I am getting "Undefined Index FruitOrder" in an if statement for an array which is created from XML/Soap Response
Code:
$response = preg_replace("/(<\/?)(\w+):([^>]*>)/", "$1$2$3", $resp);
$xml = new SimpleXMLElement($response);
$body = $xml->xpath('//soapBody ')[0];
$array = json_decode(json_encode($body), TRUE);
if($array['FruitOrder']['FruitCode'] == 'FruitSuccess' || $array['FruitOrder']['FruitCode'] == 'FruitSuccessWarnings')
{
To avoid the Undefined Index error you should check if the item ['FruitOrder']['FruitCode'] exists in the array with isset.
if(isset($array['FruitOrder']['FruitCode'])
&& ($array['FruitOrder']['FruitCode'] === 'FruitSuccess'
|| $array['FruitOrder']['FruitCode'] === 'FruitSuccessWarnings'))
{
echo 'process the data';
}

I'm getting an undefined offset error
<?php
function ara($one, $two, $three)
{
#preg_match_all('/' . preg_quote($one, '/') .
'(.*?)'. preg_quote($two, '/').'/i', $three, $m);
return #$m[1];
}
$link = "example.com";
$article = file_get_contents($link);
$sport = ara('data-bin="','"',$article);
$channel = ara('data-videobin="','"',$article);
for ($i=0;$i<50;$i++)
echo"<span class='linko'><a target='_blank' href='example.org/live1.php?id=".($channel[$i]."'>$sport[$i]</a>"."<br></span>"); // error is here
?>
How can I fix it? I'am waiting for your helps. Thanks.
These codes are for a live channel website.
The channel variable has less than 50 elements.
Usually in a loop, you should set the end condition to the size of the array.
for ($i=0;$i<sizeof($channel);$i++)

I'm in a ambiguous situation.
Here's the concerned code:
http://prntscr.com/9edm4j
public function verifyReply($reponse)
{
$qr = $this->mStopBOT;
if(isset($_SESSION["stopBOT"]))
{
if($_SESSION["stopBot"] === false)
{
$_SESSION["stopBOT"] = true;
if($qr[$_SESSION["stopBOTq"]][1] == $reponse)
return true;
}
}
return false;
}
And here is the problem:
http://prntscr.com/9ednwm
PHP Notice: Undefined index: stopBot in /home/*************/public_html/inc/classes/Security.inc.php on line 92
The isset() function returns true, but when I use the function, it says that the index is undefined! ?
Regards and Thanks in Advance
You are checking if $_SESSION['stopBOT'] is set but then use $_SESSION['stopBot']
Note the case difference, stopBOT vs stopBot

This is my code:
$button = $_GET ['submit'];
$search = $_GET ['search'];
if(!$button)
echo "you didn't submit a keyword!";
else
And I'm getting this error:
Undefined index: search in C:\wamp\www\search1 (2).php on line 4
Use isset() before reading an array key in $_GET/$_POST/$_REQUEST.
$button = isset($_GET['submit']) ? $_GET['submit'] : false;
$search = isset($_GET['search']) ? $_GET['search'] : false;
if(!$button) echo "you didn't submit a keyword!";

<?php
$qr_topic = #mysql_query("SELECT * FROM topics");
while ($topic = #mysql_fetch_array($qr_topic)) {
$highlight = "";
**if ($topic['name'] == $_GET['topic'] || $post['topic_id'] == $topic['id']) {**
$highlight = "class='highlight'";
}
echo "<li ".$highlight."><a href='index.php?topic=".$topic['name']."'>".$topic['name']."<img src='img/".$topic['image']."' width='195' height='90' /></a></li>";
}
?>
Getting Undefined index error, not sure what is wrong ? This could be the line for error.
if ($topic['name'] == $_GET['topic'] || $post['topic_id'] == $topic['id']) {**
You try to use $_GET['topic'] without checking if it exists first, that's why you get that error. I'd recommend you to test if the variable exists first using is_set() or empty().

When I try to use the user_name from $_SESSION I get the error
'Undefined index: user_name'
CODE:
$_SESSION['signed_in'] = true;
while ($row = $query1->fetch(PDO::FETCH_ASSOC))
{
$_SESSION['user_id'] = $row['user_id'];
$_SESSION['user_name'] = $row['user_first_name'];
}
echo 'Welcome, ' . $_SESSION['user_name'] . '. Proceed to the overview page to see your tasks.';
Add session_start(); on top of your page to start the session.
