Hello i am new to this forum and coding. I am trying to fix a auto torrent downloading script which is php and curl.

?>

on the config file i have the varible it is refering too:

Code: [Select]
<?php
$layout = $url . "layout/";
?>

the actual file i get the error on (library.php)
Code: [Select]
<?php

class library extends core {

}
}

$obj = new library;


?>

is there a way to make it so it $layout works on any page or file as long as its in the includes?

thanks again.

Hi

I am buidling a Blog System using OO techniques (or at least attempting to)..

I keep getting an error :

Notice: Undefined variable: blog_categoryName in C:\wamp\www\atkinsonsCMS\admin170976\blog_categories.php on line 13
...And then underneath all that is is displaying 'Call Stack'. I've never come across this notification before so I guess it is an OO term, and the a list of unexpected outputs: #, time, memory, function and location....each with an associated value.
I attempted to resolve the variable issue in the usual way (as you can see in my code), but still the errors/warnings persist.

The purpose of this part of the code is to simply retrieve SQL data (which is a list of blog categories), allowing the user to select one and then click through to be directed to the appropriate category page (although this last requirement of the code has not yet been programmed).

Could those who have experience of this please take a look at my code and let me know where I am going wrong?

Thanks

blog_categories.php
This file calls on the the blogFunctions.php Category Class, and the displays the results.


session_start();
$pageTitle = "Blog Categories";
include("../includes/admin_header.php");
include("../classes/blogFunctions.php");
echo '<div class="admin_main_body"><br /><br />';
echo "<h2>Category List</h2><br />";
$content = new Category;
$content -> process();
//print_r(debug_backtrace());
echo "<a href=blog.php>$blog_categoryName</a>";
echo '</div>';
echo '</div>';
include("../includes/admin_footer.php");




blogFunctions.php
This class deals with the retreaval of the SQL data, and then passes it to blog_categories.php

I have a php page that is trying to pass a variable like this:

echo "<tr><td bgcolor='white'>" . $company_id . "</td><td bgcolor='white'><a href='companyusers.php?name=" . $company_name . "'>" . $company_name . "</a></td><td bgcolor='white'>" . $company_email . "</td><td bgcolor='white'>" . $company_status . "</td></tr>";

Then when some one clicks on that link they variable with it's value should go with the url and I'm trying to assign a variable like this:

$company_name = $_POST['name'];

It is not working!!! I get that "Notice: Undefined index: name in 'directory of page' on line 100"

Can someone help please?

I am new to php and html, I am trying to make a search function where you can search by a persons firstname or lastname but I am getting an error. the error is Notice: Undefined variable: searchq in C:\wamp\www\search2.php on line 17. Can anyone help me please

I just moved my code from Appserv to EasyPHP and it gave me this error, it was working fine on Appserv...what's with easyPHP ??

I have 2 issues happening, first one I need to get resolved is, line 60 is giving me a 'Notice: Undefined variable: delete'. This codes had multi issues but was able to resolve all but this one and my table not filling in with the data from my database. If you need any other info please let me know, Again I am new at this.                           <tr>
                        <td colspan="5" align="center" bgcolor="#FFFFFF"><input name="delete" type="submit"                         id="delete value="delete"></td>
                       </tr>                          <?php

                        // Check if delete button active, start this
*line 60* -----> if ($delete){
                       for($i=0;$i<$count;$i++){
                       $del_id = $checkbox[$i];
                       $sql = "DELETE FROM $tbl_name WHERE id='$del_id'";
                       $result = mysqli_query($sql);
                       }

                        // if successful redirect to delete_multiple.php
                       if($result){
                       echo "<meta http-equiv=\"refresh\" content=\"0;URL=delete_multiple.php\">";
                        }
                        }
                        mysqli_close($con);
                        ?>

First let me explain my code.
It comprises of three php files.

inc_fn_header_and_menu.php,  contains the HTML and CSS header details and it initializes the session via session_start();

 

This  is later included in project_status.php] .

 

In project_status.php] , I have included another file project_status_app.php which contains a HTML form.

 project_status.php:

<?php
 include 'inc_fn_header_and_menu.php';
function includeFile($file,$variable) {
    $var = $variable;
    include($file);
}
if (isset($_GET['id']) && $_GET['id']!="") {
    $pid    = $_GET['id'];
    $_SESSION['pidForApproval'] = $_GET['id'];
    $query = 'SELECT * FROM `profile` WHERE pid ='.'\''.$pid.'\'';
    $result=mysqli_query($db,$queryToRetrievePP) or die("There are no records to display ... \n" . mysqli_error());
    foreach ($result as $row) {
        $status = $row['status'];
    }        
}
...........some PHP and HTML code.......
	<div id="customerPurchaseApprovalForm">
<?php  
  echo '<p>APPROVAL FOR CUSTOMER PURCHASE</p>';
  $discountApprovalStatus = "Granted";
  if ($discountApprovalStatus == "Granted") {  
 
  includeFile("project_status_app.php",$highestannualvalue);
  } else {
     //.........
  }

In project_status_app.php I am attempting to retrieve pidForApproval from the $_SESSION array.

<?php
        // put your code here  UPDATE `pp` SET `customer_purchase_remarks` = 'hahaha' WHERE `pp`.`id` = 207;
        
        if ($_SERVER['REQUEST_METHOD'] == 'POST') {
            include '../../inc/fastlogin.php';      
            $sql = "UPDATE pp SET customer_purchase_remarks ='{$_POST['remarkstxt']}' WHERE pp.pid='{$_SESSION['pidForApproval']}'"; 
            $result = mysqli_query ( $fastdb, $sql ) ;
            if (mysqli_affected_rows($fastdb) != 1) { 
               $_SESSION['err_cpa_rmks'] = "<p>Error while updating WHERE id='{$_SESSION['pidForApproval']}'</p>";
                //echo "<p>Error while updating WHERE id='{$_POST['pidForApproval']}'</p>".mysqli_error($fastdb);                 
            } else { 
                $_SESSION['suc_cpa_rmks'] = "<p>Records was updated successfully.</p>";
                //echo "Records was updated successfully."; 
            }
            header ("location: project_status.php?id="$_SESSION['pidForApproval']);
            exit();
        }    
        
        ?>

When I load  project_status.php,  project_status_app.php is supposed to display the form. Once the user fills in the form the and the submit button has been pressed, the UPDATE statement is supposed to run and then it is supposed to navigate back to project_status.php?id=FA142. But the update is failing and the when the project_status.php is loaded back, the url looks like this http://localhost/fast/project_status.php?id= . The id is empty. It is supposed to be something like this http://localhost/fast/project_status.php?id=FA142. With the id being populated at the 

header ("location: project_status.php?id=".$_SESSION['pidForApproval']);

I suspected that my $_SESSION['pidForApproval'] is not being populated in project_status.php but I echoed back $_SESSION['pidForApproval'] in that file itself and I can see it is being populated. Hence, I suspect that the $_SESSION['pidForApproval'] is not being passed to project_status_app.php. I have already attempted to include session_start(); clause in project_status_app.php but that gives an error, stating that the session has already started, in inc_fn_header_and_menu.php. Can someone help me as to why the $_SESSION['pidForApproval'] is not being passed on to the project_status_app.php file. Thank you.

What can I do to fix this? I'm told that variable don't need to be defined before being initialized, but that doesn't really mean much to me!
Please help

while i am coding to find text between some html tags ,,
am getting an error...
Notice: Undefined offset: 1 in D:\xamp\xampp\htdocs\file\dash.php on line 48

Hi, I'm testing my PHP in the console and was wondering what this means?
PHP Notice: Undefined offset: 1
Is it a warning or an error?
My code...
Code: [Select]
$form_submission = "brother";
$lines = file('eo_dic.txt');

if ($form_submission == null){ // Sanitization.
echo 'Text field is empty!';
exit;
}
 
foreach ($lines as $line) {

list($field1, $field2) = preg_split('/=/', $line); // back slash might not be needed

  if (stristr($field1, $form_submission) || stristr($field2, $form_submission)){
echo $field1 . ' = ' . $field2;
}
}
The results and error...
Code: [Select]
Brother = frato
Brotherhood = frateco
Brotherly = frata
