if i write code php same:
<?php
$title = strip_tags($_POST['title']);
?>
unknown error show!
Notice: Undefined index: title in C:\xampp\htdocs\file.php on line 3
$_POST has value, after submitting form, so before that anybody can't use $_POST ..
<?php
if(isset($_POST['title'])){
//Here in condition if(array_key_exists ( 'title' , $_POST )) can also be checked...
//OR if(!empty($_POST)) OR if(!empty($_POST['title'])) can also be put..
$title = strip_tags($_POST['title']);
}
?>
If both form and action in the same page, the first load will show error as there is no data posted. So first checj whether a POST has been made and then assign. Try this
$title = "";
if(isset($_POST['title'])){
$title = strip_tags($_POST['title']);
}

any help you offer on this will be useful. Am working on my school project and this error code keeps popping up on the application "Undefined index: client_id" on line 1001"
Here is the code
public function onNewclientaddress(){
$addShipmentForm = Settings::get('addShipmentForm',true);
$data = post();
= \Spot\Shipment\Models\Address::where('user_id', $data['client_id'])->update(['default' => 0]);
if ( $addShipmentForm == "add_form_normal"){
$subitem = new \Spot\Shipment\Models\Address;
$subitem->name = htmlspecialchars($data['street_addr']);
$subitem->user_id = htmlspecialchars($data['client_id']);
$subitem->street = htmlspecialchars($data['street_addr']);
$subitem->city = htmlspecialchars($data['city_id']);
$subitem->zipcode = htmlspecialchars($data['postal_code']);
$subitem->country = htmlspecialchars($data['country_id']);
$subitem->default = 1;
$subitem->created_at = \Carbon\Carbon::now();
$subitem->updated_at = \Carbon\Carbon::now();
$subitem->save();
}
else{
line 1001 is the first line of code in the post. please pardon my English
This error indicates that $data['client_id'] is not being set. You will need to ensure that whatever form is providing this data, is passing client_id correctly.
You can see what is currently in $data with a line like:
die(var_dump($data));
This will output the data on the page.
Ensure your client_id field in your form has a name attribute:
name="client_id"

php code:
1. if (isset($data['city_id']))
2. {
3. $city_id = "city_id='". $data['city_id']. "', ";
4. }
And I get:
Notice: Undefined index: city_id on line 3
How can this be?
Just ran your code sample and it works perfectly, I do not get 'undefined index' error - taking us to the big apple
<?php
$data['city_id']='New York';
if (isset($data['city_id']))
{
$city_id = "city_id='". $data['city_id']. "', ";
echo $city_id;
}
?>
output: city_id='New York',
Surely, without the $data['city_index']='New York'; I just get a blank screen, as the if condition is not met - no errors.

I'll get the error
Notice: Undefined index: page in C:\xampp\htdocs\ajaxx\load_page.php on line 3
This is my full code:
<?php
if(!$_POST['page']) die("0");
$page = $_POST['page'];
if(file_exists('pages/page_'.$page.'.html'))
echo file_get_contents('pages/page_'.$page.'.html');
else echo 'There is no such page!';
?>
It was working yesterday but all of a sudden it gives me this error. The full code is downloaded from A simple AJAX website with jQuery
$_POST['page'] does not exits.
In my experience the $_POST value is always set so doing isset("..") ensures ['page'] is sent. I think 'page' is not been posted. It may be good to do a print_r($_POST) and see what is posted.
if( isset($_POST['Page']) )
{
$page = $_POST['page'];
if(file_exists('pages/page_'.$page.'.html'))
echo file_get_contents('pages/page_'.$page.'.html');
else echo 'There is no such page!';
}
else
echo "Value not posted";

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!";

the message is
Notice: Undefined index: flag in C:\xampp\htdocs\myfiles\mobile tracking\index.php on line 63
my code is
<?php
$stat=$_REQUEST['flag'];
if($stat=="FAILED")
{
echo "Username/password doesnot exists";
}
?>
The global variable $_REQUEST['flag'] is probably having value NULL. This is the reason you are getting this error. Well, try using isset(). to check whether the variable is having any value or not.
You should check if the $_REQUEST['flag'] variable has been set:
<?php
$stat= ( isset($_REQUEST['flag']) ? $_REQUEST['flag'] : null) ;
if($stat=="FAILED")
{
echo "Username/password doesnot exists";
}
?>
You received a notice because you didn't initialized the values of the array. Use this construction to prevent them.
if (! array_key_exists('flag', $_REQUEST)) {
$_REQUEST['flag'] = whatever value goes here;
}
