in my PHP code user can guess a number. variable 'number' in line 3 has been sent with post method which is in the same page and the code is called by 'PHP_SELF' and 'number' count number of guess but an error occurred in line 3 with this description: Notice: Undefined index: try
<?php
$target=13;
$try=(isset($_POST['number'])) ? $try+1 : 1;
if(!isset($_POST['guess'])){
$message="welcome to geuss machine";}
elseif(!is_numeric($_POST['guess'])){
$message="inpute is unidentify";}
elseif($_POST['guess']<$target){
$message="it's to small!";}
elseif($_POST['guess']>$target){
$message="it's to big!";}
elseif($_POST['guess']=$target){
$message="you win number was:$target";}
else
$message="it's confusing!";
?>
but in other system is working correctly.
is it related to Apache setting?
Your code doesn't make sense:
$try=(isset($_POST['number'])) ? $try+1 : 1;
means if number is set, then increment an undefined variable $try +1.
You should initialize it at least to 0 first.

My code sometimes give code undefinet offset error.

This is the part of the code

$BuildEndTime = $CurrentQueue[$QueueID - 2][3];
unset($CurrentQueue[$QueueID - 1]);
$NewQueueArray = array();

I read lot of articles about this kind of errors but i do not know how to fix my code. Can someone help me please ?
You are trying to play with indexes that you are not sure they even exist...
things like
$CurrentQueue[$QueueID - 2]
is a guess... Get to find another way..
In this piece of code $CurrentQueue[$QueueID - 2][0], the key is generated dynamically based on $QueueID. WHen you get the error, it means that the specified key is not available in the array $CurrentQueue.
To avoid such run time exceptions, you can do something like this
if (!empty($CurrentQueue[$QueueID - 2])) {
// the actual functionality goes here.
}
I'm getting this error and after checking for similar errors I verified the syntax is correct. The complete error is;
WRITE OK
READ OK
Notice: Undefined variable: dbRead in C:\vhosts\phpcs5\lesson07\workfiles\scripts\user_registration.php on line 28
Fatal error: Call to a member function quoteInto() on a non-object in C:\vhosts\phpcs5\lesson07\workfiles\scripts\user_registration.php on line 28
My connection is defined as:
$dbwrite = new Zend_Db_Adapter_Pdo_Mysql($write);
$dbread = new Zend_Db_Adapter_Pdo_Mysql($read);
I did a test first to make sure it can see the database which is what the Write OK and Read OK are as follows;
if ($dbwrite->getConnection()) {
echo 'WRITE OK<br/>';
}
if ($dbread->getConnection()) {
echo 'READ OK';
}
So I'm not sure why I'm getting this error.
dbRead is undefined. You've defined $dbread. Note the capitalization.
Look through your code base (particularly user_registration.php line 28) and switch all instances to one or the other.
Notice (8): Use of undefined constant inList - assumed 'inList' [CORE\Cake\Utility\ClassRegistry.php, line 168]
This notice has been bugging me for a while know, and I do not know how to fix it.. It was not really affecting my project earlier since its just a notice msg, but now, it is not letting me show an error message which I am trying to display to the user.
Iv got this function
public function validate_form(){
if($this->RequestHandler->isAjax()){
$this->request->data['Donor'][$this->params['form']['field']] = $this->params['form']['value'];
$this->Donor->set($this->data);
if($this->Donor->validates()){
$this->autoRender = FALSE;
}else{
$error = $this->Donor->validationErrors;
$this->set('error',$error[$this->params['form']['field']]);
}
}
}
The above is the action to which my post request submits to. Then it executes the following to display the error
if (error.length > 0) {
if ($('#name-notEmpty').length == 0) {
$('#DonorName').after('<div id="name-notEmpty" class="error-message">' + error + '</div>');
}
}else{
$('#name-notEmpty').remove();
}
The problem is that instead of the relevant error in my newly created div... I get that notice 8 from cake! Please if anyone knows why this is happening, I appreciate your aid on this one..
TLDR:
Do a project-wide find for 'inList' and find the spot where it either doesn't have quotes around it, or, if it's supposed to be a variable, is missing it's $.
Explanation:
You get that error when you try to use a PHP Constant that doesn't exist. Usually you're not actually TRYING to use a constant, but instead just forgot to wrap quotes around something or forgot to add the $ before a variable.
Examples:
$name = "Dave";
echo name; // <-- WOAH THERE, there is no Constant called name (missing $)
$people = array('Dave' => 'loves pizza');
echo $people[Dave]; // <-- WOAH THERE, no Constant called Dave (missing quotes)
Most likely somewhere else in your code you are using 'inList' as an array key but you don't have it quoted.
Example: $value = $myArray[inList];
It still works without quoting inList but it causes the notice message you're seeing.
trying to get every post and comment from a facebook page, I made this function that should go through the pagination:
$req = $facebook->api("/" . $pagename . "/?fields=posts.fields(message,link,created_time,shares,likes,comments)");
function parcours_arbre($ab)
{
GLOBAL $facebook;
GLOBAL $pagename;
$next = create_request($ab['posts']['paging']['next']);
$next_req = $facebook->api($pagename.$next);
$ab_next = $next_req['data'];
$prev = create_request($ab['posts']['paging']['previous']);
$prev_req = $facebook->api($prev);
$ab_prev = $prev_req['data'];
if (empty($ab)) {
display_results($ab['posts']['data']);
} else {
parcours_arbre($ab_next);
parcours_arbre($ab_prev);
}
}
I unfortunately get the following error:
Notice: Undefined index: posts in /form.php on line 36
Notice: Undefined offset: 3 in /utils.php on line 20
Notice: Undefined offset: 4 in /utils.php on line 20
Fatal error: Uncaught GraphMethodException: Unsupported get request. thrown in /sdk/src/base_facebook.php on line 1271
Any idea how i could avoid it or what is going on? Would this go away if i use the "until" statement in my api request?
Thanks a lot,
To explain each error
the variable $ab which is an argument to the function, does not have a "posts" index. You should try to var_dump this variable so you can see what it actually looks like.
same as above
same as above
the api function takes 3. The path which should just be #pagename. The method ("GET" or "POST") most likely POST because GET is causing an error. The parameters, which should be array("fields" => "posts.fields(message,link,created_time,shares,likes,comments)")
I noticed that for next you have the code
$next_req = $facebook->api($pagename.$next);
but for previous you have
$prev_req = $facebook->api($prev);
Might want to look into this.
I want get from database table row name but in it i get error. ($query->code_airline => is other query as select from database table row)
code:
<?=$this->db->get_where('ticket_code', array( 'code' => $query->code_airline ))->row()->name?>
error:
A PHP Error was encountered Severity: Notice Message: Trying
to get property of non-object Filename: core/Loader.php(679) :
eval()'d code Line Number: 48
If want use it as:
<?php //This is line 49
$ca = echo $query->code_airline;
$query_tc = $this->db->get_where('ticket_code', array( 'code' => $ca ))->row();
echo $query_tc->name;
?>
have this error:
Parse error: syntax error, unexpected T_ECHO in
D:\xampp\htdocs\system\core\Loader.php(679) : eval()'d code on line 49
How can fix it?
Update:
i use as:
<?php
$ca = $query->code_airline;
$query_tc = $this->db->get_where('ticket_code',array('code'=>$ca));
$row = $query_tc->row(); //This is line 52
echo $row->name;
?>
i have this error with above php code:
A PHP Error was encountered Severity: Notice Message: Trying
to get property of non-object Filename: core/Loader.php(679) :
eval()'d code Line Number: 52
You don't ECHO in a variable assignment
$ca = $query->code_airline; //no echo here!
Also, I believe you're doing something wrong in calling $query->code_airline, but you didn't provide your code so I'm just guessing.
Suggestion: chaining is a nice feature but can be confusing, especially if written as one-liner. First of all, write it in full, you can "compact" your code later if you feel so; keep in mind readability and maintenability also:
$query_tc = $this->db->get_where('ticket_code',array('code'=>$ca));
// $ca is the value assigned above. Make sure you're calling $query->code_airline correctly, as per my suggestion.
$row = $query_tc->row();
echo $row->name;
UPDATE:
you might want to be sure that there are actually any result.
$query_tc = $this->db->get_where('ticket_code',array('code'=>$ca));
// $ca is the value assigned above. Make sure you're calling $query->code_airline correctly, as per my suggestion.
if ($query_tc->num_rows() > 0)
{
$row = $query_tc->row();
echo $row->name;
}
else
{
//do something else
}
