passing variables to new window in php

[runway27]

1.

i have a self submitting form using POST
<form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="POST" id="test2" name="registrationform">

i am not using any javascript assuming javascript is turned off in a users browser.

i have a feature where in a user can click on an image to find out if a username is available or not. using javascript i am able to capture the value entered, pass the value entered by the user and open a new window and display a message with a php file if the username is available or not

however since i am not using javascript i used the following code to call the same php file which checks for the user name,

<a href="checkusername.php?usernameis="<?php echo($username); ?> target="_blank"> <img src="image.jpg"> </a>

however i am not able to pass the value of the username entered in the textfield by the user.

code in checkusername.php is

$username = $_GET["usernameis"]; and the remaining code to connect to database and display a message.

how can i pass the value entered in the textfield to checkusername.php when the image is clicked.

textfield is defined as follows = <input name="username" type="text" value="<?php echo($username) ; ?>" />


2.
i need to validate a password which can consist of both letters and numbers and should be between 5 to 10 characters only.

how can i rewrite the following preg_match to specify the condition of 5 to 10 characters only as presently it is not working

as i seem to be missing something in the syntax.

if($password == "" || !preg_match('/^[a-zA-Z0-9]{\(5)$|^\(10)}+$/', $password) )

please advice.

thanks.

For No1

Try changing:

[HTML]<a href="checkusername.php?usernameis="<?php echo($username); ?> target="_blank"> [/HTML]


into


[HTML]<a href="checkusername.php?usernameis=<?php echo($username); ?>" target="_blank">[/HTML]

Why dont you use a form with an image as the submit button?
[html]
<form name="someForm" action="somephppage.php" method="post">
<input type="text" name="username" />
<input type="image" src="locationOfImage.jpg" height=".." width=".." name="submit" />
</form>
[/html]

Try:
[php]
if($password == "" || !preg_match('/^[a-zA-Z0-9]{5,10}+$/', $password) )
[/php]
