Re: dynamic page creation using php

I would suggest reading the source code of that or a similar project to get an idea of the scope of this project, how to lay it out and ball park the time you will need to devote to it.

My first suggestion would be that you DO NOT YELL! For many people there will be a perceived inference that they are not intelligent enough to identify important parts of the question..

My second suggestion would be to do as one always does when programming, and break the problem up into a number of smaller steps/chunks. In essence, the concept is really quite simple:

1) Implement access control system - i.e password=correct, pass=true. password=incorrect, pass=false
2) Devise a way of storing page data in a database
3) Implement a way of adding user-entered text into the database tables used in step 2

None of these 3 steps necessarily need to be complicated in order to provide basic functionality.
I'd expect to be able to bash out some code that would allow me to dynamically add page content if my password was correct in a few hours.

The polishing, refining and adding of other expected features are what I expect to take the absolute bulk of the time.

It's only 1/2 a Mb, why not download the code and take a look at it? You do get all the source code after all.

I've gleaned dozens of tips from the old game engines wolf3d, doom, quake, etc. Yet I've not copy/pasted a single line of code from any of them. Humans 'progress' because we are able to build-upon and extend the work of others..

Is there any free solution for voice recording in php?

insert multiple database table row from dynamic checkboxes from db

17-Aug-11 9:39

You will need to find out for yourself. Try running that google query with free tossed in. Otherwise just start looking through the results you get from google. This will als o giv you a basic idea as to how they did it, like what tools or language features did they use.

best of luck!

hello there

  `lid` int(5) NOT NULL,
  `gradeid` int(1) NOT NULL,
  
  PRIMARY KEY (`lid`,`gradeid`)
) ENGINE=MyISAM ;

GRADE

                          </form>
</body>
</html>

i want to make a TABLE ROW in TERM_LESSON for every checkboxes that is selected by user with same LID in form like: (for 2 chekbox seledted)

lid gradeid
11 , 1
11 , 2

and this is my php code for doing that:

PHP

<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
	
  foreach ($_POST['gradeid'] as $i) {

  $insertSQL = sprintf("INSERT INTO term_lesson (lid, gradeid) VALUES (%s, %s)",
                       GetSQLValueString($_POST['lid'], "int"),
                       GetSQLValueString($i, "int"));

  mysql_select_db($database_register, $register);
  $Result1 = mysql_query($insertSQL, $register) or die(mysql_error());
  }
  $insertGoTo = "lesson_term_added.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
    $insertGoTo .= $_SERVER['QUERY_STRING'];
  }
  header(sprintf("Location: %s", $insertGoTo));
}

mysql_select_db($database_register, $register);
$query_rstotalgrade = "SELECT * FROM grade";
$rstotalgrade = mysql_query($query_rstotalgrade, $register) or die(mysql_error());
$row_rstotalgrade = mysql_fetch_assoc($rstotalgrade);
$totalRows_rstotalgrade = mysql_num_rows($rstotalgrade);
?>

but when i submit the form i face to this error :

That is interesting.......

if you have experience with other programming language, i think you can start learning php.

If you dont know any other programming language, i am sure you are going to be slow.

You can collect a book. I started learning PHP reading a book published by Wrox publications. written bye 4 writer. i dont remember the name.

And about being professional?: start career as trainee somewhere. If you have the quality to be a programmer you will be.

Otherwise without real work there is no way being professional

php and mysql related firefox problem

16-Aug-11 11:08

look at the source code for some open source php projects. As a programmer you are going to read a lot of code, but if you can understand why the programmer designed the app the way he did you will gain quite a bit of info.

The fact is your browser doesn't execute your query twice. your php/html code has an mistake. different browser handle your mistake html code differently. may be that is why you are seeing result twice.

read your returned code.

Better is post your php code

i am posting my mysql query check it if you find any problem?

$sql_item=mysql_query("select * from add_out_stock where challan_no='$challan_no'");

while($rs=mysql_fetch_array($sql_item))
{

 $cata_name=$rs['catalogue_name'];


 $design_no=$rs['design_no'];


$qty=$rs['quantity'];



  $sql_stock=mysql_fetch_array(mysql_query("select * from  stock where catalogue_name='$cata_name' AND design_no ='$design_no'"));


   $tqty=$sql_stock['roll_no']-$qty;


 $qty= mysql_query("update stock set roll_no='$tqty' where catalogue_name='$cata_name' AND design_no ='$design_no'");



}

when i am using this code it executing $qty two times

If your SQL code is getting run twice for a particular browser but not others, you need to find out how many HTTP requests and responses are sent. LiveHTTPHeaders is a Firefox plugin, so can't see what happens on other browsers. Wireshark is independent of the browser, so it provides an impartial record of the HTTP traffic. If there is one request/response when it fails, then the problem is on the server side. If there are two, then you need to find out what is causing the second one. Javascript/JQuery in the browser, maybe?
