PHP - How To Handle Units Conversion?

I have just completed a modest way for Users to post Comments on Articles my website.

However, the thought occurred to me today, that I haven't given Users the ability to Preview or Edit their comments after submittal.

What is the best way to store info on a Comments Form so you can re-display it for Preview/Editing??  (I'm not really sure how the workflow would work for this?!)

Do I capture the Comments Form Data and store it in a Session?  Or in my Database?  Or do something else?

Security is always a concern of mine too!!

Thanks,


Debbie

How do I make my constructor work when I don't pass in an argument.  That is, it should efault to null.

Code: [Select]
class Something{
private $type=null;

public function __construct($t){
$this->type = $t;
}

public function setSomething($t){
$this->type = $t;
}

public function getSomething(){
if (is_null($this->type)) {
return "None for you!";
} else {
return "Something is " . $this->type . ".";
}
}
}

Hi,

New to coding so pls bear with me....

I am running into a continual issue that wonder if there is a better way to handle it.

When writing code that handles GET variables that have not been set I use the isset function with if statements to handle it, but my code looks like it is getting sloppy and I am having to repeat it a lot - for example:

Every time I simply want to call a class / function that I want to pass avGET i have to do the following:

Code: [Select]
if (isset($_GET["filter"])){$theFilter = $pageination->filter($_GET["filter"]);} else {$theFilter = $pageination->filter();}
Here is a copy of the class I have created (note sure if it works yet as not fully tested it)

Code: [Select]
class pageination {

private $recordLimit=100;

public function filter ($filter="") {
if ($filter!=""){
  $theFilter=" AND ".$filter;
  return $theFilter;
}
else {
return $theFilter="";
}
}

private function pageCnt ($pageCntRst) {
$pageCnt=intval($results[$pageCntRst]);
return $pageCnt;
}

public function pageNmLnk () {
echo 'Page: <a href="?pageStartListings=0&filter='. $_GET['filter'].'">1</a>';
}

//This loops through every 100 pages
public function pageNmLoop ($pageCnt) {
for ($n=1; $n<=$pageCnt; $n++){
if ($n > $recordLimit) {
break;
}

if ($n*$recordLimit==intval($_GET["pageStartListings"])){
$stylePg = 'style="border: 1px solid #aaaaaa; background-color: #CCCCCC; padding:3px; "> ' . $n+1 . '</a>';
}
else{
$stylePg = '';
}

echo '| <a href="?pageStartListings=' . $n*$recordLimit . '&filter=' . rawurlencode($_GET["filter"]) . ' " ' . $stylePg;

}
}


}

$pageination = new pageination ();
?>
I use the GET a few times in the code and I have to write a lot of code around the isset and if statements to handle it all the time - thinking there must be a better way to do this or a function that can be built to test it?

Any help is grateful in advance.

Hi all.

I'm new to PHP language and I'd like to know which is the best way to handle the user login.

With cookies or with sessions?

Do you know some example on the web that I could inspire on? I just know how to do it in both way, I just wanna know which is the best way and like to read some code written by a pro.

Hi All.

New at this, form is working perfect, then added recapthca, now it only handles recaptcha and not the form. not sure where the error is 

Dusting off my PHP skills after some time!   

How would I do this...

Code: [Select]
IF form was submitted
THEN do some PHP stuff and do not show the form again
ELSE display the form for the first time
Is it as simple as wrapping my HTML inside an If-Then-Else?

I have 2 PHP scripts : opendb.php and closedb.php

In opendb.php I have this code :

<?php
session_start();
$conn = mysqli_connect(................................);

// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
} else {
  echo "DB open.";
  $_SESSION['dbhandler'] = $conn;
}
?>

In closedb.php I have this code :

<?php
session_start();
$conn = $_SESSION['dbhandler']
mysqli_close($conn);
echo "DB closed";
?>
 

When I run opendb.php I get the expexted message "DB Open."

But when running the closedb.php ,   I get an error 500.

I was hoping to be able to pass the Handle, needed to operate in my database, between PHP scripts, by pushing it

into $_SESSION['dbhandler'] , and retreiving it in other scripts.

Is this possible ?

May you help me with how to get a file handle for a checkbox. I mean something that will output a 1 or 0...

thank you

Hi guys

On the edit profile page on my website, im trying to get is so that when the user first opens the page, if the database field reads "1" the checkbox is checked. However if the user unchecks it and makes a mistake on the form which returns an error, the checkbox remains unchecked. Also if the user unchecks the text box, the 1 in the database is changed to a 0. And vise versa.

The only way i have got it to work succesfully is by using the following:


<?php
$test = $_POST['test'];
$submit = $_POST['submit'];

if (!isset($test))

{

$test="0";

}

else

{

$test="1";

}

if ($submit)
{

mysql_query("UPDATE profiles SET test='$test' WHERE username='user'");

echo "ok";
}
?>
<html>
<form action="test.php" method="POST">
<input type="checkbox" name="test" <?php if ($submit) { if ($test=="1") { echo "checked='checked'";}} else { if ($row['test'] == "1") {echo "checked='checked'";}} ?> />
<input type="submit" name="submit" />
</form>
</html>


My problem is, i have about 60 check boxes on the page, and i dont really want to write the code below for all of them:

if (!isset($test))
{

$test="0";
}
else
{

$test="1";
}

Does anybody know a better way to do this so i dont end up with 420 lines of extra code?

Many thanks.

Well in my script exist certain objects being used everywhere, in main script files and class library files. A good example is this Page class:

Code: [Select]
<?php
class Page{
  public $type;
  public $name;
  private $title = "";
  private $content = "";
  private $date = "";
  private $links;
  private $sidebar;
  private $ads;

  public function __construct($page = ""){
      // Constructor method of page class
  }

    public function gettitle(){
     if(empty($this->title)) throw new Exception('The page has no title.');
     return $this->title;
  }
  
  public function settitle($title){
     $title = secure($title);
     if(empty($title)) throw new Exception('Cannot set title for this page.');
 else $this->title = $title;
  }
  
  public function getcontent(){
     if(empty($this->title)) throw new Exception('The page has no content.');
     return $this->content;
  }
  
  public function addcontent($content, $overwrite = FALSE){
     $content = secure($content);
     if(empty($this->content) or $overwrite == TRUE) $this->content = $content;
 else $this->content .= $content;
  }

  public function getlinks(){
     // the method that grabs user links
  }

  public function getsidebar(){
     // the method that loads sidebar
  }

  public function getads(){
     // the method that shows ads
  }

  public function display(){
     // the method that format pages and brings everything together
  }
}
?>

Now lets say I have other classes such as User, Message and Item, a page object will need to be used inside some of their methods so that the page title/content can be modified when necessary. This seems to be quite problematic to me, since I have to declare this Page object global in every method that uses it.

Similar problem occurs with my database object, and its even more annoying since almost half of my class methods need to use database queries and commands.

So I was wondering... Is there a better way for me to handle these system objects such as Page and Database rather than having to declare them as global inside every single method that deals with them? Please help...

I need to come up with a better way to do this. Currently I have a script which is a form and the user enters their email address, and their password in the database is sent to the email address. Problem is the password is MD5 hashed, so it's hashed when sent to their email. I am sure there is a better way to do this. Also, I am capturing a Security Question and Answer in the initial profile form that the user fills out, so I need to incorporate this as an extra layer of security. Please let me know of the methods for doing this.

Thanks in advance!

I have a script that takes a 2 or 3 page pdf, uploads it and hashes the file name to something that isn't guessable. 

We now want to add an image of each of the PDF for users who don't have Adobe Reader.  Some pdf's will be 2 and some 3 pages.

Should I:
A) Let convert name the different pages "*-0.jpg, *-1.jpg..." and then use a recursion function (it's already written for another reason) to crawl the folder,
B) Use a PHP/PDF library to determine the number of pages, then add the value to the database's corresponding row.
C) Use a hybrid of both
D) Any better ideas???

Thanks
