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

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;

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.

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.

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?

What is the difference between these two lines


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

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

The Question

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)

?
