PHP - Functions In Include File: Call To Undefined Function

What's undefined about deposit()?

Code: [Select]
class BankAccount {
private $name;
var $balance = 0;
private $dep = 0;

function __construct() {
if (array_key_exists ("deposit" , $_POST)) {
$dep = $_POST['deposit'];
echo $dep;
deposit($dep);
}
}

function deposit($dep) {
$balance += $dep;
echo $balance;
}
}

Currently, I am reading a book called PHP Web 2.0 Mashups and I have stumbled across an error on the second chapter which deals with XML-RPC protocol. The book has the following code which it uses to demonstrate the XML-RPC encoding functionality of PHP with the xmlrpc_encode_request function:


<?php
$singleVar = "Hello!";
$requestMessage = xmlrpc_encode_request('theRemoteCall', $singleVar);
echo $requestMessage;
?>


However when I load this page up on my local testing platform nothing is displayed. Upon checking the PHP error log I am confronted with this:

[24-Jan-2011 07:56:40] PHP Fatal error:  Call to undefined function xmlrpc_encode_request() in C:\wamp\www\jquery\collapsible.php on line 79

A couple of other points in relation to this:

1. I have the following lines in my PHP.ini file:

Code: [Select]
; Turn off normal error reporting and emit XML-RPC error XML
; http://php.net/xmlrpc-errors
;xmlrpc_errors = 0

; An XML-RPC faultCode
;xmlrpc_error_number = 0
Does this not mean that xmlrpc functions are all ready installed on my WAMP server? I have download XML-RPC for PHP from http://phpxmlrpc.sourceforge.net/ (3.0.0 beta) and placed the files inside the extracted 'lib' folder into C:/PHP/includes and uncommented the PHP.ini line 'include_path = ".;c:\php\includes"'.

However still, after restarting WAMP and refreshing the page it is still issuing a fatal error in PHP error log.

Thank you for all your help in advance.

Hi all

I have been trying to do a query but I get

Call to undefined function mysql_connect()

What other way can I perform a query? Or do I need to get something enabled?

Thank in advance

I have a file I'm trying to split up to separate some HTML from PHP code. Everything works fine when all of the code is together but when I split it into two files the two call back functions in the html form will not work. No errors and when I view the page source my file is included with the form. Any help would be appreciated.
Here is the file that has the include statement.
add_action('admin_menu', 'sampleoptions_add_page_fn');
// Add sub page to the Settings Menu
function sampleoptions_add_page_fn() {
    add_options_page('Options Example Page', 'Options Example', 'administrator', __FILE__, 'options_page_fn');
}
function options_page_fn() {
?>
<?php include('options_form.php'); ?>
<?php
}

Here is the options_form.php file code.
Code: [Select]
<div class="wrap">
        <div class="icon32" id="icon-options-general"><br></div>
        <h2>My Example Options Page</h2>
        Some optional text here explaining the overall purpose of the options and what they relate to etc.
        <form action="options.php" method="post">
        <?php settings_fields('plugin_options'); ?>
        <?php do_settings_sections(__FILE__); ?>
        <p class="submit">
            <input name="Submit" type="submit" class="button-primary" value="<?php esc_attr_e('Save Changes'); ?>" />
        </p>
        </form>
    </div>
I'm guessing that it may have to do with this line of code, due to the page parameter but I don't know that much about that area.
<?php do_settings_sections(__FILE__); ?>
Thanks in advance

Something strange is happning, line producing the error:

if( ($this->subject == "") || ($this->message == "") ){


Any ideas guys?

thanks lots!!

Hello,

i use MySQL with PHP.
My php version is 5.2.0.
After i connect to the db i use mysql_set_charset in order to change the system variables (character_set_client , character_set_results ,character_set_connection).
i do:

Code: [Select]
if (USE_PCONNECT == 'true') {
      $$link = mysql_pconnect($server, $username, $password);
      mysql_set_charset('utf8',$$link);
      } else {
      $$link = mysql_connect($server, $username, $password);
      mysql_set_charset('utf8',$$link); 
    }
I take the error: Fatal error: Call to undefined function mysql_set_charset().

In the manual page for mysql_set_character says:
1."(PHP 5 >= 5.2.3)" --> that means that i have an old php version??
2."Note: This is the preferred way to change the charset. Using mysql_query() to execute SET NAMES .. is not recommended. "

What shall i do in order to solve my problem??

thanks, in advance!

I am using tidy_repair_string() function as part of a string filter, the except is below.

/* Tell Tidy to produce XHTML */
		$xhtml = tidy_repair_string($html, array('output-xhtml' => true));

I am getting a fatal error thrown up as below. I thought tidy_repair_string() is an inbuilt PHP function or is it not?

Fatal error: Call to undefined function tidy_repair_string() in C:\wamp\www\APPLICATION-FOLDER\contituency-manager\filter.php on line 14

I keep getting this error and can not figure out what is wrong:
Fatal error: Call to undefined function showcart() in C:\xampp\htdocs\sas\shoppingcart\showcart.php on line 8

I have attached both the showcart.php and the functions.php files

any help will be appreciated

Thank you
John

when I try to upload the image on submit, I get there following error:

Fatal error: Call to undefined function file_extension() in editlogo.php on line 41

  $img_name = $_FILES['myimage']['name'];
        $tmp_name = $_FILES['myimage']['tmp_name'];
        $img_size = $_FILES['myimage']['size'];
       
        if ($img_name) {

my supervisor said that i have a library to add.. im searching on it but i cant find anything..
help pls..

i run this on linux.

I have a long list of variables with form fields inserted into them like this:


$page_id = $_POST['exclude'];


I just turned on WP_Debug just to see which error messages would come up and to my surprise it wasn't that bad, the most error messages were "Call to Undefined function".

The solution to this problem is simple, all I  have to do is wrap an isset around all the form field variables, like this:


$page_id = isset($_POST['exclude']);


My question is, is this really necessary or considered as good practice? Should I now go ahead and wrap to all the variables in that long list an isset around?

Or should I just turn WP_Debug off again and leave it as is?

I personally would like to adopt to the good practice way, but I don't know how much of an advantage it is to wrap an isset around every single form field variable.

Any suggestions?

Hello,
   I have the situation shown below in the code:

if(//condition is met)
{ $val = new Val();
  $valon = $val->check($_POST, array(.........));
}
if($valon->passes())
{ $use = new Use();
  ........
}
//check() and passes() both belong to class Val
public function check($source, $items = array())
{ ......................
  return $this;
}

I get the following warning and error:

Notice: Undefined variable: valon
and
Fatal error: Call to a member function passes() on a non-object

I can't see anything wrong with the code. check() returns an object of class Val which is assigned to $valon, $valon then calls a member function of class Val. Could you please help. Please let me know whether to include further code.

MySQL Client Version: 5.1.50-community
PHP Version: 5.3.5
Apache Version: 2.2.17

Okay, I am trying to get MySQL to cooperate with PHP. All of my attempts have been unsuccessful.
Before you post a reply, please note I have taken these steps before I posted this topic:
1. My libmySQL.dll is in both my php and C:\Windows folder
2a. (Mental note: my installation directory is C:\Program Files\Apache 2.2\php\ext)
2b. The extension_dir in my php.ini file is as follows: Code: [Select]
extension_dir = "C:\Program Files\Apache 2.2\php\ext"3. The php.ini file is also in the C:\Windows folder.
4. The extensions that are enabled for php are as follows: Code: [Select]
[PHP_MYSQL]
extension=php_mysql.dll
[PHP_MYSQLI]
extension=php_mysqli.dll
[PHP_PDO_MYSQL]
extension=php_pdo_mysql.dll5. Any section referencing to MySQL in my php info is not showing up.
6. I have tried replacing my php_mysql.dll, didn't work either.

Okay, so when I try to install my forums for my website, it returns with this error: Fatal error: Call to undefined function mysql_connect() in C:\Program Files\Apache 2.2\htdocs\forum\upload\includes\class_core.php on line 312
Please notify me of anything that has or will work(ed).

After I did enable the following error reporting:

Code: [Select]
   Default Value: E_ALL & ~E_NOTICE
I am getting the error message described in the title of this thread.

I do have the php_mysqli.dll extension enabled as well - AND the function used to work as is, before I changed the error reporting, thus the function actually should be defined, what could be another reason, that PHP thinks it is not a defined function?
