PHP - Quick And Dirty Regex Question

What is the difference between these two lines


Code: [Select]
!isset($_POST[$requiredField])
and

Code: [Select]
!$_POST[$requiredField]

how to open a site with curl that has frames ?

when ive tried it gives "your broswer does not support frames" ...

I am starting to learn PDO by re-writing one of my existing scripts. Do I still need to validate $_GET or does PDO do the work for me?  Currently I am using:

Code: [Select]
$id = $_GET['id'];

$sth = $dbh->prepare('DELETE FROM van_reservations WHERE id = :id');
$sth->bindParam(':id', $id, PDO::PARAM_INT);
$sth->execute();

I used to validate by using this:

Code: [Select]
$id = isset($_GET['id']) && is_numeric($_GET['id'])?(int) $_GET['id']:0;

code

<?php
//storecodefound.php v1.0
//purpose is to store the http refer and the code associated with the site to a db to be collected and verified by submitcode.php
$code = $_GET['code'];
$site = $_SERVER['HTTP_HOST'];


//check to see if the code already present
$connect = mysql_connect("localhost","root","") or die (mysql_error());
$check = mysql_query("SELECT code FROM hunter.codes WHERE code='$code'") or die (mysql_error());
$row = mysql_num_rows($check);
echo "result of \$row is ".$row;
echo "<br />";
if ($row = 0) {
//insert into db cause it's not there
mysql_query("INSERT INTO hunter.codes (id, code, site)
VALUES ('','$code','$site')") or die (mysql_error());
}
else {
//echo it's already here
echo "Code already found on server!";
}





?>

my question is the result of $row is infact 0 and the if statement says if $row is 0 to insert into db and instead it's given me the code is already found?

Is there a way to only output the first, say, 30 words of a variable? I have a way to do it in mind, but seems like it's messy and not practical.

Any suggestions?

E.g:

WITHOUT LIMIT: Welcome to my store. Would you like to buy something? We have really good noodles and fishes in doodle pools.
WITH LIMIT: Welcome to my store. Would you like...

Sort of like a short preview.

Does storing multiple values in 1 database field with a varchar let's say set at 150, all separated by
"|'s" so I don't have to create a field name for each one is it better performance wise or no? (storing 6-7 different |'s that will be outputted with a array ofc)

?

hey! I have a site where I want to use multiple issets at the same time, like if I have four buttons and four issets:
if(isset($_POST['one']))
{
echo '<div class="example_box">one</div>';
}

if(isset($_POST['two']))
{
echo '<div class="example_box">two</div>';
}

if(isset($_POST['three']))
{
echo '<div class="example_box">three</div>';
}

if(isset($_POST['four']))
{
echo '<div class="example_box">four</div>';
}


but for some reason it seems like only one isset can be activate at a time, is there any way to work this out or something :s?

I've tried some variants of elseif stuff and such, but yeah, I'm pretty new at this stuff

hi.
when i get into some function manual and there is a note says.
Quote

This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.

.
is that meaning that after 5.3.0 version this function will not be supported?
thanks , Mor.

Hi, I've seen code like this multiple times, but I don't really know what it means.

function funcName(&$something) {
    // whatever
}

What exactly does the "&" do before the variable?

Hi guys/girls,
any pointers on this would be greatly appreciated.
basically i have a table called HORSES with 2 fields: HORSE_ID and HORSE_NAME.
I want to create a page which dynamically shows all the horse ID's, then a checkbox, then the horse names which can be edited.
You can then edit a horse name, click the edit checkbox, and post the form to edit the database.
The Form shows the fields easily enough, but doesnt update the database for some reason.
Anyone got any ideas?

<?php
      include("..\connection\connection.php");
     $conn = oci_connect($UName,$PWord,$DB)
      or die("Couldn't logon.");
  if(empty($_POST["check"]))
  {
    $query = "SELECT * FROM HORSE ORDER BY HORSE_NAME";
    $stmt = oci_parse($conn,$query);
    oci_execute($stmt);

?>
    <form method="post" action="horsemultiple.php">
      <table border="1" cellpadding="5">
      <tr>
        <th>Horse_ID</th>
        <th>Edit</th>
        <th>Horse Name</th>
      </tr>
<?php
      while ($namearray = oci_fetch_array ($stmt))
      {
?>
        <tr>
          <td><?php echo $namearray["HORSE_ID"]; ?></td>
          <td align="center">
            <input type="checkbox" name="check[]"
              value="<?php echo $namearray["HORSE_ID"]; ?>">
          </td>
          <td align="center">

<input type="text" size="5"
            name="<?php echo $namearray["HORSE_ID"]; ?>"
            value="<?php echo $namearray["HORSE_NAME"]; ?>">

          </td>
        </tr>
<?php
      }
?>
      </table><p />
      <center>
        <input type="submit"
          value="Update Selected Horses">
      </center>
    </form>
<?php
    oci_free_statement($stmt);
  }
  else
  {
    foreach($_POST["check"] as $id)
     {

   $query = "UPDATE HORSE
         set HORSE_NAME = ".$_POST[$id].
         " WHERE HORSE_ID ='".$id."'";
       $stmt = oci_parse($conn,$query);
       oci_execute($stmt);
       header("location: ../horse.php");

     }
  }
  oci_close($conn);
?>

Can I replace the set message text for $body and $subject with $_POST['message']; $_POST['subject']; so I can get a users input from a html form via php as the action.  Instead of the set text in the script.
As seen http://email.about.com/od/emailprogrammingtips/qt/PHP_Email_SMTP_Authentication.htm

Hi
I have a quick question. I want my javascript to be able to access my php page because my php page has the coding to access the database and then it has to give me a list of the stuff in the database the alert box.
This is the code that I have. I know that I can use it but I'm not sure how to go about it.

getPHPResponse=function(){
   
   
   var url="/countries/ajax_return_response";


       $.post(url, {'format': 'JSON', 'countries': '$countries'}, function(data){
      //this is where jsvascript must do something

              alert(data);
   });
}

Hello everyone,

With the recent time change, I found a new problem with my code.  I think I have it fixed by utilizing the "date_default_timezone_set()" function, but I have a question.  Does this php time/date function automatically account for daylight savings time, is it something that will have to be adjusted in my code?  I think I can figure out how to adjust it if it's needed, but I don't want to have to do the work if it is updated automatically.  Thanks for any help.

quick question... I have a column in my table called views. I want to reset the column to 0 for each row in the table. What's the easiest way to do this?
