PHP - Why Isnt Isset Working? Whats Wrong With This?
Hello! This may sound like a stupid question but i have been trying to get this working all day and its driving me crazy.
Ive been asked to take over development of this project, he sent me his code and its a little out of date so im trying to update it. Here is what i cant work out.
I have this little snippet of code:
if ($page == "showthread"){
showThread();
}
There are several more like that, but you dont need a whole list.
That code seems to be throwing up this error when i go to that specific page:
Notice: Undefined index: error in .....
All well and good, i would usually do this:
if (isset($page) == "showthread"){
showThread();
}
Thats fine and dandy, the error goes away. But now, when i go to that page, it redirects me and gives me my error message for a non-existing page.
Its really frustrating me. Can you help me fix this little error?
Similar Tutorialshi all me again i have this bit of code mysql_connect($db_hostname,$db_username,$db_password); @mysql_select_db($db_database) or die( "Unable to select database"); $whereClauses = array(); if(isset($_GET['bi'])) { $whereClauses[] = "bi=1"; } if(isset($_GET['print'])) { $whereClauses[] = "print=1"; } if(isset($_GET['online'])) { $whereClauses[] = "online=1"; } $query = "SELECT * FROM `project` ORDER BY `project`.`position` ASC "; if(count($whereClauses)) { $query .= " WHERE " . implode(" AND ", $whereClauses); } with this error msg There was a problem with the SQL query: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE online=1' at line 3 I get this kinda error a lot as im still learning is there any way to better find out whats going wrong i use error_reporting(E_ALL); ini_set('display_errors', '1'); at the start of my scripts but it dont tell me a lot. i can work out it some thing to do with the $whereClauses as the page displays ok on show all. Im bit stumped here not even sure what to call the prob is it sql query error or php array problem thanks for any help can you tell me whats wrong with this? Code: [Select] <?php $age= 60; if( isset($_SESSION['logedin']) ) { $q = mysql_query('SELECT id=`$id`, DATE_FORMAT(`last_activity`,"%a, %b %e %T") as `last_activity`,UNIX_TIMESTAMP(`last_activity`) as `last_activity_stamp`FROM `mymembers`WHERE `$logOptions_id` <> "'.($_SESSION['logedin']).'"'); $isonlinecheck = mysql_query($q); if ($isonlinecheck ="last_activity_stamp + $age "< time()){ $isonline = "is <font color='green'>online!</font>";} else { $isonline = "is<font color='red'> offline!</font>"; } } ?> Cant Figure Out Whats Wrong With it.. Code: Code: [Select] <?php if(isset($_SESSION['user'])) { $bb = mysql_query("SELECT * FROM main WHERE id=". $_SESSION['id']) or die ("An error has occured: " . mysql_error()); while($n=mysql_fetch_array($bb)) { ?> <div class='cs_article'> <div class='left'> <h2>User Control Panel</h2> <p><a href="usercp.php">User CP</a><?php if($n['rights'] == 1) { echo ", <a href="modcp.php">Mod CP</a>"; }?> <?php if($n['rights'] == 2) { echo ", <a href="aa/">Admin CP</a>"; }?> <div class='button'><a href='usercp.php'>Read more</a></div> </div> <div class='right'> <h1>User CP</h1> </div> </div> <?php }} ?> What its doing: Mod-Justin Compared to Mod-Justin Its a page 'Downloads'.

Edited by Metoriium, 25 October 2014 - 05:04 PM. Hello,
I am trying to make 'onclick img' that will provide a Linux command when clicked.
I've been trying this code:
<body>
<?php
include("connect.php");
include('Net/SSH2.php');
*** CONNECTION TO DATABASE MYSQL CODE ***
if(mysql_num_rows($result) > 0)
{
while($row = mysql_fetch_array($result))
{
$_SESSION['logged'] = true;
$ssh = new Net_SSH2('xx.xx.xx.xx');
if (!$ssh->login($info['username'], $info['password']))
{
exit('Connection to Linux has failed, please try again.');
}
echo '<form action="" method="GET">';
echo '<input type="image" src="start.png" width=100 height=100 name="start" />';
echo '</form>';
if(isset($_GET['start']))
{
echo $ssh->setTimeout(5);
echo $ssh->exec('(cd '.$info['username'].' ; nohup ./samp03svr &)');
}
}
}
else
{
$_SESSION['logged'] = null;
header("Location: loginfail.php");
}
?>
</body>
But when I clicked the image, it sends me to "loginfail.php".
Please help ><
