[SOLVED] extract website address from textbox and redirect to it

[jpedrofs]

Hey guys,

 

I am a beginner trying to figure out how to create a button that redirects you to a website address extracted from a textbox.

 

My attempt goes below:

 

<form method="post" action="<?php $_POST['textbox']; ?>" />

<input type="text" name="textbox" id="textbox" />

<input name="criarblog" type="submit" id="submit" value="submit" />

</form>

 

I haven't managed to put it working.

 

Thanks for any help,

 

Pedro

So you want the user to enter the address, www.domain.com, into a text box and have them taken to that site?

Where is the information in the text box coming from?

[jpedrofs]

Hi adam and suttercain,

It is as you say suttercain, the information comes from a textbox that is available in the webpage.

The user introduces an address in the textbox and when the submit button is clicked, there is a redirection to the webpage in the textbox.

this may work not 100% sure though

 

<?php
$a= $_POST[‘textbox’];

if(isset($_POST[‘textbox’]))
{
header('Location: $a');
}
else
{
?>
<form action="<?=$_SERVER["PHP_SELF"]?>"...
<input type="text" name="textbox" id="textbox" />
<input name="criarblog" type="submit" id="submit" value="submit" />
</form>
<?php
}
?>

It is already redirecting to:

 

http://mydomain.com/index.php?textbox=http://whatever.com&criarblog=submit

 

but not yet to:

 

http://whatever.com

 

Any hints?

post all the code. Can't help without see whats going on

[jpedrofs]

I just introduced your code suggestion and tried some tweaks, but came back to your original code:

 

<?php

$a= $_POST[‘textbox’];

 

if(isset($_POST[‘textbox’]))

{

header('Location: $a');

}

else

{

?>

<form action="<?=$_SERVER["PHP_SELF"]?>" />

<input type="text" name="textbox" id="textbox" />

<input name="criarblog" type="submit" id="submit" value="submit" />

</form>

<?php

}

?>

[adam291086]

change to this

<?php
$a= $_POST[‘textbox’];

if(isset($_POST[‘textbox’]))
{
header('Location: http://$a');
}
else
{
?>
<form action="<?=$_SERVER["PHP_SELF"]?>" />
<input type="text" name="textbox" id="textbox" />
<input name="criarblog" type="submit" id="submit" value="submit" />
</form>
<?php
}
?>

I want to clear something up for jpedrofs.

I can see what you're attemping to do, but your understanding is skewed.

The first time you load your form it looks something like this :

<form method="post" action="" />
<input type="text" name="textbox" id="textbox" />
<input name="criarblog" type="submit" id="submit" value="submit" />
</form>

 

When you click the submit button it will post to the page "" (blank). Now assuming the web browser obliges and guesses that you actually wanted to POST to the same page you are on, you might get lucky, and it'll reload the page you were just on, POST'ing the contents of the textbox to itself. Thus on you 2nd run your form will look something like this :

 

<form method="post" action="whatever-i-typed-in-the-previous-box.com" />
<input type="text" name="textbox" id="textbox" />
<input name="criarblog" type="submit" id="submit" value="submit" />
</form>

 

And on clicking submit again, you'll get lucky and end up on the page you wanted.

 

Have a think about the above, and i'm sure you'll start to see where you were going wrong.

[jpedrofs]

Thanks for your thoughts. I will continue to work on it and will get back to you guys.

correct way.......

 

<?php
ob_start(); // incase
if($_POST['submit']){
$textbox=$_POST['textbox'];
header("Location: $textbox");
exit;
}
ob_flush(); // incase
?>
<form method="POST" action=" ">
<input type="text" name="textbox" >
<input name="submit" type="submit" value="submit">
</form>

[jpedrofs]
