add http:// incase user forgets

[newb]

i was wondering how do i add http:// incase the user forgets to for forms?

Well.. you could use a substr() and cut the text and check the first 7 letters, if they aren't http:// you could add it
like this  $something = "http://".$something;


The code would be something like this?
[code=php:0]
<?php
$check_text = substr($link, 0, 7);

if($check_text != "http://")
$link = "http://".$link;

?>
[/code]

and if they forget www?

www wont matter anyways, http://google.com will make just as good as http://www.google.com :)

try this ok.
[code]
<?php

$url="www.google.com";

if(!eregi("^(http://)",$url)){

$rep=str_replace($url,"http://.$url",$url);
}

?>
[/code]

[code]
<?php

// if the user only puts in google.com replaced with http://www.google.com.

$url="google.com";

if(!eregi("^(http://www.)",$url)){

$replaced=str_replace($url,"http://www.$url",$url);

echo $replaced;

}

echo "<br>";

?>
[/code]

[code]
<?php

// if the user only puts in http://google.com replaced with http://www.google.com.

$url="google.com";

if(!eregi("^(http://)",$url)){

$replaced=str_replace($url,"http://www.$url",$url);

echo $replaced;

}

echo "<br>";

?>
[/code]

[code]
<?php

// if the user only puts in www.google.com replaced with http://www.google.com.

$url="google.com";

if(!eregi("^(http://)",$url)){

$replaced=str_replace($url,"http://www.$url",$url);

echo $replaced;

}

echo "<br>";

?>

[/code]
