PHP - New To Php A Few Questions Plase

hey everyone!

I Need an update data code from a form.

First of all I need a list which shows all the rows from my database. then when user select the row which he/she want to edit, he/she can be able to fill the form and when enters the update button that row should be updated.

Can anyone help me how to do such thing.

I would really appreciate it.

Hi,
I am trying to build a search function and so far I have it working with just one DB field but I need it to search for different fields.

This is my search form:

Code: [Select]
<form action="t_articulo_Results.php" method="get" name="SearchForm" id="SearchForm">
          <label>
            <input type="text" name="S_articulo_esp" id="S_articulo_esp" value="search" size="30" />
             <input type="hidden" name="Search" id="Search" value="Buscar" />
            </label>
          </form>
where the field "S_articulo_esp" is a text field to enter the search criteria.

This is the code on my results page inclung query:

Code: [Select]
<?php 

$MySearch_DefaultWhere = "";
if (!session_id()) session_start();
if ((isset($_GET["Search"]) && $_GET["Search"] != "")) {
  $MySearch = new FilterDef;
  $MySearch->initializeQueryBuilder("MYSQL","1");
  //keyword array declarations

  //comparison list additions
  $MySearch->addComparisonFromEdit("company_name","S_articulo_esp","AND","Includes",0);

  //save the query in a session variable
  if (1 == 1) {
    $_SESSION["MySearch_t_articulo_Results"]=$MySearch->whereClause;
  }
}
else     {
  $MySearch = new FilterDef;
  $MySearch->initializeQueryBuilder("MYSQL","1");
  //get the filter definition from a session variable
  if (1 == 1)     {
    if (isset($_SESSION["MySearch_t_articulo_Results"]) && $_SESSION["MySearch_t_articulo_Results"] != "")     {
      $MySearch->whereClause = $_SESSION["MySearch_t_articulo_Results"];
    }
    else     {
      $MySearch->whereClause = $MySearch_DefaultWhere;
    }
  }
  else     {
    $MySearch->whereClause = $MySearch_DefaultWhere;
  }
}
$MySearch->whereClause = str_replace("\\''", "''", $MySearch->whereClause);
$MySearchwhereClause = '';
?>


<?php
$maxRows_RecordSett_articulo = 10;
$pageNum_RecordSett_articulo = 0;
if (isset($_GET['pageNum_RecordSett_articulo'])) {
  $pageNum_RecordSett_articulo = $_GET['pageNum_RecordSett_articulo'];
}
$startRow_RecordSett_articulo = $pageNum_RecordSett_articulo * $maxRows_RecordSett_articulo;

mysql_select_db($database_MySQLconnect, $MySQLconnect);
$query_RecordSett_articulo = "SELECT id_cliente, company_name, cliente_calle, cliente_numero, cliente_local, cliente_poblacion, cliente_cp, cliente_pais, cliente_tel, cliente_fax, cliente_movil, cliente_personadecontacto, cliente_email, cliente_web FROM t_clientes ORDER BY company_name ASC";
setQueryBuilderSource($query_RecordSett_articulo,$WADbSearch1,false);
$query_limit_RecordSett_articulo = sprintf("%s LIMIT %d, %d", $query_RecordSett_articulo, $startRow_RecordSett_articulo, $maxRows_RecordSett_articulo);
$RecordSett_articulo = mysql_query($query_limit_RecordSett_articulo, $MySQLconnect) or die(mysql_error());
$row_RecordSett_articulo = mysql_fetch_assoc($RecordSett_articulo);

if (isset($_GET['totalRows_RecordSett_articulo'])) {
  $totalRows_RecordSett_articulo = $_GET['totalRows_RecordSett_articulo'];
} else {
  $all_RecordSett_articulo = mysql_query($query_RecordSett_articulo);
  $totalRows_RecordSett_articulo = mysql_num_rows($all_RecordSett_articulo);
}
$totalPages_RecordSett_articulo = ceil($totalRows_RecordSett_articulo/$maxRows_RecordSett_articulo)-1;
?>
please note this line
   
Code: [Select]
$MySearch->addComparisonFromEdit("company_name","S_articulo_esp","AND","Includes",0);//comparison list additions

because here is where I am getting confused . How can I add more fields to it?

Thanks

Hello everyone, I have been doing web developing for a little while and just recently decided to make the leap to developing standalone applications.  I started learning C++ and JAVA for this purpose, but quickly learned that PHP can also be used to this end, and since I am quite familiar with PHP, I thought it would make sense to start with PHP GTK.  But before I jump right in, I have a few questions that I would greatly appreciate some answers for:

Does PHP have any significant advantages/disadvantages over lower level languages such as C++ ?  I would imagine that PHP being originally designed for web programming would be less suited for stand alones.

I'm a little confused as to whether the GTK is a graphical user interphase software, the likes of QT and Netbeans,  or is it a markup language like HTML, where the widgets are generated with text commands?  Please I need a little clarification on that.  Also are there any other tools that need to be downloaded to get started besides the GTK?

Finally, am I supposed to learn OOP PHP to get going or is traditional procedural PHP sufficient?


Answers to any or all of the above questions and any other advice would be highly appreciated.

Thanks.

I've been coding PHP for some time and would consider myself to be at an intermediate level. I can write code to do what I need but it's probably not the best way to do it. I rarely see any code that I am not able to read, understand, or follow. I've created modifications for everything from vBulletin, WordPress, Kayako Support Suit, Magento, and more.

However, I've never really built a strong understanding around OOP. For example, let say you have the following classes:
_main
  -  db
  -  admin
  -  -  modules
  -  -  -  dashboard

How would you share the db connection with the dashboard class? I've been trying to read up on Dependency Injections and Singletons but I haven't found an article that has explained it on a level that I can understand. I get a feeling that most people who use OOP in PHP have a background in Java or C++ and are much more familiar with everything.

Could someone please explain this to me in simple terms or link me to an extremely well explained article that I'd be able to understand without a background in computer science?
Thanks
