The input value takes the id of the video, I didn't know of any other work around for that. I'd like to delete the video that corresponds with the button pressed, if that makes sense. Anyways, I would like to delete the video where the video id is equal to the video id of the input or the value of the input pressed. I am positive the way I am carrying this out is not correct, as I am thrown an 'index undefined error'. Here is the disgusting code at hand. Recommendations are appreciated, but please try and keep answers in line with the relevant information given. Thank You.

How do I get my session to be unset? My form looks like this:
foreach ($joined as $i => $qty){
echo "<form action='' method='get' name='yourForm'>";
echo "<button type='submit' name='remove_" . $i . "' value='remove_" . $i . "' class='deletebtn' >X</button>";
echo "</form>";
}
My SESSION is defined like this:
for($i=0; $i<=5; $i++){
if (isset($_REQUEST["element_id_$i"]) ) {
$_SESSION["element_id_$i"] = $_REQUEST["element_id_$i"];
$id = $_SESSION["element_id_$i"];
array_push($_SESSION["element_id"],$id);
}
$id = $_SESSION["element_id"];
}
and the form submits to:
if (isset($_REQUEST["remove_$i"]) ){
unset($_SESSION["quantity[$i]"]);
unset($_SESSION["element_id[$i]"]);
var_dump($_SESSION["element_id"]);
var_dump($_SESSION["quantity"]);
echo "Received variable " . $_REQUEST["remove_$i"];
echo 'TARGET INDEX TO BE REMOVED: ' . $_SESSION["element_id[$i]"] . '<br><br>';
}
The output is:

I tried to use isset but then it just threw out a different error. The section of code that is causing the errors is: if ( $_GET['action'] != "login" && $_GET['action'] != "logout" && !$_SESSION['username'] ){ //ITS SHOWING 2 ERRORS WITH ACTION ON THIS LINE login(); exit; } switch ( $_GET['action'] ) { //IT ALSO HAS AN ERROR FOR ACTION ON THIS LINE case 'login': login(); break; case 'logout': logout(); break; I would really appreciate the help as it's been annoying me and i'm having a mental blog. Thanks in advance. I get this error

I have a really simple e-mail form that I made a while ago. I'm trying to make a simple modification, but I'm getting a a logical error somewhere. The problem is with the one optional variable ($wholesale) that gets sent to the PHP script. If the user has clicked the box on the form and the $wholesale variable has something in it, the message gets sent without an error. But if the user leaves the box blank, nothing is in the variable and PHP has a problem with that. It'll still send the e-mail, but I get a Notice: Undefined index: wholesale in /file/path/on our/sever.com/send_form_email.php on line 35 error. Here's a part of the code: // validation expected data exists if(!isset($_POST['first_name']) || !isset($_POST['last_name']) || !isset($_POST['email']) || !isset($_POST['street_address']) || !isset($_POST['city']) || !isset($_POST['state']) || !isset($_POST['zip']) || !isset($_POST['phone'])) { died('We are sorry, but there appears to be a problem with the form your submitted.'); } $first_name = $_POST['first_name']; // required $last_name = $_POST['last_name']; // required $email_from = $_POST['email']; // required $street_address = $_POST['street_address']; // required $city = $_POST['city']; // required $state = $_POST['state']; // required $zip = $_POST['zip']; // required $phone = $_POST['phone']; // required $wholesale = $_POST['wholesale']; // not required // I don't see why this isn't solving the problem if ( $_POST['wholesale'] == null ) { $wholesale = "."; } ... then the code formats and sends the e-mail out. Any help would be awesome... this is such a simple thing that I honestly can't think of what else to try... I am working on building a newsletter with PHP. I have gotten everything to work but the pulling of the email address.
First is the sendnl.php file
<?php
require("../PHPMailer/class.phpmailer.php");
include 'includes.php';
$mail = new PHPMailer;
$subject = $_POST['subject'];
$text = $_POST['newsletterBody'];
$mail->IsSMTP();
$mail->Host = 'localhost';
$mail->Port = '465';
$mail->SMTPAuth = true;
$mail->Username = '******USERNAME';
$mail->Password = '*****PASSWORD';
$mail->SMTPAuth = true;
$mail->SMTPSecure = 'ssl';
$mail->From = '***EMAIL';
$mail->FromName = '****FROMNAME';
$email = getEmail("73", $DBH);
foreach ($email as $nlEmail)
{
$addEmail = $nlEmail->email;
$mail->AddAddress($addEmail);
$DBH = null;
$addEmail = "";
}
$mail->AddReplyTo('******EMAIL', '*****EMAILNAME');
$mail->WordWrap = 50;
$mail->IsHTML(true);
$mail->Subject = $subject;
$mail->Body = $text;
$mail->AltBody = $text;
if(!$mail->Send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
exit;
}
echo 'Message has been sent';
?>
Next is part of the includes file going over the function and class
function getEmail($inId, $DBH)
{
if (!empty($inId))
{
$blogstmt = $DBH->prepare("SELECT email_addr FROM newsletter_emails WHERE id = :userId");
$blogstmt->bindParam(":userId", $inId, PDO::PARAM_STR, 6);
$blogstmt->execute();
}
else
{
$blogstmt = $DBH->prepare("SELECT * FROM newsletter_emails");
$blogstmt->execute();
}
$postArray = array();
$results = $blogstmt->fetchAll(PDO::FETCH_ASSOC);
foreach($results as $row){
$myPost = new nlEmails($row["id"], $row['email'], $DBH);
array_push($postArray, $myPost);
}
return $postArray;
$DBH = null;
}
class nlEmails {
public $id;
public $email;
function __construct($inId=null, $inEmail=null, $DBH)
{
if(!empty($inId))
{
$this->id = $inId;
}
if(!empty($inEmail))
{
$this->email = $inEmail;
}
}
}
It gives me an Unidentified index error message for the "id" and "email" used in the getEmail function.
Thanks for any help or pointers.

Thanks in advanced. I have a simple problem but seem to be hitting a roadblock with fixing it. I am in the process of upgrading a site from PHP 5.6 to 7.0 (eventually to 7.2) I am seeing error notices like PHP Notice: Undefined index: productpage in ….. I know this it because the $_REQUEST can sometimes be empty depending on what data is passed back and when certain pages are loaded $productpage = mysqli_real_escape_string($con, $_REQUEST['productpage']); I also know that I could turn the error notice off or use isset to check $_REQUEST but I would prefer to use the ?? '' option to fix this issue. The problem is that when I add the ?? '' option to the above code the problem resolved itself but then moments later the same error on the same line reappeared in the error logs and I cant understand why. Can someone give me the correct example of where to place ?? '' in the above code so that I can rule out my potentially dodgy code as being the reason the error keeps reappearing.

Here is the error I get: Notice: Undefined variable: id in /opt/lampp/htdocs/EMC/customer-search.php on line 248 Notice: Undefined index: Page in /opt/lampp/htdocs/EMC/customer-search.php on line 255 Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in /opt/lampp/htdocs/EMC/customer-search.php on line 302 And my code for second error: Code: [Select] $Per_Page = 2; // Per Page $Page = isset($_GET["Page"]); if (!$_GET["Page"]) { $Page=1; } I'm not really sure what's the problem with my first and third error so I will post the whole code he Code: [Select] <?php require_once("./include/fg_membersite.php"); require_once("./include/membersite_config.php"); $objConnect = mysql_connect("localhost","root","") or die(mysql_error()); $objDB = mysql_select_db("EMC"); $haha = $fgmembersite->UserEmail(); $_SESSION['storedemail']= $haha; $query4 = mysql_query("SELECT * FROM Register WHERE Email= '$haha'"); while ($row4 = mysql_fetch_array($query4)){ $id = $row4['ID']; } mysql_free_result($query4); ?> <html> <body> <form name="frmSearch" method="get" action="<?=$_SERVER['SCRIPT_NAME'];?>"> <table width="599" border="1"> <tr> <th>Keyword <input name="txtFirstName" type="text" id="txtFirstName" value="<?= isset($_GET["txtFirstName"]) ;?>"> <input name="txtLastName" type="text" id="txtLastName" value="<?= isset($_GET["txtLastName"]) ;?>"> <input name="txtCell" type="text" id="txtCell" value="<?= isset($_GET["txtCell"]) ;?>"> <?

I am coding Arduino micro controller, and intended to GET the data from server MySQL db through php to turn ON/OFF LED. I could able to GET the data from manually updated MySQL db value, even I could able to successfully change the data of MySQL db from micro controller POST method. But I am getting error when trying to change the MySQL db value from browser using online POST tool, Following is PHP code at server

}
Post Command: http://url/MySQL_POST.php?api_key=XXXXXXXXX&id=1&status=on Response/Error: Notice: Undefined index: api_key in <PATH>/MySQL_POST.php on line 14 Wrong API Key provided.

There is also one called 'localhost/admin?limit=all' that is to show all the rows in one page.

if(isset($_POST["submit"]))
{
$date_col = "test";//this will be DateTime later
$name = $_POST["name"];
mysqli_query($connection, "INSERT INTO comment_table (name, date_col) VALUES ('$name', '$date_col')");

$comres = mysqli_query($connection, $comsql);

<p>Name: <strong><?php echo $comr['name']; ?></strong>This is the code that is being pointed to as undefined index. <?php echo $comr['date_col']; ?> </p>
<?php } ?>
</div>
The data I'm using for the date_col column is varchar and it should be Datetime but I don't know if that's the reason for the error. I would like to set $date_col equal to a Datetime expression for testing purposes but the formatting I chose wasn't working either.
