PHP - Can Someone Provide Me With A Good Tutorial...

Dear All

           Good Day, i am new to PHP (a beautiful server side scripting language). i want to send a mail with line by line message i tried with different types like by placing the things in table and using  <br /> but the thing is the tags are also visible in the message of the mail.

Here is my code:

$message1  = "Name       :".  $_REQUEST['name']."<br />";
$message1 .= "Surname    :".  $_REQUEST['surname']."<br />";
$message1 .= "Cellphone  :".  $_REQUEST['mobileno']."<br />";
$message1 .= "Telephone  :".  $_REQUEST['landno']."<br />";
$message1 .= "Fax        :".  $_REQUEST['fax']."<br />";
$message1 .= "Company    :".  $_REQUEST['company']."<br />";
$message1 .= "Email      :".  $_REQUEST['email']."<br />";
$message1 .= "Country    :".  $_REQUEST['country']."<br />";
$message1 .= "Enquity    :".  $_REQUEST['enquiry']."<br />";
$message1 .= "Date&Time  :".  $date."<br />";

For this code if try to print/echo it it is working fine it is displaying line by line, but using this variable ($message1) in the mail these <br /> are also visible.
Can any one guide me to resolve(to remove these tags from the message part) this issue.
Thanks in Advance. :confused:

I followed the tutorial at http://www.devshed.com/c/a/PHP/Building-An-Extensible-Form-Validator-Class/ because I wanted to have an easier way to build and maintain form validation.
I completed the tutorial, but the form does not register the form as being filled out.
Here is the class code (FormValidator.class.inc)
<?php
//FormValidator.class.inc
//class to perform form validation
class FormValidator {

   //---------------private variables------------------

   var $_errorList;
   //the _ prefix is used to distinguish private variables from public variables

   //---------------methods (private)------------------
   
   //functio to get the value of a variable (field)
   function _getValue($field) {
      global ${$field}; //makes the field entry a global variable
      return ${$field};
   }

   //---------------methods (public)-------------------
   
   //it is a good idea to run resetErrorList() whenever the class is first initialized
   //PHP makes it possible to automatically execute a specific function when a new instance of a class is spawned. This function is referred to as a "constructor" and must have the same name as the class.
   //reset error list
   function FormValidator() {
      $this->resetErrorList();
   }
   
   
      //begin basic validation routines
      
   //check whether input is empty
      //the isEmpty public method is called with 2 arguments, one for the form variable and one for the error message
      //the method internally calls the _getValue method and then trim()s the result to check if it is empty
      // if the variable is empty, a new element is added class variable $_errorList (an array) to represent the error. This new element is itself a three-element associative array, with the keys "field", "value" and "msg", representing the form variable name, the current value of that variable, and the corresponding error message
      // if the variable is not empty, it will pass the test and return true
      // this function, along with _getValue, allows the user to get both the field name and the field value
      //the $this prefix provides a convenient way to access variables and functions which are "local" to the class.
   function isEmpty($field, $msg) {
      $value = $this->_getValue($field);
      if (trim($value) == "") {
         $this->_errorList[] = array("field" => $field, "value" => $value, "msg" => $msg);
         return false;
      }
      else {
         return true;
      }
   }
   
   //check whether input is a string
   function isString($field, $msg) {
      $value = $this->_getValue($field);
      if(!is_string($value)) {
         $this->_errorList[] = array("field" => $field, "value" => $value, "msg" => $msg);
         return false;
      }
      else {
         return true;

   function isNumber($field, $msg) {
      $value = $this->_getValue($field);
      if(!is_numeric($value)) {
         $this->_errorList[] = array("field" => $field, "value" => $value, "msg" => $msg);
         return false;
      }
      else {
         return true;
      }
   }
   
   //check whether input is an integer
   function isInteger($field, $msg) {
      $value = $this->_getValue($field);
      if(!is_integer($value)) {
         $this->_errorList[] = array("field" => $field, "value" => $value, "msg" => $msg);

   }
   
   //check whether input is within a valid numeric range
   function isWithinRange($field, $msg, $min, $max) {
      $value = $this->_getValue($field);
      if(!is_numeric($value) || $value < $min || $value > $max) {

Hello Php Freaks

I am following this tutorial how to make a login for my website, the only trouble is that... It dosen't seem to work, so i wanna know if its only me who cant make it work... and if it is why XD...

Tutorial can be found he
http://www.knowledgesutra.com/forums/topic/7887-php-simple-login-tutorial/


Now when i get started it starts saying error at line 6:
        if ($_GET["op"] == "login")

It says that when im about to login right above the login.

Now when i put in data i get error on line 19:

  $r = mysql_query($q);

That one, and i have no idea how to fix it.

Anyone please ?

I have a need to create a form that will get info from a mysql table, show that info, two fields one of which I want to be a checkbox that will need to update the table with either a 0 or a 1.  I will later use that info.  I have searched all over and haven't found what I am looking for.  I can find tutorials for creating checkboxes but nothing what I need / want

Hello,

I'm making a website which includes an articles page. I want users to be able to search for particular articles.
For this search function I used the Simple SQL Search tutorial from phpfreaks (http://www.phpfreaks.com/tutorial/simple-sql-search).
It's working quite well but i'd like to expand it a little. The most important thing i want changed is what happens when users enters a string which holds multiple words. The function from the tutorial perceives these words as one string and searches for that string as a whole. For example when a user enters 'winter 2012' and an article holds the string 'winter of 2012', the function returns no matches. This is, ofcourse, not the way i'd like it to function.

I've managed to seperate the words and search for them individually by using explode and foreach, but now i'm getting duplicate results when an article holds mulitple words from the users' entry string. My idea to fix this was to make an array with the article id's of the articles that have matched, and then to exclude them from the SQL query for the next word from the search string by using 'NOT IN $array' in the where clause.
Unfortunately i haven't managed to succeed with this so far and that's why i ask for your help..


This my search function:

Code: [Select]
function zoekopdracht() {
   require('dbcon.php');
   $zoekopdr = trim($_GET['zzoek']);
   $zoekopdr = strip_tags($zoekopdr);
   if (strlen($zoekopdr) < 3) {
      echo "De zoekopdr moet minimaal 3 karakters bevatten.";
   } else {
      $zoekopdr = explode(" ", $zoekopdr);
      foreach($zoekopdr as $zoekterm) {
         $zoekopdrDB = mysql_real_escape_string($zoekterm);
         $searchSQL = "SELECT * FROM n_artikelen WHERE ";
         $types = array();
         $types[] = isset($_GET['zartikel'])?" volledig_artikel LIKE '%{$zoekopdrDB}%'":'';
         $types[] = isset($_GET['ztitel'])?" titel LIKE '%{$zoekopdrDB}%'":'';
         $types[] = isset($_GET['zjaar'])?" YEAR(publicatie) LIKE '%{$zoekopdrDB}%'":'';     
         $types = array_filter($types, "removeEmpty"); // removes any item that was empty (not checked)     
         if (count($types) < 1) {
            $types[] = "volledig_artikel LIKE '%{$zoekopdrDB}%'";  // use the artikel + titel as a default search if none are checked
            $types[] = "titel LIKE '%{$zoekopdrDB}%'";
         }
         $searchSQL .= implode(" OR ", $types) . " ORDER BY publicatie LIMIT 0,10";
         $searchResult = mysql_query($searchSQL) or die(mysql_error());         
         if (mysql_num_rows($searchResult) < 1) {
            echo "De zoekopdracht '{$zoekopdr}' heeft geen resultaten.";   
         } else {
            while ($row = mysql_fetch_array($searchResult, MYSQL_NUM)) {
               artikelelement($row);   // function that outputs the result of $row[]
            }
         }
      }
   }   
}

Additionally, if this problem is fixed, i'd love to see a way to sort the results on closest match (article which matches two words > article which matches one word).


Thanks!

I am following a tutorial on how to make a simple PHP shopping cart at:
http://v3.thewatchmakerproject.com/journal/276/

I have discovered a problem with the code where a } is not closed.

Quote

$cart = $_SESSION['cart'];
if ($cart) {
$items = explode(',',$cart);
$contents = array();
foreach ($items as $item) {
$contents[$item] = (isset($contents[$item])) ? $contents[$item] + 1 : 1;
}


Should the } go on the end of the code or is it suppose to go else where within it?

I found this amazing tutorial and i try to change it for a different database, but when i do a search it never finds anything.
