[[SOLVED] Random Number of Forms on one Page]

I don't actually get what you want to do... But maybe this helps a bit:

 

<?php
$number = $_POST['num'];
$item   = $_POST['item' . $number];
?>

 

But I don't see much sense in it all... If you don't want that there are equal names in your code, you can also use a foreach on $_POST...

 

<?php
foreach($_POST as $key => $post) {

}
?>

 

Or if you want to check if there is anything posted at all you can use: if ($_SERVER['REQUEST_METHOD'] == 'POST') {}

 

Hope this is usefull

[extract text from html-fil]

In this case, I would mess a little with explode

explode(splitter, haystack);

 

When you explode, you chop a string in an array. so when you explode on > you can get the usefull things out with the keys...

For example:

 

<?php
$string = 'Here are more HTML tags ... <td>Example</td> ... Here are more HTML tags';
$string = explode('<td>', $string); // key 1 contains 'Example</td>' (key 0 is empty)
$string = $string[1];
$string = explode('</td>', $string); // key 0 contains 'Example'
$string = $string[0];
?>

 

Though you need to be carefull with the keys

You can write simple functions for this to make it an easier job, hope this function is usefull

[help!! validate a domain]

Hmm, why don't you use: gethostbyname('www.example.com');

It returns the ip of a website and when the website doesn't exists, it returns an IP that is the same for every other false website.

 

Hope this is usefull

// EDIT

 

Sorry I realised I missunderstood... Probably you don't want to check for the existence of a domain...

[breaking an setTimeout]

Hi, I was wondering if there is a possibility to stop or break an setTimeout
For example, when you have:

setTimeout('hello()', 5000);

hello() wil be executed in 5 seconds, but I was wondering if ik could be stopped when an other command is executed

Many thnx in Advance

[Inserting the ID to read]

Hi, I have a script that changes an element according to the id that is putted into the function, I am doing this with 'eval', as an example:

function changecolor(id) {
  id = eval("divitem_" + id);
  id.style.bgColor = '#000000';
}

this works fine though, but I was wondering if it could be done on the W3C standart, I tried this but it doesn't work:

document.getElementById('divitem_' + id).style.bgColor = '#000000';

Many Thnx in advance  :D

for example: calc($sum);

Many thnx in advance for the answers

[CSS in E-mail]

Unfortunatly that doesn't work to :(

But it has to be possible because in many newsletters there are links made with pseudoclasses...

[CSS in E-mail]

I have a simple script to send HTML emails but when I use CSS it doesn't reads the CSS...
When I put the style inside the tags, they work fine, but that's a bit hard when you have links, because here you also have the features hover, active etc. Here is my mail script:

$to = "example@example.com";
$from = "example@example.com;
$subject = "EXAMPLE";
$message = "

<!-- Put here your HTML code -->

";

$headers = "From: $from\r\n";
$headers .= "Content-type: text/html\r\n";

$success = mail($to, $subject, $message, $headers);

if ($success)
{
echo "The email to $to from $from was successfully sent";
}
else
{
echo "An error occurred when sending the email to $to from $from";
}
?>

I would like to know which solution is posible.
1. Is there some way to use hover and active etc in the <a style="""></a> tag?
2. Is there a possibility to set the content type also to CSS (for ezample: $headers .= "Content-type: text/html text/css\r\n"; which I've already tried but doesn't work)

Well many thnx to those who replie ;-)
