PHP - Help With Connecting To Localhost

I have a Login Script with a Remember me Function. The Script works flawlessly on my local server but when I upload it doesn't work on my web server.

From what I can tell its a Session issue, When I log in, I make a session with the user ID, in which is used to pull all there information on other pages. On my local host it makes the sessions and everything is dandy, but on the web server it doesn't seem to make the session. 

Can anyone shed any light on this, I'm clueless once again ^_^

I've installed Drupal 7.1 on my computer and I'm trying to access it via localhost.  However, the site does not load the "index.php" file.  Instead, I get the list of files and folders in the working directory with the heading "Index of /drupal71" (drupal71 is the temporary site name).

The .htaccess file has the following lines, so I'm confused as to why index.php doesn't load automatically.
Code: [Select]
# Set the default handler.
DirectoryIndex index.php index.html index.htm
Any suggestions?

Hi, I still a noob in PHP programming I hope somebody in the forum can help me and give an ideas how to fixed to this problem,

everytime I run localhost this message appear:

ErrorException in Builder.php line 1023:count(): Parameter must be an array or an object that implements Countable

But if I type localhost/(anycharacter) the page appear but with error 404(kindly refer to image, all other buttons are working except the one indicated with the arrow( kindly refer on the last image, note: app_debug set to true), this problem keeps bugging me for a few weeks now that I still cannot find a way to fixed it. Thank you in advance.

)

 

this problem really drives me crazy..hope that anyone could help.

I left my page only with
<?php
session_start();
?>
with no script at all..and i still got error

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at E:\Program Files\XAMPP 1.5.4\xampp\htdocs\folder\page1.php:1) in E:\Program Files\XAMPP 1.5.4\xampp\htdocs\folder\page1.php on line 2

No white space at all. I tried to upload this file into the server (not local) and no error appeared. but when i run it in my local server, error appeared.

I restart my xampp so many times but still didn't fix this.

what's the problem then?

thanks in advance

Hi, would like to know if there is any way to send email using localhost? is it possible and how can i do it?

Hi everyone!

I am building an application in PHP with MySQL on my localhost. I tried to connect to the database like this:
mysql_connect("localhost", "root", "password");
mysql_select_db("app-db");

 but the message I get is:

Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'user'@'localhost' (using password: NO) in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\app\Source\includes\db_connect.php on line 3

Warning: mysql_select_db() [function.mysql-select-db]: Access denied for user 'ODBC'@'localhost' (using password: NO) in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\app\Source\includes\db_connect.php on line 4

Warning: mysql_select_db() [function.mysql-select-db]: A link to the server could not be established in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\app\Source\includes\db_connect.php on line 4

I never wrote user 'user' in the whole application but root and even when I comment out that line of mysql_connect, the first error doesn't go away.
The url of the index of the application is localhost/app/Source/index.php
When I make a page: localhost/index2.php with the same content as my db_connec file then there is no error. When I move or copy the db_connect file to localhost/db_connect.php it also gives me those warnings.
Also, when I change things in the code, PHP does not recognize them and nothing changes - meaning, that I can comment out those connect statements and still get the warnings.
Can anyone offer me some advice and help me solve this, please?

Thanks in advance!

Hi, folks --

I've been working on this for quite awhile, and have done lots of searching, but I still cannot make it work.  Using Xampp on Win 7 x64, with PHP 5.3.  Here is my simple PHP code just trying to get something to work:

$to      = 'my_real_email@gmail.com';  
$subject = 'the subject';
$message = 'hello';
$headers = 'From: someone@localhost.com' ;

mail($to, $subject, $message, $headers);
?>

(NOTE: "my_real_email" is set to my actual email address.)

Here are my php.ini settings:

Code: [Select]
[mail function]
; For Win32 only.
; http://php.net/smtp
SMTP = localhost
; http://php.net/smtp-port
smtp_port = 25

; For Win32 only.
; http://php.net/sendmail-from
; sendmail_from = postmaster@localhost

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").
; http://php.net/sendmail-path
sendmail_path = "\"E:\xampplite\sendmail\sendmail.exe\" -t"

; Force the addition of the specified parameters to be passed as extra parameters
; to the sendmail binary. These parameters will always replace the value of
; the 5th parameter to mail(), even in safe mode.
; mail.force_extra_parameters =

; Add X-PHP-Originating-Script: that will include uid of the script followed by the filename
mail.add_x_header = Off

; Log all mail() calls including the full path of the script, line #, to address and headers
mail.log = "E:\xampplite\apache\logs\php_mail.log"
I'm not getting an error and the email seems to be getting "logged", but I do not receive an actual email in my account.

Thanks for any suggestions.

$download will print on the screen on my localhost, but once I've uploaded it to my host and go to the website, everything else prints to the screen fine, but $download will not. When I view page source, shows nothing where $download should be.

$link_pattern = "/<tr><td><a(.*)<\/tr>/sU"; 

preg_match_all($link_pattern,$cr,$dm);
$downloads = $dm[0][0];
$pattern = '/src=\"/';
$replacement = 'src="http://www.triplestarent.com/images';
$download = preg_replace($pattern, $replacement, $downloads);

hello.

i want to create an oop website on my localhost but im having trouble getting the initialize file to find my config file.

if i point my browser to my local host my index page works fine because it does not need the initialize file at this stage, but if i point my browser to my admin index (http://localhost/djsonrotation/admin/) i get this error

Quote

Warning: require_once() [function.require-once]: URL file-access is disabled in the server configuration in /Applications/MAMP/htdocs/djsonrotation/includes/initialize.php on line 9

Warning: require_once(http://localhost/djsonrotation/config.php) [function.require-once]: failed to open stream: no suitable wrapper could be found in /Applications/MAMP/htdocs/djsonrotation/includes/initialize.php on line 9

Fatal error: require_once() [function.require]: Failed opening required 'http://localhost/djsonrotation/config.php' (include_path='.:/Applications/MAMP/htdocs/php5/lib/php') in /Applications/MAMP/htdocs/djsonrotation/includes/initialize.php on line 9





the initialize file is basically 1 place that points to lots of different places and mine looks like this:
Code: [Select]
<?PHP
defined('DS') ? null : define('DS', DIRECTORY_SEPARATOR);
defined('SITE_DOMAIN') ? null : define('SITE_DOMAIN', 'http://localhost/djsonrotation');
defined('SITE_ROOT') ? null : define('SITE_ROOT', $_SERVER['DOCUMENT_ROOT']);
defined('LIB_PATH') ? null : define('LIB_PATH', SITE_DOMAIN.DS.'includes');
defined('CSS_PATH') ? null : define('CSS_PATH', SITE_DOMAIN.DS.'css');

require_once(SITE_DOMAIN.DS.'config.php');
require_once(SITE_DOMAIN.DS."functions.php");
require_once(SITE_DOMAIN.DS."session.php");
require_once(SITE_DOMAIN.DS."database.php");
require_once(SITE_DOMAIN.DS."user.php");
?>

this is the config file its looking for:
Code: [Select]
<?PHP
defined('DB_SERVER') ? null : define("DB_SERVER", "localhost");
defined('DB_USER') ? null : define("DB_USER", "admin");
defined('DB_PASS') ? null : define("DB_PASS", "*************");
defined('DB_NAME') ? null : define("DB_NAME", "djsonrotation");
?>

this is how my mamp is set up
Quote

PORTS - 80  - 3306
PHP - 5
APACHE - /Applications/MAMP/htdocs




this is where my file are located on my wwwroot

/index.php
/includes/initialize.php
/includes/config.php
/admin/index.php


this is the line of code calling the initialize on /admin/index.php
Code: [Select]
require_once("../includes/initialize.php");

I have pretty much the same problem. I am just starting without any previous experience with xampp, php or MySQL, I have been coding in C for a few years and have used Java before. Just wanted to play with a local website design using a Joomla template as my method for learning php etc. I installed XAMPP 1.8.3 and then a Joomla template into htdocs. Xampp runs fine and I have localhost and other pages without issue. localhost/myphpadmin is blank. I have not yet created a DB as I cannot access myphpadmin and have no code yet either. The error reporting is set as you suggest but no errors are reported. For error_reporting I used a - 1, phpinfo shows it as 22527 while display_error is On   The source for the phpmyadmin is blank but using FF dev tools the error console shows: Error: The character encoding of the HTML document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the page must be declared in the document or in the transfer protocol.
Source File: http://localhost/phpmyadmin/   Also tried with Opera and IE I have installed Xampp on a USB drive labelled as V: as my SS C: drive has limited space. I installed the Java SDK as well (Version 8 update 20 build 1.8.0_20-b26 php is reported as 5.5.15 in xampp.   This all happened straight from install, so no editing of files by me. All I have edited since is the error entries in php.ini

Hi,

  I am trying to send mail from my localhost but i am getting the below error

please help me...

Thank You

Hi all

I am running XAMPP on my laptop and working with files not in the localhost directory.  For functions like fopen, there is no problem, I specify a path starting from the localhost directory to wherever I want to work and that's fine.

For some reason though, it is NOT working with IMG SRC.  I get my PHP to generate the following line of code :

<IMG SRC = "http://localhost/../../../wherever/android.jpg">
   
(which in this case points to C:\wherever\android.jpg)

However the browser misses the middle bit of the URL out and interprets it just as localhost/wherever/android.jpg - which clearly doesn't exist !

Likewise, if I try typing the address straight into the address bar, the '../../../' bit of it immediately vanishes.

I've tried formatting the URL in a variety of ways, none of them seem to work, where am I going wrong ?  Many thanks !

Hi,

I found a tutorial in building a poll, however it detects IP, so people can't vote multiple times, so I dissected the code into sections while removing the IP blocking, while still inserting the IP address into the database, the problem is that I get:

Access denied for user 'ODBC'@'localhost'

for the second page, I don't know where I went wrong, could anyone help me? I also attached the code and .sql file so that people can hack it and check where it got wrong.

Thanks

I have a CURL code that fetches some XML content from a remote server. I get the expected output on my localhost (XAMPP on windows). But from the live site(hosted on Linux), I get the CURL error:'couldn't connect to host'.

function DownloadUrl($Url, $p){
 
// is curl installed?
if (!function_exists('curl_init')){ 
die('CURL is not installed!');
}

       // create curl resource
        $ch = curl_init();

        // set url
        curl_setopt($ch, CURLOPT_URL, $Url);

   curl_setopt ($ch, CURLOPT_POSTFIELDS, $p);
   curl_setopt ($ch, CURLOPT_POST, 1);
        //return the transfer as a string
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

        // $output contains the output string
        $output = curl_exec($ch);
        
   if($output === false)
   echo 'Curl error: ' . curl_error($ch);
   else
     print $output;
        // close curl resource to free up system resources
        curl_close($ch);          
}
