reporting = -1 in your php.ini file? Is idx a defined constant?

RaythMistwalker · October 23, 2011

I Don't have access to php.ini to see if they are on. Is there a way to set it per script?

Also idx is the way index.php knows what to display once I get it so the address would be index.php?act=idx OR act=something (As shown in headers.php)

Pikachu2000 · October 23, 2011

You can set error reporting per script with this, it won't work if there's a fatal parse error.

ini_set('display_errors', 'On');
error_reporting(-1);

In these 2 lines, you're comparing the value of a variable to the value of a constant. To compare to string values, they'd need to be quoted. In most cases, if a comparison is done in that manner, php is smart enough to realize that no constant is defined by that name, and juggles it to a string comparison, but that takes time, and it can cause major headaches if a constant actually is defined by that name.

if ($act != idx) {
    if ($act == viewforum) {

Consider what happens in this scenario:

config.php

<?php
//site constants
define( 'idx', 'index.php');

index.php

<?php
require_once( 'config.php' );

// incoming $_GET['page'] = 'idx'

if( $_GET['page'] == idx ) {
     // do something
}

The above comparison will return FALSE even though $_GET['page'] = 'idx' because it's being compared to value of the constant idx.

RaythMistwalker · October 23, 2011

Ok I fixed the code so the different parts are quoted (ie $act != 'idx') and then turned errors on. The following errors were returned on index.php?act=viewforum&forumid=1

Notice: Undefined variable: act in /home/rayth/public_html/navpath.php on line 7

Notice: Undefined variable: act in /home/rayth/public_html/navpath.php on line 8

Notice: Undefined variable: act in /home/rayth/public_html/navpath.php on line 22

Notice: Undefined variable: db in /home/rayth/public_html/index.php on line 33

Warning: mysql_close(): supplied argument is not a valid MySQL-Link resource in /home/rayth/public_html/index.php on line 33

both variables act and db are defined in headers.php which is the first file included in index.php

xyph · October 23, 2011

Obviously they are not, or your script wouldn't be saying they were undefined.

In other words, if $_POST['act'] doesn't exist, neither will $act.

RaythMistwalker · October 23, 2011

Ok I fixed that problem with the variable and now Apparently there is a problem with the last 2 lines here: (12 & 13)

10        $PathQuery = "SELECT * FROM "+FORUM_NAME_TABLE+" WHERE forum_id='"+$forumId+"'";
11        $PathResult = mysql_query($PathQuery, $db);
12        $CatID = mysql_result($PathResult, 0, 'cat_id');
13        $ForumTitle = mysql_result($PathResult, 0, 'forum_name');

Errors:

Warning: mysql_result(): supplied argument is not a valid MySQL result resource in /home/rayth/public_html/navpath.php on line 12

Warning: mysql_result(): supplied argument is not a valid MySQL result resource in /home/rayth/public_html/navpath.php on line 13

Warning: mysql_result(): supplied argument is not a valid MySQL result resource in /home/rayth/public_html/navpath.php on line 16

You need to use the period (.) to concatenate strings not the plus sign (+).

xyph · October 23, 2011

Under what conditions would mysql_query not return a resource?

RaythMistwalker · October 23, 2011

You need to use the period (.) to concatenate strings not the plus sign (+).

~juddster

Last I checked + or . would join strings together.

@xyph: I would assume the only time this wouldn't work is if the query didn't go through.

xyph · October 23, 2011

This is true. You don't have to assume if you check out the manual

http://php.net/manual/en/function.mysql-query.php

Look at the 'Return Values' section.

If you scroll down to 'See Also' you will find a function called mysql_error(). That might help you in finding out exactly why the query didn't go through.

And no, only . can be used for concatenation in PHP.
