PHP - Input In Form Returns A String Instead Of Php Function

Hello


I am on to OOP now and I dont know how to write the syntax to print the results I want

The scenario is I have the abstract class, its subclass and then the object that calls the subclass, all in different files.

So:

part of the subclass reads:

Code: [Select]

function __construct($v1, $v2, $v3) {

$this->speed[] = $v1;  // I dont like this either, it is not elegant. I tried to put an array as argument of the constructor and send the parameters
$this->speed[] = $v2;  // from the object being created, but it did not work, so I leave it like this for now, but I would have preferred to put that
$this->speed[] = $v3;  // array and then populate it by some looping.

}

// METHOD TO REPORT TABLE OF ACCELERATION


   public function acceleration() {

   return $this->acceleration1 = ($this->speed[1] - $this->speed[0])/5;

          // I actually need to return the other two speed differences from the other stages, but as you know, once the first return acts, it exits the function
         // so sure this "return" has to be abandoned and the results of the function have to be printed otherwise. That is the question.

   }


===================================
And now from the Object file I am trying to call the function, but of course, I only get one value, even if I write 3 times return

Code: [Select]

$objeto = new Motorbike($v1, $v2, $v3);

echo '<p>The speeds are  ' . $objeto->acceleration() . '</p>';  // Yes, this call works, of course, but that is about it. I cant print any other result.


Thanks a lot

I think it is unusual but i dont know to fix it.  when my computer clock shows 16: 13 hours , date() reuturns 10:43:16 . My systems time zone is +5.30 GMT.
how does date() subtracts 5.30 hrs from the system time?

I need to know which day of week was on particular date, so for example I would provide date lets say "Nov 22, 2010" formatted as needed and the function would return "Monday", is there a function in php to do that or how can it be done?

can anyone see the problem here

i am running php 5.3 on my server and GD seems to be enabled. and my host said it was probably something to do with the captcha files or script.

I have this function completely written in my class file that I am working on.  The point to this function is to be able to check the login of a user or administrator for either of the control panels associated with my site.

It will check the session intime as well as the page / module referenced.  Once it passes all those checks, it will check and ensure the emailaddress/password stored in the current session still holds true and the account is still active...  if the account is still active it will update the lastActivity as well as update all of the session variables with what is currently in the database.

What I am looking for is basically a look at the function, see if it looks good..  If there is any part to it that could create security holes for the site just off the login function itself...

Usage: $q->validUser($_SESSION['user'], $_mod);

<?php
 function validUser($sess, $p) {

if ($sess['inTime'] == '' && $p != 'login' && $p != 'logout') {
session_destroy();
$login = '0';
$_int = '';
return $login;
} else if ($sess['inTime'] < time()-3600 && $p != 'login') {
$sess['inTime'] = '';
session_destroy();
$this->check_login($sess, $p);
} else {
$this->user = $sess['emailAddress'];
$this->pass = $sess['password'];

$login = $this->sql_query("SELECT * FROM users WHERE emailAddress = '".$this->user."' AND password = '".$this->pass."' 
   AND status = '1' LIMIT '1'");
if ($login = $this->sql_numrows($login) < 1) {
$sess['inTime'] == '';
session_destroy();
$login = '0';
} else {
// logged in, lets update the database for last_activity AND the session.

$this->sql_query("UDATE users SET lastActivity = '".now()."' WHERE
  emailAddress = '".$this->user."'");
$login = $this->sql_query("SELECT * FROM users WHERE emailAddress = '".$this->user."' AND password = '".$this->pass."' 
       AND status = '1' LIMIT '1'");
$login = mysql_fetch_assoc($login);
foreach ($login as $key => $value)
{ 
$sess[$key] = $value;
}
$sess['inTime'] = time();
$login = '1';
}
return $login;
}
}

?>

That is the main function, sql_query and sql_numrows is:

<?php
function sql_query($query = "", $transaction = FALSE) {
unset($this->query_result);

if ($query != "") {
$this->num_queries++;
if ($transation == BEGIN_TRANSACTION && !$this->in_transation) {
$result = mysql_query("BEGIN", $this->db_connect_id);
if (!$result) {
return false;
}
$this->in_transaction = TRUE;
}

$this->query_result = mysql_query($query, $this->db_connect_id);
} else {
if ($transaction == END_TRANSACTION && $this->in_transaction ) {
$result = mysql_query("COMMIT", $this->db_connect_id);
}
}
if ($this->query_result) {
unset($this->row[$this->query_result]);
unset($this->rowset[$this->query_result]);

if ($transaction == END_TRANSACTION && $this->in_transaction ) {
$this->in_transaction = FALSE;
if (!mysql_query("COMMIT", $this->db_connect_id)) {
mysql_query("ROLLBACK", $this->db_connect_id);
return false;
}
}
return $this->query_result;
} else {
if ($this->in_transaction ) {
mysql_query("ROLLBACK", $this->db_connect_id);
$this->in_transaction = FALSE;
}
return false;
}
}

function sql_numrows($query_id = 0) {
if(!$query_id) {
$query_id = $this->query_result;
}
return ($query_id) ? mysql_num_rows($query_id) : false;
} ?>

Any insight that can help to benefit these functions would be appreciated.

The dreadful apostrophie problem... This search form returns an error whenever searching with an apostrophie (')

Here's the code on the form (html)

and heres the code on srch_advert.php


if ($search)   // perform search only if a string was entered.
   {
    mysql_connect($host, $user, $pass) or die ("Problem connecting to Database");

What am i missing here why echo 0 == "some string" prints out 1?

Hello, I am attempting to create a script where a user puts a text string into a form and clicking on submit. Then it adds that text string to a mysql database and gives the user a link back to it. Something like mysite.com/key.php?id=4 and when going to that link it will display the text string from the database but printed in an image. I wrote something up but I cannot get it to work. I may be a little in over my head. Any help is appreciated.   The way I coded this all to work is the user inputs the information into index.php which givekey.php inserts that into the database. I have not yet figure out how to do this in one single step. After that I wanted it to navigate directly to key.php which would display the key and the link to that page with the ?key=XX attribute.
 
getkey.php

<?php
  require_once 'dbinfo.php';
  // database connection
 
  $id = $_GET['id'];
  // do some validation here to ensure id is safe
 
  $link = mysql_connect($servername, $username, $password);
  if (!$link) {
            die('Could not connect: ' . mysql_error());
            }
  @mysql_select_db($database) or die( "Unable to select database");
  $sql = "SELECT ukey FROM keycode WHERE id=$id";
  $result = mysql_query("$sql");
  $row = mysql_fetch_assoc($result);
  mysql_close($link);
 
  header("Content-type: image/png");
  echo $row['ukey'];
?>

Hi all dear
can anyone help me how to find all permutation of a String by allow user input text or number and generate when user click on button,

user need to input text on number in input box and click generate button to show result of all permutation of a String
below is code i found from https://www.journaldev.com/526/permutation-of-string-in-java
but it's not allow user input text,

please help me in php function
thank with best regard

 

<!DOCTYPE html>
<html>
<body>
<?php
function generatePermutation($string,$start,$end){ if($start == $end-1){ echo "$string - "; } else{ for($i = $start; $i < $end; $i++){ $temp = $string[$start]; $string[$start] = $string[$i]; $string[$i] = $temp; generatePermutation($string,$start+1,$end); $temp = $string[$start]; $string[$start] = $string[$i]; $string[$i] = $temp; } }
}
$str = "ABC";
$n = strlen($str);

I have a calendar select date function for my form that returns the date in the calendar format for USA: 02/16/2012.  I need to have this appear as is for the form and in the db for the 'record_date' column, but I need to format this date in mysql DATE format (2012-02-16) and submit it at the same time with another column name 'new_date' in the database in a hidden input field.  Is there a way to do this possibly with a temporary table or something?

Any ideas would be welcome.

Doug

I have read around and can't seem to find the right coding for what I need on this forum and some other other forums.

I have a contact form (as listed below) and I need 2 locations (Print Name and Title) fields to auto-populate on a separate form (can be a doc, pdf, etc. any form of document which is easiest) and this form can be totally back end and the individual using the form never is going to see the form.

It's going on a contract form, that we would like to auto-populate.

Also is there a simple attachment code so individuals can attach documents to the code?

Hey guys! I know there are a lot of topics about this, but mine is a bit different. I am creating my first contact form with php and I ran across this error after twinking with the php file:
Fatal error: Function name must be a string in /www/zymichost.com/m/t/l/mtlproductions/htdocs/Contact2.php on line 11
Here is what my code looks like currently:
Code: [Select]

<?php if ($missing || $errors) { ?>
<p class="warning">You did not enter the required information. Please try again.</p>
<?php }; ?>
<?php
($errors);

if ($isset($_POST['send'])) {

$subject = 'New Feedback Received on MikeyTateLive Productions website';
}
$expected = array('name', 'email', 'comments');

I originally had lines 9 and 10 set up like this except for the php opening and closing tags, lol:
Code: [Select]
<?php
$errors();
$missing();
?>

But as you can see on my full code at lines 9 and 10, I made a minor change to it and now the error comes from line 11 instead of 9 and 10. And now I could use some help with this.....

Thanks in advance for help.
I have a PHP script that has a function called traverseXMLNodes and it passes an xml string. I want anyone with a username and password to be able to call this function from his website or application or programming. In short i want my site to act as an API(Application Programming Interface).

 I am really stuck as to how to go about this. There are other functions i would like to call as well so traverseXMLNodes  is not the only function i want to my "API" users to access.

Below is the code I am using. the filename for my php i called remote.php. I am using the following query string to test and no results are returned.
http://localhost/testfolder/remote.php?xmlstring=20


Code: [Select]
<?php
$allowedfuncs = array('xmlstring','remotefunction2');
 
if(in_array($_get['xmlstring'], $allowedfuncs))
{
    $func = $_get['xmlstring'];
    $output = traverseXMLNodes($func);        // This calls $_get['funccall']()
    echo $output;
}
else
{
    exit();
}
 
 function traverseXMLNodes ($func) {
 
 echo "The XML string is";
 echo "<br/>";
 echo $func;
 echo "<br/>";
 }
/*
More functions go here
*/
?>

Hi I'm setting up my own framework for a project. I was coming to the point of completion and thought up of a new idea.

Is it possible to call a function like this from a class:


class myClass {

    function func($param)
    {
        echo "Hello world". $param;
    }

}

$class = 'myClass';
$func = "func(' It\'s time to partey!')";

$$class = new $class;
$$class->$func;


Thanks for any help!
